Sun Chengzong respects all the capable people very much, and naturally respects Xu Guangqi, who can make advanced firearms, and has no intention of treating the other party as a craftsman.

However, Xu Guangqi was a little surprised. He had been here for a while and could not tell at all about the outside. Although he didn't know when Lord Sun became a Grand Secretary of the Cabinet, he still bowed to Sun Chengzong for his duty as a civil servant and said respectfully: "The official has met Lord Sun."

"Mr. Xu, you're polite!" Sun Chengzong hurriedly avoided Xu Guangqi's greeting and grabbed Xu Guangqi with a smile. "Let's talk about this kind of cannon!"

"Well, let's do it! I'll have someone give me a shot to see Lord Sun first!" He waved to the people in the distance, and Xu Guangqi said with a smile.

Seeing those people skillfully operating cannons, Sun Chengzong looked meticulously. There were many cannons equipped in the Ming army, whether it was muskets or tiger squat cannons, there were many types. This was the first time that Sun Chengzong saw this improved red-clothed cannon. Although the size was smaller than the previous red-clothed cannon and the barrel was shorter, it looked more stable.

The red-clothed cannon was made by Europeans in the 16th century. It was not long before it was introduced to the Ming Dynasty and was a relatively new weapon. This new type of red-clothed cannon made by Xu Guangqi organization has added a lot of Xu Guangqi's research results. Compared with the Europeans' red-clothed cannon, it is much smaller in size.

Seeing Sun Chengzong's appearance, Xu Guangqi smiled with satisfaction. The things he studied were approved by others, which was something worthy of pride. Seeing that the person who was fucking the cannon signaled him, Xu Guangqi pulled Emperor Tianqi and Sun Chengzong out far away.

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

"Mr. 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 shells were shot out, and he stuttered a little.

"The range of this cannon has been sent to measure, about eight miles." Xu Guangqi did not think anything was wrong with Sun Chengzong's attitude. The range of the fire guns he made in the Ming Dynasty was only three miles away. In comparison, this red-clothed cannon is very powerful.

The key to measuring heavy cannons like red cannons is range. With such a range, many other things can be ignored. If you use such cannons to attack the city, if you go down a few cannons, the city wall will definitely collapse.

The disadvantage of the red-clothed cannon is another key factor in considering a kind of cannon, which is the rate of fire. Although this red-clothed cannon has a sufficient range, its rate of fire is not satisfactory. It is very good to shoot ten shells in a quarter of an hour, which is not the time to cool the barrel. According to the large time in later generations, it is only one shot in two minutes. This speed has to be said to be too slow.

Thinking back on the advantages and disadvantages of the red-clothed cannon, Emperor Aoqi had no choice. It was a fool to increase the rate of fire in this kind of front-loading cannon. This is also the reason why Emperor Aoqi only asked Xu Guangqi to make one hundred such cannons. It was really too much, but the actual effect was not great. With these hundred cannons, it can be said that they were enough for a period of time, mainly to guard the city at the top of the city. As for wanting to fight in the field, you have to prepare a small cannon with a very high rate of fire and easy to carry.

An army of ten thousand people carries three hundred cannons, which will not occupy too much manpower and material resources, but it can exert great power during battle. As long as the rate of fire is sufficient, the shells will be overwhelming.

At this time, the Eight Banners Cavalry and Mongolian Cavalry were both very fast, and they could run far away in two minutes. The red-clothed cannons had too long intervals, and field battles were useless.

Just as Emperor Tianqi was meditating alone, Sun Chengzong and Xu Guangqi had almost understood each other, and they came to Emperor Tianqi together.

"How is it? These things are not bad, right?" Emperor Tianqi asked knowingly.

"This is really a weapon for attack, it's such a good thing!" Sun Chengzong was quite moved. He really didn't know where the young emperor found this Lord Xu. This is really a treasure of the country. If all the children of Shenji Camp used such guns and each army was equipped with such artillery, the combat effectiveness of the Ming army could be greatly improved!

"Your Majesty, do you need to be equipped with these weapons to the army?" Sun Chengzong was very familiar with the situation at the Ming Dynasty at this time, and his heart suddenly became hot, and he looked at Emperor Tianqi with anticipation.

Emperor Tianqi naturally thought about this matter, but just thinking about it, he quickly gave up this idea. Good things must be handed over to good people, otherwise they will not only not become help, but will instead become a weapon to hurt themselves.

In the original history, the Ming army was equipped with a large number of red-clothed cannons, but what happened later? The red-clothed cannons became a powerful weapon in the hands of the Later Jin Dynasty. They could attack the cities of the Ming Dynasty and bombard them with just a few cannons.

Once this cannon is pulled out at this time, the Later Jin and the enemies of the Ming Dynasty will soon be used. If they are copied, the consequences will be serious. After all, this cannon is not good at defending the city, but is good at attacking the toughest, and it can't stand a few strokes in a solid city.

The reason why Emperor Apocalypse studied these things so secretly was to not spread it. Before there was a force that he could truly master, Emperor Apocalypse would rather have all these things in the warehouse.

Emperor Tianqi naturally would not tell Sun Chengzong about these things. He glanced at Sun Chengzong with a look of anticipation. Emperor Tianqi smiled and said, "I know my dear mood. I have my own arrangements for these things. I will know then."

Sun Chengzong's mouth was a little bitter. He asked what he said just now, and he felt that it was inappropriate. At this time, the Ming Dynasty was not only an external crisis, but also an internal person who could do everything for the sake of profit. Beware of them, how can these things be taken out easily?

Sun Chengzong looked a little depressed, but suddenly he felt that he was getting stuck in the slightest. Since the young emperor in front of him made these things silently, he must have his own plans. Sun Chengzong believed that this Tianqi Master must be more anxious than him. What's wrong with him? Where has the skills of qi cultivation been gone? He is not as good as a young man in his teenage years.
