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

Lin Yun and the others slowly advanced along the secret passage. It was deep and narrow, its walls inlaid with shimmering gemstones, illuminating their path. The walls on either side of the passage were densely engraved with mysterious runes, which shimmered faintly, as if telling ancient stories and exuding an elusive, mysterious power.

Su Yao approached the wall curiously, carefully observing the runes, and whispered: "These runes look extremely ancient. I can feel that they contain deep spiritual power, but the specific meaning is difficult to interpret. Maybe there are some important clues or restrictions hidden in them."

Lin Yun nodded and said, "Everyone, be careful and don't trigger any mechanisms. Chen Yu, keep an eye out for any unusual spiritual energy fluctuations up ahead. If you find anything amiss, notify everyone immediately."

Chen Yu responded, casting his spiritual perception technique and cautiously walking in front, constantly alert to the surrounding movements. Everyone followed him, slowing down their pace, observing the runes as they walked deeper into the passage. The further they went, the stronger the mysterious spiritual energy fluctuations became, as if drawing them deeper.

As they walked, a dazzling light suddenly appeared in front of them. The light seemed to contain endless mysteries, making people want to get closer to explore. Everyone quickened their pace and after passing through the light, they found themselves in a huge and mysterious space.

Numerous spheres of light, emitting a variety of colors, hovered within this space. Some were as large as a fist, while others were several feet in diameter. They hovered silently in the air, illuminating the entire space with a dazzling array of colors. In the center of the space stood a massive stone platform, upon which rested a quaint treasure box. Its surface was engraved with intricate patterns, emitting a powerful and sacred aura that made it clear at first glance that it was something extraordinary.

"What's in the treasure box? I feel like it must be something extraordinary." Zhao Gang said with his eyes wide open and a look of curiosity on his face.

Lin Yun was also attracted by the treasure box, but he remained cautious and said, "Don't rush to get close. This space is so mysterious. There might be some kind of protective mechanism around it. Let's observe it first."

Everyone followed his instructions, dispersed, and slowly moved around the edge of the space, trying to find possible dangers or clues so that they could safely obtain the treasure box on the stone platform.

Chen Yu used his spiritual perception to carefully explore this mysterious space. He discovered that the light balls suspended in the air seemed calm, but in fact contained powerful spiritual fluctuations. There seemed to be a subtle connection between them. If someone approached rashly, it would probably trigger a chain reaction.

"Senior Brother Lin Yun, there's something wrong with these light balls. They seem to form a hidden spiritual power formation. If you accidentally touch them, it might cause danger." Chen Yu frowned and reported to Lin Yun.

After hearing this, Lin Yun's expression grew serious. He said, "It seems that getting the treasure box won't be that easy. We must first understand the principles of this spiritual power formation and find a way to pass through it safely."

So, everyone gathered together to discuss countermeasures. Wang Lin, relying on his knowledge of mechanical restrictions and spiritual power formations, proposed an idea: "I think we can try to start with the spiritual power fluctuation frequency of these light balls and find the pattern of their operation. Then, according to this pattern, we can find a route with relatively weak spiritual power. Perhaps we can avoid danger and approach the stone platform."

Everyone thought it made sense, so they began to carefully observe the spiritual power fluctuations of the light balls, trying to find the pattern. However, this was not an easy task. The spiritual power fluctuations of those light balls were complex and changeable, and it required extremely high patience and keen spiritual power perception to discover anything.

After long observations and repeated spiritual power detection, Wang Lin finally discovered some patterns in the spiritual power fluctuations of the light balls. She exclaimed in surprise, "I've discovered that the spiritual power fluctuations of these light balls cycle according to the changes in the directions of the Nine Palaces and Eight Trigrams. And every so often, the spiritual power of several key light balls weakens, forming a short, safe passage. If we can seize this opportunity and quickly pass through the passage, we should be able to reach the stone platform."

When everyone heard this, hope ignited in their hearts, but they also understood that there were great risks involved. After all, if they made a mistake, they might trigger the spiritual power formation and fall into unknown danger.

"I'll try it first, and you guys support me from behind. If anything happens to me, use your spiritual power to pull me back immediately." Lin Yun volunteered. He took a deep breath, waited for the right moment, and when the short safe passage appeared, he flashed and rushed towards the stone platform.

The other team members nervously watched Lin Yun's every move, their spiritual energy gathered in their palms, ready to help at any moment. Lin Yun's speed was extremely fast. At the moment the passage was about to close, he successfully crossed most of the distance and was about to reach the stone platform. At this moment, the spiritual energy fluctuations of one of the light balls suddenly became abnormal, and a powerful spiritual energy beam was fired towards Lin Yun's position.

The spiritual beam was so fast that Lin Yun couldn't dodge it. He could only grit his teeth and mobilize his spiritual energy, unleashing his defensive techniques to block it. The beam struck his spiritual shield with a loud bang, and the powerful impact sent Lin Yun flying backwards, a trace of blood oozing from his mouth.

"Senior Brother Lin Yun!" Everyone exclaimed, and Su Yao hurriedly played the Lingxi Jade Flute. The fluctuations of spiritual power turned into a gentle force, flying towards Lin Yun, slowing down his backward flight speed. Chen Yu, Wang Lin and Zhao Gang also took action at the same time, throwing out several spiritual power ropes, which tightly wrapped around Lin Yun and pulled him back.

"I'm fine, I was just careless. This spiritual power formation is more complicated and changeable than I imagined." Lin Yun wiped the blood from the corner of his mouth, his eyes full of unwillingness. He looked at the treasure box in the direction of the stone platform, and his determination to get it became more and more firm.

After this series of twists and turns, everyone realized they couldn't just blindly try anymore. They needed to be more precise with their timing and develop a more comprehensive plan. So, everyone gathered together again, carefully analyzing the issues that had arisen, and considering the new changes in the spiritual energy fluctuations of the light ball, they recalculated a more reliable route.

After careful calculation and preparation, Lin Yun once again seized the opportunity and rushed towards the stone platform. This time, he moved more cautiously, each step precisely stepping on the weak points of spiritual energy fluctuations, cleverly avoiding the dangerous light balls that could erupt at any time.

The other team members watched nervously from behind, sweat in their hands, ready to provide support at any time. Fortunately, Lin Yun did not encounter any accidents this time. He successfully passed through the numerous obstacles and arrived in front of the stone platform.

Lin Yun took a deep breath, carefully reached out, and picked up the treasure box that exuded a powerful aura. The moment he touched it, he could feel the vast and mysterious power contained within the treasure box, as if there were endless secrets waiting for him to uncover.

"We got it!" Lin Yun shouted to his teammates behind him. Everyone cheered immediately, their faces full of excitement and joy. After going through so many hardships and dangers, they finally succeeded in obtaining this mysterious treasure box.

Everyone gathered around, looking curiously at the treasure box in Lin Yun's hand, eager to know what treasure was inside. Lin Yun tried to find the opening mechanism of the treasure box. After groping for a while, he found a slightly concave area on the treasure box, shaped like a spirit pearl.

He remembered the spirit beads he had collected in the building, so he took one from his storage device and placed it in the recess. With a soft click, the treasure box slowly opened, and a soft light emanated from it. After the light dissipated, everyone saw two objects inside the treasure box—an ancient book emitting a golden glow, and a crystal-clear pill with stars flowing inside it.

"These ancient books and elixirs don't look like ordinary items. Maybe they contain great opportunities." Su Yao exclaimed.

Lin Yun gently picked up the ancient book and flipped it open. He discovered that it contained a profound technique for cultivating immortality. This technique not only involved the cultivation of spiritual power but also was closely related to the understanding of the laws of heaven and earth. If successfully cultivated, one's strength would surely achieve a qualitative leap. The elixir exuded a rich spiritual aroma. Just one sniff of it made one feel as if the spiritual power in one's body was invigorated. It was clearly a peerless elixir that would greatly aid in improving cultivation.

Faced with such precious treasures, everyone had no intention of fighting for them. Instead, they began to discuss how to distribute them so that they could maximize their value and be most beneficial to the sect.

Lin Yun looked at everyone and said, "This ancient manual of cultivation techniques is profound and difficult to understand. After we bring it back to the sect, we need to study it together. If we can integrate it into our sect's cultivation system, it will be of great help to the sect's disciples. As for this pill, I think it can be given to the elders in the sect who are about to break through the bottleneck of their cultivation. It will help them improve their strength and better protect the sect."

Everyone nodded in agreement. They knew that they came to the Fairy Island to seek opportunities for the sect. The most important thing was that these treasures could bring greater development to the sect.

"Then it's settled. Let's put the treasures away properly first, and then continue exploring this fairy island to see if there are any other good things we have missed." Su Yao said, and everyone carefully put the ancient books and elixirs into the storage magic weapon, and then began to search other corners of this mysterious space, hoping to have new gains.

After a thorough search, they discovered another passageway in a corner of the space, leading downward. The passageway also emanated mysterious spiritual energy fluctuations, but compared to the previous passage, this one seemed deeper and more ancient, as if it led to a more hidden part of the fairy island.

"There should be something down there. Let's go down and take a look," Lin Yun said, leading the way towards the passage. The others followed without hesitation, and they slowly descended the passage, their hearts filled with curiosity about the unknown and a faint sense of anticipation, wondering what kind of immortal fate would await them at the end of this passage.

After walking along the passage for a long time, the mysterious atmosphere became stronger and stronger, and the surrounding temperature gradually dropped. Some crystal clear ice crystals began to appear on the walls of the passage, sparkling beautifully in the dim light.

Finally, the end of the passage appeared in front of everyone. It was a huge cave covered with ice and snow. The cave was filled with white mist. Some vague figures could be seen swaying in the mist. An unknown and powerful force emanated from the depths of the cave, which made people feel awe.

"It feels so mysterious here. Everyone, be careful and don't act rashly."
