Looking at Xu Guangqi who walked in, the Emperor of the Apocalypse and Sun Chengzong were stunned, and what appeared in front of the two people was not the old man with a strong spirit, but a worker who seemed to have just come down from the quarry. The clothes on his body were tattered and dirty, his face was black and white, and his hair and beard were messy.

There is another person behind Xu Guangqi, who looks similar to Xu Guangqi, and his face is also the same. But this one is much younger, and I can't see what it looks like now.

"Minister Xu Guangqi see Your Majesty, long live my emperor, long live long live!" Coming to the center of the main hall, Xu Guangqi hurriedly picked up his clothes and knelt on the ground, and said loudly.

The Emperor of the Apocalypse hurriedly walked to Xu Guangqi's side, helped Xu Guangqi up with both hands, and said quite unhappily: "Xu Aiqing, I have already said that you can be exempted from this kind of gift." ”

"Back to the emperor, the minister has always been on the side of the imperial village, and he rarely has the opportunity to see the emperor. If you salute like the emperor, you are really losing your duty as a minister. Xu Guangqi stood up with the support of the Emperor of the Apocalypse, smiled quite awkwardly, and said a little embarrassed.

The Emperor of the Apocalypse glanced at Xu Guangqi helplessly, then at the young man kneeling on the ground, and asked in a deep voice, "What's your name?" ”

"Avoidance, student Sun Yuanhua." Sun Yuanhua didn't raise his head, still touched the ground, and said respectfully.

Listening to Sun Yuanhua's tone, the Emperor of the Apocalypse nodded slowly, there was no excitement, no fear, it was really not easy. However, Sun Yuanhua said that he was a student, obviously he was not an official, but he should have a meritorious reputation.

With a gentle wave of his hand, the Emperor of the Apocalypse said softly, "Get up!" It's cool on the ground! Laughing and laughing, he walked behind the dragon book case and made it to his dragon chair.

"Come on, move a chair for Lord Xu!" The Emperor of the Apocalypse looked at Wang Chengen. Commanded loudly.

At this time, Sun Chengzong and Xu Guangqi were already greeting each other, the two had met several times, and Sun Chengzong was one of the few people who knew what Xu Guangqi was doing. Now seeing Xu Guangqi's appearance, Sun Chengzong knows that this person is similar to himself, but the way to serve the country is different!

He bowed to Sun Chengzong and said respectfully: "Xiaguan has seen Lord Sun!" ”

Sun Chengzong hurriedly supported Xu Guangqi. said with a smile: "Lord Xu, don't be like this, the emperor is not subject to the courtesy of adults, and the old man does not dare!" ”

"Master Sun is joking!" Xu Guangqi also knew Sun Chengzong's status and personality, smiled indifferently, and said in a brisk tone.

Both of them sat down, and the Emperor of the Apocalypse slowly spoke: "Xu Aiqing, what are you doing here?" How did it get like this? ”

"Back to the emperor, since the last time the emperor said that the production of the current artillery would be stopped, the minister has been studying the new type of artillery that the emperor said. There has just been a little bit of progress. The minister is trying to improve. Xu Guangqi wanted to stand up and say, but was motioned by the Emperor of the Apocalypse to sit and say before he said in a deep voice.

Sun Chengzong on the side was slightly stunned, he didn't expect that the Emperor of the Apocalypse would actually improve the production of artillery again, and he would actually develop a new type of artillery. For the last new artillery, Sun Chengzong still remembers it vividly, and the huge artillery that is always erected on the city wall is really too powerful. The battle of Shenyang City used that kind of artillery, is there a more powerful artillery?

He nodded slowly. The Emperor of the Apocalypse said with a smile: "Regarding the record of gunpowder in Qi Jiguang's "Ji Xiaoxin Book", has Aiqing read it?" Is there an experiment with the above statement about granular gunpowder? ”

Xu Guangqi was slightly stunned, thinking that the Emperor of the Apocalypse would ask some questions about artillery. Unexpectedly, I actually asked the question of gunpowder first. After a slight sigh, Xu Guangqi said in a deep voice: "After this minister went back, he studied it carefully, did it according to Qi Dashuai's method, and then used granular gunpowder to make cannonballs and primers, which not only had a long range but were also more powerful than the original. After Weichen's experiment, the range was almost half higher than the original. That's probably what the power looks like! ”

Sun Chengzong on the side was confused, and he naturally read Qi Jiguang's new book of Ji Xiao. For some of the tactics and things in it, Sun Chengzong admires and likes it very much. He has also read the account of granular gunpowder, but he pays more attention to tactics and tactics, and the manufacture and transformation of artillery are not Sun Chengzong's strong points.

However, when Sun Chengzong heard about the use of granular gunpowder. The power and range of the artillery could be increased by more than half, and I was immediately taken aback. If this is calculated, just by improving this item, the Hongyi cannon can not only hit ten miles away, but also has much more power than the original.

Sun Chengzong's mind is constantly turning, since the Emperor of the Apocalypse and Xu Guangqi want to develop a new artillery, I am afraid that the improvement is not only this point, this is probably a foundation.

The Emperor of the Apocalypse nodded slowly, in the real history, many of Qi Jiguang's things failed to play a role because of party disputes. Qi Jiguang himself was belittled by the imperial court, not to mention the books he left behind. Now that it can be really used, I believe that Qi Jiguang will be able to see it if he has knowledge.

"This has been done very well, and all the gunpowder in the future will be produced like this, but the formula must be kept secret first, and don't tell the story of Ji Xiaoxin's book." The Emperor of the Apocalypse groaned slightly, and said in a rather serious tone.

The Emperor of the Apocalypse and Xu Guangqi were talking there, Sun Chengzong sat on the side and frowned as he listened, and he couldn't help but interject: "Lord Xu, can you talk to the old man?" The old man really didn't understand when he heard it. ”

Xu Guangqi was slightly stunned, smiled and looked at Sun Chengzong to try his look, and motioned for him to look at the Emperor of the Apocalypse. He didn't expect that Sun Chengzong, the dignified scholar of the first assistant university in the cabinet, would have such a side.

After receiving Xu Guangqi's hint, Sun Chengzong reflected that this was not a few people discussing things, but a prelude to facing the Emperor of the Apocalypse. Bowing to the Emperor of the Apocalypse, Sun Chengzong said respectfully: "The emperor forgives the sin, and the minister has given a salute!" ”

Seeing Sun Chengzong's embarrassed look, the Emperor of the Apocalypse suddenly laughed, obviously being able to see his teacher's appearance, no matter what time the students would have some snickering.

Seeing the playfulness on the face of the Emperor of the Apocalypse, Sun Chengzong felt even more embarrassed, and it seemed that he was sitting on the side.

The Emperor of the Apocalypse felt that it was almost over, waved his hand lightly, and said with a smile: "Sir, don't worry, it's a little trivial." Sir, I understand the heart of serving the country. He turned his gaze to Xu Guangqi again, and said with a smile: "Xu Aiqing, since Mr. wants to know, then you can talk to him!" ”

"Yes, Your Majesty!" Bowing to the Emperor of the Apocalypse, Xu Guangqi said respectfully.

Turning his gaze to Sun Chengzong, Xu Guangqi was about to start talking, his expression also became extremely serious, as if he was about to start an extremely sacred thing.

Sun Chengzong also became serious at this time, sitting upright, looking like he was listening.

Seeing the expressions of the two people, the Emperor of the Apocalypse began to feel very funny, but after watching it for a while, the Emperor of the Apocalypse couldn't laugh anymore. My heart is full of emotion, this is my own courtier, the loyal minister of the Ming Dynasty, and it can also be said that it is the hope of the Ming Dynasty.

"Your Majesty is very dissatisfied with the variety of artillery varieties and the difference in power, so he ordered His Majesty to develop a new artillery. This type of artillery should have a longer range, more power, and at the same time a smaller size. Therefore, everyone in the firearms factory is invested in this, and the first step we have to solve is the problem of gunpowder, only better gunpowder can exert greater power. This idea was still thought up by the emperor, and after consulting the classics, I found that it had already been recorded in General Qi's book. Xu Guangqi said slowly, and he was not very embarrassed to say this, I don't know if he was lamenting Qi Jiguang's unfair treatment.

Sun Chengzong on the side listened to it, and admired the talent of the Emperor of the Apocalypse even more. If you really have such artillery, you will be able to strengthen your own training of the new army in the future.

After a slight mutter, Sun Chengzong said in a deep voice: "First mix the nitrate and charcoal in proportion and pound it many times to make it fine. Add an appropriate amount of water or shochu to mash it a second time to make a puree. After drying, the finished granular gunpowder can be obtained by crushing and sieving, and the gunpowder obtained is also used in different firearms with different sieve hole sizes. These are all records in General Qi's book, but the methods and proportions used are very vague, presumably only General Qi himself knows, right? ”

In response to Sun Chengzong's question, Xu Guangqi nodded with a smile, and said with pride in his tone: "My lord is really knowledgeable, General Qi naturally won't describe it in such detail." Xiaguan and others experimented many times according to the records in the book, and probably figured out the use of this gunpowder. Later, General Qi Jin came to the capital, and the lower officials privately approached General Qi and asked some things about artillery. Now there is no major problem with the use of granular gunpowder. ”

Sun Chengzong had to sigh in his heart, Xu Guangqi deserved to be a talent in firearms, and it was not for nothing that the Emperor of the Apocalypse valued him so much. Nodding slowly, Sun Chengzong Xu Guangqi continued.

After a slight hesitation, Xu Guangqi spoke again: "The trial artillery is divided into two types, one is a small artillery suitable for two handling. The other is an improved version of the Frankie gun. Adults should know that the rate of fire of the Frankie cannon is much faster than that of the Hongyi cannon, but the range is much worse. The largest Frankie had a range of only four miles, and was too large to be easily carried. This time, the lower officials wanted to improve the Frankie cannon, first, to reduce its size, and second, to extend its range to about the same as that of the Hongyi cannon. ”

Listening to Xu Guangqi's words, Sun Chengzong was completely stunned.
