When Li Yi rushed to the ancient and mysterious castle like a black gust of wind, the night was like an overturned ink bottle, so thick that it could not be dissolved, and it was heavily pressed over the castle. The surroundings were as quiet as a vacuum, with only a few owls screaming from time to time in the distance, breaking the dead silence like sharp arrows. The outer walls of the castle were covered with dark green moss, and the mottled stones were like wrinkled faces, silently telling the long past of the years. The towering spires were shadowy in the hazy night, just like giant hands reaching out from the dark abyss, trying to grab the ethereal moonlight. As soon as Li Yi approached the castle gate, a stale and rotten smell wrapped in a faint smell of blood came to his face, making him frown slightly. The two extremely heavy iron doors, which looked like city gates, were tightly closed. The copper rings on them flashed cold lights like ghost fires under the faint light, just like two mysterious eyes hidden in the dark, peeping at the world. Li Yi raised his hand and held the copper rings steadily, knocking gently. The dull sound was like an ancient call, echoing for a long time inside the castle. After a long time, an old servant who was trembling like a candle in the wind opened the door to the mysterious world for him. The old servant's face was as pale as paper, without any blood, and his eyes were full of fear, like a frightened hare. He led the way tremblingly in front and took Li Yi to the depths of the castle. Along the way, Li Yi keenly noticed that the flames of the candlesticks on the wall seemed to be pulled by a pair of invisible ghostly hands, swaying and uncertain, and could be swallowed by the darkness at any time. The owner of the castle had been waiting anxiously in the hall like an ant on a hot pot. He was thin, like a dry tree that had been dry for a long time, and his eyes were full of anxiety and uneasiness, as if he was shrouded by a dark cloud. When he saw Li Yi, he felt like he had found a life-saving straw, and he hurriedly told him about the endless strange things that had happened in the castle recently. In addition to the paintings that moved on their own for no reason, the walls oozing blood like injured beasts, and the strange footsteps that echoed faintly in the silent corridors, every night at midnight, there would be faint painful groans from the basement of the castle, as if coming from the underworld, as if countless wronged souls were suffering inhumane torture in the dark underground. When Li Yi heard this, he secretly thought that this castle must be hiding an unknown old secret, and judging from this series of creepy phenomena, the yin energy here is as heavy as a mountain, and I am afraid that it will soon face a thrilling and extremely difficult battle. He quickly took out the compass from his backpack, and saw that the compass needle was spinning wildly and irregularly like a crazy dancer. The yin-yang fish pattern on the dial seemed to be shrouded in a thick layer of evil haze, dim and dim, as if it had lost the ability to guide the direction. Li Yi followed the direction indicated by the trembling compass needle, and walked slowly to the basement carefully, as if he was stepping into a minefield. The stairs in the basement were narrow and steep, like a steep path leading to hell. The walls were wet and constantly exuded a pungent musty smell. Every step he took would echo slightly under his feet, as if a pair of eyes hidden in the dark were staring at his every move. Finally, he arrived at the door of the basement. A piercing chill hit him like a surging tide. Li Yi stared at it and saw that the door was engraved with strange and bizarre symbols. Those symbols were like twisted and winding venomous snakes, or some ancient spells from ancient times that were covered by the dust of time. They exuded a chilling and creepy atmosphere. He approached the door and, relying on the profound knowledge accumulated from years of studying Yin and Yang metaphysics, carefully identified and found that these symbols were closely related to the mysterious theory of the five elements. It seemed that someone had deliberately set a rock-hard seal in the past, but now, the seal seemed to be destroyed by a pair of evil hands, causing the evil hidden underground to overflow like a flood. Li Yi took a deep breath, as if to absorb the righteousness between heaven and earth, and resolutely pushed open the door of the basement. The house seemed to be shrouded in a thick layer of fog, and the sight seemed to be blocked by a layer of gauze. Only some vague, ghostly outlines could be seen. In the corner, the piles of shabby sundries seemed like dormant prehistoric beasts, exuding a mysterious and dangerous atmosphere in the mist. Li Yi was like an explorer looking for treasure, carefully searching among them. Suddenly, his foot seemed to be tripped by something. He lowered his head and looked carefully. It turned out to be a broken stone tablet. The handwriting on the tablet seemed to be eroded by the sharp blade of time and was incomplete, but Li Yi could still peek out some clues from it with his keen insight. As mentioned above, hundreds of years ago, the owner of this castle seemed to be possessed by a greedy demon. In order to obtain mountains of wealth, he colluded with an evil cultivator and carried out a cruel and outrageous blood sacrifice. Countless innocent lives were like withered flowers, dying tragically in this bloody sacrifice. Later, a Taoist priest who traveled around the world and had a celestial spirit passed by this place by chance. He used his all-powerful magic power to seal the evil spirit in this dark basement, and left a solemn warning that if future generations did something unjust again, the seal would be broken like a fragile eggshell, and the disaster would befall the world like a turbulent tsunami. It seems that the chaos in the castle today is the result of the evil that was planted back then. Li Yi already had a clear plan in his mind. He knew that in order to quell this disaster that seemed like the end of the world, he had to find the magic weapon left by the Taoist priest, re-reinforce the seal that seemed to be crumbling, and then, with compassion, save these resentful souls who were like lost lambs. He was like a hound with a keen sense of smell, exploring around in the basement, relying on the vague guidance of the compass, and finally found a small cave that was extremely secret and like a paradise behind a dark wall that seemed to be integrated with the darkness. In the cave, there are several mysterious items: a peach wood sword, the blade seems to be engraved by time, full of runes, and the texture of the peach wood seems to flow with wisps of righteousness like the morning light; a simple and heavy statue of the Three Pure Ones, which seems to carry the great way of heaven and earth. Although it has gone through a long time, the eyes of the statue still reveal the majesty of the gods overlooking the world, as if always watching the good and evil in the world; there is also a Taoist scripture with yellowed paper, which seems to be forgotten by time, and records many mysterious yin and yang secrets and methods of salvation that seem to come from the fairy world. Li Yi, like a devout believer, picked up these instruments, strode out of the cave, and set up an altar in the center of the basement as if a sacred ceremony was held. He placed the statue of the Three Pure Ones in the middle as if he was worshipping a god, and placed the peach wood sword aside as if it were a guardian magic weapon. Then, as if reading a heavenly book, he opened the Taoist scripture and began to recite the scriptures. As his low and rhythmic voice, as if from ancient times, sounded, the mist in the basement seemed to be injected with life and gradually surged up, like a group of elves dancing happily. Suddenly, a black shadow, like black lightning, jumped out from the corner of the wall, bringing a strong and pungent smell like a rotting corpse, and rushed straight to Li Yi. Li Yi seemed to have foresight, and quickly picked up the peach wood sword, like a god descending from heaven, and shouted: "Hurry up and obey the order!" In an instant, the peach wood sword was like a lit torch, and the light was instantly bright. The black shadow seemed to be afraid of this sacred light, and it circled in the air like a lost lonely bird, and then retreated into the dark like a defeated soldier. However, things are like turbulent waves, one wave has not settled, and another wave has risen. As Li Yi continued to recite the scriptures, the temperature around him dropped sharply as if he had fallen into an ice cellar. The blood seeping from the walls was like a flood that had burst its banks, becoming more and more violent, like a fountain of blood gushing out. The ground also seemed to be shaken by an angry beast and began to tremble slightly, as if something was struggling underground like a trapped beast. Li Yi was like a wise man who had insight into the world, realizing that the resentment of these wronged souls was like an endless abyss, unfathomable, and difficult to appease with simple salvation. He was like a scholar seeking the truth, and he opened the Taoist scriptures again, carefully searching, and discovered an ancient and mysterious "Yin Yang Reverse Soul Formation" that seemed to have been lost for a long time. He needed to use his own spiritual power that seemed to be like a burning soul as a guide, and with the help of the power of the five elements that seemed to control the heaven and earth, to completely resolve this resentment that seemed to be like a mountain pressing down on one's head. Li Yi, like a warrior who was desperate, decided to give it a try. He followed the doctor's advice and the instructions in the scriptures. He placed items representing gold, wood, water, fire, and earth in the four corners of the basement, like a battlefield. He cut his finger like a sacrifice, dripped the blood that seemed like the essence of life on the heart-like array eye, and activated the array like a sleeping beast with his own yang energy like the scorching sun. In an instant, the whole basement seemed to be descended by day, shining with light, as if countless stars were flashing in it, and the yin-yang fish pattern appeared in the air like a reborn phoenix, slowly rotating. The roar of the wronged souls was like surging waves, one after another, but under the suppression of the array like an indestructible wall, it gradually weakened. Li Yi, like grabbing a life-saving straw, seized the opportunity, accelerated the speed of chanting, and devoted all his energy to transcend these wronged souls who were like lost lambs. As a strong light flashed past as if piercing the night sky, the figure of the wronged soul turned into spots of light and dissipated in the air like purified dust. The strange vision in the basement subsided like a dispelled haze, the walls no longer bleed, the paintings return to their original positions like wanderers returning home, and the strange footsteps disappear without a trace like driven ghosts. The owner of the castle knelt down to thank him excitedly as if he had witnessed a miracle, and Li Yi hurriedly helped him up as if he was supporting a wounded person. Just as Li Yi was about to take a short break like a tired traveler, the ringtone of his cell phone rang again at an inopportune time, like a death warrant. On the other end of the phone, a hoarse and anxious voice as if polished by sandpaper came from an ancient village in a remote mountainous area that seemed to have been forgotten by time. The villagers have been plagued by "ghost fire" as if they were haunted by demons recently. Every night, green flames like ghost fires will be ignited in the fields. The livestock seem to be possessed by evil spirits and go crazy for no reason. Some people seem to be entangled in nightmares, seeing the miserable faces of their deceased relatives in their dreams and begging for help. Li Yi hung up the phone, his eyes were like a firm rock, he packed his bags, and headed towards the unknown village as if he was going to the battlefield. He knew that this road of yin and yang metaphysics, the journey of exploring the secrets of exorcism, was like an endless journey with no end... When Li Yi arrived at the village, it was dusk, and the afterglow of the sunset was like a golden veil, dyeing the village golden. This should have been a peaceful and peaceful picture like a paradise, but the tension and fear in the air were like a sharp blade, breaking this beauty. At the entrance of the village, several old men stood there with solemn faces like sculptures, their eyes full of worry. When they saw Li Yi, they came forward as if they had seen a savior, telling about all the strange things that had happened in the village during this period. Li Yi walked into the village like a traveler exploring a mystery, and found that the layout here was quite peculiar. The houses in the village were scattered and arranged, but they seemed to be carefully arranged by an invisible big hand, faintly forming a shape similar to the Bagua. He was moved in his heart, could it be that the construction of this village was inextricably linked to the art of Yin and Yang Bagua? He took out the compass like a detective seeking the truth, and the pointer trembled slightly, showing that the aura here was like a disordered silk thread, and the yin and yang were unbalanced. Following the guidance of the compass, Li Yi came to an ancient well in the center of the village as if he was attracted by a magnet. The ancient well seemed to be shrouded in fairy air, with mist rising, and from time to time, a trace of cold air from the wellhead seemed to come from the underworld, as if it was the entrance to the Nine Netherworld. Li Yi approached the ancient well and looked down. The water in the well was dark and deep, like a cursed magic mirror that could not reflect anything. He squatted down and carefully observed the edge of the well like an archaeologist. He found some small symbols engraved on it that looked like ant footprints. These symbols were somewhat similar to those he had seen in the basement of the castle before. They were all ancient and mysterious, as if they came from ancient times, and were related to the cycle of life and death, and the transformation of yin and yang. Li Yi thought to himself that this ancient well might be the key to the problem. He asked the villagers about the origin of the ancient well. An old man, like a historian recalling the past, recalled that the ancient well had a history of hundreds of years. It was said that the ancestors of the village were like guards to protect their homes and built it to suppress the evil spirits underground. There was also an Indian priest who was like a god descending to the world and set up a magic circle here. But time is like a ruthless stream, changing constantly, many things have been forgotten. In recent years, young people in the village have gone out to work like birds chasing the trend, and have become increasingly indifferent to these traditional customs. Perhaps this has touched some taboos, which has brought disaster. Li Yi decided to go down the well like an adventure hero to find out what was going on. He found a rope, tied it around his waist, and asked the villagers to help him put it down like angels. As he slowly went deeper into the well, the chill became more and more intense like a cold venomous snake, and there came to his ears a gloomy sound like the whisper of a wronged soul. At the bottom of the well, there was a thicker fog, and the sight seemed to be swallowed by the darkness, almost zero. Li Yi was like a blind man groping for treasure, groping forward, and suddenly, he touched a hard object, and when he looked closely, he saw that it was a rotten wooden box that seemed to have been eroded by time. Opening the wooden box, there are several artifact-like items inside: an eight-diagram mirror, the mirror surface is a little blurry, but you can still feel the powerful spiritual power contained in it, which is like the power of the gods; a string of Buddhist beads, each bead is round and smooth, as if bathed in the Buddha's light, emitting a faint Buddha's light, as if it can dispel all evil spirits in the world; there is also a yellowed talisman paper that seems to be covered by history, with a complex pattern like a heavenly book drawn on it. Li Yi recognized that this is a "suppressing evil talisman" made by an expert. Li Yi is like a warrior who has obtained a magic weapon. He picked up these magic weapons and prepared to return to the ground like a hero returning in triumph. However, at this moment, the giant beast at the bottom of the well, which seemed to be awakened, suddenly shook violently, as if some giant beast had awakened, and a strong suction came from the depths of the well, trying to drag him into the endless abyss like a drowning man. Li Yi was startled. He grabbed the Buddhist beads as if he had grabbed a life-saving straw and recited the mantra of rebirth. The Buddhist beads were like activated holy objects, shining brightly, offsetting some of the suction. He took the opportunity to escape from the tiger's mouth, grabbed the rope, and quickly returned to the ground with the help of the villagers. After returning to the ground, Li Yi set up an altar next to the ancient well as if he was holding a sacred ceremony. He hung the Bagua mirror above the wellhead like a sky lantern to reflect the evil spirit; placed the Buddhist beads in the center of the altar as if it were a treasure to purify the surrounding aura with its Buddha light; and then attached the evil-suppressing talisman to the edge of the well as if it were to seal the devil to reinforce the seal. Then, he began to recite scriptures and perform the art of Yin-Yang metaphysics to reconcile the Yin-Yang here. As he cast the spell, the "ghost fire" in the village gradually extinguished like a flame that had been extinguished, and the livestock also seemed to be relieved of the spell and returned to peace, and the villagers no longer had strange scenes in their dreams. The crisis was temporarily resolved, but Li Yi knew that to completely solve the problem, the villagers needed to regain their faith, regain their awe of traditional culture, and protect the yin and yang balance of this land. Just as he was about to instruct the villagers on relevant matters like a teacher, the ringing of the mobile phone broke the calm again, this time from an abandoned old house. It is said that on rainy nights, the doors and windows of the old house would open and close automatically, and there would be bursts of crying like children, and unidentified black shadows would wander around the house like ghosts. Li Yi hung up the phone with a firm look in his eyes, and ran to the next mysterious place without hesitation. His adventure continued...
