Twelve o'clock in Chang 'an is very popular recently, because it restores everything in the Tang Dynasty. So, was there such a thing as fuhuolei in the Tang Dynasty? What's the use? After my investigation, I found that the fuhuolei did not exist, and it was compiled by the author, but the author created it based on gunpowder. When I was in Tang Gaozong, I lived forever for an alchemist.

Therefore, many experienced alchemists in the Tang Dynasty, when mixing saltpeter, sulfur and Gleditsia sinensis together, suddenly exploded and produced flames, so they accidentally made a formal method of making gunpowder. But it was not used in military affairs at first, but in festivals, some acrobats made fireworks and firecrackers to make the festivals more lively.

Moreover, this kind of gunpowder was not ready at that time, and it could not hurt people at all. At that time, no one thought it could be used in war. Therefore, fuhuolei was the gunpowder of the Tang Dynasty, but it was a little more advanced than the Tang Dynasty. In the author's words, it is mixed with white phosphorus, sawdust and gunpowder, which will explode once it touches stone grease. This is entirely a gunpowder copy in the late Song Dynasty. In the play, it is mainly used to blow up Chang 'an and attack the enemy in border operations.

It will burn and shock a large area of enemies. So, to sum up, there was no ambush in the Tang Dynasty. There was only gunpowder in the Tang Dynasty, which would not be used in the military. The ambush is an imitation of gunpowder used in the Song Dynasty. It can be used to repel enemies and defend the country. It took only a dozen people to hold the things in the city, and the power was very rapid. Once there is a fire, even water cannot put it out. Hope to adopt yo.
