For capable people, Sun Chengzong is very respectful, and Xu Guangqi, who can manufacture advanced firearms, naturally has great respect, and does not regard the other party as a craftsman at all.

It's just that Xu Guangqi was a little surprised, he has been here all this time, and he can be said to have no idea about the things outside. Although I don't know when this Lord Sun became a cabinet scholar, out of the duty of a civil official, he still bowed to Sun Chengzong and said respectfully: "The lower official has seen Lord Sun." ”

"Lord Xu, you're welcome!" Sun Chengzong hurriedly avoided Xu Guangqi's salute and pulled Xu Guangqi with a smile. "Let's talk about this cannon!"

"Well, so be it! I'll let someone shoot it for Master Sun first! Waving to a few people in the distance, Xu Guangqi said with a smile.

Looking at the skillful operation of the cannons by those people, Sun Chengzong looked meticulously, there were many artillery pieces equipped in the Ming army, whether it was a fire gun or a tiger squat cannon, there were many types. Now this improved red-coated cannon, Sun Chengzong has seen it for the first time, although the volume is smaller than the previous red-coated cannon, and the barrel is shorter, but it looks more stable.

The red-coat cannon was made by Europeans in the 16th century, and it was not introduced to the Ming Dynasty for a long time, and it is a relatively new type of weapon. The new red-coated cannon organized by Xu Guangqi has added a lot of Xu Guangqi's research results. Compared to the Europeans, the redcoat cannon is more powerful, but it is much smaller.

Seeing Sun Chengzong's appearance, Xu Guangqi smiled with satisfaction, what he studied was approved by others, and it was a matter of pride. Seeing that the person who operated the cannon signaled to himself, Xu Guangqi pulled the Emperor of the Apocalypse and Sun Chengzong to withdraw far away.

With a huge sound of artillery bombardment, a huge black iron ball quickly flew out, and as for the landing point, neither the Emperor of the Apocalypse nor Sun Chengzong saw it, because it was too far away.

"Lord Xu, the range of this cannon?" Sun Chengzong was obviously shocked, his eyes were full of disbelief, and he looked straight at the direction where the cannonball was fired, and said with some stumbling.

"The range of this cannon has been measured by someone from the humble position, and it is about eight miles." Xu Guangqi didn't feel that there was anything wrong with Sun Chengzong's attitude, the Ming Dynasty made its own firecracker, and the range was only three miles away. In comparison, this red-coated cannon is very powerful.

The key to measuring heavy artillery such as the redcoat cannon is the firing range. With such a range, many other things can be ignored, and if such a cannon is used to attack the city, a few cannons will go down, and a large part of the city wall will definitely collapse.

The disadvantages of the redcoat cannon are also another key factor in considering a type of cannon, that is, the rate of fire. This kind of red-coated cannon, although the range is sufficient, but the rate of fire is not satisfactory. Ten shells in a quarter of an hour is a good thing, not counting the time to cool the barrel. According to the calculation of the time of the later generations, that is, one shot in two minutes, this speed has to be said to be too slow.

Thinking back to the advantages and disadvantages of the red-coated cannon, the Emperor of the Apocalypse has nothing to do, this kind of front-loading cannon, if you want to increase the rate of fire, it is tantamount to a fool's dream. This is also the reason why the Emperor of the Apocalypse only asked Xu Guangqi to make a hundred of these cannons, which is really too expensive, but the actual effect is not large. With these 100 cannons, it can be said that it is enough for a period of time, mainly to put it at the head of the city to defend the city. As for those who want to fight in the field, it is more necessary to prepare a small cannon with a very high rate of fire and easy to carry.

An army of 10,000 people carrying 300 small cannons does not take up too much manpower and material resources, but it can exert great power in battle. As long as the rate of fire is sufficient, then the shells are overwhelming.

At this time, the speed of the Eight Banners cavalry and the Mongolian cavalry was very fast, and they were already able to run a long distance in two minutes, and the interval between the red-coated cannons was too long, and there was no use in field battles at all.

Just when the Emperor of the Apocalypse was pondering alone, Sun Chengzong and Xu Guangqi already knew about it, and the two came to the side of the Emperor of the Apocalypse hand in hand.

"How? These things aren't bad, right? Glancing at Sun Chengzong with a smile, the Emperor of the Apocalypse asked knowingly.

"This is really a weapon of attack, what a good thing!" Sun Chengzong's heart was quite emotional, I really don't know where this young emperor found this Lord Xu, this is really the treasure of the country. If all the children of the Shenji Battalion use such guns, and every army is equipped with such artillery, then the combat effectiveness of the Ming army can be greatly improved!

"Your Majesty, are these weapons going to be equipped with the troops?" Sun Chengzong can be said to have a very good understanding of the situation of the Ming Dynasty at this time, and his heart suddenly became hot, and he looked at the Emperor of the Apocalypse with anticipation.

The Emperor of the Apocalypse naturally thought about this matter, but just after thinking about it, he quickly dispelled this idea. Good things must be handed over to good people, otherwise not only can they not be helped, but they will become a weapon to hurt themselves.

In the original history, the Ming army was also equipped with a large number of red-coated cannons, but what happened later? The red-clothed cannon became a sharp weapon in the hands of Hou Jin, attacking the city of the Ming Dynasty, and a few cannons could blast it open.

Once this kind of cannon is pulled out at this time, Houjin and those enemies of the Ming Dynasty will soon be able to use it. If it is being copied, the consequences can be serious. After all, this kind of cannon is not good at defending cities, but at fortifying fortifications, and it can't take a few hits in a fortified city.

The reason why the Emperor of the Apocalypse studied these things so secretly was so that they would not be passed on, and the Emperor of the Apocalypse would rather keep them all in the warehouse before he had troops that he could really master.

Naturally, the Emperor of the Apocalypse would not tell Sun Chengzong about these things, and after glancing at Sun Chengzong who was full of anticipation, the Emperor of the Apocalypse said with a smile: "I know Aiqing's mood, I have my own arrangements for these things, and Aiqing will know when the time comes." ”

Sun Chengzong's mouth was a little bitter, and when he asked what he said just now, he felt that it was inappropriate. At this time, Daming is not only an external crisis, but also those people inside, who do everything for the sake of interests. You must beware of them, how can these things be taken out so easily?

Sun Chengzong's expression was a little depressed, but suddenly he felt as if he had drilled the tip of the horns, and the young man in front of him, since he had made these things quietly, he must have his own plans. Sun Chengzong believes that this Heavenly Apocalypse Master must be more anxious than himself, what's wrong with him? Where has the Qi cultivation kung fu been all along? Not as good as a teenager.
