Looking at his appearance, Yongning and his aunt Jiang Wan'er couldn't help laughing.

After eating, Zhao Hao took a shower, then joined his mother and the others to play a few rounds of mahjong.

They stayed at home until the sixth day of the New Year, and then the three of them returned to the princess's mansion.

This time, Yongning couldn't stand it anymore, so he took him into the room and gave him a tiger bench and pepper water beating.

After being away from home for a long time, he did show some fighting ability.

This was something Zhao Hao had not expected.

However, in the end, he still suffered a great loss, and a terrible loss.

Originally, Zhao Hao had the habit of calling people by that name.

However, facing Yongning, he still didn't dare.

If he dared to ask, and Yongning impulsively agreed, he would become the late emperor's retired emperor.

This is a big problem.

After finishing, Zhao Hao hugged Yongning and had a sound sleep.

On the seventh day, Zhao Hao hosted a banquet at the first floor for Wang Mengyu, Zheng Zhiqian, Luo Bi and Xiao Chuyun.

When Luo Bi heard that Xiao Chuyun was involved in this game, he was a little reluctant to participate.

After all, his identity is here.

Not as good as Wang Mengyu, nor as good as Zheng Zhiqian.

However, Zhao Hao still let him participate.

He has already handed over all matters concerning business channels to the other party.

The few of them decided to leave Beijing together on the eleventh day of the first lunar month and return to Qinzhou.

Wang Mengyu and Zheng Zhiqian, as well as Xiao Chuyun and Luo Bi, were all surprised that Zhao Hao was going to go there.

Zhao Hao explained: "Nothing much, just go over and take a look at the manufacturing of the curved plow."

Wang Mengyu even said, "Brother Hao, it's just a small matter, why do you need to go there in person?"

"Old Zheng and I can take care of it!"

Zhao Hao said, "You two are also responsible for recruiting miners. I guess you are too busy to handle it."

"I can help you when I get over there."

Hearing what Zhao Hao said, Wang Mengyu nodded: "That's great!"

In a blink of an eye, it was the tenth day. Zhao Hao, Wu Song, Wang Mengyu and Zheng Zhiqian left Beijing and went to Qinzhou.

By the time they arrived, it was already past the 15th.

After arriving, Zhao Hao summoned all the best craftsmen.

Then he took out a blueprint from his sleeve pocket.

"Everyone, I have only one request, please cast this thing for me."

"This drawing has various specifications, such as size, thickness, length, thickness, etc."

"Another point, this matter must be kept secret. If anyone leaks the news, don't blame me for being rude!"

"You guys make the molds first, and I will open a new independent smelting workshop for you."

In fact, it is not a new construction, but an area isolated from the original workshop.

This area cannot be entered or exited at will, and can only be entered with a token.

Seeing Zhao Hao's actions, Wang Mengyu and Zheng Zhiqian rushed over immediately.

Wang Mengyu said to Zheng Zhiqian: "Sure enough, you are right again!"

"Brother Hao came to Qinzhou with us because he really has something important to do!"

Zhao Hao looked at the two of them and said sternly, "You two, remember this. This area, even if you two enter or leave, you must use the token."

"Also, every craftsman here will be assigned a guard."

"It's both protection and surveillance. Nothing in here can be spread out."

"Did you understand?"

Seeing that he spoke so seriously and formally, the two of them immediately understood that Zhao Hao must be doing something huge here.

Wang Mengyu quickly said seriously: "Brother Hao, don't worry, with the two of us here, we will make sure everything is safe!"

Zhao Hao said, "Old Zheng, you also understand that the Wu Kingdom has been keeping an eye on our smelting workshop."

"Now is the time to recruit new miners."

"There must be a spy in there."

“So, after you recruit these miners, you have to be mentally prepared.”

Zheng Zhiqian nodded: "Yes, Lao Wang and I have discussed this."

"Now, the miners we recruit are just miners, and we won't let them have any contact with the smelting workshop."

"As for the transportation of ore, we will also have specially arranged reliable people to do it."

Zhao Hao nodded slightly and said, "It's good that you two have come up with a plan."

After the plan was made, Zhao Hao personally supervised it and began to upgrade and transform the smelting technique.

The entire workshop was gradually divided into two parts.

The innermost part was directly turned by Zhao Hao into a forbidden area.

A month later, a large black pipe was cast.

Zhao Hao looked over and couldn't help but shook his head. He then asked someone to remake the mold and send it back to the furnace to refine it again.

Another month passed, and the big black tube that satisfied Zhao Hao was finally successful.

Zhao Hao put the big black pipe on an iron cart.

Then, all the craftsmen were summoned together.

"Everyone has worked hard over the past two months."

"This is what I want. From now on, you will forge this kind of thing for me."

No one knows what Zhao Hao wants to do with this big black pipe.

However, they had to do whatever Zhao Hao said.

Wang Mengyu and Zheng Zhiqian came over and saw the big black pipe placed on the iron cart.

The two of them couldn't help but ask immediately.

Wang Mengyu walked around the iron frame car three times and asked, "Brother Hao, what do you do with this big thing?"

Zheng Zhiqian also cast an inquiring look.

Zhao Hao patted the big black tube and said with a smile: "This thing is a good treasure."

"You two might as well guess what this is used for?"

Wang Mengyu said, "There is no clue at all, how can we guess?"

As he said this, he turned and looked at Zheng Zhiqian standing beside him.

"Old Zheng, you're smarter than me, guess it!"

Zheng Zhiqian smiled bitterly and said, "You think too highly of me. We have never seen anything like this before, and I can't guess it!"

Wang Mengyu looked at Zhao Hao and said, "Brother Hao, just tell me what this is for!"

"I even made a special frame for it."

Zhao Hao smiled and said, "Forget it if you can't guess it. You will have a chance to find out!"

"Remember, this is top secret, no one can tell."

Wang Mengyu said, "That's it. It's useless to say anything. Old Zheng and I saw it with our own eyes, but we don't know what it is."

Zhao Hao said seriously: "Old Wang, I'm not kidding, this thing is top secret!"

Seeing his serious expression, Wang Mengyu smiled awkwardly: "Brother Hao, don't worry, I know!"

Zhao Hao looked at Zheng Zhiqian who was standing beside him again: "Old Zheng, you must always remind Old Wang about this matter."

"He is a careless person. He might have said it subconsciously at some point."

"Keep an eye on him at all times."

Zheng Zhiqian nodded seriously: "I understand, Brother Hao!"
