The so-called dog bomb is to wrap a ball of black powder in aluminum foil or soft cigarette box, tamp it tightly, and explode when it is smashed on the ground.

Because Chongqing is a mountain city with many dense forests, there were wild dogs and jackals on the mountains of his hometown in the seventies and eighties, so basically every household was equipped with muskets and "dog bombs".

With years of continuous slaughter by the villagers, the wild dog jackal slowly became extinct, and by the nineties it was basically invisible, and the musket gunpowder of every household in the village was also confiscated by the government, but the method of making dog bombs was retained.

Although there is no large amount of gunpowder, but people always have a way, some fun-loving young people will buy a lot of firecrackers, and then pour out the gunpowder in the firecrackers little by little, pour a small bag to make a dog bomb, experience the feeling of playing with bombs.

Until now, there is a kind of firecracker for children to play with, that is, the principle of thunderbolts, which has no fuse and explodes when smashed on the ground.

If the masters of the Tang Sect knew that their big killer weapon, the thunderbolt, would have become a child's toy in the next generation, I don't know how they would feel.

"You haven't thought of using a fuse to detonate gunpowder?" Ouyang Fei asked in surprise.

Tang Wuying was stunned when he heard this, and asked rhetorically, "What is the fuse?"

After Ouyang Fei finished speaking, he remembered that the real fuse rope only appeared in the Southern Song Dynasty, and it was still three or four hundred years away!

"Okay! I'll teach you how to make your first weapon of destruction today, and if this weapon is made, the city gate will not be an obstacle for you in the future, and if there is enough gunpowder, even the city wall can be easily destroyed. ”

Tang Wuying's eyes lit up, what did my brother mean that this thing was made, and even the city gate and city wall could be exploded? You don't have to play so big at once, right? Shouldn't it be gradual? But...... It's so exciting, I love it.

"Go find some linen cloth and empty wine jars, and some gunpowder and vinegar, and if you can't get gunpowder for a while, get some stone, stone, sulfur, and charcoal. ”

Tang Wuying wrote them down one by one, he naturally knew why Ouyang Fei wanted those three things, because they were the formula of gunpowder.

It took most of the day, Tang Wuying took a vote of Tang Sect disciples to find all the things, and the brothers were busy in the camp tent in full swing, and there was no one else next to them except for the Tang Sect disciples.

Everyone knew that Ouyang Fei was teaching Tang Wuying the secret method of making weapons, and the people in the rivers and lakes were very particular about this aspect.

Without the permission of the parties, they must not approach without permission, otherwise they will be suspected of stealing teachers, which is a big taboo in the rivers and lakes.

I saw that Ouyang Fei first boiled a pot of vinegar, and when the vinegar boiled, he put some linen cloth into the vinegar and boiled.

After boiling, the linen cloth is taken out to dry, cut into uniform strips, and then the prepared black powder is evenly sprinkled on the linen strips, and finally the linen strips sprinkled with gunpowder are twisted up and rolled into a rope, and the gunpowder is naturally wrapped inside.

"Okay, this is the fuse, let's try the effect first. Ouyang Fei used scissors to cut off a two-inch fuse rope, and used the lit incense stick to the end of the fuse.

"Sneer......"

The fuse soon burst into flames, burning all the way, the two-inch fuse burned for more than ten seconds, Ouyang Fei nodded with satisfaction, and said: "Very good, successful, with this thing, many big killers can be made." ”

Tang Wuying was still a little foggy, and said puzzledly: "Brother, what is the use of this fuse rope?"

Ouyang Fei smiled slightly and said, "You look at it, bring the empty wine jar." ”

When the Tang Sect disciple on the side heard this, he immediately took a ten-pound empty wine jar and handed it to Ouyang Fei, Ouyang Fei looked at the big wine jar, glanced at the Tang Sect disciple speechlessly, and said with a wry smile: "Brother, let's change to a small one! ”

When the Tang Sect disciple heard this, he hurriedly changed a small wine bottle, three catties of the kind, Ouyang Fei took it, and began to use a wooden spoon to scoop the black powder into it, and when it was half a small time, he tamped the gunpowder with a wooden rod wrapped in a thick cloth, and then continued to load.

Ouyang Fei repeatedly filled the gunpowder into the wine bottle and tamped it, and after filling most of the jar, he inserted a one-foot-long fuse rope into it, and then filled the wine bottle to the full, which was flush with the mouth of the bottle.

Finally, cover the tarpaulin, make a hole in the tarpaulin, let the fuse rope come out, tighten the oil and tie it up, and a simple bomb is made.

One pound in the Tang Dynasty was about 660 grams, and these three catties of gunpowder were nearly two kilograms in later generations, and the black powder was compacted and placed in a closed and narrow utensil such as a clay pot, and the power of the explosion was quite powerful.

The explosive power of black powder is 0.6 to 1 compared with TNT, and the power of one kilogram of TNT is equivalent to twenty grenades.

Ouyang Fei held the wine bottle in his hand and said to Tang Wuying complacently: "Wuying, do you know how powerful this wine bottle is?"

Tang Wuying asked tentatively, "How can it be stronger than palm thunder, right?"

Ouyang Fei pursed his lips disdainfully, and said, "Palm thunder, twenty palm thunders exploding together is about the same, just this one wine bottle is enough to blow a house with a radius of five zhang into ruins." ”

"If you add some fine iron beads or even gravel to it, and explode in an open place, within a radius of ten zhang, chickens and dogs will not be left, and within twenty zhang, nine will die. ”

"What, so powerful?" Tang Wuying was really taken aback this time, and the Tang Sect disciples next to him were also surprised.

"Let's go! Let's go outside the city. Ouyang Fei held the earth bomb in his hand, got out of the camp tent, and went straight out of the city, Tang Wuying and the others hurriedly followed.

When many people saw them going outside the camp, they all came up curiously to ask what the situation was, and after listening to the explanation of the Tang Sect disciples, they followed with great interest.

In the end, even Fang Qian, Li Chengen, Yan Wangqing and others were alarmed, and everyone came out to follow Ouyang Fei, and a group of hundreds of people went out of the city.

The camp was not far from Chaoxi Gate, and everyone quickly went out of the city, and when they arrived at the place where the heavy machine gun was tested last time, Ouyang Fei still found a hill, dug a shallow pit and put the earth bomb in it, and then said to everyone: "Everyone withdraw fifty zhang away, otherwise it is easy to be injured by the broken tiles that fly out." ”

Although everyone felt that their martial arts were strong and they could avoid it even if they couldn't stop it, no one was asking for trouble.

After everyone withdrew fifty zhang, Ouyang Fei asked Tang Wuying to light the fuse with his own hands.

"Shem!"

As soon as the fuse was lit, Ouyang Fei immediately performed light skills, pulled Tang Wuying and flew away, and ran to the place where everyone gathered.

Everyone waited for more than ten breaths, but there was still no movement, and they looked at Ouyang Fei suspiciously.

"Don't worry, don't worry, this time for safety, I set the explosion time to be relatively long, and in the future, Wuying can set the time according to the actual situation. ”

Tang Wuying nodded clearly, the time of this explosion was naturally controlled by the length of the fuse, and he still understood this.

"Boom"

Thirty seconds later, the earth bomb exploded.
