That is to say, diesel or something, it is not a problem at all.

Just last night, Yang Guang had asked Yang Gonggong to collect crude oil.

If nothing else, it will soon come to fruition.

This also allows Yang Guang to specialize in diesel generators without much worry.

The principle of diesel generators, Yang Guang once saw from books.

To put it bluntly, diesel drives the generator to run and converts the energy of diesel into electricity.

Of course, this whole process is simple to say, in fact, the internal structure is extremely complex, and the expertise required to make the diesel generator really come in handy is amazing, especially when no one can assist and help, and it is undoubtedly a bit difficult to complete this matter by Yang Guang alone.

If nothing else, the basic structure of the diesel engine is alone.

Such as cylinders, pistons, cylinder heads, exhaust valves, bearings, flywheels and other components, let Yang Guang have two big heads.

Not to mention, there are more complex intake strokes, compression strokes, combustion and work strokes, and exhaust strokes.

Ordinary people, as long as they hear this, I am afraid that they will have the heart of retreat.

Yang Guang is no exception, when he was about to start working, he actually began to retreat in his heart, because he didn't know whether his move would be successful.

If you fail, then everything you do now is equivalent to doing useless work and wasting time in vain.

It's just that when he thought of the many benefits that electricity would bring to Dasui, Yang Guang's heart became much firmer.

Everything I do is for the Great Sui and for the goal of "One Emperor of the Ages"!

But it is undeniable that even if Yang Guang has a blueprint for making diesel generators and has drawn all the drawings, in this era of cold weapons, there is still a lack of all the necessary materials.

He searched the entire craftsman's room, but he couldn't find a single screw or copper wire......

"It seems that every part of the generator has to be made by myself......" Yang Guang sat on the ground, only feeling his head big for a while.

The craftsmen who were busy working nearby, seeing Yang Guang like this, knew that His Majesty must have encountered a problem, but they knew it, but few people dared to come up to hear the news, only the director of the craftsman's room who happened to return to the palace to do business saw it, so he dared to ask by reporting the recent situation of the toy factory.

"Your Majesty, you came to the craftsman's room to make something yourself?"

"yes." Yang Guangfang admitted.

The corners of the craftsman's room director's mouth twitched vaguely.

Other emperors may not be close to the craftsman's room for half a step in their lives, Yang Guang is good, he runs here three times and two times, and his hands-on ability is also very strong, and he has to make some new things at every turn.

While feeling very puzzled, the director of the craftsman's room also asked curiously: "There are new small toys again?" ”

"No, what I'm going to make this time is a diesel generator. This is something that benefits the country and the people, and it is a hundred times higher than the specifications of toys. ”

"Diesel generators? The slave is lonely and unheard, and has never heard of it......" The director of the craftsman's room only felt that his eyes were dark, and he didn't know anything.

Of course, Yang Guang didn't expect this, just pinched the thin rope in his hand and said to himself: "This rope is a little bit worse after all, it doesn't conduct electricity at all, it would be nice if there was a thinner one......"

Yang Guang's original intention was to hope that pies could fall from the sky, so that he could get copper wires effortlessly.

But these words fell on the ears of the director of the craftsman's room, but it really turned into Yang Guang wanting to find a thinner rope, so his eyes lit up, and he flattered him and took out a thin gold wire from his arms: "Your Majesty, look at this gold wire, it should be thin enough, right?" ”

"Golden wire?" Yang Guang's heart moved, that's right, gold wire can indeed replace copper wire! It also has the effect of conducting electricity. Why didn't you remember it just now?

In the harem, golden silk is not uncommon.

In fact, some concubines will have some gold threads on their clothes to a greater or lesser extent.

He stroked the gold wire in his hand, raised his head and glanced at the director of the craftsman's room, playing with the taste: "The price of gold wire is high, you are a little craftsman room supervisor, where did you get the gold wire?" ”

"Your Majesty, there is no corruption among the minions!"

The director of the craftsman's room was taken aback, and couldn't help but kneel on the ground and shout loudly: "Didn't Your Majesty reward a lot of silver taels last time?" So the slave managed to buy some gold wire and prepared it to give to his wife at home. ”

"Oh, it seems that you and your wife are very affectionate?" Yang Guang couldn't help grinning.

The director of the craftsman's room smiled bitterly: "The slave stays in the palace all the year round, leaving her alone, and she is like a widow for ten years, and now that she has silver, she can't be neglected......"

"Well, a peerless good man, he can barely compare with me." Yang Guang praised it, and then sent it away casually.

As for himself, he collected gold threads everywhere in the harem.

The concubines in the harem were quite surprised when they saw Yang Guang suddenly come to the door to rebel at first, mistakenly thinking that they had finally reminded His Majesty that they had the opportunity to sleep. As a result, when I knew that Yang Guang's trip was only for the golden silk, and it was almost a robbery for nothing, what was originally quite a happy thing suddenly changed its flavor and became a disaster.

For a time, chickens and dogs jumped in the harem.

Almost every concubine was looted by Yang Guang, which made everyone cry bitterly, and the entire harem fell into endless grievances.

In this regard, Yang Guang felt guilty, but he couldn't take it at all.

Besides, he didn't feel sorry for his wives.

When the lights are ready, won't everyone be able to enjoy the convenience brought by high technology?

Two hours passed, and Yang Guang collected a room full of gold wires, which was enough for him to toss for a while.

It's just a pity that this is just one of the many problems, and there are more problems, still waiting for Yang Guang to overcome them one by one, but Yang Guang is full of energy now, and he doesn't feel troublesome at all, he has only one thought in his mind, that is, even if he is tired to death, he must try his best to get the diesel generator out!

Time passed, and in the blink of an eye, it was time for the army to set out.

Sima Dejiao, Lai Hu'er, Su Dingfang, Li Jing and others, commanding an army of 100,000, waited outside the city for Yang Guang to come out to see him off.

However, he waited left and right, but never waited for Yang Guang, only waited for Yang Gonggong and a letter sent by him.

"Your Majesty, is there something important that you can't get out of?" Lai Hu'er took the secret letter from Yang Gonggong and asked casually.

Gonggong Yang smiled dryly: "General Hu'er, you don't need to ask the old slave about these things, you just need to open the secret letter and take a look, and you will understand it all......"
