"Huh!"

The old driver rushed behind Liu Eighteen with an arrow, and said with a triumphant smile:

"Hehe, three thousand, iron cannons that can fire fixed ammunition, the barrels of which are refurnace and forged with alloys.

The production principle of this batch of iron cannons should be a bit similar to that of the Mauser in the early stage, so the chance of exploding is very small, and if there is no accident, a gun can fire 500 shots......"

"Grass! Three thousand Mausers?"

Now, it's Liu Eighteen's turn to be stunned.

Seeing the anger in Liu Shiba's eyes, the old driver hurriedly smiled and said:

"After working hard all night, and forgetting to sleep and eat, I worked overtime......

Liu Shibai gritted his teeth in anger and said with a cruel smile:

"Gotta get it...... You tell the labor and management the results directly, don't talk to me about anything and work hard all night! Of course, I don't deny you the credit!

Don't think I don't know anything, don't you just treat those captured Tokugawa soldiers as horses that don't eat grass, and let them work hard, right?"

In three months, 3,000 guns were made, an average of 30 a day!

However, when I think of the Tokugawa Army, the five or six thousand soldiers who were captured, but in terms of the base, it is not impossible, but the handiwork must be a bit mysterious......

"Hee-hee!"

The old driver smiled mysteriously and said:

"I was lucky enough to find a huge piece of pig iron in the backyard of the Takeda family's Sunhouse, so I planed it into a simple machine tool that would make a rough iron cannon. ”

"Are you stupid for me? What do machine tools use for kinetic energy?"

Liu Shiba's eyes narrowed.

"I came up with it by chance, there are no big rivers and big reservoirs in this place, so it is okay to use people to make up for it......

The old driver explained it this way.

"Nani?"

Liu Shiba, this is the first time I've heard of it!

The old driver gestured into the distance:

"Didn't you ask someone to dig a huge water storage trench four or five meters deep outside the walls of Noda Castle?"

"Hmm!"

Liu 18 kowtowed and explained:

"That's right! At present, cold weapons are still the mainstream, and the battlefield is still dominated by infantry.

With a huge trench, Noda Castle would not have been so difficult to defend. What does it have to do with the power generation and the trenches?"

"Quack, quack, quack, but it matters. ”

The old driver's dry smile was as ugly as jagged.

However, Liu Shiba's eyes still paid more attention to the demeanor and gestures of the old driver......

After dancing for a long time, the old driver said mysteriously:

"The ditch was a bit of a hassle because it was too far from the river, so we used the canal to irrigate the farmland.

After connecting with a slightly larger canal, I tried to divert water from a large river a few kilometers away, but it didn't work out. ”

When Liu Shibai heard this, he stood up and stared at the mountains in the distance, he remembered that on the way he came, what was the great river?

It's an exaggeration, it must be a mountain stream spring......

Isn't that right-

Liu Eighteen asked strangely:

"The river you described is in that direction, right? I remember the terrain, the surrounding Noda Castle is the highest, and it is impossible to bring water here. ”

The old driver grinned and said:

"Hee-hee, have you forgotten the waterwheel? Along the road are human-powered waterwheels contributed by farmers and some large households.

Four or five people go barefoot and stand up and step on that kind of waterwheel, then the little gap between the channels and the channels doesn't exist, right?"

Hearing this, Liu Shibai seemed to suddenly realize, thinking of the moat, and then the waterwheel......

But the old driver definitely didn't treat people as human beings when he did this!

"What do you mean, I guessed a little! Is it to transport all the waterwheels along the way to Noda Castle?

Then, a waterwheel was placed every ten meters around the trench, and finally the soldiers who surrendered from the Tokugawa army stood on it and trampled on the ......"

Liu Eighteen tentatively said his guess.

"That's right! Hundreds of waterwheels spun wildly, and the water began to speed up gradually, and accelerated, and accelerated, and one waterwheel gave orders to another, so that the moat came to life completely, and gave me a desperate spin......

So, in the swirling and rushing man-made river, the speed of the water artificially generates enough electricity to collect, and finally these points are used on the simple machine tool. ”
