Li Yu immediately became interested and said, "Sir, why not consider installing more gears!

"The pinion drives a slightly larger gear, and the slightly larger gear drives a larger gear, which is connected together, so that the resistance of the shaft can be greatly offset."

Ruchi's eyes lit up suddenly and he asked in surprise: "Your Highness understands the way of the mechanism?"

For ordinary people in ancient times, the principle of gear is of course difficult to understand, but Li Yu is a modern person and is naturally familiar with gears.

He smiled and said, "I can't tell you, I just know the basics."

"Your Highness is so humble."

Ruchi said: "I have considered what Your Highness said just now. First of all, wooden gears cannot withstand too strong force and are prone to damage."

Li Yu said: "Iron gears can be used."

Ruqi smiled bitterly and said, "It takes a lot of time to make an iron gear. Even if you only make one, it will probably take two or three days."

In this way, the cost of time is too high and the gain is not worth the loss.

Li Yu thought about it and nodded slowly.

Ruqi also said: "Secondly, the grass-roots people are not creating these mechanisms for killing people, but hope that someone can use self-guards in critical moments. Therefore, its range is short and its power is small, and it only needs to hurt people."

Li Yu suddenly realized.

He couldn't help but bow and said, "Mr. Lu's kindness!"

"Your Highness will destroy the grass people."

At this time, a little girl walked out of the wing room on one side. She was fourteen or five years old and was holding a cup of hot tea in her hand.

She walked timidly to Li Yu and whispered: "Please have tea with your highness!"

Li Yu looked at this little girl and lived a very similar life to Mrs. Lu, as if it was carved out of the same mold.

He nodded secretly, she should be the child of Mr. Lu and Mrs. Lu.

Fortunately, the president of the child did not follow Mr. Lu, but Mrs. Lu.

Luqi glanced at the little girl and introduced to Li Yu: "Your Highness, this is the little girl Qiyan."

He happily took the teacup and smiled, "Thank you Miss Lu."

He held the cup and was about to drink it, when Zhu Da coughed beside him and whispered: "Your Highness!"

"It's okay."

Li Yu waved his hand to Zhu Da and took a sip of tea.

Tea is not very good, but the skills of making tea are very good.

Li Yu had just taken a breath of tea, and Lu Qiyan suddenly knelt down in front of him and kowtowed forward.

Her sudden action shocked Li Yu and asked in surprise: "What is Miss Lu doing?"

Lu Qiyan choked and said, "Your Highness's life-saving grace!"

"Save life?"

Have we seen it before?

Mrs. Lu's eyes were also wet and red, and explained to Li Yu: "One of the women rescued by Your Highness in Baiyun Temple is the little girl Qiyan!"

Li Yu never dreamed that the little girl in front of him would be one of the women rescued by him.

At that time, the cave was too dark and Li Yu couldn't see it clearly. Moreover, the women were all disheveled and naked, so he had no nerve to stare at them and look carefully one by one.

Luqi said: "Your Highness is the savior of the little girl and the savior of my Lu family. However, the mechanism created by Caomin almost injured Your Highness. Caomin... deserves to die!"

As he spoke, he was about to kneel down again. Li Yu took the lead, held his arm around him and said, "Mr. Lu doesn't have to be disgusted. After all, Mr. Lu doesn't know that the escorts in the Weiyuan Escort Agency are all demons of Tianjidao."

Is the Weiyuan Escort Agency from Tianjidao?

Ruchi really doesn't know about this.

His face suddenly changed and he asked in a trembling voice: "Your Highness, Caomin heard that the Taoist priests in Baiyun Temple are... all demons of Tianji Tao?"

Li Yu nodded and said that he was right.

Ruqi's eyes were red and he said ruthlessly: "Caomin goes to Weiyuan Escort Agency to settle the score!"

The people of Tianjidao kidnapped their daughters and helped them create mechanisms. When they thought of this, Luqi was so angry that he felt like a knife.

Li Yu grabbed his sleeve and said in a calm tone: "Mr. Lu doesn't have to go find them."

"Your Highness..."

"The people from the Weiyuan Escort Agency have all been sentenced to death."

Ruqi was stunned for a moment, and then, like a deflated ball, patted his head hard and said ruthlessly: "I'm such a confused insect!"

Li Yu could understand Ruqi's mood. He hadn't told him the real purpose of Baiyunguan's captives, otherwise he could have dig the grave of the Weiyuan Escort Agency.

He said seriously: "Mr. Lu, I have a reluctant request."

"Your Highness is the benefactor of my Lu family! What is your order? Just arrange the people!"

Li Yu said: "I hope Mr. Lu can move to the capital!"

Ruqi was stunned and looked at Li Yu in confusion.

Li Yuhan smiled and said, "I admire Mr. Lu's mechanisms very much, and I hope Mr. Lu can create some mechanisms for me, but I don't know if Mr. Lu wants it or not."

With Ruchi's ability, if he really wants to serve others, he will be snatched from his head by many people.

I never waited until now, and I was still an idle person, and my life was very tight.

He was used to being free and casual, and did not want to be controlled by others, nor did he want to learn everything he had, be controlled by others, and became an accomplice of the murderer.

But now Li Yu is making such a request, which really makes him feel embarrassed.

Seeing Ruqi stammering and not speaking for a while, Li Yu immediately realized that he was making Ruqi embarrassed.

He said in a brisk tone: "It doesn't matter if Mr. Lu doesn't want to."

Ruchi hurriedly said, "Your Highness, the grass-roots..."

Before he finished speaking, Lu Qiyan walked to him, hugged his arm, and whispered: "Dad!"

When he spoke, his little eyes kept secretly glanced at Li Yu.

Mrs. Lu also felt that if her husband could serve a lord like Li Yu, it would be a good choice.

She walked to the other side of Luqi and whispered: "Your Highness is very kind to the Lu family, and your husband should not refuse Your Highness."

His wife and daughter stood on Li Yu's side all of a sudden, which made Luqi feel a little amused.

He took a deep breath, intervened and bowed to Li Yu, and said, "I am grateful to Your Highness for being aware of it. The people are not talented, and I am willing to serve your highness!"

Li Yu was overjoyed when he heard this.

The little girl was also full of joy, grabbed Mrs. Lu's hand, and said excitedly: "Mom, we can move to the capital!"

Compared with the bustling and lively capital, Fancheng is naturally not worth mentioning.

The primary school apprentice also smiled so hard that she couldn't close her mouth and said stammeringly: "The youngest... the youngest is willing to work hard on His Highness!"

Li Yu smiled up and said, "Okay! You can move to the capital with your master!"

"Thank you, Your Highness!"

The elementary apprentice knelt on the ground and kowtowed.

The matter of Fancheng came to an end. Baiyun Temple was handed over to the county government, county government, prefecture government and even the imperial court to deal with it. Li Yu took his people with him, left Fancheng, and returned to Shangjing.

When Li Yu left Beijing, no one saw him off. Now that he returned to Beijing, not only a large number of officials went out to greet him, but even the prince Li Ju and King Li Deng of Wei also came.
