What Su Cai'er said made Zhao Ce feel warm in his heart.

From Shuiqiao Village to the capital, everything seems to have changed.

Their identity has changed, their status has changed, and the people and things around them have also changed.

But the only thing that didn't change was the warm person he was holding in front of him.

No matter what happens outside, Zhao Ce can always calm down quickly as soon as he returns home.

Zhao Ce gently pressed Su Caier's little head on his shoulder, lowered his head and kissed the top of her hair.

"My dear, these words from you are enough."

Su Cai'er raised her head in his arms and kissed her husband's chin.

Zhao Ce feels that as a time traveler, he considers himself to be better than many people in ancient times.

He has a solution for this trivial matter.

It’s just that everything has been going too smoothly for me.

At this moment, I really felt a little emotional.

Zhao Ce thought of the Duke Yan of Confucius whom he had visited before, and he couldn't help but sigh in his heart.

Dynasties change, being reincarnated as an emperor, and being an uncle are actually not very important.

Only by being a great Confucian who has been passed down through the ages can we truly settle down and live in peace.

But the great Confucians are not so easy to do...

Zhao Ce thought for a while and asked someone to bring the Four Treasures of the Study.

Su Cai'er was grinding ink beside her and watching Zhao Ce write a letter.

"Husband, do you want to write a letter back?"

Zhao Ce said "Yeah".

"Write a letter back and ask Brother Vincent to use part of the revenue from our store to build a private school in the village."

"We can't control other people, but I want our children in Shuiqiao Village to know how to read and be able to read."

After speaking, Zhao Ce glanced at Su Cai'er.

"It would be nice for the girls in the village to learn some words too."

Su Cai'er frowned and had no objection to her husband's decision.

After learning that she was pregnant, Su Caier had already written two letters to Mrs. Li and sent them back.

Now that she saw her husband writing, Su Caier simply took a smaller brush and wrote a letter next to it.

Regarding the matter at the charcoal kiln, after Zhao Ce wrote the letter and sent it back, he wrote another letter to Liu Mansion explaining the matter.

However, Liu Daxia has been busy with border soldiers spending the winter recently, so he has been staying in the palace and has not come back for the time being.

Therefore, Zhao Ce was not able to receive a reply on the same day.

Snow was falling again outside the door, but the two people inside were not affected at all.

Occasionally there was the sound of paper being turned and the sound of whispered conversations.

After writing the letter, Zhao Ce began to think about coal washing.

Rich people use high-end and safer charcoal basins.

These are naturally not customer goals.

Coal in ancient times was not used daily by the people. The reason is simply that most of the unwashed coal contained deadly poisonous gas.

Therefore, this coal must be "washed".

If unwashed coal is used, a special chimney or stove must be used.

In this regard, Zhao Ce also compiled two sets of plans.

One set is sold with a stove with a chimney.

People who choose this plan can directly buy the rough-selected raw coal and process the briquettes themselves.

There are also disadvantages to using a stove, that is, the temperature will be lower than burning coal directly.

But this is better than not having anything for heating, and raw coal is cheap.

The other set is to make a coal washing machine.

The remaining coal water after washing the coal is processed into briquettes at the coal mine and then sold.

In this way, the toxic substances contained in the washed briquettes will be greatly reduced.

Modern coal washing machines are large, but the structure inside is not very complicated.

The most important thing is the "cyclone".

In ancient times, when there was no electricity, everything had to be done manually.

Zhao Ce plans to go to the blacksmith in the capital tomorrow to discuss the matter of this machine.

After the excavated coal is screened and dehydrated by machines, the clean coal can be used to make steel to improve the quality of the steel.

Zhao Ce expected that the most important thing was to use it to make weapons.

After the quality of coal is improved, the quality of the steel produced will be better, and the quality of weapons will also be significantly improved.

and.......

The Ming Dynasty already used firearms extensively on the battlefield.

However, the quality of this firearm has never been improved, and the reason is the quality of the steel.

Ordinary coal is used in smelting. Because there are too many impurities, the smelted steel also contains a lot of impurities.

Therefore, the quality cannot be greatly improved.

To significantly improve steelmaking technology, other alloys must be used.

Of course, these are too complicated, and Zhao Ce doesn't have much clue at the moment.

It's just that the quality of the smelted coal has improved, and the quality of the smelted steel will be significantly improved. This is for sure.

Medium coal is cheaper than clean coal and can also be used to make steel and make some ironware for folk use.

The remaining coal gangue is one of the raw materials for making cement.

During the coal washing process, the water left behind by washing the coal is "coal slime". After being mixed with yellow mud, it can be made into briquettes.

In short, if this coal mountain is developed, it will be a real treasure!

It is very meaningful not only to myself, but also to the whole society!

Zhao Ce was thinking and writing and drawing on paper from time to time.

After Su Caier finished writing her letter, she lay aside.

He didn't say anything, and looked intently at his husband's thinking.

The husband frowned slightly, the way he looked when he was thinking about something was so beautiful...

Feeling the gaze of the people next to him, Zhao Ce turned his head and glanced casually.

Before Su Cai'er could take back her piercing eyes, the two of them looked at each other.

Su Cai'er subconsciously smiled at him, the small pear dimples at the corners of her mouth pursed lightly.

Zhao Ce looked at the infatuated love in the little girl's eyes that he couldn't take back in time, and he touched the little pear dimple at the corner of her mouth with the tip of his pen in a funny way.

"What are you doing looking at me?"

"If you're tired, why don't you go to the lounge chair next to you and lie down?"

Su Cai'er pouted and tipped the tip of his pen.

"I'm not tired."

"I'm looking at my husband, just keep doing your thing."

Zhao Ce thought to himself, his little wife is standing beside him with an adoring look on her face, looking at you intently, which man can still concentrate?

Having finished thinking about the matter, Zhao Ce simply put down his pen.

"Forget it, it's almost done."

"Tomorrow I have to find a carpenter and a blacksmith, and then have a look over at Coal Mountain."

"Wait until the day after tomorrow before I go out with you to buy new year's goods?"

Zhao Ce sat down and held Su Caier back in his arms.

Su Cai'er said: "It doesn't matter. My husband is busy, so I can take care of it myself."

Zhao Ce touched her little face.

"I told you before in Fucheng that I would take you riding horses to the mountains, but I have never fulfilled this promise."

Su Caier said with a smile: "My husband took me horse riding many times on the road. It was fun and I liked it very much!"

Zhao Ce smiled and kissed her: "Why are you always satisfied so easily?"

"My husband has not done what he promised you, so you should mention me."

Su Cai'er whispered: "But I really don't care."

Zhao Ce said helplessly: "Well, I can only remember it after spring."
