Zombie animals such as zombie elephants, zombie rhinos, zombie hippos, and zombie animals with strong defense are difficult to cause substantial damage to them even if other psychics take action.

This is the case with Xu Youcai's flying knife. Unless he changes his weapons, controls hundreds of firearms at the same time, and shoots at the same target, his flying knife with these characteristics can only barely break through the flesh and stab it one or two centimeters deep.

However, after these zombie animals mutated, they were at least three meters tall and at least five or six meters long. Such a small wound was irrelevant to them.

Other fire, water, soil, etc. are almost the same, and they cannot cause any actual damage to these zombies.

However, this seemingly hard and invincible defense is fragile and vulnerable in front of Iyalan's space cutting ability.

Iyalan was just a crack of space the size of a palm-sized space, which could easily cut the head of a zombie rhino out of it, making it die so hard that it could not die again.

It can be said that with Yiyalan's actions, all of these extremely threatening zombie animals on the entire southern city wall were killed in just a few minutes.

Although Yiyalan didn't take many shots, her role was even greater than Xu Youcai.

This is the irreplaceable role of a top-notch man in a war.

Perhaps they cannot withstand the tide of corpses, but with their strong combat power, they can solve some problems that the army cannot handle.

And it is obvious that Yiyalan is such a powerful man.

Moreover, the four base teams are located in the center of the defense line. With their cooperation with each other, they suppress the attack of the corpse tide, which will naturally cause some chain reactions.

In addition, with the existence of two superpowers, Xu Youcai and Yiyalan, especially Yiyalan, who took action to solve the top zombies one by one, the pressure on the entire defense line was slightly reduced.

Although it's just a few, it's extremely amazing to do this in this eight-kilometer-long defense line.

Even this alarmed. The senior coalition leader who was commanding on the south wall, the major general sent by Beijing, came directly to Xu Youcai and others, and personally praised and encouraged.

Such behavior certainly made Xu Youcai's vanity soar, and even killed zombies more efficiently.

However, after killing for half an hour, Xu Youcai was a little tired of this behavior. After all, it was always killing, killing, and killing again.

So while Xu Youcai was killing, he gradually shifted some attention to other aspects.

For example, the merit points he has accumulated.

The battle has been going on, so the merit points in each base are increasing continuously. The senior coalition leaders will announce the number of merit points every half an hour.

Although doing this will cause some trouble for the senior coalition leaders, it also has its benefits, because this long-term high-intensity battle can easily make people numb. It is okay for a short time, but if it is long, some mistakes may occur.

Using meritorious points to constantly stimulate the nerves of these soldiers is undoubtedly a good choice and can be regarded as a way to inspire morale.

Xu Youcai has the privilege and asks every five minutes how much his merits have increased.

A superpower like Xu Youcai and his contribution is still so great. Of course, it is impossible for the messengers from the senior coalition forces to say something because of this small request.

In the next battle, Xu Youcai basically knew how many merit points he had obtained every five minutes, and he was thinking about what to buy with these merit points.

This kind of thing can be considered a fun thing for a wealth fan like Xu Youcai.

Of course, in addition to the merit points, Xu Youcai also observed that there was an interesting setting in this city wall.

This setting was discovered suddenly after he killed for a while.

Because they keep killing zombies, under normal circumstances, these zombie corpses will soon accumulate and pile up higher and higher.

Therefore, in general, after killing zombies for a period of time, you need to set fire to burn the corpses to clean up all of them.

But here, Xu Youcai found that the zombie corpses under the city wall seemed not to increase, but instead decreased after a period of time.

This immediately attracted his attention. With careful observation, Xu Youcai quickly discovered the secret.

It turns out that all this was because of a clever setting below the city wall. When the city wall was built, it was not completely blocked, but left a "door" with a width and height of about two meters.

This "door" is usually blocked with rocks and cannot be seen at all. Only when the zombies attack for a period of time and the corpses accumulate on the city wall will the door be opened from inside.

Since the door has been completely blocked by zombies, even if it is opened, there is no need to worry that zombies will rush in.

In this case, the body outside can be safely pulled in, then quickly dissected and removed the evolutionary flesh inside.

As for how to deal with these zombies and animals, Xu Youcai only learned after asking the messengers beside him that they would transport the corpses to the north wall by truck, pour tinker oil on them and then destroy them there.

This can be said to be a killing of multiple goals in one go. The first point is to solve the problem of corpses so that the corpses of these zombies will not be accumulated and stacked up continuously, so that these zombies can easily climb up. This is the most fundamental thing.

As for the second point, of course, it is to obtain evolutionary meat. If it is directly burned with fire, all the evolutionary meat inside will be burned, causing great waste.

The third point is that we can use this continuous zombie corpse to form a fire wall on the north city wall to block the zombies attacks there, thereby saving more troops to defend the other three city walls.

It can be said that such a method is definitely a killing of multiple goals.

"I'm really right here to come to the coalition forces this time. Take this method back to the base for promotion. In the future, it's like giving away money when facing these corpse tides!" Xu Youcai said excitedly.

The messenger who was specifically responsible for recording Xu Youcai looked a little weird. He was also very excited when he saw someone mentioning such a corpse tide.
