Huo Guang originally discussed with the Sang family about 30% of the profits, but this time as long as 20% of the Sang family, because the Sang family cooperated with the imperial court, Huo Guang understood that a large part of the interests would definitely belong to the imperial court, which was also Sang Hongyang's sincerity to the emperor, so he relieved himself that he didn't want 30%, he wanted 20%, and he came up with a prescription, and the Sang family did everything else, and he could accept 20%.

And Huo Guang firmly believes that following the million to earn 100,000, and following the 10 million to earn million, even if the imperial court does not directly intervene in the affairs of the Sangjia salt industry, but as the most important part of the official mountain and sea policy that the emperor wants to do, the emperor will definitely secretly help to make the Sangjia salt industry continue to grow.

I see that my share is smaller, but maybe the total amount will increase.

As for when the royal family will completely take over the salt industry and become an official camp, anyway, there will be no such a big thing as three or five years, and it may not even be completely official in the end, the Sang family will always have to leave some of the benefits, and Sang Hongyang is not a philanthropist, so he can earn a few years if he lies down.

After a few days, Sang Jin came to Huo Mansion in a carriage, which was actually quite close, but the big families always went out with their feet touching the ground.

Qiu Xiang opened the door and saw the woman with extraordinary talent getting off the carriage, and she was dwarfed at once, Sang Jin herself was extremely good-looking, plus she was dressed exquisitely when she went out, and she had luxurious robes, not to mention Qiu Xiang, 99.99% of the women felt inferior when they saw it.

Sang Jin was also quite surprised to see Qiu Xiang, ordinary people don't have such a white, tender and good-looking maid.

"Son-in-law, please inside." Qiu Xiang invited Sang Jin in, and as soon as she entered the courtyard, she saw Huo Guang smelting iron.

These days, Huo Guang has been obsessed with iron smelting, a whole yard of strange-shaped things, Sang Jin can't see what these iron rods, iron round cakes like things are.

"Ah Guang, are these all refined by you?" Looking at the strange things all over the ground, Sang Jin asked in surprise.

But it seemed to her that these things were defective, because they were so strange that she had never seen them.

Huo Guang stopped what he was doing, wiped the sweat from his forehead, and said proudly: "Yes, what do you think." "After these days of training, the things he refined have become more and more refined, at first the iron skin was rough and rough, and now the connecting rod he refined has some serious appearance.

Sang Jin was not very embarrassed and couldn't understand what these things were, but reluctantly said, "It's still ...... Not bad. ”

"Here, you can help me take a look." Huo Guang showed it in a hurry, regardless of whether Sang Jin came over or not.

As Huo Guang began to refine, the huge amount of Qi flowed, Sang Jin was surprised, she had never seen anyone who could trigger such a huge amount of Qi energy, and looked at Huo Guang blankly, from beginning to end, all in place.

When Huo Guang's refining was over, he walked up to her, took the refined piston and asked, "How about Sang Jin, the surface of this thing that I have refined now is very smooth." ”

Sang Jin came back to her senses, she didn't care about the strange thing on Huo Guang's hand that showed off.

"Ah Guang, your Qi is too much."

When she said this, the widow Wang happened to come out of the door, hurriedly retreated, and said secretly: "Young people nowadays speak too bluntly in broad daylight. ”

Huo Guang looked at Sang Jin suspiciously, if you don't investigate, you don't have the right to speak, why do you say this.

"Ah Guang, can you attract such a large amount of Qi every time you refine it?"

"Oh, you said this Qi, is this degree a big deal? That's pretty much it. ”

"At least ten times more than the average scholar."

Huo Guang scratched his head: "Then I don't have a concept." ”

"Oh, by the way, what are you looking for me?"

After a short shock, Sang Jin remembered what was going on, and said, "The method you said before, Father has agreed to give you two percent." ”

"Okay." Huo Guang replied simply.

Now he is focused on the steam engine, since the royal family has intervened in the matter of pearl salt, it is impossible for him to occupy it again, and he now has something bigger to do.

Sang Jin didn't expect Huo Guang's reply to be so bland.

"Guang, you don't seem surprised."

"Your father is a powerful character, he always does the right thing, which is conducive to his own decisions, although he cheated me, but to be honest, I admire him, no wonder he can create such a big family business."

Sang Jin looked at Huo Guang curiously, in addition to agreeing with Huo Guang's plan, her father also euphemistically expressed that she and Sang Yu could get closer to each other.

"What are you looking at?" Huo Guang felt Sang Jin's gaze and asked curiously.

Sang Jin's face turned red, lowered his head and said, "Ah Guang, what are these things you refining for?" ”

Huo Guang had a connecting rod in his left hand and a piston in his right hand, and pulled Sang Jin to the edge of a kettle and said, "Come on, you have a good look." ”

As he spoke, he lit a flame under the kettle.

Yes, Ah Guang started boiling water.

Sang Jin looked puzzled, looking at Huo Guang boiling water, this kettle looks no different from ordinary ones, the only difference is that its spout is blocked.

"Ah Guang, what is this for?"

"Boil the water."

"What happens if it burns?"

"Yes."

"And then?"

"The lid will be lifted."

The two do not seem to be communicating on the same channel.

As the water boiled and the lid of the pot was pushed up, Huo Guang put the connecting rod and wheel on the edge of the lid, symbolically dialed the connecting rod with his hand, and then said: "I thought of this kind of connecting rod, as the lid of the pot is lifted up and falling, driving the connecting rod and then connecting the wheel can make the wheel rotate." ”

"Huh?" Sang Jin still didn't understand.

"If this can be turned and then mounted on the car, you can boil water to make the car move, and you won't need a horse in the future."

The world without horses will always be so desirable.

Sang Jin seemed to understand and asked, "But what's the use of this?" ”

Huo Guang and her couldn't explain clearly: "I'll show you when I make it, I guess I'll have to find your father and ask him to invest some money in me." ”

Huo Guang has tried to make a steam engine these days, the principle of the steam engine is very simple, he has seen it on Bilibili and small video websites, and he has also learned it in his own school, but when he really wants to make a steam engine that can be used, he still encountered a lot of difficulties.

He knows the principle, but he can't memorize the details, so he can only build a little bit, polish a little bit, and study.

For example, the way the connecting rod and piston move, the structure inside the steam engine, he can only try it while thinking about it, and the parts made are getting better and better with the naked eye, but in the past few days, refining these things that look very strange to people in this era has made Huo Zhongru catch him and scold the stupid boy when he goes out and comes home every day.

Sang Jin thought about it slightly, but she couldn't figure it out, so she didn't want to, but said, "Ah Guang, you can taste the fresh ganzhe (sugar cane) I brought you." As he spoke, he beckoned his subordinates to bring him in.

As soon as I heard that Sugarcane Huo Guang was in the spirit again, without pearl salt, this is not another kind of small white crystal sent to the door, and art is indeed a crystal.
