"Brother Xu, are you awake?" Yao Yuanyuan's tear-stained face was full of smiles.

Zhang Xu sat up slowly, was picked up by Yao Yuanyuan, who was waiting anxiously, smelling the fresh fragrance, Zhang Xu also smiled, this girl is getting bolder and bolder, I still remember when I was at the gas station for more than a month and a half, I still blushed when I spoke.

"Hiss~my chest~" It may be that Yao Yuanyuan hugged it too tightly and pressed it to the wound.

"Ah, Brother Xu, I'm sorry......" Yao Yuanyuan said apologetically.

"It's okay, by the way, is Liu Yuan okay?" Zhang Xu thought about Liu Yuan's injury.

"He was cured, and the red tentacles absorbed the zombie again, and finally entered your body, Brother Xu." Yao Yuanyuan had also seen Zhang Xu's blood, and then took out a green crystal in his hand, which was left in the skull of the iron-armed zombie, Zhang Xu looked at it, it was the crystal of hope!

"This is taken out by the tentacle, it doesn't seem to be able to absorb it, but it must be useful to you, Brother Xu." After taking the Crystal of Hope, Zhang Xu explained to Yao Yuanyuan the purpose of the Crystal of Hope, he only knew that high-level mutant creatures only had it, and he had privately killed some low-level mutant creatures to feed the hairballs, but there was no one in his brain, Yao Yuanyuan covered his small mouth and closed his mouth in amazement.

"Yuanyuan, you go and call Luo Guanghan." Zhang Xu held the Crystal of Hope, he had no intention of absorbing it himself, he wanted to absorb it for Luo Guanghan and become an evolutionary.

"Well, okay Brother Xu." Yao Yuanyuan's eyes flashed slightly and nodded.

After seeing Yao Yuanyuan leave, Zhang Xu clicked on the quantum instrument on his waist.

"According to the test, the unlock level of the owner's gene is 8.83Lv."

I didn't expect that after absorbing the blood of the iron-armed zombie and his experience after each battle, the increase level was only about 0.5, but Zhang Xu didn't know that the combat experience would only decrease as he improved, and the increased gene unlocking level would gradually decrease.

"Brother Xu, I'm here." At this time, Luo Guanghan had a smile on his face, and he was happy that Zhang Xu woke up.

……

"This is the Crystal of Hope, last time I gave Wu Fanyang a try, but I didn't expect the injury to not only get better, but also become an evolutionary, this time I want to experiment and give it to you directly, do you dare?" Zhang Xu raised his eyebrows, he was not sure himself, he only knew that he had upgraded after swallowing the mutated and reckless Hope Crystal, and he didn't know what would happen to ordinary people.

This time Zhang Xu is to experiment with Luo Guanghan, and Wu Fanyang may have been helped by his own blood last time, in fact, the energy of the Crystal of Hope is not violent, but very gentle, if the success team has more protection, if it fails, Zhang Xu, who may have just woken up, will have to solve Luo Guanghan painfully.

"We soldiers are never afraid of death, I'm willing to give it a try!" Luo Guanghan grinned and smiled.

Picked up the green crystal in Zhang Xu's palm, like a jelly bean, swallowed it gratefully, without a trace of hesitation, and then the hard crystal turned into a liquid, and the sweet taste swept the taste buds, Luo Guanghan swallowed the sweetness, and in an instant, moisturizing the meridians of the whole body, Luo Guanghan felt a sense of comfort and hummed.

And Zhang Xu also observed and recorded Luo Guanghan's every move, and it seemed that there was no need to worry about any harm, this expression was exactly the same as swallowing the Crystal of Hope at that time.

Then Luo Guanghan blushed, like a fever, his lips trembled slightly under his hot cheeks, and the chilling cold feeling made Luo Guanghan's whole body wet with cold sweat, everyone has to go through a metamorphosis to evolve, although it is very similar to the zombie infection, but it is very different, this time Zhang Xu used a quantum instrument to scan to show that the blood in his body is still and relaxed, but the blood is like boiling when infected, and the two are distinct.

One is a devilish punishment, directly burning the infected person with hot blood, and the other gently absorbs the energy in the crystal, although it feels a burning sensation.

In just a moment, this burning sensation almost disappeared, and then Luo Guanghan opened his eyes and felt the change in himself, and then a trace of joy hung on the corner of his mouth.

Excitedly grabbed Zhang Xu and said, "Brother Xu, I'm an evolutionary." ”

"What are your abilities?" After just evolving, no one knew what their skills were, but Zhang Xu secretly scanned Luo Guanghan.

"The target gene unlocked the level of 2.57Lv, and the system scan showed that its lower leg bones, thigh bones were enhanced, and the lung structure was changed, which can increase lung capacity, which is 4 times that of ordinary people."

The level is not as high as Wu Fan Yang, of course, this is also because the energy contained in the Hope Crystal is limited, and it is not as high as the level of the original mutant female eagle.

After examination, it was found that Luo Guanghan's leg bones were different from ordinary people, and his lung capacity had more than doubled, and this series of changes may have increased his running speed.

"Brother Luo, you can run and try." Since Zhang Xu said so, then Luo Guanghan will definitely give it a try.

As soon as he entered the running state, the quantum instrument recorded the changes in Luo Guanghan's body, and in an instant, a gust of wind swept by, and Luo Guanghan was like an arrow on a string, which ejected straight out, and then turned around again, and Luo Guanghan ran back.

Although Zhang Xu's killing state can be seen clearly, but he is not smacked, this is only level 2, and the speed is almost catching up with Zhang Xu of level 5, and the measured speed is 43.2 meters per second, and it is really an evolutionary who specializes in speed type, Zhang Xu is now at the end of level 8, The test is 112.9 meters per second, if the python changes speed, it will be faster, 230 meters per second, directly double the speed, you must know that the slowest rate of fire of ordinary pistols is more than 400 meters per second, Zhang Xu's ordinary speed has reached one-fourth of it, of course, Zhang Xu must not have run for a long time, there is no Luo Guanghan's special lung structure, I believe that Luo Guanghan will be faster to Zhang Xu's extent.

I remember the knowledge of junior high school, the speed of sound in the air is about 15 meters per second under the condition of 1 standard atmosphere and 340 degrees, and it is no longer a dream for human beings to surpass the speed of sound with their bodies.

The 100-meter sprint champion before the end of the world is within 100 meters in 10 seconds, although he is still trying to compress time, but human beings are only worth 10 meters per second, Zhang Xu watched TV before, thinking that people can take 10 meters away in one step, naively taking a step in a second, and now he has found out that he can actually do a lot of things in a second, and now if Zhang Xu estimates to go around a 200-meter track, others still think that Zhang Xu did not run.

"Brother Xu, I found that I am so fast, and I can react to anything." Luo Guanghan in front of him said without beating or panting, and a few small beads of sweat flowed from his forehead, sure enough, the speed evolutionary can continue to run without getting tired, and his eyesight is the same as Zhang Xu's blood, which has the effect of slowing down the picture.

"Then I'm going to show off, hehe." Luo Guanghan was trying to show off his might to the others and give them a chance to surprise.

"Go, go, by the way, we'll leave for the train station in the afternoon." Zhang Xu waved his hand and said.
