Xie Xuan is not a person who likes to judge people by their appearance, but to be honest, Dr. Song does not look like the most powerful ultimate boss now.

Doctor Song looked at Xie Xuan with his equally cloudy eyes. When he passed between the experimental subjects, the experimental subjects on both sides fell down one after another as if the bacteria had been absorbed by them.

Xie Xuan was not anxious at this time, because the liquid flowing out of the container probably also had an inhibitory effect on Dr. Song, and now the liquid was flowing rapidly to an unknown place.

The last bit of suppression completely disappeared. When Dr. Song walked in front of all the experimental subjects, Xie Xuan quickly closed the distance between them without any nonsense.

Dr. Song was obviously a typical scientific researcher. His only reaction to Xie Xuan's sudden approach was to try to mobilize his newly acquired superpowers.

But his speed was far slower than Xie Xuan's knife. When Dr. Song just raised his hand, Xie Xuan's knife had already cut off his head.

The villain Dr. Song didn't even have a chance to die because of his talkativeness. He was beheaded by Xie Xuan as soon as he appeared.

The severed head rolled around on the still wet ground, but Dr. Song's body remained standing and did not fall down.

The same yellow-green liquid as in the previous experimental subject did not flow out from the fracture. Instead, it began to wriggle and sprout flesh buds like a monster in a horror movie.

Xie Xuan's superpower immediately enveloped the rest of Dr. Song's body, but his body had a similar nature to the previous experimental subject, and it absorbed the superpower very slowly.

In just a few seconds, the granulation tissue at the wound on Dr. Song's neck began to wriggle rapidly, and then, like a carbonated drink that was shaken excessively and then suddenly opened, the gray-black unknown substance inside gushed out from the incision.

A true monster was born.

The gray-black spider-like monster that emerged from Dr. Song's body was three or four meters long. As soon as it came out, it stuck to the ceiling.

Dr. Song, who was left behind, turned into a shriveled body and fell to the ground.

Xie Xuan didn't have time to laugh at Dr. Song because the big spider above her head spit a ball of spider silk directly at her.

She immediately dodged to the side, and gray-black spider silk fell to the ground. It looked like the floor, which was made of some extremely strong anti-infection material, had been corroded and left a mark.

The black shadow completely emerged from Xie Xuan's shadow and turned into a giant who was also three or four meters tall and pounced on the spider.

But although the spider and the shadow were about the same size, the spider was much more agile. It moved in the huge room so fast that Xie Xuan could only see a black shadow.

Xie Xuan's speed is not as fast as a spider, but fortunately she has enough special abilities.

The black shadow giant became as tall as Xie Xuan again, but the shadows under their feet quickly spread throughout the room, not only the ground, but also the walls and ceiling.

While the shadows were oppressing the spiders' space to move, the spiders were also constantly spitting silk towards them.

Dense spider silk fell like rain, and Xie Xuan had nowhere to hide.

Spider silk is not entirely made of life force. Shadow dealt with it like using a bamboo sieve to block rain. Xie Xuan had to use white mycelium to resist the attack of the spider silk.

After a brief battle of attrition, the spider was captured by the shadow without any surprise.

After being entangled by the shadow, the spider's speed slowed down a lot, and the shadow quickly climbed up its body, while the spider struggled and spun silk frantically.

Xie Xuan directly controlled the dagger and split the spider in half.

The dagger easily cut the spider wrapped in black shadow into two halves, but Xie Xuan soon found something wrong.

The shadow wrapped around the spider not only did not gain any superpowers from the spider, but was actually getting smaller.

Xie Xuan immediately retracted his shadow. The moment the black shadow disappeared from the spider, countless thumb-sized spiders emerged from the shadow.

This group of spiders pounced on Xie Xuan like a sea of ​​spiders. Xie Xuan quickly covered the spiders that had not yet completely dispersed with a transparent cage.

But the cage was completely eaten up by the spiders in just ten seconds.

These little spiders can actually devour superpowers just like hers, and their devouring ability is even stronger than Xie Xuan's.

Now things became tricky. Xie Xuan didn't expect that Dr. Song could still come up with so many tricks even though he was dead.

Xie Xuan didn't bring a flamethrower when she came out, and an ordinary pistol had no effect on this group of spiders. Xie Xuan could only turn around and run out of the room immediately.

But she didn't have the authority to control the doors, and now all the doors were open, so she had to find a solution as soon as possible.

While Xie Xuan was thinking about a solution, he was looking around for other exits.

But she didn't find the exit, but she saw a very hidden sewer by the wall.

Xie Xuan immediately thought of the transparent liquid just now.

This is underground, and there may be other laboratories above and below. These liquids must have an outlet, and even if there is no outlet, there will be a place to collect them.

Xie Xuan immediately controlled the dagger and began to search for a passage along the sewer.

The spiders behind him also caught up at this time. Xie Xuan did not look back and could only let Shadow stop them.

However, a few spiders still broke through the defense line and drilled onto Xie Xuan's body.

The protective suit couldn't stop them from biting her. Before Xie Xuan could swat them away, they had already bitten off a piece of flesh from her body.

Rather than having the ability to devour, these spiders are more like having teeth that can bite off anything.

The wound healed quickly, and the sewer was about to be fully exposed. At this time, Shadow was also eaten by more and more spiders, and groups of spiders swarmed onto Xie Xuan's body.

Xie Xuan fell into the passage which was just big enough for one person, and she flowed down with the spider.

The spiders were still biting her in every pore in the passage. Her protective suit had been completely eaten away, and even her regeneration speed could not keep up with the speed at which the spiders were eating.

If she shook off the spiders on her body now, she would probably be a bloody mess.

The falling process lasted for about a minute before she finally fell into a pool.

The pool was not deep and the water inside emitted an unpleasant stench. After Xie Xuan fell in, she hit the bottom of the pool.

The familiar feeling of having her superpowers suppressed made Xie Xuan realize that this water was the unknown liquid discharged by Dr. Song.

The spider on Xie Xuan's body died immediately after falling into the water and fell off her body.

Xie Xuan turned around and began to swim upstream, but when she surfaced, she saw an incredible scene.
