Cheng Sanlang looked at this guy and couldn't help giving a suggestion.

"How about that, you go back to Luoyang first, and send this treasure to your father to impress."

As soon as this remark came out, Li Ke's eyes lit up immediately, but he quickly realized it.

"Really?...No, no, forget it, my father has already ordered me to enter Sichuan as soon as possible. If I go back again, I may be punished."

"But father is already ready to do something to Xue Yantuo. Having such a good thing is really a great achievement."

Ren Yaxiang who was standing aside couldn't help but nodded in agreement, but he was still reluctant to let go of the binoculars in his hand.

Cheng Chubi rolled his eyes. "Why go back to Chang'an, since we are all in Chang'an, then please directly invite one of the shareholders of Hantang Commercial Bank, His Royal Highness the Crown Prince, to present it to His Majesty."

"But having said that, this thing is very valuable. We can only give it away at most once. If the court needs it in the future, it will cost money."

Although Li Ke can't be good at writing, he can't be good at martial arts, but anyway, his civil and military skills are half-baked, at least he knows the benefits of finding out the enemy's opportunities first.

"Such a sharp weapon is worth spending no matter how much money is spent."

"But Brother Chu Bi, how did you come up with such a good thing?"

"Of course it was done for our Hantang Commercial Bank." Cheng Chubi also picked up one and looked it up in his hand.

The multiples of these telescopes are all around eight to ten times, although it is only a few times.

In fact, it is equivalent to making the observer look at the scene or object eight kilometers or ten kilometers away as if standing at a distance of 100 meters.

No matter how high the magnification is, it is not impossible to get it, but the lens will require more effort, and more importantly, eight to ten magnifications can be done by hand.

If it is more than ten times, then a bracket must be used to maintain stability.

The reason why Cheng Sanlang wanted to build this binoculars was that he already had ideas and ideas when he was engaged in maritime trade.

However, the quality of Western Region colored glaze at that time was really not good, all of them were colored glass or even variegated glass that could not be classified by color.

Zhao's Western Region Liulifang has undergone several years of process improvement and countless experiments, and now it has finally mastered the technology of producing colorless and transparent glass.

That's true, but the yield of colorless transparent glass that can really be used to make lenses is still not high.

Originally, these were prepared before and sent to Jiaozhi, so that the captains of the Han and Tang merchants could feel a little bit first.

Afterwards, they will be sold to peers. Of course, the price is naturally very impressive. Don’t buy too many of them, only sell for a hundred guan.

Compared to encountering pirates, encountering storms, and observing abnormal conditions on the sea, it only takes a hundred pennies. Don’t you think this is a price that can’t be conscientiously broken?

After all, research and development is very expensive and costly materials. Although everyone will say that stones are worthless, fuel is valuable after all, right?

Besides, being able to have such inspiration and invent such a good baby idea is definitely worth a lot. No, I want to go to the beautiful Southwest, but this news has only been revealed to Li Ke before, and my father must not know about it.

Li Shimin pointed at Cheng Sanlang with an angry and funny face and shouted.

"Why, do you still want to pretend to be stupid with the old man?"

"Do you know that in the first year of Zhenguan, your father took up the post of governor of Luzhou?"

"The military governors of Lu, Rong, and Rong prefectures, and the governor of Luzhou (now Luzhou, Sichuan).

You have made great achievements in suppressing the Tieshan Liao people's rebellion. After receiving the good news, the old man also rewarded your father greatly. "

"???" Cheng Chubi stiffened immediately. That's my home, my hometown, but my own father also went there for a spin?

And actually stayed there for several years... What the hell! Isn't this tacit agreement?

Unexpectedly, I would follow the footsteps of my own father and return to my hometown more than 1,400 years ago.

Li Shimin drove Cheng Sanlang out of the Great Hall with a smile.

I have to say that I just suddenly remembered that Cheng Yaojin had stayed there.

He worked there for several years before he was transferred, and there are still a group of veterans coming down there. No wonder that kid Cheng Sanlang would choose that place.

If Cheng Sanlang went there, Cheng Yaojin would be very happy, thinking about it, he would definitely let his old subordinate take care of his son more.

This kid Cheng Chubi is actually pretending to be stupid, hehe, that's all, the old man is too lazy to care about this kid.

It seemed that the father and son had already made plans. In that case, it might be a good choice for this kid to go with Ke'er.

If you want to make troubles, you can go to Luzhou to make troubles, so as not to make troubles in the prosperous central Shu area.

#####

Cheng Yaojin looked at the letter from Jiucheng Palace and couldn't help feeling a little headache.

"This kid, isn't this too noisy?"

"Before I insisted on encouraging people to go to that Jiaozhou, the old man also sent people to buy land there, but it didn't take long before he was tossing about to go to Liangzhou."

Cui at the side smiled and added some water and essential oils to the incense burner, so that the pleasant scent of flowers continued to permeate the air.

"Husband, it's no wonder Sanlang, after all, His Majesty gave it away for nothing, since His Majesty gave it for nothing, how can Sanlang not take it?"

"That's the truth, that's all, let him alone, others are worried that he will not be able to do anything."

"Now, I'm a father, but it's because of this kid's future. I really don't know how many gray hairs I have worried..."

Cui looked at her husband's glossy black sideburns, and naturally she would not expose her husband.

Besides, my husband was chattering like this and that, but in fact, I am afraid that he was already happy in his heart.

"Since Sanlang asked my husband to give you an idea, my husband can think about it. The 50,000 sets of cotton coats and cotton gloves will have to be delivered to the imperial court at the beginning of next summer."

Cheng Yaojin stroked his thick needle-like beard and smacked his mouth.

"It's not a big deal. Isn't Zhao Zhengyang specialized in silk and silk clothing in the stock music of their Hantang Commercial Bank?"

"With the strength of their Zhao family in Chang'an~lightnovelpub.net~50,000 sets, I'm afraid it won't take much effort."

"The problem now is not the 50,000 sets, but the need to provide 200,000 sets of winter clothes to the court in the year after next year's harvest..."

Just as Cheng Yaojin was talking to Cui Shi, the servant's voice came from outside, but it was that Zhao Zhengyang and his son had already entered the house.

#####

Zhao Zhengyang and his son sat in the front hall quite anxiously, but they didn't bother to touch the tea in front of them.

The father and son pondered over why the two of them were called over by the notorious General Cheng.

The mental pressure is too great. Fortunately, I have dealt with Mr. Cheng many times.

If you want to come to General Cheng, you should look at your own son's face and not make things too difficult for your own father and son...
