Wang Feng was doing a demonstration, while teaching by hand, it took an hour, and everyone finally came up with a thunder~~ mercury acid, but at this time, the thunder~~ mercury acid is violent, and it will explode if it is hit by a slight impact, and it cannot be used directly, so it must be passivated.

In a variety of passivation materials such as wax, diatomaceous earth and oil, the best effect is wax, Wang Feng asked people to take some wax over, but this proportion is exquisite, too small to achieve a passivation effect, too large and difficult to detonate, this time Wang Feng did not let people participate, but groped by himself, accompanied by scattered explosions, after repeated trials, twenty minutes later got the appropriate proportion.

It is not difficult to make the thunder~~ tube, put the thunder~~ mercury acid into a small tube rolled up with thick paper, and then connect the lead.

Next, the fuse is delayed, the point of this step is to apply flammable gunpowder to the part where the fuse rubs against the main body of the grenade, pull the buckle through guò, ignite the fuse with friction, burn to the end to detonate the thunder~~ tube, and then detonate the gunpowder in the grenade.

The basic principle of grenades, including artillery shells, is to detonate a high-power blunt explosive with a small dose of sensitive explosive.

Almost close to the evening, Wang Feng finally made the first grenade in Chinese history, compared with the standard grenade of the People's Liberation Army, except for the rougher, all aspects are exactly the same, the top is a pitch-black iron hoop, which is filled with gunpowder, a small amount of gravel and thunder ~~ tube, the lead is through the hole drilled in the wooden handle connected to the bottom of the pull ring, the pull ring has the effect of detonation, but also as a usual insurance, must use a certain amount of strength to pull away.

"Wang Feng, this is a grenade? I don't think it's anything. Hong Xuanjiao looked at Wang Feng's hand with curiosity.

"Oh?" Wang Feng smiled disappreciatively: "Sister Xuanjiao, I am the first person in China to make a grenade, do you want to be the first person to throw a grenade?" You come here, it's very simple, hold the wooden handle with your right hand and put it to your mouth, bite and pull the ring and throw it immediately, try? ”

Wang Feng handed the grenade over, his eyes seemed to be smiling, to be honest, Hong Xuanjiao didn't have much confidence in this ugly guy, but Wang Feng's gaze made her very unhappy, so she turned her heart sideways, stretched out her hand to take it, faced the open place, and bit down the pull ring suddenly, "Zizizi!" A puff of green smoke came out.

Hong Xuanjiao witnessed the birth of the grenade, which was full of gunpowder and thunder~~ tubes, which could kill people in any case, and now, it was still smoking at his mouth!

She is a woman after all, although she is ambitious and has killed many people, but there is a weak side in her nature, she can't help but panic in her heart, her hand is weak, and the grenade falls to the ground, which makes her mind blank for a moment, and her heart is over!

Everyone was also stunned, "Grass you mother!" Wang Feng scolded angrily, flew to knock Hong Xuanjiao down, and stretched out his foot to barely hook the grenade into the distance!

But after all, it was a hook, not a kick, and I heard a loud bang, and the grenade exploded about two feet around me!

Generally speaking, the killing radius of modern grenades is six to seven meters, and the grenades made by Wang Feng are slightly less powerful because they use black gunpowder, but they also have a killing radius of four to five meters.

'Well done! Wang Feng gave himself a sigh of relief, he was very satisfied with the power of the grenade!

"Wang Feng, get up quickly, press me!" At this time, Hong Xuanjiao shouted dissatisfiedly, with a little tremor in her voice, obviously frightened.

Wang Feng said in a strange voice: "I said Hong Xuanjiao, if you want to die, don't commit suicide in my camp, I didn't provoke you, right?" ”

"What did you say?" Hong Xuanjiao suddenly said angrily: "I have never thrown a grenade, but you just let me vote, and I said that you deliberately hurt me!" Get up! ”

To be honest, Wang Feng didn't think about it at all, and below was Hong Xuanjiao's fragrant body, which was simply a supreme enjoyment, so he lowered his voice and smiled: "Sister Xuanjiao, I saved your life, not only are you not grateful but you also slander me, you say, how can there be a woman like you?" People say that a husband and wife are a hundred days a day, how can I be willing to harm you? By the way, have you been vomiting and nausea during this time? It's not unusual to say what happens to men and women, and it's not uncommon for a shot to hit, if you have my child in your belly, isn't it one corpse and two lives? I'm even more reluctant, you say? ”

Originally, Hong Xuanjiao already felt a little guilty about Wang Feng, but when she heard the latter words, she immediately became angry and said, "Who is husband and wife with you?" Get lost! Go down! As he spoke, he pinched Wang Feng's waist and eyes with his backhand!

"Ouch!" Wang Feng screamed strangely, and hurriedly propped himself up, but took advantage of the situation to dig on Hong Xuanjiao's soft chest, and then turned it over!

In an instant, everyone was dumbfounded, and some even rubbed their eyes, Wang Feng dared to eat Hong Xuanjiao's tofu openly? You know, she is Xiao Wangniang, the surviving person of Xiao Chaogui, the king of the West!

Looking at Hong Xuanjiao again, although her face was flushed, she was not ashamed and indignant, but she looked angry and annoyed, combined with the conversation and laughter of the two before, this made people have to think about it in that direction, especially the eyes of those female soldiers looking at Hong Xuanjiao are different!

Hong Xuanjiao has a feeling that she wants to go crazy, but she can't have a fight with Wang Feng, she can't shout that you should be guilty of touching the old lady's breasts, right? can only suffer a dumb loss.

After the full chest rose and fell violently, Hong Xuanjiao blushed and said coldly: "The grenade is really extraordinary, Wang Feng, you can do as much as you can in the past five days, and I will find a way to get some more materials for you!" After saying that, he didn't even say hello, and walked out quickly.

The female soldiers also looked at Wang Feng strangely, and followed closely.

Lu Dayou hurriedly leaned up, and said with a smile: "Master Shuai, I, Lu Dayou, admire you like the water of the Yangtze River, you actually took advantage of Xiao Wangniang, amazing!" ”

"Oh?" Wang Feng said casually: "How can I take advantage?" I'm saving people, it's a last resort, you kid don't spread rumors, I'll give you a task, before dawn tomorrow, you have to take your brothers to make two hundred empty grenades, don't fill with mines~~ Tube gunpowder, starting tomorrow, the whole army will practice bombing. ”

"Huh?" The faces of nearly ten people led by Lu Dayou were bitter, two hundred in one night, equivalent to twenty per person, especially after the meal, there was a two-hour training mission that could not be shaken, which meant that I didn't want to sleep tonight.

One after another, all eyes were cast on Lu Dayou with unkindness, and it was his cheap mouth that attracted the revenge of the commander!

"I don't care what method you use, I must see it tomorrow morning, two hundred, not one less!" After putting aside the reminder, Wang Feng put his hand behind his back and slowly paced towards the front of the camp.
