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

Lin Yun and others slowly approached the black fog that shrouded the mysterious underground valley. The closer they got, the stronger the evil spiritual power fluctuations became, as if countless pairs of eyes hidden in the dark were spying on them, which made people shudder.

"Everyone, be careful. This fog is weird. Don't rush in. I'll try to use my spiritual power to detect the situation." Lin Yun said in a low voice, then carefully extended a wisp of spiritual power and slowly extended it towards the black fog.

But as soon as that wisp of spiritual power came into contact with the fog, it was as if it was swallowed by something and disappeared without a trace in an instant. At the same time, a low roar came from the fog, as if warning everyone not to get close.

"This fog can actually devour spiritual energy. It seems that we can't force our way in. We have to find another way." Lin Yun said with a frown. Everyone also looked solemn and gathered together to discuss countermeasures.

After carefully observing the surroundings, Chen Yu found that although the black mist looked integrated, the flow of the mist seemed to be slightly slow in some places, with slight differences from other areas.

"Look over there, the flow of fog in those areas is different. Maybe those are the spots where the fog is relatively weak. We can go over and take a closer look." Chen Yu said, pointing to a place not far away. Everyone looked in the direction he pointed, and indeed, they found those unusual places.

As a result, everyone cautiously approached the suspected weak points, remaining vigilant with every step, always prepared for any unexpected situation. As they approached, Lin Yun once again extended his spiritual power to sense the mist, discovering that while it still absorbed spiritual power, the rate of absorption had significantly slowed, and spiritual power could penetrate a short distance into the mist. This gave everyone a glimmer of hope.

"Maybe we can try to break in from here. Let's hold hands, gather our spiritual power together, form a whole, and support each other as we move forward." Lin Yun suggested. Everyone nodded, and then followed the method Lin Yun said. They held hands, slowly released their spiritual power, gathered it into a spiritual power shield, and then slowly advanced towards the black fog.

At first, progress was smooth. Using the protection of their spiritual shields, they inched deeper into the fog. But before they had gone far, countless black spiritual tentacles suddenly emerged from the fog. These tentacles, as nimble as snakes, coiled around them. Once touched by these tentacles, their spiritual energy froze, stagnating, and their bodies grew heavier.

"Oh no! Everyone, use your spiritual power to attack these tentacles! Don't let them get to you!" Lin Yun shouted, and everyone quickly cast spiritual spells, attacking the tentacles. However, the tentacles continued to pour out from the mist. No sooner had they severed one than new ones emerged, and their attacks grew increasingly fierce. Gradually, everyone was overwhelmed. The spiritual shields dimmed under the constant impact of the tentacles, and everyone was in a very difficult situation.

The attacks of the black spiritual tentacles became more and more ferocious. Not only did they continuously attack everyone's spiritual shields from the front, but some tentacles also quietly came around from below and behind, trying to catch everyone off guard.

Su Yao played the Lingxi Jade Flute, and the music turned into spiritual blades containing purifying power, shooting towards the area where the tentacles were densely packed, trying to cut off the approaching tentacles. Although the purifying power could cause some damage to the tentacles, the effect was not ideal. The tentacles only retreated briefly and soon pounced on them again; Chen Yu hid his body, shuttled between the tentacles, and chopped at their roots with a spiritual dagger, but the fog was too thick and his vision was blocked. It was difficult for him to accurately find the vital parts of the tentacles, and the efficiency of the attack was greatly reduced; Zhao Gang stood steadily in the front, protecting everyone with a shield, and bearing most of the frontal attacks, but every collision made his arms numb and blood flowed from his mouth. The situation became very critical.

Lin Yun knew that if this continued, they would be overwhelmed by the tentacles sooner or later. He had to find a way out of this predicament as soon as possible. While maintaining his spiritual shield, he quickly pondered a countermeasure. Suddenly, he remembered that in the previous battle, the evil forces seemed quite afraid of the pure yang power. Perhaps he could try to use pure yang spiritual power to attack these tentacles.

"Everyone listen to me, try to use the pure yang power to attack these tentacles. They seem to be afraid of this!" Lin Yun shouted loudly. When everyone heard it, although their spiritual power was consumed greatly at this moment, they still mobilized the remaining pure yang spiritual power in their bodies and cast the pure yang spiritual power spells they mastered.

Suddenly, rays of blazing pure Yang energy shone through the black mist, shooting towards the black tentacles. This pure Yang energy was indeed effective. Once struck, the tentacles shrank and dissipated as if burned by a raging fire, emitting bursts of painful roars, and their originally ferocious attack momentum instantly weakened.

Seeing this, everyone was cheered up and hurriedly pursued the victory, increasing the output of pure Yang spiritual power, and beat the surrounding tentacles back step by step. The encirclement was gradually torn open. Everyone seized this rare opportunity and continued to advance into the depths of the black fog. Although they knew that the front was still full of unknown dangers, they could only move forward bravely at this moment, hoping to pass through this dangerous fog area as soon as possible and reach the mysterious underground valley.

With the help of pure yang energy, the group finally repelled the black spiritual tentacles and continued to struggle forward in the black fog. However, as they went deeper into the fog, they found themselves in a vast maze. Everything around them looked identical, and they couldn't tell east, west, south, or north. The fog also constantly interfered with their spiritual perception, and even the magic tools they usually used to determine direction became ineffective. Gradually, everyone lost their way.

"This is bad! We seem to be lost in this fog. What should we do?" Su Yao said anxiously, and everyone's face showed worry. They stopped and tried to find some clues to identify the direction, but there was nothing around except the thick black fog that could not be dissolved. Every step they took might lead them in the wrong direction. They were caught in a dilemma. If they moved forward, they were afraid of getting further away, but if they stayed, they were afraid of encountering new dangers. For a moment, they were at a loss.

Just as everyone was at a loss, Chen Yu suddenly had an idea. "We can leave unique spiritual power marks on the ground or surrounding objects at regular intervals. That way, even if we take a detour, we'll know where we've been and avoid going back and forth in circles," Chen Yu said. Everyone thought this was a feasible solution and immediately took action.

Lin Yun used his spiritual power to carve a special rune mark on a larger stone that only a few of them could recognize. Then everyone continued to move forward in one direction, leaving the same mark every time they walked a certain distance to record the route they had taken. Although the speed of progress became slower, it at least gave everyone some peace of mind, so that they would not completely lose their way in this foggy maze and wander around aimlessly.

After walking along the marked route for a distance, they suddenly began to hear a faint phantom sound. At first, it sounded like ethereal music, relaxing and delightful. But gradually, it became interspersed with strange whispers, as if bewitching everyone's minds and blurring their consciousness.

"Everyone, don't listen to that voice! It's an illusion. Stay focused!" Lin Yun hurriedly warned. Upon hearing this, everyone mobilized their spiritual energy to protect their sea of ​​consciousness, attempting to resist the influence of the phantom sound. However, the magic power of the phantom sound was so great that even with their utmost resistance, they could still feel distracting thoughts brewing in their minds, and their spiritual energy became disordered. Some team members with weaker willpower even began to walk unsteadily and their eyes became blurry, as if they would be completely controlled by the phantom sound at any moment. The situation became extremely critical.

Faced with the menacing evil phantom sound, no one dared to slack off and each used their own methods to resist the illusion.

Lin Yun took out a jade pendant emitting cool spiritual power from the storage magic weapon. This was a treasure that he had accidentally obtained in his early years and could calm his mind. He put the jade pendant on his forehead, muttered something, and used the power of the jade pendant to stabilize his mind. At the same time, he cast a spiritual spell that specifically restrained illusions, trying to dispel the phantom sounds around him; Su Yao played the Lingxi Jade Flute, changing the rhythm of the music, and played a piece of music that contained the power of clearing the mind and concentrating the mind, letting the spiritual fluctuations of the music linger around everyone, resisting the erosion of the phantom sounds; Chen Yu cast a unique concealment technique, concealing his breath and consciousness to the extreme, trying to isolate himself from the influence of the phantom sounds; Zhao Gang gritted his teeth, relying on his strong willpower to forcibly suppress the distracting thoughts in his mind, and at the same time circulated his spiritual power to form a solid spiritual shield around his body to block the invasion of the phantom sounds. Everyone was doing their best to fight this evil phantom sound, hoping to get rid of its control as soon as possible and continue to move towards their goal.

With everyone's tenacious resistance, the influence of the evil phantom sound finally weakened, and the distracting thoughts in their minds dissipated. Consciousness gradually returned, and the flow of spiritual energy slowly returned to normal. Although this battle with the phantom sound consumed a large amount of their spiritual energy and exhausted them both physically and mentally, they were fortunate to have successfully resisted the crisis and not been controlled by the phantom sound.

"Everyone okay? Let's keep going. We should be close to the underground valley now. We must hold on!" Lin Yun encouraged everyone. They supported each other and continued along the marked route. After walking a little further, they were pleasantly surprised to find that the black fog was beginning to thin out. A faint light shone through ahead, which seemed to be the exit from the foggy area. Overjoyed, they quickened their pace towards the light, as if they had seen the dawn of victory. However, they had no idea what kind of difficulties and obstacles awaited them after they emerged from the foggy area.
