"Ding, congratulations to the host for the successful lottery and the consumption of 500,000 points."

"Ding, congratulations to the host for drawing ten super cannons and Shenwei generals."

"Ding, congratulations to the host, you have drawn a hundred special cannonballs for the Great General of Shenwei."

"Ding, congratulations to the host, I drew the cement making process skill book."

"Ding, congratulations to the host, I got a hundred walkie-talkies."

"Ding, congratulations to the host, you have drawn 100,000 miner's lamps!"

"Ding, congratulations to the host, twenty water trucks and fifty dining cars have been drawn."

"Ding, congratulations to the host, I've got a steam engine."

"Ding, congratulations to the host for getting a propeller."

"Ding, this lottery is over, I wish the host a happy and happy one!"

At the end of the lottery, the system also played a small piece of music rarely.

Zhu Youzhen couldn't help frowning, except for the Shenwei General and the steam engine, what kind of thing was the reward.

500,000 points, if exchanged for silver, is as much as 5 million taels of silver, which is not a small amount.

The system is obviously cheating, and there is a 50% discount reward, which is just a trap, and I just want his points.

"System, you thing, just reward these things? I'm 500,000 points, Nima is too dark, too greedy! ”

"Ding, the host must know that everything you have now is given by the system, can't the system collect some benefits? System upgrades also need points, if you don't get a 5% discount, these things need a million points! ”

"I'll ......"

Zhu Youzhen touched his head and felt that what the system said made sense, although the prize was super expensive, it could be understood because of the different eras.

Besides, if there is no system support, he would have hanged himself by now.

"Hehe, forget it, I don't care about you, I'm giving you 100,000 points to upgrade!"

Zhu Youzhen generously sent 100,000 points to the system, the stronger the system, the stronger he is, it is worth it!

But half a day passed, and the system didn't move at all.

"Damn, the system is still angry."

Zhu Youzhen hurriedly went into the system to check the points.

It turned out that the points had been deducted by 100,000 points.

", I received the benefits, and I didn't even say thank you......"

Zhu Youzhen doesn't care about the system, he first has to check the prizes drawn.

When the mind entered the system warehouse, the first thing that caught his eye was the general of Nashimen Kamui.

Zhu Youzhen was immediately taken aback by these ten cannons.

This Shenwei general is so big that the muzzle of the cannon can drill into a big living person.

Looking at the hundred special shells for General Kamui stacked next to them, they were also extraordinary.

The weight of each shell is more than 500 catties, which is almost as tall as an adult.

Looking at the instructions, the cannon can also be disassembled and shipped, and then reinstalled in the place.

Zhu Youzhen nodded, he was very satisfied with General Shenwei.

Looking back at the steam engine, it was actually really good.

I gave Zhao Shizhen the blueprints of the steam engine a while ago, but they haven't eaten it all yet.

Now that they have a sample, the problem with the steam engine should be solved.

A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work.

The advent of the steam engine caused the Industrial Revolution in the 18th century.

Until the beginning of the 20th century, it remained the most important prime mover in the world, and later gradually gave way to internal combustion engines and steam turbines, among others.

When the steam engine works, it needs a boiler that boils the water to produce high-pressure steam, through the combustion process, the water boils for steam, and the steam expands to push the piston to do work.

The world's first steam engine was invented by the ancient Greek mathematician Hero of Alexandria, which was the prototype of the steam engine.

In 1679, the French physicist Denis Barben, after observing steam escaping his pressure cooker, built the first working model of a steam engine.

His contemporary, Samuel Moran, also proposed the principle of the steam engine.

In 1698 Thomas Sevelli and in 1712 Thomas Newcomen built the early industrial steam engine.

They all made their own contribution to the development of the steam engine.

As for the propeller principle, it is very simple, and the blacksmiths of the Ming Dynasty have the ability to make it.

When he heard the system report on what water wheels and dining trucks were rewarded, Zhu Youzhen had no idea.

He didn't think this thing was useful, but when he saw the waterwheel dining car, Zhu Youzhen suddenly smiled.

The so-called waterwheel is a large iron pot with some faucets for water underneath.

But the chassis is beautiful, all of them are six wheels, made of pure iron, because the bearings are very good, and the waterwheel is very flexible.

He thought about it for a while, this thing should be given to Yue Fei at best.

The geography of Mengyuan is vast, and the water source is not very sufficient, so it can be used in an emergency when marching and fighting.

The structure of the food truck is similar to that of a water wheel, like a small house, and there is no need to dig a pit in the ground to bury a pot to cook food when marching and fighting.

Putting some coal in the car and lighting a fire directly to cook will leave no trace compared to the primitive way of cooking, and it is also suitable for war.

Looking at the rest of the walkie-talkies and miner's lamps, Zhu Youzhen was angry and funny.

The miner's lamp is still somewhat useful, it can be lit at night, and it is a big deal to throw it away when the battery runs out.

But does the walkie-talkie have any bird use, and it can't be used at all now.

But thinking about the magic of the system, he decided to give it a try.

So I took out two walkie-talkies and turned on the switch, and there was a buzzing sound.

Zhu Youzhen was overjoyed, immediately adjusted the walkie-talkie to a frequency, and said to Yue Nu:

"Ah Qing, you take this thing and go outside, wait until you hear me speak, you must answer, go quickly!"

"Obedience"

Ah Qing took the walkie-talkie, turned it up and down, left and right, and looked at it a few times, but he didn't understand anything.

"Your Majesty, what is this, can it kill people?"

Ah Qing's words, Zhu Youzhen almost burst out laughing, thinking about the era in which Ah Qing lived, he put away his sword and smiled.

"Poof...... No, no, it's for dialogue, you'll soon know what's going on, get out of here, at least five hundred steps away from me. ”

"Oh, A-Qing obeys!"

Ah Qing agreed, and disappeared in front of Zhu Youzhen in an instant.

Zhu You got up to see the distance between Ah Qing and him, but found that Ah Qing's shadow floated out of the Qianqing Palace by himself.

"This stupid girl, why did you run so far!"

Zhu Youzhen shook his head, he felt that Ah Qing was running too far, and it was very likely that the walkie-talkie could not be contacted.

Turning on the walkie-talkie, Zhu Youzhen began to speak:

"Ah Qing, where are you now, please answer ...... heard"

Ah Qing stood outside the Qianqing Palace, still rummaging and studying the things in his hand.

Suddenly, a voice came, and the frightened A-Qing's hand shook, and the walkie-talkie fell to the ground.

"Ah Qing Ah Qing ......"

"Oh...... Smack......"

The quality of the walkie-talkie is not bad, and it has not been broken because of this, and Zhu Youzhen's voice is still calling inside.

Ah Qing stared at the monster in front of him blankly, and didn't react for a long time.

It wasn't until she remembered the emperor's explanation just now that she picked up the walkie-talkie in disbelief.

"Can A-Qing hear me? Ah Qing ......"

"Your Majesty, the concubine can hear you."
