"You did it yourself?"

Listening to Xiao Zhengtai's words, Wang Jian suddenly stopped chewing potato chips, "You mean...... Can you purify salt? ”

"Hmm!"

Xiao Zhengtai nodded naturally, not thinking anything unusual at all.

The purification of coarse salt is actually very simple, there is no technical content at all, as long as you know a little chemical knowledge, you can do it!

"Master is waiting for me here, I'll show it to you!"

Xiao Zhengtai ran out again with his calves upside down.

After only a moment, Xiao Zhengtai turned back again, still holding a small paper bag in his hand, "Master, this is for you!" ”

Wang Jian opened the paper bag, and the tiny grains of refined salt inside shone brightly.

If it weren't for the mention of fine salt before, he couldn't believe that the tiny particles in front of him were salt!

"This ...... This......? Such fine salt is purified by the little boy? ”

The facts are already in front of him, but Wang Jian still can't believe it.

The fine salt in the palace has to go through many procedures to achieve, and even so, it is less than one-tenth of what is in front of you!

"That's right, if you want to fry delicious potato chips, you have to use this salt!"

When he was outside the palace, Xiao Zhengtai missed snacks and potato chips very much.

But I didn't get the potatoes, so it was useless to think about it.

"Master, if this salt is taken out and sold, can it make money?"

"Haha! Xiao Gongzi's craftsmanship is the only one in Daqin, if you really want to talk about the price, one gold for one or two is almost the same! ”

Wang Jian gave a fairly high evaluation.

One gold refers to a piece of gold cake, and the weight is about one tael, which is equivalent to a thousand copper coins, which shows the scarcity of refined salt in this era!

Nowadays, the technology is very backward, it is difficult to survey the salt mines, coupled with the low productivity, resulting in the annual salt production is very low, and the supply exceeds the demand!

"The little boy can purify salt to such an extent, has Your Majesty ever known?"

"My father has already tasted the stir-fry I made, but he doesn't know about salt yet!"

They had only been back for two or three days, and they had so many things in their hands that they didn't have time to mention it at all.

Today is the time to talk and get here!

"The little boy can tell Your Majesty, and Your Majesty will be very happy!" Wang Jian reminded.

"Okay, this time Master will take these back and taste them first, and then give them to Master after I refine them more next time!"

Xiao Zhengtai smiled and nodded, eating crunchy potato chips, which was quite enjoyable.

"Well, I can't imagine that you have such a wonderful idea at such a young age! I've heard that the horseshoe to reduce the wear and tear of the horseshoe was also invented by you? ”

Wang Jian stared at Xiao Zhengtai, who was more than a meter tall, feeling incredible.

"That's right, on the way back, I felt that those eliminated horses were a pity, so I drew a drawing!"

Xiao Zhengtai has a cute little face on his back.

"Just draw it?"

"Hmm!"

"Do you know that this casual painting has solved a big problem for Daqin for a hundred years, and it has also saved Daqin a lot of expenses!"

"What is this? I still have something that will increase the combat effectiveness of the cavalry! ”

"What?"

Hearing that it could increase the combat effectiveness of the cavalry, Wang Jian suddenly became interested.

"Master, wait a minute, I'll draw it for you!"

Komasa found a blank piece of paper and drew the shape of the saddle and stirrups on it.

Now Meng Tian has invented the brush, and the writing is very smooth.

But for drawing, Ying Feiyu still thinks that the pencil rewarded by the system is the best, and it must be mass-produced if there is a chance in the future!

"Master, please look!"

After the drawing was completed, Xiao Zhengtai handed it to Wang Qian, "This is called a saddle and stirrups, which can fix the body, even if a novice rides on a horse, it will not fall, if it is on the battlefield, with these two things, the cavalry does not have to worry about falling, and can concentrate on fighting!" ”

After Wang Jian heard this, his eyes became brighter and brighter, "Okay, if this thing is created, it will definitely make the combat effectiveness of the cavalry go to a higher level!" ”

"That's right!"

Xiao Zhengtai nodded, "If you have time to go back, let my father create these two things, and our Great Qin will no longer be afraid of the Huns' cavalry!" ”

"Well, I'm old, and I'll have to rely on you juniors in the future!"

Wang Jian shook his head and smiled bitterly.

The two talked a lot about the Huns, and Wang Jian was impressed by this five-year-old boy!

As described by his son Wang Ben before, this child should be a naughty and talented person.

But what he sees today is a quick-witted, calm and far-sighted child, who will become a great weapon in the future!

It is not wrong to marry Wan'er to him in the future!

When Wang Jian returned to the mansion, he just caught up with Wang Wan talking in the main hall, talking about Xiao Zhengtai's punishment of rape and evil in Xianyang City today!

When Xiao Zhengtai kicked Yan Le, his eyes were full of little stars.

"What? Does my family Wan'er have someone to admire? Ha ha! ”

Wang Jian walked slowly into the door with his hands behind his back.

"Grandpa, don't you know, the strength of that little short leg is really great, and he can lift Yan Le up with one hand, and hit him all over the ground looking for teeth!"

Wang Wan thought that her grandfather didn't believe it, so she said it again with her eyebrows fluttering.

"What is it to lift Yan Le? The little boy can lift the stone lion in the palace with one hand! ”

Wang Jian sat on the main seat and slowly poured himself a cup of tea.

"What? Dad, are you telling the truth? ”

Wang Ben's jaw dropped suddenly.

He didn't feel anything when his daughter Wang Wan talked about it before, that kid has a lot of strength, and he has seen it, but he didn't expect it to be so big.

Can you lift the stone lion in the palace?

The stone lions in the palace are taller than him, not to mention the weight, even if there are ten more, he may not be able to lift them.

That kid can even lift up one hand?

It's incredible!

"Grandpa, how do you know?"

Wang Wanmei's eyes widened, and she was obviously frightened.

If what Grandpa said is true, then wouldn't he become a clown?

I was clamoring all day long that I was going to beat people up, but it turned out that people didn't take it seriously at all, and they could throw themselves out with one hand!

And that amazing speed, she had never seen anyone faster than that little short leg!

If this goes to the battlefield, with the acceleration of the power in his hand, it will be easy to take the head of the enemy general!

"Naturally, I saw it with my own eyes......!"

Wang Jian took a slow sip of tea and told the two of them about today's events.

"I didn't expect that in addition to his strength, the little boy also has the talent to practice martial arts!"

Wang Ben felt ashamed.

In the entire Daqin, there are not many people who can make Lao Tzu praise, let alone praise for a long time!

I think that when he was learning martial arts, his human brain made his father scolded him as a dog's brain, and he finally practiced it!

"Grandpa, that kid wants to learn wargame deduction, is it possible that he wants to go into battle to kill the enemy in the future?"

"It's sooner or later, Daqin is a military merit system, and he is proud of his military merits, even if he is a prince, if he doesn't have any military merits, he won't be able to get a decent fief in the future, let alone inherit the throne!"

Wang Jian nodded.

Not to mention other princes, even Fusu, who has been studying Confucianism, has also gone to Shangjun for a few years to train, in order to inherit the throne in the future.

If you don't have any military merits, it means that you don't have a chance to be on the throne.

Even if the emperor agrees, it is impossible for the ministers to agree!
