Cao Cao just groaned slightly, and then said,

"Taking the manufacture of rib and angle bows as an example, if you want to create a qualified rib and angle bow, after the materials are ready, you need to lay the ribs and laminate the bow body to ensure the close combination of the bow tire, the rib angle and the bow tip."

"In addition to that, the bow body needs to be baked."

"After the bow body is formed, it is still necessary to train the bow like an animal, and slowly hone the adaptability of the new bow to various tensile forces to produce deformation."

"When the training is complete, you can paint the bow."

"Not only as a decoration, but also to prevent the ingress of moist air and prolong the life of the bow."

Cao Cao is worthy of being a military master, and he is also familiar with the manufacture of bows and arrows.

"The lord is really knowledgeable."

Guo Jia on the side praised and added,

"If you are a skilled craftsman, it will take three months at the earliest, and this is still when the materials are ready."

Listening to their words, Yang Ling smiled,

"According to what the lord said to Mr. Fengxiao, if you build a crossbow arrow, I'm afraid you won't be able to get it in four or five months, right?"

Cao Cao and Guo Jia both nodded.

Compared to bows and arrows, crossbows are more complicated to make.

"What if the entire manufacturing process was divided into different steps, with the craftsman taking care of it in batches?"

Yang Ling asked with a smile.

As soon as these words came out, several people in the study were stunned.

"What do you mean, sir?"

Cao Cao frowned, a little bit unable to understand Yang Ling's words.

"Bows and crossbows take a long time to make, partly because of the trouble they make, and partly because there are no qualified craftsmen."

"Or take the rib bow as an example, we can divide the manufacturing process into four steps: lamination, baking, bow training, and painting."

"We can recruit a large number of people and have them each responsible for one of the steps."

"In this way, the manufacturing efficiency can be greatly accelerated!"

Yang Ling talked eloquently and explained the so-called assembly line operation to everyone.

Except for Dian Wei, the other three people in the study were extremely intelligent.

Hearing Yang Ling say this, they understood what assembly operation was!

Compared with the traditional training of craftsmen, this method can instantly train a large number of skilled craftsmen, and has extremely high production efficiency!

"What a ghost, sir! You can come up with such a way! ”

Cao Cao couldn't help but be amazed.

Cao Ang's gaze towards Yang Ling was full of admiration, the teacher was really smart!

Even Guo Jia, who has always been arrogant, has to admit that the gap between himself and Yang Ling is ...... It seems to be getting bigger!

"Fengxiao, let's start preparing according to the assembly line operation method that Mr. said."

Cao Cao immediately made a decision and decided to manufacture the Lingyue Repeater in large quantities to prepare for the army.

After Guo Jia received the order and left, Cao Cao was full of emotion,

"Sir not only took out a big killing weapon like the Ling Yue Repeater, but also came up with a brilliant idea like an assembly line operation. How will you let me reward you? ”

Yang Ling thought about it and said,

"Back to the lord, my subordinates really have one thing to ask for."

Cao Cao was a little surprised, but he didn't expect that Yang Ling, who didn't seek fame and fortune on weekdays, would take the initiative to speak.

He was stunned for a moment, then laughed and said,

"Sir, even if you open your mouth, don't say one thing, even eight out of ten, and it's not a problem."

"That's the case, I don't know what the lord plans to do with Zhang Xiu?"

Yang Ling arched his hand,

"If it's possible, I hope the lord will spare his life."

As the saying goes, you have to listen to the wind next to your pillow if you don't listen.

Since following Yang Ling, Zou Rui has been extremely well-behaved on weekdays.

On the bed, he was even more obedient to him.

Whenever Yang Ling spoke, she obeyed any tricks and postures.

Just two nights ago, after the two were happy, Zou Rui cautiously proposed that she hoped that Yang Ling could help her nephew Zhang Xiu and intercede with Cao Cao.

Yang Ling is not a person who doesn't recognize people when he puts on his pants, so he finally agreed.

"It seems that Mrs. Zou is a national beauty, otherwise Mr. would not have interceded for Zhang Xiu."

Cao Cao smiled and quipped,

"Since the gentleman has spoken, how can I not agree to a trivial matter? Don't worry, I won't kill him, I'll use him. ”

"Thank you, my lord!"

Yang Ling arched his hand happily.

After a few more small talks, Yang Ling got up and retired.

Watching his background disappear outside the door, Cao Ang couldn't help but sigh to Cao Cao,

"Father, the teacher is really a person who values feelings."

"It's true."

Cao Cao paused, followed with a straight face,

"Do you know that this trip to Wancheng is wrong?"

"Back to my father, I know it's wrong, I shouldn't have forcibly dedicated Zhang Xiu's aunt to the teacher."

Cao Ang sincerely apologized and admitted his mistake.

"Looks like you still don't realize what you're doing wrong."

Cao Cao sighed.

Looking at his son's blank expression, he hated iron but not steel,

"Yang Ling not only likes beautiful women, but also women. You are naturally doing the right thing to dedicate Mrs. Zou to him. ”

"But your mistake was that you were too careless, you didn't take away the military power in Zhang Xiu's hands, and gave him a chance to rebel!"

Cao Ang was dumbfounded.

Listening to his father's meaning, he didn't object to giving Yang Ling a beautiful woman?

"Do you know that as a father, why did you let Yang Ling be your teacher?"

Cao Ang thought about it and said cautiously,

"Is it because the teacher is shrewd and resourceful?"

"Yes, but not quite."

Cao Cao said this, making Cao Ang a little confused.

"Yang Ling is extremely talented, full of wisdom and good at planning. By making him your teacher, you want you to learn from His strengths, and that's one thing. ”

"Second, although he did not hold any important positions, Dian Wei, Xu Chu and others all had a good relationship with him."

"If your father dies in the future, with him to help you, the foundation of our Cao family will not collapse!"

Cao Cao said in a deep voice.

Cao Ang suddenly realized.

Yes, as my father said.

Although the teacher Yang Ling is only a small grain transportation officer, his network is extremely wide.

Cao Cao's two personal bodyguards, Dian Wei and Xu Chu, were his sworn brothers.

Another sworn brother, Zhao Yun, has a low official position, but he is extremely brave.

He has a life-saving grace against Gao Shun, the general of the trapped camp!

Huang Zhong, Gan Ning and Zhang Ji, who have recently defected to him and have been reused, also have a lot to do with him.

In addition, Mi Zhen, the only woman in the Xuzhou wealthy merchant Mi family, is a woman from Yang Ling.

Yang Ling also runs the business of perfume and Moutai, which is not an exaggeration to describe it as a daily gold fight.

If anything happens to Cao Cao in the future, Cao Ang will definitely be able to stabilize the situation with the help of the Cao clan, plus Yang Ling!

"Father is really far-sighted!"

Only then did Cao Ang understand his father's good intentions!

"It's best if you know what a father thinks like."

Cao Cao patted Cao Ang's shoulder with relief, and then said with a solemn face,

"But you also have to remember that if Yang Ling has any bad intentions, he will definitely kill him by thunder!"
