(I'm sorry everyone, it's really busy, the content in chapter 1043 yesterday should actually be in chapter 1044, I posted it wrong.) Pen, fun, pavilion www. biquge。 info In today's chapter, it's chapter 1043. I'm sorry everyone, it's really messed up, I'm sorry. ）

Datang's earth-shattering thunder itself is still in a very early stage.

An iron bump filled with explosives that leads to a lead. When you use it, you need to ignite the lead and then throw it out. Although the length of the lead is designed, it is theoretically possible to achieve different specifications between seven seconds and fifteen seconds to achieve different delay effects. However, since the lead is exposed and directly exposed, it will be affected by many conditions, which will lead to changes in the delay effect.

For example, sometimes when a horse is running, the sweat on the soldier's body may make the lead damp, so that the lead burns slowly. In addition, in the case of rain and snow, it is possible to extinguish the fire breaker, and the water on the ground and the snow and snow are too thick, and sometimes the lead may be extinguished.

But you can't hide the leads.

It's not that it can't be done technically, it's that it can't. In itself, the current Heaven-Shaking Thunder can only be ignited by fire, and it can only be thrown by the soldiers who ignite it themselves before using it again. In such a situation, asking the soldiers to find the lead before igniting it will undoubtedly bring great inconvenience to the use of the Heaven-Shaking Thunder.

Come to think of it, the person on the other side rushed over, and the soldier took out a sky-shattering thunder and wanted to throw it over. took out a sky-shattering thunder, and when the lead was taken out, it was too late to put it on fire.

If the defenders are just that, they can barely use it. If it's time to attack, where is the time to use it?

In order to facilitate ignition and shorten the ignition time of the earth-shaking thunder, a thumb-thick tube was specially designed on the armor of the Datang soldiers, which was used to stuff the fire fold. Then under the left chest or outside the right shoulder, so that the right hand touches out the earth-shaking thunder, and directly retracts the arm, and the earth-shaking thunder naturally reaches the left chest, just on the fire fold. Or in the posture of throwing hard, just bend the right arm, and the earth-shaking thunder in the right hand is just close to the fire fold fixed outside the right shoulder, igniting the fuse and throwing it directly.

At first, I couldn't help but glance at it, but after being proficient, I basically felt that when the earth-shattering thunder was ready to throw, I could directly ignite the lead, and it would be much faster to go from feeling out to igniting to throwing in one go.

But in the end, it is still extremely inconvenient.

It's also easy to burn to the point of self.

The tension on the battlefield is unnoticed, and sometimes a small piece of skin is burned after the battle. Fortunately, the Tang soldiers were all wearing clothes and armor, and the burns were not serious.

The root cause of this is the ignition method.

So since the earth-shaking thunder came out, Xia Hongsheng wondered when he would be able to come up with a flintlock device.

It's too advanced, and I don't know what impact type or something like that is, but the grenade in the anti-Japanese drama, this flint principle is not difficult!

It is to use the friction generated by the wire to ignite the flint or primer, and then ignite the explosive in the iron lump in front of the primer to produce an explosion.

The masters in charge of firearms research and development in the military aircraft workshop learned about this thing from Xia Hongsheng's mouth, and then looked at Xia Hongsheng's rough sketch, and then combined with their actual experience, they tried to try and try, use their brains, and find ways to do it, and now it is finally done!

With this thing, the time to use the Earthquake Thunder can be shortened to at least one-third of the original time, and the time saved on the battlefield will bring greater results. At least, in the time that one round of Sky-Shaking Thunder was originally used, three rounds can now be used, which may bring about a change in the tide of battle.

"Hahahaha, don't get excited." Xia Hongsheng's heart was surging, but he still raised his hand and pressed it down, signaled the people around him to calm down, calmed down his mood, and said, "Everyone, this son still has an idea." ”

When everyone heard this, their eyes lit up.

Xia Hongsheng's thoughts meant that it might be another opportunity for them to make meritorious contributions, so they naturally calmed down and listened carefully.

"This flint has been used by all of you." Xia Hongsheng said: "Rub the flint with a fire sickle, and then smash it heavily after it is hot, and it bursts out of the spark, lights the moxa, and makes a fire." Am I right? Or maybe two pieces of flint can burst out with sparks when they are sharpened so hard, isn't it? ”

"That's right, grandpa, this is ......" everyone was puzzled.

Xia Hongsheng looked left and right and pointed to the corner of the wall. There was a wooden wheel over there, Xia Hongsheng pointed to the wooden wheel and said to Qi Yong: "Qi Yong, go over and bring it!" And the half brick next to it! ”

Qi Yong ran over, picked up the small wooden wheel, picked up the half of the brick, and ran over.

"Look at the gear." Xia Hongsheng took the wooden wheel in one hand and said, "This thing will turn, right!" ”

Everyone, you look at me, I look at you, and they all look at Xia Hongsheng.

"This ...... The gears naturally turn...... As long as it's round, it will turn! The old master was puzzled and said suspiciously.

"Yes, then can we make this wooden wheel into a steel wheel, this steel wheel?" Xia Hongsheng said.

"Got steel wheels, huh? Nowadays, most of the gears are made of steel. The old master was even more puzzled, and felt that Xia Hongsheng was wrong: "Grandpa, what's wrong with you......"

Xia Hongsheng clapped his hands: "That's right!" Make this steel wheel wider, make the surface rougher, make some protruding lines, and let it grind your hands! And—"

Xia Hongsheng took the half of the brick from Qi Yong's hand again, and continued to gesture and said: "This half of the brick is like a flint!" Give them so much to get together! ”

As he spoke, Xia Hongsheng turned his head on the half of the piece in his hand and pasted it on the wooden wheel.

"In this way, look, as soon as the steel wheel on this side turns, it grinds to the flint on this side." Xia Hongsheng turned the wooden gear in his hand and said, "If you turn it like this, the steel wheel and flint will be sharpened, can you grind out the sparks?" ”

The old master nodded: "It's such a reason!" ”

"Then make this steel wheel small, so that it is the size of a fingernail, and then make a small piece of flint, and make it the size of a nail. Pin them together. Xia Hongsheng made a lighter action: "In this way, with a strong rotation of the thumb, the small steel wheel grinds with a small piece of flint, and grinds out the spark." Get another wick next to it, just enough to catch the sparks. As for the wick, go down into an iron box, get a little gasoline in the iron box, flood some of the wick, and soak the wick. In this way, the spark grinding next to it touches the thread, and the thread is soaked in some gasoline, but it doesn't catch up at once? ”

"Huh? Wouldn't the fire go down the line into the tin box and burn the gasoline inside? A craftsman next to him asked.

"Isn't that the time to see what you're capable of?" Xia Hongsheng spread his hands and said, "Why didn't the flame burn the oil below along the wick when the lamp was lit?" If gasoline doesn't work, try kerosene...... By the way, try filling the tin box with a cotton wick soaked in kerosene, or it may work. Or any other way, you can figure it out for yourself! Okay, remember this thing, it's done, it's a great achievement! This son wants to enter the palace immediately, this grenade ...... The new type of earth-shaking thunder, I have to show it to Your Majesty. ”

"Huh? Childe, I'm afraid I can't bring this into the palace! Qi Yong was taken aback.

Xia Hongsheng waved his hand: "Don't worry, I have a way." Go, bring a few more. ”
