After exploring and playing Thunder Tower, there is nothing of value left in the Valkyrie Institute, and Wu Yi's next target is the Biochemical Brood, which should also be the last battle.

In order to ensure the state of the final battle, Wu Yi rested in the Thunder Tower for a short time, and waited until the skills of the Transforming Bear and the Transformation Werewolf were buffered before getting up and leaving the Thunder Tower.

Coming out of the Thunder Tower, Yue'er had a relaxed expression, chatting and laughing with Yang Qinghui, as Wu Yi's apostle, when Wu Yi completed the advancement, she also gained advancement, her attributes and skills were strengthened, plus the previous genetic evolution, she was much stronger than when she entered the research institute.

She also knew very well that after Wu Yi was promoted, her strength had increased a lot, especially after summoning the Ancestor Stone Demon and the Skeleton Archer to evolve, the two summons became Wu Yi's right-hand men.

Yue'er is very optimistic about the action of killing the biochemical brood, and it is the strength of her own side that gives her confidence.

After Wu Yi and the others left the Valkyrie Institute, they stepped into a huge and wide underground passage, which went straight to the area where the Mythical Mansion was located, and the body of the Biochemical Mother Hive was located in the depths of the underground of the Mythical Mansion.

According to Bai Ying, at the end of this passage, there is a flesh and blood pipeline leading to the structure of the biochemical brood, which is the only passage for the biochemical brood to connect with the outside world, but there are definitely many guards there, and Wu Yi and the others can only fight all the way in.

In the passage, Wu Yi encountered a lot of biochemical ghosts, which were guards arranged by the biochemical brood, and the more he went inside, the greater the resistance he received, and the more biochemical ghosts there were. The relatively powerful biochemical ghosts of the Hulk also began to appear.

Wu Yi led the summons all the way forward, with the Ancestral Stone Demon and the Skeleton Warrior at the forefront, and the biochemical ghosts could not break through the defense line formed by them.

When dealing with the Heavenly Spider before, because the opponent's destructive power was really terrifying, I couldn't see the strength of the Ancestral Stone Demon's defense, but now in the face of countless biochemical ghosts, the Ancestral Stone Demon's ability to carry pressure is vividly reflected.

Like the Hulk's fist falling on the stone demon's body, even the earth armor around its body could not break through, the hulk turned on the rampage and slammed into the stone demon's body, but the stone demon did not retreat. Instead, the Hulk was shocked and retreated. A burst of dizziness.

Knocked to the ground by the stone devil condescendingly with a casserole-sized fist, the stone devil smashed the hulk's head with the next few punches, and took out a hulk without much effort.

While the Ancestral Stone Demon was rampage among the zombies, several black shadows suddenly jumped down from a height. None other than a couple of swift hunters. The explosive power of their high-altitude attacks is terrifying. With the potential energy that fell from the sky, he barely broke through the earth armor on the surface of the stone demon's body and grabbed the stone demon's body.

Attacked by several swift hunters at the same time. The stone demon was fine, it took the opportunity to grab a swift hunter and swung his fist, and soon the hapless monster was hammered into a puddle of flesh and lay limply on the ground.

In this short period of time, the wound caught by the swift hunter healed quickly, and the recovery was as fast as ever, as long as the stone devil's feet stepped on the earth, it would be protected by the earth, and the speed of life recovery was really amazing, and the damage caused by the swift hunter was not as fast as the stone demon's recovery.

With the Stone Demon carrying the pressure in front of him, the Skeleton Archer was able to output with peace of mind, and from time to time it fired a shuttle of flaming bullets from its muzzle, it was always lethal when it struck, and a single shot took away several biochemical ghosts, never leaving a wounded.

It fires two types of flame bullets, one is a dark infernal flame bullet with burn damage, and is most effective against the Greedy Ghost, a fire-fearing biochemical ghost, which can light a thick-skinned greedy ghost into a torch with a few bullets.

The other bullet is the effective pale soul armor-piercing bullet, which has the effect of ignoring defense, plus the skeleton shooter's own ignoring defense effect, ordinary biochemical ghosts are simply like running naked in front of it, without any protective effect, and the best effect is to use soul armor-piercing bullets to deal with low-level biochemical ghosts.

Wu Yi has no Demon Slayer Warriors, but he still has a plasma terminator to clean up the large group of zombies, and after the terminator is integrated into the high-energy crystal, the plasma energy has increased again, and the electric energy attached to the bullet is more.

Coupled with the lightning damage attached to Wu Yi's own Thunder Fury, every bullet fired by the Terminator flashed with electric light, and the entire bullet was dyed dark blue, forming a gorgeous blue trajectory when it slashed through the air, and the muzzle of the Terminator was even more dazzling, so that Wu Yi's entire person was shrouded in electric light.

The Terminator is like a mobile turret, and wherever its guns are pointed, it will set off a storm of blood, and no one can stop it.

After Wu Yi and the others advanced a certain distance, they finally encountered the resistance arranged by the biochemical brood, and a large group of sniper ghosts hid in the passage and launched a sniper attack on the enemies who dared to show their faces.

The Ancestral Stone Demon was subjected to a joint sniper attack from them, and the Earth Armor encountered a powerful challenge in an instant, and was shot by a large-caliber bullet that caused a ripple, and then was pierced by two more powerful bullets, and several shallow craters were shot out of its body.

Wu Yi keenly noticed that the figures of the two assassination ghosts disappeared in a flash, it was their snipers who broke through the armor of the earth, which made Wu Yi very vigilant in his heart, Yue'er and Yang Qinghui did not have the defense and health of the stone demons, so it was better for the two of them to be careful.

When it was set on fire by the sniper ghosts, the Ancestral Stone Demon did not retreat but advanced, it took the initiative to activate the armor of the earth, and the yellow armor covered on the surface became thicker, rushing forward, and the sniper ghosts had to shoot again and again, causing the armor of the earth to ripple again and again.

Wu Yi took out the Beidou Demon to kill the sniper ghosts hiding in the shadows one by one, each shot was right in the forehead, and the damage of the Beidou Demon + headshot was enough to kill the fragile sniper ghosts in seconds.

The skeleton shooter also hides in the shadows and shoots the Yin Gun, which is even more indecent than assassinating the ghost.

When the assassination ghost couldn't hold back and blocked the pace of the Ancestral Stone Demon, under Wu Yi's tracking technique, the assassination ghost had nothing to hide.

Wu Yi and the skeleton shooter shot at the same time, and Wu Yi's sniper assassination had thousands of damage. Snipe an assassination ghost, and the skeleton shooter's aiming shot + black gun damage is not low, and the other assassination ghost is severely damaged, and the next shuttle bullet will solve it.

When the Ancestral Stone Demon rushed into the position where the sniper ghost was, its feet slammed down, and the whole earth shook with it, and there was a rumbling sound like an earthquake, and the ground cracked a lot, and the rubble flew around, and after being hit, it would break its head and bleed. There are also invisible shock waves spreading. Deals damage to enemies within a radius of the earth.

The Ancestral Stone Demon used a blow that shook the earth, and the sniper ghosts were all severely damaged, and the ground became rugged again, and the movement speed of the sniper ghosts was greatly reduced. Then the skeleton soldiers who arrived approached closely. There was a one-sided massacre.

Just hit these sniper ghosts hard. More cyborg ghosts rushed up, sending sporadic sniper ghosts fleeing to the rear.

This time, all the people who rushed up were biochemical ghosts above the boss level, Abomination, Metal Assassin, Shadow Baby, and Ghost Ninja.

There are also large groups of steel-toothed jaws and infernal claws. There are also some big guys like the Black Steel Beast and the Red-Eyed Giant, and although the space in this passage is quite spacious, a monster of the Black Steel Beast's size still feels cramped, and there is something that can't be used.

The Ancestral Stone Demon was besieged by many biochemical monsters, and this time it did feel the pressure, like a huge hammer blow launched by the red-eyed giant, because it was a crushing damage, it had a certain restraint effect on the stone demon, and smashed a lot of broken stones on the stone demon's body.

Hellclaw and steel-toothed jaws launched an assault on the formation of skeleton soldiers, and the two were inseparable, and with the help of the wolves, they were able to withstand the onslaught of the biochemical ghosts.

Wu Yi entered the state of the mobile turret with the plasma terminator, and then turned on the plasma laser, which kept spraying lasers from the barrel of the gun, sweeping through a large area of biochemical ghosts.

The skeleton shooter also entered the hell warrior state, and there were two flames attached to the bullet, and the hell flame and the soul fire fused together, producing a magical reaction, and after the bullet hit the enemy, the flames above exploded and swept all the enemies within three yards around, and the skeleton shooter's normal attack directly turned into area damage, which worked very well against the zombie sea.

The flames from the bullet blasted were like tarsal Gus, and it took a long time to extinguish them, and the burn damage alone was too much for the biochemical ghosts to bear, and the abominants were cleaned up in the first place, and the air was filled with the smell of burnt flesh and blood.

Seeing that the red-eyed giant and the black steel beast were besieging the Ancestral Stone Demon, Wu Yi turned on the focused high-energy beam, and six fiery red beams shot out from the barrel of the gun, and shot intensively on a red-eyed giant, reflecting each other, and the high-energy beam produced a large amount of burning damage.

As soon as the red-eyed giant was set on fire by the high-energy beam, its body curled and shrunk at an extremely fast speed, and in the high temperature, the flesh and blood of the red-eyed giant were instantly dissolved, and after two or three seconds, it collapsed to the ground, dead no more.

The Ancestral Stone Demon slammed into the Black Steel Beast with a fierce punch, a layer of red light on its fist flashed away, and the black biochemical armor on the surface of the Black Steel Beast was directly shattered, and the fist fell on the Black Steel Beast's chest, and the Black Steel Beast was beaten so that it vomited blood and retreated, and after stopping, its body was covered with fine wounds, and its expression was a lot more depressed.

Because of the relationship between the blood of the ancestors on the stone demons of the ancestors, the stone demons have an absolute suppression ability to the biochemical ghosts, the more advanced the biochemical ghosts, the more pure and active the ghost virus on the body, and the greater the suppression of the blood of the ancestors.

Under the fist of the Ancestral Stone Demon, the biochemical armor of the Black Steel Beast is useless, and the extra damage attached to the blood of the Ancestor becomes absolute damage when facing the biochemical ghost, and it can also reduce the attributes of the biochemical ghost, which shows the strong restraint of the blood of the ancestor against the biochemical ghost.

Wu Yi rushed to the Ancestor Stone Demon with a swift wind step, and he used a set of swordsmanship in a row to severely damage a black steel beast, and finally blasted it into two with a triple nail fist.

After cooperating with the Ancestral Stone Demon to kill the Black Steel Beast and the Red-Eyed Giant around him, Wu Yi and the Ancestral Stone Demon stepped down with both feet at the same time and launched the Earth Shock Skill, the skills of the two were superimposed, and the Ancestor Stone Demon even swung out his arm and used the landslide skill.

The effect of shaking the earth made the whole earth tremble, and the earth seemed to be in a rage, roaring and shaking, and people stood on it like a roller coaster with the ups and downs of the ground and tossed, like a boat in the angry waves, unable to grasp the balance of the body, and it took great courage to even move it.

Because of Wu Yi's addition, this scene was much more terrifying than when the Ancestor Stone Demon was used alone, and the ground was cracked with countless cracks, some of which were even an arm's width wide, and they would fall into it if they were not careful.

And with the effect of the landslide skill, the cracks in the ground have expanded a few points, and the deep underground of this passage has increased the power of the skill by a few points, and the entire passage shook the sky and the earth cracked, countless gravel fell, and countless gravel flew from the ground, covering a large area in front of the stone demon.

The smallest of them were the size of a fist, and with a terrifying speed, they were rubbed with a bloody wound, and those stones with the size of a human head were even more terrifying, and they had to vomit at least three liters of blood after being hit.

Wu Yi saw an alloy assassin smashed his head by a boulder, and the headless corpse languished to the ground, while the boulder smashed a steel-toothed jaw behind it with undiminished power.

The effect of the landslide and ground crack caused by the landslide and the landslide is indeed terrifying, the two skills cooperate with each other, and even Wu Yi's earth-shaking skill has also been bonus, causing thousands of area damage at once, and there is hardly a intact zombie in the range covered by the skill.

The Skeleton Archer also took the opportunity to shoot several fire grenades, and finally a whirlwind of hellfire blasted out, when the hellfire swept the whole field, the hot heat wave became a terrible killer, several hell claws barely survived the landslide, but in the ensuing fire whirlwind swayed their bodies and were burned into charred corpses.

The living biochemical ghosts are all high-defense and thick health, but they are also covered in gray faces, and the corpses lying on the ground are even more tattered or charred, either succumbing to countless shockwaves and rubble, or they have become a hot corpse under the flames and heat.

Yue'er screamed in pain at the right time, and the terrifying sound waves spread, causing a lot of damage and pain to this group of biochemical ghosts, and clearing some of the hard-hit enemies.

After Wu Yi completed the upgrade task, Yue'er also rose to a higher level and comprehended a super-large damage skill called Ultrasonic Shockwave, but due to the long buffer time, Yue'er would not use it until the critical moment.

The Ancestral Stone Demon suddenly reached out and grabbed a steel-toothed jaw beside it, throwing it up, and after slamming hard at the top of the passage, it fell from above, sending off a shockwave as it hit the ground, damaging a large area of enemies and clearing up a lot of biochemical ghosts.

After the landslide and ground crack + throwing, the remaining biochemical ghosts did not pose much threat to Wu Yi and the others, and under Wu Yi's five-in-a-row nail fist, the last red-eyed giant collapsed to the ground, and the passage to the direction of Shenhua Mansion was no longer obstructed.
