Glasses did not appear in modern times, there were already prototypes of glasses before the Song Dynasty, and they had been promoted in the Ming Dynasty, while glasses before the Ming Dynasty only had lenses, no frames, and frames only appeared in the late Ming Dynasty.

At that time, the lenses were polished from crystal.

Tang Zhou didn't know this, but when he saw the crystal, he understood at a glance that the crystal could be used to make lenses.

So after he got Princess Chengyang's crystal ball, he returned to the house and began to polish the lenses.

Under normal circumstances, as the age increases, the eyes will generally be farsighted and become presbyopia, but the eyes of the old lady are short-sighted, so Tang Zhou has to polish the crystal into a concave lens, so that it can correct the eyes of the old lady Cheng.

It takes a lot of time to polish the lenses, so Tang Zhou locked himself in the room and worked for several days before finally grinding the two lenses.

However, after Tang Zhou did this, he was not in a hurry to go to Cheng's Mansion to let Mrs. Cheng try it, he spent a lot of effort to make these glasses, if there was no benefit, how could he give them away easily?

Tang Zhou first revealed a little bit of the news to Cheng Chumo, saying that he had a way to make Mrs. Cheng's eyes better, and after Cheng Chumo heard the rumors, he immediately told Cheng Yanjin again, Cheng Yanjin is a very filial person, as soon as he heard this, he immediately led people to Tanghou Mansion.

After entering the Tang Hou Mansion, Cheng Yanjin shouted loudly: "Tang family boy, I heard that you can make my mother's eyes better?" ”

Cheng Yanjin shouted and walked to the living room, entered the living room, and saw Tang Zhou chatting with two women, he rubbed his eyes, and saw that the two women were Princess Danyang and Princess Chengyang, his heart was shocked, and then he hurriedly stepped forward to salute, his attitude was no longer as casual as just now.

Although Princess Danyang and Princess Chengyang are women, after all, from the royal family, he dare not slack off.

Tang Zhou was very satisfied with Cheng Biting Jin, in fact, he just calculated that Cheng Biting Jin was coming, so he invited Princess Danyang and Princess Chengyang, firstly, because Princess Danyang and Princess Chengyang both knew about this, they really wanted to see if his Tang Zhou's glasses were really so powerful, and then he wanted to sell his glasses to Cheng Bitingjin, if these two princesses were there, Cheng Biting Jin would not dare to be presumptuous, many things were easy to discuss.

After Cheng Biting Jin saluted Princess Danyang and Princess Chengyang, Princess Danyang said, "Why did Lu Guogong suddenly come to Tanghou Mansion?" ”

Cheng Yanjin's eyes rolled slightly, his gaze swept over Princess Danyang and Tang Zhou, and there were some doubts in his heart, he really didn't understand how Princess Danyang came here, but he didn't dare to ask.

"Back to the princess, my mother's eyes are not good, Tang Zhou said that there is a way to make my mother's eyes better, so let's see what he can do."

After Cheng Biting Jin finished speaking, Princess Danyang sighed, and then looked at Tang Zhou: "Tang Xiaohou really has a way?" ”

Danyang Gong starred really not very well, but at this time, Tang Zhou didn't have much to say, so he could only continue: "Back to Her Royal Highness the Princess, Ben Hou really has a way, but the price is very high, Ben Hou is only afraid that Lu Guogong will not spend this money." ”

After Tang Zhou finished speaking, Princess Danyang and Princess Chengyang immediately set their eyes on Cheng Yanjin, but at this time, Cheng Yanjin was dumbfounded, why did he still spend money? He thinks that with his relationship with Tang Zhou, this matter still costs money?

If Princess Danyang and Princess Chengyang weren't there, he would have immediately pumped Tang Zhou over at this time, but now that they were both there, he hesitated for a moment, and then said: "The boy of the Tang family said that, as long as he can make his mother's eyes better, it doesn't matter how much money he has." ”

At this time, Cheng Yanjin had no other choice at all, if he was sorry for the money, he would be charged with unfilial piety, and the crime of unfilial piety in this era had a great impact on his career.

Now that Princess Chengyang and Princess Danyang are both here, how can he fall into the hands of others?

Tang Zhou saw Cheng Biting Jin say this, and smiled: "Lu Guogong is really my rare filial son in the Tang Dynasty, and the little nephew has something, but the eyes of Mrs. Cheng are as good as ever, this price is a bit high, five thousand, I don't know if Lu Guogong wants to buy it?" ”

As soon as he heard five thousand guan, Cheng Jin's heart suddenly hurt and wanted to drip blood, and he couldn't help biting his lip, but the words just now had already been spoken, how could he regret it, and said: "Five thousand guan is not much, as long as I can make my mother's eyes better, I want it." ”

Hearing Cheng Yanjin's words, Tang Zhou smiled: "Okay, then it's decided, let's go to the house." ”

Looking at Tang Zhou's appearance, Cheng Biting Jin really wanted to slap it over, why is this kid not authentic now, even dare to pit my money, wait for the two princesses to leave, see how I clean you up.

Everyone said yes, and went directly to the Lu Guogong Mansion.

After entering the backyard and seeing Mrs. Cheng, Tang Zhou took out his glasses, Cheng Biting Jin saw Tang Zhou take out a strange-shaped thing, he couldn't help but condense, he thought that Tang Zhou would have some medicine, but he didn't think about it, but he took out something like a child.

"Tang boy, don't be kidding, this thing can make my mother's glasses better?" Cheng Biting Jin didn't believe it, and Princess Danyang and Princess Chengyang at this time also didn't believe it.

Tang Zhou smiled: "It doesn't work, I'll know after Mrs. Cheng puts it on." Saying that, Tang Zhou handed the glasses to Mrs. Cheng, who took them and put them on, at first she was a little uncomfortable, but after a while, she suddenly stood up from the chair, pointed at Cheng Yanjin and said, "Son, how did you become like this?" ”

As soon as Mrs. Cheng spoke, everyone was shocked, and secretly thought that after Mrs. Cheng put on her glasses, everyone who saw it was deformed? Tang Zhou frowned secretly, thinking that it was unlikely, if the glasses were not good, at most he would not be able to see people clearly, and the deformation would be impossible, right?

Cheng Yanjin was also confused by his mother's words, and he didn't know how to answer for a while, just when everyone was puzzled, Mrs. Cheng suddenly sighed: "Hey, in my mother's heart, you are still the high-spirited young man back then, I never thought that after many years, you also have gray hair, wrinkles, old, old, your mother is in her seventies, how can you not be old?" In the past, my mother's eyes were not good, and I didn't look at you carefully, but now I can see it clearly, and I feel that the years are ruthless......"

Mrs. Cheng's words came out, and everyone understood what was going on, it turned out that Mrs. Cheng's eyes were better, but she found that her son was older than before.

After everyone understood what was going on, they immediately became excited, they never thought that this thing made by Tang Zhou could really make Mrs. Cheng's eyes better, they felt that it was amazing, this glasses was simply a divine thing.

And just when everyone was excited, Mrs. Cheng swept Cheng Mo and Tang Zhou with a pair of eyes, then shook her head and sighed softly: "Ugly, really ugly, incomparable, incomparable......"
