I was reborn as a young master in an invincible family of immortals

Everyone hurried toward the mysterious light, but the closer they got, the more eerie the surroundings became. The mist, which had been thinning at first, began to thicken again, as if it had come to life, entwining itself with the group in strands. Every time it touched them, they felt as if a layer of cold mucus coated their bodies, and their spiritual energy became sluggish.

Furthermore, the ground beneath their feet became uneven and bumpy, with sharp stone spikes occasionally protruding from the ground, piercing their legs at great speed. As they dodged the attacks of the stone spikes while simultaneously clearing away the encroaching fog, their progress suddenly slowed considerably, and everyone's face was filled with solemnity.

As they trudged forward, various visions gradually emerged from the mist. They first witnessed regretful scenes from their pasts, the grief of loved ones' deaths, the despair of failure in their cultivation. These scenes were so real that they drew them in, profoundly affecting their emotions and causing signs of disturbance in their spiritual energy.

"Everyone, don't be fooled by these illusions. Keep your mind focused. These are all illusions created by the fog!" Lin Yun reminded loudly. However, despite this, the attraction of the illusion was too great. Everyone could only grit their teeth, force their spiritual power to move, and perform various concentration and calming techniques to try to drive these disturbing illusions out of their minds. But this was easier said than done. For a moment, everyone was caught in the dilemma of struggling with the illusions.

After a long struggle, everyone finally managed to free themselves from the illusion through sheer force of will. However, before they could recover, a massive vortex of spiritual energy suddenly appeared on the ground ahead. Strange runes shone within it, rapidly spinning and releasing a powerful suction force that attempted to pull everyone towards its center.

"Watch your step, this is another trap!" Lin Yun shouted, and everyone hurriedly stopped, but the suction was too strong. Even though everyone tried their best to resist, their bodies still moved slowly towards the whirlpool uncontrollably, and the situation became very critical.

"Everyone, use your spiritual power together and push in the opposite direction to see if you can break free from this suction!" Lin Yun commanded everyone. After that, he took the lead in gathering the spiritual power to his feet, and stepped hard in the direction away from the vortex. At the same time, he waved the spiritual staff in his hand and sent out a reverse spiritual power impact, trying to offset the suction of the vortex.

Others followed suit. Su Yao played the Lingxi Jade Flute, and the melody transformed into spiritual power ripples that crashed into the source of the vortex's suction, interfering with its spiritual power circulation; Chen Yu hid his body and searched along the edge of the vortex for any weak points that could be destroyed; Zhao Gang stood firmly on his horse, using his shield to support the ground, resisting the suction with all his strength, and at the same time providing a relatively stable support point for everyone. Everyone worked together to stalemate with the powerful vortex suction.

With everyone's hard work, Chen Yu finally discovered that the source of the suction of this spiritual power vortex lies in a black spiritual crystal at the bottom of the vortex. The spiritual crystal continuously releases spiritual power to maintain the operation of the entire vortex.

"Brother Lin Yun, I found the key. There is a black spirit crystal at the bottom of the vortex. Destroying it should be able to stop the vortex!" Chen Yu shouted loudly. Upon hearing this, Lin Yun immediately directed everyone to gather the remaining spiritual power, turning it into a sharp spiritual power beam, and blasted it towards the black spirit crystal that Chen Yu pointed at.

With a roar, the spiritual power beam hit the black spiritual crystal accurately. The spiritual crystal shattered instantly under the powerful attack. The spiritual power vortex seemed to have lost power and slowly stopped rotating. The suction disappeared. Everyone breathed a sigh of relief, wiped the sweat from their foreheads, and continued to move forward in the direction of the mysterious light. At this moment, they were one step closer to the target, but their vigilance was not reduced at all.

After walking a little further, they finally passed through the fog and arrived at the source of the light. An ancient and mysterious hall appeared before them, its walls engraved with obscure runes and patterns, emitting a faint, dim glow. The door was tightly closed, and inlaid with several softly glowing spirit crystals. This was the source of the light, and the spiritual power fluctuations of the "Hunyuan Holy Crystal" were emanating from within the hall. Everyone was delighted, believing that the final Holy Crystal must be within this hall.

"We've finally found it, but this hall is definitely still guarded by numerous restrictions. Everyone, be careful and prepare to go in and take a look," Lin Yun said. Everyone nodded and, after preparing for battle, Lin Yun stepped forward and attempted to slowly inject his spiritual energy into the spiritual crystal on the gate to see if he could open it. As the spiritual energy was injected, the light of the spiritual crystal on the door gradually brightened. A series of "clicking" sounds were heard, and the door slowly opened, releasing an even richer, mysterious spiritual energy. With a mixture of nervous anticipation, everyone stepped into the hall.

After entering the hall, everyone was shocked by the scene inside. The hall was extremely spacious, with many ancient stone platforms placed around it. On the stone platforms were placed various rare treasures and magic weapons, each emitting a dazzling light. However, everyone's attention was instantly drawn to the stone platform in the center of the hall.

On that stone platform sat a crystal radiating pure and vast spiritual energy. Its translucent crystal seemed to contain endless spiritual power, and it was precisely the final "Hunyuan Saint Crystal" they had been searching for. However, surrounding the platform was a layer of transparent spiritual energy restriction, with shimmering runes on it, clearly a final barrier erected to protect the Saint Crystal. Everyone knew that to obtain the Saint Crystal, they must first break through this restriction.

Everyone gathered around the stone platform, carefully examining the spiritual power restriction. Lin Yun discovered that the runes were extremely complex, incorporating spiritual energy of various attributes and forming a tight loop system. Triggering the wrong rune would not only fail to break the restriction, but could also trigger an even more powerful defense mechanism, potentially affecting the entire hall and plunging everyone into a desperate situation.

Su Yao also frowned and said, "This restriction seems to contain a special soul power, as if it can sense our intentions. It may not be so easy to break it." After hearing this, everyone fell into deep thought, thinking about where to start to break this tricky spiritual restriction.

Just when everyone was racking their brains and had no clue, Chen Yu suddenly remembered that he had seen a record of a similar restriction containing soul power in an ancient relic. It mentioned that if one could find a spiritual object that resonated with this soul power and use it as a guide, perhaps they could disrupt the spiritual power circulation of the restriction and find an opportunity to break it.

Upon hearing this, everyone thought it was a viable solution and began searching the hall, hoping to find such a spiritual object. After a careful search, Zhao Gang found a jade pendant in a corner, emitting a faint glow. The jade pendant was warm to the touch, and it had faint soul runes on it, similar to the soul power fluctuations on the spiritual power restriction. Everyone was delighted, feeling hopeful, and hurriedly took the jade pendant to the stone platform, ready to use it to break the restriction.

Lin Yun carefully held the jade pendant, bringing it close to the spiritual power barrier. He slowly released a trace of spiritual energy, directing the soul power within the jade pendant to resonate with the soul power within the barrier. At first, the barrier trembled only slightly, but as Lin Yun continuously adjusted the output and guidance of his spiritual energy, the resonance between the jade pendant and the barrier grew stronger, and the runes on the barrier began to flicker, showing signs of disorder.

"Everyone, act now! Follow the sequence we agreed upon and inject your spiritual energy into the key points of the restriction!" Lin Yun shouted. Hearing this, everyone gathered their spiritual energy and accurately injected it into the corresponding points of the restriction. With everyone's concerted efforts, the spiritual energy restriction finally gave way. With a series of crackling sounds, it shattered with a bang, dissipating into tiny specks of light in the air. Finally, the final "Hunyuan Saint Crystal" appeared before everyone's eyes, unimpeded.

Lin Yun walked forward and picked up the holy crystal excitedly. At this moment, the five "Hunyuan Holy Crystals" had been gathered. Everyone's faces were filled with joy and relief. They had gone through countless hardships and obstacles, and now they had finally achieved their goal. But next, they had to face the mysterious evil force and destroy the "World-Destroying Evil Book".
