Lin Tian stood at the entrance of the stone cave and took a deep breath, sensing the faint fluctuation of spiritual energy emanating from within. This spiritual energy was different from the thick one outside. It carried an ancient aura, as if it had been silent in this land for tens of millions of years. Lin Tian's heart stirred. He knew that this stone cave was no ordinary place but hid some important secret, perhaps an opportunity leading to a higher realm. After regulating his breath for a moment, Lin Tian decided to enter the stone cave for exploration. To deal with potential dangers, he took out a protective talisman from the storage bag. This talisman was obtained by him by chance and could resist a fatal attack for him at a critical moment. Holding the talisman in his hand, Lin Tian felt a bit relieved. He knew that the more fully prepared he was, the greater the chance of winning when facing unknown risks. The light in the stone cave was dim, but for cultivators, seeing things wasn't a big problem. The cave walls were covered with a layer of faint moss, emitting a weak fluorescence that illuminated the way forward. Lin Tian walked steadily, lifted his feet gently, and slowly advanced along the winding cave passage. With each step, he was extremely cautious. Although the surrounding environment seemed calm, it faintly exuded an uneasy atmosphere. At the end of the cave passage, there seemed to be a weak light flickering. Lin Tian quickened his pace and carefully approached. After walking for about the time it takes to burn an incense stick, he finally reached the end of the cave passage. It was an open space. Several crystals were embedded on the surrounding stone walls, emitting a soft light that illuminated the entire cave. Lin Tian's gaze quickly swept across the entire cave. He noticed that in the center of the cave, there stood an ancient stone platform. The stone platform was carved from unknown black rocks and was covered with traces left by years, seemingly having undergone the baptism of countless years of wind and frost. Around the stone platform, nine stone pillars were neatly arranged. Each stone pillar was engraved with ancient runes. These runes were similar to those he saw on the mountain path but were more complex and profound, faintly emitting an awe-inspiring aura. On the top of the stone platform, a jade slip emitting a faint golden light was placed quietly. Lin Tian's heart stirred. This jade slip seemed ordinary, but he could sense the powerful fluctuation of spiritual energy within it. Obviously, it wasn't an ordinary item. Around the jade slip, there seemed to be an invisible force guarding it, making the entire stone platform exude an inviolable dignity. Lin Tian didn't rush forward blindly. He knew that in a place like this, there were often great dangers hidden. To avoid triggering possible prohibitions, he decided to first explore the surroundings to look for possible clues. Lin Tian walked slowly around the stone platform, carefully observing the runes on each stone pillar. These runes were arranged extremely neatly, as if they were part of some formation. Lin Tian knew a little about formations. He found that these runes seemed to be used to maintain the barrier around the stone platform, and that invisible force was precisely stimulated by these runes. "This is a sealing formation." Lin Tian's heart shuddered. Although his understanding of formations was limited, based on years of cultivation experience, he could tell that the design of this formation was extremely exquisite. Its purpose seemed to be to seal some powerful existence or protect the jade slip from external disturbances. Lin Tian continued to observe along the stone pillars. He noticed that at the bottom of each stone pillar, there seemed to be a groove. The shapes of these grooves were different, as if they were used to inlay some specific items. Lin Tian frowned slightly. He couldn't help but think that these grooves might be the key to activating the formation, but he didn't have the appropriate items in his hand and couldn't try rashly. After thinking for a moment, Lin Tian decided to first inspect the surroundings of the stone platform to see if he could find more clues. Just when he bypassed the last stone pillar, he suddenly felt a strange fluctuation. This fluctuation was extremely weak but was full of a dangerous aura, as if warning him not to approach. Lin Tian immediately stopped, turned around, and carefully sensed the source of the fluctuation. He found that this fluctuation seemed to come from beneath the stone platform. There faintly revealed a strange force, as if hiding some powerful existence. Lin Tian was vigilant in his heart. He didn't act rashly but first activated the protective talisman in his hand in case of need. After doing this, he slowly walked towards the stone platform, attempting to uncover the hidden secret beneath it. Lin Tian stood in front of the stone platform, sensing the strange fluctuation coming from below. He knew that there was most likely some powerful force sealed here, and once triggered, the consequences would be unpredictable. However, Lin Tian didn't retreat because of this. On the contrary, his heart was filled with a strong curiosity. This unknown force might be the key to breaking through his current cultivation level. Lin Tian took a deep breath, calmed the fluctuations in his heart, and then slowly reached out and gently touched the surface of the stone platform. The stone platform was cold and hard, and its surface was covered with cracks left by years. However, the moment Lin Tian touched it, he felt a powerful repulsive force coming from deep within the stone platform. That repulsive force was extremely powerful and almost bounced Lin Tian's hand away in an instant. Even the true essence within his body was affected and fluctuated. Lin Tian was startled and knew that there was definitely something extraordinary beneath this stone platform. It was most likely an infinitely powerful treasure or a powerful monster. He didn't try to directly touch the stone platform again but took a few steps back and concentrated on observing the changes around. After a moment, the runes on the stone platform suddenly began to emit a weak light. The light was extremely faint at first, almost imperceptible. But as time passed, the light gradually strengthened and finally formed a faint halo that surrounded the entire stone platform. Lin Tian's heart shuddered. He knew that the power beneath the stone platform was awakening, and this halo was most likely the last barrier of the sealing force. Once the halo was completely activated, the seal would be lifted. At that time, no matter what was sealed, it would reappear in the world. "It seems that a way must be found to lift this seal." Lin Tian thought to himself. He knew that lifting the seal might bring great danger, but if he succeeded, he would most likely obtain unimaginable benefits. Lin Tian looked around again and noticed those grooves at the bottom of the stone pillars. He guessed that these grooves were most likely the key to lifting the seal. If he could find the corresponding items, he might be able to smoothly lift the seal. Lin Tian stood in front of the stone platform, took a deep breath, and had already made a decision in his heart. He decided to first look for possible unsealing items in the cave instead of rashly trying to break the seal. After all, this ancient formation most likely contained some self-destructive mechanism. Once forcibly broken, the consequences would be unimaginable. Lin Tian walked slowly along the edge of the cave, carefully observing every corner. He knew that in such an ancient cave, there were often some hard-to-notice secrets. Only by being careful enough could these secrets be discovered. After walking for a while, Lin Tian discovered an abnormal place in a corner of the cave. It was a huge stone slab covered with thick moss. The surface seemed ordinary, but Lin Tian's spiritual sense captured a faint fluctuation of spiritual energy, as if there was some special item hidden beneath the slab. Lin Tian walked to the stone slab, reached out and gently brushed away the moss on the surface. As the moss dispersed, the patterns on the stone slab gradually appeared. Those patterns were extremely complex, presenting a strange rune shape, very similar to the runes on the stone platform. "Sure enough, there's something else going on here." Lin Tian was secretly delighted in his heart. He knew that beneath the stone slab, there was most likely a key item to lift the seal. He didn't act hastily but first carefully set up a defensive prohibition to prevent triggering any danger during the process of uncovering the stone slab. After doing this, Lin Tian slowly reached out and gently pressed the edge of the stone slab, preparing to uncover it. However, the weight of the stone slab exceeded Lin Tian's expectation. It was incredibly heavy. Lin Tian exerted all his strength and managed to barely move it a little. Through that gap, Lin Tian saw a faint light coming from beneath the stone slab. Lin Tian's heart stirred. He increased his strength and finally moved the stone slab completely. Beneath the stone slab was a small depression. In the depression, a jade pendant emitting a faint green light lay quietly. The jade pendant was completely green, with a warm texture. Its surface was carved with complex patterns, which were very similar to the runes on the stone platform, obviously coming from the same source. The jade pendant emitted a faint fluctuation of spiritual energy. Obviously, it was an extremely precious magical tool. Lin Tian carefully took out the jade pendant and felt the powerful force within it, secretly amazed in his heart. He knew that this jade pendant was most likely the key to activating the sealing formation, and to lift the seal, it must be corresponding and inlaid into the grooves on the stone pillars one by one. Lin Tian held the jade pendant and slowly walked back to the stone platform. He stood in front of the stone pillar and carefully observed the shape of each groove, attempting to find the groove that matched the jade pendant. However, the shapes of these grooves were different and didn't seem to completely match the shape of the jade pendant. Lin Tian frowned. He realized that perhaps with just one jade pendant, the seal couldn't be completely lifted. These grooves most likely corresponded to multiple similar jade pendants, and these jade pendants were scattered in various corners of the cave. Only by finding all of them and installing them correspondingly could the seal be completely lifted. "It seems that other jade pendants still need to be found." Lin Tian thought to himself. He decided to continue a more detailed search in the cave to see if he could find more clues. However, just when he turned to continue the exploration, he suddenly felt the jade pendant in his hand tremble slightly. Immediately after, the runes on the stone pillar suddenly flashed. Lin Tian immediately realized that this jade pendant had already resonated with the sealing formation and perhaps could be tried to be embedded into the groove of the stone pillar. Lin Tian carefully observed the groove on the stone pillar again and finally found a groove on one of the stone pillars that was extremely similar to the shape of the jade pendant. He carefully placed the jade pendant into the groove. With the embedding of the jade pendant, the runes on the stone pillar instantly lit up, and a mysterious force filled the entire cave. "Sure enough!" Lin Tian was delighted. He knew that this step had succeeded. However, as the runes lit up, the halo on the stone platform also began to change. The halo was no longer a simple faint light but gradually evolved into a complex rune chain, as if gradually unlocking some kind of seal. Lin Tian didn't continue to act but chose to wait and see. He knew that each step next was extremely crucial. Any mistake could lead to irreversible consequences. So, he decided to wait patiently to see exactly what changes this rune chain would undergo. Time passed slowly. The rune chain gradually covered the entire stone platform and finally condensed into a bright beam that shot straight towards the cave ceiling. With the activation of the beam, the atmosphere in the cave also became increasingly solemn, as if some powerful existence was gradually awakening. Although Lin Tian was full of anticipation in his heart, he couldn't help but feel a hint of unease. He knew that the power of this seal was extremely powerful, and the object it sealed must be an infinitely powerful treasure or some incredible force. At this moment, the beam suddenly retracted and instantly disappeared into the cave ceiling. What followed was a dull vibration. The entire stone platform began to slowly rise, as if pushed by some force, gradually revealing the secret beneath. Lin Tian stood in place, his gaze tightly the gradually rising stone platform. He knew that the lifting of the seal had entered the final stage, and he was about to uncover the true secret hidden in this ancient cave.
