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

The joy of holding five Primordial Saint Crystals had barely faded, yet everyone knew the task ahead would be even more arduous. Lin Yun carefully stored the Saint Crystals away, looking at everyone solemnly. "Although we've gathered all the Saint Crystals now, that mysterious evil force will certainly not give up. They've undoubtedly learned of our plans and will undoubtedly create numerous obstacles on our path to destroying the 'World-Destroying Heretical Scripture.' We must be extremely vigilant."

Everyone nodded, each checking their own magic weapons, adjusting their own states, and optimizing their spiritual energy. Su Yao gently stroked the Lingxi Jade Flute, her gaze determined; Chen Yu concealed his form, testing his agility; Zhao Gang patted his shield vigorously, ready to strike. With everything ready, they followed the clues they had received and headed for the rumored hiding place of the "World-Destroying Evil Book"—the "Abyss Demon Cave."

They sped through the air, but before they had gone far, the sky around them suddenly darkened. From the thick clouds, black spiritual lightning bolts struck them. At the same time, a group of black-robed figures surrounded them from all directions. The evil aura from these black-robed figures was even stronger than those they had encountered before. They were clearly the elite of the mysterious evil forces.

"Hmph, if you want to destroy the 'World-Destroying Evil Book,' you'll have to get past us first!" the leading black-robed figure shouted. With a wave of his hand, the black-robed group immediately launched their attack. Various evil spiritual energies converged into attack spells that descended upon the group in a torrent of force. Some spiritual blasts transformed into ferocious ghostly faces, while others bound them like black chains. The onslaught was incredibly ferocious.

Lin Yun and others hurriedly stopped and displayed their strongest spiritual defense. Lin Yun waved his spiritual staff and muttered something. A spiritual light curtain condensed by the "Hunyuan Spiritual Method" rose up instantly, protecting everyone in it; Su Yao played the Lingxi Jade Flute, and the spiritual ripples transformed by the music merged with the light curtain to enhance its defense. At the same time, it hit the black-robed man's attack in the opposite direction, trying to offset some of the power; Chen Yu hid his body, shuttled among the black-robed men, looking for an opportunity to launch a surprise attack; Zhao Gang held a shield and stood in front of the light curtain to resist the powerful attacks coming from the front. A fierce air battle began.

The black-robed men's attacks continued in waves, the spiritual energy curtain flickering and teetering under the constant impact. Although Lin Yun and the others resisted with all their might, the other side was outnumbered and coordinated well, and for a moment, they were caught in a bitter battle.

While maintaining the light curtain, Lin Yun performed the art of spiritual power fusion, blasting spiritual power beams towards the area where the black-robed men were densely packed, but the black-robed men dispersed flexibly and avoided many attacks; Su Yao changed the rhythm of her playing, trying to use the power of music to interfere with the black-robed men's attack rhythm and positioning, but the effect was not ideal. The black-robed men seemed to have undergone special training and had a strong resistance to musical interference; although Chen Yu successfully sneak attacked several black-robed men, the other party quickly reacted and surrounded him, making it difficult for him to escape; Zhao Gang was under tremendous pressure. Every time he resisted, his arms were numb and his spiritual power was consumed very quickly. The situation was very unfavorable for everyone.

In the fierce battle, Lin Yun, despite the fatigue from excessive spiritual energy consumption, carefully observed the black-robed men's attack patterns and positioning. He discovered that when these black-robed men cast combined attack spells, several of the black-robed men responsible for connecting the spiritual energy remained relatively fixed in position, and there was occasionally a subtle delay in the flow of spiritual energy between them. Perhaps this was the flaw that could break their attack rhythm and turn the tide of the battle.

"Everyone, pay attention. In the black-robed man's combined attack spell, there is a delay in the spiritual power connection between those guys in fixed positions. We must concentrate our forces to attack there and disrupt their rhythm!" Lin Yun shouted loudly. When everyone heard it, they were cheered up. Although they were exhausted at the moment, they still forced themselves to cheer up and wait for the right opportunity to come.

Finally, the black-robed men unleashed another combined attack. Just as the crucial black-robed men's spiritual energy was delayed, Lin Yun seized the opportunity and shouted, "Attack!" Everyone unleashed their energy in unison, blasting their remaining spiritual energy towards the flaw. A brilliant beam of spiritual energy shot towards the target like a sharp sword, striking the black-robed men squarely.

There was a scream, and those black-robed men were hit by the spiritual light beam. Their bodies flew backwards, blood spurting out of their mouths. The originally powerful combined attack spell was instantly disrupted, and the black-robed men were thrown into chaos, and there was a brief panic for a while.

"Great opportunity, let's seize the opportunity!" Lin Yun shouted upon seeing this. Everyone seized this rare opportunity and immediately launched a counterattack. The dagger in his hand swung outwards, and several more people in black robes were injured and fell to the ground. Zhao Gang raised his shield and rushed towards the black-robed people, hitting the approaching enemies with his shield, knocking them to the ground. The situation of being passively beaten was instantly reversed. The black-robed people could not withstand the fierce attacks of the crowd, and gradually began to retreat, and a gap appeared in the encirclement.

Seeing that the man in black robes was about to retreat, Lin Yun knew that it was not appropriate to fight at this moment. After all, their goal was to rush to the "Dark Abyss Demon Cave" as soon as possible to destroy the "World-Destroying Evil Book", rather than to stay here with the man in black robes for too long.

"Everyone, stop chasing them. Let's go quickly. They will definitely come again!" Lin Yun shouted. Everyone understood and immediately used their skills to continue on their way towards the "Dark Abyss Demon Cave". However, they all knew very well that this was just the beginning. What was waiting for them later would definitely be more dangerous obstacles.

After a rapid flight, they finally arrived at the area where the "Abyss Demon Cave" was located. Before they even got close, a strong, sinister aura filled them. It felt tangible, making breathing difficult. The surrounding area was rendered pitch black. Faint, eerie roars could be heard emanating from the depths of the cave, as if countless demons were howling within. The mere presence of this aura was enough to chill one to the bone.

"The evil forces in this place are very strong. Everyone, be careful and don't let this aura affect your mind," Lin Yun warned. Everyone hurriedly channeled their spiritual energy, protecting their minds as they cautiously approached the entrance to the demon cave. The entrance to the demon cave was a massive black hole, engraved with various evil runes. These runes glowed with eerie light, as if warning everyone not to approach. However, they shouldered the mission of saving the world of immortal cultivation, so how could they retreat? They resolutely walked into the cave, step by step.

As soon as they entered the demonic cave, they felt their feet sink, as if they were trapped in some kind of slime, and their movements became extremely slow. Then, rows of sharp spiritual bone spurs shot out from the cave wall. These bone spurs were imbued with evil power. Once pierced, the evil power would penetrate the body through the wound, corroding the spiritual power, making the situation extremely critical.

"Beware of traps!" Lin Yun shouted, and everyone hurriedly used their spiritual power to try to break free from the slime beneath their feet, while simultaneously erecting spiritual shields to block the incoming spiritual bone spurs. After finally freeing themselves from the slime, before anyone could even catch their breath, massive spiritual vortexes appeared on the ground ahead. Within these vortexes flashed ferocious ghostly faces, baring their fangs and claws as they unleashed a powerful suction force towards the group, seemingly intent on drawing them all in. Everyone was plunged into a new crisis, forced to brace themselves once again to deal with the continuous stream of traps.

Facing these spiritual power vortexes, Lin Yun observed them calmly and found that the spiritual power circulation of these vortexes seemed to have some connection with the evil runes on the cave wall. As long as the spiritual power supply of the runes was destroyed, perhaps the vortexes could be stopped.

"Everyone, block the vortex's suction first. I'll destroy the runes on the cave wall!" Lin Yun said, unleashing his agility to charge towards the cave wall. As everyone worked together to resist the vortex's suction, Lin Yun arrived at the cave wall, wielded his staff, and unleashed a spiritual attack, blasting the flickering evil runes. As the runes were destroyed, the spiritual vortex gradually lost momentum, slowly ceasing its rotation, and the suction vanished. Only then could everyone continue their journey deeper into the cave. However, similar traps appeared along the way, forcing everyone to break them as they struggled towards their goal. Each step was an extremely difficult one.

After navigating countless traps and difficult obstacles, the group finally reached the depths of the demonic cave. Atop a massive stone platform sat a tome emitting a thick, sinister aura. Its cover was inscribed with twisted runes, revealing the much-sought-after "Hellenistic Book of Destruction." However, surrounding the platform lay a powerful barrier of evil spiritual energy, pulsing with black spiritual light, forming an impenetrable barrier that protected the "Hellenistic Book of Destruction." To destroy it, the group must first break through this barrier, a feat no easy task. Standing not far from the platform, the group pondered their next move.

Everyone gathered together, frowning as they gazed at the powerful evil spiritual barrier. Lin Yun spoke first, "The evil power of this barrier is too strong, and its structure is extremely complex. We can't act rashly. Once its defense mechanism is triggered, the consequences will be disastrous. Let's first think of a way to break it."

Su Yao looked at the restriction and said thoughtfully: "Since this restriction relies on evil spiritual power to maintain its operation, we may be able to try to neutralize it with the pure spiritual power of the Saint Crystal, disrupt its spiritual power structure, and then find a flaw to break through."

After hearing this, everyone felt that it made some sense, but they were also worried that this would lead to other unknown dangers. However, there was no better way at the moment, so they could only decide to try this idea first. So everyone carefully took out the "Hunyuan Holy Crystal", ready to use the power of the holy crystal to break the restriction in front of them that concerned the fate of the world of immortal cultivation, but they did not know what the consequences of doing so would be.
