Luan Yu, the king of Han, came to this place surrounded by the guards of Ouchi. It immediately caused a commotion among the craftsmen in the complex.

In front of the scorching stove, a stout man in a leather apron, holding a huge hammer, was striking iron, clanging, sweating profusely.

"Old Chen. I heard that the king is coming. Let's take a look. A sturdy man next to him threw a hammer and planned to join in the fun.

"What's there to see. The king is not yet a nose and two eyes? Lao Chen didn't have a good air, but a pair of eyes that showed longing betrayed him.

"Although they all have a nose and two eyes, they are kings. I've never seen it in my life. Now it may be the only time. I'm leaving. Keep striking the iron. ”

The sturdy man shook his head, unbuttoned his apron, and ran out.

"Wait for me." Lao Chen thought about it, this may be the only opportunity in this life, so he was in a hurry, so he hurriedly threw the hammer, unbuttoned his apron and rushed out.

Within this complex, there are a large number of craftsmen. Mainly blacksmiths and carpenters. Although heavily guarded, the soldiers were afraid of causing a commotion and rushed into the king. Therefore, he tried his best to prevent the craftsmen from going out to see the excitement.

But it didn't work.

These strong craftsmen, with great enthusiasm, broke through the human wall composed of soldiers and came outside to watch the Han King Luanyu.

Han Wang Luanyu stopped five hundred meters away. The Ouchi guards who followed showed a look of vigilance and waited for the battle.

After the Ministry of Industry Shangshu Ma Youguang received the report, a layer of fine sweat appeared on his forehead. Riding a horse before coming to Luan Yu, he first explained the matter. Then he said, "King." Please let the minister go first, and restrain the craftsman. Prepare to welcome the king. lest the craftsman run against the king. ”

Luan Yuzhong. Wu Nian sat cross-legged with a smile on his face, and said to Ma Youguang outside Luanyu: "It's okay. Aren't the craftsmen who can come here all of them go through layers of scrutiny, and it is determined that there will be no spies from Meng Yuan or Chu State? ”

"They're all reliable. Besides. They are here for the sake of the country, and they have merit. Now I just want to see the widow's face, the widow. How can you avoid it? ”

"The team continues to march."

"Yes."

Ma Youguang wiped his sweat when he heard this, and no longer hesitated. After answering the call, he rode forward and led the team forward.

In modern society, everyone involved in the military industry has a scrutiny.

They all have to be innocent in family affairs and have no criminal record.

Wu Nian is very concerned about these secret projects in the Ministry of Industry, bottles and cans. The scrutiny is very strict.

The craftsmen were excited, but when they saw Luan Yu coming slowly, they also calmed down. Then I don't know who knelt down first, and soon knelt on the ground.

"The King."

Luan Yu stopped in front of the craftsmen. Wu Nian, who was wearing a dragon robe, stepped on the small bench and got off Luanyu, looked at the black crowd in front of him, held his hands weakly, and said, "Everyone, you are exempt. ”

"Thank you, Your Majesty." Someone took the lead, the craftsmen stood up, and then they all secretly looked at Wu Nian.

Wu Nian smiled and said, "The face is for people to see." You can see it if you want. The widow is standing here. ”

After listening to Wu Nian's words, the craftsmen became excited, and looked up at Wu Nian generously.

Some whispered.

"The king is really mighty."

"Impressive."

"What mighty, majestic. That's what describes a military general. To describe the king, it should be said that he is graceful and luxurious, and he has the bearing of an emperor. ”

Wu Nian smiled dumbly, and after a while, the officials of the Ministry of Works stepped out and let the craftsmen go back to work. Ma Youguang breathed a sigh of relief and led Wu Nian to a small courtyard.

The Ouchi guards who came with them immediately dispersed, and the water around the small courtyard was blocked.

The Ouchi guards brought a Taishi chair, a coffee table to put down, and a kettle to put down. Wu Nian sat down unceremoniously and drank water from his cup.

Ma Youguang lowered his head slightly and stood aside. Soon after, a team of craftsmen walked in with a lot of tools and materials.

In front of Wu Nian, they used a grinding tool made of wood, mixed cement with sand, and then poured it into the grinding tool, and when the cement solidified, it was a stone slab.

Cement is a thing that Wu Nian is more familiar with. Nothing curious. But there is one issue that is critical. He looked up and asked Ma Youguang, "How long does it take to solidify?" ”

"In about six hours, it will solidify."

Ma Youguang replied in seconds.

"Good." Wu Nian nodded with satisfaction, this seems to be similar to the cement of modern society. After thinking about it for a while, Wu Nian said to Ma Youguang seriously: "First. Immediately invest manpower and material resources to increase production. ”

"Second. Excavate the sand on the reserves. ”

"Third. Mass production of oligocratic steel bars. ”

"This thing. It is human flesh, and steel is human bones. Steel bars are made of bones to be truly strong. ”

"Lord Ma. You are the secretary of the Ministry of Works. This court, all kinds of buildings, are all handled by you. You should understand the magic of this thing. ”

Ma Youguang showed a solemn expression, bent down, clasped his fists and saluted: "Don't worry, the king understands." ”

Leave aside the king's messy ideas, like the steam engine. This cement is wonderful.

To build a platform, the court also needed to cut stones. The stones have to be good material.

This cement and sand and water not only save time and effort, but also are no worse than stone.

What a stroke of genius.

And the blast furnace steelmaking.

People say that our king, that is the tiger. Brave and good at fighting. Who knows, our king is still Lu Ban alive, and he is a skilled craftsman.

I haven't seen this thing, it's just a thing on paper. After reading it, Wu Nian knew it in his heart.

Ma Youguang has outstanding ability, and Wu Nian is very relieved to hand it over to him.

Immediately, Wu Nian asked Ma Youguang to take him to the courtyard where the steam engine was studied to watch.

After reading it, Wu Nian could only say that it was a pile of scrap iron. He had already told the craftsman everything he knew about the principle of the steam engine.

But he didn't know much about it, let alone the exploits of this era. The parts needed for the steam engine had to be forged by hand by craftsmen.

It's a lot of trouble.

Whether the steam engine can come out is still a question, and even if it does, it will be the year of the monkey.

However, Wu Nian was mentally prepared for this and was not disappointed.

After leaving the steam engine, Wu Nian visited other projects for which he provided ideas, took a big circle, and set off back to Jiangxian before dark.

"Everything is ready, only the east wind is owed. It's time to study how to attack Meng Yuan. "Luanyu is very large and relatively stable, but the carriage of this era is inevitably bumpy. Wu Nian sat cross-legged in Luanyu, his body swaying with the bumps, and he lowered his head slightly and groaned.
