"Indeed, the internal environment of the tower is very suitable for implementing this plan. As long as we throw grenade from the top level and make these monsters nowhere to go, they will definitely come out."

"My only concern is that these grenades may not have an effect on the blood rock clan, after all, they are creatures from other planes."

"And how we defend after they come out is also a problem. Too many creatures rush out at once, and we may not be able to defend." Ruan Bing's tone next to him was filled with strong concern. It seems that she has taken all the points that are easily overlooked. Considered.

"Well, what you said is very reasonable, and I agree very much, so we have to try it anyway, and the sooner the better." Lu Jun nodded, "As for the defensive method, don't worry too much about this. Let me talk about it."

In fact, Lu Jun is not very afraid of all the blood rock creatures coming out, because he still has a large number of dinosaurs.

The more enemies, the better his dinosaurs will perform, so the Lu Army is not worried at all now.

While talking about the road army, he took out a large number of special grenade bags from the armed module and threw them into the hands of Ruan Bing and Xiaowan: “I’m not enough alone, and you come together. We try to make this tower within one minute. It's all smoke and poisonous gas."

"In addition, you also have to prepare Lin Yilan and Ruan Xue to withstand the impact. The battlefield may be chaotic later."

"understand."

"understood".

Xiao Wan and Ruan Bing nodded one after another, and had no objection to the Lu Army's order.

Seeing that everything was ready to be completed, the Lu Army took the lead to spread the dragon wings and flew to the top of the tower, while Ruan Bing and Xiao Wan dispersed in different directions.

As time passed about ten seconds, the Lu Army smoothly reached the top of the tower. Before he even thought about it, he threw a green grenade and a white grenade into it.

The full names of these two gadgets are Misty and Toxic, and the effect is to spray powder and release highly poisonous.

The powder is used to prevent any creature from breathing. If you breathe in this kind of thing, it will be uncomfortable, sneezing and sneezing.

The highly toxic effect is to inhibit the nervous system of any creature, make them hallucinate, and lose the ability to judge.

Anyway, the diffusion of these two grenade is very strong, enough to achieve the effect that Lu Army thought.

When the two special grenade entered the top of the tower, the inside immediately became blurred, and nothing could be seen clearly.

At the same time, there is powder and smoke, which makes people feel sick when they are far away.

Seeing that the entire top floor was sealed off, the Lu Army was very satisfied, and flew to the next floor, repeating the actions just now.

Xiao Wan and Ruan Bing also arrived under the tower at this time, taking care of the floors that needed them.

Although inside the tower are blood rock creatures holding weapons, it looks dangerous.

But in fact, Lu Jun and others don't need to go in, just use the small mouth opened by the tower to throw all kinds of grenades in, even if there are more blood rock creatures, they can't help them.

The leader of the blood rock in the tower also knew that the Lu Army and others were around the tower, but he didn't know what these humans were doing...

A few minutes later, basically the entire floor of the tower was filled with dust and green smoke, which also meant that the initial goal of the Lu Army and others had been achieved.

Especially on the floors where the blood rock creatures and the blood rock lord are located, they threw three times as many grenades.

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

Now they don't need to think too much, just wait for the grenades above to show their effect and force the blood rock creatures out.

At first, the blood rock creatures didn't realize what Lu Jun and the others threw in, and looked blank.

It wasn't until the various grenades started to work that they felt uncomfortable, and they became more and more uncomfortable.

The most obvious is that he can't breathe, and his entire head is dumbfounded, and he can't even see the surrounding environment.

This is true even for the mighty Blood Rock Lord, although it has strong strength and high resistance, it can't breathe and can't stand it.

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

But after it went up, it realized that the entire tower was in this environment, and there was no safe place anymore.

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

But its orders were too slow, and now most of the blood rock creatures are close to losing consciousness, let alone finding such a small special grenade.

After searching for it, Lord Blood Rock chose to give up, knowing that it was impossible to accomplish all this.

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

Because it knows that these things must have a duration, and will not be very long, at most ten minutes, and will not endanger their lives.

The second is to choose to leave the tower and go outside to fight with the Lu Army and others. This is very dangerous, but it will not be aggrieved here.

After some thoughts, Lord Blood Rock decided to hold on and didn't want to go out at all.

The reason for this idea is that the actions of the Lu Army and others are too obvious, they are forcing them to go out for a decisive battle.

Although Lord Bloodstone is not extremely clever, this little Ni Duan is still easy to see.

Since the Lu Jun and others thought so, it just didn't do so, so that the Lu Jun and others could not achieve their goal.

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

If you can't stand it anymore, stretch your head to the window and take a breath. The air over there is still okay.

Anyway, as long as they withstand the pressure and last these ten minutes, Lu Jun and others are absolutely helpless.

At that time their reinforcements will also come from afar, and then it will be their turn to fight back, the Lord Bloodrock thought viciously.

After receiving the order from the Lord Blood Rock, the blood rock creatures in a daze can only choose to obey.

It is impossible for them to fight now, they can only live in a place with less dust and smoke.

Seeing that no blood rock creatures came out at the entrance and exit of the tower, Lu Jun, Xiao Wan and others frowned deeply.

Because this meant that their plan had failed, the Lord Blood Rock did not come out, and they could not implement the next step.

"How is it possible? Are those grenades that have no effect on the creatures on this plane? It hasn't come down for so long, shouldn't..." Lu Jun muttered with a distressed expression, his eyes never leaving the tower.
