Above 64 floors underground, and below 65 floors underground, it is completely the same as two worlds. Pen ~ fun ~ pavilion www.biquge.info

Here, Du Tiange could hear the low roar in the dark, but he couldn't see even a single zombie, whether it was in a semi-dormant state or an active state, as if there had never been a zombie here at all.

In the low roar one after another, Du Tiange was like an invisible ghost, all the way deeper, and soon found that the low roar in the darkness came from a kind of terrifying-looking mutated zombie, with limbs on all fours, thick, muscles and blood vessels like a random mix, five sharp claws, no head, no eyes, on both sides of the blood basin mouth, sharp bone spurs that opened like thorns.

Du Tiange carefully observed this mutant monster, and he couldn't see the characteristics of many people at all.

The number of this kind of mutant monster is not much, they are all alone, and it seems that they have their own inherent territory, when Du Tiange opened the door and made a sound, the mutant monster roared and ran, searching around in vain, just unaware of Du Tiange, who was close at hand.

There are laboratories along the way, the facilities seem to be quite advanced, Du Tiange estimates that it should be at the level between the main world and the world of revenge, no paper documents have been found, Du Tiange's understanding of this place is still only a little bit.

After searching an entire floor, Du Tiange didn't rush any further, and after attracting a mutated monster with a loud sound, he stepped on it and stomped on its back fiercely.

Roar~

The mutant monster was suddenly attacked, its thick limbs tightly against the ground, its bloody mouth opened, and its roar was like thunder, but in an instant, the solid floor cracked, and it couldn't withstand the power of the steel armor.

The physical strength of the mutant monster is roughly around 3, Du Tiange retracted his right foot, and was about to retreat, turning sharply to the side, a gust of wind swept by him, and the mutant monster flew by. Then, when the mutant monster turned and pounced, he reached out and grabbed the bone spur next to the mutant monster's big mouth, causing it to stop from sprinting with all its might.

The moment the mutant monster opened its mouth, Du Tiange dodged to avoid it, and a thunderous roar sounded, and the saliva that spewed out was shot out like a sharp arrow.

Strength, agility, and reaction are also around 3, which means that the strength of this mutant monster is also at this level.

Du Tiange's palm opened, and a white beam of light shot out, blasting a big hole in the mutant monster's body, piercing it, and the mutant monster roared again, with incomparable pain and anger, it didn't seem to be affected, and it pounced on Du Tiange again.

"Ha, it's tough!" Du Tiange didn't waste his precious energy again and used the palm cannon.

When Iron Man Tony designed the steel armor, the palm cannon was not small, and the lethality of high-tech weapons such as missiles and fighters was amazing, and it could explode with one shot. But for this mutant monster, the effective lethality is reduced, and the piercing wound looks terrible, but it is not fatal, and it does not affect its action.

The next moment, in Du Tiange's hand, holding the sharp-toothed scimitar, one knife after another, in the constant roar of the mutant monster, he finally found the fatal place of the mutant monster, located in the chest and abdomen under the mouth of the blood basin.

The subsequent dissection was very bloody and disgusting, but Du Tiange had to do it, and it also confirmed the previous temptation, the chest and abdomen of the bloody mouth were exactly where the disappeared head was, and only the remnants of the skull's facial features could be seen, becoming the central nervous core of the mutant monster, and the thick nerves, like branches, extended from here.

Although the fighting process was deliberately prolonged by Du Tiange, the roar of the mutant monsters continued, and the other mutated monsters on the same floor did not react at all, judging from this, the mutant monsters have completely lost the most important feature of intelligent life, that is, wisdom, which is far from animals such as cats and dogs.

"This is a complete desecration of life!" Du Tiange came up with this idea.

It didn't take much time for Du Tiange to clean up the more than a dozen mutant monsters on the 65th floor underground, that is, one kick and one knife, it was basically a one-sided killing.

Descending to the 66th floor underground, the deathly silence, without a trace of blood, the ground and walls were very abnormally clean, but it made Du Tiange on guard, and an intuition of danger that had been lost for a long time also reappeared in the depths of Du Tiange's heart.

Here, it seems to be the core of this huge underground building, a huge space, divided into four areas, in the middle is a cross passage, where Du Tiange stepped on, it was in the middle of the cross.

The passage seemed to lead to the boundless dark abyss, with his eyesight, and the infrared imaging of the steel battle armor, there was no end in sight, just when Du Tiange was standing in place, looking around, the alarm of the steel battle armor suddenly sounded, and the scan of the view showed that there were active creatures approaching behind him.

The speed can only be described as very slow, Du Tiange turned around and walked forward for a hundred meters, only to finally see the attacking monster in the dark passage, and was shocked on the spot.

The appearance of this mutant monster is difficult to describe in words, and the first time I saw it, the word that came to Du Tiange's mind was "chaos"! Then, it's disgusting!

The blood basin mouth is still there, more like a red **, sharp bone spurs, turning into soft tentacles, attached to the blood basin mouth around, a bit like the stamens of chrysanthemums, it is difficult to say whether there are limbs or not, and there is no obvious torso, it is completely like a large lump of meat kneaded together, and the limbs and torso of zombies and mutant monsters are randomly planted on it, and even the upper body of zombies is still alive.

Du Tiange was sad for a while, tears were about to fall, and he couldn't figure out what it was, what kind of crazy person could desecrate his good life to such an extent.

In the face of this disgusting flesh monster, Du Tiange was a little difficult, with his slow speed like a worm, he was no threat to him, but if he wanted to destroy it, he didn't have the right weapon at hand.

In the super storage space, Du Tiange finally found a 105mm bazooka, chose a high-explosive rocket, retreated a few dozen meters, no need to aim, fired directly, the high-explosive rocket roared out, hit directly, about a quarter of it drilled into the body of the fleshy monster, and exploded.

To Du Tiange's surprise, although there was a fire, there was no scene of broken meat splashing and disintegrating, the meat monster was huge, soft, but extremely tough, and there was a big hole in the explosion, but this injury was nothing to the huge meat monster.

What's even more terrifying is that the flesh and blood around the big hole are tumbling and wriggling, and it almost takes less than 1 second to stop the bleeding, and then it begins to heal at a speed visible to the naked eye.

Du Tiange gasped, just one try, the physical strength of the flesh monster is at least above 7, that is to say, he is wearing steel armor, holding a sharp-toothed scimitar, and with all his strength, he can break open a wound, but that's all.

After thinking about it carefully, Du Tiange reluctantly put away the bazooka, turned around and left, concentrating on searching for what he was looking for. Since this fleshy monster is difficult to destroy and an unspeakable threat to him, it is better to just let it crawl slowly behind him.

The four areas are all biochemical laboratories, but they have different functions, Du Tiange took out the determination to dig three feet into the ground, searched carefully over and over again, and finally found a living room in the innermost part of one of the laboratories, violently broke the safe, and found a stack of 5 notebooks.

The notebook was organized according to time, and Du Tiange did not look through them one by one, but quickly scanned them, threw them into the storage space, and handed them over to the miniature quantum computer of the steel armor to sort them out.

The entire underground building, up to 66 floors, has a thin glass display in every laboratory and room, apparently controlled by a main computer system.

Du Tiange returned to the 65th floor underground, and sure enough, he found the main control room where the main computer system was located, and with a little effort, he turned on the backup power supply.

The lights in the main control room turned on, and on the main console, the display screen that occupied an entire wall lit up, showing that the system was restarting, just when Du Tiange breathed a sigh of relief, suddenly the female voice of the system sounded: "Warning!" Invade! Warn! Invade! The self-destruct system starts and the countdown starts ......"
