Requite?

Shi Laodao wants to reciprocate.

That's right, others have worked hard to experiment, Han Jiang estimates that after 800 years of 19 layers of sand and gravel in this bamboo tube, the water purifier will be at this level. It is also appropriate to give something in return.

Han Jiang replied: "Five hundred? ”

Shi Ziyan: Hehe.

Han Jiang: Hehe.

The two laughed dryly, Shi Ziyan gave Han Jiang a piece of paper, on which was written a math problem with some complicated words, Han Jiang didn't know what it was for, but it was not difficult to solve it with binary quadratic equations.

Han Jiang listed an equation, and then explained the way to solve the equation to Shi Ziyan.

Shi Ziyan solved this problem in only five minutes.

Shi Ziyan asked: "Brother Jiang seems to have studied the mirror, and the craftsmanship of the bronze mirror has reached the extreme, and there has been no progress in a hundred years. ”

Han Jiang stood there with his arms crossed, thought for a moment and said, "The mirror does have other progress, but the time is not right. At the moment, there is a kind of way, if the Taoist understands the stainless technology of the bronze mirror in the Qin period, then it is possible. This process I call the chrome runout. ”

Han Jiang had seen it in the museum in his previous life, and the two-thousand-year-old Qin sword was stainless and very sharp.

Shi Ziyan replied: "I understand, I have a disciple under my sect who used to be a swordsmith before following me. ”

Han Jiang said: "With wrought iron, plus a purified metal from my Han family, it is called zinc. I don't know the ratio of wrought iron to zinc, but I do know that this thing can have a mirror surface depending on the way it is processed, whether it is ground with cloth or wood. If you add Qin Jian's stainless technology, it should be very good. ”

"Of course, this is just a theory, and I don't know if it will be successful."

Shi Ziyan took note of Han Jiang's words.

Lu You said on the side: "If you can succeed, you can give a gift to Concubine Jin next year." ”

Han Jiang grinned: "Of course, as long as she accepts it, we don't dare to say much about this kind of thing, and we guarantee it every year." The extreme of the mirror is definitely not copper or iron, but made of a kind of stone, more on that later. ”

Han Jiang doesn't know how to make glass, he only knows that glass is something fired out of quartz stone.

I don't know anything about the process at all.

However, I believe that if he sees quartz stone, Shi Ziyan should be interested in studying it.

As for the mirror that Han Jiang just said, to put it bluntly, it is mirror stainless steel.

Of course, whether it can succeed or not, Han Jiang has no confidence at all, maybe he can, maybe he can't. The only thing I can support is money, and the rest can only rely on Shi Ziyan.

At this time, the second plate of pure white salt succeeded again.

Shi Ziyan is very satisfied with the result: "It seems that this multi-layer sand and gravel purification method is correct, but I don't know how long it can last, or how many catties of coarse salt water should be poured and cleaned with clean water after being used." ”

Lu You suddenly frowned: "What will happen if this thing reaches Lin'an Mansion?" ”

Han Jiang had an indifferent expression: "What else, like the evil Han Mansion will definitely spend money to buy it." Ordinary petty officials who will buy this, their money is only a few dollars. Therefore, it is our Han family who is still the scourge, just come on, my Han family is not afraid of being harmed. ”

That sounds .......

Very.

However, it seems to make sense.

Han Jiang laughed: "That's it, whoever has no money and wants to be greedy, just close the door and let Shen Yuran go and bite them to death." ”

Sounds even weirder.

But, it really makes sense.

Shi Ziyan and Lu You glanced at each other, and both of them were filled with an indescribable strange feeling in their hearts.

Han Jiang put his hands in his sleeves: "Teacher, Dao Chief, you guys tidy up first." I'm away for a few days to deal with something shady. Teacher, if you promise not to get angry or not to hit me, let's go together. ”

Lu You asked, "Where?" ”

"Yushan."

Hearing that Yushan Lu You knew, he had heard Han Jiang mention it before, and he detained two Japanese boats.

Lu You asked again: "How do you avoid Shen Zhengyan?" ”

Han Jiang replied directly: "Don't avoid it, he is sick, in fact, he is a heart disease." Just enough to give him two days off. What's more, I didn't plan to leave openly, so I took a boat from here to the east late at night, and turned back in a day at most when I arrived at Yushan Port, and I found a reason to stop it. ”

Lu You said: "Get on the boat first for the teacher, you go and see Shen Zhengyan." ”

Han Jiang didn't understand: "Teacher, I don't understand. ”

Lu You explained: "What is the most difficult thing about being a good official? I have experienced it as a teacher, and I have once judged a case if it is against both sides of the Song law. But if we look at human nature, both sides are not only wrong, but they are both doing the right thing. This kind of case made the teacher unable to eat and sleep for ten days. ”

Hearing Lu You say this, Han Jiang nodded: "I understand, I'll go see him, so that he won't be able to eat or sleep for ten days." ”

"This!"

Lu You wanted to say that he wanted Han Jiang to persuade Shen Yuran.

Obviously, Han Jiang misunderstood.

Han Jiang's idea was to double the torture of Shen Yuran.

Han Jiang ran away happily.

A quarter of an hour later, the inn.

Lang Zhong gave Shen Yuran a needle and prescribed a few pairs of medicines, and at this time, Shen Yuran was standing in the courtyard wearing a piece of clothing, holding a flower branch in his hand.

This kind of flower is called a gold belt, and Han Jiang feels that this flower is very similar to a spring flower, and he doesn't know if it's the same kind.

When Han Jiang arrived, Shen Yuran stood still, still looking up at the moonlight.

Han Jiang also folded a flower and stood beside Shen Yuran, and then pulled off a petal: "Han Jiang is a bad person." "One more piece:" Han Jiang is a good person. Again: "Han Jiang is a bad person......

Only then did Shen Yuran turn his head.

Han Jiang and Shen Yuran stood side by side: "Have you heard of Zhu Wen?" ”

Shen Yuran didn't answer, and Han Jiang continued: "Zhu Wen of Houliang. Shen Yuran nodded.

Han Jiang noticed that there was a pair of shoes behind the bushes, men's shoes, and the quality was not bad.

At this time, Han Si and Han Wu followed, if someone secretly told them, they would definitely stop it, if not, let them eavesdrop there, there was only one possibility.

Cui Yiye.

One sheep is also herded, and two sheep are also released.

Han Jiang didn't care that Cui Yiye stood behind the bushes and spoke:

"I'll tell you a story. In order to raise military spending, Zhu Wen doubled the salt tax, with a minimum of 200 wen and a maximum of more than 400 wen in a catty of salt market. There was a smuggler who sold salt for 150 wen at first, and later he began to sell salt for 40 wen a catty, and after he couldn't buy cheap smuggled salt, he lost money and kept selling it for 40 wen a catty. ”

Han Jiang glanced at Shen Yuran: "Question: Illegal salt is a felony, this salt dealer has violated the law of Houliang." How to convict. ”

Shen Yuran clutched his chest, he felt very uncomfortable.

This case is too extreme.

On one side is the law, and on the other side is the conscience.

Han Jiang said again: "Do you know why I specially asked Wang Shangshu to come forward and let you accompany me before I traveled?" You only know impeachment, impeachment for impeachment's sake. What is a mirror? ”
