The artillery has had a very powerful killing effect since its birth. It can be regarded as the most powerful type of firearms. It has developed many branches in the future world. In the end, it has achieved an invincible golden body, and its descendants have flourished and flourished. It is an important weapon for the country.

However, these days, there are still many restrictions on the use of artillery. It is precisely because of these restrictions that major armies during this period have reserved their use of firearms. Although the firearms are powerful, they are also restricted, so cold weapons are still popular.

The most troublesome thing for soldiers is the word "fried".

These two words, from China, which first used artillery to European countries, from the birth of artillery to modern times, have always been a spell that threatens all soldiers, a sword of Damocles hanging on the heads of both enemies and us.

It is not terrible to have a musket blow-off. It often only hurts one person. If you are really lucky, two or three are also possible, but the scale will definitely not be too large. Compared with the cannon blow-off, it is really a bodhisattva's heart.

China lacks copper, so the cannons are basically iron cannons. If they are copper cannons, they are relatively strong. If the cannons explode, they usually have a hole on the cannon and will not be split.

And iron cannons are really a tragedy, and the Ming Dynasty was even more of a tragedy, lacking money and copper, and the emperor could not help but turn the copper cannons into copper coins.

It is no exaggeration to say that more than 97% of the current artillery artillery of the Ming army are iron cannons, and a few copper cannons are always ready to be melted into copper coins.

What's even more tragic is that in this cold and cold environment, the extreme outside coldness reduces the temperature of the iron cannon itself to a very dangerous number. The iron has good thermal conductivity, and the speed is first-class in both heating and heat dissipation, and the cold cannon body here.

Once the gun is shot here, the gun body is heated rapidly, and the gun body continues to heat up, and the gun body is shot again - bomb!!!

It's aborted.

Generally speaking, it is time to retreat to dissipate heat when fighting three guns. When Xiao Ruxun used the tactics of big guns, he learned the method of three shooting and divided all the guns into three teams. After the first team was killed, he retreated to dissipate heat, and the second team continued to move, and after the second team fought the third team, he continued to move.

Judging from the speed of launching, the heat dissipation effect is still good, so it can maintain a long-term shooting. Generally speaking, Xiao Ruxun does not allow soldiers to use water to accelerate heat dissipation. Iron smelting technology and cannon casting technology are not very smart these days. The hot cannon body here is sprinkled on the other side, hissing~

A gust of water vapor is indeed beautiful, but who knows whether the cannon body will deform?

Everyone knows the principle of thermal expansion and contraction. Your heat dissipation this time is fast, and the next shot may cause an explosion and everyone will die.

But it is obvious that the Ming army gunners who were anxious to fire the Mongols did not care about this, or they thought that the cold weather could accelerate the heat dissipation of the artillery, so they used artillery more unscrupulously. But can the iron of the Ming Dynasty compare with modern steel?

When Wei Yunzhen rode his horse down the city tower, he saw several broken corpses falling from the city tower, and a broken leg. He frowned and immediately got off the horse and rushed up the city wall. When he saw that even though he had seen strong winds and waves, he closed his eyes and shouted in pain, and immediately ordered.

"Take all these people away immediately! Use sandbags to fill the gap here, and then transport a cannon over! Pay attention to the heat dissipation of the cannon! Pay attention to the heat dissipation of the cannon! At most three cannons, you must change the cannons! At most three cannons! You must change the cannons!"

Immediately, a messenger ran all over the city walls and passed Wei Yunzhen's orders to the ears of every Ming army gunner, but it seemed that it was too late.

The explosion on the Ming army's city wall greatly boosted the Mongolian people. The Mongolians actually organized another charge in a very short period of time, and the pressure on the Ming army on the city wall increased greatly.

"Open fire! Send arrows! Roll the wood and stones, don't stop!"

Wei Yunzhen personally directed the battle on the city wall. He drew out his own sword and roared angrily.

The Ming army drums rumbled on the top of the city, and the governor personally directed the battle to give the Ming army some peace of mind. The panic caused by the explosion just now gradually disappeared.

The Ming soldiers who survived on the city immediately launched a counterattack against the Mongols. Arrows were like rain and artillery roared one after another. The Mongols' attack was once again blocked.

However, the Mongols were not only cavalry. The Mongols who plundered most of the castles in Datong not only had artillery guns, but also catapults and bed crossbows. Just in front of Wei Yunzhen, two soldiers were pierced into a string by a flying bed crossbow and nailed to the city tower behind him.

His eyes were filled with tears and he looked at the two soldiers who were dying with eyes wide open, and he was breathing heavily.

"Futai! It's too dangerous here! Beilu not only has artillery, but also bed crossbows and catapults. It's too dangerous here! You should leave immediately!"

The guard of Yanmen Pass hurriedly ran to Wei Yunzhen and shouted loudly.

"The soldiers are fighting bloody! But I want to escape at the last minute? I can't stand with the soldiers. Why should I use my life? Although I am weak, I am not afraid of death!"

Old Wei refused and continued to nail it to the city tower.

Lao Wei was a civil servant, a civil servant in his bones. Of course, he had his own selfishness, just like when Zhang Juzheng went home for burial after his death. At that time, officials in Jingzhou were greedy for the power of the Zhang family and rushed to pay their respects. He was the only one who didn't go, and others thought he was stupid, but it was not.

Because he had already seen that once Zhang Juzheng died, his power and his followers would be destroyed sooner or later. Although he had a little idea of ​​being the only one at that time, it would definitely not last long.

Therefore, he, a small official, refused to pay his respects to the possibility of being retaliated by the Zhang family, and even beat the servant who advised him to pay his respects, which made him famous for a while.

He was born in a Jinshi in the third grade and was unable to be elected as a Shujishi. He could only observe politics and then release the country. According to historical rules, his future was very limited, and he might even be trapped in the sixth and seventh ranks for the rest of his life.

But he did not accept his fate, seized the opportunity, resisted the fear of the power of the Zhang family in his heart, and successfully entered the eyes of the anti-Zhang Juzheng force group in the court, and was promoted back to the capital and served as the censor.

During his tenure as the censor, he kept firing against Zhang Juzheng's remaining forces. It cannot be said that he opposed Zhang Juzheng's reform, but he was indeed standing opposite Zhang Juzheng.

Moreover, at that time, he didn't even have the qualification to oppose it, he was just a cannon fodder. Even so, he was deeply afraid of Zhang Siwei, Shen Shixing and others.

You can't just say that he was a rude minister just because he was praised by Hai Rui. He has his own selfish intentions and is also doing things to promote his own power. He bluntly stated that Zhang Juzheng's various faults were not because of justice and ideas in his heart, but for power and status.

The reason why he came to Shanxi to be a governor was to defend Zhao Nanxing, the future boss of the Donglin Party, and guilty other forces in the court and was released from Shanxi as a governor.
