In the hall, Zhang Ying used an axe to chop the constantly shaking cloth ball, because the cloth ball swings irregularly, it is very difficult to use the heavy axe to slash, which requires the precise control of the power of the axe bearer, as well as the prediction of the shaking of the cloth ball.

This kind of axe designed by Ye Feng, as long as it hits the zombie, almost one axe, and the curvature of Ye Feng's grinding on the axe surface can make the axe not be caught by the cracked skull after the zombie's head is chopped, and it is convenient to retract the axe.

This curvature, which is also the crystallization of human ingenuity, has been summed up in countless battles, just as mathematicians discovered the golden section point.

To deal with zombies, the best is an awl, because the awl can easily break the zombie's head, and there is no need to worry about getting stuck, and more importantly, with less force, you can crush the zombie's head, which is the awl axe invented by later generations.

However, with the power of Zhang Ying's first-order evolutionary, even without an awl axe, he can easily split the zombie's head, and the axe is not only very lethal to zombies, but also for humans, unlike the awl axe, which is specially designed for headshot zombies.

"Yes, adaptation to regeneration is overbearing." Looking at Zhang Ying, who was constantly chopping the cloth ball, Ye Feng showed a hint of surprise in his heart.

In less than three hours, Zhang Ying split five cloth balls, and the number of slashes reached thousands of times, without any physical exhaustion, not only that, Zhang Ying's hit rate is getting higher and higher, from the beginning of the slash ten times, only one or two slashes, to now, ten times can be split more than eight times.

This kind of hit rate is already very high, even those axe soldiers who have been on the battlefield for a long time in later generations are only that.

This is the horror of adaptability, as long as you want to adapt, you can adapt quickly, others need months, or even years of training to reach the level, Zhang Ying only needs a few hours.

"Shadow, go rest when you're tired!" Ye Feng looked at Zhang Ying, who had been wet with sweat in his black robe, and a trace of admiration rose in his heart, you must know that this girl was only sixteen years old, and a week ago, she was just a student.

"Good!" Zhang Ying panted and coped, but he didn't have the slightest intention of resting.

Seeing Zhang Ying who was so desperate, Ye Feng looked at the two evolution liquids that had just been extracted in his hands, silently took out one and put it on the table and said, "Shadow, when you rest, remember to inject this evolution liquid." ”

Hearing this, Zhang Ying's action of chopping the axe stagnated slightly, and there was a trace of emotion in her eyes, after a few days of recuperation, her body had healed, and she could recover her body without the need for evolution fluid to replenish her energy.

Ye Feng ignored Zhang Ying's surprise, according to the original plan, these two evolution fluids were injected into himself to enhance his evolutionary level, like seeing Zhang Ying who was training so seriously, he still decided to give her one.

Ye Feng was not moved by Zhang Ying's diligence, but considered that after Zhang Ying's overtraining, his physical strength could not recover well, which would affect tomorrow's hunting, after all, Zhang Ying would go hunting zombies with Ye Feng tomorrow.

Of course, Zhang Ying naturally couldn't know Ye Feng's thoughts, and subconsciously thought that Ye Feng cared about her.

For Ye Feng, a person who has experienced the last twenty years, he is used to seeing life and death, joys and sorrows, his heart has long been numb, and he thinks about problems from an absolutely rational point of view, and when he looks at problems, he will hardly mix personal emotions.

Back in the temporary bedroom, Ye Feng injected the evolution liquid into his body, and then slowly closed his eyes.

In the past week, Ye Feng has hunted a lot of zombies, and he has extracted a total of more than a dozen evolution liquids, but all of them have been injected into Zhang Ying, this is the first time he has injected evolution liquid since he became an evolutionary.

Due to the lack of the assistance of the evolution liquid, Ye Feng's evolution is very slow, and according to the commonly used life intensity in later generations, Ye Feng is now only 1.86 times the life intensity of ordinary people.

Of course, this life intensity does not simply refer to a certain aspect such as strength or speed, but is a comprehensive evaluation of all qualities.

For example, an evolutionary with 1.23 times the health intensity of an ordinary person may surpass an evolutionary with 1.55 times the health intensity in strength, or even an evolutionary with 1.50 times the health intensity may be inferior to an ordinary person in strength.

However, being inferior in strength does not mean that it is inferior in other aspects, evolutionaries with high health intensity will always far surpass those evolutionaries with low health intensity in some aspects.

Therefore, life strength is a comprehensive manifestation of the body, including not only all aspects of the body, but even mental power.

For first-order evolutionists, the life intensity is often between 1 and 3 times that of ordinary people, and now Ye Feng is just in the middle stage of the first order, and he can reach the middle stage from the original early stage, which is relatively fast.

However, that is for ordinary people, for Ye Feng, an old bird who has experienced the end of the world for twenty years, this speed is obviously turtle speed, if it is not for the recovery of Zhang Ying, which consumes a lot of evolution liquid, Ye Feng's current life strength is at least 3 times that of ordinary people, that is, the peak of one star.

The next day, early in the morning.

Ye Feng, as usual, got up very early, and as soon as he came to the hall, he saw Zhang Ying, who was dressed in a black robe, playing with the two short-handled axes in his hand.

"You didn't sleep yesterday?" Ye Feng glanced at the hall and found that there were a pair of debris all around, the ten cloth balls made with clothes last night were gone, and they were obviously all consumed by Zhang Ying to practice chopping.

"Hmm!" Zhang Ying nodded.

"Let's go!" Ye Feng didn't say anything, waved his hand, and walked downstairs.

Not sleeping all night is nothing to an evolutionary, especially for Zhang Ying, who has a domineering ability.

Ye Feng walked past Zhang Ying, his expression suddenly moved, he turned his head to look at Zhang Ying, a hint of surprise appeared on his face, and he secretly said in his heart: "How can you evolve so fast." ”

Just now, Ye Feng was more than the sensing distance away from Zhang Ying, and now when he got close to Zhang Ying, he could clearly feel the life intensity of the other party, and at this moment, Zhang Ying's stiff strength reached 1.24 times that of ordinary people.

Last night, when Ye Feng trained Zhang Ying, the opponent's life strength was only 1.16 times, and in just one night, it was too terrifying to increase so quickly.

You must know that Ye Feng now has 1.86 times his life strength, and a large part of the reason is that when he awakened to become an Ability, his life strength had already reached 1.6 times, and his starting point was much higher than that of ordinary people.

Human beings because of physical and genetic problems, after becoming an evolutionary, the starting point is high and low, for example, Zhang Ying belongs to which type of person is lower, and Ye Feng belongs to which category of the upper middle, of course, there are some lucky people who are unlucky, just become an evolutionary, and the life intensity reaches more than 2 times that of the terrifying.

After Ye Feng became an evolutionary, because he had rich experience, although he did not have the assistance of evolution liquid, his strength was far beyond that of ordinary people, and after fighting every day and repeatedly stimulating the evolution of his body, after almost a week, it was only equivalent to Zhang Ying's overnight improvement in evolution.

"Captain, what's wrong?" Zhang Ying saw Ye Feng stop and look at her, looking at Ye Feng with puzzled eyes.

The title of captain was asked by Ye Feng to be called by Zhang Ying, and now the two of them are in a group, which is also equivalent to a team.

"It's okay, let's go!" Ye Feng came back to his senses and strode towards the entrance of the building.

Zhang Ying watched Ye Feng walk over, and hurriedly followed behind, walking outside together.
