In the underground palace at the bottom of the lake, a human face condensed by black mist was constantly twisting. Suddenly, the face looked at the secret door, and several small flying insects flew in.

The strange human face opened its mouth and sucked it, and several small flying insects of the machine were sucked into its mouth. After a chewing sound, I saw that the human face opened its mouth, and some metal fragments were spit out. But the next moment, more small flying insects flew in.

The face finally turned into a black mist. As soon as these black mist rolled, all the small flying insects that flew in were all swept into the black mist, and then many metal debris began to fall from the black mist to the ground. But there are still small flying insects that keep flying in.

The black mist reverted to the appearance of a human face, but it was smaller than before. Then the face was attached to a wall in a flash, and it looked like a black relief on the wall.

At that moment, the face on the wall opened its mouth again, and all the metal debris on the ground flew towards the wall. In the blink of an eye, a metal relief in the shape of a human face was literally formed on the wall.

Lin Yu, who was hiding in the puppet, had been keeping an eye on the situation in the underground palace through the power of his divine sense. He couldn't help but show a hint of surprise on his face when he saw that the black mist had turned into a relief on the wall. That black mist was too weird, although it didn't look like a primordial god or soul, but it had some abilities from a primordial god and soul.

Lin Yu has traveled to many star fields and seen many life forms in various civilizations. But it was the first time that Lin Yu had encountered such an existence in the form of a black mist.

What you don't understand is the most terrible. Because you don't know what's going to happen next.

Lin Yu is like this now. He knew he couldn't let the black fog remain in the underground palace. So Lin Yu sent a puppet with the combat power of the Yuan Infant Stage into the underground palace. The puppet carried a glittering giant sword, and slashed at the relief of the human face on the wall.

The human face relief was split by the giant sword, and then it instantly merged together, turning back into the previous human face relief.

At this time, Lin Yu commanded the second puppet to enter the main hall, although this puppet also had a blade in its hand, but instead of using a blade, it opened its mouth and spewed out a blue flame.

Flames erupted on the face relief, but the face relief was as if nothing had happened. It seems that the blue flame just now can't hurt it in the slightest.

Under Lin Yu's command, the third puppet walked into the main hall. It also didn't use a blade, but instead took out something like a bazooka. Then a crystal light shot from the barrel to the human face relief, and the temperature in the hall dropped sharply in an instant. The crystal light is actually the flame of the cold pole.

The relief of the faces on the walls remains unchanged.

Not afraid of flames, not afraid of physical attacks.

Lin Yu suddenly thought of the sky-rocketing roar, and he let out an adult sky-high roar and told it about the situation.

Roaring into the sky: "Black mist? In my memory of inheritance, I don't know what it is. But I guess the Black Mist isn't what it looks like. Although this thing does not resemble a primordial god or a soul, it may be something similar to a soul or a primordial spirit. If that's the case, my sonic attack should do some damage to it. ”

With that, it had come to the secret door.

Roar!

An invisible sonic attack went straight for the eerie relief on the wall.

Chirping!

An extremely shrill cry rang out, and the reliefs on the walls finally turned into a cloud of black mist again. This black mist is thinner than before.

Lin Yu looked at the metal shards that had fallen to the ground again, and these debris seemed to have been severely corroded by something.

The black mist is indeed an evil thing!

Roar!

Seeing that his sonic attack was effective, Roar immediately sent out an even more intense sonic wave again. In the invisible sound wave, there were countless invisible runes, which followed the sound wave towards the black mist.

The black mist suddenly diverged into hundreds of smaller fog masses, which were distributed like projectiles in all corners of the main hall. It was actually distributed into a formation. This formation negates most of the sonic attacks, but there is still a small fraction of the sonic waves that deal some damage to those tiny mistballs.

Roar! Roar! Roar!

This is one of the secret techniques of the Roar of the Sky: the Sonic Triple Slash. The sound wave was also mixed with a divine soul attack, and this move was enough to scare off the Yuanying Great Perfection Monk.

Those small fog masses seemed to know that they were powerful, and suddenly converged in one place, and instantly formed a swirling black air current.

At this moment, Lin Yu moved. He didn't do it himself, but commanded several large puppets, wielding magic weapons and giant swords, and twisted into the vortex formed by the black mist.

Laugh at! Laugh at!

The sound was like a crack, and the black mist vortex immediately collapsed.

Roar! Roar! Roar!

It's also a sonic triple slash, and this time the attack is stronger. The black mist churned and became thinner.

The adult skyscraper was about to make persistent efforts and continued to send out a triple slash. Lin Yu took out the laser shield system.

The laser shield system is a product of mortal technological civilization. Originally, this system was not used to attack, but to block the attacks of others.

Now Lin Yu is using it flexibly. This time, the laser shield system is used to attack. Tens of thousands of lasers attacked the black mist, and the black mist quickly thinned.

Roar! Roar! Roar!

Roar unleashed a third attack at the right time, and the power of the Sonic Triple Slash was brought into full play.

All the black mist suddenly turned into rune shapes, and then rushed towards Lin Yu in a flash.

Lin Yu immediately felt a crisis, he didn't think about it, he teleported the sky-high roar into the Evil King Bead, but he himself entered the internal space of the Qiankun Bead.

The black mist turned into runes that flew into the air. The few puppets that Lin Yu left in the main hall danced their giant swords like wind wheels, and continued to slash towards the runes formed by the black mist.

But all of these physical attacks don't seem to be able to hurt Black Mist. The runes formed by those black mist were constantly stirred, but there was no major change.

In the internal space of the Qiankun Pearl, Lin Yu began to let the farming system analyze the axe. Soon, a piece of information fed back to Lin Yu's mind: this axe is a special magic weapon of the Wu Clan, and this kind of magic weapon is not suitable for cultivators to refine. Because its refining process needs to hurt a lot of living beings, it hurts the heavens and the peace. Once this kind of witchcraft is successfully refined, it can allow the refiner to hide in the witchcraft to avoid the way of heaven after the longevity is exhausted, so as to achieve the purpose of prolonging life......

Through the information fed back to him by the farming system, Lin Yu finally had a better understanding of the black fog in the underground palace. It turns out that there is nothing wrong with the black mist being the primordial god of the witch clan, but this kind of primordial god has already used some kind of witch secret method to refine the witch weapon together. Therefore, this kind of primordial god is different from the normal primordial god, and it is actually similar to the instrument spirit of a witchcraft.

After the normal creatures are exhausted, the original gods will lose their original memories and disappear between heaven and earth, waiting for reincarnation.

Some evil people in the witch clan have created such a secret technique, which can temporarily store their original gods in witchcraft, and then find an opportunity to take away other people's bodies, so as to achieve the purpose of rebirth.

Knowing this, Lin Yu couldn't help but feel a chill in his heart. If he hadn't been very cautious before, he had sent a simulated puppet into the palace at the bottom of the lake, I am afraid that he would have really encountered danger.
