Zombie animals like zombie elephants, zombie rhinoceros, zombie hippos, etc., have strong defense, even if other abilities make a move, it is difficult to cause substantial damage to them.

Like Xu Youcai's flying knife, unless he changes his weapon, controls hundreds of guns at the same time, and shoots at the same target, his flying knife with these characteristics can only break through the flesh at most and stab into a centimeter or two deep.

However, after these zombie animals mutated, they were at least more than three meters tall and at least five or six meters long, so such a small wound didn't matter to them at all.

And the other fire, water, earth, and so on, are also almost the same, and they can't cause any actual damage to these zombie animals.

However, this seemingly hard, impenetrable defense is vulnerable to Iyalan's spatial slicing ability.

With just a palm-sized spatial crack condensed, Iyalan could easily slice open the head of a zombie rhinoceros, leaving it dead to the point where it could no longer die.

It can be said that with Iyalan's attack, the entire southern city wall, this extremely threatening zombie animal, was all killed in just a few minutes.

Although Yi Yalan didn't shoot much, he played a role that even surpassed Xu Youcai.

This is the irreplaceable role of a top powerhouse in a war.

They may not be able to resist the tide of corpses, but with their strong combat effectiveness, they can solve some problems that the army cannot handle.

And obviously, Iyalan is such a strong man.

And the place where the four of them are located is the central position of the defense line, and with their mutual cooperation, they suppress the attack of the corpse tide, which will naturally cause some chain reactions.

Coupled with the existence of Xu Youcai and Yi Yalan, especially after Yi Yalan took action, and solved those top zombie animals one by one, the pressure on the entire defense line was directly reduced slightly.

Don't look like just a few, but it's a remarkable thing to do it in the middle of an eight-kilometre-long line.

Even this alarmed the high-ranking of the coalition army commanded on the southern city wall, the major general sent from Beijing City, came directly to Xu Youcai and others, and personally praised and encouraged him.

This kind of behavior certainly made Xu Youcai's vanity soar, and even killing zombies was more efficient.

However, Xu Youcai was also a little tired of this kind of behavior after killing for half an hour, after all, it had always been killing, killing, and killing again for him.

Therefore, Xu Youcai gradually shifted some attention to other aspects in addition to killing.

For example, the merit points he has accumulated.

The battle has been going on, so the merit points of each base are constantly increasing, and how many merit points have increased will be announced every half hour by the top of the coalition forces.

Although this will cause some trouble for the top level of the coalition forces, it also has its advantages, because this kind of long-term high-intensity battle can easily make people numb, and it is okay for a short time, but if it is long, there may be some mistakes.

It is undoubtedly a good choice to constantly stimulate the nerves of these soldiers with merit points, and it can also be regarded as a way to motivate morale.

And Xu Youcai has the privilege, and every five minutes, he will ask how much his merits have increased.

A person with an ability like Xu Youcai, and his contribution is still so great, the heralds at the top of the coalition army, of course, can't say anything because of this small request.

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

This kind of thing can be regarded as fun for a money fan like Xu Youcai.

Of course, in addition to the merit points, Xu Youcai also observed that this city wall has a rather interesting setting.

And this setting was suddenly discovered after he had been killing for a while.

Due to their constant killing of zombies, under normal circumstances, these zombie corpses fall under the city wall, and they will soon accumulate and pile up higher and higher.

Therefore, under normal circumstances, after killing zombies for a period of time, you need to set fire to the corpses to clean them up.

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

This immediately caught his attention, and with careful observation, Xu Youcai quickly discovered the secret.

It turns out that all this is because of a clever setting under the city wall, which was built at the bottom, not completely blocked, but left a "doorway" with a width and height of about two meters.

This "doorway" is usually blocked with rocks and cannot be seen at all, and only when the zombies attack for a period of time and the corpses pile up on the city wall, will this doorway be opened from the inside.

Since this doorway has been completely blocked by zombie corpses, even if it is opened, there is no need to worry, there will be zombies rushing in.

In this case, it is possible to safely pull the corpse from the outside in, and then quickly dissect it and take out the evolutionary flesh inside.

As for how to deal with the corpses of these zombie animals, Xu Youcai only learned after consulting the heralds beside him that they would transport these corpses to the northern city wall by truck, pour fire oil on them, and destroy them there.

The first point is to solve the problem of corpses, so as not to let the corpses of these zombie animals continue to accumulate and stack, so that these zombies can easily climb up, which is the most fundamental.

As for the second point, of course, you can get evolutionary meat, if you burn it directly with fire, then all the evolutionary meat inside will be burned, which will cause a great waste.

The third point is that you can use this endless stream of zombie corpses to form a wall of fire on the northern city wall to block the zombie attack over there, so as to save more troops to defend the other three city walls.

It can be said that such an approach is definitely a multi-task.

"It's really the right time to come here to the coalition forces this time, take this method back to the base to promote it, and then face these corpse tides in the future, it's like giving money!" Xu Youcai said with some excitement.

The herald who was in charge of recording Xu Youcai had a strange face, and he was excited when he saw someone mention such a corpse tide for the first time.

Don't you see that even if there are a million coalition troops here, it is not easy to fight? If it is a separate base, it is difficult to say whether it can withstand it.
