After Xiaobai walked into the passage, he did not stop because the stone wall behind him automatically rose to block the passage entrance, and walked towards the depths of the passage on the right without stopping. In the dark passage under the light of this faint firelight, Xiao Bai's green and red eyes looked a little seeping, and if he put on a white scholar's outfit, he would be more like a ghost.

After walking the same distance as Zhang Chen, he came to a circular stone room, but in the center there was a rectangular column, and there was still a circular groove in the middle of the main body.

"Hiss!" Just as Xiaobai looked around, a small black eight-legged spider crawled out of a floor in the corner, Xiaobai was a snake, but he couldn't feel the slightest insect breath on this spider.

The long knife that exuded cold air was held in Xiaobai's right hand, and his eyes were locked on the movements of the small spider.

The black eight-legged spider did not come towards Xiaobai, but crawled towards a dead body whose body was not completely decomposed, and began to spit out a large amount of white spider silk to envelop the dead body, revealing only the half-festered head of the dead body. After the silk was wound, the little black spider crawled directly into the mouth of the dead corpse.

"Not good!" Although the little spider is weird, it doesn't feel dangerous to Xiaobai. However, after the little spider crawled into the mouth of the dead corpse wrapped around the spider silk all over its body, a heavy ghostly aura emanated out, making Xiaobai shudder.

"Poof!" The cold light flickered, and Xiaobai came to the dead body in an instant, and Wangtu cut the corpse with a knife.

But in the next second, after the blade wrapped in fierce qi fell, it actually cut an extremely deep knife mark on the ground, but the corpse was gone.

"So fast!" The corpse disappeared in an instant in the eyes of ordinary people, but Xiaobai's eyes clearly saw that when he split vertically, the corpse wrapped in spider silk instantly dodged and adhered to the top of the stone chamber.

Xiaobai pulled out the Miao knife and quickly retreated, frowning at the dead body on top.

The head of the corpse, which was originally facing upwards and facing the stone wall at the top, made a "click" sound and turned 180 degrees. And in the center of its forehead, a large number of spider-like small eyeballs grew and stared at Xiaobai.

The body of the corpse wrapped in thick spider silk began to move, and there seemed to be something under the white spider silk trying to break free." Smack! With a bang, eight huge hairy spider legs broke through the silk wrap and came out. Insert into the stone wall.

The broken spider silk fell, leaving a monster with a human head and a spider body clinging to the top, looking very infiltrating.

However, Xiaobai was not afraid at all, the corners of his mouth smiled slightly, in his heart, his strength had improved a lot, and he was trying to find a strong enough opponent to try his skills, and the spider monster in front of him just met his requirements.

"Smack!" Xiaobai's back cracked, eight flesh-red tentacles spread out, and thick strips of flesh floated in the air with teeth and claws, and the breath completely overwhelmed the spider monster.

The top two strips of meat suddenly stabilized. Shoot straight towards the spider monster's location.

"Boom!" There were two big holes on the top of the stone wall, but the spider monster had already fallen from the top, and eight long-haired powerful legs were crawling on the ground, coming towards Xiaobai at a very fast speed.

The remaining six strips of flesh all locked onto the fast-moving spider. Shoot out quickly.

This huge spider, the dozens of small eyeballs on its head carefully stared at the Qiē in front of it, and the seemingly huge body moved quickly while also sensitively avoiding Xiaobai's attack similar to a schizon.

"Haha, that's amazing." The big spider dodged all the attacks of the meat strips, and was already close to Xiaobai's face, and the hair on the legs of the eight thick spiders became extremely sharp. And secreted purple venom left along the tip of the hair, and pounced on Xiaobai.

"Click!" As soon as the cold light appeared, when the spider monster was about to succeed, its huge body directly turned into two halves, purple venom splashed, and when a drop fell on the ground, it actually corroded a small hole deep in the group.

However, when a large amount of venom splashed on Xiaobai's body. Nothing out of the ordinary happened, it was like water on the body. Xiaobai stretched out his tongue and licked a drop of purple venom on his face, and said a little after tasting it

"This venom is of a terrible grade."

After the spider monster that was cut in two fell to the ground, its aura seemed to weaken only a little. However, a large number of small black spiders began to pour out from its body, and the original human-headed spider body and torso deflated. Most of those little black spiders tried to attack Xiaobai in vain. At the same time, a small number of people crawled towards the corpses of the circular stone chamber.

Xiao Bai frowned, the tip of the knife slashed, and an ice curtain blocked in front of him, temporarily blocking the tide-like black spider. The figure flashed back, and the whole person was prostrate on the wall of the stone chamber behind him.

"Ten thousand snakes, out!"

Xiaobai's chin was elongated, and from his mouth, sleeves, and trousers, a large number of poisonous snakes swarmed, and the number could be said to be in the thousands. In the face of this tide of poisonous snakes, those large bunch of small black spiders are not worth mentioning at all.

The poisonous snake and the spider bite together, and Xiaobai, who has assimilated with the sniper, is also affected. A small wound from a spider's bite is not worth mentioning at all, and even after being broken into two parts, it can survive as a two-stage organism alone.

Gradually, the tide of poisonous snakes receded, and all of them returned to Xiaobai's body. Xiaobai patted the dust on his body and walked to the location of the human-headed spider before. The corpse, broken in two, was gone, leaving only a delicate skull to fall to the ground.

Xiaobai stretched out his arm, leaned down to pick up the skull, held it in the palm of his hand, looked it left and right twice, and then turned his head. [,！ Looking at the long column in the middle, the groove in the center of the main body seemed to be just big enough to accommodate the skull.

"Zhang Chen, that guy is really slow, hasn't he done it yet, I don't know what kind of thing he has encountered."

…………

In a square stone chamber opposite the round stone chamber where Xiaobai is

Zhang Chen crossed his hands on his chest, staring at the palm-sized blood spirit slowly floating towards the disgusting-eyed monster in the corner that was devouring Zhang Chen's mental power.

The eyed monster seemed to notice the approach of the blood spirit, and turned around and turned to the blood spirit floating in the air, and there seemed to be a little horror in its eyes.

"Is the Blood Spirit talking to it?" Zhang Chen saw that in the process of looking at each other, the disgusting monster's eyes kept changing their expressions, some were frightened, some were strange, and some were angry.

A minute passed, and Zhang Chen's face changed. Muttered: "It seems that the talk has collapsed."

In the eyes of the monster, the blood spirit seemed to be a very formidable opponent, so it no longer maintained its human form, and shot countless tiny branches from the green slime-like body, heading towards the blood spirit.

However, the blood spirit floating in the air doesn't seem to have the intention of dodging. Let the branches of the green corrosive liquid penetrate their own spirits.

"If it can corrode my mental power, I'm afraid it can corrode even if the blood spirit is a spirit body. I don't know what the hell the Blood Spirit wants to do." Zhang Chen had already stretched out his claws, and as long as the blood spirit showed a slight discomfort, he would immediately make a move.

The mutation occurred, and the corrosive branches inserted into the blood spirit's body began to slowly turn red, and quickly reversed in the opposite direction of the branches.

The disgusting monster's IQ was indeed a little low, and it was unmoved to see the branch it had split out from being turned into the color of blood, until the blood red spread above its body, and the monster let out a "whoop" wail.

The green slime body began to be eroded by red, and the eyes on the blood-red body quickly became bloodshot and exploded.

"This blood spirit really has two hits. It seems that I don't need to do it, and I can still get benefits."

When the monster's whole body was occupied by bright red to two-thirds, the blood spirit itself flew into the monster's body, and the blood spread faster, and all the eyes exploded at the same time. The monster's body collapsed inward, merging into the body of the blood spirit. As in the white room, a skull falls to the ground.

"Master, come and take me into your body." The blood spirit hurriedly spoke.

Zhang Chen also saw the strangeness of the blood spirit, and quickly came to the side of the blood spirit in one step, and retracted it into his right chest.

"This thing is from the Bloodline, and it's mutated. The transformed blood energy is extremely large and ready to be absorbed. Just now I used the source power to fuse with the monster's mutated energy, and I may need to rest for a while, and please don't wake me up during this time."

"No problem." After Zhang Chen agreed, he immediately sensed a large stream of blood escaping from his right chest.

"What a majestic blood energy." Zhang Chen mobilized all the cells in his body and absorbed all these blood energy. Not only repairs the injuries on the body and fills the energy consumed. And the fourth drop of essence blood is formed.

Feeling the blood spirit with his eyes closed in his right chest and his breath fluctuating in strength and weakness, he smiled slightly at the corner of his mouth, presumably after this blood spirit opened his eyes, his strength would probably improve a lot. Then he leaned down and picked up the delicate skull that had fallen to the ground and had not been absorbed by the blood spirit.

"That's the key, right?" See the size of the skull. Zhang Chen immediately corresponded to the groove in the center of the circular cylinder.

"Xiaobai." Zhang Chen tried to sense the transmission.

"Huh? Zhang Chen, you're too slow, I've been idle for a long time." Xiaobai's voice sounded in Zhang Chen's head.

"Haha, after a little delay, you should have also got the key to open the mechanism, right?"

"Well, it's just a skull."

"That's it, I'll count three times and we'll turn the switch on at the same time. Ready, three, two, one."

After Zhang Chen finished transmitting the sound, he put the skull into the circular groove at the same time as Xiaobai.

"Click!" After the skull was placed in it, the pillar rotated twice and slowly sank into the ground, and the entrance to the passage behind Zhang Chen, which was sealed by the stone wall, also slowly opened.

After Zhang Chenyuan Road was put back and met Xiaobai in front of the stone monument at the entrance, the two passages on the left and right were closed by the stone wall again. And the stone monument in front of the two of them automatically sank into the ground.

I thought a stone door would be opened, but in fact, a square passage opened at the stone tablet that had sunk into the ground, revealing a small corridor that extended into the dark underground.

"Huh? And go down......"
