Happy New Year.

The mining school was built at the foot of a small hill called Fengming Mountain at the northern foot of the Qinling Mountains, with the copper mine on the left and the Fengming River on the right. Beautiful and pleasant scenery.

The mining school adopts a part-time teaching method, so the students must participate in the process of building the school and the process of building the mine.

The institute financed and hired some of the local people, who worked all day, and the students participated in the labor in the afternoon.

Fengming Mountain is 19 miles away from the county seat of Xu, and the official road from Yongzhou to Hezhou passes through the mining area, and the mining school should build a 3-mile long road to connect with the official road.

On this day, Li You came to the construction site, accompanied by Yu Chi Baoqi and others, to check the road construction.

The roads of the Tang Dynasty were mainly built of rammed earth, and the most feared of this kind of road was the rainy season, which was easy to break and often muddy.

Li You felt that it was time to develop cement, and he said to Zhao Fu, the supervisor of the infrastructure construction office: "This kind of road is really not good, and a waterproof hard pavement should be added to the rammed earth pavement." ”

As he spoke, he introduced the relevant knowledge of cement.

For the magic of the prince, everyone has long been accustomed to it. Zhao Fu said: "Lord Wang, the little one will take someone to burn this cement immediately." ”

Li You said that he was not in a hurry, and asked him to transfer some craftsmen and some students, and he wanted to give them lessons.

He then talked about how to use the abundant water resources here to crush stone and drive conveyor belts.

At this moment, the white tiger pointed in the direction of the official road and said, "Lord Wang, a messenger is coming." ”

The person who came was sent by Zhongshu Province to pass the decree, and he said, "Please ask His Royal Highness the King of Qi to accept the decree." ”

After receiving the order, Li You said: "I won't go back to Chang'an, isn't my father just going to solve the plague, I'll write a note, you can take it back." ”

Qin Cha was a little embarrassed and said, "Your Highness, Your Majesty's will is for you to return to Chang'an, this ...... All right? ”

Li You said with a smile: "Go back, that is to say, these few words, you can rest assured, my father will not blame." ”

"Okay, the minister will report it truthfully, Your Highness is not strange." The messenger said.

Li You wrote the recital, handed it to Qincha, and then continued to popularize science for Yu Chi Baoqi and others.

As Li You said, Li Shimin just wanted to get a way to solve the plague, and when he saw Li You's recital, he didn't say anything.

The next morning, Taiji Hall.

Soon after the start of the early dynasty, Li Shimin said directly: "Ladies and gentlemen, there is a solution to the plague, and the prince and Fang Xuanling must implement it as soon as possible." ”

Li Chengqian and Fang Xuanling responded to the order.

There was a burst of discussion in the main hall, and everyone was very curious about how Li You solved such a complex problem.

Xiao Qian said: "Your Majesty, what is the idea of His Royal Highness King Qi, the old minister is very curious, can you say something?" ”

"Yes, Your Majesty, the ministers are also curious." The ministers echoed for a while.

Li Shimin smiled: "This kid really has him." Ha ha. Liu Quanzhong, you can tell everyone about it. ”

Liu Quanzhong said: "His Royal Highness King Qi said that on the basis of the measures that have been taken before, strengthen preventive measures. Medicines are distributed in urban areas and other places according to household registration. This solves the problem of preventing and controlling the plague for most people.

The difficulty lies in the floating population, such as merchants, porters, beggars, and other migrants.

His Royal Highness King Qi's opinion is that cards should be set up at all major intersections to register and distribute medicines to those who have not received them. This solves the problem of some people.

The rest of the people, scattered all over the place, because they don't have a local household registration, or if they can't be notified for some reason, such as beggars, they always need to drink water. His Royal Highness King Qi said that by putting medicine in public wells everywhere, basically everyone's problems would be solved. ”

"Ah, put medicine in the well, I see. Such a simple solution, why didn't I think of it. ”

"It's not an easy solution, and it's not easy to come up with such a solution."

There was a burst of chatter.

Li Shimin said: "Ladies and gentlemen, Li You, the king of Qi, is willing to use his brains, and this point must be vigorously promoted." ”

The eldest grandson Wuji gave Li Chengqian a look, and Li Chengqian came out and said: "Father, Li You, the king of Qi, has repeatedly solved problems for the imperial court and made many great contributions. The imperial court should give a reward.

Erchen suggested that Li You be promoted to a first-class prince. ”

The eldest grandson Wuji immediately said: "The minister agrees with His Royal Highness the Crown Prince's opinion. The minister seconded. ”

Yin Hongji didn't expect them to have such a proposal, and was a little surprised. However, he was very happy and immediately said, "The minister seconded the proposal." ”

Xiao Qian, Wei Zheng, Fang Xuanling, Hou Junji, Li Daozong, Cheng Yanjin, Wei Chigong and others all came out to second.

The prince's subordinates, who had been notified in advance, seconded the proposal.

Most of the ministers came out and seconded the proposal.

Li Ke was grateful to Li You for saving his life and also came out to second.

Although Li Tai was a little reluctant, seeing that the general trend was like this, the opposition was also invalid, so he simply came out to second.

Everyone in the hall came out to second.

"Good, good. The prince's proposal is very good, and it is exactly what I want. I have made up my mind, promoted Li You, the king of Qi, to a first-class prince, and gave 1,000 households and 3,000 acres of fiefdom. Chin this. ”

Yin Hongzhi was very excited, as soon as the early dynasty was dispersed, he asked to go to see Concubine Yin, and at the same time sent someone to inform Yin Guanghao and asked him to send someone to Li You to send a letter.

Qi Wangfu.

King Qi's promotion is a great news for the whole Qi Palace. The status of the King of Qi has improved, and the tide has risen, and the status of the people in the Qi Palace's Mansion has naturally improved.

Since the prince suddenly forked, the people of the Qi Wangfu walked on the street and raised their chests one by one, and they almost wrote "I am from the Qi Wangfu" on their faces.

Qi Wang Niu Cha doesn't say, there is still money, the key is to be generous. The benefits of the Qi Palace's Mansion are incomparable to anyone's. That alone is enough to be enviable.

Now, the prince is even more bullish, after he comes back, a large amount of happy money is certain, and everyone is looking forward to the prince coming back quickly.

After Tian Min got the news, he immediately arranged to celebrate.

The others in the palace asked, "Lord Changshi, the prince is not in Chang'an, do you want to wait for him to come back and celebrate?" ”

Tian Min said: "If there is something good to celebrate in time, it must be done immediately, so that the neighbors can see the majesty of our Highness."

Your Highness is back, so why don't we celebrate it again? The order went down and a feast was held at noon. ”

The crowd was overjoyed and hurried out to set it up.

Not long after, in front of the gate of the Qi Palace, there was the sound of bursting rods and the noise of gongs and drums.

The noise of the Qi Wangfu spread to the Shu Wangfu not far away, and everyone was envious one by one.

On the wall of the Shu Palace, Quan Wanji's face was cloudy, and he didn't know what he was thinking.
