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

After defeating the sand beast, Lin Yun and the others continued their arduous journey deeper into the desert, braving the scorching heat and wind. After walking for a while longer, they finally saw something unusual. Amidst the endless expanse of yellow sand, the outlines of some ruined buildings appeared faintly. These ancient, time-worn structures suggested they might be the forgotten ancient ruins they were seeking.

"Look, the ruins mentioned in the records should be in front of us. Everyone, be alert, there may be more dangers waiting for us inside." Lin Yun said, pointing to the front. When everyone heard this, a look of expectation and vigilance appeared on their tired faces, and they hurriedly quickened their pace and walked towards the ruins.

As they approached, they discovered the ruins were quite large, though most of the buildings had been eroded by wind and sand, leaving them in a dilapidated state. The carvings and runes on the walls were blurred, making it difficult to discern their original appearance. However, despite this, everyone could still sense the faint fluctuations of spiritual energy emanating from the ruins. Although the fluctuations were weak, they exuded an ancient and mysterious charm, making them increasingly certain that the "Hunyuan Holy Crystal" was likely hidden somewhere within the ruins.

Everyone cautiously entered the gate of the ruins. As soon as they entered, they heard a series of "clicking" sounds, as if some mechanism had been triggered. Then, rows of sharp stone spikes suddenly shot out from the ground, each coated with a layer of spiritual energy, and pierced towards them at an extremely fast speed.

"Be careful, there's a trap!" Lin Yun shouted, and everyone quickly cast their spiritual shields and used their physical skills to dodge. Stone spikes continued to emerge from the ground, some even ricocheting from cracks in the wall. The entire passage suddenly became perilous. Everyone dodged and rushed forward, trying to escape the stone-strewn area as quickly as possible.

After finally escaping the stone spike traps, the group barely had time to catch their breath before encountering a new one. Huge stone spheres appeared on the ceiling of the passage ahead, engraved with sinister runes and emitting strange spiritual energy fluctuations. They tumbled down towards the group, each one carrying immense force. If they were hit, the consequences would be disastrous.

"Everyone hide to the sides, don't get hit by the stone balls!" Lin Yun commanded everyone. Everyone used their spiritual power and jumped to the two sides of the passage, sticking tightly to the wall. The stone balls rolled over with a rumble, raising a cloud of dust. Everyone escaped the disaster, but they all knew in their hearts that the mechanisms in the ruins were probably linked one after another, and they had to be more careful.

After dodging several waves of traps, the group arrived at a spacious hall. The walls were covered in a variety of mysterious runes, which emitted a soft glow, illuminating the entire hall. The runes were extremely unique, some resembling ancient scripts, while others resembled abstract patterns. Standing in the hall, everyone felt as if they were in a mysterious spiritual world.

"These runes look unusual. Perhaps they're related to the whereabouts of the 'Hunyuan Holy Crystal.' Let's study them carefully," Lin Yun said, and everyone dispersed, examining the runes along the wall. Su Yao, with her unique understanding of spiritual runes, quickly discovered that these runes seemed to tell a story, or rather, a history about the ruins and the 'Hunyuan Holy Crystal.'

It turns out that this ruin was once the home of a powerful immortal cultivator from ancient times. This cultivator, driven by justice and aware of the dangers of the "World-Destroying Heretic Book," expended immense effort to locate five "Pure Origin Holy Crystals" and sealed them in different locations to counteract the evil power of the "World-Destroying Heretic Book." This ruin was one of the places he originally placed the Holy Crystals, but due to subsequent events, the traces of the Holy Crystals have become obscured, and the specific location of the Holy Crystals can only be found by solving the puzzle hidden by the runes.

After understanding the significance of the runes, everyone began to work together to crack the puzzles hidden in the runes. These puzzles were extremely complex, involving the understanding and application of many aspects of ancient immortal cultivation culture, spiritual power formations, and mysterious symbology.

Relying on his solid foundation in cultivating immortals and rich experience, Lin Yun deciphered some of the directional information implied by the runes; Su Yao, from the perspective of musical spiritual power, discovered that the arrangement order of the runes had a subtle connection with the rhythm changes of the music, and through this connection, he found some key clues; although Chen Yu and Zhao Gang were not as sharp as Lin Yun and Su Yao in interpreting runes, they also relied on careful observation and previous practical experience to point out some easily overlooked details, helping everyone to continuously improve their understanding of the puzzle.

After a long and difficult deduction and trial, everyone finally roughly figured out the direction the rune pointed to - under a stone platform in the center of the hall, there was probably an entrance to the passage where the "Hunyuan Holy Crystal" was located.

Everyone approached the stone platform in the center of the hall. After careful observation, they discovered that its surface was engraved with small runes that echoed those on the surrounding walls. These runes seemed to hold the key to unlocking the passage. Lin Yun, following the order he had learned from solving the puzzle, carefully injected his spiritual energy into the runes on the stone platform, muttering to himself, guiding the spiritual energy to flow through them.

Following Lin Yun's operation, the stone platform trembled slightly, and then a stone door slowly rose from under the stone platform. A stale and rotten wind mixed with a hint of danger blew out from the stone door, making everyone shiver.

"The passage is open. Everyone, be careful! Who knows what dangers await us inside?" Lin Yun warned. Everyone nodded, gripping their magic weapons tightly, and entered the stone gate one by one. The passage behind the stone gate was deep and dim. The walls were inlaid with a few faintly glowing spirit crystals, barely enough to illuminate the path. Everyone walked slowly along the passage, constantly alert to any movement around them.

They hadn't walked far when heavy footsteps echoed through the passage, as if something was approaching. Soon, a group of puppets, radiating an ancient spiritual energy, appeared. These puppets were different from those encountered in the mysterious evil's lair. They were taller and constructed from a mysterious, metallic material. Their eyes shone with a faint blue light, and they held ancient weapons in their hands. Their bodies were engraved with defensive runes, making them formidable.

"Another puppet! Everyone, be careful! These puppets don't seem simple!" Lin Yun shouted. Before he finished speaking, the puppets launched their attack. They brandished their weapons, wielding sharp spiritual blades that slashed at the crowd. Simultaneously, they flexibly utilized the power of the runes on their bodies, releasing spiritual shields to resist the crowd's counterattacks. The attack and defense appeared extremely orderly, clearly following a unique combat routine.

Lin Yun and the others quickly cast their spiritual shields to resist, while simultaneously launching a counterattack. Lin Yun unleashed the spiritual fusion technique from the Hunyuan Spiritual Method, fusing spiritual powers of different attributes into a powerful attack spell, which he blasted at the puppets. Su Yao played the Lingxi Jade Flute, the melody transforming into spiritual ripples that coordinated with the spiritual blades, attempting to disrupt the puppets' movements and spiritual shields. Chen Yu concealed his form, weaving between the puppets, searching for their weaknesses and waiting for an opportunity to launch a sneak attack with his spiritual dagger. Zhao Gang once again stood in front, blocking most of the frontal attacks with his shield, while finding the right opportunity to strike the puppets with it. The crowd and the puppets instantly engaged in a fierce melee, the sounds of battle echoing in the narrow passage, the spiritual light flickering continuously, and the battle was extremely stalemate.

During the fierce battle, everyone gradually discovered that although these puppets had strong defenses and orderly attacks, their actions seemed to have a certain pattern, and after each attack, there would be a short delay when the spiritual power flowed in their bodies, causing their movements to become stiff for a moment. Perhaps this was the flaw that could break through their defenses.

"Everyone, pay attention. The puppets will be stiff for a moment after attacking. That is their weakness. We must concentrate our strength to attack at that time!" Lin Yun shouted loudly. When everyone heard this, they were cheered up. They continued to resist the puppets' attacks while waiting for the right opportunity to come.

Finally, the puppets launched another attack, and at the moment the attack ended, as Lin Yun observed, their movements became stiff.

"Attack!" Lin Yun commanded, and everyone unleashed their remaining spiritual energy, blasting it towards the puppets' vital points—their chest spiritual cores. Suddenly, a dazzling array of spiritual energy shone, transforming into dazzling and powerful beams that fiercely impacted the puppets' spiritual cores. This attack proved effective. The spiritual cores in the chests of the struck puppets flickered, their movements becoming sluggish. Some puppets even stopped moving, collapsing to the ground in a heap of scrap metal, their fighting power gone.

Seeing this method was effective, the crowd pressed on, continuing to exploit the puppets' weaknesses and launch attacks. With their concerted efforts, the remaining puppets gradually gave in and were knocked to the ground one after another. The obstruction in the passage was cleared, and the crowd successfully broke through the puppets' defenses and continued to move deeper into the passage.

As they continued to go deeper, they felt the spiritual energy associated with the "Hunyuan Holy Crystal" grow stronger, knowing they were getting closer to their target. After walking a little further, they found themselves at the end of a secret room emitting a soft glow. The door was tightly closed, engraved with various defensive and sealing runes. The familiar spiritual energy fluctuations of the "Hunyuan Holy Crystal" emanated from within. Delighted, they quickened their pace to the door, but the complex runic restrictions on the door made them realize that opening it and obtaining the Holy Crystal would likely require considerable effort.

Lin Yun stepped forward and carefully observed the rune restriction on the door of the secret room. He found that this restriction combined a variety of ancient spiritual sealing techniques. It was extremely complex and exquisite. Once forcibly cracked, it would likely trigger a more powerful defense mechanism, and might even cause the entire ruins to collapse, burying everyone inside.

However, after previous training in deciphering rune puzzles, Lin Yun had a deeper understanding of these ancient restrictions. He closed his eyes, calmed his mind, and, relying on his spiritual perception, he gradually explored the spiritual power operating rules and key points of deciphering the rune restrictions.

While Lin Yun was studying the restriction, Su Yao, Chen Yu and Zhao Gang were not idle either. They were on guard around, guarding against possible emergencies, and also provided some reference opinions to Lin Yun from their own perspectives. After all, everyone has their own strengths on the road to cultivation, and maybe any detail could become the key to breaking the restriction.

After a long and meticulous process, Lin Yun finally found a way to break the restriction. He carefully injected spiritual energy into the runes in a specific order and manner, guiding the flow of the runes' spiritual energy. With a series of "clicks," the light of the runes on the secret room door gradually dimmed. The door slowly opened, and a dazzling light shot out from the secret room. Everyone hurriedly shielded their eyes with their hands. When the light faded slightly, they looked into the secret room. In the center of the room, a stone platform radiated pure spiritual energy. On the stone platform, a crystal crystal, seemingly containing endless spiritual power, lay quietly. It was the "Huanyuan Holy Crystal" that everyone had been searching for. Now, it was within reach, and everyone's faces showed excitement and relief.

Lin Yun, filled with excitement, slowly entered the secret room, approached the stone platform, and carefully picked up the "Hunyuan Holy Crystal." The moment he touched it, a warm and powerful spiritual energy flowed through his arm and throughout his body, making him feel comfortable and as if his spiritual power was nourished and enhanced.

"We finally found the first 'Hunyuan Holy Crystal', but there are still four waiting for us to find. However, this is also a good start." Lin Yun said, and everyone nodded. They knew that the road ahead was still long and full of difficulties and obstacles, but the results achieved at this moment also gave them great confidence and motivation.

After a brief rest in the secret chamber, the group left the ruins, carrying the "Hunyuan Holy Crystal." They knew that a mysterious evil force was also searching for the Holy Crystal. To prevent it from falling into their hands and to quickly destroy the "World-Destroying Evil Scripture," they had to expedite their search for the remaining four "Hunyuan Holy Crystals." Based on the clues they had previously obtained and their understanding of the entire world of immortal cultivation, they decided to head towards a mysterious valley in the west. It was said that there were ancient legends related to the "Hunyuan Holy Crystal" there, and perhaps the next Holy Crystal was hidden there.
