When Wang Hao was on Earth, he had heard of a weapon called a cloud burst bomb. Pen, fun, and www.biquge.info

Once it explodes, it burns violently, and then quickly consumes the surrounding oxygen, suffocating all enemies within range, even the strongest cover cannot withstand the lethality of the cloudburst bomb.

This kind of weapon makes people feel terrifying when they hear it, but Wang Hao never thought that his Huacheng would actually face such a danger.

At the beginning, when the fire wall was set up, Wang Hao personally tested the temperature of the fire wall on the city wall to see if it would cause harm to the soldiers on the city wall.

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

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

Originally, the walls of Hwaseong were thousands of meters long.

Even if the oxygen is partially consumed by the flame, it can still be replenished from high altitudes.

However, the pressure is different now, and when the air inside Hwaseong is constantly being consumed, the air outside cannot come in, which makes Hwaseong fall into a crisis.

Look at the fleeing beasts outside the city.

Wang Hao knew that he was about to succeed in defending the city.

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 that his intestines were full of regret.

If he knew that this was the case, he would not have brought Wang Bin with him anyway.

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

Wang Hao knew that now the city was only because of the fire wall, which formed a special air pressure, so that the outside air could not enter, just like a round balloon.

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

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

It doesn't need to be too long, just open a gap of twenty or thirty meters in the wall of fire.

Thinking of this, Wang Hao hurriedly ordered the surrounding soldiers to gather all the black crystal bombs and bomb them at a point, and be sure to destroy all the fire oil on the ground at that point, so as to open up a way out for Huacheng.

Although the soldiers couldn't understand why Wang Hao asked him to break through the wall of fire that guarded Huacheng, since it was Wang Hao's order, it must be nothing wrong, so they all did it.

One after another, the black crystal bombs were aimed at one point and bombarded.

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

Then the ground was also lifted, and finally the oil on it was blown into the very dry earth that had been baked.

It's just that when the Black Crystal Bomb just exploded, the flames were suppressed a little.

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

The soldiers were all panting, 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 that had just arisen from the imminent victory of the Great War was gradually replaced by a feeling of dizziness.

And the lack of oxygen made the soldiers feel like they were seriously ill.

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

Unless there is a rainstorm now!

However, since the sunny morning weather, there has been no sign of rain.

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

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

However, outside Hwaseong, not to mention the herds of beasts that have not yet gone far and are still surrounding Hwaseong a few hundred meters outside the city.

The mere wall of fire with no dead ends outside the wall made it impossible for the clansmen to get out.

What's more, as oxygen becomes less and less, the physical fitness of the fighters is getting worse and worse, and they can't run out when the time comes.

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

He hurried to the bell and struck it seven times in succession.

These seven bells are ringing to convey a special command. It was an order about the back hand that he left behind.

Not long after the bell rang, Wang Lung, whose face was flushed red, led a few people to carry a huge firecracker onto the city wall.

"Hao, big... Something is wrong with everyone! Be... Isn't it... Poisoned? Wang Lung said to Wang Hao while arranging for someone to place the big firecrackers.

"We're starved of oxygen! You go and tell everyone that if you feel unwell, stay where you are and don't do strenuous exercise. If you faint, lift them inside. Wang Hao responded to Wang Long and lit this huge firecracker.

"Lack of oxygen?" Wang Lung frowned and thought about it, it seemed that he had heard Wang Hao say this word before, but he had already forgotten what it was.

However, he didn't ask much, 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, their eyes are full of stars, and they are weak and then gradually paralyzed on the city wall.

If at this time, the flock of birds comes in and makes another raid. That Hwaseong Castle will definitely be lost.

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

This special firecracker, which was ignited by Wang Hao, flew into the sky.

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

Huge firecrackers exploded in the air, exploding a field of colorful fireworks.

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

Two kilometers away from Hwaseong.

When the two black-armored soldiers who took turns guarding a tree house day and night saw the firecrackers in Hwaseong, they hurriedly took out a firecracker from the tree house that was very similar to Wang Hao's firecracker, and then lit it.

Two kilometers away, on a hill, a black-armored soldier saw fireworks exploding in the direction of the treehouse, and then took out a firecracker from the cave.

In this way, Hwaseong's order was conveyed in the distance in this form of fireworks relay until it reached the depths of the Black Forest, beside the two large mountains that had been blown up by gunpowder.

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

Even though he 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 motionless for a long time.

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

Although so far, there has been no information in the sky about the failure of Hwaseong to defend the city.

But thinking of the herd of beasts that kept running past him in the past few days and rushing towards the direction of Hwaseong, Wang Hu was a little worried about the situation in Hwaseong.

But fortunately, although there were more beasts going to Hwaseong, at least the group of giant treemen with a height of 100 meters did not make it to Hwaseong.

Although they are huge and have the power to pull mountains, their speed is too slow.

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

But they're smart.

I know that there are too many trees in Hesse, and it is not easy to walk.

Now, many of them walk along the bed of the large river that has dried up.

Although the muddy riverbed has a layer of silt several meters thick, it is nothing for their 100-meter-tall size.

Now, seeing these strangely shaped tree people, Wang Hu finally knew why every black armor army who went to explore the Black Forest could not come back alive once they entered the depths of the Black Forest.

There was such a horrible group in the depths of the Black Forest, and it was surprising that they were able to come back.

Just as Wang Hu's thoughts were flying and thinking about things, in the distance, a firecracker exploded, and the brilliant brilliance lit up the gloomy sky.

Wang Hu rubbed his eyes, and after making sure that he was not mistaken, he hurriedly shouted: "Come to order!" Hwaseong let us release the water! ”

Listening to Wang Hu's loud call, the black-armored soldiers came out from everywhere one after another.

In fact, there is no need for Wang Hu to remind them, they also saw firecrackers in the distance. For fear of missing the order, Wang Hu ordered all the black-armored troops to divide into two groups to observe from all angles.

Subsequently, a torch was handed to Wang Hu by a black-armored soldier.

Wang Hu took the torch and pointed at the fuse beside him, which was covered by a wooden board to prevent water from entering.
