Li You then explained other firefighting equipment: firefighting ladders, firefighting axes, firefighting goggles, firefighting uniforms, firefighters' ordinary protective clothing, etc.

Subsequently, he handed over the task of developing fire-fighting equipment to the research institute and asked the Ministry of Industry to cooperate.

The research institute judged that Huang Suxin had a lot of experience in organizing and developing the work, and when Li You explained the fire-fighting equipment, he was already thinking about how to organize and develop the fire-fighting equipment.

He said: "Your Highness, the minister has roughly calculated that about 230 craftsmen of all kinds are needed, and the institute currently has more than 70 craftsmen, and it also needs strong support from the Ministry of Industry. ”

According to the Ministry of Works, he is responsible for the allocation of craftsmen no matter how many craftsmen are needed.

Seeing that the task was assigned, Li You announced the adjournment of the meeting, he took the lead in leaving the conference hall, and everyone also walked out one after another.

Suddenly, Li You saw a servant in the courtyard fetching water from the well, and the servant was using a hand-cranked wheel to draw water, he first threw the bucket into the well, shook the rope to let the bucket fill the bucket, and then shook the roller to lift the bucket.

The wells of the ancient people did not have manhole covers, and a pavilion was built on them and a hand-cranked Lulu was installed if possible. Wells without conditions are open-air, unhygienic and unsafe.

The ancients, especially women, chose the most common method when committing suicide by throwing themselves into a well. The main reason is that there is no manhole cover, so it is convenient to throw into the well.

Once this happens, the well water is basically no longer willing to drink, and the well is scrapped.

He said, "Wait a minute, don't go yet." ”

With that, he reflexively returned to the council chamber, and everyone followed, sitting back where they had just been.

Li You walked to the blackboard and drew a simple diagram of a manual water pump, he said: "This picture is a water pressure pump, and this device is simpler to make than a high-pressure water pump.

Installing such a pressurized water pump on the wellhead makes it much more convenient to use water. And the wellhead can be equipped with a lid, which solves the safety and hygiene problems. ”

Huang Furui said excitedly: "Your Highness, this method is good, this is a great act of kindness for the benefit of the people of the whole world." Leave this matter to the minister, the Ministry of Industry will definitely be able to make such a thing soon. ”

Huang Furui was very concerned about the production of pressurized water pumps, and after he went back, he organized people to develop them, and it didn't take long for two to be produced. After the craftsmen reported it to him, he couldn't wait to experiment with it himself.

On this day, Huang Furui took several craftsmen, holding the pressurized water pump they developed, and came to the Qi Wangfu in a hurry.

"Your Highness, look at it, what a good thing!" He held a pressurized water pump in his own hand and let Li You watch.

Li You smiled: "Okay, that's what it looks like." Next, it is necessary to organize mass production, which is a very large industry. ”

Huang Furui said: "Your Highness, the minister has always been a strong supporter of you, can you think of the minister for good things?" ”

Li You knew what he wanted, and said with a smile: "Well, this pressurized water pump will be produced by your Ministry of Industry." ”

Huang Furui was overjoyed, and arched his hand and said, "Then thank you, Your Highness." The minister understands that the patent fee in this is guaranteed to be sent to the Qi Palace. ”

Li You smiled: "Then I will thank Master Shangshu." Ha ha. ”

Soon after, the Ministry of Industry set up a large-scale processing plant, and in order to promote this product, they carried out public experiments in public wells on the streets of Chang'an, and won the love of the majority of Chang'an citizens.

Li You also published a signed article in the "Datang Daily" with this title, entitled "Gewu Changes Life".

Gewu is a very broad concept, but in the eyes of most people in ancient times, it specifically refers to the skill of winning odds, that is, invention and creation. Over the years, under the vigorous promotion of Li You, people's concepts have gradually begun to change.

Li You used the example of the convenience brought by the pressurized water pump to people's lives, illustrated the importance of invention and creation to improve people's lives, and he encouraged people to devote themselves to the ranks of invention and creation.

Li Chengqian also attached great importance to this matter, and he also published a signed article to support Li You's viewpoint.

Qi Wangfu.

On this day, the general Li Jing sent someone to send a battle report, saying that Li Shimin was angry that he did not take the city of Anshi last year, and this time he was determined to take the city with his own hands.

After last year's war, the Goguryeo people are well aware of the importance of Anseongseong. After the last retreat of the Don army, they reinforced the already strong city walls. Now that winter is on, they are pouring water and ice on the walls, which makes the siege even more difficult.

So far, the Don Army has organized a number of large-scale offensives, and still no progress has been made.

Li Shimin was angry and urged the Tang army to strengthen the siege. As a result, the Don army suffered heavy casualties. Li Jing and others persuaded him many times, but they could not change Li Shimin's determination.

Li Jing thought of Li You and sent people to Baekje to look for Li You, and the messenger heard that Li You had returned to Chang'an, so he found this place.

In order to let Li You figure out the situation on the front line, Li Jing introduced the siege tactics adopted by the Tang army to Li You one by one.

The tactics adopted by the Tang army included frontal assault, feint attack, night attack, persuasion to surrender, digging tunnels, etc., among which the Tang army also used fierce fire oil.

However, due to the limited distance of the trebuchet, the Goguryeo people had already moved the inhabitants around the city walls to the middle part of the city. Although the Tang army caused many fires to the Goguryeo people, it was not able to inflict significant losses on the Goguryeo people.

Seeing this, Li You was helpless for a while, and he said to the messenger: "You stay in the mansion first and have a good rest." I'll figure it out as soon as I can. ”

Li You rarely has insomnia, but last night because he was thinking about the affairs of Anshi City, he didn't fall asleep until 5 o'clock in the morning.

Early the next morning, the habit of getting up early formed over the past ten years, the biological clock woke up Li You on time. He was really sleepy, but he didn't want to disrupt his habits. He gritted his teeth and got out of bed.

On an early winter morning, there was already a bitter chill in the air. Li You came to the garden, and after warming up, he practiced swordsmanship with the white tiger.

In the process of sparring, Li You was a little inattentive and was almost injured by the white tiger's wooden sword.

Baihu hurriedly stopped and asked, "Lord Wang, you don't look very good, didn't you rest well last night?" ”

Li You didn't have the heart to practice the sword anymore, and said, "Yes, I thought about things last night and didn't sleep well." You go and inform them that breakfast is a little earlier, and I want to sleep a little more after eating. ”

"Okay, let's go for the little one." The white tiger walked away quickly.

Li You yawned as he walked towards the dormitory.

After breakfast, Li You instructed Baihu: "I'll sleep for a while and wake me up on time at 10 o'clock." ”

Li You entered the dormitory, and as soon as he lay down on the bed, he heard someone talking in a whisper outside.

"Your Highness, the prince has just rested, what do you think about this matter?" It was the White Tiger who spoke.

"I'll go and get him up." It was Xiao Wanyu's voice.

Li You knew that there must be something urgent, so he simply sat up.

He said, "Wanyu, come in." ”

After Xiao Wanyu came in, she said apologetically: "Brother You, I really want you to have a good rest, but I really can't help it." ”

Li You asked, "What's wrong?" ”
