Even though the Devils had discovered the arrival of the Great Army, they could do nothing. There is no gateway to the Dwarven City from outside the mountains, or underground, and the battle between humans and the Devils is very auspicious, but on the ground, the Devils really have no advantage.

The claws and walking methods of the earth demons are all trained in the cave, they can walk 360 degrees from any plane of the cave without dead ends, appear from any angle and attack. But on the ground, the Earth Devil does not have such an advantage. It's also very powerful, but it's not the same as the situation underground.

Therefore, even if there are a lot of earth demons rushing out of the ground and facing the large army led by the egret, it will not cause any trouble at all, whether it is the lord's land demon or the general earth demon, it will only last for ten minutes at most, and it will be directly killed by the egret and others. Elizabeth, who is the most angry, doesn't even transform into a dragon's body, but uses a giant axe to attack, and the action of fighting is like a tornado.

Incarnate as a human body, the power of the dragon will not disappear, Elizabeth is an out-and-out humanoid tyrannosaurus, which is not something that the earth demon can resist at all, with such a pioneer existence, the temptation and attack of the earth demon has no effect at all.

The large army marched all the way, and under the guidance of Surabi, they soon arrived at the gate of the original dwarf city, but unlike before, the gate of the dwarves was actually sealed by a huge rock, and it was impossible to enter and exit at all. The gate of the dwarf city is a magnificent cave entrance, which is a boxy, more than thirty meters high and more than ten meters wide, but now, it is sealed by a large rock, and it feels like you can't enter it from any angle.

"It's really funny. The egret looked at the rock with amusement, "The earth demon actually knows how to close the entrance and exit, so as to buy time. However, I don't really want to go in and engage in some kind of underground war with those goblins. ”

In front of the gate of the dwarf city, it is actually an open mountain cliff area, which is as large as several square kilometers, and the 70,000 troops of the human race are completely standing, and the egret does not want to enter the dwarf city at all, and fight a head-on battle underground, to put it mildly, it is the territory of the dwarf and the earth demon, even if there are more human beings, going to the environment of the opponent's home field is just looking for death.

However, the earth demon is not an idiot, the other party will not abandon its own advantages and run out of the ground to fight with humans on the ground, but for this, the egret has long had a plan.

"Sky Hunting Incendiary Bomb, isn't that a powerful incendiary bomb in the mecha world, what are you going to do with this?" Tu Miaoyou asked a little puzzled. Since just now, the egret has been constantly taking out incendiary bombs from its personal space, and now dozens of boxes have been piled up on the flat ground. You must know that this incendiary bomb is not an incendiary bomb used against humans, but against the starry sky beast, it is a weapon used by mechas, although the explosion range is not large, but it can produce extremely strong high temperatures in a small area, which is a very powerful weapon.

"The power of the incendiary bomb, but it can't break this rock, first of all, the attack rules are not very conformable, this world will limit the power of the explosion, and the attack on the rock has a very poor effect. No matter how much you prepare, it's useless. "Qin Yu is also very familiar with this incendiary bomb, she and Tu Miaoyou have cooperated a lot, and they also used the incendiary bomb to deal with the Starry Sky Beast together.

In the case of being familiar with the rules of this world, everyone knows that the attack forces of other worlds actually play a small role here, although the basic rules are similar, but the judgment and reaction at the level of destruction of this world seem to have a layer of separation, and the power that does not belong to the rules of this world will be completely resisted. It's like a self-judgmental resistance mechanism. Qin Yu knew very well that even he could see through the changes in this rule, and it was impossible for the egret not to be clear.

"It's because incendiary bombs can't blow up rocks, or even destroy the gates of a dwarven city or any of the passage buildings, that I chose this thing. The egret suddenly sneered, "I'm not an idiot to push away the rocks and kill them all the way to the other party's lair." It's underground, and there is the opponent's territory everywhere above and under the feet, and the opponent can attack from wherever he wants. ”

"Even if we have two kings and more than thirty high-level professionals, how many of the 70,000 troops here can we take care of? ”

"Even if you're right. But it's useless for you to take out so many incendiary bombs from the mecha world. Qin Yu covered his forehead, "If this kind of weapon is useful, we still need to fight monsters so troublesome and upgrade?"

"I didn't say that this thing was used directly against the Earth Demons. Without saying anything, the egret asked Elizabeth to push a crack in the rock, and then asked the troops to help, and began to throw a large number of incendiary bombs from the egret's way into the dwarf's gate.

The door of the dwarves and the road of wealth, plus the city of the dwarves, because this space is underground, even if there are tens of millions of cubic meters of space, this is also an underground space, speaking of which, it is like a natural bottle, in a bottle, all things are limited, and the most limited is air. Oxygen is needed for combustion, which is inevitable, and even the world itself cannot change this basic rule. No matter what kind of organism it is, it cannot leave oxygen, which is the principle of existence of carbon-based organisms.

No creature in this world can leave this basic living condition, they may be able to resist the heat with their physique, but they are absolutely unable to resist the absence of air, the vacuum is the natural enemy of almost all living things, even the monsters of this world.

The egret didn't care about the demon reaction at all, and after throwing the incendiary bomb into it, Elizabeth pushed the rock up again, sealing the door again. Immediately, the egret detonated the incendiary bomb on the spot, just like Qin Yu said, the incendiary bomb that can blow up the building with its own explosive ability, and even the dwarf's gate and sealed rock can't be exploded, just a slight shock, but there is no reaction.

"What's the use of this?" Qin Yu still didn't understand, and asked as he looked at the egret with a curious expression.
