In the dim secret room, the figure that slowly emerged from the huge portal was like a demon crawling out from the depths of hell. The cold aura instantly spread, making the already oppressive atmosphere even heavier. The flickering candle flames on the walls, under the impact of this aura, danced frantically as if they would go out at any moment. Ye Chen's gaze was solemn, staring fixedly at that figure. This person was tall, surrounded by a layer of faint black mist, making it impossible to see his face clearly. But the terrifying aura emanating from him made Ye Chen understand that this would be an extremely powerful opponent. "Humph, being able to come here, you all have some skills." The mysterious person's voice was hoarse and cold, as if it came from the abyss of the netherworld, echoing in this narrow space and sending chills down one's spine. Ye Chen took a deep breath and stepped forward, "Who on earth are you? Why are you blocking us here?" The mysterious person sneered, "Ignorant child, there's no need to ask. Today, all of you will die here." As soon as the words were finished, the mysterious person suddenly raised his hands, and the air around seemed to freeze instantly. On his palms, black mist rapidly gathered like a vortex, more and more, denser and denser, until it formed a black energy ball as substantial as it could be. From this energy ball, intermittent heart-palpitating roars faintly emerged, as if containing the resentment of countless evil spirits. Ye Chen's heart suddenly contracted, and an unprecedented sense of crisis instantly welled up in his heart. "This power... is too terrifying. I'm afraid it's hard to resist." He inwardly exclaimed that it was bad, but there was not the slightest intention of retreat in his eyes. Instead, a strong fighting spirit was ignited. "No matter what, I can't just wait for death. Even if I die, I'll do my best!" The mysterious person's eyes flashed a cruel light, and he pushed his hands forward. The black energy ball instantly transformed into a surging black torrent, sweeping towards everyone with an overwhelming force. Wherever this black torrent passed, the space was distorted, emitting a teeth-chattering "creaking" sound. The stone slabs on the ground cracked one after another under its powerful pressure, and the crushed stones were卷入ed and instantly turned into dust. Ye Chen's face changed drastically and shouted loudly, "Everyone, be careful!" At the same time, he quickly mobilized the spiritual energy within his body and executed the defensive spiritual skill "Spiritual Light Shield". A layer of pale blue light instantly formed in front of everyone, attempting to resist this surging attack. However, that black energy was extremely powerful. The moment it collided with the Spiritual Light Shield, a dull sound was emitted. Ye Chen only felt a huge pressure coming, his arms trembled slightly, and cracks began to appear on the ground beneath his feet. "Break for me!" The mysterious person exerted more force again, and the black energy became even more turbulent. The black torrent was like a wild beast, frantically attacking the Spiritual Light Shield. With each impact, the light on the shield dimmed a little, and the cracks spread rapidly. Ye Chen gritted his teeth, his heart filled with anxiety: "No, this shield won't hold up for long like this. I must find the flaw of this attack." But at this moment, that black energy was like a overwhelming huge wave, making him almost unable to breathe. "Could it be that we're really going to die here today? No, I'm not reconciled! I still have unfulfilled missions and people to protect!" Ye Chen roared inwardly, desperately maintaining the Spiritual Light Shield. Just when the Spiritual Light Shield was about to break, a look of determination flashed in Ye Chen's eyes, "Everyone, attack together!" Upon hearing this, everyone exerted their strongest spiritual skills. For a moment, various rays of light interwove together, countering the black energy. The light reflected on the walls, forming strange shadows, as if a group of demons were dancing wildly. With the joint efforts of everyone, they finally managed to barely resist this round of attack from the mysterious person. The mysterious person seemed surprised that everyone could resist and was slightly stunned. Then he shouted angrily, "You have some ability, but this is just the beginning!" The mysterious person then joined his hands to form seals and muttered incantations. In an instant, the temperature around dropped sharply, and a cold air spread. The originally damp ground quickly condensed a thick layer of frost, and everyone's movements became sluggish. The mysterious person seized the opportunity to launch another attack. A huge ice pillar came crashing towards everyone. The ice pillar sliced through the air, emitting a sharp whistling sound, terrifying to the extreme. Ye Chen's figure flashed to avoid the ice pillar and simultaneously swung his sword at the mysterious person. The mysterious person was not flustered and casually waved his sleeve, dissolving Ye Chen's attack. Ye Chen was secretly astonished in his heart. This person's strength far exceeded his imagination. But he did not retreat but fought even more bravely. Ye Chen executed his renowned spiritual skill "Blazing Sun Sword Technique", and flames rose above the sword body, forming a sharp contrast with the surrounding cold air. His figure was like lightning, attacking the mysterious person. The mysterious person snorted coldly, "Trifling skills!" Then, he stretched out a palm, and a black vortex appeared in the palm, actually absorbing all of Ye Chen's flames. Ye Chen was already injured in many places during the fierce battle, and his clothes were stained with blood. After everyone repelled the mysterious person, they hurriedly gathered around. "Ye Chen, how are you?" A companion asked anxiously. Ye Chen endured the pain, his face pale, and tremblingly took out a precious bottle of healing pills from his bosom. His hand was a little unsteady, and it was very difficult for him to open the bottle cap. "I can still hold on. Take this pill first." Ye Chen said through gritted teeth. He poured the pill into his mouth. As soon as the pill entered his mouth, it instantly turned into a warm and rich medicinal liquid. The liquid flowed down his throat like a warm current, rapidly spreading within his body. Ye Chen could feel that the medicinal power first rushed to the chest where he was injured the most. The wound there seemed to be gently stroked by a pair of gentle hands, and the pain gradually lessened. The damaged meridians were nourished by the medicinal power, reconnecting bit by bit, and the circulation of spiritual energy gradually became smooth. However, the atmosphere in the secret room was still tense. Stones from the ceiling dropped from time to time, making "thudding" sounds, as if it was the countdown to death. Then, the medicinal power flowed towards his limbs. The skin that was bruised due to the attack by the mysterious person began to return to its normal color, and the soreness of the muscles gradually subsided. Ye Chen could clearly feel his strength returning bit by bit. After a while, Ye Chen finally let out a long breath and slowly opened his eyes. His eyes regained their luster. Although his injuries were not completely healed, he had regained quite a bit of strength. "Everyone be careful. This mysterious person might come back." Ye Chen said. His voice was still a little weak but had become more determined. Everyone nodded, getting ready to face the enemy again.
