Xia Hongsheng's front foot returned to the "Datang Artillery-related Technology Secret Development Base" - this name was given by Xia Hongsheng himself silently in his heart - and the back foot, those soldiers who were originally selected from the Datang Navy Division, operated the catapult on the sea ship, and threw gasoline drums and bombs at the enemy target as accurately as possible, came here. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

They didn't know why they were singled out, and they never knew there was such a place. After arriving here, they gathered and stood in the courtyard, and then saw Xia Hongsheng walk out of the house and walk in front of them.

Even though they were surprised, excited, and puzzled, they were all well-trained soldiers in the end, although there were all kinds of emotions in their eyes when they looked at Xia Hongsheng, their posture still maintained a straight military posture, motionless.

"Gentlemen, are you surprised to see this general?" Xia Hongsheng smiled and said: "Let's tell you that I and the general were attacked by the Japanese people, so we killed two Japanese people, changed their clothes, and threw their bodies into the ditch and soaked in the water. It's hard in the middle, so it doesn't need to be said. In short, you all know that the general and the general escaped death and escaped. The reason why he did not appear to the public is for the sake of later considerations. ”

Hearing Xia Hongsheng's words, everyone was very excited, although they still remained gentlemen, and they didn't say anything, but the excitement in their eyebrows could be seen.

"I have summoned you here today for a secret mission that I would like to entrust to you." Xia Hongsheng glanced around and continued: "You must remember that here, as well as anything you see, hear, or experience here, is the highest secret of the Tang Dynasty. This secret must not be divulged to anyone, anytime, anywhere, or under any circumstances. Even if you are humiliated, even if you die, you can't leak half a word. Otherwise, it will harm Datang, and even more so the honor and reputation of Datang soldiers. Do you hear me? ”

"Humble duty hear clearly!" The soldiers shouted.

"Good!" Xia Hongsheng nodded and said, "In this way, you still need to listen to these words next." This is a place where a new weapon is secretly developed. This weapon is temporarily called artillery. It is a firearm. Its purpose, like the trebuchet used by you, is to deliver those bomb projectiles to specific enemy targets and destroy enemy targets. ”

When those soldiers heard this, their eyes immediately froze, and they listened more carefully.

Xia Hongsheng continued: "The difference is that the artillery is extremely powerful, and it can shoot projectiles that are far heavier than the bombs used by the catapult to a very long distance. You, tell me how much the projectile thrown by the catapult weighs and how far can it be thrown? ”

Xia Hongsheng casually pointed to a soldier and asked.

"Back to the general's words, the weight of the projectiles used in the stone thrower ranges from 20 catties to 80 catties, and the size of the stone thrower is different, and the distance thrown is also different. The smallest can be cast by two people, and the projectile weighs half a catty to four or five catties, which is used to meet the enemy; The larger single tip, double tip, whirlwind, tiger squat, etc., require several people to pull the cable, which can send a projectile weighing twenty or thirty pounds, up to 80 steps away. The largest and heaviest throwing car has five and seven pins, and it must be pulled by 100 people, and it can send 100 catties of projectiles, which can reach 50 steps away. The ships used by the sailors are all of the second type, and they are all whirlwinds, which can throw projectiles in all directions. The man replied.

"Good!" He answered very clearly, so that Xia Hongsheng couldn't help but look at him differently.

"The artillery that the general said is the heaviest and farthest, and it can shoot hundreds of catties of projectiles ten miles away, scatter and explode, and there is no armor left in ten miles!" Xia Hongsheng smiled and said in a deep voice.

The soldiers couldn't control it, and suddenly their eyes widened, their mouths opened wide, and they gasped.

Although Xia Hongsheng knew that he was exaggerating, it was also good for them to know the importance of this weapon to Datang, and do his best.

Seeing the shocked looks of those soldiers, Xia Hongsheng raised his hand and motioned for them to continue listening, and then continued: "You have good eyesight compared to controlling the stone throwing machine before. That's why I picked you out and came here to learn something, which will help you control the stone throwing machine and even the accuracy of the artillery in the future. You must know that no matter how powerful a weapon is, if it hits the wrong place, it will be blind. So in the next few days, you will learn some methods here that will help you improve your accuracy. Then when the gun is prototyped, learn how to handle and use it. Got it? ”

"General Hui, understood!" When the soldiers heard that they were going to learn how to use such a powerful thing, they were immediately excited and immediately shouted loudly.

Xia Hongsheng nodded: "Not bad, very good!" In this case, the next thing to teach you is a very simple and easy-to-use ranging method. In this way, it is enough to estimate the distance between the enemy target and our own without relying on external forces, and only by using the eyes and hands of the superior ones. Knowing the distance from our side to the enemy's target is the basis for using a catapult or later using artillery. Gain knew the distance, so he could adjust the force and height so that the thrown object hit the target. ”

Time was pressing, Xia Hongsheng directly started teaching, and said to those soldiers: "This method of estimating distance, called the 'jumping eye method', is a rough measurement by estimating the width of the ground seen by the jumping eye. Ben will explain the steps first, and then I will follow along to see if I have a look, and then I will explain it in detail. ”

"The first step is to raise your right arm and raise it flat! After that, the big finger of the right hand of the deep man is raised upwards, and the big arm must be perpendicular to the body of the er. Xia Hongsheng said, and those soldiers stretched out their right arms and did as Xia Hongsheng said.

Xia Hongsheng said again: "The second step, close your left eye, turn your waist, and make your right big finger cover what you want to estimate the distance." It's all against the pole on the top of the hill behind Ben General! See, the right eye and big finger of the next waiting are on the same line as the thing you want to estimate the distance from. ”

The soldiers continued to do so.

Then, in the third step, close your right eye and open your left eye. Okay, now, does the thing you want to estimate the distance of, that is, the pole, appear to the left of your big finger? Is there a horizontal distance between the pole and your big finger? Now Ben will tell you that the pole is five meters long! Then, you can estimate for yourself, how long is the pole that you see in your left eye and the section between your big finger? The fourth step is to multiply this number by ten, which is the sum of ten. In the end, what you get is the position of you, the approximate distance to the pole! Xia Hongsheng preached.
