Primitives are stunned

Chapter 638 Treant and Water Release

When Wang Hao was on Earth, he had heard of a weapon called Cloud Bomb.

Once it explodes, it will burn violently, and then quickly consume the surrounding oxygen, suffocating the enemies within the range to death, no matter how strong the bunker is, it cannot resist the lethality of the cloud bomb.

This kind of weapon sounds terrifying, but Wang Hao never thought that his Huacheng would face such a danger.

At the beginning, when the firewall was set up, Wang Hao personally tested on the city wall whether the temperature of the firewall would cause harm to the soldiers on the wall.

It turned out that because the flames were blocked by the city walls, they would not hurt the people on the walls.

But Wang Hao never thought that when a circle of flames burns around Huacheng, the air pressure inside the fire wall will be different from that outside the fire wall, and all the air will be blocked outside, and it will not be able to enter at all.

Originally, the city wall of Hwaseong had a span of thousands of meters.

Even if part of the oxygen is consumed by the flames, it can still be replenished from high altitude.

However, the pressure is different now. While the air inside Hwaseong is constantly being consumed, the outside air cannot get in. All of a sudden, Hwaseong is in crisis.

Looking at the herd of beasts fleeing in a hurry outside the city.

Wang Hao knew that defending the city by himself was about to succeed.

But it never imagined that in the end, it might die in the city due to lack of oxygen.

Thinking of this, Wang Hao felt regretful in his gut.

If he knew this was the case, he would never have brought Wang Bin with him anyway.

He was still a child, how innocent he would be if he died here like this.

Wang Hao knew that because of the wall of fire, a special air pressure was formed in the city, preventing the outside air from entering, just like a round balloon.

When there is no gap, the air inside the balloon cannot come out or go in.

However, as long as a gap can be opened, the air pressure will be broken, and oxygen can naturally come in.

It doesn't need to be too long, just open a gap of 30 meters in the firewall.

Thinking of this, Wang Hao quickly ordered the surrounding soldiers to gather all the black crystal bombs and aim at a point for bombing. Be sure to blow up all the kerosene on the ground at that point, and open up a way out for Huacheng.

Although the soldiers couldn't figure out why Wang Hao asked him to break through the firewall guarding Huacheng, since it was Wang Hao's order, there must be nothing wrong with it, so they all followed suit.

One after another, the black crystal bombs aimed at a certain point and bombed down.

Where it was bombed, the charred corpse of the beast was first blasted up.

Then the ground was lifted up, and finally the kerosene on it was blasted into the baked very dry soil.

It's just that when the black crystal bomb was just blown up, the flames were suppressed a bit.

But after the kerosene black crystal bomb was blown up, the bombed area burned more vigorously because of the new oxygen.

The soldiers were panting heavily, and they all felt that they were already trying to breathe, but for some reason, they still felt a little out of breath.

The excitement just now because of the imminent victory of the war was gradually replaced by the feeling of dizziness.

And the lack of oxygen made the soldiers feel weak all over, as if they had suffered a serious illness.

Wang Hao looked at the wall of fire outside the city, racking his brains but couldn't think of any way to extinguish it.

Unless there is a heavy rain now!
However, there has been no sign of rain since the morning.

What's more, once it rains, the rain destroys the pressure inside Hwaseong, and the fire wall doesn't need to be extinguished to allow oxygen to come in.

Wang Hao even thought of a way to leave the city immediately.

However, outside of Huacheng, let alone the herds of beasts that have not yet gone far, and are still surrounding Huacheng a few hundred meters outside the city.

Just the firewall with no dead ends outside the wall made it impossible for the clansmen to get out.

What's more, as the oxygen is getting less and less, the physical fitness of the soldiers is getting worse and worse, and they will not be able to run out by then.

Wang Hao, who was racking his brains, suddenly had a flash of inspiration and thought of a way.

He quickly ran to the big clock and rang seven times in a row to the big clock himself.

The seven bells were rung to convey a special order.It was an order about the henchmen he left behind.

Not long after the bell rang, Wang Long, whose face was flushed, led a few people and carried a huge firecracker up the city wall.

"Hao, everyone feels something is wrong! Is...is...poisoned?" Wang Long said to Wang Hao while arranging for people to put the big firecrackers in place.

"We're out of oxygen! Go and tell everyone that if you feel unwell, stay where you are and don't do strenuous exercise. If you faint, help them inside." Wang Hao responded to Wang Long while igniting the fire. Huge firecrackers.

"Hypoxia?" Wang Long frowned and thought about it. It seems that Wang Hao has heard this word before, but he has already forgotten what it is.

However, he didn't ask too many questions, but went to deliver the news according to Wang Hao's instructions.

On the city wall, because the oxygen is getting thinner and thinner, more and more people are dizzy in front of their eyes, staring at their eyes, feeling exhausted and gradually slumping on the city wall.

If at this time, the flock of birds came in to make another surprise attack.That Huacheng will definitely fall.

Of course, birds are most sensitive to changes in air pressure. At this time, it is absolutely impossible for them to enter Hwaseong, because entering Hwaseong at this time, in their view, is no different from courting death.

The special firecracker lit by Wang Hao flew into the sky.

The firecrackers charged three times flew higher than the rest of the firecrackers.

Huge firecrackers exploded in the air, blasting out a colorful firework.

In such drowsy weather, the flames produced by the explosion can be clearly seen by people far away.

In a place two kilometers away from Huacheng.

Two black armor soldiers who took turns guarding a tree house day and night saw the firecrackers in Huacheng, and quickly took out a firecracker similar to Wang Hao's firecracker from the tree house, and then lit it.

And on a hill two kilometers away, a black armored soldier saw fireworks exploding in the direction of the tree house, and then took out a firecracker from the cave.

In this way, Huacheng's order was conveyed to the distance in this way of fireworks relay, until it reached the depths of the Black Forest, beside the two mountains that were blasted by gunpowder.

Standing on a mountain, Wang Hu looked in the direction of Hwaseong worriedly.

Although it was too far away to see anything, he still looked at it like this.

Since completing the task, Wang Hu has been looking at the direction of Hwaseong for a long time without moving.

Not for anything else, he was just afraid that if he missed the order from Hwaseong.

Although so far, there is no information about the failure of Hwaseong's defense in the sky.

But thinking of the herd of beasts running past and rushing towards Huacheng these days, Wang Hu was a little worried about the situation of Huacheng.

But fortunately, although there are more beasts going to Hwaseong, at least the group of giant treants with a height of [-] meters failed to rush to Hwaseong.

Although they are huge in size and have the power to lift mountains, their speed is really too slow.

After walking for so long, they are still in Wang Hu's sight.

But they are pretty smart.

Knowing that there are too many trees in Hessen, it is not very easy to walk.

Many of them now follow the beds of great rivers that have dried up.

Although the muddy riverbed has a layer of silt several meters thick, it is really nothing compared to their bodies that are hundreds of meters high.

Now, after seeing these grotesque treants, Wang Hu understood why none of the black-armored soldiers who went to explore the Black Forest could come back alive once they entered the depths of the Black Forest.

There is such a group of terrifying things in the depths of the black forest, it is surprising that they can come back.

Just as Wang Hu was thinking about something, a firecracker exploded in the distance, illuminating the gloomy sky with brilliant brilliance.

Wang Hu rubbed his eyes, and after making sure he read it correctly, he quickly shouted: "Here comes the order! Huacheng told us to release the water!"

Hearing Wang Hu's loud call, the Black Armored Army came out from everywhere.

In fact, without Wang Hu's reminder, they also saw the firecrackers in the distance.In order not to miss the order, Wang Hu ordered all the Black Armored Army to divide into two groups to observe from all angles.

Then, a torch was handed to Wang Hu by a black armor soldier.

Wang Hu took the torch and pointed at the lead wire that was covered by wooden boards to prevent water from entering.
