"Cough, it happened that the shaft of the tricycle I bought was worn. I want to ask Mr. Qi what maintenance method he has."

"No maintenance fluid?"

I don't know what that is. She just said it.

"Well. In fact, what I want to say is that I found a new material a few days ago. I think it's very suitable for the shaft of this kind of car. I don't know if Mr. Qi is interested

Of course, this new material was not discovered by her. It was discovered in her house after Qi Yu married her.

At that time, this kind of material was very rare, and it was used for some kind of special thermal facilities for the imperial palace. As the empress dowager, she naturally had it in her house.

It is also because this material is only used for the royal family, so it is called "huangtieshi".

At that time, Qi Yu thought that it was very special, so he studied it and found that the properties of huangtieshi were very suitable for making bicycle shafts.

Unfortunately, the imperial iron stone is so rare that only the royal family can have the qualification to use it. Therefore, it is impossible to use it in mass production of tricycles and bicycles.

Later, after Qi Yu left, Fengqing found this kind of mineral in a remote mountain village. Unfortunately, the mineral was found, but the Si people were no longer there.

Later, Fengqing gave huangtieshi to those who took over Qiyu factory to study and put it into use. As a result, the function of the new product became stronger.

At this time, Qingqing put forward this, also in order to get close to Qiyu again.

Qi Yu naturally remembered that he had found this kind of material in his previous life, but there was so little iron stone that he had no other idea about it even if he came back.

Now Qingqing mentioned new materials, and he didn't expect to go up with huangtieshi.

"You've probably heard of this material. It's called huangtieshi. At present, it is only used for Royal thermal facilities, which is extremely precious. " Qingqing observes Qi Yu's expression.

Qi Yu was stunned. He couldn't help looking at Qingqing suspiciously. Qingqing also looked at him in his spare time.

As if burned by the clear eyes, Qi Yu dodged and looked to the other side.

He knew that Qingqing was the empress dowager, and she didn't pay attention to the things he studied and did on weekdays.

Now Qingqing has put forward the material of huangtie stone. Qi Yu's mind has changed a lot. Isn't Qingqing just like him?

……

"Mr. Qi?"

Qingqing saw that Qi Yu was immersed in his thoughts, and he couldn't help reminding him.

"Ah I'm just thinking, since it's a royal product, how did miss Qing know about it? " If you say that, I'm afraid Fengqing is going to be ready to confess her identity just like the previous life.

In a word, he will not be one of the harem of Qing Dynasty in his life. Qi Yu pinched the heads of the group secretly.

Qingqing gave him a sly smile, "mountain people have their own tricks!" She sold it.

Qi Yu was shaken by the smile and covered her heart, which was beating faster and faster.

"Since it's a royal product, I'm afraid there's no way to use it so much." Qi Yu made an uninterested appearance.

"If you are interested in it, I can make it widely used."

Qi Yu was surprised by these words. It was different from the previous life. It is said that Fengqing had never done such things as wearing skirts in her previous life.

Qingqing looks at Qi Yu with possessiveness in her eyes.

"It depends on whether childe Qi is willing or not. Promise me a request."

Qi Yu heard this, immediately stood up excitedly, "I don't want to!"

"I haven't said what my request is. Why is Mr. Qi so excited?"

“……” Qi Yu was a little tongue tied for a moment.

"I hope Mr. Qi can cooperate with me."
