From where everyone is, to the bottom of the fortress, a total distance of 100 kilometers.

However, as the fortress continues to collapse and sink, a drop of more than three kilometers has been formed.

Although the inclination angle is not too great, Chu Feng deliberately made an arc-shaped **** on the ground in front of him. The length of the **** is only 10 kilometers, which can be used as a bowling alley.

It's just that they need to wait for the demons to come here.

Chu Feng took out some huge spheres, about one meter in diameter, and placed them on the ground, saying: "This is a metal hydrogen bomb, with some special bombs mixed in. When these demons rush over, we You can try to play."

The people in the military support Chu Feng's evil taste in my heart.

For the earth, the demons are the invaders. The demons captured by the City of Dawn will not give a good face, let alone these demons that cut off the two continents?

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

However, the discipline of the military prevents them from acting rashly.

Besides, they are still skeptical about the usefulness of these things made by Chu Feng.

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

Using a cannonball launcher, even an old mortar, is better than throwing it by hand.

In the distance, a large number of demons had already killed them desperately.

Whether it is Mao Xiong's military or China's military, they are all ready to fight to the death.

They have enough confidence, but it does not mean that they can take the enemy lightly.

In the face of this enemy who can cut off the passage between two continents, no matter how cautious it is.

I have seen military officials say that the members of the City of Dawn don’t even bother what to do first.

"Let me demonstrate it first."

Seeing more and more demons rushing out of the ruins of the fortress, Chu Feng just pushed an iron ball forward without any throwing action at all.

Everyone was a little puzzled. For the 7th-tier powerhouse, it is easy to throw out an iron ball with a diameter of one meter. Why should it be thrown out like this?

Soon, their doubts were answered.

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

But this acceleration process violated the rules of gravity.

When the height of the iron ball fell only 100 meters, everyone had heard the sonic boom.

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

"Well, what's going on?"

"Could it be that Chu Feng injected vitality into it just now?"

"Does it take so much to do this?"

"I don't know, it might be Chu Feng's evil taste!"

Everyone has gone through nine-year compulsory education. It is difficult to explain such a scene, but fortunately, we have entered the age of fantasy, and the scientific system has collapsed in half, and everyone is not completely unacceptable.

The iron ball quickly traversed a **** of up to 3 kilometers, and a **** of 10 kilometers long entered the queue of the demon army. The demon army's body surface was covered with Yuanli, ready to use Yuanli to resist the explosion.

There have been lessons from the Silver Phosphorus Demon Race, and of course they are prepared.

As long as Tier 7 masters use Yuan Li to resist in advance, they can resist even nuclear bombs, provided that they do not enter the center of the nuclear explosion.

However, with the response of the 7th-level master, if you want to enter the center of the nuclear explosion, it must be water.

How could these demons fail to react at such a distance?

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

Therefore, even metal hydrogen bombs that are 50 times stronger than the TNT bombs of the old era can only be used as ordinary shells in the new era. After all, the enemy is too strong.

"Boom!"

Under the slope, there was no mushroom cloud that everyone expected.

The huge iron ball suddenly exploded, and countless small iron **** appeared from the huge iron ball, and flew in all directions. After encountering the enemy, it immediately turned into a small mushroom cloud.

Successive explosions sounded continuously on the ground below the slope.

Beneath the slope, the flames skyrocketed.

After this round of explosions, hundreds of demons have been killed on the spot, and thousands of demons have been injured or killed.

"Is this the new type of bomb you are studying?"

Luo Xingyao frowned, "I didn't mean to hit you on purpose. This kind of bomb is a little less useful."

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

This kind of bomb looks very handsome. A huge bomb has many small bombs attached to it, but it is still a lot worse than many small bombs fired by mortars.

As long as the opponent is prepared, this shell will be useless the second time.

"watch carefully!"

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

The Demon Legion suffered a big loss just now. When the second iron ball fell, most of the Demon Race immediately pulled away and retreated, but a small part of the Demon Race actually rushed in the direction of the iron ball.

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

At this moment, those large troops just ran a few steps to both sides, and suddenly turned back, as if they would never be able to leave an established range.

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

Seeing this, the master's face changed.

Chu Feng was not just trying to show them the power of the new type of bomb, what they showed everyone was the power of this slope.

Subsequent demons continued to reach this **** and wanted to rush from here to the human gathering place on the slope, but no matter how hard they tried, they could only spin around in place, as if they had encountered a ghost hitting a wall.

In the constant roar of explosions, a strange circle seemed to form under the slope.

As long as this strange circle keeps causing bombs, it will definitely cause casualties. As long as the demons pass through that strange circle, they cannot leave. If they want to bypass the strange circle, they will also involuntarily walk over.

The officers of the two countries ordered the soldiers to fire, and the shells made of metal hydrogen bombs continued to roar and fly out.

When these shells leave the muzzle, the speed will suddenly accelerate to a point that violates common sense, making people unable to react at all. It stands to reason that such speeds beyond common sense should be difficult to target.

But they don't need to aim, as long as it is a cannonball sent in the direction of the outer circle, it will definitely fall on the demon.

The artillery roared, and the corpses were everywhere.
