The two mythical beasts returned to the bedroom to rest, although they were full of vitality when they climbed the Great Wall, it was because they had the support they yearned for, and now when they arrived at the courtyard, there was no happiness and food they longed for, so after the spirit was relaxed, they naturally fell asleep.

Yili and Liu Yi were also too tired from playing, so they rested early, and Liu Long was left alone in the entire courtyard except for the intelligent robot bodyguard.

The reason why Liu Long didn't rest was because of the spontaneous combustion accident of the car, to be precise, he was thinking about how to make the flames extinguish instantly.

As we all know, flame combustion requires three major elements, one is combustibles, one is combustibles, and the other is ignition source.

Combustibles refer to substances that can react with oxygen or other oxidizing agents in the air, such as wood, paper, cloth, etc. There are some items in combustibles, which are particularly easy to burn when exposed to open flames, called flammable materials, and the common ones are gasoline, alcohol, liquefied petroleum gas, etc.

Combustibles are substances that can help and support the combustion of combustible substances, that is, substances that can oxidize with combustibles, such as air and oxygen.

The other is the ignition source, which refers to the source of energy for the combustion reaction between combustibles and accelerants. In addition to open flames, physical and chemical factors such as electric sparks, friction, sparks and heat generated by impacts, and heat of oxidation caused by spontaneous combustion can become ignition sources.

Now that you know the three elements of flame burning, if you want to extinguish the flame, you only need to cut off one of the three elements, and then the raging fire will be extinguished, because the three elements of flame are indispensable.

Of course, combustibles are the basis of flame combustion, there can be no flame without combustibles, and when a fire occurs, combustibles are a factor that must exist, so this item can be ruled out, after all, what Liu Long wants to study is fire extinguishing, not combustion.

The remaining two factors, which play a key role in extinguishing fires alone, are combustibles.

And nowadays, all firefighting facilities are based on the factor of combustibles to extinguish fires.

Carbon dioxide fire extinguishers, for example, rely mainly on asphyxiation and partial cooling to extinguish fires.

There are also dry powder fire extinguishers, which mainly extinguish fires through the physical and chemical effects that occur when the powder mist sprayed under the action of pressurized gas comes into contact with and mixes with the flame.

It stands to reason that the current fire protection system is already very perfect, and there is no need for Liu Long to develop fire extinguishers, but in fact, it is not.

According to statistics, the economic losses caused by fires in China are hundreds of millions every year, because the number of fire deaths is as high as four figures, it can be said that if there is a fire extinguisher that can instantly extinguish the flames, then these economic losses and casualties can be completely avoided.

Therefore, if Liu Long can really develop a range fire extinguisher that instantly extinguishes the flames, it is not only the gospel of the people, but also the gospel of the firefighters.

The reason why it is also the gospel of firefighters is because the economic and human losses caused by fires in the whole country just mentioned are the result of the struggle of firefighters on the front line, and this result is exchanged for the lives of firefighters in the nearly triple digits every year, so if there is a fire extinguisher that extinguishes the flame instantly, those firefighters will not bury the fire.

At this moment, Liu Long was thinking, his brain was running at a high speed like a computer.

An hour has passed, Liu Long is still sitting motionless on the sofa, if it weren't for the fact that Dabai could detect Liu Long's life characteristics, I'm afraid they would think that Liu Long had returned to heaven.

Maybe it's because God is also sorry for those who lost their lives because of the fire, so the sky that was originally full of starlight was quietly covered by dark clouds, and then the raindrops fell without hesitation, at this moment, a lightning bolt crossed the sky, followed by a deafening thunder, Liu Long, whose brain was running at high speed, seemed to be frightened under the effect of thunder, and his body trembled slightly and then woke up.

Liu Long glanced at the dark and rainy night sky outside, and then walked quickly towards the study.

Then Liu Long, who was sitting in front of the computer desk, his fingers were in close contact with the keyboard, if there was really a peerless skill of shadowless hands, I am afraid that Liu Long had practiced to the pinnacle of the realm.

"One by one, simulate and model this piece of data. Liu Long, who stopped without a shadow, suddenly said to the computer.

"Okay young master, the data is being simulated, and it is expected to be completed in half an hour. One by one, he did a front flip on the screen and replied.

Since it would take half an hour, Liu Long, who still had some energy, silently opened the door with sesame in his heart, and came to the black technology space.

There is no special change in the space, the main brain still has no reaction, if you have to say that there is a change, it is that the energy spar has become less under Liu Long's daily efforts.

Looking at the four fifths of the energy crystals, Liu Long picked up the space hammer and had a great battle with the energy crystals, and the outcome of the war was not suspenseful, and it still ended with Liu Long being exhausted.

After resting in the space for a while, Liu Long, who was sweating profusely, returned to the real space, and then came to the computer desk after washing up.

"One by one, are the results out?"

"Yes, young master, the simulation results have been completed, and the answer is feasible. One by one, he told Liu Long about the fruits of his labor just now.

After hearing Yiyi's answers, Liu Long couldn't help but shout YES.

According to Liu Long's concept, through the data simulation one by one, the data of the instantaneous fire extinguisher has been completed, and all that remains is to manufacture the first instantaneous fire extinguisher, and then build a production line for mass production.

There are four models of fire extinguishers designed by Liu Long, and they all have a common feature, that is, they can instantly extinguish the fire within three to five seconds after the fire starts.

The first fire extinguisher is a vehicle-mounted instantaneous fire extinguisher designed for spontaneous combustion or combustion of automobiles, his volume is only the size of a lead ball, don't look at his small size, but he can instantly extinguish the fire in a space with a radius of two meters and a height of two meters.

The second fire extinguisher, which is specially designed for families, has the size of a basketball, and his fire extinguishing space is much larger than that of a vehicle-mounted instantaneous fire extinguisher, and he can make a radius of five meters and a height of three meters within the space range from fire.

The third kind of extinguishing firearm, is specially produced for the factory enterprise factory and enterprise type instantaneous fire extinguisher, he has the size of three basketballs, relatively speaking, because of the particularity of the factory and the enterprise, so the scope of this fire extinguisher is still quite wide, in a radius of twenty meters, a height of five meters, he will never allow the appearance of fire.

The fourth fire extinguisher is a forest-level instantaneous fire extinguisher, which is the size of a car, and he can instantly extinguish a fire within a radius of 500 meters and a height of 20 meters.
