Uncle Li didn't speak, just observed these new things with a more rigorous gaze, and from time to time whispered a few words with Uncle Li Jing who was standing beside him, and occasionally the two of them would smile knowingly, which made me feel chills all over my body, well, it seems that my thoughts are more evil.

Uncle Li just went around and observed this magical cylinder, then he looked into the distance, "Is that the city wall you built temporarily?" Uncle Li, who had been observing around with a telescope on the side, suddenly raised his hand and pointed to a high wall a thousand steps away on the opposite side and asked.

I nodded, "Exactly, this wall was built according to the thickness and height of the walls of the outer city of Chang'an, and its solidity far exceeds the solidity of all the cities in Goguryeo at present. ”

"Oh? Yes, Li Lao Aiqing, you can also take a look, how can that city wall be destroyed if it adopts ordinary siege tactics? Uncle Li turned back to Uncle Li Jing, who was also observing the opposite city wall. Uncle Li Jing shook his head with some regret: "If the city is full of such walls, then the old minister's suggestion is to besiege and not attack the party." This kind of city wall, I'm afraid it's not much worse than the city wall of our Chang'an City, if you attack it, it can be destroyed by manpower, unless you use more stone throwers, but it's also difficult to open the gap. ”

"What Qing Zhi saw coincides with me?" Uncle Li nodded approvingly and hooked his finger at me: "Son-in-law, last time you showed us how to destroy the city wall with a medicine bag, but the city wall built that time was not half the height and thickness of the current one, and now you are really sure that you can destroy the city wall directly from here?" ”

I saluted Uncle Li respectfully: "Father-in-law, don't worry, my son-in-law will never say anything." In my eyes, this wall is like that dirty chicken and tile dog. ”

"Little Housheng, don't blow it too much, when the time comes, there will be no good fruit for you to eat." Uncle Li Ji smiled and said this from behind. It makes me very angry, because I simply look down on me, and the work of the staff of the Martial Arts Research Institute for more than a year. For this reason, I want to tell all people that those who have the intellectual mind will be able to use the scientific method to turn that solid wall into a pile of mud.

At this time, Zhong Hua finally ran over: "Lord Fang, it's ready, all the gunners and loaders are all in place, and the ammunition has been prepared, all of which are made of new gunpowder this time, ten rounds per gun." ”

"Well, okay, you go over first." I nodded to Zhong Hua to indicate that I understood, and then reported the current situation to Uncle Li: "Your Majesty, all the work is ready, and I would like to invite all of you to come up to the stage and sit down." ”

----------------------------------------------------, "Well, that's it, I'll wait and see the virtuous son-in-law try, remember, don't let the old man down." "Uncle Li is still a little worried, mainly because the old guy has never seen a real war scene with large-scale use of firearms, which is not to blame him, today, I just want them to understand that cold weapons will eventually be replaced by powerful firearms.

After Uncle Li and the others sat down, I stood in front of these brave gunners who took their lives as child's play, and there were thirty mortars in a row, with a total of thirty gunners, thirty deputy gunners, thirty loaders, and thirty rangefinders. This is standard. They are all fearless, and their momentum is very indomitable, which is very proud.

Looking at these fearless soldiers, they do make me very proud, at least, I don't have the courage and courage to make this kind of home-made mortar, courage is precious, life is more valuable, adhering to the principle of safety first, and in order to make myself look heroic, so, I have put on a full-body armor, even a helmet, so as to make myself more psychologically safe.

I patted the stamped armor on my body, well, the defense should not be as strong as the bulletproof vest of later generations. Stretched out his hand and picked up the command flag, and waved it violently.

The gunner and the assistant gunner, with the help of the loader, attached the barrel to the gun carriage, so that the barrel was firmly attached to the gun carriage and the preparation procedure was carried out. "Start ranging!" Under my command, the thirty rangefinders who had been trained by me stood by the gun position, raised their right arm horizontally, made a fist with their right hand and raised their thumb, closed their left eye, overlapped the left side of their thumb with their right eye on the target in the same straight line, and left their right arm and thumb still, and then closed their right eye, and then looked at the same side of their thumb with their left eye, and they would find that the edge line was a distance away from the right side of the target, and then estimate or measure the length of this section, multiplying this length by ten, It is the actual distance between the gun emplacement they are standing on and the target.

It's a very simple method, when I was in the reserve, I watched a patriotic educational movie, fighting Vietnam, there were rangefinders who did this at that time, and then I asked a reserve officer who retired from artillery, only to know that this is a simple and effective hand-eye ranging method, I once used this method to measure the length of the college's field, and the error will not exceed two meters. In the era of Datang, I had no way to make a laser rangefinder, so I could only use this method to teach them.

This method is both simple and easy to calculate, so what they lack now is only skillful application, in fact, this method will also be used by gunners and deputy gunners, and rangefinders are just reserve personnel, just to make the best use of their materials, so let them all go into battle together.

Each rangefinder wrote down the various measured distances on a piece of paper and then reported the numbers out loud. I also took a measurement using the same gesture, and after estimating, well, it seems that their calculation is not very different from mine, and it is quite correct, the distance from the gun emplacement to the high wall is about 1,125 paces.

"One thousand one hundred and twenty-five steps! Gunner adjusts the angle! "Once again, the gunners began to fine-tune the direction of the barrel, and the gunners on the side had already taken the medicine bag, cut the lead according to the distance scale above the upper lead, and put the primer on the bottom of the barrel according to the amount of the off-hand.

Uncle Li and the others sat on the high platform, looking at these busy scenes with great interest, and soon, the preparations were completely ready. I signaled to Zhong Hua, who nodded knowingly, and hurriedly sent someone to distribute the cotton specially used to stuff his ears to the military generals and leaders sitting on the high platform.

And the gunners have already put on the earplugs that have been prepared for a long time. They can only stay with the artillery and plug in earplugs, at least it will reduce the damage to their ears and hearing from the roar of the artillery, and I have also taught them to keep their mouths open when firing guns, which is said to also reduce ear pressure and prevent eardrums from rupturing.

---------------------------------------------------- "What do you want to do with this?" Old Cheng is bright and bright-eyed, he doesn't need these things! Uncle Cheng refused aggressively, and laughed at Uncle Li Ji, who was hesitating on the side and wanted to plug his ears, Uncle Li Ji snorted and decided not to block this thing: "You Cheng Lao Puppet is not blocked, and Li is not blocked, who is afraid of who will come?" ”

These old guys are not good birds, no one wants to lose face in front of others, they all refuse, Li Daozong saw that none of the generals around him were blocked, and the famous general of the clan also refused: "I'm afraid of it, I've seen a lot of winds and waves, I want to march and rush on a thunderstorm night back then, kill the enemy and make meritorious contributions, are you still afraid that this little thing can hurt the general's ears?" ”

The result is that no old guy is willing to do this thing, Zhong Hua's hard persuasion is useless, so I have to move the eyes of the rescue to me, I look at the front of the serious as a wait-and-see, turning a blind eye to the rescue eyes cast by Zhong Hua, and even a little schadenfreude, I wish I could deaf these old men to be better, let them all retire from illness, so that I can save my energy.

Uncle Li picked up two balls of cotton, hesitated for a long time, and decided to grit his teeth and hold up as a tough guy, at least not to drop the price in front of Uncle Cheng, with a wave of his hand, he threw the cotton back into the wooden plate, and pulled the hair on his forehead very chicly: "Virtuous son-in-law, can you start?!" The old man has been waiting anxiously. ”

"Okay, the last general will take the order." I gave Uncle Li a solemn military salute, turned around, and helped the phoenix-winged helmet on my head, which also had a soundproof effect, and I had made full preparations in advance. "Ready!" I raised the green flag and commanded loudly: "Light the fire, let it go!" "As my flag waved down vigorously, boom!! There was an earth-shattering sound, as if a thunderbolt had exploded on the door of the head. The ears instantly had the illusion of a temporary loss of hearing, and the smoke from the full combustion of the gunpowder immediately erupted from the barrel of the gun, like a thick white mist, and the earth trembled with the strong force.
