"Whew!"

Bone Poison's poisonous skill attack directly tore the skin and flesh of the Taibai Snake, and the wound was deep and the bones were visible. The Taibai Snake let out an angry roar when it was injured, and the wound was filled with fishy snake blood.

No matter how hard the white snake tried, it couldn't entangle the cunning human in front of it and strangle the human who injured it. If it bites it, the poison will instantly invade the body of the bone poison, destroying the nerves of the latter and incapacitating it.

Seeing this, the bone poison seemed to have already had a countermeasure, and his figure flashed, avoiding the attack of the Taibai Snake. In his hand was a strange weapon, which was split into three crescent blades, with a faint blue sheen on them, apparently quenched with poison.

This weapon is very vicious, and ordinary people will be poisoned to death as long as they are lightly scratched. The Taibai snake itself has a certain resistance to toxins, so it will not die immediately.

However, now it is also uncomfortable. The constant sensation of paralysis on its body made it move more and more slowly, and its strength was gradually decreasing.

At this time, the bone poison that grasped the opportunity will naturally not let go. He would rather go down and chase Sun Xiaofei for the time being, staying just to kill this Taibai snake and obtain the materials and venom on its body.

"Boom!"

The bone venom dodged below the Taibai Snake, aimed at the seven-inch part of the Taibai Snake and stabbed into it fiercely, and the Mitsubishi blade stirred wildly, almost penetrating that part.

The Taibai Snake received a fatal blow from the bone venom, and after tossing for a long time, it finally slowly stopped and died. Bone Poison stepped forward to take a look, then moved his hand and said, "Collect!"

The corpse of the Taibai Snake on the ground was completely collected by him into the space ring, and the bone poison discerned the direction of the demon slayer's pursuit, and then a layer of black mist filled the body, and quickly flew there.

It only took less than a minute before and after the bone poison killed the Taibai Snake, which was not enough time for him to catch up with the Demon Slayer and Sun Xiaofei. Moreover, with his strange and changeable body style, his speed in the mountains and forests will not be affected.

Soon, Bone Poison found his location with a hint of induction with the demon slayer.

"Why don't you chase after you?" Seeing the demon slayer wandering among the trees, Bone Venom stepped forward and asked.

"Hmph, that little bastard is gone. The Demon Slayer said coldly.

"What? That kid has the ability to remove the marks you've left behind. Old Devil, your tracking ability has deteriorated? Hearing this, Bone Poison frowned and said.

"Old poison, don't worry. The person who has been marked by me, Lao Tzu knows how to find him. Come with me. After the demon slayer finished speaking, he ignored the bone poison, and as soon as his body moved, he ejected and entered somewhere in the woods.

Bone Poison smiled, and then cast his body technique, turning into a black smoke and following closely.

Using the cover of the formation, as well as the time of the fierce battle between the two demons and the Taibai Snake, Sun Xiaofei successfully erased the mark in Seth's body. Then he attacked the Demon Slayer and lured him to track him down.

Sun Xiaofei had already set up some powerful formations somewhere, preparing to severely damage the Demon Slayer and Bone Poison, so as to avoid falling into an entanglement situation like now.

Sun Xiaofei used a secret method to hide his own breath and hide in the formation. Seth stays in the distance, recovering his stamina and mana. Respond to Sun Xiaofei's actions at any time.

After waiting for a while, Sun Xiaofei saw some unusual movement in the woods in the distance, and a figure full of fierce aura walked out, his eyes were glowing with a miserable white luster, and he was holding a terrifying blood butcher knife, which was the demon slayer.

The demon slayer approached the edge of the formation and carefully observed the surroundings, he could already vaguely sense the breath of Sun Xiaofei and Seth, and he couldn't determine where it was. Moreover, although he couldn't see anything in front of him, it gave him a sense of danger.

The demon slayer groaned for a moment, slowly approaching it, keeping an alert eye on the movements around him. He vaguely felt that Sun Xiaofei might be hiding around here, and now he had to find a way to force him to show up.

"Woohoo!"

As soon as the demon slayer walked into a formation arranged by Sun Xiaofei, he immediately triggered the attack of the formation, and dense attacks shot one after another. The demon slayer dodged in a flash, and before he could break the formation, another formation was triggered, only to see countless vines entwined over, it was a wood-based formation.

The demon slayer took the blood butcher knife and slashed wildly, breaking this wooden formation in one fell swoop. However, this was only the beginning, and the various formations that followed included the sharpness of the gold system, the heaviness of the earth system, the fanaticism of the fire system, and the femininity and coldness of the water system...... Even some of them are intertwined with the power of the eruption, so that the demon slayer has to be careful to resist.

The demon slayer fell into the encirclement of the formation all of a sudden, and the formation designed by Sun Xiaofei was closely linked to each other, as long as one of them was stimulated, it would trigger the attacks of the other formations.

These formations are all high-level formations based on the five elements, and for this reason, Sun Xiaofei has lost a lot of high-level formation materials. Only then can they use the power of the five systems of metal, wood, water, fire, and earth to carry out this kind of uninterrupted intensive attack on the demon slayer with varying degrees.

The demon slayer spent a lot of money before destroying the attack formation that Sun Xiaofei had arranged for him. And at this time, his physical strength also decreased a little, and at the moment when his mental strength was a little negligent, Sun Xiaofei, who had been hiding outside, made a move.

Sun Xiaofei waited for the opportunity for the demon slayer's spirit to relax, and immediately sent out the Sky Sword to attack him.

"Whew!"

The flying speed of the Sky Sword was extremely fast, and as soon as it was issued from Sun Xiaofei's hand, it disappeared in a flash in the air, and the next moment it appeared in front of the Demon Slayer. The sharp sword on the sword body hurts, this kind of attack power, if it is in normal times, the demon slayer naturally does not pay attention to it, but now it is different.

After being consumed by the formation, he could no longer occupy an absolute advantage in terms of strength. The Demon Slayer hurriedly raised the Blood Butcher Knife to defend against the incoming Sky Sword.

"Boom!"

Suddenly, there were bursts of loud noises, and those shock waves formed a circle of invisible ripples that spread out to the surroundings, and any trees, mountains and rocks that were touched by the impact force instantly turned into powder and dissipated between heaven and earth. This head-to-head confrontation between the two has caused such terrible destructive power.

In the billowing dust, the figure of the demon slayer fell out, and Sun Xiaofei also appeared not far away, but the situation of the two of them was not very good, and the impact just now caused both of their bodies to suffer a huge shock, and they have not recovered yet.

Sun Xiaofei endured the pain in his body, and cast the most powerful forbidden technique he had mastered now, pinching the trick with both hands and pointing at the demon slayer, and the mysterious forbidden rune appeared in the air, quickly dissipating into a dazzling light enveloping the demon slayer's body.

The demon slayer was horrified to find that after the light fell on his body, he lost control of his body, and the fighting power in his body was suddenly imprisoned by a powerful and inexplicable force.

"Ryan, I'm here. Die, you demon!"

Suddenly, a figure shot in the distance, and it was Seth. When he came to the scene and saw this, he would not understand what was going on. Remembering the damage he had suffered, his anger swelled, and he immediately unleashed a powerful magical attack on the demon slayer, trying to kill him there.

The Demon Slayer's face changed when he saw Seth's magical attack. Hurriedly and secretly called for help to the bone poison lurking in the middle of nowhere, telling him to hurry up and stop Seth from poisoning him. As long as the bone poison can resist this magic attack in time, he will be able to break through the confinement of Sun Xiaofei's forbidden technique within this time.

"Nether Poison Spear!" The space fluctuated, and the muffled voice of bone poison came slowly, and then it appeared in the treetops not far from them, and dense pitch-black spears flew out, enveloping the place where Sun Xiaofei and Seth were.

When Sun Xiaofei saw this scene, his heart was shocked, on those pitch-black spears, he felt a breath of death, and those pitch-black spears were filled with bursts of foul smell, which were clearly highly poisonous. Once contaminated, immortality will also suffer serious damage.

Sun Xiaofei hurriedly shouted at Seth: "Seth, poisonous, get out of the way!" Sun Xiaofei opened his mouth and spewed out a burst of essence blood vitality, which turned into a layer of dark blue light curtain on the outside of his body, and at the same time, the dragon scale armor also emerged, at this time, he could only try his best to resist. Whether it can resist it depends on the will of God.

Seth heard Sun Xiaofei's warning, and when he saw the Netherworld Poison Spear breaking through the air, he couldn't help but shudder, and he hurriedly summoned a magic defense to protect his body, and tried his best to flee into the distance as fast as possible.

"Snort......!"

Those poisonous spears shot in that area, producing a series of sounds, as long as the things that were shot by the poisonous spears would be corroded in an instant, turning into a pile of turbid liquid, emitting a foul and foul smell, the poison of these Nether Poisonous Spears was so intense.

The demon slayer was not shot by the poisonous spears, as if those poisonous spears had their own consciousness, and they bypassed the place where he was and only attacked Sun Xiaofei and Seth. The demon slayer didn't dare to be careless, but still tried his best to break through the confinement of Sun Xiaofei's forbidden technique, and condensed a pair of fighting armor in his body as a defense.

Sun Xiaofei and Seth struggled to resist the attack of the bone poison, the strength of the bone poison was even stronger than that of the demon slayer, and with just one attack, the defense of the two was about to be directly blown away, and the huge impact made the two almost faint.

Seeing that it had not caused any harm to Sun Xiaofei, the bone poison immediately came down from the tree and shot at the latter at a rapid pace. Looking at his hideous appearance, it is clear that he wants to put Sun Xiaofei to death.

"Who are you, and why are you helping him?" said Seth as he glared at the bone poison.

"Boy, let me die. I'm going to take you back to refine your soul, so that your life is worse than death. Avenge my disciples. The voice of the bone poison yin test sounded in Sun Xiaofei's ears, which made the latter suddenly startled, and finally knew that this terrifying master in front of him was actually his life-seeking Yama.
