"Lord Wang, you're here."

His Royal Highness King Qi is different from other princes, he is the one who comes to the kitchen the most, and the cooks are very familiar with him.

Li You said: "Wang Liao, you go and get some charcoal, mash it, and then take a flower pot with holes in the bottom, wash it, and fill it with this broken charcoal."

Take a few catties of coarse salt from pickled vegetables and turn them into water. Bring me some more linen and silk. ”

Wang Liao didn't ask why, and directly ordered his subordinates to do it.

It didn't take long, and it was all ready.

Li You asked Wang Liao to strain the dissolved brine with several layers of linen and silk, and then pour it into a flower pot filled with charcoal crumbles, and then put a copper basin underneath, and then filter out the brine water.

These brines are then filtered several times.

Charcoal is not activated carbon, and the adsorption function is poor, so Li You has to filter it many times. When the filtered brine looked clear, Li You said, "Put the brine in the pot and boil it dry." ”

In the summer, there was an open fire in the kitchen, and it was a little stuffy, Li You ate an ice cream and said: "You work in the kitchen every day, it is very hard, from today onwards, the monthly salary will be increased by 20%. ”

The chefs cheered.

The prince is a foodie, and the closest relationship with foodies is, of course, the chefs. Need is value, and the chefs of the Qi Wangfu are the highest status in the entire chef world.

In the past half a year, the monthly income has risen several times.

The brine finally boiled dry, leaving a layer of salt particles at the bottom of the pot. Wang Liao and the others scraped off the salt and put it on a plate.

Li You pinched up a few grains of salt, put them in his hand and looked at them, and then put them in his mouth.

"Well, yes, that's it."

He said to the cooks, "Come, take a look, taste it." ”

"Oh, lord, this salt, this salt is so good, it's better than the fine salt we use." Wang Liao said excitedly.

"yes, yes." The chefs were excited.

Li You smiled: "This is the salt that people eat." ”

……

The next morning, Li You took the agreement signed with Murong Ling and went to see Li Shimin.

Li You entered the imperial city, and not long after walking, he saw Gao Jingming talking to two officials at the front door.

Gao Jingming saw Li You, sent the two officials away, and greeted him.

"Your Highness." Gao Jingming beckoned.

"Tall, sir." Li You returned the salute and said.

Gao Jingming said with excitement on his face: "Your Highness, I heard that there is a salt lake in Tuguhun, which can make salt, when will it increase the income of the household, and how much?" ”

Li You said: "I was about to go to see my father, and this is what I said, you can go with me." ”

Liangyi Palace, study.

Li You took out a small cloth bag from his pocket, picked up a piece of rice paper and spread it on the table, and poured the salt in the bag on it.

He said, "Father, my lords, this is refined salt. ”

After everyone tasted it, they were amazed.

Gao Jingming asked: "Your Highness, this salt is better than the salt we usually eat, how is it made, and is the cost high?" ”

Li You said: "Whether it is sea salt, lake salt, well rock or rock salt, they all contain impurities, so they are a little bitter. However, these impurities can be filtered out.

There is a kind of charcoal called activated carbon, which is different from ordinary charcoal, which is made of charcoal at high temperature and using a certain processing technology, and the raw materials are coal, bamboo charcoal, charcoal, walnut shells and coconut shells. Among them, walnut shell and coconut shell have the best effect......"

Li You popularized the relevant knowledge, and then said: "Father, whether it is sea salt, lake salt, well rock or rock salt, the sons have ways to improve the yield and quality, and Datang will never be bothered by the problem of salt in the future." ”

The scarcity of salt has been the norm in all dynasties, so the imperial court will implement the monopoly of the salt industry.

The income from the salt industry accounted for a large proportion of the imperial court's tax revenue. For example, after the Anshi Rebellion, the imperial court raised the price of salt from 11 to 110 wen per bucket, a tenfold increase in price, and the income from salt accounted for seventy percent of the total financial revenue of the imperial court.

Li Shimin was overjoyed, he was determined to be the first emperor of the ages, and the country was not short of salt, which was an unprecedented grand achievement.

Li You suggested that in the future, the imperial court should re-plan the production, sales, transportation and storage of salt, and the important ministers should be responsible.

When Li Shimin asked Li You to preside over the matter, Li You recommended the crown prince Li Chengqian, which was approved by Li Shimin.

The eldest grandson, Wuji, cast a grateful glance at Li You.

In the end, Li You took out the draft agreement signed with Murong Ling.

For Datang to account for seventy percent of the Tuyuhun salt industry, everyone is very satisfied.

Li You said: "Father, son-in-law suggested, in the name of protecting salt, I, the Tang Dynasty, sent an army into Tuyuhun, and when the Tubo people retreated, the army drove directly into the salt lake to carry out tuntian, uh, tunyan."

In this way, it is possible to station a large army in Tuyuhun in a dignified manner, develop the lake salt, and at the same time control the situation in Tuyuhun.

In the future, when the time is ripe, it will annex Tuyuhun in one fell swoop. ”

The ancients paid attention to the name of sending troops, and Fang Xuanling agreed: "Your Majesty, the minister thinks it is so safe. ”

The Tang Dynasty is a tiger, Li Shimin is very keen on expanding the territory, and the ministers are not good at it.

Li Shimin praised: "The people take food as the sky. This diet is really a university question, and it can solve a lot of problems. ”

……

Li Tai has been very busy lately, and Zhang Luo is preparing for the test questions.

Each of Li Tai's test questions is not simple, and it costs Li Shimin a lot of money, but these questions are luxurious and interesting, and Li Shimin doesn't care about money.

Honglu Temple Guest House.

Lu Dongzan led the Tibetan delegation to Chang'an, which was to achieve the goal of marrying with the Tang Dynasty, and then sign a peace agreement with the Tang Dynasty, so that the Tang Dynasty could not tear up the peace agreement and interfere with their plan to annex Tuyuhun.

Since the two countries did not have much contact with each other and were not very familiar with each other, especially the Tang Dynasty, one of the purposes of the mission was to declare the strength and development of Tibet, so that the Tang Dynasty would have some scruples.

The Tang Dynasty was a great country, and the Tubo people were far more familiar with the Tang Dynasty than the Tang Dynasty was familiar with the Tubo, and the Tang Dynasty people generally believed that the Tubo people were barbaric and backward, and they were very contemptuous.

The Tang Dynasty adopted the method of testing, which was in the hands of the Tubo people. Lu Dongzan wanted to show his talent, so that the Tang Dynasty people would not dare to underestimate them and the Tubo people.

Lu Dongzan is a super examiner, and all exams from childhood to adulthood are based on one. He is not only smart and studious, but also has developed a good habit of being good at thinking.

Li Tai was not idle, and Lu Dongzan was not idle, he did everything possible to find out the news about the test.

On this day, a Tibetan merchant said: "My lord, I have inquired about the whereabouts of Her Royal Highness the princess's nurse brother and gave him a large sum of money, and I have written down the physical characteristics of Her Royal Highness the princess." ”

As he spoke, he handed Lu Dongzan a piece of paper full of words.

Lu Dongzan praised him and rewarded him with a lot of money.

Soon, Lu Dongzan received news that there were many horses near the Imperial Garden, and there were many carriages pulling logs.

Qi Wangfu.

Li You was not idle, he was busy studying how to set up a trap to pit Lu Dongzan.
