The next day, early in the morning, Ye Feng still got up very early, and as soon as the sky was bright, he got up.

When he came to the side of the wire bed, Ye Feng found that Zhang Ying quietly had an extra tweed coat on his body, covering his entire body.

Ye Feng took a closer look at Zhang Ying and found that the other party was recovering well, most of the mucus on his skin had disappeared, and the light red pink skin began to grow out of the subcutaneous tissue.

And Zhang Ying's eyesight also slowly recovered, otherwise how could he see Ye Feng's clothes next to him, and then cover himself.

"Did you wake up?" Ye Feng asked.

"Woke up." Zhang Ying nodded, and his words became clearer and clearer, only his voice was very hoarse.

"I'll inject you with the Evolution Fluid now." Ye Feng said as he took out the two evolution liquids extracted yesterday.

Hearing the injection of evolution solution, Zhang Ying obediently stretched out his hand.

Ye Feng took Zhang Ying's palm, looked for a vein, and began to inject.

After injecting two vials of evolution liquid in a row, Ye Feng began to mix milk powder again, and then raised Zhang Ying's head and fed the milk powder to her mouth.

"I'm going out, if your body is back to action, the milk powder is next to you, drink a little if you have nothing to do, this will help your body recover." After feeding the milk powder, Ye Feng instructed.

Although the energy contained in milk powder is far lower than that of the evolution liquid, but the milk powder is easy to get, Ye Feng took a total of more than a dozen cans, and among ordinary foods, the nutritional value of milk powder is very high.

"Okay." Zhang Ying nodded.

When Ye Feng left the hall and disappeared at the corner of the corridor, Zhang Ying said in an inaudible voice, "Be careful." ”

Time was spent in the boring and monotonous hunting, Ye Feng went out every morning, hunted zombies, came back at night, and then extracted the evolution liquid and injected it into Zhang Ying's body to help her recover her body.

====

Five days later, Ye Feng came back from hunting zombies.

"You're back!" Seeing Ye Feng come to the hall on the third floor, Zhang Ying, who was standing next to the test bench, put down the experimental equipment in his hand and looked at Ye Feng.

As early as three days ago, Zhang Ying was able to get out of bed and walk around, and said that he could help, Ye Feng told her the extraction method of the evolution liquid, Zhang Ying, who has the ability to adapt to regeneration, learned and got twice the result with half the effort, and quickly mastered this method, and could already extract the evolution liquid alone.

"Well, how do you dress like this?" The moment he saw Zhang Ying, Ye Feng's face showed a hint of surprise.

At this moment, Zhang Ying was wearing a set of black robes, covering his whole body, and even his entire cheeks were shrouded in black robes, revealing only a pair of cold eyes, which looked full of mystery and weirdness.

"You ,,, you don't like me dressed like this?" Zhang Qian looked at Ye Feng with a hint of panic in her eyes.

"No,,, no, if you like it." Ye Feng hurriedly shook his head, although Zhang Ying was his subordinate, he would not deliberately ask her to dress, after all, after the end of the world, all kinds of clothes were no longer strange.

Ye Feng was just a little surprised, after five days of recovery, although Zhang Ying's body had not fully recovered, his appearance had almost recovered, and he had also grown new skin, and the newly grown skin was fairer and more crystalline, again, he had returned to the demeanor of the former beauty.

However, Zhang Ying, who had restored his former appearance, instead put on a black robe and covered his whole body.

"Captain, you don't have to call me Zhang Ying in the future, just call me Shadow." Zhang Ying saw Ye Feng's casual expression, knowing that the other party didn't dislike her dress, his heart was relieved, and then he said.

"Good!" Ye Feng agreed very simply.

Seeing Ye Feng agreeing so simply, a trace of surprise appeared in Zhang Yingqing's cold eyes, but he quickly recovered, through a few days of contact, Zhang Ying also had some understanding of Ye Feng's style of doing things, Ye Feng's ability to accept new things was far beyond ordinary people, and naturally he was not surprised by Zhang Ying's requirements.

"Here, this is the crystallization of today's hunting zombies." Ye Feng handed out a bag full of crystal nuclei.

Through a day's hunting, Ye Feng only harvested less than seventy crystal nuclei, which was twice as small as at the beginning, it was not that Ye Feng was lazy, but that now the zombies are evolving faster and faster, and the strength of the zombies is getting stronger and stronger.

In the past, Ye Feng alone could single-handedly take on dozens of first-order zombies, but now Ye Feng was a little difficult to face ten zombies at the same time.

This is not the main reason for Ye Feng's reduced hunting efficiency, the main reason is that there are more and more zombies that have evolved to the second order, and even Ye Feng found that one has evolved to the peak of the second order, and it is only one step away from being able to evolve to the third order.

The third-order zombies could already really threaten Ye Feng, which made the shadow in Ye Feng's heart become heavier and heavier, and a sense of crisis quietly surged into his heart.

"Shadow, you come over first, you don't need to extract the evolution liquid for the time being." Waiting for Zhang Ying to take the bag, Ye Feng pointed to the empty space in the hall and motioned for her to come over.

"Yes!" Zhang Ying's words are concise and to the point.

"Try it, here's the weapon I got for you." Ye Feng took out two short-handled axes with strange shapes from the space ring and handed them to Zhang Ying.

These two axes were found by Ye Feng when he was passing by a hardware store, and he also used the tools of the hardware store to process them, so that these two short-handled axes were very strong, and even the axe handles were steel, and they were heavy in their hands, like holding two dumbbells.

Zhang Ying took the two axes, held them very heavily in his hand, and looked at them carefully, the axe handle was about twenty centimeters, and the axe surface was very thick, the width of an adult's palm.

"You find something to try first, get used to the weight of the axe." Seeing Zhang Ying take the axe, Ye Feng pointed to a wooden table next to him and said.

Zhang Ying nodded, walked over silently, came to the wooden table, and slashed with an axe.

"Smack!" There was a crisp sound, sawdust flew, and the tabletop, which was a palm-thick, was directly smashed by the axe.

Seeing Zhang Ying slashing, Ye Feng nodded with satisfaction.

The axe is one of the most effective weapons against low-level zombies, and the effect even exceeds that of a war knife, especially against first-order zombies, it is almost invincible, and it kills in an instant, but Ye Feng is used to using a war knife in the original universe.

Ye Feng was looking for some good quality clothes, crumpling them into a ball, making a round ball the size of a baby's head, and then hanging it on the ceiling of the hall with hemp rope, so that the cloth ball was about one meter and a half from the ground.

After hanging this cloth ball, Ye Feng asked Zhang Ying to come over and chop the cloth ball with an axe, because the cloth ball is suspended and falling, as long as the axe is hit, it will swing immediately, so it is a little difficult to continuously split the cloth ball, and you need to be sensitive to the axe.

This kind of training method is very common in the last days, and human beings have summed up a lot of experience in the battle with zombies, and many axe companies have been quietly born in the human army.

Compared with spears, broadswords, and swords, short-handled axes are convenient, fast, and extremely lethal in hand-to-hand combat between human corpses.

In the battle of human corpses, once the zombies rush through the defense line and fight with the human army hand-to-hand, then the axe company is the vanguard, blocking these zombies who rush into the defense line.
