"You made it yourself?"

After hearing Xiao Zhengtai's words, Wang Jian's movement of chewing potato chips suddenly stopped, "You mean... can you purify the salt?"

"Um!"

Xiao Zheng nodded naturally, not feeling anything strange at all.

Purification of coarse salt is actually very simple, and it has no technical content at all. You can do it with a little knowledge of chemistry!

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

Xiao Zhengta ran out again with her calf.

In just a moment, Xiao Zhengta turned back again, holding a small paper bag in his hand, "Master, I'll give it to you!"

Wang Jian opened the paper bag, and the fine grains of salt inside were shining.

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

"This...this...this...this is such fine salt purified by the young master?"

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

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

"Yes, if you want to fry delicious potato chips, you must have this salt!"

When she was outside the palace, Xiao Zhengta missed snacks and potato chips very much.

But it's useless to not get potatoes.

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

"Haha! The young master's craftsmanship is unique in the Qin Dynasty. If it really costs a gold price, it's almost the same for one or two!"

Wang Jian gave a very high evaluation.

One gold refers to a piece of gold cake, which weighs about one or two taels, equivalent to one thousand copper coins. It can be seen that the scarcity of fine salt in this era!

Nowadays, technology is very backward, and it is difficult to detect salt mines. In addition, the low productivity has led to a very low annual salt output and shortage of supply!

"Have your Majesty ever known that the young master can purify salt to this level?"

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

They have just returned for two or three days and have a lot of things in their hands, so they have no time to mention this matter specifically.

Today is just a rush to talk, and I’m here!

"Young Master, you can tell Your Majesty that Your Majesty will be very happy!" Wang Jian reminded.

"Okay, this time, Master will take these back and taste them first. I will give them to Master next time!"

Xiao Zhengta nodded with a smile and ate the crispy potato chips, which was quite satisfying.

"Well, I really didn't expect that you had such a wonderful idea at a young age! I heard that you invented the horseshoe that reduces wear and tear from horseshoes?"

Wang Jian stared at Xiao Zhengtai's figure who was over one meter away, feeling incredible.

"Yes, it was a pity for those eliminated horses on the way back, so I drew a drawing!"

Xiao Zhengta leaned down with a cute little face.

"Just draw it casually?"

"Um!"

"Do you know that this casual stroke solved a big problem that the Qin Dynasty has been in the past century and saved a lot of money for the Qin Dynasty!"

"What's this? I have something to increase the combat effectiveness of the cavalry!"

"What?"

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

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

Xiao Zhengta found a piece of white paper and drew the shapes of saddles and stirrups on it.

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

But for drawing, Ying Feiyu still thinks that the system reward pencil is the best, and if you have the chance in the future, you must produce in large quantities!

"Master, please see!"

After drawing, Xiao Zhengtai handed it to Wang Jian, "This is called saddle and stirrup. It can fix the body panels. Even if a novice rides on a horse, it won't fall off. If you go to the battlefield, with these two things, the cavalry don't have to worry about falling off and can concentrate on fighting!"

After hearing this, Wang Jian's eyes became brighter and brighter, "Okay, if this thing is built, it will definitely bring the combat effectiveness of the cavalry to a higher level!"

"That's right!"

Xiao Zhengtai nodded, "If you have time, let your father build these two things. Our Qin Dynasty will no longer be afraid of the Huns' cavalry!"

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

Wang Jian shook his head and smiled bitterly.

The two of them talked a lot about the Huns, and Wang Jian looked at this young man who was only five years old with admiration!

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

But what he saw today was a quick-minded, calm and visionary child who would become a great man in the future!

It is absolutely right to betroth Wan'er to him in the future!

When Wang Jian returned to the mansion, he happened to catch Wang Wan talking loudly in the main hall, all about Xiao Zhengtai punishing evil in Xianyang City today!

When Xiao Zhengtai kicked Yan Le with one kick, his eyes were filled with little stars.

"What? My Wan'er also admires people? Haha!"

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

"Grandpa, you don't know that the short legs are so strong that you can lift Yan Le up with one hand, making him look for teeth all over the ground!"

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

"What's the point of raising Yan Le? The young master can raise the stone lion in the palace with one hand!"

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

"What? Dad, what you said is true?"

Wang Ben suddenly fell off his chin.

When his daughter Wang Wan talked about it before, he didn't think anything was wrong. He had seen that kid with great strength, but he didn't expect that he was so big.

Can you lift the stone lion in the palace?

The stone lion in the palace was taller than him, not to mention the weight. Even if there were ten more, he might not be able to lift it up.

That kid can actually raise one hand?

It's simply incredible!

"Grandpa, how do you know?"

Wang Wan's beautiful eyes widened, and she was obviously scared.

If all my grandfather said was true, wouldn’t he become a clown?

He yelled all day long that he wanted to beat him up, but it turned out that he didn't take it seriously at all and could throw himself out with one hand!

And that amazing speed, she had never seen anyone who could be faster than those short legs!

If you go to the battlefield, it will be easy to take the head of the enemy general with the acceleration of his power!

"Of course I saw it with my own eyes..."

Wang Jian slowly drank a sip of tea and told the story of today to the two.

"I didn't expect that in addition to being powerful, the young master also has the talent for martial arts practice!"

Wang Ben felt ashamed.

There are not many people who can make him praise the entire Qin Dynasty, let alone praise it for a while!

I remember when he was learning martial arts, his father scolded him for being a dog-like brain, and it was finally practiced!

"Grandpa, that kid wants to learn military chess deduction. Could it be that he wants to go into battle and kill the enemy in the future?"

"It's sooner or later. The Qin Dynasty has a military merit system and is proud of its military merits. Even if a prince does not have any military merits, he will not be able to obtain a decent fief in the future, let alone inherit the throne!"

Wang Jian nodded.

Not to mention other princes, even Fusu, who had been studying Confucianism, went to Shangjun for a few years to inherit the throne in the future.

If you have no military achievements, it means you have no fate with the throne.
