A few minutes later, Cheng Xin finally made a stunning appearance, wearing a set of tight-fitting tactical uniforms, showing a hot figure, this kind of figure is not a backbone or plump, it is a well-proportioned beauty that can only be found in regular exercise, wearing a dark black non-reflective "Kevlar" special helmet on his head, two crossed knives on his back, a special rifle hanging obliquely on his chest, 6 grenades hanging on his waist, two dark sabers on his calves, and all the equipment on his body is completely beyond the standard configuration of a base, Transform into a well-trained beauty warrior.

Judging from the doctor in the white coat just now, the current Dr. Cheng is heroic, with a solemn face, his glasses have been removed, and his eyes are full of sharpness, looking like a female warrior who often trains.

"Dr. Cheng, it turns out that you are not short-sighted." Li Xiangling, who is also a beautiful female warrior, asked when she saw Cheng Xin's weak dress, Cheng Xin's stunning appearance stunned everyone, except for Ouyang Shaoyu, the rest of them were full of incredulity.

"Wearing glasses is just to prevent the splash of bodily fluids when dissecting monsters." Cheng Xin smiled faintly at Li Xiangling, then looked at everyone and said, "Wait a minute, don't worry about me." ”

The corners of Chen Zhidong's mouth twitched a few times, he wanted to say something but he still held back, and just waved his big hand: "Let's go." ”

Then everyone left the laboratory one after another and walked towards the underground hall, just when Li Li was about to go out, Cheng Xin inadvertently pulled the corner of his clothes, Li Li looked back at Cheng Xin suspiciously, and found that she smiled mysteriously, Li Li understood that he subconsciously slowed down a few steps.

"Take out the crystals of this humanoid monster, I know you need it, so take it as a greeting gift!" Cheng Xin handed Li an ordinary-looking dagger and pointed at the humanoid monster lying on the test bed.

Li Li subconsciously took the dagger, his face sank, and a huge wave suddenly set off in his heart, he had a feeling that he was actually seen through by this woman, as if he was transparent in front of this woman, and there was no secret to speak of.

"This knife is very sharp, it is made of nanomaterials, and don't cut the tube inserted into the monster's body when taking out the crystals, otherwise the monster will wake up soon, and it will be troublesome, and I feel that something is wrong with your body." Cheng Xin ignored Li Li's gloomy expression, finished his words in one breath, and then walked directly to the front.

When he heard Cheng Xin's last sentence, Li Li's head "buzzed", and he looked at Cheng Xin's back incredibly, and he was even more curious about this woman in his heart, and he faintly felt that the answer to the stinging head was in this woman.

Li Li didn't hesitate, took the dagger and quickly came to the side of the human monster, unceremoniously inserted the dagger into the monster's head, to Li Li's expectation, the dagger was easily inserted into the monster's head, carefully put his hand into the monster's head and took out the crystal, and a light red crystal the size of a pigeon's egg appeared in the palm of his hand.

Looking at this dagger that easily cut the head of the humanoid monster, Li Li was overjoyed, with such a sharp dagger, it would be no problem to meet a mature long-tongued reptilian beast, and then carefully put the dagger away, and he was also quite curious about this Dr. Cheng in his heart, this dagger is really worthy of sharpening iron like clay, although the strength of the humanoid monster's body is not as good as steel, but it is difficult for ordinary daggers to pierce it.

Li Li held the crystal in his hand, unceremoniously, his mind moved, and the light red crystal quickly melted into the palm of his hand, after reaching the fourth order, he could already use his mind to control the opening of the devouring ability, and it was also helpless to choose to devour and upgrade here, after all, in the face of powerful monsters next, one more strength before breaking through is one more capital to live, maybe Cheng Xin also plans to do the same, hoping to have one more strong team member.

A few minutes later, Li Li walked out of the laboratory in high spirits, and soon caught up with Chen Zhidong and the others, Cheng Xin glanced at Li Li, Li Li nodded at her with a smile and stretched out five fingers to indicate that he had become a fifth-order ability, and the two looked at each other and smiled without speaking.

Chen Zhidong and his entourage walked out of the underground corridor and came to the last steel gate, everyone was instantly wrapped in gray mist, and the atmosphere suddenly became tense, Li Li slowly sent out his spiritual power to scan the surrounding environment, and after becoming a fifth-order ability, the diameter of the spiritual power scanning can already reach 5 kilometers, and the one-way extended scanning is no longer easy to visually detect, at least ten kilometers.

Chen Zhidong took out the night vision goggles and observed the surrounding environment, and with a wave of his hand, the Thunder Squad protected Cheng Xin in the center in a combat formation, and slowly approached the place where the personnel carrier was parked.

The troop carrier quickly started and returned to the route where it came, everyone was very vigilant along the way, and Li Li also released his spiritual power to warn, with his current fifth-order strength, as long as he didn't encounter too powerful monsters, he was confident to fight, even if he met the humanoid monster in Yunxian County again, he would not be powerless to fight back, and he had the power to fight.

"It's not good, there's a situation ahead, stop quickly." Li Li's complexion changed greatly, and through the scan of spiritual power, he clearly saw that a giant worm beast more than ten meters long was rapidly approaching the convoy dozens of meters underground, and countless dirt on the ground turned around, obviously this giant worm beast was coming from the ground.

The bangs who were driving subconsciously stepped on the brakes, and the troop carrier stopped with a creak, and at the same time, a few meters in front of the troop carrier suddenly shook, and a giant worm beast more than ten meters long suddenly jumped up from the ground, opened its big mouth and prepared to spray strong acid into the troop carrier for corrosion.

"Bang!" There was a slight muffled sound, a bullet that emitted cold air instantly hit the giant worm's open mouth, and swallowed back the acidic liquid that was about to squirt out, just as the giant worm was in pain and closed its mouth, Chen Zhidong shot at the giant worm like lightning at the same time, and when he approached the giant worm, Chen Zhidong's right hand suddenly shot out a white sensen's bone spear, which instantly pierced the head of the giant worm, and the giant worm screamed and slowly fell.

Seeing the two of them kill a giant worm beast in the blink of an eye, Li Li secretly admired in his heart, this adaptability and seamless cooperation really deserve to be the most elite special forces.

Chen Zhidong returned to the troop carrier, frowned and said, "Hurry up, this roar has attracted a lot of monsters." ”

As if to prove what he just said, there were bursts of roars around him, and Liu Hai did not hesitate to increase the speed of the troop carrier to the fastest instantly, and the roar gradually became clear, this roar made people shudder in the gray space, like a ghost crying wolf.

"Oh no, there's an alien monster rushing here from behind." Li Li's brows furrowed, and through the mental power scan, he could see that it was the semi-mature alien monster that was attracted away by the roar in the research institute, jumped high and then used the dark wings behind him to make a short glide, chasing after the troop carrier at a very fast speed.

Ouyang Shaoyu was still expressionless and gathered his rifle to aim at the car, and in a few breaths, the alien monster had already chased a distance of dozens of meters from the personnel carrier, and as long as he jumped up and glided again, he could catch up with the personnel carrier.

"Bang!" With a slight muffled sound, a cold bullet shot at the alien monster gliding in the air, only to see that the bullet was blocked by a faint circle of light at a distance of half a meter away from the alien monster, and the bullet finally penetrated the protective shield and hit the alien monster but the power has been greatly reduced, and even the dark cuticle of the alien monster did not penetrate and fell.

Although this bullet did not cause substantial damage to the alien monster, it also successfully hindered the pursuit of the alien monster, and once again opened a little distance, just when everyone was relieved, a large group of soldiers suddenly appeared in front of the personnel carrier, yes, a large group of human soldiers.

Li Li immediately found that these soldiers had dull expressions through the mental power scan, and they were just mechanically surrounding the personnel carrier, seeing the expressions of these soldiers, he suddenly remembered the puppet that Gao Jun called "General" that he had seen in Yunxian County, and he was terrified when he saw so many puppets.
