Wuhou came back from outside. This time he was in the kiln outside, which completely intensified the contradiction between himself and the Minister of war.

The old Marquis was worried that after the people of the great prince's faction took control of the kiln, they would secretly arm their own army to rebel, so he would rather be wronged than hand over the management of the kiln.

Tian Yuqiao also heard a little. It was because the steel-making kiln needed to burn a lot of firewood and charcoal every day. The price of charcoal has always been very expensive and can't afford to burn at all. In addition, the nearby wood can no longer meet the demand of the kiln, so the price of wood near the Imperial City soared.

This is an opportunity for Tian Yuqiao, so she plans to take the opportunity to sell her coal. At the thought of such a large kiln, which may also annex supporting buildings such as blacksmith's furnace, Tian Yuqiao felt that his coal seemed to be specially supplied to Wuhou.

When Tian Yuqiao said she had an idea, marquis Wu didn't believe it at first. It's all because she's a little girl talking about children, but she doesn't take it seriously.

Gongsun Yu finally opened his mouth and said, "Hou ye, miss qiao'er is not an ordinary person. She can always come up with some strange ideas. This time, she also helped Yaowang villa. Now I invited her home to help see our food."

"Oh? Making iron and steel is different from farming. If you know how to farm, you may not know how to make steel." although Marquis Wu still doesn't believe it, he is also moved.

"Dad, miss qiao'er is really different ~" Shangguan Qingfeng said.

He still has a fresh memory of the scene that day. As soon as the little girl raised her hand, she directly blew people's heads. Then she could sit next to the body and eat watermelon like a person who had nothing to do. Look at the brain flowing all over the place. She can eat it. Can ordinary people do it?

However, he didn't mention these terrible scenes to his parents for fear of frightening the old lady.

When his eldest son speaks, marquis Wu will still consider it. After all, Shangguan Qingfeng was never a crazy talker, so Marquis Wu looked at Tian Yuqiao again.

Nodded and said, "well, how about going into the study with Ben Hou?"

Tian Yuqiao nodded and said, "well, after all, this is a secret, and I don't want to be known by too many people."

Gongsun Yu stamped his feet angrily and said in his heart that you treat us all as outsiders. Thanks to me, I spoke for you just now.

But he also thought of what Tian Yuqiao was going to say. After all, he had placed a large order with Tian Yuqiao. At ordinary times, the fire at home and the coal to be used in the farm were ordered from Tian Yuqiao.

The old Marquis led Tian Yuqiao to the study. When Shangguan Qingfeng saw that they had left, he grabbed Gongsun Yu's arm and asked, "tell me, do you know anything?"

Gongsun Yu said proudly, "I'm not sure yet, but I'm almost there. It's estimated that the problem of your father's kiln factory should be solved soon, but you should also make some sacrifices. If it's not guaranteed at that time, you have to be like my family. You have to be prepared."

Shangguan Qingfeng looked suspicious, but seeing Gongsun Yu's gloating appearance, his heart began to beat drums.

In the study, marquis Wu and Tian Yuqiao sat opposite each other. After looking at each other for a long time, marquis Wu smiled and said, "well, you little girl really have a bit of courage. Ordinary children are afraid of me. It is said that I kill too many people. Unexpectedly, you are not afraid of me and dare to look at me."

Tian Yuqiao said with a smile, "I don't think you have anything, but I think you are very kind."

"I'm... Very kind? You're really interesting, little girl. Come on, let's get down to business. You just said you had an idea. I'd like to hear what you can do to let me reduce the cost of the kiln."

Tian Yuqiao thought about it before he said, "well, we have a very fire-resistant thing that can make the fire last for a long time. It's called coal. If you all use this kind of thing, you don't have to burn so much wood. I simply calculated that a kilogram of coal can almost hold a large bundle of firewood. How about it?"

"Oh? Is there really such a magical thing? You don't mean charcoal? It's very expensive. It's only used to make a fire pot in the house when it's cold in winter."

Tian Yuqiao shook his head and said, "it's not charcoal, it's coal. Coal can burn longer than charcoal, so the price is higher than charcoal."

"You little girl, are you waiting for me here? But no matter what you say, I have to see something, don't I?"

"That's natural. We're in business. I must show you the goods. How about this? A batch of such coal will be sent to King Jing's residence in a while. You can ask the Shizi to send some to you."

"Well, it's a deal. Alas, you're a girl. If you're a boy, I have to buy you two drinks today." Marquis Wu was a little depressed, but now he's much better.

"Hou ye, we have disturbed you and me for too long today. It's time to go back."

"No wonder my wife likes you so much. You little girl really has a way. Alas, I had a daughter back then. It's a pity. Don't say it. Look at me. I'm almost infected by my wife."

After they went out of the study, they found Shangguan Qingfeng and Gongsun Yu standing at the door like door gods.

"You two smelly boys dare to eavesdrop."

"Dad, your mood seems to be much better."

"Lord Hou, I'll tell you. Qiao'er is a clever and sensible girl. I'm much more comfortable to have her with me today."

Wuhou took his wife's arm and said to Gongsun Yu with a smile, "Xiaoyu, remember to bring it to your father and mother when you get home. Take Qiao Er to our house when you are free and let her chat with your aunt."

Although Gongsun Yu was helpless, he still nodded and said, "OK, if I can do it, I will try my best."

Tian Yuqiao secretly kicked him. Then he said with a smile, "thank you for your hospitality this time. We ate well and had a good time."

"Girl Joe, don't forget what we said in the study. I'll wait for your good news."

Tian Yuqiao made an "OK" gesture and said, "Lord Hou, please rest assured. Anyway, even if I run, Gongsun can't run. Just find him at that time."
