Wang Qiang soon entered the role of the hostess, and on the third day after the wedding, she called Zhang Shu, the head of Jinyang Palace, and said that she wanted to see the gift list.

It's just that after taking the account book, he was dumbfounded.

"What is this?" She asked, pointing to the symbol on it.

"Hui Yu Queen, this is a number made by His Majesty, which is used to replace the original Chinese characters, which is much more convenient when calculating." Zhang Shu replied.

Wang Qiang thought it was interesting, so she said, "How do you recognize this number?" ”

"It's very simple," Zhang Shu said, leaning over the table and writing down ten numbers from 0 to 9, then holding the paper in both hands and teaching Wang Qiang the numbers one by one.

Wang Du's family has tens of thousands of books, Wang Qiang basically reads all the books, and she is also a talented woman, and she usually helps Wang Du take care of the family's finances, but she also learns very quickly, and soon understands the use of this set of Tianzhu numbers, as well as the rules of carrying.

"Well, it's very simple, this is 123,500 yuan, isn't it?"

"I have heard that Niangniang is erudite and intelligent, and when I see it today, the old slave admires it."

Li Qi happened to come out of the bedroom at this time, and when he heard Zhang Shu say this, he couldn't help but wonder: "Hey, I didn't see that I was quite good at talking, why did I always look like an iron bone in front of me?" ”

"The old slave has been in the palace since he was a child, and he has been inspected since he was a child, and he has the ability to speak when he sees the wind and the rudder, otherwise he will not be able to survive in the palace at all. His Majesty likes Zhengchen, and the old slave is naturally it, if His Majesty likes sycophants, the old slave is naturally the traitor. Zhang Shu lowered his head and said quietly.

Li Qi looked at Wang Qiang and said with a smile: "The queen guesses that he is praising me or sarcastic?" ”

Wang Qiang said: "The words of the eunuchs are mostly admonishments. ”

Li Qi saw Wang Qiang holding the gift list in his hand, and immediately said: "Look at what that thing does, the royal reward is naturally measured by merit and usefulness, but it is not the kind of gift that ordinary nobles in their families." ”

Wang Qiang smiled and said: "The concubine body is just to see, and the good teacher knows it." ”

"What's the number?"

"Whoever has more money will always be good to move around more." Wang Qiang said: "After all, these rich people are well-informed, and they can do good business together." ”

Li Qi couldn't help but want to cover his face when he heard this, this is the queen of the world who married home? Or is it a big sister Dong who is ready to mix well in the business field?!

The teachers of the first phase of Jinyang Academy's junior pro-army academy have long been unable to teach them new things, and they basically rely on their own exploration, Li Qi is now a little idle, and basically goes to the academy every day to give students a half-day class.

Three years is enough time for students to finish arithmetic in school and basic geometry, physics and chemistry in junior high school almost early. After teaching the students simple refraction and reflection of light, as well as optical knowledge such as small hole imaging and concave lenses and convex lenses, the students polished prisms, concave lenses and convex lenses with the help of jade craftsmen, and developed telescopes and simple microscopes under continuous combination.

After teaching the students about chemistry with simple knowledge of acids and bases, the main task he gave to the students was to try to produce concentrated sulfuric acid, and only after making concentrated sulfuric acid could it be possible to make hydrochloric acid and nitric acid. The most basic three acids and two bases in inorganic chemistry cannot be produced at present, and this course cannot be continued for the time being.

Li Qi simply got back some of the coal tar obtained during coking and handed it to the students of the academy to try to separate the coal tar.

At present, all the iron-making workshops in Jindi and Shanbei are using coke for ironmaking or steelmaking, and Li Qi knows that coal tar is an important chemical raw material, so when designing and building coke ovens, he specially designed a tar recovery device. But now, coke ovens around the world are recycling more and more coal tar, a by-product of the coking process, and how to dispose of it is a headache.

If this thing is thrown out, it is extremely polluting to the environment.

So Li Qi said that let the students try to separate coal tar, and jumped directly from inorganic chemistry to organic chemistry.

In any case, he believes that there is never a law to follow in the progress of science and technology, and that production cannot be repeated according to the history of scientific and technological development in another world. The scientific and technological progress of mankind has been made by leaps and bounds because of a certain opportunity, and now there is Li Qi on the side to guide the direction for everyone.

What he needs now is for the students to discover all sorts of questions......

The chemical composition of the mixture of coal tar is so complex that Li Qi actually doesn't know what the students are making, but fortunately there is one thing he should recognize, which is kerosene.

Because kerosene is volatile, it is the easiest substance to separate when coal tar is dry distilled.

Now, kerosene lamps have gradually replaced the original vegetable oil lamps and candles, which have become the fuel used for people's night lighting, and kerosene lamps and glass lampshades are much better than lanterns. Since it was first used for lighting in horse-drawn carriages, this kerosene lamp with a glass cover is called a horse lamp.

Quiet as a virgin, moving like a tiger, a small fight is not interesting, it will only consume manpower and material resources in vain.

Li Qi is still in dormant and doesn't want to take the initiative. It's just that when he finds the right opportunity, he doesn't mind pounced hard and bites off a large piece of meat from his opponent's body.

For example, last year, they captured Youzhen and Zhen, and this year they won Sui and Yinzhou from the Dingyan Army.

As the strength increased, the generals under him began to be eager to try, but Li Qi was not as good as they wanted.

Xia Luqi and Fu Yanchao originally wanted to join forces in winter to take the opportunity to attack Cangzhou, where the southern army was weak, but after reporting to the court, they were like a stone sinking into the sea and there was no news.

Li Qi only stayed in Jinyang for about 20 days, then went to Xinzhou, and in winter, he still stayed comfortably in several hot spring manors in Dingxiang.

Outside there is a lot of snow, but inside the vegetable garden, it is warm as spring, and the eyes are full of green.

Li Qiming made a few side dishes in the dining room, and invited An Jinquan, Kong Qing, Zhou Guangfu and Lu Wenjin to have lunch together.

"Why don't I see you in the vegetable garden these days, the air inside is better than in the room." Li Qi asked after meeting Zhou Guangfu.

Zhou Guangfu couldn't help but smile bitterly when he heard this: "Knowingly, this queen will go to the vegetable garden on time in the morning and in the afternoon, and see that everyone looks like she wants to steal the official vegetables, who can stand this?!" ”

"Don't wronged people...... Li Qi poured tea for Zhou Guangfu with his own hands, "Let's try the new tea of Wu Di, I heard that it is Taihu Lake tea before the rain, the annual output is not much, and it is precious." After I see that the queen sees you, she will greet your old man first as a gift to the juniors. ”

"That's why it's troublesome, Weichen has to get up and return the salute respectfully...... It would be better if the minister was like the vegetable farmer and gardener in the garden. Zhou Guangfu sighed.

"Why didn't you see Tingyu coming over?" Li Qi asked.

Zhou Tingyu is Zhou Guangfu's nephew, and in terms of blood, he is the eldest grandson of Li Cunxiao. The little guy may have inherited some of Li Cunxiao's genes, and he has a lot of strength, only thirteen or fourteen years old, but he can already compete with adults.

"He kept Jinyang to study, and he will be admitted to Jinyang Academy in the spring, which has not passed this year, and he knows how to work hard." Zhou Guangfu said that the good famous general Miaozi may be because Zhou Deyu and Zhou Guangbi both died in the army, and Zhou Guangfu insisted on letting this little guy take the road of studying......
