Zhang Xu's killing state was lifted, and Zhang Xu, who originally came over, did not show up for the first time, but observed Yu Hongda and Wu Fanyang, until he saw Yu Hongda and Yao Yuanyuan, Zhang Xu couldn't help it.

Yu Hongda died like this, and Wu Fanyang was just knocked unconscious and tied up by Zhang Xu on the 3rd floor.

Untying Yao Yuanyuan's rope, she woke up slowly, the first thing she saw was Zhang Xu, and she immediately threw herself into Zhang Xu's arms, and sobbed softly, the whole thing was full of tears, Zhang Xu just stroked her back, and finally gave her a handkerchief and let her cry as much as she wanted.

Speechless all night......

In the middle of the night, Zhang Xu felt so hot, this violent heat made him subconsciously crawl out of bed to outside, now in the spring of March, the climate outside is still biting cold.

And Zhang Xu was shirtless, lying on the container of the truck, he breathed heavily, and every puff of white mist floated out, but the cold night could not play a role, and the blazing feeling seemed to linger behind him.

No matter how cold it was outside, he still felt like he was jumping into a pit of fire, the heat fading with time.

Slowly, Zhang Xu became groggy, and the cool comfort made him no longer uncomfortable, and finally fell asleep peacefully.

……

"Hmm~" Zhang Xu felt that his waist was very painful, just like moving bricks on the construction site for several days and nights, and when he stood up, his waist still made a clicking sound.

Looking around, Zhang Xu scratched his head, why am I asleep outside?

He moved his joints and twisted his waist, his bones crackling like fried beans.

"Huh?" Zhang Xu touched his chin, it wasn't his own blood, he brought himself out at night, right?

So he summoned his own blood He, and the blood He came out as quickly as a child, Zhang Xu knew that the blood He had a certain amount of wisdom, Zhang Xu tried to communicate with it, but it didn't seem to understand Zhang Xu's words, so he had no choice but to check what was wrong with his body.

Zhang Xu just felt a little uncomfortable in his spine, there should be a problem here, he scanned it with a quantum instrument, he didn't know if he didn't scan, and Zhang Xu couldn't sit still when he scanned it......

"Oops, I'll go! When will you give me a whole tail? According to the X-ray of the quantum instrument, Zhang Xu's spine is wider than the original, the upper half of the spine is hollow, and the other part is the structure of the tail.

As soon as he thought and moved, Zhang Xu felt a pain under his spine, the bone tail broke through the skin, and the pain quickly passed, only to see that the tail behind him was about 1 meter long, and there were closely arranged bones on it, which were staggered, like a poisonous snake swaying behind Zhang Xu's back.

Zhang Xu feels that if Xuehe is a close relative, then this tail is like an arm, which can be curled at will, and the end of the tail is the most powerful, it is like the tail needle of a scorpion, there is an extremely long poisonous needle, and there are bones similar to bone knives above and below the poisonous needle.

Zhang Xu understood that this requires the vacuum in the upper half of Zhang Xu's spine to store offensive fluid, and now there is some unknown fluid in the spine, Zhang Xu tried to use it!

You can spray with the needle at the end of the thought, only to see Zhang Xu's tail emitting a white liquid, which looks unremarkable, and then hits the container under his feet, but he didn't expect the container to hiss, high-intensity corrosiveness, even the iron box can be quickly corroded, no less than concentrated sulfuric acid, and there is no too pungent smell when I smell it.

"This poison is so powerful...... Thinking of this, Zhang Xu felt that the most poisonous should be the zombie virus, and the poison that evolved into the powerful was also evolved by this zombie virus!

Zhang Xu can't help but feel his insignificance now, how did this virus come about, can humans research such a powerful virus?

Zhang Xu saw that the venom of the spine was made very quickly, and this venom did not necessarily have to be splashed and used, but could also be used for poisoning, because it was colorless and odorless......

In addition to the poison needle and the upper and lower bone blades, Zhang Xu slid his tail lightly, and a long opening was left on the container, Zhang Xu nodded with satisfaction.

In the future, with this bone tail combat ability, Zhang Xu's combat ability will be greatly improved, Zhang Xu found that even if his arm is controlled, he can also use the blood and bone tail to attack, which greatly increases his survivability, each blood-colored tentacle is as flexible as his own hands, even if he is asleep, he can also protect himself, Zhang Xu found that as long as it is the bone tail's attack range, the bone tail seems to be as perceptible as an eye.

Zhang Xu had thought before that it would be nice if he could fly, so why were he afraid of those zombies?

Zhang Xu tried to use Xuehe to imitate 4 pairs of wings, but Xuehe did not meet the requirements, and Xuehe was most deformed, straightened, stretched or curled, or liquefied or materialized.

The highest difficulty is to attach it to Zhang Xu and become a set of blood-colored clothes, Zhang Xu used to want to imitate the chameleon's tongue to make his tentacles barb, but the tentacles can't do it at all, Zhang Xu is already very satisfied and can't ask for too much......

"Yao Yuanyuan should be awake, it's time to go back......"

After checking the gene unlock level, Zhang Xu entered 6.22Lv from level 5, even though the battle increased the evolution speed, but the longer it went to the back, because from level 10 to level 1, the difference is several times or even dozens or hundreds of times the energy!

……

Now the plan to take the ring road seems to have failed, and now there are two ways, the first is to find a way to repair the bridge, but the difficulty coefficient is very large, Zhang Xu has no tools and no technology, so he can only detour.

Of course, there is another way to jump and take the central area to reach the train station, which is the fastest and most dangerous!

Since Yao Yuanyuan and Wu Fanyang both knew that they were evolutionaries and did not feel out of place, they used their abilities to open up a way!

"Eat more, and you may not have time to cook when you turn back......," Zhang Xu, who looked down at the map, said and sandwiched another piece of meat for Yao Yuanyuan.

Yao Yuanyuan is also used to Zhang Xu like this, and the blush on his face is not as big as before, but it is still cute, like a tempting apple.

"Goo~" Wu Fanyang was tied in a corner by Zhang Xu's backhand, watching Zhang Xu and Yao Yuanyuan eat, Wu Fanyang swallowed his saliva, looked at the meat slices that Zhang Xu sandwiched, and it seemed that saliva was flowing out......

Zhang Xu didn't care about him and pretended not to hear it, but after his evolution, his hearing was extremely powerful, and he had already heard it, but he just didn't move and ignored Wu Fanyang.

Now Zhang Xu has planned a route, starting from here, turning into a hotel, from the back street of the hotel, into the Luohe Park in the center of the city, passing through a small supermarket, you can sweep it, and enter the TV station in the rear after walking the path of a community, and finally enter the villa area near the train station.

If there are no accidents on the way, these accidents are zombies, survivors, and obstacles in the road, if it goes well, it can be reached in a day, but it will definitely be much slower than beforehand.

"Okay, let's eat enough, Yao Yuanyuan." Packed up the equipment, gave Yao Yuanyuan everything to the hidden knife, and gave her the golden dragon armor, since she knew that it was an evolutionary, then she would use the bone sword, or the bone sword would be sharp.

"Well, eat, eat." Yao Yuanyuan still spoke like this, shy......

"As for you." At this time, Zhang Xu wiped the oil stains on the corner of his mouth, faced Wu Fanyang, and pursed his lips, thinking that in addition to talking a lot of cruel words, this person didn't want to hurt Yao Yuanyuan like Yu Hongda yesterday, otherwise he would have died a long time ago, touched his chin, and then it depends on Wu Fanyang's attitude towards him.
