Because this is his own weapon, the masters are responsible for quenching, and after quenching, it must be cooled naturally, so Zou Yu left.

The finished weapon was only delivered to Zou Yu on the fifth day, Yuwen Rutong spent a lot of effort, he used a male and a female, two tigers, and the blood of the whole body was quenched.

"One male and one female, yin and yang balance, the essence and blood of the tiger, can add to the murderous aura of the weapon and make the enemy fearful!" Yuwen Rutong introduced with a little smugness.

Zou Yu knew that quenching with blood increased the carbon content in the weapon, so the hardness was higher, but he knew that Yuwen Rutong was also kind, so he smiled and thanked him for his efforts.

"Dang!" With a sound, Zou Yu withdrew the steel knife in his hand, looked at the gap on the steel knife, and nodded with satisfaction while looking at the trace on the stick that was fading and disappearing.

Although this stick is made of copper, its hardness is not lower than that of ordinary pure steel, and because of the blood, the dragon-shaped lines on the stick are vivid, and it also exudes a fierce momentum.

A hollow tube made of steel and copper of the same material, located at the joint, is integrated with the stick, and after the hands of the craftsman, it only needs to be twisted to firmly turn into a long stick one zhang long.

"Man! It has to be long and hard! Zou Yu put down the stick with great satisfaction.

Xi Junmai, who was also carrying a coiled dragon stick, took the double stick and stood aside.

"The two of you came together, bringing good news again!"

"The prince is wise!" Yu Wenwen smiled and arched his hand.

"I love good news!" Zou Yu said happily. There is a lot of good news during this time, which is something to be excited about.

"What's the good news this time?" Zou Yu asked expectantly.

"It's a paper mill! The prince used salt alkali to make the paper whiter, and steaming made it easier to make, but the final molding must be carefully pulled out of the pulp from the pool, even if there is still uneven thickness. Yu Wenwen said.

"Not bad."

"This mainly requires the craftsman to have a steady hand and even speed, so the average craftsman can't do it, which limits the production of paper."

"That's true."

"Therefore, Xia Guan uses a waterwheel to drive the bamboo plank, so the speed is very stable." Yu Wenwen explained.

"Not only that, when you do it manually, because of the width of your arm, the paper can't be too big, but when you do it with a water wheel, you can make it very wide, and you don't have to put it together because of the width of your arm." Yu Wenwen continued.

"Pretty good!" Zou Yu praised.

The massive use of equipment and the liberation of more labor are one of the signs of industrialization, even if it is just pure water power, it is enough for Zou Yu to be satisfied. This at least means that he has been ahead of his time and is gradually changing the world.

These are all things that are beneficial to the people and the military, and even if he fails in the fight for the world, those who come after him will not turn a blind eye and abandon them.

If the extensive use of waterwheels can be popularized all over the world, the people's ability to resist drought will be much higher; Intensive farming, grain production has increased greatly, the people are less hungry, and even if they are exploited, there are still vegetables and fruits, and life is much better.

As long as all this is promoted, the people of the Central Plains will benefit from the era, and anyone who wants to enter the Central Plains will be easy to deal with the Hu people of different races.

"Lord Qiyu, the cotton deseeding machine has been made, but there is no suitable manpower for spinning and weaving." Yu Wenwen continued.

"If you don't recruit it, there should be so many women who are willing to work, right?" Zou Yu was stunned for a moment and asked.

"This is not what Xia Guan means, Xia Guan means that there are no skilled women." Yu Wenwen waved his hand and said.

"How is that possible? There will be no clever woman who knows how to weave in Jinyang! Zou Yu smiled dumbly.

The most famous thing in the Central Plains is silk, such a big industry, Yu Wenwen actually said that he couldn't find a good woman, no wonder he laughed.

"Lord Wang, silkworms are mainly produced in Shuzhong and the south, and there is only linen cloth in the north." Yuwen Rutong reminded.

"I see, I forgot about it." Zou Yu patted his forehead lightly and said.

As soon as Yuwen Rutong said it, he understood that there was no market, so there were no good talents, and ordinary people were definitely not so particular about wearing linen clothes. Only those who make silk will strive for excellence.

"There should be one in the palace, right?" After thinking for a while, Zou Yu asked.

"Definitely." Yuwen secretly breathed a sigh of relief, and hurriedly nodded and said.

Seeing Yu Wenwen's appearance, Zou Yu reacted at this time, he was clearly coming for the people in the palace, where could he not recruit people.

"Alright! I went to the palace to ask, and if there were, I was transferred out as a master and taught a group of people to come out. Zou Yu said a little speechlessly. After speaking, Zou Yu got up and entered the palace.

There is something in the palace, and there is no shortage of Concubine Wei, whether it is a mirror or a delicacy. In the palace of Concubine Wei's bedroom, the windows have been completely replaced with glass, and the light is much better than before.

"There are more than 20 embroiderers in the Shangyi Bureau, all of whom are good at weaving and embroidering, I am alone in the palace now, I don't need to keep it, you can transfer them out." There was no one in the hall, and Concubine Wei said as a little bird leaning on Zou Yu's arms.

"Good!" The matter was easily solved, Zou Yu looked at the lovely person in his arms, couldn't help but move his index finger, and lowered his head to print it.

"Hmmm! Well! Concubine Wei stretched out her hand to wrap her arms around Zou Yu's neck and responded enthusiastically.

Thunder and thunder! Originally, it was an inevitable gut war, but the accident still happened.

"Gross! Vomit! Concubine Wei, whose eyes were watery, suddenly felt uncomfortable in her heart, something came up, and she quickly sat up and covered her mouth and retched.

"Does my mouth stink that?" Zou Yu looked at Concubine Wei with black lines.

"I... Vomit! Vomit! Concubine Wei turned her head and looked at Zou Yu apologetically, and just as she was about to speak, she couldn't help but retched again.

"What's wrong? Uncomfortable? I'll call the Imperial Doctor right away. Zou Yu found that something was wrong with her, and hurriedly stepped forward to support her and asked with concern.

"Don't! Other! Concubine Wei hurriedly grabbed Zou Yu.

"How can this work? If you are sick, you have to see a doctor. Zou Yu frowned.

"I... I'm not sick! A flush floated on Concubine Wei's face, and she stomped her foot lightly and said.

Looking at Concubine Wei's surging trembling, Zou Yu swallowed his saliva, came back to his senses and asked, "You have it?" ”

"Hmm!" Concubine Wei lowered her head shyly, like a mosquito.

"Hey, hey! Sit down! Be careful. When Zou Yu heard this, he was very happy, and hurriedly and carefully helped Concubine Wei to sit down.

"How long has it been, why didn't you tell me!" Zou Yu asked with concern.

"I don't know, I... I also found out just now, and I reacted the same as when I had a child. Concubine Wei touched her stomach with a happy smile on her face and said in a low voice.
