Glasses is a profiteering industry, Tang Zhou made more than 100,000 yuan in just a few days by making glasses for some people, which is faster than Cuiminglou making money. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

But this can't be done for a long time, after all, there are a few people who can afford the price, and there are not many people with glasses who are short-sighted or farsighted, after all, the words of this era are very big, and these readers don't have the pressure of his time, they have to read books every day or something.

So after Tang Zhou harvested a stubble, his business became cold.

However, after his business cooled down, the imperial court got him another big business, asking him to make ten telescopes, the price was relatively poor, and the imperial court only gave five thousand yuan, but Tang Zhou still did it.

And he knows very well that since the telescope is used in the military, he can't do it for others in the future, which is also the secret weapon of the Tang army, how can he let others have it at will?

In this way, when the trend of telescopes and glasses has passed, there will be a very interesting scene every time you go to the morning court, many ministers wear glasses to the court, because the eyes are between the ears and move down from time to time, and these ministers will often subconsciously use their fingers or lift or hold the glasses in order to be comfortable or see more clearly.

Every time Li Shimin was sitting on the dragon chair discussing things with the ministers, and when he saw this action of some ministers, he suddenly couldn't help but want to laugh, because he felt that people with glasses were really funny, very similar to the giant pandas in Shu.

And just after the trend of telescopes, Li Yuanyu, the king of Luoyang, hurriedly sent a pair of glasses to Liu Bai.

He had seen the telescope, and if it could be used well, it would definitely be beneficial to their career, but the telescope court would not allow him to do it, so he got a pair of glasses from Tang Zhou, he felt that the telescope was similar to glasses, so he was ready to let Liu Bai study it, if they could study the telescope, it would be very helpful for their future career.

And he believed that with Liu Bai's cleverness, he would definitely be able to study what the telescope was all about.

The capital is slowly returning to its former liveliness, but the weather is getting colder day by day, and autumn is deeper.

Autumn is a season that makes people easily sad, but not for Princess Chengyang, because she is in love, and for people who are in love, there seems to be no difference between any season, in their opinion, spring is poetic, summer is poetic, autumn and winter are also poetic.

They only have each other in their eyes.

Princess Chengyang couldn't extricate herself from her love, but she waited left and right, but she couldn't wait for her father's words, she was a little anxious, so she went directly to the imperial study to find Li Shimin after her father left the early dynasty.

After she saw her father, she was a little angry: "Father, women are not small." ”

Li Shimin was originally reviewing the folds, and when he heard Princess Chengyang's words, he was stunned for a moment, and then suddenly understood what was going on, and after he understood, he couldn't help but feel ashamed of his daughter's impulsiveness, how could a girl be so unreserved?

"What, you just want to get married so much?"

"Father, daughter...... Daughter ......"

Princess Chengyang was a girl in the end, and she was still a little shy when she was asked this question, but soon she looked at Li Shimin and nodded very seriously: "To be exact, my daughter wants to marry Du He." ”

Li Shimin sighed secretly in his heart, he really didn't understand that Du He had the good ones, but at this time he hadn't made a decision, and he didn't know whether to make the prince's power stronger.

In other words, he didn't know if the crown prince Li Chengqian would be able to inherit the Tang dynasty he had beaten down.

In the past two years, he was very disappointed by what the crown prince Li Chengqian had done, which was another reason why he wanted to vigorously support Li Tai, the king of Wei, who would not put his eggs in one basket.

But although the crown prince Li Chengqian made him a little disappointed, he still hoped that his son could cheer up, because Yi Chu's matter was very big, and a little carelessness could destroy the country he had conquered, why did the Sui Dynasty perish in a few decades, and it wasn't Yi Chu who made trouble?

If it weren't for Emperor Wen of Sui Emperor Yang Jian replacing the crown prince Yang Yong, how could Yang Guang become the crown prince, and how could the Sui Dynasty perish because of Yang Guang?

At this time, Datang was really booming, and if the situation was unstable because of easy storage, he really didn't dare to imagine what the future of Datang would be.

Li Shimin thought about the matter of the crown prince Li Chengqian recently, and it seemed that he was much more settled than before, and when he presented the telescope that day, he was really happy in his heart.

Thinking like this, Li Shimin was a little shaken, if Princess Chengyang could stand on the side of the crown prince Li Chengqian, and then let the crown prince Li Chengqian inherit the throne calmly, it would not be a good thing.

The emperor's heart is unpredictable, what he thinks about is not the happiness of his daughter, but the future of the entire Tang Dynasty, Princess Chengyang doesn't know this, she just wants to marry Du He as soon as possible, she looked at her father, with anticipation and eagerness in her eyes.

The moment he saw Princess Chengyang's eyes, Li Shimin's heart suddenly melted, even if he had to think about Datang, he still hoped that his daughter could be happy, at least he hoped that his daughter could be happy, live happily, and marry happily, that Duhe, he decided to think about it.

"Chengyang, it's the Mid-Autumn Festival in a few days, and then I will test that Du He, if he really has the ability to be worthy of you, I will give you a marriage on the spot, it's all right?"

Princess Chengyang's heart was pinching, but when she heard this, she immediately jumped up excitedly: "Is what my father said seriously?" Duhe is a capable person who will not let you down. ”

Li Shimin smiled: "My father is the Son of Heaven, haven't you heard of Jun Wu's jokes?" Since I promised you, I will do what I say. ”

--------------------------

East Palace.

Since Du He and Princess Chengyang were together, a few days have passed, but there has been no movement on Li Shimin's side, which makes the crown prince Li Chengqian, who was ready to wait and see what happens at the beginning, a little anxious.

The longer it drags on, the more likely it is to cause trouble.

"Mr. Du, didn't you tell Chengyang to ask him to urge his father?"

"His Royal Highness the Prince, his subordinates hinted to Princess Chengyang, but whether she went to the saint or not, the subordinates don't know."

The crown prince Li Chengqian's brows condensed slightly, and he couldn't help but sigh, and at this time, Du He was also a little anxious, marrying the princess as a concubine was not only for the prince Li Chengqian's position as the prince, but also for his Du family, so he must succeed.

It's just that this matter is not something he can decide, Li Shimin is willing to agree, the key is to see if he wants to support the prince Li Chengqian, but Du He didn't dare to say this to the prince, he was afraid that after saying it, the prince Li Chengqian would misunderstand, and he would blame him if he didn't marry Princess Chengyang, and if this thing really didn't work out, Li Shimin was only afraid that he would give up the prince, so he couldn't tell the prince.
