What surprised Ye Feng was not that Zhang Ying smashed a target, but that Zhang Ying became stronger and braver the more he fought, and this kind of fighting stronger and stronger was not an exaggeration, nor was it a psychological effect, but a reality.

After four hours of frantic slaughter, at least more than three hundred first-order zombies were killed, more than two-thirds of which were killed by Zhang Ying, especially until now, Zhang Ying did not reduce the killing speed because of his strength, but became faster and faster.

Killing zombies in a row is like running a marathon, which is abundant at first, but as the running process progresses, the physical exertion becomes more and more serious, and the speed naturally becomes slower and slower.

However, Zhang Ying is the opposite, on the contrary, his speed is getting faster and faster, like a tireless machine, which has adapted to this kind of high-intensity zombie killing.

"The ability to adapt is really full of potential." Looking at Zhang Ying, who was frantically killing zombies like a gopher smashing a gopher beside him, Ye Feng sighed in his heart, even if Ye Feng himself, after four hours of killing, his body would be tired, and it was impossible to be like at the beginning.

The two of them slaughtered all the way in the Ya Academy, and almost all the zombies they encountered were killed.

"That's all for today, let's go back to the lab building first." This kind of high-intensity slaughter lasted until the afternoon, when Ye Feng stopped Zhang Ying in the high-speed killing.

For Ye Feng's order, Zhang Ying naturally obeyed unconditionally, she stopped the mechanical chopping, followed behind Ye Feng, and quickly ran towards the experimental building.

"Let's go take a shower first!" Back in the experimental building, Ye Feng looked at Zhang Ying, whose whole body was already stained with blood, took out a set of clothes from the space ring and handed it to Zhang Ying and said.

At this moment, Zhang Ying was like a demon crawling out of a pool of blood, his body was stained with blood, internal organs, and a brain like tofu dregs, and as long as he stood in one place and did not move, the blood soaked in the black robe would flow down from his clothes and gather under his feet, forming a puddle of blood.

"Hmm." Zhang Ying took the clothes, answered, and walked towards the women's toilet in the corridor on the third floor.

Now the entire Yashi has been cut off from electricity, but the experimental building has a generator and a water tower, so there is no need to worry about water and electricity for a long time.

When Zhang Ying left, Ye Feng took out a pocket from the space ring, opened it and saw that it was full of red crystal nuclei, and with a slight estimate, it reached at least six hundred crystal nuclei, which was considered a bumper harvest.

Seeing so many crystal nuclei, even Ye Feng's heart was pounding, and he couldn't help but show excitement and excitement, and secretly rejoiced in his heart for his choice to invest in Zhang Ying.

In the early stage of the disaster, if you want to obtain so many crystal nuclei at one time, except for the army, few forces can obtain them, and even if the army wants to obtain more than six hundred crystal nuclei at one time, it will need to pay a lot of price.

Don't look at Ye Feng going out in a day, he can get at least dozens of crystal nuclei, or even hundreds, that is because Ye Feng has experienced the end of the world, has twenty years of survival experience, and belongs to the fighter among the old birds.

If you go out to hunt zombies for other evolutionaries, it is already very good to be able to get ten crystals a day, because in the city, hunting and losing guns, the sound of gunfire will attract zombies and fall into the corpse group.

But with cold weapons, the efficiency of killing zombies has become very low, and because you don't understand the habits of zombies, and you don't take advantage of cold weapons and don't use them skillfully, you are even hunted by zombies.

Some human beings are lucky enough to stimulate their potential and become evolutionaries, but they do not have the consciousness of evolutionary beings, and they do not know that they can continue to evolve, let alone that they can be immune to zombie viruses after becoming evolutionaries.

The world before the catastrophe was the worst of times, but also the best of times.

Most of the people in this era live in peacetime, and there is almost no killing in their lives, and even the vast majority of people have never fought a few times in their lives.

The inherent thinking of peacetime makes the vast majority of people, in the face of sudden and drastic changes in the world, often at a loss, and do not know what to do.

Therefore, the evolutionaries in the early stage of the disaster, not to mention actively hunting zombies, often run away when they see zombies, and even some timid evolutionaries, because of fear, are unable to effectively resist in the face of zombies, and are finally bitten to death.

Ye Feng put away the crystal nucleus, came to the men's toilet, picked up the bucket placed next to him, put it under the faucet, and turned on the faucet.

The experimental building, not a lodging, there is no bathroom here, the so-called bath, is to fill a bucket of water, and then rinse the whole body with a bucket, which is equivalent to taking a cold shower, but for the physique of the evolutionary, taking a cold shower will never catch a cold.

After washing the blood, Ye Feng changed into a set of Puma's sportswear, and the shoes were also replaced with brand new Umbro sneakers, the original blood-stained clothes and sneakers were thrown away directly, and now in the end of the world, all kinds of brand stores, take them at will, as long as you have the ability to go in, you can get a new one every day.

Putting on new clothes, Ye Feng came to the test bench, picked up the chocolate placed next to him, tore open the brown bag, and then put it in his mouth to chew to replenish the energy consumed during the day.

Not long after Ye Feng came out of the men's toilet, Zhang Ying also came out, at this moment, Zhang Ying took off the black robe that covered her whole body, put on the sportswear and Converse sports shoes that Ye Feng gave her, and she looked suddenly a little fresh, and her whole body was full of youthful vitality.

Zhang Ying is tall, pure and moving, the age is the flower season, just sixteen years old, a girl of this age is in a period of youth and vitality, youth has no ugly girls, not to mention that Zhang Ying is a beauty.

Looking at Zhang Ying who came to the hall, Ye Feng's eyes were a little frozen, and he looked directly at the other party, his eyes motionless.

Zhang Ying, who came to the hall, found that Ye Feng had been looking at her, and lowered her head a little unconsciously, although she was branded by Ye Feng with a spirit, but this imprint did not affect her IQ, her thoughts were exactly the same as before, but she formed a view that she had to obey Ye Feng in her inherent thinking.

Ye Feng looked at Zhang Ying unabashedly, but Zhang Ying lowered his head, and the atmosphere suddenly became awkward.

After half a ring, Ye Feng came back to his senses and said in a surprised tone: "It's incredible." ”

"What,,, what,,, incredible?" Zhang Ying turned his head to look at himself, but he didn't find anything incredible, and looked up at Ye Feng with a puzzled look on his face.

"You're evolving too fast, don't you feel it?" Ye Feng bypassed the test bench and walked to Zhang Ying's side, his face full of surprise.

When he went out this morning, Zhang Ying's life intensity was only 1.24 times, and now it has reached 1.29 times, a full five percentage point increase.

Hearing this, the puzzle on Zhang Ying's face became even stronger, obviously not understanding what Ye Feng was talking about.
