We must mention the firearms of the Ming Dynasty.

Zhu Di, the Emperor of Yongle who was fierce in governing the country and admiring martial arts, was even more in love with fire instruments.

Wang Jiu's investment in the Ordnance Division among the Jinyiwei was completely free of cost, and the development and use of firearms was the only one in the world in the development and use of firearms!

There are two main categories of firearms nowadays: the first category is firearms and bird guns placed with hand-held points. The shape and caliber are large. Generally, the barrel is loaded with lead bullets and iron bullets, and its range is dozens of steps to 200 steps. At that time, the manufacture of firearms (gunpowder rockets) was quite exquisite and had a wide variety of styles.

According to historical records such as "Fire Dragon Artifact Formation" and "Wu Beizhi", the types of rockets used here include single-shot rockets, multiple volley gunpowder arrows, multiple gunpowder cartridge parallel rockets, winged rockets, multi-stage rockets, etc. There are dozens of rocket varieties!

The second type is the caliber and body-shaped large artillery fired on the rack. Most of the barrels are loaded with stone, lead, iron, etc., commonly known as "solid bullets", and a few are loaded with explosive balls, with a range of hundreds of steps to two or three miles away. They are mainly used for defending villages and siege cities, and are also used for field battles, water wars and naval battles. The Ming Empire army has generally equipped firearms, and the main weapons of war have turned to the use of firearms.

Now equipped with the "Shenji Camp", this independent artillery system is the best in countries around the world.

When Zheng He went to the West, Emperor Yongle Zhu Di even equipped the fleet with various firearms. The "Shen Ji Camp" naturally equipped Zheng He with a team and equipped two bronze cannons that were newly developed by the Jinyi Guard Ordnance Department, weighing only 250 and 60 kilograms and about three feet and six inches long!

The shells are a large lead shell weighing four or five kilograms and hundreds of small lead shells weighing four or five kilograms. All the shells are only more than seven kilograms in total. When used, the cannons are placed on supporting cannon vehicles, which are convenient to move and very suitable for field combat.

It is reported that Emperor Yongle Zhu Di first saw this exquisite bronze cannon, so he wanted to promote it in the army. After he asked how much the cannon cost, he kept silent. Because this bronze cannon has outstanding advantages, strong and excellent heat dissipation, it is actually a good material for making cannon barrels, but the cost is really high, even the Yongle Emperor, who has always been a big deal, can't stand it!

Explosive firearms are already quite developed, and there are two specific categories: one is land mines, with a wide variety, including dozens of stone thunder, ceramic thunder, pig iron thunder, etc.; the other is water mines, including underwater thunder, underwater Dragon King Cannon and Hunjiang Dragon.

According to a large number of historical facts, China is the first country in the world to invent and use the "two thunders".

Zheng He's treasure ship is naturally equipped with mines, and there are quite a lot of them!

Zheng He went from the wharf to the Ceylon Mountain Palace, and among the three thousand soldiers he led, the team of Shenji Camp and two bronze cannons also came with the army.

The people of Shenji Camp were very good. They fired two cannons just now when the sky was dawn. The first cannon fell several feet into the city tower in front of the palace gate, but it smashed the bluestone floor to pieces of gravel flying around more than ten feet. If someone was there, there would be no second result except "destroying ashes".

The first shot is more accurate, while the second shot is very accurate, just in the city gate, and the ancient red city gate "creaked" opened a hole several feet square...

The artillery fire is temporarily suspended.

The city gate was slowly pushed open, and several black figures flashed; and on the battlements, there were even blood-stained faces on the Yichen face, and he signaled that all the defenders on the battlements had been cleared!
