Ma Du couldn't wait to spit out a mouthful of old blood, according to the current cost, Lao Zhu would definitely bear it, but the productivity was there, and just making this cannon would break Ma Du.

Although it is said that with one experience, the later ones will be much better, but after all, it is five hundred. Ma Du said that Lao Zhu agreed to wait for the performance test of this cannon to be completed before deciding whether to mass produce it.

At the same time, Ma Du recommended Jiao Yu, who was the director of the workshop in Zhongshu Province, to serve as the deputy supervisor of the Firearms Bureau, who was responsible for the production of firearms, and he Ma was responsible for the development of firearms.

Lao Zhu was very embarrassed, and he agreed, so everyone was happy, especially Jiao Yu. The Firearms Bureau was a small yamen when he heard it, but Lao Zhu attached great importance to it, and forcibly promoted the chief officer to the fourth grade.

Zhao Desheng, who has been recuperating in the Firearms Bureau, was also rewarded, Lao Zhu rewarded him with a lot of gold, silver and cloth, and his promotion did not make much sense, even if he gave him 100,000 troops, he couldn't bring it.

From that day when he happily had a birthday party at home, Mado's days almost never stopped. Cannons, cannons are fired every day, but the sound is not the snap that Ma Du expects, but boom boom.

In order to obtain the performance data of the artillery, with these detailed data, it is good to formulate specifications for training soldiers. It's always bad to hit too many guns, and it is inevitable that there will be some sequelae, and this sequelae is the same as the sequelae caused by the "gunner", tinnitus, kidney deficiency will cause tinnitus.

It's just that Ma Dajia has been looking for a target for Ma Du, Ma Du was still very interested at first, and he also participated in it with great interest, Ma Du knew that his marriage must not be able to bypass her.

However, he was soon disappointed, and Ma Dajia looked for him for nothing more than the following characteristics: small feet, a face like a silver plate, short and thin, large breasts, and fat buttocks......

If you can have three of these characteristics, plus you are good at female celebrity or literary ink, you will be recommended to Ma Du by Ma Dajia, of course Ma Du doesn't like it, and just begs Ma Dajia not to hastily engage him.

When the barrel of the cannon cracked with a gray-white fracture, Mado wrote a number on the paper in one breath. The first gun, after firing 180 shells, was finally scrapped, and it was still under the condition that Madu continued to increase the amount of ammunition.

This number is actually beyond Madu's expectations, if the artillery behind can have this cannon in the case of a fixed charge, Madu will be content.

He searched his intestines and scraped his stomach, and used his little artillery knowledge to formulate a series of norms and training plans and handed them to Lao Zhu. Seeing that Lao Zhu was very satisfied, Ma Du took the opportunity to persuade Lao Zhu to reduce the number of artillery, and Lao Zhu readily agreed, and only let the Firearms Bureau make half of the 250 guns.

Such artillery is an artifact in the eyes of Lao Zhu Xuda, and it is scum in Ma Du, and sooner or later it will be replaced by more advanced artillery, and doing more will only waste financial resources.

Jiao Yu took care of the affairs of the Firearms Bureau, and Ma Du stole half a day of leisure, traveled through six hundred years, and finally fulfilled his original dream, a teacher.

The school has always been managed by Yuan Jiuli, he also serves as the principal, teacher, janitor, cook, handyman and janitor, although this person is quite stubborn, but I have to say that he is a good teacher.

He has always completed his work according to Ma Du's instructions, such as preparing classes in advance and handing them over to Ma Du for review, educating the little turtle in an encouraging way, and he even accepted male and female students to attend classes in the same room.

But why add a curtain in the middle, or a curtain that Yuan Jiuli pulled out of his own pocket. On one side are boys, and on the other side are girls.

Although it was only through a thin curtain of cloth, the other side could be heard when taking a breath, but the boys and girls on both sides never spoke, and they did not go in and out of the same door, it was strange like two worlds.

Even the most naughty little fish and water chestnut never dared to open the curtain and talk to the little turtle brother, because Mr. Yuan's board was very painful to beat people.

Ma Du wanted to tear the curtain off, but when his hand touched the curtain, he couldn't help but think of Liu Ji's words, so he let go of his hand. That's right, he's just one person, and he can't stand up to the whole world.

Under Yuan Jiuli's careful teaching, these children already knew a lot of simple words, and Ma Du immediately ran over to pick peaches, so the students had another arithmetic class.

Ma Du found two students who were very talented in mathematics, one was a small turtle, but in fact, this was not Ma Du's accident. Although the little turtle is not good at talking and stammering, he has no problems with his brain, on the contrary, he is very smart, his memory, logical thinking ability and imagination are very strong, and there is no problem in learning mathematics well.

The other was the child who came to their class almost every day by lying outside the window, but as soon as Madu spoke to him, he immediately ran away.

Finally intercepted him once, only to find out that this was a skinny boy with a small head, and when he saw that he couldn't break free from Ma Du's hand, he begged for mercy and said that he would never dare to come to the class again, and begged Ma Du to let him go.

It turned out that he came to listen to the class, Ma Du casually gave him a few addition and subtraction, no matter how many numbers Ma Du reported mixed addition and subtraction words, he blurted out that mental arithmetic is very fast, and asked him if the multiplication and division law is not, because Ma Du has not taught it yet.

is so studious and so smart, Ma Du thought he would be a well-known celebrity, but who knew that he patted his thin little body and said that it was called Lin Daniu, and he was also a tenant of his own family.

It's just that why don't you come to the house to take classes, and you don't have to pay for the tuition, and you still take care of a meal. Lin Daniu said with red eyes, "My mother and people, I ran away with other men, my father said that the school would not accept such a person, and Mr. Yuan didn't come to call me." ”

Taking advantage of Ma Du's stunned moment, the child broke free of Ma Du's hand and ran away without a trace. Ma Du directly found Yuan Jiuli and asked him to inform Lin Daniu to come to the school to take classes, but Yuan Jiuli was unhappy.

Ma Du said: "I know what you want to say, but it was his mother who made the mistake, what does it have to do with him, don't you talk about Ziyue all day long, I don't remember what Kong Sheng said, there is no class but he said it." ”

Yuan Jiuli said: "Accepting such a person into the hall is really insulting to the lintel of the saint, and it is also detrimental to your reputation." ”

Ma Du smiled, "How did I damage my reputation, I didn't have a relationship with Lin Daniu's mother." He suddenly lowered his voice and said, "Have you forgotten how Kong Sheng's old man came to this world?" ”

Yuan Jiuli's face immediately flushed, and he said excitedly: "That's slander!" That's the villain's slander against Kong Sheng! ”

"Hahaha...... So you've heard about it too! Ma Du laughed, he didn't expect that after more than 600 years, there would be such rumors, which may not be groundless!

"I don't care, call Lin Daniu over to class together, if you don't go, I'll find another gentleman!" I don't know why Ma Du just likes to scare him and watch him jump like thunder.

"Sooner or later, I'm going to leave this rotten place where there is no sense of right and wrong!" Yuan Jiuli's unwilling roar came from behind him.
