Hu Guang thought so and issued an order: "Transfer to the Minister of Works and the eunuch in charge of the military war."

There is insufficient training in Beijing and most elderly and weak, so it is too late to say anything now, so I can only put it aside for the time being.

After a while, the Minister of Works, Nan Juyi, and the eunuch Liu Shiduo, the eunuch in charge of the military battle, immediately arrived at the top floor.

Hu Guang looked at them with a serious face and said, "I should have seen the battle of Jianlu's siege just now, right? Do you know why I summoned you and others?"

He did not use the title of "Qing and others" to express his unhappiness. After Nan Juyi and Liu Shiduo looked at each other, Nan Juyi bowed and replied: "There are many firearms that have blown up, and the city defense equipment is insufficient. I know that I am guilty!"

In total, two cannons exploded and more than 30 bird guns exploded. This is just a defense of a section of city walls. If all Jianlu attacked and the city defense line expanded, more firearms would probably explode.

There is something obvious to all. Neither Nan Juyi nor Liu Shiduo cannot deny it. He also knows that there must be an explanation for this matter. When he heard the emperor's question, he pleaded guilty first.

Hu Guang saw that his attitude was good, so he calmed down a little and said, "Nan Qing has just taken over as Minister of Works. If I punish you for this, it would be unfair. But you have also seen that Jianlu is cruel and eyeing the capital. The supervision of city defense equipment must be stepped up, and it is not an exaggeration to work day and night. But at the same time, you must pay attention to the quality. If there are any mistakes, I will never give up!"

Based on the memory of Emperor Chongzhen, he knew that the former Minister of Works was Li Fengxiang. Because of poor military weapons, he was dismissed before he traveled through time and also beaten to death three doctors in charge of specific affairs.

There were actually two other reasons why Hu Guang did not punish Nan Juyi. One of them was from Emperor Chongzhen's memory that Nan Juyi served as the governor of Fujian around the third year of Tianqi. He resolutely fought back against the Dutch invasion, launched the Battle of Penghu, and drove away the Dutch, which was considered to be a contribution to the country.

Another reason is that whether it is artillery or bird guns, those soldiers are not trained enough, panic in the battle, and excessive fill of gunpowder will also lead to a blowout.

When these thoughts flashed through Hu Guang's mind, he suddenly became stunned. How could your sister forget this? Without waiting for Nan Juyi to respond, he immediately added: "The newly built cannons and bird guns are measured by craftsmen, and then they are fixed with paper..."

He explained one of the most basic common sense in later generations, which is the method of fixed loading, and then immediately looked at Man Gui and said, "Manqing, you should also speed up the inspection of existing weapons. If the quality is not up to standard, you will be returned to the furnace. If the quality is not up to standard, you will be allowed to prepare fixed loading. All the requirements will be supplied by Nanqing!"

"Ding, achievement value +1, comes from Nan Juyi, Minister of Works!"

"Ding, achievement value +1, from the military battle eunuch Liu Shiduo!"

Hearing the system prompt, Hu Guang couldn't help but sigh inwardly. Man Gui had no contribution, so he must have been squeezed out by himself. From then on, there was a missing person with contribution value!

"Your Majesty is wise!" Nan Juyi and Liu Shiduo bowed and praised at the same time.

"I will obey the order!" Man Gui's answer was always different from others. After he finished speaking, he even looked at Nan Juyi and Liu Shiduo and asked loudly: "When making fixed reloads, you need to check the craftsmen and do not confuse the use of gunpowder!"

When Hu Guang heard this, he asked curiously: "Manqing, what is confusing the use of gunpowder?"

"When you go back to Your Majesty, gunpowder is divided into multiple uses according to the ratio, including launch and explosion..." Speaking of these, Man Gui is also a professional, talking freely.

In fact, at the end of the Wanli period, after Sarhu was defeated, the court summed up the lesson. One of them was that the official Yingzhen, the minister of the household registration department, proposed to reform the martial arts and improve the rationality of the examination content.

The original martial arts examination only included strategies to evaluate the archery, horse and martial arts. This reform added the examination content of "campaign, mines, gunpowder, chariots, etc.".

Although Man Gui was not a martial artist, he had been promoted from the bottom of the army to level one by one, so it was naturally impossible for him not to know these contents.

However, Hu Guang, the first time he heard it, was very fresh and focused.

When Nan Juyi saw it on the side, he couldn't help but breathe a sigh of relief. He was really scared by the emperor just now, and casually said the way to load the bullets. He almost thought that the emperor was a heroic figure and a genius who was never born.

Thinking about it, the emperor was just a vassal king who was good at the deep palace before. Even if he moved out of the palace, he had never left the Xinwang Mansion. How much knowledge can a young man with no experience have? It was amazing that a fixed-loading bullet suddenly appeared just now.

It was normal to look at the emperor's performance at this time. Nan Juyi thought about it and smiled secretly: What is the emperor who is extremely smart and wise and powerful is just a polite word.

However, although he thought so, he could not control the commotion in his heart. When Man Gui finished his speech, he directly added: "Your Majesty, all gunpowder is mainly saltpeter, sulfur, and wood ash is supplemented by wood ash. Nitrity is the most yin, sulfur is the most yang, and Yin and Yang are in an unobstructed way. When it comes out, the person is intoxicated, the soul is scattered and the soul is scattered. Any nitride is the main direct, and the direct attack is the nine and the sulfur is one. The sulfur is the horizontal, and the critical attack is the seven and the sulfur is the third..."

Man Gui mainly talked about the purpose, and he explained it from the specific ingredients. Fortunately, Hu Guang had the memory of Emperor Chongzhen and could understand his words. He said that saltpeter had great explosive power in vertical direction, so the gunpowder used for shooting was nitr nine sulfur one; while the sulfur had great explosive power in horizontal direction, so the gunpowder used for blasting was nitr seven sulfur three...

Hearing this, Hu Guang suddenly remembered the weakness of artillery he had discovered before, thinking about finding a good defense method, and suddenly a noun appeared in his mind.

He immediately interrupted Nan Juyi with a slight slight slight expression and said, "Yes, I have an idea. In the subsequent battle to defend the city, the Red Barbarian cannons, general cannons, etc., should not waste gunpowder if there are large siege equipment that moves slowly or does not move outside the city, and they will only be fired and destroyed..."

When Nan Juyi heard the emperor speak, he had to shut up. However, when he heard what Hu Guang said clearly, he was surprised and wanted to advise the emperor from a professional perspective.

At this moment, Hu Guang continued: "Compare most of the gunpowder into explosives, and then make it into large explosives, use iron shells, or porcelain shells, and require it to be filled with objects that hurt the enemy, iron nails, gravel, etc. that have great lethality. Well, you can also fill the outer layer with tung oil and other flammable objects. Just such an object, ignite the fuse and throw it into the city Jianlu pile under the city to explode, or use a catapult to throw it into the far-reaching Jianlu pile to kill Jianlu, how about it?"
