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

Lin Yun took a deep breath, suppressed the slight uneasiness in his heart, and slowly placed his hand on the treasure box in front of him. He could clearly feel the slight coolness coming from the treasure box, as well as the faint fluctuations of spiritual energy, as if the treasure inside was eager to break free from the seal.

The other team members also gathered around, staring closely at Lin Yun's movements, their eyes full of anticipation and nervousness.

Lin Yun gently exerted force, trying to open the treasure box. However, the box remained motionless, as if sealed by a powerful force. He was far from being able to open it with his current strength.

"The seal of this treasure box is so strong." Lin Yun said with a frown.

"Will it require some special method or formula to open it?" Lin Xiao guessed from the side.

Lin Yun's heart stirred, and he once again carefully examined the runes engraved on the treasure box. The runes were complex and mysterious, each stroke seeming to hold a profound meaning. He closed his eyes and diligently searched his mind for the ancient texts he had read, hoping to find a clue to unlocking the seal of the treasure box.

Suddenly, he remembered a book on ancient sealing techniques, which mentioned some methods of interpreting runes. Lin Yun hurriedly followed the method he remembered, slowly injecting spiritual power into the runes on the treasure box, while muttering a difficult-to-understand formula.

With the infusion of spiritual power and the recitation of the mantra, the runes on the treasure box gradually lit up, and the light became brighter and brighter, like bright stars twinkling on the treasure box.

"There's a response!" a team member shouted excitedly.

Just as everyone was filled with anticipation, the treasure box suddenly vibrated violently. A powerful force gushed out from the box, violently ejecting Lin Yun. Lin Yun's body was unstable and he took a few steps backward. If the team members behind him hadn't supported him in time, he would have fallen to the ground.

"What's going on?" Everyone was shocked.

Before they could react, the treasure box began to vibrate more violently, stirring the air around it into chaos. Then, rays of colorful light shot out from the treasure box, shooting towards the crowd like sharp arrows.

"Be careful!" Lin Yun shouted and hurriedly cast a spiritual shield to cover himself and the team members around him.

The other team members also reacted and used their own defensive measures to resist the colorful light.

The light kept hitting the shield, making roaring sounds. The shield rippled under the impact of the light and was on the verge of collapse.

"Why would this treasure box suddenly attack us? Is it because we opened it incorrectly?" Lin Xiao said anxiously.

Lin Yun maintained his shield while thinking about countermeasures. He guessed that perhaps they had triggered some kind of defense mechanism of the treasure box, which led to the current situation.

Just as everyone was struggling to hold up the shield, the treasure box's attack suddenly stopped, the light gradually dissipated, the treasure box stopped vibrating, and calm was restored.

Everyone breathed a sigh of relief, but the doubts in their hearts grew even more.

"What should we do now? Should we continue trying to open it?" asked a team member.

Lin Yun looked at the treasure box, a flicker of determination in his eyes. He knew they had come this far and couldn't give up just because of this setback. Furthermore, the treasures within the box could potentially be of great assistance to their path to immortality, and perhaps even hold clues to unlocking the mystery of rebirth.

"Keep trying, everyone be careful, we'll try a different method this time," said Lin Yun.

Everyone gathered around the treasure box once again, and Lin Yun carefully studied the runes on it. He realized that his previous method of injecting spiritual energy might have been a bit too hasty, causing it to trigger the treasure box's defenses. This time, he decided to proceed more cautiously.

Lin Yun first gently touched the rune with his spiritual power, feeling the fluctuations of the rune's spiritual power, trying to find the pattern within. Then, according to the pattern he had figured out, he injected spiritual power bit by bit, while closely monitoring the treasure box's reaction.

Under Lin Yun's control, the treasure box responded again. The runes slowly lit up, but this time the light was much softer, lacking the previous violent glow.

As spiritual power continued to be injected, a tiny crack appeared on the treasure box. The crack gradually expanded, and finally, accompanied by a slight "click", the treasure box slowly opened.

A strong spiritual energy rushed over them, and everyone felt refreshed. They couldn't wait to look inside the treasure box, only to see an ancient book with a simple and ancient atmosphere. The paper of the ancient book was a little yellowed, but the handwriting on it was still clearly visible.

"It's an ancient book, maybe it contains some powerful martial arts!" a team member said excitedly.

Lin Yun carefully took the ancient book out of the treasure box and gently opened the first page. He saw a few big words written on it - "Chaos Spirit Secret".

"The Chaos Spirit Art? I have never heard of this technique. I don't know what's so wonderful about it." Lin Xiao said doubtfully.

Lin Yun was also filled with curiosity. He continued to read and found that the cultivation method described in this manual was completely different from what he had previously known. It seemed to contain a kind of chaotic power that could make the practitioner's spiritual power more powerful and pure, and it could continuously open up new meridians during the practice, increasing the speed of cultivation.

After hearing Lin Yun's introduction, everyone was surprised and delighted. They knew that if they could practice this technique, it would be of great help in improving their strength.

"It seems that this trip to the ruins has been quite fruitful, but there are several other treasure boxes here. Let's continue to open them and take a look." Lin Yun said.

Everyone nodded, and they turned their gaze to the remaining treasure boxes on the stone platform, their eyes full of anticipation, ready to continue exploring for the precious treasures that might be hidden in them.

But at this moment, a low buzzing sound suddenly sounded in the hall. The sound seemed to come from deep underground, carrying an ancient and mysterious aura, which made everyone's heart tighten.

"What's going on again? Why are there always problems in these ruins?" complained a team member, his face full of worry.

Everyone became alert and quickly scanned the hall, trying to find the source of the sound.

The previously tranquil hall floor began to ripple slightly, as if something was surging beneath the surface. Then, rays of light shone through the cracks in the ground, gradually converging into a massive array of light.

The light array flashed with a strange light, and there seemed to be some vague images floating in the light, but before everyone could see clearly, those images disappeared again.

"This light array doesn't look simple. Everyone, be careful and don't get close to it." Lin Yun reminded. He had an ominous premonition in his heart, thinking that this light array might bring new dangers.

However, the light array seemed to have a strong attraction, and everyone felt their bodies moving slowly towards the light array uncontrollably.

"Oh no, this light array is sucking us in!" Lin Xiao shouted. He tried to use his spiritual power to stabilize his body, but the attraction was too strong and his efforts had little effect.

Everyone panicked, using various methods to try to break free from the light array's pull. Some team members used all their spiritual energy to fight the attraction, while others took out magic weapons, hoping they would work to block the suction.

Lin Yun also gritted his teeth and gathered all his spiritual energy into his feet, trying to root himself to the ground to prevent himself from being sucked in. At the same time, he did not forget to tightly protect the "Chaos Spirit Art" in his hand. This was a treasure they had obtained with great difficulty and he must not lose it.

As everyone struggled, the attraction of the light array became stronger and stronger, and everyone was getting closer and closer to the light array.

Just when everyone thought they were about to be swallowed by the light array, suddenly, the light of the light array dimmed suddenly, and the powerful attraction disappeared in an instant.

Everyone breathed a sigh of relief, but before they could recover, the light array underwent new changes.

I saw a sphere emitting dazzling light slowly rising in the center of the light array. Various mysterious runes were flowing on the surface of the sphere. Those runes were flashing with light, as if telling ancient secrets.

"What is this?" Everyone looked at each other, all a little overwhelmed by this sudden change.

Lin Yun stared at the sphere, pondering. He felt that the sphere might be closely related to the ruins. Perhaps it was an extremely valuable treasure, or the key to unlocking more secrets of the ruins.

But he also knew that in these ruins full of mystery and danger, anything that seemed tempting might hide huge dangers.

"Everyone, don't rush to act. Let's observe first." Lin Yun said. He hoped to find out the details of the sphere before taking action to avoid falling into danger again.

After hearing Lin Yun's words, everyone nodded, temporarily suppressing their curiosity and impulses. They stood quietly in their places, staring at the glowing sphere, waiting for the next development...
