Hearing Emperor Yong'an's words, Chu Yan's expression was obviously a little stiff.

He thought of the very flavorful topic he had discussed with Su Jinli before.

There seems to be a lingering stench on the tip of the nose.

Chu Yan had no doubt that if he dared to say Su Jinli's original words, Emperor Yong'an would definitely beat him.

So he said righteously: "Back to my father, my sons have been worrying about the construction of the city wall recently.

That day in the Marquis Mansion of Wuyang, Su Shi saw that Erchen was frowning, and was a little curious, so he asked Erchen why he was like this.

Erchen shouldn't have told her, but he thought of the bitter cold at the border pass, and it was not easy for the soldiers, so he couldn't help but mention it.

Who knew that she actually remembered it in her heart, and came up with such a strange thing as cement on a whim.

However, she was not sure at first, she just asked the people in the kiln factory to try to do it, and she didn't want to actually do it.

Father, this cement can be made, and the Su family can be said to be indispensable, so even though she is only a woman, Erchen still does not want to erase her merits. ”

When Emperor Yong'an heard this, he was shocked and at the same time, he couldn't help but feel a little complacent.

"She actually came up with it again."

He sighed with emotion, couldn't help but touch the beard on his chin, and thought with some pride: Is my vision too good this time?

Chu Yan secretly looked at his face, and seeing that he was in a good mood, he boldly asked him, "How does my father plan to reward her?" ”

"Well...... this"

Emperor Yong'an pinched his beard and suddenly didn't know what to say.

He was asked.

Last time he rewarded Su Jinli for the pencil, it's only been a few days?

And if you give it a reward, it will be too much to say.

But if you don't give a reward, it's a bit unreasonable.

Last time, the pencil was very important, but this time the cement is much more important than the pencil!

What reward should I give?

That's a hard question!

If he had given a reward openly, the royal historians would have impeached him again!

But Su Jinli is a deep boudoir woman, and it is really difficult to tell the world about such merits.

Otherwise, wouldn't all the whole world be talking about his daughter-in-law?

So Emperor Yong'an was very entangled.

Chu Yan saw his embarrassment, so he proposed: "If my father feels embarrassed, it is better to directly reward him with gold and silver treasures."

Su Shi is not an ordinary woman, she always has a lot of wonderful ideas in her head, if she has money in her hand, she may be able to come up with more useful things. ”

As soon as Emperor Yong'an heard this, his face became strange.

A girl in the Su family, does she like money so much?

It's not a glamorous hobby.

If it gets out, won't it make people laugh?

But...... Since she wants it, it's good to give it to her.

He can still get his hands on gold and silver treasure money.

So Emperor Yong'an gave Su Jinli one hundred taels of gold, five hundred taels of silver, and five thousand treasure notes.

The treasure banknote is a piece of paper for Emperor Yong'an, and he can print as much as he wants, so he doesn't feel very distressed.

However, he also knew that the treasure banknotes were depreciating badly now, and he didn't dare to print too much at once.

Gold and silver were rarer, so he had to reward much less for them.

Emperor Yong'an secretly thought, he couldn't give too much at once, otherwise what if Su Jinli tossed something rare next time?

Won't he have to say it again?

If you give too much this time, what will you do next time?

Of course, he also felt that Su Jinli should not toss out rare things so quickly.

Who knew the slap in the face would come too quickly!

On the second day, another good news came from the kiln factory: the coal stove that Su Jinli wanted was made! Including honeycomb coal as an experimental product.

The coal stove and honeycomb coal are not technical at all, and the kiln factory has been playing with too many things recently, so Su Jinli is not in a hurry to let them do this.

It was only after testing the cement yesterday that Su Jinli took out the drawings and recipes of the coal stove and honeycomb coal, and asked the director of the kiln factory to send two guys to do it.

This thing is really too simple, so I'll do it today.

Chu Yan got the news, and after running to see the finished product, he took it directly into the palace.

It just so happened that after the morning morning, he went to see the cement slabs and concrete slabs that had been poured yesterday, and they were not completely dry.

Now with this coal stove, it is just right to make Emperor Yongan feel at ease.

Emperor Yong'an was directly dumbfounded when he saw the coal stove and honeycomb coal, the corners of his mouth twitched, and he looked at Chu Yan a little speechlessly: "This coal stove and bee ...... Honeycomb Coal ...... Could it be that she is also ......?"

Chu Yan smiled slightly and generously admitted: "She wants to boil more hot water, but she feels that it is too much firewood." I also heard that the crushed cinders were very cheap, so I wanted to burn them with cinders.

But the cinders were too crushed and troublesome to burn, so she came up with this method to bond the cinders together and make them into a honeycomb shape.

Later, in order to facilitate the burning of this honeycomb coal, she came up with this special coal stove, which is particularly convenient to burn and very cheap.

Even the poor can afford to use this kind of coal stove and honeycomb coal.

Although this coal stove and honeycomb coal are inconspicuous, they are good things that benefit the country and the people and benefit the world. ”

So, Father, should you say it again?

Emperor Yong'an understood what he meant, and his face suddenly darkened.

He only secretly rewarded Su Jinli with one hundred taels of gold, five hundred taels of silver and five thousand treasure notes yesterday!

The second bastard still wants him to reward him!

When his money is blown by the wind!

Emperor Yong'an pondered for a while, and asked with some puzzlement: "Is Su Clan's money very tight?" How did you come up with the idea of using cinders? ”

His daughter-in-law, isn't it a little too picky?

He obviously gave so many rewards, is it necessary for the girl to slam the door like this?

How much firewood do you need to boil some hot water?

When Chu Yan heard this, he realized that he was exaggerating a little, and hurriedly remedied: "Actually, she thought of it before yesterday, and recently she invested all the money in her hand in the porcelain kiln factory, paper mill and Zhuangyuan Library, so her hand is a little tight." ”

Emperor Yong'an suddenly realized.

However, if he knew about the daily entry of Su Ji Soup Pot Shop and the registration fee charged by the Jinshi training class, he would probably be so angry that he would beat Chu Yan up.

Chu Yan continued: "Erchen thinks that this coal furnace and honeycomb coal can be promoted throughout the country and benefit the people of the world.

Neither of these things is suitable for long-distance transportation, so Erchen thought that he could set up a patent department to apply for patents for coal stoves and honeycomb coal, and merchants from all over the country could use this patent as long as they paid a certain amount of gold and silver to the patent department. ”

Emperor Yong'an was dumbfounded again.

He looked at Chu Yan in surprise, and suddenly felt that this son was a little strange.

"What is the Patent Division? As far as I know, whenever something is profitable, those merchants will rush to copy it.

This coal stove and honeycomb coal are easy to make, and you can understand at a glance, how can those businessmen obediently pay for it? ”
