Ma Du somewhat understood why the medical craftsmen in the army were called lowly servants, except for the gynecological holy hand who was stuffed in yesterday, the others were all in rags, not much better than the beggars on the street, and they were full of rotten smell and did not know how many days they had not taken a bath.

When he entered the ward, Madu was even more disgusted, he didn't dare to expect how clean the ward here was, but as soon as he entered the room, the smell of stench directly smoked him backwards.

In several open rooms, there were many bed boards placed horizontally and vertically, dry poop could be seen in almost every corner, and there were traces of water washing on every wall, and the stench smell gave Mado enough reason to believe that it was not rain.

In the empty ward, Ma Du was lucky to find a wounded soldier, a wounded soldier who had undergone amputation, which made Ma Du couldn't help but be surprised, he didn't expect those ragged doctors to complete such an operation in such an environment.

After a brief exchange with the wounded soldier, Mado's surprise immediately turned to anger. It turned out that this man was actually just a guy in the army, because he accidentally cut his finger while chopping vegetables.

After being treated by the medical craftsmen of the wounded barracks, he became inflamed and suppurated and had to cut off his fingers. This did not make his injuries better, but he lost his palms and arms one after another, but fortunately this time his wounds finally began to heal, and he did not lose his life.

Madu was amazed at the man's tenacious vitality, lamented his misfortune, and patted him on the shoulder as a sign of comfort. The man was not sad, and said that the groom who lived with him in the wounded barracks had burped after sawing off his thigh because he had stepped on a nail, and he was lucky to be able to save his life.

Harming people like this can also make people feel grateful, and Madu has never seen it before. He asked everyone about it, and then he realized that although these individuals in front of him had the name of a healer, they had no ability to cure diseases and save people, and most of them had used hoes to dig in the ground. The only one who can be related to the knife is a butcher, and it is said that he can take the arrow twice, but judging by his gestures, Madu does not feel like saving people, but like killing pigs.

It's just that you don't have the ability to save people, but you are embarrassed to accept several apprentices, do you want to learn to kill people from you?

It is estimated that Zhu Wenzheng did not count on them, it turned out that once they encountered a bloody battle, they would recruit local doctors and Langzhong, and these medical craftsmen and apprentices would be reduced to a share.

There were no wounded soldiers in the wounded barracks in peacetime, and they were usually either wounded and left the camp within a month after the battle, or they died. After the dismissal of the doctors and Lang Zhong who came from the expedition, this place does not have the function of curing diseases and saving people at all, and it is not too much to say that it is the palace of the king of Hades.

On weekdays, soldiers have a headache and brain fever, and would rather spend money to find a hospital on the street than come here, like the horseman and the gangster, who do not know the situation, and there are definitely a few who come to die recklessly.

The situation in the injury camp made Mado a big mess, and it was definitely a mess...... No, it's a rotten sieve. The only thing I am glad for is that it is not too difficult to draw on a blank piece of paper. Chen Youliang is coming soon, and at this time, he needs to take drastic and resolute measures, take out the regulations of the injury and sick camp formulated last night, and let them do it.

For Ma Du's work, Zhu Wenzheng gave a lot of support. not only gave him a hundred auxiliary soldiers and a lot of money, food and materials, but also gave him the title of the governor of the capital, in order to facilitate his actions, Ma Du had no choice but to accept it, anyway, he would not make any bullshit military orders.

I don't know how big an official this is, anyway, the entire wounded barracks is under his control, uh...... It seems that there is nothing to be proud of. After arranging all the matters, he handed it over to the gynecological holy hand to lead people to do it, because among more than a hundred people, only this one is literate.

As soon as the arrangement was completed, Zhu Wenying invited him to the school field. Last night, he asked Zhu Wenzheng to lead an army alone and be responsible for defending a city gate. Zhu Wenzheng did not agree, and only asked him to follow Deng Yu's side, which Zhu Wenying was very dissatisfied.

"You say why can't I guard a city gate alone, I have been in the army for a long time, and I haven't read less military books, Brother Donkey just looks down on people and treats me as a child."

"Alright, alright. The Metropolitan Governor has his own reasons for arranging this, this is a battle of life and death, and don't always call him by his nickname, especially in front of the generals, if he is unhappy, he really dares to beat your military stick. ”

Nouveau riche hate others mentioning the unbearable past the most, and proud people like Zhu Wenzheng are afraid that the same.

"Hehe, you know him better, he didn't clean up Brother Bao'er and me in the past. Isn't it just a nickname, Brother Bao'er doesn't care, I don't care, my nickname is Zhou She, what about you, call it a dog or a plug? ”

You are called a dog, and your whole family is called a dog! glared at Zhu Wenying fiercely, and when he saw the evil smile on the corner of his mouth, he knew that this guy was doing it on purpose.

"My nickname is Xiaodu, and that's what my grandfather calls me."

"Xiaodu, it's really better." Zhu Wenying suddenly lowered her voice, "Didn't your grandfather also go to Yingtian, did he go to the Guogong Mansion to see my father, did he see the emperor's qi in my father?" ”

Ma Du shook his head, "I didn't go to the Wu Guogong Mansion!" We left on the same day we passed by Yingtian! "I didn't expect to make up my own nonsense, this guy is so attentive, even if he has it, he doesn't dare to tell you, who made your godfather so stingy and hold a grudge.

"You really didn't go?"

"Nope!"

"This can be had, my father won't mind!"

"Not really!"

…………

followed Zhu Wenying to a wide school field, and there were only Deng Yu and a few soldiers in the huge school field.

The four soldiers were handling a strange thing, a copper tubular object the size of a teacup.

The thing was just over a foot long, and near its tail it had become a bulge in the shape of a ball, into which two soldiers were pouring gunpowder, compacting it with a strip and stuffing it into an iron ball slightly larger than the yolk, and then inserting a twist into the bulge.

It is fixed with a special wooden stick, and two people carry the two ends of the stick, and the other person holds a torch to the side.

Ma Du muttered curiously, "Is this a mouthpiece?" He often traveled with his grandfather, and the places he frequented were neither magnificent ancient cultural buildings nor beautiful and magnificent mountains and rivers. The most visited are the old red area and various military museums in ancient and modern China and abroad. He was still a little impressed by the strange firearm in front of him.

Deng Yu turned around, "Mr. Xiao is here, do you also recognize this artifact in the army?" ”

Ma Du really recognizes it, I'm afraid he doesn't deserve the title of artifact. Could it be that those majestic cannons on costume TV are all deceptive, and this little thing that is just a foot long and an arm is the most powerful firearm in the world?

"The gunpowder formula given by Mr. Xiao yesterday has just been configured and is preparing to test, please give me some advice."

Yesterday, in order to enhance Zhu Wenzheng's confidence in defending the city, Ma Du selflessly offered the best prescription for black powder. Coincidentally, Deng Yue mastered the most powerful firearms unit under Zhu Yuanzhang, and in later words, Deng Yue could be regarded as the commander-in-chief of the Second Artillery.

Ma Du gave up his hand, "Don't dare to be, please participate in politics and light the fire, let me see." ”

As soon as Deng Yu waved his hand, a person lit the medicine twist with a torch and sneered...... Boom! With a loud bang, a burst of fire erupted from the mouth of the gun, and a black shadow shot out, and then a small puff of smoke and dust rose from the ground one hundred and fifty meters away.

"Good!" Deng Yue clenched his fists fiercely.

Zhu Wenying was surprised: "Haha...... It's almost a hundred steps! Your gunpowder recipe is amazing. ”

While laughing, he slapped Madu on the shoulder, and this bastard laughed at Madu's ugly writing when he saw the gunpowder formula yesterday.

The unseen dirt buns, if they make a big fart movement, they will be happy like this, and if they see the rain of fire caused by the military exercises of later generations, they will not go crazy.

Deng Yu bowed his hand, "With the new formula given by Mr. Xiao, Deng Mou's confidence is a little more, thank you here." ”

Ma Du hurriedly returned the salute, "A little thing is not enough to worry about." If you want to increase the range and power, the gunpowder recipe is important, but there are many more effective methods, such as increasing the amount of gunpowder or increasing the length of the gunner. ”

Deng Yu nodded, "Increasing the amount of medicine can indeed increase the range, but this point is not easy to grasp, and it is easy to blow up if you are not careful." What is the reason for increasing the length of the tube? ”

Ma Du pondered for a moment before saying, "Does Deng Shenzheng know how the projectile flew out?" ”

Deng Yu replied: "Of course, the medicinal power is urging the burst out, isn't it?" ”

Ma Du replied: "What Deng said is right, but the details of the process are missing. When the gunpowder explodes, it produces a large amount of gas, and the projectile is pushed out by these gases......"

"Qi can also be so powerful? Can you send the iron bullet so far," Zhu Wenying asked incredulously.

"You can send phlegm far in one breath, so what's so strange that the gas from the explosion of gunpowder can send iron bullets out?" Ma Du looked at Deng Yue and continued to explain, "This pushing force will disappear as the projectile leaves the gun, so the longer the gun, the greater the pushing force, the longer the range, and the greater the power." Of course, you can't make the gun tube too long, which will increase the friction between the projectile and the gun tube, which is too much. ”

Zhu Wenying stared at the big eyes and looked dazed and ignorant, Deng Yu was obviously very knowledgeable about firearms, and nodded frequently when he listened, "What size does Mr. Xiao think is the best size?" ”

"It's better to shrink the caliber a little, at most three feet long." Mado simply asked for a pen and paper to draw a pattern.

Ma Du is not a fool, he painted a copper fire gun in the Yongle period, in addition to reducing the caliber and increasing the length, the ignition hole in the medicine room also added a sealed fire door. In this way, you can load the ammunition in advance, and you can ignite and fire at any time without worrying about the gunpowder spilling during the march.

Deng Yu took the pattern and looked at it, "I'll find a craftsman to do it!" ”

"Deng will participate in politics for a while." Ma Du drew another pattern and handed it to Deng Yu with a smile, "This is the original purpose of my gunpowder formula." ”

This time Zhu Wenying understood, "Isn't this a big firecracker?" ”
