The reason it has this idea is that the behavior of the road troops and others is too obvious, that is, they are forcing them to go out for a decisive battle.

Although Lord Xueyan is not extremely intelligent, it's easy for Ni Duan to see this.

Since the Route Army and others think that way, it just doesn't follow, so that the Route Army and others can't achieve their goal.

So the next moment, the Lord of the blood rock issued a death order to make the blood rock creatures hold their breath and not inhale too much dust and smoke.

If you really can't hold it, just stretch your head to the window for a breath. The air there is OK.

Anyway, now as long as they can withstand the pressure and last for more than ten minutes, the road army and others will be absolutely helpless.

At that time, their reinforcements will come from afar, and it will be their turn to fight back, Lord Xueyan thought fiercely.

After receiving the order from the Lord of blood rock, the blood rock creatures can only choose to comply.

Now it's impossible for them to fight. They can only live in a place with less dust and smoke.

Seeing that there were no blood rock creatures coming out at the entrance of the tower, Lu Jun and Xiao Wan frowned deeply.

Because it means that their plan failed, Lord Xueyan didn't come out, and they couldn't carry out the next step.

"How can it be? Are those grenades not working on this plane? I haven't come down for such a long time. I shouldn't... " The passers-by murmured bitterly, and their eyes never left the tower.

"Indeed, the internal environment of the tower is very suitable for the implementation of this scheme. As long as we start throwing grenades from the top floor and let these monsters have no way to go, they will definitely come out."

"My only worry is that these grenades may not have any effect on the blood rock clan. After all, they are creatures of other planes."

"And it's also a problem how we defend them when they come out. We may not be able to defend if too many creatures come out all of a sudden." Ruan Bing's tone beside her was very worried. It seems that she has taken all the points that are easy to be ignored into consideration.

"Well, what you said is very reasonable, and I agree with you very much, so we have to try it anyway, and the sooner the better." The passer-by nodded, "as for the defensive method, don't worry too much about it. Just bring them out."

In fact, the army is not very afraid of all the blood rock creatures coming out, because there are a lot of dinosaurs in the army.

The more enemies there are, the better his dinosaurs will play, so the road army is not worried at all now.

While saying this, the army took out a large number of special grenade bags from the armed module and threw them into Ruan Bing's and Xiaowan's hands: "I'm not enough alone. You should come along. We'll try our best to make this tower full of smoke and poison gas in one minute."

"In addition, you should also make Lin Yilan and Ruan Xue ready to bear the impact. The battlefield may be in chaos later."

"I understand."

I see.

Xiaowan and Ruan Bing nodded one after another and had no objection to the order of the army.

Seeing that everything was ready, the army took the lead in flying to the tower, while Ruan Bing and Xiao Wan dispersed in different directions.

Ten seconds later, the soldiers came to the top of the tower. Without thinking about it, he threw a green grenade and a white grenade into it.

The full names of these two things are dust and poison. The effect is to spray powder and release poison.

Powder is used to prevent any creature from breathing. If you inhale this kind of thing, it will be very uncomfortable and sneeze all the time.

The toxic effect is to suppress the nervous system of any creature, to make them hallucinate, to lose judgment and so on.

In any case, these two kinds of grenades have strong diffusibility, which is enough to achieve the effect thought by the soldiers.

When the two special grenades enter the top of the tower, they immediately become blurred and can't see anything clearly.

At the same time, there is powder and smoke, which makes people feel sick from a long distance.

Seeing that the whole top floor was blocked, the soldiers were very satisfied. They flew to the next floor and repeated the action just now.

Xiaowan and Ruan Bing also arrived at the bottom of the tower at this time to take charge of the floor where they need them.

Although inside the tower is a blood rock creature with weapons, it looks very dangerous.

But in fact, Lu Jun and others don't have to go in. They can just throw all kinds of grenades into the small opening of the tower. No matter how many blood rock creatures there are, they can't help it.

The commander of Xueyan in the tower also knows that the soldiers are around the tower, but he doesn't know what these people are doing

A few minutes later, the whole floor of the tower was filled with dust and green smoke, which also means that the initial goal of the soldiers was achieved.

Especially on the floor where the blood rock creature and the blood rock Lord are located, they throw three times more grenades.

Then they all rushed back to the bottom of the tower, reorganized the team and made a defensive posture.

Now they don't have to think too much, just wait for the grenade above to work and force the blood rock creatures out.At first, the blood rock creatures didn't realize what the soldiers and others had thrown in. They looked at each other blankly.

It wasn't until all kinds of grenades began to work that they felt uncomfortable, and more and more uncomfortable.

The most obvious is unable to breathe, and the whole brain is confused, even the surrounding environment can not see clearly.

Even the powerful Lord of blood rock is like this. Although it has strong strength and high resistance, it can't breathe and it can't stand it.

At first, it planned to let the blood rock creatures run to the top of the tower, and the air above might be better.

But it went up to know that the whole tower is this kind of environment, there is no safe place.

This also made Lord Xueyan realize that all this must have something to do with the things thrown in by the road army and others, and he was ready to let his subordinates find these sources and throw them out.

But its orders were given too slowly. Now most of the blood rock creatures are nearly unconscious, let alone finding such a small special grenade.

After searching for some time, Lord Xueyan chose to give up, knowing that it was impossible to complete all this.

At present, there are two options in front of it. One is to choose hard support to endure the duration of smoke and powder.

Because it knows that these things must last for a long time, and it won't last very long, at most ten minutes, and it won't endanger their lives.

The second is to choose to leave the tower and go outside to fight with the soldiers. It's very dangerous, but it's not difficult to be here.

After some thinking, Lord Xueyan decided to hold on and didn't want to go out at all.
