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

Lin Yun and the others flew towards the suspicious valley. The closer they got, the stronger the mysterious aura became. When they reached the valley's entrance, they slowly descended and carefully examined the faint spiritual energy curtain before them.

This light curtain seems weak, but it actually contains a hidden power. Lin Yun tried to touch it lightly with his spiritual power. The light curtain rippled slightly, but there was no strong rebound. However, he could feel that there seemed to be complex forbidden runes running in it. If he rushed in rashly, it might trigger danger.

"Everyone, be careful. This light curtain is not simple. Don't rush in. See if you can find a way to crack or bypass it." Lin Yun whispered. Everyone nodded, and each used their own abilities to begin exploring around the valley entrance.

Chen Yu used the spiritual power perception technique and moved slowly along the edge of the light curtain, trying to find the place where the spiritual power was relatively weak; Wang Lin squatted down and carefully observed whether there were rune clues related to the light curtain on the ground and the surrounding rocks, hoping to find a way to crack it; Su Yao closed her eyes, relying on her keen perception of spiritual energy, feeling the unique spiritual power fluctuations emitted by the light curtain, trying to analyze its characteristics; Zhao Gang held a shield and stood vigilantly behind everyone, guarding against possible emergencies.

After careful exploration, Wang Lin made the first discovery. At the base of a boulder near the valley entrance, she found several small rune marks that corresponded to the runes on the light curtain. These marks were partially obscured by dust and could easily be overlooked without careful inspection.

"Senior Brother Lin Yun, I have a discovery here. I think these rune marks may be the key to controlling the light curtain. Perhaps we can open a gap by changing the order in which they input spiritual power." Wang Lin said excitedly. As he spoke, he took out several specially made talismans and prepared to try to crack them.

Everyone gathered around, and Wang Lin, according to his own speculation, pasted the talismans on the rune marks in a specific order, and then carefully guided everyone to inject spiritual power together. As the spiritual power was slowly injected, the rune light at the corresponding position on the light curtain began to flicker, and then a narrow gap appeared on the light curtain that was only wide enough for one person to pass through.

"Well done, Wang Lin! Let's go in quickly, and move quickly. This gap probably won't last long." Lin Yun praised, and was the first to move sideways into the valley through the gap. The others followed quickly in turn. After the last person entered, the gap slowly closed and returned to its original state, as if nothing had happened.

After entering the valley, everyone found that this place was completely different from the noisy and chaotic place of conflict outside. The entire valley was eerily quiet, without a sound. Only the sound of their footsteps echoed in the empty valley, which made people feel a little creepy.

The valley was thick with fog, and visibility was very low. The crowd could only vaguely make out some strange-looking plants growing around them. These plants emitted a faint fluorescent light, appearing quite mysterious in the mist. The road under their feet twisted and turned, leading deep into the valley. They didn't know what awaited them at the end.

"Everyone, stay close. This place has a strange aura. Don't get lost," Lin Yun said in a low voice, gripping his staff tightly. His spiritual energy was quietly flowing, ready to respond to any danger. Everyone else was also extremely alert, carefully moving forward along the road, vigilantly observing their surroundings.

As they walked, the fog ahead gradually dissipated, revealing an ancient and mysterious building. Dark in color, its style simple yet majestic, its walls covered in a variety of obscure runes and patterns. Some depicted ancient sacrificial rituals, while others seemed to illustrate mysterious immortal cultivation rituals. The sight of this place only deepened the sense of hidden secrets.

The door of the building was tightly closed, and there were also complex forbidden runes on the door that were flickering, as if warning everyone not to approach easily.

"This building looks quite old. Maybe it contains the clues about the mysterious force we are looking for." Su Yao said softly, her eyes full of curiosity and vigilance.

Lin Yun nodded and said, "Well, but the restriction on this door looks difficult to deal with. Wang Lin, please try harder and see if you can break it."

Wang Lin responded, walked forward, and began to carefully examine the runes on the door, trying to find a clue to crack it. The others spread out around, guarding vigilantly in case of any unexpected situation.

Wang Lin studied the restriction on the door with rapt attention, her brow furrowed, then relaxed. She constantly changed the way the talismans were used, her spiritual energy flowing through her fingertips as she carefully touched the runes on the door. After much arduous exploration and experimentation, she finally found the key node of the restriction. She then took out several carefully prepared spiritual energy sealing talismans and affixed them to the nodes in a specific order, guiding everyone to infuse spiritual energy into them, enhancing their power.

With a fluctuation of spiritual power, the forbidden light on the door gradually dimmed, and then there was a "click" sound. The door slowly opened, and an old and rotten breath mixed with a trace of mysterious spiritual power rushed in, making everyone cover their mouths and noses.

"Let's go in and take a look. Everyone be careful." Lin Yun said, taking the lead and stepping into the building, with everyone following closely behind.

The space inside the building is very spacious and dimly lit. There are rows of stone platforms all around, on which are placed some bottles and jars, ancient books and strangely shaped magical objects. There are also many rotten wooden boxes piled up in the corners, as if this was once a warehouse for storing important items, but now it exudes an air of desolation and decay.

The crowd dispersed and began to search for items on these stone platforms, hoping to find clues related to the mysterious force.

Chen Yu picked up an ancient scroll and gently opened it. He found that the text on it was obscure and difficult to understand, but he could vaguely see that it recorded some information about a mysterious organization. This organization seemed to be good at manipulating people's hearts and secretly planning various conspiracies in an attempt to disrupt the situation in the world of immortal cultivation and seek benefits.

"Brother Lin Yun, come and take a look. This scroll seems to mention something similar to the mysterious force we are looking for." Chen Yu shouted. Lin Yun hurried over, took the scroll and examined it carefully. Although he could not fully decipher the contents, he was sure that this was a very important clue.

At the same time, Su Yao found a small jade bottle emitting weak spiritual fluctuations in a corner. She opened the bottle cap and a pungent smell came out. There was some black powder in the bottle. The powder had a special spiritual aura, which was somewhat similar to the abnormal spiritual fluctuations that appeared on the immortal cultivators who were caught in the dispute outside.

"Look at this, this black powder may be related to the inexplicable disputes among those immortal cultivators outside." Su Yao said. Everyone gathered around and looked at the black powder. They felt more and more that everything in the valley was inseparable from the chaotic situation outside.

Just as everyone gathered together to study these clues, suddenly, several black shadows rushed out from the dark corner of the building. The shadows were extremely fast and rushed towards everyone, bringing with them a gust of gloomy cold wind that made people shiver.

Lin Yun reacted quickly, waving his staff and unleashing a spiritual energy curtain to block the approach of the shadow. The other team members also employed their skills to resist. Su Yao played the Lingxi Jade Flute, and the spiritual energy waves transformed into spiritual blades, shooting towards the shadow. Chen Yu used the stealth technique to instantly disappear from his position and circled behind the shadow, preparing for a sneak attack. Wang Lin continuously threw talismans, some of which transformed into blazing flames, while others formed into tough ropes, beckoning towards the shadow. Zhao Gang raised his shield and stood firmly in front of the group, blocking the shadow's direct attack.

But these black shadows were extremely agile. They easily avoided the attacks of the crowd and then rushed towards them again, as if they had their own consciousness. Moreover, they exuded a strange aura, which made people feel very dangerous.

In the fierce confrontation, Lin Yun finally saw the true identity of the black shadows. They turned out to be some puppets that looked like humans. These puppets were completely black, with their eyes flashing with a faint green light, and wisps of black smoke constantly coming out of their joints. They were extremely agile and ruthless, and every attack carried a strange power that made it impossible to defend against them.

"Everyone be careful, these puppets are not simple, the power on them is very strange, don't get hit by them!" Lin Yun warned loudly, and at the same time launched a stronger spiritual attack. The top of the spiritual staff bloomed with brilliant spiritual light, turning into spiritual patterns, entwining towards the puppets, trying to restrict their movements.

Su Yao and the others also adjusted their attack strategy according to Lin Yun's reminder, focusing their efforts on attacking the puppets' joints, trying to disrupt their mobility and slow down their attack speed. However, these puppets were also very defensive, and ordinary attacks on them could only leave shallow scratches, not cause any substantial damage to them. For a time, everyone was once again caught in a difficult battle.

While struggling to fend off the puppet's attacks, Lin Yun observed its movements and pondered a countermeasure. He discovered that whenever the puppet launched a powerful attack, a red crystal would flicker on its chest, seemingly the core of its power. Furthermore, this crystal seemed more fragile than other parts of its body.

"Everyone, pay attention, attack the red crystals on their chests, that might be their weakness!" Lin Yun shouted, and then increased his spiritual power to the extreme, unleashing his strongest spiritual attack. With a wave of his spiritual staff, a giant spiritual sword energy slashed fiercely at the red crystal on the chest of a puppet.

Upon hearing this, the other team members followed suit, concentrating their efforts on attacking the puppet's red crystal. Su Yao's spiritual blades converged into a powerful spiritual storm, sweeping towards the puppet's vitals. Chen Yu and Wang Lin also exerted all their strength, focusing their spiritual attacks and the power of their talismans on that single point. Zhao Gang steadied himself to the side, using his shield to block the puppet's counterattacks, creating opportunities for his teammates to attack.

With everyone's concerted attack, the red crystals on the chests of several puppets finally shattered. They instantly lost their ability to move and collapsed to the ground, turning into a pile of scrap metal that scattered across the ground. Seeing the effect, everyone's morale was boosted, and they continued to attack other puppets using this method, gradually turning the tide of the battle.

After repelling the puppets, everyone was exhausted, but they had no time to rest, because they knew very well that the secrets hidden here were far from being revealed. The true face of the mysterious force and their specific plans might need to continue exploring in this valley to know.

"Everyone, let's recover our spiritual power first, and then continue looking inside. Maybe there are more important clues waiting for us." Lin Yun said. Everyone took out the pills and swallowed them, adjusted their state, and then walked carefully towards the depths of the building, ready to explore the deeper secrets. The many doubts shrouding the mysterious force were also waiting for them to be unraveled step by step.
