Sure enough, just as Liu Long and Yili were discussing the demise of the Black Killer Organization, the doorbell at the gate of the courtyard was ringed.

Through one by one, I learned that it was none other than Zhan Ming, who I hadn't seen for a long time.

Liu Long came to the imperial capital several times, but he didn't see any trace of Zhan Ming, could it be that he was transferred to another department, in fact, it was not.

The reason why the elder's secretary contacted Liu Long several times in person, instead of Zhan Ming, it turned out that he was sent to carry out a secret mission, it stands to reason that this task is not his scope of responsibility, but he is the most suitable person, so after special approval, he had to be "borrowed" away, in fact, this secret mission is also inextricably linked with Liu Long, that is, the artificial intelligence source code leak of the Academy of Sciences some time ago.

It wasn't until yesterday that this secret mission of his work was completed, so he took up his old job, the liaison officer between space science and technology and the country.

"Chairman Liu, I haven't seen you for a long time, I miss it very much. Zhan Ming, who was already an old acquaintance, came to the living room and said to Liu Long.

"I said how come there are magpies flying in front of the house today, it turns out that there are distinguished guests coming, welcome to occupy a place to come to the cold house, please sit. Liu Long replied politely.

"Liu Dong, this time I came here on official business, so I won't sit down, if it is convenient for Liu Dong, please go with me to the relevant departments. Zhan Ming directly stated the purpose of this arrival.

"Why, is this because the relevant departments see that I have made great contributions to the country recently, and they want to promote me to a military rank. ”

Liu Long knew that the reason why Zhan Minglai came was because some people did not want to contradict Liu Long, after all, the people in the relevant departments all served the country, and it would not be an exaggeration to say that they had no tendons, and it could also be said that they were some extreme patriots, they never participated in any gang fights in the country, and their purpose was to serve the country only in everything.

"Also, Liu Dong's military rank should also be promoted, after all, he has made such a huge contribution to the country recently, after I go back, I will immediately apply for it like the relevant department, but you see if you want to go with me." At this time, Zhan Ming did not have the momentum of the director, but said very calmly, after all, he also knew that Liu Long ate soft and not hard.

Liu Long left and followed Zhan Ming, but it didn't take long for him to come back again, no one knew what he had experienced in the relevant departments, but it was not difficult to see that Liu Long was in a very beautiful mood after coming back.

"Husband, did they embarrass you? Seeing that Liu Long returned to the courtyard unscathed, Yili asked with concern.

"Don't worry, don't look at who your husband is, what can happen. Liu Long hugged Yili and said to Yili in a gentle tone.

Just when they were showing their affection, the phone rang again.

After receiving a big roll of the eyes from Yili, Liu Long picked up the phone.

"Young master, the instantaneous fire extinguisher production line has been built, and the first batch of instantaneous fire extinguishers is about to roll off the assembly line, does the young master need to personally test their performance?" Liu Luo on the other end of the phone reported to Liu Long.

Liu Long didn't expect that the instantaneous fire extinguisher would enter mass production so quickly, so Liu Long led a large and two small ones to get on the flying car to the space machinery on the grounds that he had never been to the space machinery as the proprietress had never been to the space machinery.

I have to say that with a flying car, it is more convenient than an airplane, and it didn't take long to reach the destination.

Under the greeting of Liu Neng, Liu Luo and others, Liu Long Yili and the two divine beasts walked down from the flying car.

After introducing each other, Yili and the Divine Beast went to visit the factory, while Liu Long came to the experimental site that had been arranged.

After taking over the vehicle-mounted instantaneous fire extinguisher from Liu Luo, Liu Long first tested the intelligent detection and automatic fire extinguishing function of the instantaneous fire extinguisher, put the instantaneous fire extinguisher on the edge of the fire point, and then poured gasoline on a scrapped car.

After detecting the source of the fire, the instantaneous fire extinguisher was activated instantly, only to see that the fire that was still billowing in smoke and soaring into the sky just now was extinguished in an instant. And the billowing smoke and dust also disappeared at the same time, and about 5 seconds later, only the sound of the instantaneous fire extinguisher was heard: the fire is merciless, and it is cherished.

Liu Long knew that all the steps of extinguishing the fire had been completed, walked to the fire point, picked up the fire extinguisher and observed, and then continued to experiment with other fire sources and the fire extinguishing effect of the fire extinguisher.

For the effect of various types of instantaneous fire extinguishers, Liu Long is very satisfied.

At this time, Yili and the two divine beasts who followed the intelligent robot to the factory walked to Liu Long's side.

"Husband, what is this. Yili asked curiously when he saw something similar to a lead ball in Liu Long's hand.

"This is our company's new product, the instantaneous fire extinguisher, this time back, not only to lead you to visit the factory, he is the main purpose. After Liu Long finished speaking, he also raised the vehicle-mounted instant fire extinguisher in his hand.

"Can you really extinguish the fire in an instant? After hearing Liu Long's words, Yili became interested.

"Of course. ”

"But he's so small, how can he be a fire extinguisher? Erie was skeptical.

"Why is this not a fire extinguisher, and you missed a word, it is an instantaneous fire extinguisher, and his extinguishing range is eight cubic meters, that is, a space with a radius of two meters and a height of two meters, and his extinguishing time only takes at least two seconds. ”

"How is this possible, such a large space, the fire extinguisher is still so small, and the time to extinguish the fire is so short. Yili put the instant fire extinguisher in front of his eyes again, and looked at it carefully for a while, but he still didn't see the reason.

"If you don't believe it, you can experiment it yourself. ”

After Yili tested the instantaneous fire extinguisher, he was stunned by his performance.

"Husband, this is true, and it can automatically detect, automatically extinguish fires, and most importantly, filter dust and purify the air. Yili, who woke up from his surprise, said excitedly to Liu Long.

This cannot be blamed for Yili's short hair and short vision, the main thing is that it is completely beyond the scope of understanding.

Invented in 1816 by British captain Manby, a Norfolk native, the first real special-purpose fire extinguisher consisted of just one or two drums filled with more than one litre of water and compressed air. With the progress of the times, there are more and more types of fire extinguishers, which can be divided into: portable type and cart type according to their moving mode; according to the power source of driving fire extinguishing agent, they can be divided into: gas cylinder type, pressure storage type, chemical reaction type; according to the filled fire extinguishing agent, it can be divided into: foam, dry powder, halide alkane, carbon dioxide, acid and alkali, clean water, etc.

There are so many kinds of fire extinguishers, and none of them dare to say that they can extinguish the fire instantly, as well as his volume and the scope of the fire extinguishing, the most important thing is that he can filter dust and purify the air, which is a proper black technology.
