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

Lin Yun watched helplessly as the hideous faces emerged from the black smoke surrounding the treasure box and roared towards them, his heart tightening. This journey had been filled with dangers. He had thought he was one step closer to unlocking the secret, only to find himself in such a desperate situation. There was no peace for a moment, he sighed inwardly.

At this moment, the surroundings grew increasingly eerie. The walls, covered in sharp spikes, flickered with a cold light, as if countless pairs of eyes were watching from the shadows, ready to strike a fatal blow. Scalding magma surged beneath their feet, and a pungent odor filled their nostrils, making them feel as if they were in the depths of hell, where every breath carried a scorching heat and the threat of death.

"Everyone, be careful! These ghost faces are definitely tough to deal with. Don't disperse yet! Maintain a tight formation!" Lin Yun shouted, his voice echoing in the oppressive space, tinged with a subtle tension. He gripped the sword tightly, and the spiritual light on the sword flickered slightly, as if responding to its master's determination, or perhaps seeking a little comfort in the darkness.

Upon hearing this, the teammates quickly gathered together, forming a circle with their backs to each other, each preparing to fight the enemy. Su Yao quickly formed seals with her hands, muttering something to herself, and a spiritual shield slowly rose around them. Although the shield seemed a little thin in this harsh environment, it was better than nothing. Li Feng tightened his gauntlets, his eyes revealing a fierceness. He squatted slightly, like a cheetah ready to pounce on the enemy at any time. Chen Yu held the flame gourd in his arms, and with his other hand, he quickly formed seals, adjusting the power of the flames in the flame gourd, waiting to give these ghost faces a heavy blow at the critical moment. Lin Wan'er concealed her figure and moved quietly around, relying on her keen perception to find the flaws of the ghost faces, ready to deliver a fatal blow from the side.

In a flash, those ghost faces rushed forward, baring their fangs and claws, and making sharp whistling sounds from their mouths, as if the evil spirits from the Nine Nether Hell were venting their anger.

Some of the ghost faces extended long, bony claws, gleaming with an eerie black light, and scratched fiercely at the spiritual shield. Each scratch caused a violent ripple in the shield, and the light flickered, as if trembling in pain. Lin Yun was secretly shocked. The attack power of these ghost faces was so strong that the shield might not hold out for much longer. He couldn't help but worry about the safety of everyone.

Other ghostly faces opened their bloody mouths, spewing out streams of black, smoke-like air, carrying a rancid stench that quickly enveloped the crowd. Li Feng, upon seeing this, roared and dashed out of the defensive circle, using his gauntlets to protect him as he charged towards the black smoke. He swung his fists, each one carrying immense force, attempting to disperse the black smoke. However, the black smoke, as if alive, tightly wrapped around his arms, constantly corroding the gauntlets with a sizzling, corroding sound that caused a sharp pain in his arms.

Su Yao was on the side, doing her utmost to maintain her shield while continuously casting supporting spells to restore her teammates' spiritual energy. Her forehead was already covered with fine beads of sweat, and her hands were forming seals faster and faster, but the speed at which her spiritual energy was depleting was still making her anxious. She thought to herself, this can't go on. She had to find a way to find the weaknesses of these ghost faces, otherwise everyone would be buried here.

Chen Yu seized the opportunity, shook the Flame Gourd, and chanted an incantation. A blazing flame shot out from the gourd's mouth, consuming the ghostly faces emitting black smoke. Wherever the flame passed, the black smoke instantly evaporated, but the ghostly faces only retreated slightly, suffering no significant damage. Chen Yu frowned, thinking to himself, these ghostly faces are indeed a formidable threat. Ordinary attacks don't seem to have much effect on them. He needs to find another way.

Lin Wan'er observed the ghost faces' every move from concealment. She noticed that after launching an attack, the light in their eyes would briefly flicker, as if they were gathering strength or recovering some kind of energy. She wondered if this was their weakness. But she couldn't be sure yet; she needed to observe further.

In this fierce battle, Lin Yun struggled to resist the attacks of the ghost faces while carefully observing their every move. He knew that if he wanted to survive in this desperate situation, he had to find the flaws of these ghost faces.

Seeing the flashes of light in the eyes of some of the ghost faces after their attacks, Lin Yun's heart stirred. He remembered that Lin Wan'er seemed to have noticed this detail before. Could this really be their weakness? His eyes were fixed on the ghost faces, trying to find more clues.

As Lin Yun observed more deeply, he discovered that whenever the ghost faces' eyes flickered, their movements would slow down for a moment, as if their control over their bodies had been temporarily interrupted. Furthermore, at this time, their originally eerie aura would also weaken slightly.

"Everyone, pay attention. When the eyes of these ghost faces flash after attacking, their movements will slow down and their breath will weaken. This may be their weakness. Concentrate your strength to attack that part later!" Lin Yun shouted loudly, with a hint of excitement in his voice, as if he saw a ray of light in the darkness.

Upon hearing this, the teammates focused their attention on the ghost face's eyes. At this moment, the battle continued, and every moment was full of danger, but a glimmer of hope ignited in everyone's hearts, hoping that this discovery could be the key to turning the tide.

Not long after, a ghost face launched a fierce attack. After the attack, as Lin Yun observed, its eyes began to flicker, its movements slowed down, and the gloomy aura on its body was obviously weakened.

"Now, attack!" Lin Yun shouted, and the sword in his hand shone brightly, bringing with it a sharp sword energy, and stabbed accurately at the part of the ghost face's eyes where the light was flashing.

Su Yao also quickly formed seals with her hands, muttered something, and cast an auxiliary spell to enhance the power of the attack, bringing the power of her teammates' attack to a new level.

Li Feng endured the pain in his arm and rushed forward again. He swung his gauntlet and struck at the glowing part of the other ghost face's eyes.

Chen Yu adjusted the angle of the flame gourd and sprayed the flame accurately onto the part of another ghost face's eyes where the light was flashing.

At the right moment, Lin Wan'er appeared from behind the enemy, holding a special dagger in her hand, and stabbed it fiercely at the part of the ghost face where the eyes were flashing.

After everyone worked together, finally, the flashing parts of the eyes of several ghost faces were broken under the concentrated attack of everyone. Those ghost faces let out a shrill scream, their bodies began to tremble violently, and then they fell to the ground with a bang, turning into a cloud of black smoke and dissipating in the air.

Seeing that there was a turning point, everyone cheered up and continued to attack other ghost faces using the same method.

As more and more ghost faces were defeated by the crowd's concentrated attacks, their attack rhythm was disrupted, they began to panic, and their numbers gradually dwindled. Lin Yun and the others seized this opportunity, gritted their teeth, and continued to launch even more fierce attacks.

"Don't stop, keep attacking, and take the opportunity to rush towards the treasure box!" Lin Yun shouted loudly. He gripped the sword in his hand tightly and once again unleashed a series of sharp sword energy, rushing towards the remaining group of ghost faces.

Li Feng used his gauntlets to block some of the attacks for his teammates and protect those behind him. His movements were even more courageous, and every punch and kick was powerful enough to repel the approaching ghost faces.

Su Yao cast auxiliary spells on the side to enhance everyone's defense and restore spiritual power, ensuring that everyone can continue to maintain their combat effectiveness in this fierce battle.

Chen Yu shook the flaming gourd and chanted a spell. Streams of blazing flames shot out from the mouth of the gourd and burned towards the ghost faces on both sides, distracting their attention and creating better conditions for rushing to the treasure box.

Lin Wan'er was still hiding her figure. She shuttled among the enemy group, looking for the weak link in the Ghost Face encirclement so that she could deliver a fatal blow and help her teammates rush to the treasure box smoothly.

Finally, after everyone's desperate efforts, they successfully broke through the encirclement of the ghost faces and rushed towards the stone platform where the colorful treasure box was placed. Although the ghost faces tried to chase them, they were somewhat embarrassed by the attack from Lin Yun and others, and for a while they did not dare to pursue rashly.

Lin Yun's heart was filled with excitement and anticipation. After overcoming numerous difficulties, he finally had a chance to approach the treasure box that might hold a huge secret. He prayed silently that he could successfully obtain the treasure box, solve all the mysteries, and find a way out of this hellish place.

When Lin Yun and others ran to the stone platform breathlessly, they found that things were not that simple.

A faint golden light permeated the stone platform. This light seemed gentle, but in fact it contained a powerful restraining force. When Lin Yun reached out to touch the stone platform, a powerful rebound force bounced his hand back, almost causing him to fall to the ground.

"This...what's going on? I finally broke through the encirclement of the ghost faces, but I didn't expect there would still be this restriction blocking me." Lin Yun frowned, feeling helpless and anxious. He carefully observed the golden light around the stone platform, trying to find a way to break the restriction.

Su Yao also stepped forward and cast a detection spell, quickly forming seals with her hands and muttering something. After a while, she opened her eyes and said solemnly, "Lin Yun, I've detected that the power of this restriction is very strong, and it seems to be closely connected to the spiritual power structure of this entire space. To break it, you need to find the corresponding spiritual power key, or trigger the surrounding runes in a certain order."

Upon hearing this, Lin Yun groaned inwardly. He had already encountered so many difficulties and obstacles along the way, and now he hadn't expected to face such a difficult restriction. He looked around and found that the stone platform was engraved with various complex runes. These runes emitted a faint glow, reflecting the surrounding golden light, as if revealing their own mystery.

"Everyone, look carefully and see if you can find any clues nearby, or any special marks or something like that. Maybe we can find a way to break the ban." Lin Yun said to his teammates. Although he was not sure, he could only hope that everyone could find a solution together.

So, everyone began to search carefully around the stone platform, not missing any corner that might contain clues.

During the search, Chen Yu found a small depression on the ground on one side of the stone platform. There were some tiny runes engraved in the depression. These runes were different from the runes around the stone platform. They emitted a faint blue light and were particularly eye-catching against the backdrop of the golden light.

"Lin Yun, there is a depression here with some runes engraved inside. It seems to be related to this restriction!" Chen Yu shouted.

Upon hearing this, everyone gathered around. Lin Yun squatted down and carefully observed the runes. He discovered that the shape and arrangement of the runes seemed to imply a certain order, and that the blue light they emitted seemed to echo the golden light surrounding the stone platform.

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

Su Yao also leaned in to observe carefully. She gently placed her hands on the runes, trying to sense the flow of spiritual power within them. After a while, she said, "Lin Yun, I feel like these runes are releasing spiritual power according to a specific rhythm, and this rhythm seems to be related to the spiritual power structure of the restriction in some way, but I'm not quite 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 runes and the changes in the strength of the spiritual energy they emitted. Suddenly, he noticed that the flashing frequencies of several of the runes would briefly synchronize after a period of time, as if transmitting some kind of signal.

"Everyone, pay attention to the flashing frequency of these runes. I think there may be something interesting here. Maybe if we operate or trigger something according to this frequency, we can break the restriction." Lin Yun said.

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

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

When he touched the last rune, the golden light around the stone platform suddenly flickered, and then the light gradually dimmed, and the powerful restrictive force also disappeared.

"Success!" Lin Yun shouted excitedly. He couldn't wait to walk up to the stone platform and reach out to take the treasure box that was emitting colorful light.

The moment his hand touched the treasure box, a warm spiritual energy flowed through his arm and into his body, making him feel comfortable. He carefully picked up the treasure box and found it light in his hand. The surface was engraved with exquisite patterns. These patterns emitted a soft glow, as if telling of its extraordinaryness.

At this moment, Lin Yun's heart was filled with anticipation. He didn't know what was inside the treasure box, but he was convinced that it must be the key to unlocking all the secrets.

However, just as he was about to open the treasure box to check the contents, suddenly, a melodious music came from the treasure box. The music echoed in this silent space, seeming particularly ethereal.

Immediately afterwards, the patterns on the treasure box's surface began to flow, as if coming alive. Then, the treasure box slowly opened, and a dazzling white light shot out from within, enveloping Lin Yun and the others.

Within this white light, Lin Yun seemed to see some blurry images. These images seemed to show some ancient scenes, with mysterious cultivators performing some kind of ritual, and some strange creatures soaring in the sky. But these images were fleeting, and before he could see clearly, the white light gradually disappeared.

When the white light completely disappeared, Lin Yun discovered that the treasure box was empty except for a piece of paper emitting a faint glow. He picked up the paper and saw a line of words on it: "To know the truth, find the lost key."

Lin Yun frowned, his heart filled with confusion. The Lost Key? What was that? It seemed they still had a long way to go before truly unlocking the secret.
