A small bamboo tube, filled with up to half a catty of so-called "gunpowder", after ignition, it produced such a power, the sound was loud, the fragments of the bamboo tube flew everywhere, and even some gravel flew up. Except for Yang Xi, everyone else turned pale with fright.

It's terrifying, I knew to stand far away.

Wang Xuan, the captain who had just gone to ignite, was even more frightened, if he was still on the side when the explosion occurred, he didn't know what he would be blown up into.

The gunpowder made by the simple ratio had such power, Yang Xi was full of joy that could not be concealed, and shouted at the stunned generals on the side: "Haha, generals, you understand what this thing is for now, right?!" ”

"Marshal, it seems that it can be used to blow up the city walls and city gates!" Gao Shi reacted the fastest, and immediately picked up Yang Xi's words, "It's very useful when attacking the city and killing the enemy!"

"That's right," Yang Xi glanced at Gao Shi who was standing beside him, and then looked at the other generals who were still shocked, and said happily: "This is called gunpowder, and the powder that can be ignited by fire is very powerful. The Taoist priests of alchemy already knew this principle, but no one thought of using it to make weapons. If gunpowder is widely used in the military, it will definitely greatly improve the combat effectiveness of our Datang army. Presumably, you still don't fully understand the huge destructive power and lethality of gunpowder, so Ben Shuai will show you again!"

The generals all knew that gunpowder was made according to Yang Xi's recipe, and this demonstration just now had made them see the power of gunpowder, and their admiration for Yang Xi had risen to a new level. It's not easy to make such a powerful thing!

Of course, they also wanted to see how Yang Xi would test and how powerful the gunpowder was!

Yang Xi also immediately ordered the sergeants to take an iron jar filled with about a pound of gunpowder, dig a pit in the mountain, bury the iron can, and expose the end of the opening, still using gunpowder piled up in a line to ignite, or the captain Wang Xuan stepped forward to light it.

Wang Xuan, who had already seen the power generated when gunpowder exploded, cautiously stepped forward and lit it, and immediately ran away.

The powder line burned at a rapid rate, eventually igniting the gunpowder in the can, and then exploding.

In a huge explosion, countless dirt and gravel were blown up, and they flew for a long time, and some flew out and fell far away. At this time, many people realized that the place where they were standing was too close to the explosion site, and a lot of rubble and earth fell from the sky and fell on them. When this happens, many people run away regardless of their image, and many people hold their heads.

Yang Xi was the most prescient, when he ordered Wang Xuan to come forward and light the gunpowder line, he had already taken refuge in a safe place, behind two long pine trees side by side, and the flying earth and gravel fell near the pine trees, and some smashed on the trunks, but did not fall on Yang Xi. It's just that the guards around him were not so lucky, many people were hit, and some were even injured and injured by rubble.

Some of the sergeants standing in the other direction were hit by the rubble because they were too close, and they were in hot pain.

The effect of explosives in the first appearance in human history was still quite terrifying, and hundreds of battle-hardened soldiers were frightened and overwhelmed. Fresh affairs are always prone to special effects when they are not known, and the same sound of thunder will also make people frightened, regardless of whether the person has experienced war or not.

A large cloud of black smoke rose from the blast, but it was quickly blown away by the wind. Yang Xi walked out from behind the pine tree where he was hiding, and walked to the explosion point where there was still smoke, to check the explosion. Obediently, the power of the home-made "bomb" is still quite large, and it even blew up a large crater with a depth and a diameter of several tens of centimeters, and the power is similar to that of a small artillery shell.

The other generals who were shocked also gathered around when they saw Yang Xi approaching to observe, and they were even more surprised when they saw such a big crater left at the explosion site.

"Marshal, the gunpowder you made is really useful, if you put more of it, the city wall can be blown up!" Li Fude, who thought he was Yang Xi's confidant, naturally patted his ass and said, "Marshal, you can make such a powerful weapon, it's really amazing, and the general admires it very much." The last general felt that if gunpowder was used against the rebels' attacks, even if not its great lethality, such a loud noise would frighten the rebels. The marshal made this sharp weapon, why worry about the rebellion? ”

Although Li Fu's tone was a bit flattering, what he said was agreed by many people, if it was really a weapon made of this powerful gunpowder, the lethality and deterrence must be very amazing, just from the fact that the debris that had just splashed out could injure people and the loud noise that surprised these battle-hardened generals.

People were surprised, and the horses were even more so, and the two huge explosions had already frightened the mounts of their generals, and they were neighing there, and if it weren't for the sergeant's desperate pull to pacify them, they might have all run away in shock.

If a large amount of explosives are thrown into the opponent's array during war, the loud sound of the explosion can frighten the opponent's men and horses, even if it does not talk about its own lethality. If a large number of horses are frightened, it is a terrible thing.

"The power of gunpowder Ben Shuai doesn't need to say anything, you will understand when you see it, and then Ben Shuai will order the craftsmen to continue to develop this thing, and make explosive weapons that are convenient and easy to carry and can be used in actual combat," Yang Xi looked at the generals with a smug face, "After a while, Ben Shuai will ask the imperial court to wave troops to attack Shaanxi County, hoping that gunpowder can come in handy in the battle to attack Shaanxi County." ”

It is not difficult to make weapons out of gunpowder, and the simplest weapon that uses gunpowder as a raw material is an explosive pack. If you make an explosive bag with gunpowder, you can wrap a large amount of gunpowder together, ignite it with a fuse, and throw it by hand or with a stone thrower, which will definitely have great lethality to the enemy army, and it will be very effective when attacking or defending a city.

As long as the lead is made, and the length of the lead is used to control the time of the explosion, the primary firearm product can be used in military use immediately. The lead wire is not a high-tech thing, it can be made with the most basic and commonly used things such as gunpowder, paper, twine, etc., and Yang Xi did not feel any difficulty.

The fuze is the most troublesome.

When gunpowder comes out, firearms such as grenades and shells will always be thought out to make them, and these firearms need fuses.

Yang Xi knows how to make a fuse, he is an expert in this area, but without technology and raw materials, it is not easy to make.

But he believed that with the appearance of his special forces in the Tang Dynasty, the era of gunpowder in the war would be greatly advanced.
