The rumors ended with the wise man, but Ning Wen didn't think so. It was probably the supreme leader who spoke. So judging from the news from Li Zhi, no one mentioned the incident that day, whether in the palace or in the court.

The blast furnace of the weapon supervisor was put into production again. In addition to Zeng Er and Zhang Kunheng and Ha, there was also a powerful man with Kong Wu. However, the strong man held a thick stack of records in his hand. Huailiang had a strong desire for knowledge and studied steelmaking knowledge with Master Zhou all day long. It was mainly practice. Master Zhou could not tell the reason in theory. This was exactly what Ning Wen was very depressed. He wanted Master Zhou to record the things in his mind completely, and at the same time he had to analyze and organize it. It was basically impossible for Master Zhou to be a craftsman like Master Zhou. Huailiang was not this material. Except for Liu Rengui, the weapon supervisor, who had a relatively high level of knowledge, all made a living with practical experience.

"Super Fang, this matter is quite a matter. Not only is it a compilation of books, but it also needs to systematically record Master Zhou's experience in sentences that are easier to understand. It also needs to compile a textbook based on this so that it can be taught to the young people who are willing to engage in steel manufacturing in the future!"

"Shaojian, in this way, isn't Shaojian planning to write books and biography? These techniques are the top secrets of this dynasty. The fewer people know about it, the safer it is. Guangcheng, I am worried that Your Majesty will not agree."

Fang Yiai’s worries are not without reason, and Ning Wen is the same, but Ning Wen is confident to convince Li Shimin that sooner or later it will be taught to the next generation. How to teach them in full is also a question. Who will teach and who will learn?

Maybe it's still a bit early, but Fang Yiai still needs to organize the method of steelmaking. Let's sort out this out first, and then talk about the future.

Ning Wen thought that the rumors would be gone, but the news from the East Palace made Ning Wen helpless. Li Chengqian's leg injury healed, but he was always lame. Not only did his right foot not use force to walk, but he also often felt unbearable. He gradually became irritable. Not only did he beat and scold eunuchs and palace maids, but even officials at all levels in the East Palace spoke harshly. Today, he actually beat the official of the Zhan Shifu Mansion and threatened to ask for someone's head. This matter came to Li Shimin's side. Li Chengqian refused to admit his mistake. For a moment, the father and son were like enemies.

Ning Wen can't take care of that much anymore. Time is very tight. Now the weapons supervisor is united and is working hard to devote himself to the work of casting artillery. Ning Wen cannot be idle. He sticks to the test range every day. Today he is going to experiment with the power of the flowering projectile.

This projectile must be more careful. The first experiment not only verifies whether the flowering projectile will explode, but more importantly, it is to verify whether the projectile will explode. It is also difficult to help but a thin layer of iron sheets. It is not known whether it can block such a high temperature in the barrel. If the gunpowder in the projectile is ignited and explodes in the barrel, it is a huge hidden danger. The main purpose of today's experiment is to check whether the above situations will occur in this design.

With the sound of a cannon, Ning Wen and the people who were squatting in the command post all breathed a sigh of relief. Looking at the complete Tianwei cannon on the position below, everyone shouted excitedly.

Diao Gui was still awake, so he quickly took a few foundry masters to the position and quickly checked whether the structure of the cannon was intact. Ning Wen followed him and Diao Gui looked carefully. Several foundry masters nodded in agreement, so he reported to Ning Wen that everything was intact and that the next experiment could be carried out.

At the same time, good news came from the target area about two hundred feet away. Hundreds of life-sized wooden models there were completely destroyed, and they were completely crushed by the explosion center. With the explosion center as the origin, the models with a radius of one zhang were severely damaged. About 80% of the models with a radius of ten feet were struck by iron blocks filled in the projectile, and they were all embedded in whole pieces. If they were living people, they would probably not be able to afford to be seriously injured, and at least they could not participate in the battle.

Taking advantage of the heat, I tried thirty flowering bullets in the morning. Looking at the records in Diao Gui's hand, thirty shells, ten shells exploded immediately after landing, five bursts exploded in about a blink of an eye after landing, five paused for a moment before they exploded, five bursts exploded before landing, and five bursts exploded in the air before landing, and five fired!

The data is very detailed and much better than expected. The main problems are silence and air explosion. These two problems need to be improved. A group of people analyzed on the cannon position what causes the deviation of the projectile explosion time.

"Young supervisor, joining the army, Zheng probably caused by the size and thickness of the holes of the flowering projectile."

The supervisor named Zheng is responsible for the production of projectiles and finds the reasons based on his own defects in the production process.

"What Zheng Jian said was inappropriate. He asked He to say that the length of the medicine twist and the amount of gunpowder filled with different amounts, which caused inaccuracy in the explosion time."

The supervisor named He is responsible for the filling of the entire hollow projectile and the installation of medicine twists.

For a time, everyone thought that He Jianzuo’s opinion was relatively correct, but not many thought that this was impossible to solve. The medicine twists were always made by the students based on their experience, so there was a situation where the charges were inconsistent.

The solution is very simple, weighing and running water, so Ning Wen turned the production of the projectile into an assembly line mode. Starting from the casting of the projectile, the weight of each projectile is strictly unified, and the positive and negative errors must be less than one percent. This is also the smallest difference under the conditions of no accurate measurement tools. Then it is the filling ratio and filling weight of the iron slag and gunpowder. The filling ratio and filling weight must also be accurate to one percent. Then the production of gunpowder twists. This is the key point. The main focus is on the thickness of the medicine twist and the amount of the filling gunpowder. If the accuracy requirements are high, it cannot be achieved. It is all manual work. Controlling the accuracy to about ten percent is already the limit of these craftsmen. This is the only way to do so before filling machines and more advanced medicine twists.

After the manufacturing process of the flowering bullet was arranged, the group of people began to start manufacturing. The next experiment was scheduled to be ten days later. At the same time, the second Tianwei cannon will be offline in ten days, which will probably catch up with the experiment. At that time, the two cannons will be able to test the destructive power of the cluster shooting of the artillery.

"In three days, Your Majesty will issue an edict. Haha, Ning congratulates Young Master Diao on his behalf!"

Ning Wen left Diao Gui alone, which was what Li Shimin meant. Liu Rengui didn't know how to move, but he was promoted, and his position was unclear. Li Shimin's meaning was to transfer to the school, but after all, he had entered the center. Liu Rengui should be secretly happy at home now.

"More, thank you for being a little prisoner!"

Diao Gui was a little stunned for a moment and couldn't find anything to say. He was just very excited. His dream position became a reality. Looking back on his days in Qianniuwei's house and looking at the days of the Weapon Prison, compared with the two, Diao Gui felt that the Weapon Prison was like the first born morning sun. Not only did His Majesty value the Weapon Prison, but more importantly, he personally experienced the birth process of the unique powerful cannon. Diao Gui was really grateful to Ning Wen. He had no backer and no money. In less than a year, he became the second-person in the Weapon Prison. This made Diao Gui cry out for not being grateful to Ning Wen.

"Do it well, Your Majesty will see it. There will be more firearms to be made in the future. Diao Shaojian's burden is very heavy!"

Ning Wen laughed a few times in his heart. Why did he feel like he was a young man? Did he unconsciously have such an official power when he reached a certain level? Three days later, Diao Gui was promoted to the Weapon Supervisor, and Ning Wen himself would also be restored to the position of chief. It seems that Li Shimin was already very annoyed by the prince's behavior. It is a matter of suppression. It depends on Li Chengqian who asked not to know what Li Shimin meant. If he thought about it again and again, he was afraid that the idea of ​​ascending the throne in advance would become stronger. Ning Wen still couldn't remember when Li Chengqian was preparing to seize power. Ning Wen still deliberately stopped Li Chengqian. No matter how he said he was not a bad person.
