I used to watch anti-Japanese dramas, didn't I say that the grenades made in the border area were all blown up with one blow and two petals, which could only scare people and not hurt the little devils, why is this rolling mine so powerful today, it may be the amount of medicine, how much gunpowder can be contained in the grenade? Two or two top the sky, and today I poured about three catties into the clay pot.

If you cast an iron shell, it will be more scary to blow up, but if you blow up two petals at that time, it will be embarrassing, it doesn't matter, let's try it.

Iron nails have to be replaced, otherwise no matter how many blacksmiths are not enough, this thing is used as a killing fragment, without much technical requirements, just use molten iron to cool into small irregular granules, and then study and study how big the particles are.

There is also a troublesome thing, the grenade may not be technical, after all, our technical level is not as good as that made in the border area, and a grenade with the right weight and volume can be thrown for thirty or forty meters. Today's thing, at least more than ten pounds, like a shot put, large in size, strong resistance, how far can it be thrown? Don't throw it out when the time comes, and blow up your feet, and you'll be miserable.

Is there a launcher, depending on this level, most of them can only be ejected, and the structure of the bow and crossbow and trebuchet should not be too technically difficult, but the fuse must be passed, otherwise it will fly into the sky with a bang, and the fire will be extinguished with a pop.

Damn, why did you go back to the fuse material, this thing really doesn't understand.

Ruhua worked hard to write on the side, recording Xue Qing's brainless thoughts.

Xue Qing said whatever she remembered, sometimes she spoke a little faster, and she couldn't keep up with the speed of Ruhua's writing, and she rubbed her stiff fingers and complained: "Your Highness, slow down, slaves and maids can't keep up." ”

Xue Qing shook her dizzy head: "Forget it, it's not early, let's talk about it tomorrow, after eating and washing, you can go down and rest." ”

Ruhua put down her pen and said, "Oh." He walked out quickly and ordered the maid to bring the meal. I was also hungry, so I hid outside the tent and watched Xue Qing eating inside, while stuffing corn and small pieces of barbecue into my mouth.

Seeing Huo Qubing coming over with his head down, Ruhua hurriedly hid the bowl behind her back, wiped her mouth and said, "Master Hou is back, His Royal Highness is having dinner, and I have prepared a leg of mutton for you." ”

Huo Qu was ill, then entered the door, knelt on the soft cushion next to the table, picked up the knife on the table and cut a piece of meat on the leg of mutton, cut it into several pieces and put it in the bowl, picked up a piece of chopsticks and threw it into his mouth, and asked while chewing: "Xue, where did you get the refining method of this weapon?" ”

Xue Qing put down her chopsticks and said, "Does it matter?" ”

Huo Quzhi was stunned, took a sip of the wine cup, swallowed the meat in his mouth and said: "It doesn't matter, the key is what the greatest power of this thing looks like, how to improve it, and how to use it to exert its effect, these are the key." ”

Nonsense, this is not just a slow groping, the old lady must know the same. Huo Quzhi forgot the wine cup on the side of his mouth, and said in a trance: "It is conceivable that it must be the gunpowder that a warlock accidentally discovered, I thought about it, the reason is very simple, the gunpowder ignites quickly and violently, it is packed in a small jar, and it burns quickly, and the jar can't withstand the majestic power, so it will explode." It's the same as the strength we usually exercise, but when it's really time to use it, we use a little bit of the tip of the sword to vent our huge strength, the same reason. ”

Xue Qing nodded, I didn't expect this kid to have a bit of a science student's thinking, that thing seems to be called something like pressure and force area. The ancients also understood that there was no systematic summary, but everyone used a thin blade to cut meat, and no one used a hammer to cut meat slices.

"Let the alchemists continue to study and experiment in order to improve the formula. As for how to use it, you may have to find some craftsmen in Shaofu. Xue Qing said.

Huo Quzhi put down the wine cup and said, "I'll do it, those people are all familiar." ”

Xue Qing shook her head slightly: "What about familiarity, do you think that this place and this weapon can be touched by just a few people." What if it is leaked. ”

Huo Quzhi also faintly felt that the matter was important. Xue Qing made the stakes clear with him: "An archer may not be able to penetrate Yang in 100 steps after three years of training, and it will take four years for a rider to be able to ride well." In addition, how much is a horse and how much is the annual forage, these things are better than concubines. Our weapon does not need to be trained, it only needs to be lit and thrown into the crowd, the power is so huge, if the news spreads, whether it is the Xiongnu or the Han Dynasty, the princes of all parties, various forces, which will not be robbed with red eyes. ”

Huo Quzhi nodded: "Be careful, you must not leak the news." ”

Xue Qing took the opportunity to educate him: "So, before getting married, I always told you that everything a concubine said and did, you must not tell anyone, no one will believe it, you know why now." You, it's better to be a little more restrained, don't babble all day long, think more about things, listen more and watch more in everything, and talk less. This anyone, even anyone, whether it is the emperor and queen or your father-in-law, can't say ......"

Huo Quzhi hesitated: "Neither the emperor nor his uncle can ......"

Nonsense, especially them.

After eating and washing, it was not early, and after the party, the whole valley was silent. The two of them were lying on the couch, Huo Quzhi hugged Xue Qing with one hand, pillowed the back of his head with the other, kissed Xue Qing on the forehead, and said softly: "I thought about it carefully, although this thing is powerful, it may not be of much use to the Huns, who have no cities, no houses, and even no foot soldiers." This thing is most effective against piles of foot soldiers. When fighting with the Huns, the speed was very fast, the horses on both sides sprinted, and the change was only instantaneous, even if there was time to ignite and throw it out, maybe between two breaths, our horse team would step on it by itself. Besides, the gap between the cavalry is very large, and the horses are high, so if you can't blow up people, you just hurt the horse's feet, and throwing this weapon at most once in a battle may not have much effect. Unless this thing is more than ten times more powerful, like a crossbow that can shoot two hundred steps, then it will be completely different, I can kill the Hun cavalry with foot soldiers, so that they can't get in, oops, no, no, people are dizzy by the explosion, don't you know how to run? The Huns have never been able to win and run, ghosts and ghosts, they still need cavalry, tsk, such a good thing, how can it be done if it is useless, no, no, you have to think again.
