Yun Feiyu's attention was always looking ahead, and he didn't notice the liquid that suddenly appeared behind the side at all.

At the moment of crisis, Shi Yu didn't have time to think about it, he took a step forward, and slapped the liquid with the long knife in his hand.

"Smack......

There was a crisp sound, and under the action of the force, the moment the long knife came into contact with the liquid, the liquid spread out in all directions and shot out in all directions.

"Laha ......"

One of the drops landed on Shi Yu's left arm, and like sulfuric acid, it began to corrode Shi Yu's left arm rapidly, and made a terrifying sizzling sound.

"Ah......h

The pain rushed to Shi Yu's brain like a tide, making him grit his teeth and roar to resist the pain of the corroded flesh and blood.

Looking at Shi Yu's left arm, the green liquid actually corroded his left arm into a small hole, the thickness of a finger, and the drop of liquid flowed into Shi Yu's arm along the small hole.

Without giving Shi Yu the slightest time to adapt, the attack was rising, only to see that there was no sound, and in the void, a long pink strip-like object with the thickness of an arm suddenly flew out and went straight to the injured Shi Yu.

Before Shi Yu could react, the thing had already arrived in front of him.

Yun Feiyu looked at this scene, drew his knife and stepped forward, and the long knife in his hand slashed out obliquely from bottom to top.

In the moonlight, the blade was cold, and with a single slash, it directly cut the long strip-shaped object into two sections.

At the fracture, a large amount of green liquid sprayed out, splashing in all directions like a shower, like a small rain.

However, this corrosive liquid was deadly, and a single drop had already made Shi Yu miserable, and at this moment, so much liquid was falling, the result could be imagined.

"Talent blooms."

But in the face of such a situation, Yun Feiyu did not panic, snorted coldly, and the ability was activated, only to see the soles of the feet of the two people cracking rapidly, and the vines with the thickness of an arm broke through the ground, and quickly intertwined above the heads of the two, and in the blink of an eye, a large umbrella composed of vines appeared above the heads of the two.

The tick-tock sound continued, and all the green liquid was blocked by the big umbrella, and not a drop fell on the two of them.

At this moment, the big umbrella was already billowing with light smoke, and the liquid kept corroding the vines, making that scalp-numbing snorting sound.

"Roaring ......"

There was a roar, and the ghostly thing seemed to be angry.

There was no sound, a sonic boom, something huge approaching them at great speed.

Without waiting to figure out what it was, Shi Yu only felt a huge force hit him, and directly blasted him and Yun Feiyu out.

The moment he flew out, Shi Yu gritted his teeth and slashed out with all his might.

This knife slashed at a huge hard object, and the long knife was directly knocked out.

But the knife was not useless, it still slashed the strange thing, but the wound was minimal.

"Bang ......"

Shi Yu, who was blown away, fell into the blood, and the black-red blood splashed everywhere, staining the two of them.

Looking at the body covered with black and red blood, and pulling a long silk thread dripping down, smelling the pungent smell of blood, Shi Yu almost vomited.

But at this moment, obviously not caring about this, the strange thing is still hiding in the shadows, waiting for an opportunity to move, obviously, if you don't kill them, you won't give up.

"It's so weird, we can't see it." Yun Feiyu quickly got up, holding the long knife upside down in his right hand, and looked around vigilantly.

"If you can see it, are you sure you can kill it?" Shi Yu spoke quickly and asked.

Yun Feiyu nodded. "You can give it a try, but the key is that this thing seems to be invisible, and we don't even know where it is, how to fight."

Shi Yu spoke quickly and spoke. "I might have a way, give me a minute."

Wiping a handful of blood stains on his eyes, Shi Yu's eyes quickly scanned the surroundings, and when he saw the corpse of a monster, his eyes suddenly lit up.

There was nothing but the corpse of the monster, but if you looked closely, you could see that there was a bright red wound the length of a finger in the void, and blood was constantly flowing out of the wound and dripping downward.

This was the wound that Shi Yu had slashed with all his might, and now this wound had appeared, and it had become a guiding light for them to show them the way.

"There, it's there." Shi Yu pointed to the wound and reminded Yun Feiyu. "Obviously, although this thing can be invisible, there are limitations, and there are some things that it can't make invisible."

"Like the green liquid that dripped from before, and the wounds, the blood, and the long pink strips."

"I guess it's not stealth, it's fusion, like a chameleon, it can blend with its surroundings to hide itself."

"It's just that this thing is much more powerful than a chameleon, and it can completely integrate the environment and hide itself perfectly."

"The reason why chameleons can hide is that they rely on the surface of the skin to change pigment and adjust the color to achieve the effect of being fake."

"That wound is proof that the skin there has been cut by a long knife and can no longer melt into the environment."

Shi Yu's words made Yun Feiyu's eyes light up. "You're very smart, and I'm a little impressed with you."

Yun Feiyu said, the long knife in his hand was raised, the knife pointed to the void, and continued. "I know about what this thing is, the rotting bone monitor lizard, evolved from a chameleon, although it is huge, it can perfectly blend with the environment, and the saliva in its mouth has a powerful corrosive ability, and its corrosive effect is a hundred times better than that of sulfuric acid."

"It's said that this thing has evolved to appear in pairs, but now it seems to be the only one here, which makes it a lot easier for us."

The energy on the long knife was swirling, like an invisible firework rising and burning in the long knife, holding the long knife, Yun Feiyu's body shot out like a sharp arrow, heading straight for the monitor lizard.

"Since you're showing up, let's stay here."

With a soft snort, the Yunfei fish had not even reached the monitor lizard's body before the ability was activated.

I saw dozens of vines break through the ground and entangle towards the bloodstain, and at the same time, several vines continued to stir in the blood, stirring the blood into the air, and when the blood fell, it was like a rainstorm, overwhelming.

The monitor lizard could not dodge at all, and was drenched in blood, so that its perfect camouflage was useless, and it was exposed to the square.

The monitor lizard's tail flicked, streaked through the air, and whined at the vines that broke through the ground.

The tail of the monitor lizard seems to be made of steel and iron, and the moment it hits the vine, the vines are shattered, and the green leaves and rhizomes are splashed in all directions, flying away.

Yunfei fish shuttled through the green leaves of the sky like a sharp arrow, his eyes were cold, and the long knife in his hand was full of energy, piercing the eyes of the monitor lizard.

The Yunfei fish was extremely fast, and the monitor lizard that had just launched an attack had no time to react, and could only watch as the tip of the knife flashed with sharp edges, easily tearing its skin and piercing into the eyeballs.

"Poof......

The muffled sound of the blade entering the flesh sounded, and blood splashed everywhere, making the already blood-stained Yunfei fish even more bloody, and completely turned into a bloody person.
