Zhu Youzhen was not surprised, there is no such term in the world now, if they knew, it means that they are also the same as themselves, from a certain time in the later life. "The grenade is a metal casing with a wooden handle at the lower end, which is thrown out forcefully when used." Zhu Youzhen drew a simple drawing of a grenade on the drawing. "The metal shell is filled with gunpowder, and the outside is connected to a pull rope, and at the other end of the pull rope is a special friction line, like a fire breaker, pulling the pull rope hard, generating sparks and igniting gunpowder." Zhu Youzhen explained for a long time, these craftsmen are still confused, there is no way, not everyone can understand advanced weapons, and even if they do, they may not be able to make them.

"I see, when you pull the drawstring, it's like rubbing a fire breaker and igniting the gunpowder inside." Finally, a middle-aged craftsman realized, "There is a fire fold on the drawstring, and there should also be a fire fold in the grenade." ”

"That's the way it is." Zhu Youzhen was relieved, "These two fire folds must be fixed, otherwise, once they are displaced, they will automatically explode." "As for what materials are used to ignite, it is the business of the craftsmen, after all, Zhu Youzhen is not an expert in making ammunition, he just uses the experience of later generations to point out the direction for these craftsmen.

The principle of a mine is similar to that of a grenade, except that the pull cord is changed to a metal rod, because the mine is buried in the ground, and the metal rod is stepped on by an external force to trigger the detonating device.

Except for the middle-aged craftsman just now, the others still didn't seem to understand, and looking at their eyes, they all looked quite confused. This confusion quickly turns into jealousy.

Only then did Zhu Youzhen remember that the craftsmen of the Ming Dynasty were all independently developed, and the so-called church apprentices starved to death of the masters. Only when craftsmen have unique skills can they show their importance and increase their income, and those craftsmen who have mastered unique skills will generally only pass on their skills to their sons and grandchildren, and if they do not have sons, or if their sons change jobs to other jobs, they will pass on their skills to their apprentices, and generally when they are old and about to retire, they will pass on all the key skills. If the craftsman who mastered the technology died in an accident and lost the ability to teach, the technology would be lost, which was one of the reasons for the slow development of Daming technology. "You have to cooperate with each other, secrecy is only for outsiders, it is not needed within you, the manufacture of mine grenades is not done by one person, and time is also very important, beyond time, no one buys the mine grenades. If you can make a mine grenade, I will give a reward of 100 taels, and I will buy mine grenades on a large scale in the future. ”

"One hundred taels?" The craftsmen's eyes widened, and they looked at Liu Yifei again, worried that Zhu Youzhen's words would not be fulfilled. One hundred taels, that is equivalent to two years of salary in Qipinzhi County.

Liu Yifei saw Zhu Youzhen for the first time, he didn't know why this young prince made mine grenades, and he spared no expense, but he didn't believe in the king He could offend Deqi, besides, he also wanted to see the magic of the mine grenade: "Don't you still believe it?" It is serious to hurry up and develop a mine grenade. ”

"You don't have to worry about this, this king will pay fifty taels as a deposit, as long as you can make what I need, the money will not be less than you." Zhu Youzhen asked Xu Yingyuan to take out a silver ticket of fifty taels and handed it to several craftsmen, seeing that they took it tremblingly, and added: "You must strengthen cooperation, seize the time to make the things that this king wants, don't be suspicious of each other, I will have good things for you to make in the future, as long as you have the ability, money, you will definitely not make less money." ”

An older craftsman took the silver ticket, carefully observed it, and found that it was really a silver ticket, so he was relieved. In the Ming Dynasty, there was no such thing as counterfeiting, and there was no fake silver ticket, "Lord, we will do our best to make mine grenades and live up to the trust of the prince." ”

"Well, this king also believes that you can make a mine grenade, so don't forget to inform this king when the time comes. In addition, it is necessary to keep it secret from the outside world for the time being, and whoever leaks the secret will not only not be able to get a son from this king, but the king will also severely punish him. ”

With the emperor's 10,000 taels of silver, the training of the Fenwu Battalion will continue, and the craftsmen of the Firearms Bureau have taken over the manufacture of mine grenades, once successful, it will be of great help to the study of flintlock pistols, the principle of flintlock pistols and the principle of mine grenades are very similar.

Leaving the Firearms Bureau, Zhu Youzhen was in a very good mood, the climate in early summer was neither hot nor cold, the soft grass under his feet was more pleasant than Simmons in a five-star hotel, and the slight cool breeze was like a lover's hair, gently rubbing against his bare chest, and the warm sun that had gradually sunk in the west expanded the thoughts of the human body in an infinite space. Zhu Youzhen jumped on horseback and waved at Xu Yingyuan, "Let's go, go home." ”

When he came to the barracks again, Zhu Youzhen immediately sent a message to the guò battalion headquarters: The soldiers of the Fenwu battalion have a meal of meat to eat every day. With the 10,000 taels of silver allocated by Zhu Youxiao, it is enough for the soldiers of the Fenwu Battalion to eat for a while, and as long as they are brilliant in the military parade, they may be able to get some rewards from the military department.

The soldiers of the whole battalion were shouting and cheering. Some of the keen-eyed officers and soldiers immediately realized that it had something to do with Wang Xin. Since Wang Xin, a rich second-generation man, became a staff officer of the battalion headquarters, the army has undergone great changes: the amount of training has increased, exercises are conducted every day, military songs are held, military skills competitions are held, food can be eaten, and now meat can be eaten every day. Although the training was very tiring, the food in the Fenwu Battalion could be said to be the best in the entire Jingshi Army, and they felt that Zhu Youzhen really regarded them as brothers and did not despise them from above. When you can eat well, the respect of others is definitely the first need of people. They did not know the true identity of Wang Xin, only that he was the son of a wealthy merchant. Anyway, it's in his own interests, so what's the matter? Although Zhu Youzhen was young, the soldiers still served the young battalion staff officer.

The content page of the training in the barracks was gradually enriched, especially the soldiers of the special combat team, in addition to the normal training every day, Zhu Youzhen also personally taught the Xuji Sword Technique, and at the end of the training every day, some soldiers were so tired that they didn't even bother to take a shower. Since the launch of the military skills competition, there has been a gradual competition between the battalions. The cavalry guard has jurisdiction over three thousand households, and the thousand generals are Zhang Heng, Wang Qiang, and Qian Limin, and they do not give in to each other in training, and some training items are higher than the standards set by Zhu Youzhen. There are also three thousand households in the infantry, and although Li Xing, Wu Bing, and Jiang Gen have good personal relations, they are also unambiguous under the drive of the entire training environment, for fear that the soldiers will embarrass themselves, and the training is no less ruthless than that of the cavalry, and they often take the lead.

After another three days, in order to make the training more interesting, test the results of the training, and improve the actual combat ability of the soldiers, the Fenwu Battalion held a military actual combat exercise.

Military exercises were originally a regular training activity of the Ming army, but in the late Ming Dynasty, the political activities gradually spread to the army, and the exercises were often confined to the form, and some armies even stopped actual combat exercises.

Before the exercise, Zhu Youzhen gave a brief lecture and emphasized the rules of the exercise: Ten miles away from the barracks, there was a dirt slope called Wolf Ridge, and Wu Bing and Li Xing led the soldiers of their headquarters to attack from the north and south respectively to seize Wolf Ridge.

Both sides are ten miles away from Wolf Ridge, Li Xing from the north, Wu Bing from the south, set off at the same time. In the morning, the two sides reconnoitred the terrain, and in the afternoon, the exercise began at the beginning of the day.

In order to reduce casualties, all the equipment is wooden, and there are lime pools along the way and in Wolf Ridge, and the top of the equipment is stained with lime, and as the basis for attacking the enemy, the soldiers must wear black clothes.

Any white spot in the head or body, or two white spots in the limbs, must be withdrawn from the exercise and treated as serious injury or death.

In order to observe the armies in the vicinity, the battalion headquarters sent supervisors to the armies on both sides of the exercise. The supervising army was covered with a red cloth on their arms, and the supervising army was not allowed to make any suggestions to the two sides of the exercise, and the soldiers of both sides were not allowed to launch an attack on the supervising army.

Before the time came for the exercise, the soldiers of both sides entered their predetermined areas, and the commanders of both sides began to give lectures, boost morale, and explain their strategies and tactics.

Li Xing is a native of Shandong, tall and mighty, with dense hair and thick beard, and is famous for his strength in the Fenwu camp. "Rabbit cubs, half an hour, you must reach Wolf Ridge, and you must take Wolf Ridge in the time of a stick of incense." Li Xing's lung capacity should be good, and the sonic boom is all over the camp.

"Yes." The voices of the soldiers are also shocking, and there are really no weak soldiers under the strong generals.

"Leave two hundred people behind the palace as reinforcements, and the rest will set off before the time comes." Li Xing glanced at the soldiers, and was very satisfied with the neat queue, he had never seen such a neat queue since entering the barracks.

Wu Bing's stature was moderate, and compared with Li Xing, he was inferior to his opponent in terms of height, strength, and lung capacity, but Wu Bing did not think that his soldiers would lose to Li Xing.

"Five hundred people are the front team, and they can rush to Wolf Ridge as quickly as possible; 300 men are flanks, and when the enemy and us are in the middle of the battle, they attack from the enemy's flank, regardless of casualties, charge and fight violently, and must cut into the middle of the enemy's army, so that the enemy's vanguard will be attacked in front and behind; Another 200 people were reinforcements, and when they saw the fireworks, they rushed to meet them. Wu Bing's voice is also good, his voice is thick, after arranging the strategy, his eyes swept over the faces of the soldiers one by one, "Brothers, are you afraid of Li Xing's duck throat?" ”

"Don't be afraid." The soldiers answered in unison, and cut it to the ground.
