"Uncle Da, this is for you!" Meng Yan suddenly remembered that someone from Jigu Zhai had come just now, and he sent the finished reading glasses over.

"For me, what?" Uncle Da took the small wooden box with some surprise.

"Uncle Da, you will know when you open it!" Meng Yan smiled mysteriously, and even Guo Nu on the side came over with some interest!

Uncle Da opened the box, and a pair of crystal reading glasses were lying in the middle of the box, which was specially customized by Meng Yan for Uncle Da, and I am afraid it can be regarded as the first pair of reading glasses in the Ming Dynasty.

"Uncle Da, try it on?"

"Dai, how do you wear this thing?" Uncle Da was stunned for a moment and asked puzzled.

Meng Yan reached out and took the reading glasses from the box, opened the frame, and then put them in front of his eyes, on top of his two ears!

"This, this ......" Uncle Da retreated again and again in shock, speechless with excitement.

"Lao Da, what's wrong with you, what is this?" Guo Nu asked curiously.

"Master, I can see clearly, I can see ...... clearly" After putting it on, the blurred object in front of him instantly became clear, which made Uncle Da excited and incoherent.

"What, old Da, are your eyes healed?"

"Master, yes, wear this ...... that the Mengshes gave me"

"Reading glasses!"

"Yes, reading glasses, I can see clearly!"

"It's really amazing, let me see?" Guo Nu asked in a strange way.

"Master, here you go!" Uncle Da took off his reading glasses, held them in both hands and handed them to Guo Nu.

Guo Nu wore it for himself as Uncle Da wore it!

"This, this, so clear......" Guo Nu was also speechless, but after wearing it for a while, he felt a little dizzy.

"No, you can't wear this thing, the official is dizzy!"

Meng Yan pursed his lips and snickered, Guo Nu is still young, the presbyopia is not very strict, and the degree is not high, while Uncle Da is deeply presbyopia, Uncle Da's reading glasses have a high degree, and he will naturally get dizzy when he wears them!

"Mengshe people, what's going on, why don't I get dizzy when I wear my head, but my lord gets dizzy?"

"This pair of reading glasses is specially made for Uncle Da, it fits your eyes, but it doesn't fit Uncle Guo's eyes, so you don't get dizzy when you wear it, but Uncle Guo gets dizzy!" Meng Yan explained with a smile.

"Then what should I do, my lord's eyes are not very good, can you make a pair too?" Uncle Da asked.

Guo Nu, who was dizzy and had not yet recovered, was also energetic when he heard it, pricked up his ears, and listened carefully.

"That's fine, but you need the right clear crystal!" Meng Yan nodded.

"This thing is made of crystal?"

"Yes, Uncle Guo, but the requirements for crystal are high, it must be colorless and transparent, and it will be processed according to the actual situation of everyone's eyes!" Meng Yan explained.

"Did you make this thing?" Guo Nu asked.

"I designed the thing, and I provided the number jù, but the person who did it did think that Master Ge was the master of Gu Zhai, and I didn't have that ability yet!" Meng Yan smiled.

"So they could do it without you?"

"Can be can, but without the number I give, they can only make the same kind of lenses, after all, everyone's eyes are the same, if the match is not good, it will deepen the disease!" Meng Yan Road.

In later generations, reading glasses did not have a fitting at all, and they were directly held and worn, and which one was suitable was chosen, which one was simple and fast.

But the Ming Dynasty has not yet reached that industrial level, and this kind of consumption is not something that ordinary people can afford, so they can only take the route of private customization!

"Meng Yan, how much does this cost?" Guo Nu's eyes suddenly narrowed slightly, and he suddenly changed from a member of the Sanpin Imperial Court to a profiteer.

"About ten taels of silver!"

"Ten taels of silver, it's not expensive!" Guo Nu nodded, this is not a consumable, if you buy a pair, it can be used for at least a long time.

"Uncle Guo, you don't want to do this business, do you?"

"Why, can't it? Many ministers in the DPRK and China have this problem, if your reading glasses can really help them see clearly, they are willing to pay any amount of money! Guo Nu smiled, with a standard profiteer face.

"Business can be done, but the source of raw materials is not easy, and this requires skilled craftsmen!"

"Well, behind Jigu Zhai is the British Gong Zhangfu, if we cooperate with them, we will have to give up at least half of the profits, but this is a businessless business, we actually still make money!" Guo Nu closed his eyes and said to himself.

"Uncle Guo, I have no objection to making money, but you should always keep a copy for me, right?" Meng Yan couldn't cry or laugh, this Guo Nu seemed to have completely excluded him, but he still made this reading glasses.

"You kid, have you lost your money?"

"I'm penniless now, and I still owe you two hundred taels of silver!" Meng Yan hit the sky and shouted.

"Well, you can't do the business without you, so how about letting you take 30% alone?" Guo Nu directly distributed the benefits.

"Uncle Guo, I'm also the inventor of this reading glasses, isn't this thirty percent benefit too little?"

"You kid, you are not greedy enough, if you don't go to Jigu Zhai, we can monopolize this business, but if you go, this business will give them a piece of the pie, do you understand?" Guo Nu sneered.

Meng Yan was silent, he understood this truth, even if he didn't give them business, if this thing came out, it was not very difficult to imitate it, if the master with good skills even made it was not necessarily worse than the original!

"We don't count the problem of craftsmen, the problem of raw materials is not easy to solve, we can't buy this kind of colorless and transparent crystal, right?"

Meng Yan nodded, but he didn't say that there was a substitute for this, but it wasn't made.

"In this way, it is almost impossible to bypass Jigu Zhai!" Guo said angrily, "Do you know that behind this episode of Gu Zhai is the British Gong Zhang Fu? ”

"But the British Duke Zhang Wenbi who commanded the army to quell the rebellion of the Han King during the Xuande period?" Meng Yan was surprised.

"Yes, it seems that the virtuous nephew has done a good job of homework these days!" Guo Nu nodded and said in appreciation.

"The little nephew heard that the King of Han rebelled back then, and sent someone to contact Duke Wen Bi, please respond internally, but Duke Wen Bi did not rebel, but instead exposed the King of Han plotting rebellion, but is there such a thing?"

"This is indeed the case, if it wasn't for Wen Bigong coming forward and exposing the conspiracy of the King of Han, I'm afraid the Ming Dynasty would be a different scene!" Guo Nu nodded and said.

"I'm afraid that it may not be, the king of Han is brutal by nature, stubborn and self-serving, not a benevolent monarch, even if he wins the world, he can't sit in the world!" Meng Yan Road.

"Boy, you are not small, you dare to say such things!" Guo laughed and scolded angrily, the matter has long passed, but there are still some taboos among the people.

"The little nephew is just talking about it behind closed doors, but he doesn't dare to talk nonsense to the outside world!" Meng Yan said with a smile.

"By the way, I heard Uncle Da say that you have some people under you, what's going on?" Guo Nu asked.

"That's a long story......"

"You can actually take these Jianghu killers for your own use, I really underestimate you!" After Guo Nu listened, he sighed.

"The little nephew is also a fluke, it's best not to kill evil, I don't want to kill people, especially my own compatriots!" Meng Yan Road.

"It's good that you can have this understanding, these people are also taking this path because they can't survive!" Guo Nu sighed, "If the imperial court can give them a way to live, they will not embark on this road." ”

"Uncle Guo, the little nephew wants them to change their names and join Jinyiwei." Meng Yan hit the railway while it was hot.

"This Jinyiwei has always recruited children from good families, if such a Jianghu killer joins Jinyiwei and is grabbed by the tail, it will be troublesome!" Guo said angrily, "Are they all wanted?" ”

"A few people do, others don't." Meng Yan Road.

"It's easy to do without a wanted warrant, but it's not okay if you have a wanted warrant, you also know that Jinyiwei is the Son of Heaven's pro-army, and such a scandal is not allowed!" Guo Nu said solemnly.

"Little nephew understands!" Meng Yan nodded, he couldn't eat hot tofu in a hurry, and he was a little too careful.

"The day after tomorrow, you will come directly to Nanya, bring Lan Dou's official robe, waist card and embroidered spring knife!" Guo Nu commanded.

"Okay, Uncle Guo!"

"You should prepare well today, I still have something to do in the yamen, if there is anything, tell Xiaochao or Yue'er!" Guo Nu commanded.

"Yes!"

East Detective Factory.

"Meng Xian's son is back, what the Queen Mother means, let's quietly do it, leave no trace!"

"Lord Weng, where is this kid now, we don't know yet?" Cao Jixiang asked in surprise.

"The Holy Lord has rewarded him with a trial hundred, and I believe it won't be long before he will appear on his own!" Wang Zhenyin smiled predictably.

"Understood, Lord Weng!" Cao Jixiang nodded.

"Remember, you must not let Jinyiwei catch the handle, otherwise, if something happens, no one will be able to take care of it!" Cao Jixiang said sternly.

"Please rest assured, the East Factory is doing things, and I haven't been on a business trip yet!"

"Well, I'm leaving, be careful!" Wang Zhen nodded with satisfaction and got up.

"Congratulations to the master!" Cao Jixiang and the other eunuchs said respectfully.

"Father-in-law Cao, why did the Queen Mother ......"

"Shut up, don't ask what you shouldn't ask, and if you don't want to lose your head, put away your curiosity for me!"

"Yes, Grandpa Cao!" The little eunuch quickly lowered his head in fright, but a trace of resentment flashed in his eyes.

His name is Xining, a Jurchen.
