In a few months, Li Shouzhen left the experimental site for the first time and went to see Qiudongye under the guidance of a master craftsman. Until then, he discovered that the distance between him and Qiudongye was only a small hill. This side of the mountain was the experimental site where he was located, and the other side of the mountain was the place where these weapons were made.

Staying on the third floor of a building, looking at the rows of bungalows below, staring at the screen wall at the end of the room, the four big words "Sing Jing" on it were written in bright red cinnabar, which was a bit dazzling.

The gray bungalow does not look conspicuous at all. It is hard to imagine that the powerful weapons I threw out these days were produced from here.

The sound of footsteps came from outside the door. Li Shouzhen withdrew his gaze, raised his chest and abdomen, and sat upright. The person who wanted to see him was a fourth-rank official at that time. Compared with him, he was one in the sky and one in the ground. The difference in the ranks between the two was a bit too far.

The door was pushed open with a creaking sound, and an old man in a coarse cloth coat walked in. Li Shouzhen glanced at him and immediately withdrew his gaze.

"Personnel Li, right?" To his surprise, the old man walked directly to him and asked.

"Who are you?" Li Shouzhen looked at the other party with some confusion.

"I'm Qiudongye!" the old man said with a smile.

Li Shouzhen yelled and jumped up all of a sudden. He had never expected that the old man in front of him who looked ordinary and similar to a cleaner servant was actually the fourth-rank official of the dynasty and the dean of the Weapon Research Institute.

"I will be rude." He saluted Qiu and Dongye with a red face.

"Haha, nothing." Qiu Dongye waved his hand, "Today I see you, it's a conversation between a weapon maker and a user. It's not a meeting between superiors and subordinates, don't be so restrictive."

Li Shouzhen said unconsciously: "I didn't expect..."

"Didn't you think of anything?" Qiu Dongye laughed and said, "I didn't expect that the fourth-rank official of the dynasty was an ordinary old man like me?"

Li Shouzhen lowered her head embarrassedly.

"Actually, it's just an ordinary old man." Qiu Dongye smiled and said, "Ten years ago, I was still a lowly craftsman. If I hadn't been to the Ming Dynasty and the appreciation of His Majesty, I wouldn't know where to beg for food or struggle just to eat for a bite of food! Come, sit down and say."

Li Shouzhen kept shaking her head, but nodded again immediately, obviously still feeling a little nervous.

"Don't be nervous, don't treat me as a high-ranking official, just treat me as a craftsman." Qiu Dongye personally poured a glass of water for Li Shouzhen and said, "In fact, over the years, the officials have been promoted constantly, but I am really not the material for being an official. I can't learn the power of those high-ranking officials I have seen before. In fact, people like me, who stand in the workshop, are all craftsmen. This official brother, His Majesty, just let me have more room to play with my strengths. Come, drink a little water, let's talk slowly."

"Thank you, sir." Li Shouzhen raised the cup and drank the water in the cup in one gulp, and then his heart was a little calmer.

"For the past few months, you have been using the weapons we made to tell me about your feelings, the most realistic feelings, from its power, how to use them, etc., everything is very detailed." Qiudongye said: "You must be clear that these weapons will be distributed to the army in the end. If they have any defects and are not discovered, they will kill people when they go to the battlefield."

"Yes, Lord Qiu." Li Shouzhen cleared his throat and said, "The power of the grenadines is unquestionable. To be honest, when I used them for the first time, Mo Jiang didn't fall asleep all night. Later, even when he fell asleep, there was a huge sound in his dream, the explosion of fire and the flying residue. There was no doubt that they would definitely become a weapon on the battlefield."

"From the beginning to now, which one is the best and which one is the most powerful?"

"The most powerful are the ceramic bullets we have recently started to use with patterns." Li Shouzhen said, "I carefully observed that the fragments were basically cracked according to the patterns engraved earlier. The destructive power of the sharp ceramic pieces is amazing. They can be deeply embedded in the wood and can easily tear the leather armor, but they still have no strength to the iron armor."

"So do you think there is anything that can be improved?"

"If the one who loads no longer uses clay pots, but instead uses iron cans, the powder will feel that the effect will be better." Li Shouzhen said hesitantly.

Qiu Dongye laughed, "It's really not easy to think of this, but it's much more troublesome to make the iron shell. Now we are still working hard for this project." He pulled open the drawer on the table, took out a dark thing from it, and handed it to Li Shouzhen.

Li Shouzhen carefully looked at the things in his hand. They were made of iron, and there were patterns engraved on them, dividing the bullet into diamond-shaped patterns.

"The process is not mature, and I am still exploring how much gunpowder should be installed inside. In the initial experiment, sometimes it cannot be blown up, and sometimes it will be blown into several large pieces, which will not meet our requirements at all, but it will definitely be able to conquer it in the future." Qiudongye said.

Li Shouzhen nodded excitedly: "If I could use the iron bullet, I would feel that I could easily tear through the iron armor."

"What you will see in the future, is there any inconvenience during use?"

"Yes!" Li Shouzhen said: "The first thing is the throwing distance. Sir, the arm strength of the last general is good, but he can only throw it to seventy steps. It is great if ordinary soldiers can throw it to fifty steps. But you also know that the range of a crossbow can cause fatal damage beyond a hundred steps, and the shooting range of a strong bow is even longer. In battle, if we want to throw a grenade into the enemy group, it is obvious that it will cost a lot."

"This problem cannot be solved yet." Qiu Dongye nodded.

"Then it's the problem of the lead." Li Shouzhen said: "When fighting like this, the restrictions are too great. Each of us must bring a fire-shooting object and ignite the lead during the battle. If it's a rainy day, it's basically impossible to use it."

"We still have other weapons about projection distance, for example, using improved trenchers to throw gunpowder bags, which is actually a bit simpler." Qiu Dongye pondered for a moment: "But what you said is not available due to the weather, which is indeed a problem. But now, we have not found a solution to him."

Qiu Dongye scratched his head in embarrassment. He thought of these problems, but there was no solution to them. Looking at Li Shouzhen's desire to speak but stopped, he couldn't help asking: "What do you want to say?"

"Sir, we often use flint to create fire. When two flints collided, sparks would burst out. If we could put flint inside the bomb body, and then add a rope or something outside. Once we pulled, flint collided..." At this point, he suddenly stopped.

Qiudongye laughed: "The spark came out, but the grenadier exploded immediately. This was not killing the enemy, but committing suicide." Qiudongye stopped, suddenly stood up, and turned around several circles in the house. "This idea is OK, it cannot be used to drop bombs, but we can use it to make another weapon."

He looked at Li Shouzhen excitedly, "Your reminder is very important."

"Didn't you just say this is not OK?"

"Grenades are not good, we can use them to make something else." Qiudongye laughed: "For example, we don't need to pull ropes, but design a machine, bury the grenade in the ground, and quietly expose a little mechanism outside. Well, if you don't show it, then someone stepped on it, and the machine led to flint and collided, sparks burst out, and gunpowder was detonated. With a rumbling sound, will those who step on this machine, and those around him, be killed by blowing them?"

Li Shouzhen shivered. Thinking of the wooden people on the experimental field who were blown up to pieces, he suddenly felt that this idea was really sinister. He buried the grenade in the ground and let the enemy step on it and detonate it. This Lord Qiu's head was indeed different from that of ordinary people.

Qiu and Dongye clapped his hands excitedly, "This is a good idea. I have to write it down and try it back. By the way, I think I'll discuss the idea you just mentioned to Master Xu Lai to see if it can solve the problem of delayed explosion. If it can be solved, then the problem of rainy days you just mentioned can also be solved."

Just as Qiu Dongye and Li Shouzhen were talking, Qin Feng was also reading the top secret memorial on the application of gunpowder in the Weapon Research Institute.

Very good, the grenade was made. Although it still looks very primitive, everything developed from the most primitive things. With this foundation, they will gradually make better things.

Throwing explosive packs with improved catapults can barely play the role of killing and attacking the enemy, but where is the artillery that I most hope for?

The most primitive artillery does not require much technical accumulation. After the appearance of gunpowder, it was the first long-range attack hot weapon to appear. If the most difficult thing to make is the gun barrel, it is the gun barrel. However, with the current technology of Daming iron and steel making, it should not be difficult to create a qualified gun barrel. Now the Ming Dynasty should be able to directly cross the bronze cannon to make cast iron cannons.

Only when the cannon appears can the musket be slowly applied. However, before the smokeless gunpowder was developed and before the technology of loading speed was improved, Qin Feng felt that the musket was not very useful, and it was far less useful than crossbows and bows.

"It seems that I have to give them a little tip!" Qin Feng sighed. Although he did not understand the artillery manufacturing technology, it did not prevent him from drawing a cannon appearance sketch and then annotating what this thing is used for. As for turning this sketch into a real weapon and solving one of the technical problems, it is the problem of the masters of autumn and winter wilderness.
