Seeing this scene, the viewers in the live broadcast room were also a little surprised.

It's not that they don't believe that the special fire-fighting equipment made by Su Ming can put out fires.

In the live broadcast room, many viewers have been watching Su Ming's live broadcast for a month or two.

I got to know Su Ming a little bit, and I knew that Su Ming never fought unprepared, and that Su Ming was indeed very talented.

However, I believe that the fire rocket produced by Su Ming is useful, but the effect of this thing is also very good!

It's effective, but it's surprisingly good at extinguishing fires, but there's still a gap.

Yao Lie became even more anxious when he saw this scene.

If the effect of this special fire-fighting rocket is so good, and if it can be launched to high-rise buildings, then its effect will be great.

If that was the case, to be honest, he was very excited and wanted to purchase a batch of these special fire-fighting rockets.

This depends on whether the range of rockets can be reached on higher floors, or whether it is beyond reach.

Immediately afterwards, Yao Lie began to arrange a fire-fighting test on the twentieth floor.

This height is already a relatively high floor in the residential area of ​​Longguo.

If it can reach this floor, most residential buildings will catch fire, and this fire-fighting product will be effective.

In other words, as long as the fire-fighting equipment made by Su Ming can reach a height of twenty stories, it will be considered a qualified and useful fire-fighting equipment.

This is also what Su Ming wants to achieve this time.

Fire-fighting tests on the twentieth floor soon began.

The same steps as last time, except this time the fire started at a height of twenty floors.

Regarding this height, Su Ming was not panicked at all, because he designed this "fire" rocket, so he naturally knew that its limit was not that low.

"That's it!" Yao Lie looked at Su Ming with some hope.

On Su Ming's side, a rocket was fired and rushed straight into the abandoned residential floor on the twentieth floor.

Four more rounds were fired immediately, and all of them successfully reached the designated fire location without any deviation.

The fire was the same as the first time, and was successfully controlled quickly. The remaining small flames no longer posed a big threat.

"It's done!" Yao Lie was very excited now.

This fire rocket launcher can reach a height of twenty stories and can already play a key role when a fire actually breaks out.

"Not bad, not bad. The fire-fighting rocket launcher designed by your factory really has very good fire-fighting capabilities. I will report this matter to the superiors."

Su Ming smiled when he heard this, knowing that it was done.

As long as Yao Lie and the others approve this special fire-fighting equipment, then according to what Lu Tianheng said, their factory can produce this kind of fire-fighting equipment in Longguo.

"Should we continue testing next? After all, we still don't know the ultimate fire-extinguishing height of your fire-fighting rocket?!" Yao Lie asked.

Yao Lie is now more and more interested in the "bazooka" in Su Ming's hand. In their opinion, this rocket launcher is enough to be used as a qualified fire-fighting product. However, Yao Lie still has no idea how high the maximum range of the "bazooka" is. Got it.

If this test is not continued, Yao Lie will be too depressed to sleep tonight.

At this time, Su Ming also wanted to know what the maximum altitude range of the rocket launcher was.

Because when Su Ming designed this rocket launcher, it was mainly for export to Heizhou.

Therefore, Su Ming has a clear understanding of the conventional usage of rocket launchers, direct shooting or low-angle projectile distance. The effective range of this rocket can reach 600 meters.

In other words, for direct shots or low-angle shots within 600 meters, the accuracy is very accurate when the influence of gravity is small.

But if the effective range exceeds 600 meters, the maximum range is one kilometer, but the accuracy of the rocket launcher will decrease.

In a situation like this where the elevation angle is relatively large when launching from the ground to a high-rise building, the rocket is greatly affected by gravity.

Both the ultimate range and the effective range will be greatly affected. Su Ming did not make a clear calculation, but according to Su Ming's conservative estimate, the height of a thirty-story building, which is about one hundred meters, is at least achievable.

Yao Lie was very happy to see that Su Ming agreed to his idea of ​​continuing the test.

"The height of the 20th floor is already considered a high-rise. How about we test the height of the 25th floor next?" At this time, Yao Lie chose to ask Su Ming for his opinion.

But Su Ming shook his head: "Just go up to the 30th floor, I think it should be fine."

The reason why he went directly to the 30th floor was that Su Ming had the confidence and didn't want to waste time.

On the other hand, Su Ming brought a total of twenty-five rounds of special fire-fighting rocket ammunition this time. There was not much ammunition to begin with, and ten rounds had already been used.

It’s better to save some money, just in case you don’t have enough later!

"Okay, I'll do as you say."

Ten minutes later, a raging fire broke out on the 30th floor of the abandoned building.

However, it was quickly extinguished by five specially-made fire rockets, and the accuracy was still 100%.

Yao Lie was overjoyed when he heard the results from upstairs.

This result has greatly exceeded his expectations.

You must know that today's urban communities are generally up to thirty stories high.

At this height, the fire rocket launcher can still work. It can be said that it can work in almost all residential buildings.

At this time, Yao Lie was really moved. If their fire brigade could have this kind of equipment, it might be possible to save a life or reduce people's property losses at critical moments.

"I don't know when this thing will be officially produced. If it is officially produced, our fire brigade will have to apply for funds to purchase several such fire rocket launchers." Yao Lie thought this way.

Next, he tried Su Ming's fire bazooka at a height of thirty-five floors.

Of the five shots fired in this test, three hit the target and two missed the ignition point. They either shot high or low.

Obviously at this height, the accuracy is no longer good.

But it cannot be said that it has no effect. The lack of precision can be completely filled with quantity.

There is no need to try again at higher altitudes.

But Su Ming was very satisfied with the result.

Also very satisfied is Yao Lie.

Looking at the "fire bazooka" in Su Ming's hand, his eyes were filled with longing.

After completing the fire extinguishing work, other firefighters on standby gathered around.

"Captain, when can we equip this!"

"Yes, with this thing, we no longer have to worry about the fire truck being blocked outside the community and unable to enter."

"..."

Although all the firefighters present said they were talking to Yao Lie, their eyes were just like Yao Lie's, staring at the "bazooka" in Su Ming's hand.

At this time, the test of the special fire-fighting equipment produced by Su Ming's factory was completed. Logically speaking, there was nothing else to do. Yao Lie should send Su Ming and the others to leave the training ground as soon as possible.

But at this time, Yao Lie had no intention of letting Su Ming and the others leave.

"Director Su, when will your firefighting equipment be available for sale?" Yao Lie asked.

Hearing this, Su Ming was stunned. What do you mean? Yao Lie wanted to purchase this product.

But Su Ming thought for a while and said, "It must take half a month anyway!"

Although Su Ming said it would be half a month, Su Ming knew that the first batch of orders must be for Heizhou. After all, it was an urgent situation there.

But if Yao Lie and the others want less, Su Ming can leave a few for them, which is not a big problem.

However, according to Su Ming's prediction, the order volume of this kind of fire-fighting rocket launcher in the domestic market will have to wait for some time to slowly develop. Only after it has gained a reputation can the order volume be increased.

There was no need to rush, and for now, the production capacity of Su Ming's factory could not keep up with so many orders.

"There's still half a month left. This is very fast!" Yao Lie was very surprised.

However, although half a month is not a long time, Yao Lie does not want to wait that long, after all, it is already ready-made!

After hesitating for a moment, Yao Lie couldn't help but said: "Director Su, we also like this fire bazooka very much."

"We also have the intention to purchase a batch, but before that, can you let us try it for a period of time to see the effect? ​​If the effect is good, we will definitely purchase it."

"Of course, we will pay as usual for this trial."
