It's 100 kilometers from where the people are to the bottom of the fortress.

However, with the continuous collapse and subsidence of the fortress, a drop of more than 3000 meters has been formed.

Although the inclination is not too big, Chu Feng specially made a curved slope of the ground in front of him. The length of the slope is only 10 kilometers, which can be used as a bowling alley.

However, they need to wait for the demons to come here.

Chu Feng took out some huge balls from the space, about one meter in diameter, and put them on the ground, saying: "this is a metal hydrogen bomb, in which some special bombs are mixed. When these demons rush, we can try to play."

People in the military support Chu Feng's evil taste from the bottom of their hearts.

For the earth, the demons are the invaders. The demons captured by the city of dawn will not give a good face. What's more, the demons who cut off the passage between the two continents?

It is also an irresistible temptation for them to play with these demons.

However, the discipline of the military makes them dare not act rashly.

What's more, they still have doubts about the usefulness of these things made by Chu Feng.

In the past two months, metal hydrogen bombs have entered the era of mass production, but in the process of putting them into use, they still need to cooperate with the weapons of the past.

It's better to use a shell launcher, even an old-fashioned mortar, than to throw it by hand.

In the distance, a large number of demons have been desperate to kill them.

Both Maoxiong's military and Huaxia's military are ready to fight to the death.

They have enough confidence, but it doesn't mean they can take the enemy lightly.

In the face of this enemy who can cut off the passage between the two continents, we can not be too cautious.

See the military said that the dawn of the city members do not want to do first.

"You see me demonstrate it first."

Seeing more and more demons rush out from the ruins of the fortress, Chu Feng pushes an iron ball forward without any throwing action.

Some people are puzzled. It's easy for the strong man of level 7 to throw out an iron ball with a diameter of one meter. Why should he throw it out like this?

Soon, their doubts were answered.

The iron ball slipped from the top of the curved slope and began to accelerate.

But this acceleration process violates the rules of gravity.

When the height of the ball was only 100 meters, everyone had heard the sound of explosion.

Obviously, this iron ball has broken through the speed of sound.

"Well, what's going on?"

"Did Chu Feng just inject Yuan Li into it?"

"Is it necessary to do so much?"

"I don't know. Maybe it's Chu Feng's bad taste."

We are all people who have received nine-year compulsory education. It is difficult to explain such a scene. Fortunately, we have entered an era of fantasy, and the scientific system has collapsed in half. We are not totally unable to accept it.

The iron ball quickly crossed the slope of 3 km and 10 km, and entered the ranks of the demon army. The demon army was covered with Yuanli, ready to use Yuanli to resist the explosion.

They are certainly on guard against the lessons of the silver phosphorus demons.

Level 7 masters, as long as they use Yuanli to resist in advance, even nuclear bombs can resist, provided they don't enter the nuclear explosion center.

However, with the reaction of level 7 experts, if you want to enter the nuclear explosion center, you must be releasing water.

How can these demons not react to such a long distance?

The power of a metal hydrogen bomb is smaller than that of a nuclear bomb. Even a level 6 master has a chance to save his life as long as he leaves the center of the explosion.

Therefore, even if the metal hydrogen bomb is 50 times stronger than the TNT bomb of the old era, it can only be used as an ordinary shell in the new era. After all, the enemy is too strong.

"Bang!"

Under the slope, there is no mushroom cloud that people expect.

The huge iron ball suddenly burst open. Countless small iron balls appeared from the huge iron ball and flew away in all directions. After meeting the enemy, they immediately became a small mushroom cloud.

One after another, explosions were heard on the ground below the slope.

Under the slope, the fire blazed into the sky.

In the past, hundreds of demons were killed on the spot and thousands of them were killed.

"Is this the new bomb you're working on?"

Luo Xingyao frowned, "I didn't mean to hit you, this kind of bomb is a little small."

Regardless of any product, the most important thing is practicality.

This kind of bomb looks very handsome. A huge bomb is attached with many small bombs, but it is much worse than many small bombs which are fired continuously by mortars.As long as the other side is on guard, this kind of shell will be useless the second time.

"Look carefully!"

Chu Feng did not explain too much, but continued to throw the iron ball down.

The demons had suffered a big loss just now. When the second iron ball fell, most of the demons immediately backed away, but a small part of the demons rushed towards the iron ball.

This is to sacrifice a small part of the demon clan and reduce casualties for the large army.

At this moment, the big troops just ran a few steps to both sides, and suddenly turned back, as if they could never leave a fixed range.

The deafening sound, accompanied by the sky fire, drowned thousands of demons.

Seeing this, the master's face changed.

Chu Feng didn't show them the power of the new bomb at all just now. What they showed them was the power of the slope.

The follow-up demons arrived at the slope and wanted to rush up to the human gathering place on the slope, but no matter how hard they tried, they could only turn around in the same place, as if they had encountered a ghost hitting the wall.

In the continuous roar of the explosion, the slope seems to form a strange circle.

As long as this strange circle constantly causes bombs, it will certainly cause casualties. As long as the demon people pass through the strange circle, they can't leave. If they want to bypass the strange circle, they can't help walking.

The officers of the two countries ordered the soldiers to fire, and shells made of metal hydrogen bombs kept roaring out.

When these shells leave the muzzle, the speed will suddenly speed up to a point contrary to common sense, which makes people unable to react at all. According to reason, it should be very difficult to aim at such an extraordinary speed.

But they don't have to aim, as long as it's toward the outer ring, it will fall on the demons.

The gunfire roared and the bodies were everywhere.
