After killing the large Hulk, Wu Yi and the others entered the research institute unimpeded, and there were still some biochemical ghosts left in the first floor of the research institute, and there was not much threat to Wu Yi.

Wu Yi and the three of them quickly rushed to the second basement floor of the research institute and walked to a node, where there were many passage entrances, Wu Yi and the doctor had entered passage No. 47, and found the gene enhancement potion type II in it, and also released a large Hulk.

Wu Yi didn't know much about the other passages, only that the Skeleton Three Treasures had entered the twentieth passage in the very center, but they didn't find anything there, and they returned in vain.

"White Shadow, you should know more about this place, last time you wanted to guide me into passage forty-seven." Wu Yi said to Bai Ying.

City Spirit nodded, she said: "At that time, your strength was still very weak, if you enter other passages, it is likely to be dangerous, and the genetic enhancement potions in passage forty-seven will help you a lot, so I want to guide you in, at that time I just wanted to add strength to the humans in Thor City, I didn't expect you to grow up so fast, and in just one week, you will become a being who can fight against top biochemical ghosts." ”

"Now, which passage should we enter?" Wu Yi asked.

"Go to the eleventh passage, deep in each passage here is a real yàn room, and the eleventh passage is the place where Nolen Company makes the beast biochemical ghost real yàn, where there is the beast type improvement gene potion you want, but this passage is also one of the most dangerous passages, you should be careful." White Shadow said, pointing to a passage to the right.

Wu Yi took the lead and walked in. As soon as he walked into the eleventh passage, Wu Yi smelled a pungent and fishy smell, and at the entrance of the passage there was a researcher's corpse, the flesh and blood on the corpse had rotted, and the smell of the corpse was quite pungent, but this corpse had been dead for more than a month, and the blood stains that flowed out had condensed into black spots.

The researcher was about to walk out of the passage when he was pounced on from behind by a large monster, and his entire lower body was devoured by the monster, and the remaining upper half of his body struggled to escape, dragging a bloody trail on the ground. It can be seen that his will to survive is strong.

And the cyborg monster that chased him seemed to let him crawl outside with the idea of catching a cat and mouse. Then kill him just as he was about to crawl out of the passage, a piercing blood hole in the back of his head was his fatal wound, it seemed that the biochemical monster that killed him had a very sharp weapon, Wu Yi could even imagine the scene of the researcher being crucified to the ground.

Wu Yi did not stay here for long. He led the two girls to the depths of the passage. Passage 11 is quite spacious. There were enough large trucks to drive side by side, and the further they went, the wider they became, and they ended up in a huge solid room. This room is like a forest, and there are many trees planted in it, and these trees are growing luxuriantly, and they are not affected by the cataclysm at all.

There is an artificial light source above the room, which emits a soft light, bringing light and heat to the plants deep underground, so that the trees in the room can grow healthily.

It's really hard to imagine that there is such a vast forest in the underground research institute that is hundreds of meters underground, which makes it difficult for Wu Yi to imagine how big the research institute is, I am afraid that the Valkyrie Research Institute is already equivalent to an underground city.

It can be seen that the strength of Nolan Company can build such a research institute under Thor City without most of the citizens of Thor City knowing, and it has been operating normally for more than ten years, which can be said to be covering the sky in Thor City.

Stepping on the soft soil and smelling the fragrance of the earth, Wu Yi felt as if he had returned to nature, and the forest was also full of upgrades, making the fierce viper vine very active.

"Go inside, deep in the forest is the core area of the real yàn room, where some beast-type improvement genetic potions are preserved, but with the current situation, it is not easy to get there." White Shadow said.

"Well, these biochemical monsters seem to be completely different from the biochemical ghosts we encountered before." Wu Yi said.

Along the way, Wu Yi saw a lot of corpses, all of them were the corpses of the researchers, almost all of these researchers were shot in the head and died, many of them were headless corpses, because the brain was severely damaged, and the ghost virus in the corpse could not make them 'resurrect' and become the walking dead.

Moreover, Wu Yi did not find the body of a single biochemical monster, it seems that there was a one-sided massacre at that time, as a result, the researchers were slaughtered, and all the biochemical monsters in this real room escaped.

Just when Wu Yi and the others walked past a big tree, a dark green vine wrapped around the big tree slowly opened a pair of eyes shining with cold light, looking at Wu Yi under the tree, its eyes became more and more ruthless, and its body gradually slidied, quietly waiting for the best sneak attack opportunity.

This is a highly venomous snake demon, it was originally a tropical viper, captured by Nolen Corporation for biochemical realization, and was transformed into an infinitely powerful and poisonous monster, which can easily camouflage on trees, and then launch a sneak attack that is difficult to prevent.

But it wanted to be a hunter but became the prey in the eyes of others, and before it could attack Wu Yi, a green figure shot out from the trunk of the tree, twisting in the air and quickly pounced on it, and the fangs pierced deep into its body, and it was the fierce poisonous snake vine that suddenly attacked it.

Seeing the fierce viper vine that is larger than its own body, this poisonous snake demon has a cowardice in his heart, there are many existential beings in this forest that it can't provoke, it has become accustomed to surviving with its tail between its legs, and seeing that it is not the opponent of the fierce viper vine, it immediately went downstairs from the big tree and got into the grass to escape.

But the speed of the fierce poisonous snake vine was faster than it, and it launched a snake-like pounce, biting it on its body, and its body whipped it, making it instantly drenched in blood and suffering a lot of injuries.

Seeing that the fierce poisonous snake vine was about to be wiped out, this poisonous snake demon was aroused to die, and the fierce poisonous snake vine tore and bitten, and did not sit still.

Two huge pythons were fighting fiercely in the grass, and Wu Yi stepped forward and slashed hard. Very accurately slashed on the seven inches of the poisonous snake demon, the already scarred snake demon was cut in two on the spot, the body was twisted for a while, and finally stopped jumping, a large amount of blood flowed out of the corpse, and the smell of blood was far away.

Smelling this smell of blood, Wu Yi was shocked, the biochemical monsters in this real room are all modified from beasts, and all of them have a very sensitive sense of smell, I am afraid that this smell of blood will attract many biochemical monsters.

Wu Yigang was about to take the two girls out of here. A few vines whipped through the grass. Coming straight to Wu Yi, Yue'er and Yang Qinghui also became the targets of this vine tentacle, only Bai Ying stood in place, and the other party did not have any intention of attacking her.

The dragon horn sword qi in Wu Yi's hand was rampant. A single sword severed all these rolled tentacles. Make it splash with pale green juice. The other party was slashed, and the tentacles that were originally rolling towards the corpse of the snake demon all slapped at Wu Yi in retaliation, densely covering the sky and the sun. Wu Yi's surroundings were all surrounded by these vine tentacles.

Wu Yi finally saw the other party's body this time, this is the vine on the body of a huge tree, it is a genius-level tentacle ghost, awakened by the smell of blood, and wants to win the rare blood food.

In the face of countless vine tentacles, Wu Yi just swept away, and the arc-shaped sword qi cut off all the tentacles in front of him, and then in this gap, he rushed forward with a swift step, stabbing the body of the tentacle ghost, and the next few swordsmanship killed this huge monster.

It's really devastating, even a powerful soul beast can't use its tentacles to get Wu Yi, let alone this tentacle ghost.

As soon as he killed the tentacle ghost, a black shadow pounced towards Wu Yi, it was a wolfdog-like monster, its size was huge, larger than an ordinary ghost wolf, its skin was a faint earthy yellow, and its teeth flashed with a sharp cold light, and it could tear off a large piece of the enemy's flesh and blood with a single bite, and its aggression was several times stronger than that of an ordinary wolf dog.

Wu Yi didn't look at it, and turned around with a punch, this punch was an instantaneous ordinary nail fist, only to see that the abdomen of this ghost wolf showed a whirlpool-like scar, the wound was torn open, it spat blood and was knocked away, and after landing on the ground, the body twisted again, and the bones of the whole body were shattered, lying on the ground unable to move.

More ghost wolves appeared from the forest and surrounded Wu Yi and the others, Wu Yi, Yang Qinghui, and Yue'er were back to back, holding up the guns in their hands to form a dense firepower network, making these ghost wolves who came in groups suffer heavy losses, and they couldn't get close to the three of them at the cost of half of the members' deaths.

After weighing the pros and cons, these ghost wolves could only retreat in a hurry, not daring to attack Wu Yi and the others again.

But the movement in the forest is not over yet, and the strong smell of blood here has attracted a lot of biochemical ghosts, all of which are biochemical monsters transformed from wild beasts, they are stronger than humanoid biochemical ghosts, extremely aggressive, and responsive, generally elusive, or the skin is so thick that bullets can't move.

After the appearance of a biochemical bear, the other biochemical ghosts scattered, this monster is one of the overlords of the forest, taller and stronger than the large Hulk, I am afraid that it weighs more than a dozen tons, the tonnage is so terrifying, it runs like a rampaging heavy tank.

And the surface of this black storm bear is covered with a layer of biochemical armor, which has a strong resistance to long-range attacks, Yue'er saw that it rushed to the front of him, and hurriedly flashed the black and white stars together, and the incandescent bullet and the black devouring bomb were shot out at the same time, and the huge strong light made the storm bear blind, and hit the big tree headlong in the chaos.

The big tree was almost uprooted by it, the trunk was broken from it, and it collapsed with a bang, and the violent bear himself was a little dizzy, Wu Yi took the opportunity to punch three times in a row, and the biochemical armor on its back was cracked, revealing the flesh and skin on its back.

Wu Yi turned on the Demon Slayer Warrior, put the muzzle of the gun against its back, and poured dozens of bullets at it, without the protection of the biochemical armor, the Biochemical Storm Bear could not withstand the terrible destructive power of the Demon Slayer Warrior, and the inside of the body was almost smashed by bullets, and the attached flames made its skin and flesh all scorched.

The biochemical bear roared angrily, and the huge bear paw slapped at Wu Yi, and Wu Yi hit it with a heavy slash, cutting off half of its bear paw.

Wu Yi's next thrust made a hole in its abdomen, and a large crack appeared in the biochemical armor, and then it was completely cracked by Yang Qinghui and Yue'er with bullets, and the blood volume was reduced to zero under the firearm's fire, and he fell to the ground on his back.

Standing next to the corpse of the biochemical storm, a sharp blood-red tubular object stabbed at the back of Wu Yi's head, trying to shoot Wu Yi in the head, if you look closely, you can see that this is a tongue full of barbs, and the tip of the red tongue is sharper than some sharp weapons.

Wu Yi didn't let his guard down, he suddenly turned around when he was about to be hit, deflected his body slightly, and still didn't completely dodge this sneak attack, that tongue shot on his left shoulder, and all the blood that flowed out was absorbed by that red tongue, making it look even more bewitching.

When the other party wanted to withdraw the long tongue, Wu Yi's right hand grabbed the tongue tightly, and the power of more than two hundred points suddenly exploded, Wu Yi pulled it violently, and the other party was pulled out and fell hard in front of Wu Yi.

It is a monster covered in dense scales, its body is streamlined, toned without being bloated, it has both strength and speed, and its limbs are very well developed, allowing it to stand up and run on all fours.

Its head was small compared to its body, but it had wisdom far beyond that of ordinary beasts, and its tongue, which contracted freely like a spear, was being held in Wu Yi's hand, so it could only tilt its head, and some blood spilled from its mouth.

It has a slender and muscular tail, which can not only maintain balance in high-speed movement, but also serve as a killer weapon at critical moments, pumping it on a person can smash its whole body to pieces, and now it is lying on the ground, and its tail is gently waddling.

Notes: When Nolen Corporation was researching the biochemical ghosts of beasts, they tried to combine the genes of various beasts to develop a new type of species that was the best hunter lurking in the shadows, and when it attacked, it would not give the enemy any chance to react. They are socially accustomed and prefer to attack their prey in groups, making them the top of the food chain.

These xenomorph ghosts dominate the forest, and the researchers in the real yàn room are also slaughtered by them, and they like to suck the brain marrow of people with their long tongues, causing the researchers to die in a terrible state of death. (To be continued.) )
