Datang: You Can't Imagine the Happiness of the Prince

Wan Kuan, on the other hand, is staring at this operation with extremely sharp eyes. Passivation is necessary. The passivated roller is not afraid of high temperature, but directly rolls steel.

But this sulfuric acid is too dangerous, and Wan Kuan can only do his best to protect these craftsmen.It looks good now.

And Li Shimin looked at his serious son, and as soon as he saw Wan Kuan's eyes, Li Shimin knew that Wan Kuan was a person who did big things and was persistent.

Li Shimin felt a little emotional in his heart, such a son is worthy of being his own prince.

The craftsmen over there moved very quickly, because Wan Kuan specially explained in advance that everything was stable and fast, and the longer it dragged on, the easier it was to get into trouble.

The two rollers were doused with green alum oil, and the big man immediately put the jar outside the door.The other big men rolled the two rollers immediately, so as not to condense the green alum oil on one side.

And after the big man came back, Wan Kuan directly asked him to take off his fur, and hurriedly went to the water room inside to wash himself with water.

On the other side, that old Feng told all the big men to stay away from the rollers.Everyone scattered, Lao Feng held a leather pipe and began to sip water against the roller.

At this time, Wan Kuan took off the wet wipes from his face, and it was finally safe.Now just wash off the green alum oil left on the rollers.

At this time, Li Shimin walked over quietly and asked, "How did the water in this pipe come out?"

Wan Kuan glanced at Li Shimin, he was really stupid, he didn't know this.

"Your Majesty, hang the water tank a little higher, and then the water will naturally flow down!"

"Wonderful!" Li Shimin couldn't help but nodded.

Wan Kuan turned his back and pouted quietly, what is this?Isn't this common sense?

What Li Shimin sees now is such a novelty. The molten steel coming out of the blast furnace has an orange-red appearance, and when it reaches the crucible mold, it becomes a fine steel billet.

"Wan Kuan, how many steel blanks can you practice in one day?" Li Shimin asked with great interest.

"Your Majesty, as long as there is enough iron ore, [-] catties a day!"

"What? Ten thousand catties?" Li Shimin's mouth was big enough to swallow a whole apple.

Wan Kuan sighed inwardly, he had never seen the world.Ten thousand catties a day, but only five tons.There are five blast furnaces in this supervisor, and only one ton can be trained, which is very few.

Wan Kuan was extremely dissatisfied with this output, but Li Shimin was astonished.

How did Li Shimin think of his son at this time, and how did he like it.Li Shimin's eyes are full of kindness, this is his seed!

And when Li Shimin saw Wan Kuan instructing the craftsmen to roll the billet with the two big rollers just now, his eyes were about to fall out.

The red-hot billet in the blast furnace fell between the two fixed rollers.With a thud, it became thinner.

The strong men at the front and back used iron pliers to push the billet, rolling it back and forth again and again.When the temperature of the billet cools down, it has become a thin layer of steel plate.

Li Shimin looked at the huge steel plate in front of him and couldn't close his mouth.Isn't this steel plate knocked out all at once?How can you get so much out of it all at once?

At this time, Li Shimin looked at Wan Kuan, who was commanding the work. Now he can't wait to go up and hug his good son.

===Chapter 70 This is the young lady===

Datang officials can only take a day off in ten days, but there are many holidays on weekdays.But for Wan Kuan, every day can be a rest day.

Now that the prisoner is on the right track, Wan Kuan doesn't have to stay there every day.Yu Shaojian and Lao Feng really have two brushes. Wan Kuan casually instructed them like this, and they understood.

Wan Kuan didn't want to go today, so he stayed in his Taipingfang mansion.

"Master, don't you have to go to the yamen today?" Xiao Laizi looked like a dog.

"What are you going to do? Can't you rest at home?"

"But those relatives go to the yamen every day, and the people praise them for their diligence."

"Those are all incompetent people. They have sorted out all government affairs. What are they doing? They are all people who want to show their prestige. If they don't go to the yamen, who will they show their prestige?"

"Young master is mighty!" Xiao Laizi's flattery came as soon as he opened his mouth.

Wan Kuan was a little proud, and was about to speak when he heard a commotion outside the door.

"What's the matter? Go and see!"

As soon as Wan Kuan walked to the backyard, he saw his housekeeper busy at the back door.Wan Kuan is a little strange, why did someone make trouble when he moved to Chang'an?

Wan Kuan strode over, and as soon as he reached the door, Wan Kuan was overjoyed.

It turned out that at the back door, there were two girls disguised as men, who were the sisters of the Wu family.

"What's the matter? Please come in as soon as you see the distinguished guest!"

Wan Kuan walked in and talked to the old butler, who was also quite helpless.

"Young man, the old man knows that this is a distinguished guest. But the guards in Chang'an Mansion are all new, they don't know each other, so there is a misunderstanding."

Wan Kuan gave the housekeeper a blank look after hearing this: "This is your housekeeper's person. In the future, you will train and train your subordinates well."

After speaking, Wan Kuan directly took the blushing Wu Shun'er by the hand and entered the backyard.

That Wu Shun'er was so pulled by Wan Kuan that she couldn't hold her head up.How embarrassing these people are!

Wan Kuan dragged Wu Shun'er all the way forward, while Wu Mei'er followed behind and kept pouting.

And Xiao Laizi winked at the old housekeeper, while the old housekeeper sighed.

"Be smart one by one, who will let you in and who won't. The old man has already told you." The old butler shouted at the gatekeepers and guards with some dissatisfaction.

"Do you know who you stopped just now? That's the future young grandmother. Do you think the two holes on your nose are out of breath? You're young, you don't have eyes, and I'm not as good as an old man. !"
