Walking out of the laboratory, Ye Feng planned to clean up the zombies in Ya Academy first, and then clean up the zombies on the street outside, so that he would clean up all the way, and when Zhang Ying mastered the ability, he would leave Ya City.

First of all, he chose to clean up Ya Academy, and there was another reason, the second-order butcher in the school had been led outside by Ye Feng, and the possibility of encountering second-order zombies again in the school was very low.

Although Zhang Ying's ability is very domineering, her evolution level is too low, and she has never fought with zombies, once she encounters second-order zombies, it is very difficult to fight, it is better to use the first-order zombies in the school to practice, there is an adaptation stage.

"When you're fighting zombies, try not to chop at the opposite side, you need to go around their backs and sides, and you're slashing their axes and blasting their heads." Standing on the campus street, Ye Feng pointed to the several zombies wandering in front of him and said.

"Hmm!" Zhang Ying nodded, clutching the short-handled axe, his eyes fixed on the zombie in front of him.

As early as yesterday, Ye Feng explained to Zhang Ying in detail the habits of zombies, as well as some combat skills.

Under the full strength of the zombie, although the speed can reach 80% of the adult, but it is a straight run, if it is a sharp turn of running, the speed of the zombie is greatly limited.

After humans mutate into zombies, they not only lose their intelligence, but also greatly reduce their neural reactions, so when an adult fights zombies, he suddenly walks around to the zombies and can kill the zombies before they react.

The early human beings did not understand this, as soon as they met the zombies, they were already frightened to lose their basic observation and judgment, and blindly ran away from the zombies in the fastest straight line, and did not know how to make sharp turns, so that the zombies would give full play to their greatest advantages.

"Go ahead, remember, don't be nervous, your abilities are very powerful, not only will you not be infected with the virus, but even if you are bitten by them, you will recover quickly." Ye Feng waved his hand and signaled that Zhang Ying could fight.

Hearing this, Zhang Ying shook the short-handled axe in his hand, and rushed towards the zombies in front of him quickly, covering the black robe all over his body, so that people could not see her expression, and could only see a pair of eyes that were as cold as a cold pool.

As Zhang Ying approached, the three-headed zombies wandering in front of him also found the food that appeared, and immediately turned around, looked at Zhang Ying, who was dressed in a black robe, opened his big mouth full of fangs, and made a low "hiss" sound, rushing towards Zhang Ying.

The distance between the two sides was not far away, and in the case of hedging, it was already close to less than three meters in just a few breaths.

Seeing the zombies close at hand, Zhang Ying's cold eyes did not have the slightest emotional fluctuations, let alone fear, for fear, I am afraid she is already immune, Zhang Ying, who has experienced that kind of torture, has extraordinary endurance.

Just when the zombie who rushed to the front was almost close to Zhang Ying, her body suddenly turned to the side, and the figure appeared ghostly on the right side of the zombie, raised the heavy axe, and slashed at the zombie's head.

"Smack!" A crisp sound of bones shattering sounded, Zhang Ying's axe was very accurately draped on the zombie heavenly spirit cover, and the sharp axe instantly broke through the zombie's solid skull, and the zombie's head was shattered like a watermelon, splashing red and white.

Because the zombie was split off in the process of rushing forward, under the action of inertia, the zombie continued to rush forward for two or three meters before falling to the ground.

After killing the first zombie, the two zombies in the back also rushed over, Zhang Ying held the axe in both hands, and used the method handed over by Ye Feng to be calm, see the opportunity, detour behind the zombie and the side, and shoot in an instant, with a headshot.

"Smack! Syllable! Two crisp bones shattered sounded, and the two zombies were shot in the head in two seconds.

It is not easy for ordinary axes to easily split a person's head, and it is even easy to get stuck in the skull, after all, the skull is the strongest bone in humans.

However, the axe modified by Ye Feng was not originally for ordinary people, but for evolutionary use, and the general axe, even if the axe handle is not wood, will only use a steel pipe, that is, hollow, too heavy, too laborious and flexible, so a short-handled axe often weighs less than 4 kilograms

However, Ye Feng created a short-handled axe, which was fully solid, especially the proportion of the bevel of the axe blade, which was completely consumed according to the experience of the end times, a short-handled axe, weighing a full 13 kilograms, could easily shoot the head with an axe.

"Yes, go ahead." Ye Feng saw that Zhang Ying could easily kill the three-headed zombies, and he was extremely skilled in the use of short-handled axes, and he could easily slash the Heavenly Spirit Gai of the running zombies, and said with a satisfied look on his face.

Zhang Ying heard Ye Feng's words, nodded, and continued to look for zombies, while Ye Feng was just following behind Zhang Ying now, collecting zombie crystal nuclei.

In this way, the two began to sweep the zombies in Ya Academy, and as the two kept fighting, the smell of blood continued to attract the zombies on the campus, and several times, dozens of zombies appeared to besiege the two at the same time.

Once encountering a large number of zombies, Ye Feng will take action, and the two of them join forces to kill zombies very quickly, especially Zhang Ying's short-handled axe, which is almost a zombie nemesis, one axe at a time, clean and neat.

Killing zombies with a short-handled axe, compared to Ye Feng's war knife, saves a lot of effort, and there are a lot of aspects, killing zombies with a war knife, if you want to kill with one blow, you need to attack the relatively fragile neck of the zombie, if you split your head like an axe, I am afraid you need to pay three times the strength of the axe.

When the knife chops the head, the power is scattered, and it is easy to be stuck by the zombie skull, the war knife is a flashy weapon, and the average person uses the war knife to kill the zombie, which is not only inefficient, but very difficult.

Only Ye Feng is like this, after twenty years of killing, he is already very familiar with the war knife, the war knife in his hand, just like his own hands, like cutting there, you can cut there, and more importantly, Ye Feng knows how to use skill, otherwise after cutting off a few zombies in a row, the tiger's mouth will directly crack, and his wrist will be sore, which will seriously affect the next battle.

The two of them fought from the west gate of the school to the east gate, and encountered several zombie groups of more than 100 along the way, but they were all killed by the two of them one by one.

In the process of slaughtering zombies, both of them were injured, Ye Feng was bitten by the zombies and scratched several times, Zhang Ying was not as lucky as Ye Feng, most of the original black robe was torn by the zombies, revealing white skin.

And Zhang Ying was covered in blood all over his body, he was bitten seven or eight times, as for being scratched, he couldn't count it, and along the way, almost all over his body was covered with wounds, and his black robe was completely soaked in blood.

Of course, such a high-intensity battle makes Zhang Ying's fighting skills more and more proficient, and he uses an axe to shoot zombies in the head, and at this moment, Ye Feng, who was standing next to Zhang Ying, saw Zhang Ying kill zombies with an axe, just like smashing a gopher.
