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

Lin Yun clutched the faintly glowing slip of paper he'd taken from the treasure box, his brow furrowed, his heart filled with confusion and bewilderment. "To know the truth, retrieve the lost key." These few words seemed like a fog, shrouding their newly ignited hope.

He wondered what exactly this lost key was. Where could it be in this mysterious space? Or had it vanished with the passage of time? He had come this far, through countless hardships and dangers, thinking that obtaining the treasure box would unlock all the secrets. But now, he was trapped in this quandary, a truly frustrating predicament.

Even then, their surroundings still exuded a mysterious and dangerous aura. The walls, covered in sharp spikes, still emanated a cold glow, as if silently warning them of the dangers within. The scalding lava beneath their feet continued to surge and swell, a pungent odor permeating the air, a constant reminder of their vigilance. The stone platform where the treasure box had been placed, now dimmed without the box's light, still lingered faintly. The lingering spiritual energy still emanated faintly, as if to reassure them that what had just occurred was not an illusion.

"Everyone, don't panic. Let's think carefully. This lost key is definitely not without a trace. Perhaps we've seen related clues in this space before, but just didn't notice them at the time." Lin Yun took a deep breath, trying to calm himself, and said to his teammates. He knew that panicking at this moment was useless. Only by calming down and reorganizing the clues could he find the next step.

Upon hearing this, the teammates nodded and fell into deep thought. Su Yao folded her arms and frowned slightly. Her eyes scanned the surrounding environment, as if trying to find some inspiration from this familiar yet unfamiliar scene. Li Feng clenched his fists, his face serious. He silently recalled every detail of the previous battle and exploration in his mind, hoping to find some key information that he had missed. Chen Yu gently shook the flame gourd, a glimmer of thought in his eyes. He was also trying to think about the possible hiding place of the lost key. Lin Wan'er was hiding on the side. Although her figure was invisible, Lin Yun could feel that she was also concentrating on thinking. Her keen perception might be able to discover some clues that others had overlooked.

Lin Yun decided to resume his exploration around the stone platform. After all, since the treasure box had appeared there, perhaps clues related to it weren't too far away. He squatted down and carefully examined every corner of the stone platform, gently touching the runes on its surface, which had become somewhat dim, trying to sense any unusual spiritual fluctuations or hidden information.

"These runes seemed to be related to the treasure box's restrictions before. Could they also be connected to the Lost Key?" Lin Yun pondered as he explored them. However, apart from being able to sense the faint spiritual energy remaining on the runes, he didn't find any particularly obvious clues.

He stood up and looked around, his eyes landing on the boiling lava. The roiling lava suddenly reminded him of the unusual direction of the lava flow he had seen before when he entered this space. However, he had been distracted by the ghost face attack and hadn't investigated further.

"Do you remember the direction of the magma flow when we first came in? I always feel something is wrong. Maybe there are some clues hidden there." Lin Yun said loudly, his eyes fixed on the magma, with a hint of expectation in his eyes, hoping that his teammates could recall the relevant details like him.

Su Yao was slightly stunned when she heard this, then she closed her eyes and began to recall the scene when she first entered the space. After a while, she opened her eyes and said, "Lin Yun, now that you mention it, I seem to have some impression. At that time, I felt that the flow of magma did not seem to be formed naturally, but seemed to be guided by some force, but I couldn't tell what the specific force was."

Li Feng also scratched his head and said, "I was so focused on guarding against those thorns at the time that I didn't pay much attention to the lava. But now that I hear what you said, it really does seem a bit strange."

Chen Yu shook the flame gourd and said, "Anyway, let's go over and take a look. Maybe we can find something."

Lin Yun nodded and said, "Okay, everyone, be careful. The temperature of this lava is extremely high. Don't fall in. Let's walk along the edge of the lava and see if we can find anything unusual."

With that, Lin Yun took the lead, heading towards the edge of the lava, followed closely by his teammates. They walked cautiously, avoiding the occasional bubbles rising from the lava with every step, fearing burns. The scorching heat hit them, making it difficult to breathe, but they gritted their teeth and persevered in their pursuit of the Lost Key.

After walking along the edge of the lava for a while, Lin Yun suddenly noticed a distinct vortex forming in the lava flow not far ahead. The vortex spun incredibly fast, drawing the surrounding lava in, forming a deep, dark red pit. Furthermore, a faint wave of spiritual energy seemed to emanate from this pit. Although weak, it stood out against the scorching lava.

"Everyone, look over there! The lava flow is anomalous. That vortex pit seems unusual. Perhaps it's related to the Lost Key. Let's go take a look, but be careful of the heat of the lava." Lin Yun pointed at the vortex pit ahead, his heart filled with curiosity and a hint of worry. Curious about the secrets hidden behind the vortex pit, worried about the danger of the lava that could bring them harm at any time.

Upon hearing this, the teammates all looked in that direction, their eyes revealing caution and expectation.

They slowly approached the vortex pit. When they were a few steps away, Lin Yun felt the spiritual energy fluctuations become more pronounced. He stopped and carefully observed the pit, noticing that there seemed to be some tiny runes carved on the edge of the pit. These runes were faintly visible under the reflection of the dark red light, exuding a mysterious aura.

"These runes..." Lin Yun squatted down and wanted to take a closer look, but at this moment, a powerful suction force suddenly surged out from the pit and sucked him in in an instant.

"Lin Yun!" His teammates shouted as they tried to reach out and pull him, but they only managed to grab onto air. Then, they were also sucked into the pit by the suction force.

Everyone felt a flash of light before their eyes, and then they were swept into a completely new space. When they steadied themselves and took in the surroundings, they couldn't help but gasp in shock at what they saw.

This was an extremely strange space. The sky was a deep purple, as if woven from countless layers of mysterious purple veils. Between these veils shimmered tiny star-like lights, appearing and disappearing as if playing a game of hide-and-seek with the crowd. The ground was paved with a soft blue crystal. The surface of the crystals was as smooth as a mirror, and each piece was engraved with exquisite patterns. These patterns seemed to flow, constantly changing shape and color, dazzling the eyes.

In the center of the space stood a massive, pagoda-like structure. The pagoda radiated a golden glow, its every tier clearly visible. Each floor boasted unique decorations. Some featured exquisite railings carved with lifelike mythical beasts, while others held enormous wind chimes. Gently swaying in the breeze, they emitted a clear, melodious sound that resonated throughout the silent space, as if telling an ancient story.

On the top floor of the pagoda, there is an object emitting dazzling white light. The shape of the object is like a key, and the key is engraved with complex runes and patterns. The runes and patterns are flashing with colorful light, as if showing its extraordinaryness to everyone.

"Could it be... that's the Lost Key?" Lin Yun was startled, a flicker of surprise and anticipation in his eyes. He hadn't expected to find a clue related to the Lost Key so quickly. In other words, it was very likely the Lost Key they had been searching for.

But he also knew that in this mysterious space, things would never be so simple. This pagoda looked magnificent, and must be protected by numerous mechanisms and restrictions. If he wanted to obtain the object that seemed to be the lost key, he would probably have to go through a difficult test.

Lin Yun was feeling a mixture of excitement and nervousness. He was excited because they might have found the key, yet nervous about the unknown challenges they faced. He secretly clenched his fists and said to himself, "No matter what, I must get that key, unlock all the secrets, and find a way out of here."

Lin Yun took a deep breath and turned to his teammates, saying, "Everyone, be careful. That pagoda doesn't look simple. It must have many traps and restrictions. Let's slowly approach it, observe the surroundings, and then find a way to go up and get the key."

The teammates nodded to show that they understood.

They walked towards the pagoda cautiously, taking every step with extreme caution, fearing that they would trigger any mechanism or cause new danger. When they were still some distance away from the pagoda, Su Yao suddenly stopped and said solemnly, "Lin Yun, I have detected strong spiritual fluctuations around this pagoda, and these fluctuations seem to be operating according to certain rules. There must be a lot of mechanical restrictions set up. I also feel that there is a particularly strong restrictive force at the entrance of the pagoda, as if it is preventing anyone from entering."

Lin Yun frowned upon hearing this and said, "Then let's look around here first to see if there are any clues that can help us break through these restrictions, or if there are any special markings or something like that. Maybe we can find a way to enter the pagoda through them."

So, everyone spread out around the pagoda and began to search carefully, examining the crystals on the ground, the surrounding space, and the walls of the pagoda itself, leaving no corner that might hold a clue.

During her search, Lin Wan'er, with her keen senses, discovered some strange protrusions at the base of the pagoda's wall. These protrusions were circular, with tiny runes engraved on their surfaces. The runes emitted a faint green glow, forming a sharp contrast with the golden light of the pagoda, making them quite eye-catching.

"Lin Yun, there are some strange protrusions here, which seem to be related to the mechanism and restrictions of this pagoda!" Lin Wan'er called softly. Although her voice was soft, it was clearly audible in this silent space.

Upon hearing this, everyone gathered around. Lin Yun squatted down and carefully observed the bumps. He discovered that the arrangement of these bumps seemed to have some pattern, and the changes in the intensity of the green light they emitted seemed to hint at something.

"These protrusions are not simple. I think they may be the key to breaking the mechanism of this pagoda." Lin Yun stood up and continued to look at the protrusions, trying to find some clues from their arrangement, runes and light changes.

Su Yao also leaned in to observe carefully. She gently placed her hands on the bulges, trying to sense the flow of spiritual energy. After a while, she said, "Lin Yun, I feel like these bulges are releasing spiritual energy in a specific order, and this order seems to be related to the spiritual energy fluctuation pattern around the pagoda. However, I'm not sure what the specific connection is."

Lin Yun's heart skipped a beat when he heard this. He squatted down again, carefully comparing the differences between the bumps and the changes in the strength of the spiritual energy they emitted. Suddenly, he noticed that the flashing frequencies of several of the bumps would briefly synchronize after a period of time, as if transmitting some kind of signal.

"Everyone, pay attention to the flashing frequency of these protruding lights. I think there may be something going on. Maybe by operating or triggering something according to this frequency, we can break the mechanism and restrictions of this pagoda." Lin Yun said.

Upon hearing this, everyone focused their attention on the bumps, carefully observing their flashing light.

Lin Yun decided to try triggering the bumps according to the frequency of their flashing lights to see what effect it would have. He took a deep breath, then gently touched the bumps one by one in the order he had observed them, the interval between each touch strictly following the synchronized frequency of the flashing lights.

As he touched the last protrusion, the spiritual energy surrounding the pagoda suddenly surged, and the previously calm golden light began to flicker. Then, the powerful restraining force gradually dissipated at the pagoda's entrance, as if a tightly closed door had finally been opened a crack.

"Success!" Lin Yun shouted excitedly. He couldn't wait to run towards the entrance of the pagoda, and his teammates followed closely behind.

They climbed up the stairs inside the pagoda, floor by floor. Each floor had different scenes and traps, but with everyone's concerted efforts, they were all solved one by one.

Finally, they reached the top floor of the pagoda. The object, emitting a dazzling white light and resembling the lost key, lay before him, and Lin Yun's heartbeat quickened.

He slowly walked forward, reached out, and carefully picked up the key. The moment his hand touched the key, a powerful spiritual energy surged into his body, filling him with strength. The key felt heavy in his hand, and the runes and patterns engraved on it appeared more clearly before him, as if telling of its antiquity and mystery.

However, at the moment when Lin Yun picked up the key, suddenly, a low buzzing sound came from inside the pagoda, as if some alarm was triggered.

Immediately afterwards, some huge and ferocious monsters emerged from all corners of the pagoda. They walked slowly towards Lin Yun and others with heavy steps, with fierce murderous intent in their eyes.
