This new zombie can be called a "tank".

Because, his body is very large, like a real fat man.

Logically speaking, fat will be attacked by a larger range and should be more likely to be killed.

But no one knows what structure is inside this tank zombie. It is extremely fleshy and extremely difficult to kill.

Fortifications that could solve other zombies, but when they encounter such tanks as the leader, they begin to show signs of loosening.

Xue Wang immediately demolished the building behind the wall, like during a forest fire, cutting off the surrounding books and clearing out an isolation belt.

Then, Xue Wang did the second thing, which was to build a new wall and gather all the mobile suits and snipers from other directions.

At the same time, order snipers already on the wall to give priority to sniper tanks.

"Bang!Bang!Bang!"

"Bang!Bang!Bang!"

"Bang!Bang!Bang!"

“…”

The snipers sniped again and again, and the black blood had already turned the earth black.

The intensive attacks of the snipers finally knocked down the tank.

However, the zombies behind him rushed forward and destroyed the wall.

The snipers on the wall fled the wall that had begun to collapse as quickly as possible, pulled up the second line of defense that had just been cast, and continued to defend on this line of defense.

Fighting is never a hot blood, and it is never a tense and exciting thing.

All snipers can feel is numbness.

Pull the bolt, shoot, and kill the zombies.

That's all they can do.

However, for the thousands of residents behind them, they could only continue to fight.

One shot after another.

One shot after another.

At the same time, Xue Wang began to develop more advanced technologies.

Yueliangjing Technology is just the pre-technology to reach the next technology.

The next technology, the troops that can be produced, are even more powerful.

Before this, whether it was a militia, a mobile suit, or a sniper, they were all units of single attack. No matter how strong the attack power was, they could only attack one enemy at a time.

As more and more enemies are involved, the effectiveness of such single-body attacks will of course gradually weaken.

Therefore, units that can attack in groups are imperative.

The first new recruit, Xue Wang chose "Death".

The characteristic of the Death Warrior is that it can fire air cannons. When the air cannon can attack a large number of enemies, it can also produce a knockback effect.

Even a brief repulsion can relieve the pressure on the city wall.

In comparison, another unit, Lucifer, is also a range attack, but its attack method is to spray a large amount of oxygen.

Compared with the God of Death, this is not very helpful to Xue Wang's current situation.

Of course, these troops are only auxiliary functions.

Manpower is always limited. If you want to be able to defend properly in all directions, it is best to use defensive machines to defend.

Although the crossbow arrow tower was a magical tool in the early days.

But gradually, so many zombies cannot be cleaned up.

Therefore, the defense machine also needs to be upgraded. Xue Wang did not choose to upgrade the machine gun tower to upgrade the crossbow arrow tower, but chose another brand new direction "Shock Wave Tower" for research and development.

The oscillation tower can release an oscillation wave, which can cause huge damage to all zombies in the range.

As for the principle, Xue Wang dared not speculate.

However, he had an idea in his mind. He doubted this principle, which was probably similar to finding the frequency of their fluctuations from zombies, and then using an extra frequency to destroy them all.

If it is this attack mode, Xue Wang feels that his voice shape can also be copied.

However, the first thing you need to do in the shape of sound is to keep the oxygen that Xue Wang breathes constant.

Because the oxygen here is now produced by base vehicles and moon wells.

Therefore, the concentration of oxygen fluctuates greatly.

Those long-eared people may have adapted to this fluctuation.

But for Xue Wang, if the oxygen is too thin, they will produce altitude sickness. If the oxygen is too rich, they will produce an oxygen-rich reaction.

In short, it’s not enough to do more or less. Only when you can continue working can you continue to work.

The oscillation wave tower was successfully developed!

The construction of the oscillating wave tower was successful!

The appearance of the oscillating wave tower does not look particularly strange, it looks like a giant short and chunky insecticide spray bottle.

In fact, it is indeed a bottle, an oxygen bottle.

After a period of oxygenation, a large amount of oxygen will be gathered inside.

Then, when a zombie reaches its attack range, he will spray the compressed oxygen out at a very strange frequency.

This makes oxygen become like a scalpel, which can easily enter the zombie's body and then explode.

A zombie, in the shock wave tower, was like a trillion knives inserted into it and exploded.

In an instant, it turned into a pool of meat paste.

Not even bones left.

Originally, Xue Wang thought that the oscillating wave tower was in the form of earthquake waves, spreading fluctuations, thus destroying and disappearing the zombies.

Unexpectedly, it was a can of large "zombie killing spray". Although Xue Wang could also imitate this function in the form of sound.

However, compared to seismic waves, it is still too complicated.

Seismic waves, Xue Wang can even maintain uninterrupted operation now.

As for this spray, Xue Wang also needs energy storage.

Energy storage for ten minutes and attack for one second.

If you want to attack continuously, Xue Wang may need 599 gas cylinders to inflate continuously.

If Xue Wang had such a control scale and control intensity for the shape of sound, he felt that he would not have to farm anymore.

One person can overturn the zombies on the moon.

Unfortunately, he didn't.

Moreover, he didn't know when he could improve the level of sound form.

Originally, he thought that using the shape of sound continuously could make the shape of sound stronger.

Even so, the strength of the sound form is only because Xue Wang has stronger control ability, not because the total amount of the sound form is larger.

It seems that if you want to upgrade next time, you can only wait until you open the treasure chest.

Xue Wang wanted to get the task conditions for opening the next treasure chest, and then became more devoted to entering the working state.

Five thousand.

Ten thousand.

Twenty thousand.

Thirty thousand.

Before we knew it, the number of people at the base had increased to 30,000.

The entire urban area is now not enough to be able to see it at a glance.

As the area expanded, the attack became more and more fierce.

However, with the increase of personnel and the development of technology, the difficulty of defense has not become increasingly greater.

This is a lucky thing for the entire base.

However, the old rabbit told Xue Wang about something that was not very lucky.

"There is a corpse king in the south. We are close to its range of movement and he may attack us at any time. If we do not want to be attacked in other directions and are also attacked by him, we will attack him first."

"What is its approximate value."

"Ten thousand blood."

"Ten thousand blood?" Xue Wang suddenly scratched his head.
