After Yan Rui was sent over, Diao Chan and Zhang Ning felt a little savory.

However, they also knew that Yan Rui was Yan Baihu's niece, and the reason why Yan Baihu surrendered to her husband was closely related to her.

Political marriage is a very normal thing in this era, and they have long been used to it.

And their identities are just concubines, not even their wife...

So Diao Chan and Zhang Ning were very friendly to Yan Rui, and soon the three girls became good friends who could talk about everything. When fighting against Landlords again, there was no need to pull the little girl on the stage.

After the mountains and rivers were settled, Lu Bu held a banquet for Yan Baihu.

This wine is a must-have for both public and private.

After three rounds of wine and five dishes, Yan Baihu said to Lu Bu: "I heard that the lord is getting more and more worried about the mountains of Kuaiji County?"

Lu Bu nodded and said, "Yes, these mountains and rivers are built on the mountain, which are easy to defend but difficult to attack. If you attack strongly, you will suffer too many casualties. Besides, they are just civilians, not unforgivable enemies. It would be great if they could be educated by the court."

Yan Baihu said to Lu Bu: "Lord, it would be fine if it was a mountain peak elsewhere. The mountain peaks in Kuaiji County are all known to me. If the lord does not abandon it, I can try to convince those mountain peaks, but to place them..."

After hearing Yan Baihu's words, Lu Bu couldn't help but be overjoyed. Now he was getting more and more worried about the mountains in Kuaiji County. If he could be recruited successfully, it would be a great thing.

Lu Bu hurriedly said, "Don't worry, their placement will be the same as yours! I believe you have also seen that there are a large number of people in Shanghai County at present, and the more people come, the better. Don't be afraid of not being able to place it."

Yan Baihu nodded and said, "If this is the case, I can go lobbying them with confidence, but I cannot guarantee that I will succeed."

Lu Bu said happily: "This kind of thing can only be done to leave people to fate. There is no guarantee that success is guaranteed. Don't worry, whether it succeeds or not, your contribution will definitely not be eliminated."

Yan Baihu nodded and said, "I feel relieved when my lord said this. Then I will take a trip to Kuaiji County tomorrow."

Lu Bu nodded and asked Yan Baihu to go to Kuaiji County to find Jia Xu first, and listen to Jia Xu's arrangements for all actions.

After solving this problem, Xun You came to Lu Bu to report on his work.

Xun Yu is not in Shanghai County at present, so Xun You comes to take the shift for the time being.

Xun You was secretly shocked about the development model and development speed of Shanghai County.

This development speed is really too fast, it is changing with each passing day.

Xun You came here to report on the work. It turned out that the cement had been successfully fired, and the steel mill also refined steel. After inspection, it was completely at the level of 100 steel making.

Great! The steel mill successfully refined steel, and after Huang Chengyan's improvement, the steel produced can directly reach the quality of hundreds of steelmaking on the market.

Such steel can be used directly to cast weapons.

You know, at this time, it is not only time-consuming and labor-intensive to create a weapon that can make a powerful weapon.

For ordinary troops, only generals and small leaders can use the weapons of steelmaking.

As for ordinary soldiers, they all use very rough iron tools.

On the battlefield, this kind of iron weapon may be curled if it is less than three or five people.

Sometimes, if you stab in with one knife, the knife will be bent and deformed, and you need to put it on the ground and step it straight before you can continue to use it.

But on the battlefield, who will give you time to organize your weapons first?

However, the steelmaking technology has been greatly improved now. As long as the steelmaking output is increased, the weapons of steelmaking can be popularized throughout the army.

In this way, the combat effectiveness of the entire army can be greatly improved.

However, if it is made by hand, although the time to build a weapon is greatly reduced, it still takes too long.

If you want to reach popularity throughout the army, it may not be possible in five years.

If there is a mold, this time can be greatly reduced.

There are special molds, so that the steel juice can be poured directly into it, and after cooling, the molded weapon can be obtained.

As long as there are enough molds, the production efficiency will be improved by hundreds or thousands of times.

...

When Lu Bu came to the steel plant, he found Huang Yueying playing in the steel plant. When he saw Lu Bu, he came up from afar, and his eyebrows and eyes turned into crescent moons.

"Brother Lu, Dad ignored me and no one was playing with him. Can you come and play with him?"

Lu Bu touched Huang Yueying's hair affectionately and said, "Yueying, your father is obsessed with research, and I'm afraid he won't care about you. If you feel bored, go and play with your sister Chan'er and Sister Ning'er!"

Huang Yueying pouted and said, "Brother Lu, Sister Chan'er, Sister Ning'er and Sister Rui'er, and the new sister Rui'er. They always like to play Landlords, but they don't like it."

Lu Bu couldn't help but smile and said, "Then what do you like?"

Huang Yueying couldn't help but blinked and said to Lu Bu, "Brother Lu, I like you to give me natural science books. Otherwise, you can tell me a hundred thousand whys!"

Huo, okay, this girl has different thinking from normal children and likes to study very much.

Looking at Huang Yueying who was thirsty for knowledge, Lu Bu couldn't help but feel moved and remembered something.

Lu Bu couldn't help asking: "Yueying, are you interested in mathematics?"

Huang Yueying asked with her little head tilted, "Brother Lu, what is mathematics?"

Lu Bu couldn't help but explain to Huang Yueying: "Yueying, I'll ask you a question first. Put the chicken and rabbit in the same cage. If you count the heads, there are thirty-five heads. If you count the heads, there are 94 feet in total. Ask..."

As a result, before Lu Bu finished asking, he saw Huang Yueying saying disgustedly: "Brother Lu, this question is from Sun Zi's calculations, and he has read it a long time ago!"

This question actually comes from the calculation of the scriptures of Sun Tzu? Lu Bu really didn't know about it.

He saw this question in modern times and always thought that it was created by modern people.

Lu Bu said to Huang Yueying embarrassedly: "Yueying, why don't you do this? I'll give you another question, you can listen."

"There is a team that is one hundred feet long. This team is moving forward at the same speed. While the team is moving forward, the centurion walks forward from the tail of the team, and then turns back to the tail of the line. At this time, the team is just one hundred feet long. How much has the centurion gone up in total?"

Huang Yueying tilted her little head and said to Lu Bu, "Brother Lu, please wait and see."

Lu Bu nodded, trying to see if the little girl could solve this problem.

This question looks quite simple, but it is actually quite difficult, and it also involves the calculation of squared calculation. Lu Bu feels that this question will definitely stump this little girl.

After a while, Lu Bu saw Huang Yueying frowning and thinking hard, and at the same time he was writing calculations on the ground with a branch. He couldn't help but smile and went to find Huang Chengyan.
