When Laihu'er heard this, he immediately opened the secret letter and flipped through it.

What was written on it undoubtedly surprised him.

"Your Majesty, you studied the diesel generator last night, so you don't have the energy to see you off today?"

"And say that we will definitely be able to come back triumphantly, so we won't engage in all this red tape?"

Yang Guanglai didn't come to see him off, the difference was not big, but it saved trouble.

It's just that what makes them wonder is, what is this diesel generator?

Sima Dejiao immediately asked Yang Gonggong in surprise.

Gonggong Yang smiled bitterly: "Don't say that the generals don't understand, the old slave is by His Majesty's side all day long, and they all know nothing about this matter, and there is still no conclusion." ”

"If you ask too much, Your Majesty will be impatient...... I just said that in the future, I will let the old slave see what a real diesel generator is. ”

"Okay." After listening, everyone was shaken.

But then the expression returned to naturalness.

In fact, it is not the first time that His Majesty has done such an amazing move, and from past experience, no matter what this diesel generator is, it is worth looking forward to.

"Alright, guys, it's time for us to go." Laihu'er looked up at the sky, and before he knew it, the sky was about to dawn, so in order not to delay the march, he immediately ordered to go on the expedition.

Sima Dejiao, Su Dingfang, Li Jing and others nodded one after another.

After saying goodbye to Yang Gong, he set off with his army.

Hundreds of thousands of troops are advancing, and the land is densely packed with people, and it is terrifying!

In the Jiangdu Palace, by the time Yang Guang woke up, it was already noon.

After getting up and freshening up a little, when Yang Gonggong came in from outside, Yang Guangfang asked casually: "They have already set off?" ”

"Well, it's been almost three hours." Yang Gonggong replied.

"Three hours, have I been asleep for so long? No, you have to go to the craftsman's house to study the diesel generator, time is pressing, where did you get so much time to consume......" Yang Guang muttered.

When Yang Gonggong heard this, his face was full of black lines.

Your Majesty is really a little crazy about this diesel generator......

It seems that there is nothing else to care about other than this.

In the following time, Yang Guang forgot to sleep and eat to study the diesel generator, and the entire craftsman's room seemed to have become his laboratory. Even the entire Jiangdu Palace jumped with chickens and dogs, mainly because Yang Guang was looking around for alternative materials, and for one material, he could even gather all the eunuchs and palace maids together several times......

If they knew what Yang Guang was doing, it would be fine, but what Yang Guang had done had not yet been understood. As a result, everyone was quite depressed.

It is no exaggeration to say that if Yang Guang was not the emperor of the Great Sui, he would have been directly drowned out by all kinds of abuse......

This toss lasted for almost a month and a half.

On this day, in the early morning, there was a sudden loud noise in the craftsman's room. The astonishing explosion sounded, as if it had been earthquaked, causing the nearby Jinyi guards who were patrolling to hurriedly approach the craftsman's house, for fear of encountering an enemy attack.

Then, I saw that outside the craftsman's room, many craftsmen were standing there and looking inside curiously.

The brocade guards glanced at each other, and couldn't help but come up curiously.

Immediately after, in everyone's sight, a very strange-looking behemoth appeared.

That behemoth, not to mention the brocade guards, even those craftsmen can't recognize it!

As for Yang Guang, who was standing next to this behemoth, he didn't know how he operated it, but he saw that the behemoth immediately made a loud rumbling sound, and at the same time, an even stranger gadget placed not far away was like a lantern, "rubbing" and lit up.

The light was dazzling, like the sun's rays.

"That'...... What is it? Could it be the electric light that His Majesty is talking about? "Some craftsmen, looking at this scene, their eyes are almost straight.

They never imagined that it was amazing that something could emit such a dazzling light without candles!

Of course, the most eye-catching thing is the diesel generator.

Because it was filled with diesel, there was a pungent smell, especially the machine that kept trembling with the sound, which made many people's eyes can't help but show a little jealousy, after all, they had never seen such a strange existence before.

"After more than a month of hard work, fortunately, God has lived up to my efforts, and I have really been able to fix the diesel generator!" At this time, Yang Guang raised his hand and wiped the sweat from his forehead.

Suddenly his forehead was stained with diesel.

It's just that Yang Guang doesn't care about this at all, he has a bright smile on his face.

It was the first time since he crossed over that he had such a sense of accomplishment, even if he had defeated the Yuwen clan in the past and defeated Li Shimin in the Jiangdu, including the later imperial expedition and the defeat of the Tang army and the Luoyang army, he had never been so excited.

Because in his eyes, these people can't be compared with the high-tech products in their hands at all!

With the birth of diesel generators, it also means that Dasui finally has electricity, and there are too many fields that electricity can play, and in the next period of time, it will make the development of Dasui as fast as a rocket!

"Quick, all the craftsmen will come in for me, and I will build more diesel generators with me, and by tomorrow at the latest, I will see electric lights towering in every corner of the Jiangdu Palace!" Yang Guang's hearty laughter resounded throughout the craftsman's room.

Immediately after, the artisan room was once again in a state of hustle.

After having the first diesel generator, the second diesel generator, the third, and even the fourth are made according to the cat, and it is much simpler, and in just two days, more than 30 diesel generators have appeared in the craftsman's room.

Moreover, if it weren't for the limited materials, Yang Guang would even want to build more diesel generators.

At this time, everything is ready, only the east wind is owed, compared to diesel generators, electric lamps are easier to make, Yang Guang led the craftsmen, in the palace in turn to arrange street lights, as for Qin Ruyan, Empress Xiao and other people's rooms, Yang Guang is more intimate to install chandeliers.

Everywhere in the palace, many people are curiously looking at the street lamps, and they are honestly looking forward to whether this thing can be lit up.

Outside the palace, the civil and military officials got the news and also entered the palace together and ran to join in the fun.

For a while, wherever there are street lights, you can see a large number of figures gathered around, waiting for the night to fall.

After all, Yang Guang said that only after dark can the street lights have an effect......
