Holding urine can travel thousands of miles, but it is difficult to move an inch.

Li Er stayed in the toilet for a long time this time, and Wang De was a little anxious.

"Is the saint well?" Wang De asked.

Li Er rolled his eyes.

"How long have I been squatting? You keep asking me if I'm okay, I'm so good, I'm finally comfortable, melon seed chocolate strawberry ice cream is delicious! Li Er said.

The corners of Wang De's eyes twitched, he was strained until he ate it, and said it was delicious!

After a short time, Wang De heard a groan and groan.

"Sage, what's wrong?" Wang De exclaimed.

"It's okay, my leg is numb." Li Er said.

Wang De: "......"

"Do you want to find an imperial doctor, you have to pay attention to diarrhea." Wang De said.

"Afraid of what? I also drank horse blood back then, isn't it still good? This little ice cream won't make me a big deal! Li Er said.

Wang De sighed, it's a good thing to be dissatisfied, but you still have to take care of your own physical affairs, otherwise, it's too late to regret it later.

"Let's let the imperial chef get some food for the saint to warm the spleen and stomach, don't see a doctor and take medicine, you always have to eat." Wang De thought to himself.

Li Er came out and couldn't help complaining: "The last toilet is so uncomfortable, my legs are numb, I have to control the time in the future!" ”

Wang De asked tentatively: "Sage, does His Royal Highness the Crown Prince have a lot of research on these things, why don't you let him improve the latrine?" ”

"Nonsense! I haven't said that he is not, you have given me a bad idea, he is a prince, he is not good at learning the way of governing the country, the art of controlling people, and he is funny every day, I will never agree! Li Er said.

Wang De rolled his eyes, I don't know who said that Li Chengqian's potatoes are a great invention, which can ensure that the Tang Dynasty is worry-free for a hundred years, who eats ice cream and eats diarrhea!

Of course, since Li Er said so, he didn't have much to say.

The two walked back.

Li Er said coldly: "You just said that Gao Ming can make me more comfortable to go to the toilet?" ”

Wang De said: "The minister is just guessing privately, it can't be counted, maybe His Royal Highness the Crown Prince doesn't have any good way, after all, the toilet is really not very elegant." ”

"In this way, you go to him and ask him to do this, and you say that you want him to help, not to mention that my leg is numb from the stewed in the toilet, and you want him to do this." Li Er said.

Wang De had to say with tears in his eyes: "Yes." ”

came up with an idea to put himself in, who did he recruit to provoke whom?

Of course, Li Chengqian had to agree to this matter, and it was not interesting to renovate the toilet, and if Li Chengqian did not agree, he could not force it.

After all, what the sage said was very clear, this was what he wanted Li Chengqian to do, not what the sage meant.

Prince's Mansion.

"Wang De, why are you here again? Don't you understand that there is no ice cream? Li Chengqian said.

"No, no, this time I have a reluctant request, I want His Highness to renovate the latrine, which is more suitable for me to go to the toilet." Wang De said.

Li Chengqian could see at a glance that this must be Li Er's sand sculpture idea, using Wang De to block the gun, yes, the dignified emperor, let the prince do this kind of thing, it is unreasonable!

However, he didn't want to let Wang De go like this, Li Chengqian said: "This matter is too simple, I can draw it for you now." ”

Wang De was overjoyed, he didn't expect this matter to be completed so easily!

He hurriedly said: "His Royal Highness the Crown Prince, hurry up and draw it!" ”

Li Chengqian went to the study, and Wang De followed.

"Xiao Cui, polish the ink for me, I want to write something." Li Chengqian said.

Xiaocui was pleasantly surprised, Li Chengqian is going to write poetry! This is a once-in-a-lifetime good thing, and many people are waiting for Li Chengqian to write poems!

She hurriedly polished the ink for Li Chengqian, and laid out the paper by the way.

Li Chengqian picked up a brush, dipped it in ink, and began to write something on the paper.

Xiao Cui and Wang De opened their eyes wide, watching Li Chengqian's movements, stroke by stroke, he didn't seem to be writing, but drawing.

Wang De knew that what Li Chengqian told him before was painting.

Li Chengqian first drew a sign of a men's toilet, and after he finished drawing, he felt good about himself.

"What is this?" Wang De asked.

"This is the logo of the men's toilet, you see, isn't it very vivid?" Li Chengqian said.

Although Li Chengqian, a stickman, only has a few strokes, he draws a man standing straight, which is indeed very vivid.

Xiao Cui said: "I didn't expect His Highness to paint well!" ”

"You're going to be a sycophant!" Li Chengqian said.

Obviously, Li Chengqian misunderstood what Wang De meant.

Li Chengqian continued to paint, and she drew a sign for a women's toilet.

Then, Li Chengqian looked up at Wang De and continued to paint.

He drew a one-legged man.

"It's your logo." Li Chengqian said, "One leg is missing." ”

Wang De: "??? ”

"Negative sentiment from Wang De, +188"

Sure enough, it was convenient for him, Wang De wanted to thank Li Chengqian's eighteenth generation ancestor!

Li Chengqian frowned: "What's the matter, why aren't you happy?" Isn't it a thing to be happy that you eunuchs finally have your own thatched hut? ”

Wang De: "You misunderstood what I meant, I mean, it's more comfortable when you go to the toilet, it's not a place to go to the toilet, besides, we go to the men's toilet." ”

"Okay, let's not play tricks on you, you go back first, and wait for my good news." Li Chengqian said.

"Then wait for the good news from His Royal Highness the Crown Prince." Wang De said.

Wang De left, and Xiaocui was a little worried.

"His Royal Highness the Prince, how are you going to renovate the thatched house? This place is already dirty. Xiaocui asked.

"It's okay, I know what to expect." Li Chengqian said.

Anyway, everything can be done according to the toilet of the later generations, which is not difficult.

The first thing he thought of was the toilet, and the toilet was very easy to make, ceramic was a very common material, and he could easily make a ceramic toilet.

He told Yan Lide about the idea of the ceramic toilet, and Yan Lide looked at the drawings drawn by Li Chengqian casually and was surprised.

This thing is really wonderful, of course, he doesn't know much about the flushing system of this thing, Li Chengqian's introduction, just said the flushing device in the toilet, but he didn't draw this thing.

And the thing that made Yan Lide speechless the most was that Li Chengqian actually attached a sentence behind him.

"I don't know what to do with the flush, you can figure it out for yourself."

"Negative sentiment from Yan Lide, +128"

"Yan Shangshu, how should this be? This flushing thing doesn't seem to be easy to do! The principal asked.

"It's okay, the idea of the toilet is very good, and we can make this flush system with a little thought." Yan Lide said.

The main personnel of the Ministry of Engineering held a small meeting to discuss what to do with the flushing device.

In the end, they came up with a solution, that is, to use the height of flushing to make the water storage bucket higher, and it is normal to slightly modify the toilet painted by Li Chengqian.

"Very well, let's start trying out this toilet right away." Yan Lide said.

The official kiln received an order from the Ministry of Industry and began to make it, except for the shape that they did not understand, the production process was very easy.

The toilet bowl is not made as a whole, but is made of separate parts, which greatly simplifies the production process and processes.

After the assembly was completed, the flushing system was immediately tested, and sure enough, the flushing effect was very good when the height was raised.

Yan Lide was very satisfied.

"The main thing is that this shape under the toilet bowl is very good, I don't know why, as long as you flush it, you can always flush out the filthy things and leave clean water." Yan Lide said.

Of course, they can't really test with, they use ink, black ink, and it washes off every time.

Everyone was amazed and sent the first toilet to Li Chengqian, Li Chengqian was also very satisfied with this toilet, which is a very good improvement, although the button flushing was changed to a lever.

It also has to be filled with water from the bucket above, which does not affect its advanced nature.

The next morning, Li Chengqian sat on the toilet, looking at the new newspaper, as if he was in a different world, isn't this what people will do every morning in the future?

It's just that many people have replaced newspapers with mobile phones, and the time spent squatting on the toilet has greatly increased.

A lot of people are interested in the toilet, and there is a long queue in front of the hut, and everyone wants to try what it's like to sit and.

There are even people who simply want to go in and sit down, and after entering, they sit on it, and pick up the newspaper that Li Chengqian has read.

They feel very good, Li Chengqian shook his head, these people are really speechless, it's like they have never seen the world!

The toilet was naturally sent to Li Er, and the people in the Ministry of Industry were very powerful, and they directly gave all the credit to Li Chengqian.

Although Li Er knew the specific production steps, Li Chengqian did make a lot of contributions, and he didn't say anything.

Li Chengqian sent Li Er a pair of myopic glasses by the way.

Staying up late all year round to review and review, Li Er's eyes have long been short-sighted, but he doesn't have this concept, and his myopia is not too serious, so he doesn't care about it.

"What is this?" Li Er asked.

Wang De said: "This is the myopia glasses specially made for you by His Royal Highness, crystal, he said that it can make the saint see more clearly." ”

"Oh?" Li Er tried.

He didn't see it very clearly.

"It doesn't work." Li Er said.

Wang De: "......"

That's embarrassing......

Of course, I can't see clearly, and Li Chengqian didn't test Li Er's myopia degree, how can he get good myopia glasses?

However, it is not difficult to test the degree of myopia, so if you can't do it, you can make a few more pairs of glasses, and there is always a pair that suits Li Er.

Li Chengqian sent Li Er myopia glasses, not because he meant to get up for a while, but because he received a table to test his eyesight.

It wasn't expensive, and he wasn't pleasantly surprised, it just gave him a little more urge to make glasses.

Wang De is here.

"Your Royal Highness the Prince, you're playing smashed! The saint said he didn't see it very clearly. Wang De said.

"It's normal, I didn't test his eyesight and of course he won't get the right glasses for myopia." Li Chengqian said.

"What's going on?" Wang De was surprised.

"Just take me to him, I'll show it in person." Li Chengqian said.

After a short time, Wang De took Li Chengqian to see Li Er.

Li Chengqian said: "Father, please cooperate with me after a while, you will do whatever I say." ”

Li Er was puzzled: "What are you going to do?" ”

"Test your eyesight and then get you glasses for myopia." Li Chengqian said.

Li Er thought about it, the eyes that Li Chengqian made before were actually a little useful, but the effect was not obvious.

Now Li Chengqian wants to make the right glasses, to be honest, he is still looking forward to it.

"Yes, I will cooperate with you." Li Er said.

Li Chengqian went to the back room to change into a white coat, black-framed glasses, and took out a whip.

He walked out, hung the eyesight test sheet in the right place, and pointed the whip at the largest E.

Li Er was a little confused, he looked at the E, and then at Li Chengqian, he didn't know what to say.

Li Chengqian sighed and said, "Father, cover one eye, and then, say that the three forks of E refer to that side, up and down, left and right, you know." ”

Li Er was very interested in this matter, and he covered his left eye, more than a right.

Li Chengqian continued to ......

In a short time, he tested the myopia degree of Li Er's eyes, which was converted to more than 100 degrees.

More than 100 degrees is actually not very high, you just need to protect it, of course, you can really see more clearly with glasses.

At Li Erdu's age, the muscles of his eyes will become more and more relaxed in the future, and he does not need to be afraid of rising degrees.

Maybe it will gradually recover in the future, and it will not be presbyopia.

Myopia surgery in many hospitals is very bad for patients, so it is better not to do it.

Many doctors are short-sighted, of course, some have to say that these doctors are short-sighted for work.

Some surgeons must be nearsighted.

"Okay, father, your myopia is not serious, you usually review and review, and if you look at it for an hour, you will go out to see the green mountains in the distance, and it will not be serious in the future." Li Chengqian said.

His tone was really like that, and Li Er nodded subconsciously.

"Very good, Wang De. Do you need me to test your eyesight? Li Chengqian asked.

"No, you don't." Wang De hurriedly said.

After the saint tested his eyesight, he followed the test, what is this like!

"Father, you just wait for me to bring the glasses later." Li Chengqian said.

"Okay, I'm looking forward to it." Li Er said.

After Li Chengqian went back, he asked someone from the Ministry of Industry to make glasses.

Many people came to Li Chengqian again to discuss the toilet matter, especially many who were doing business, and they were very excited to see this business opportunity.

It's definitely very popular, everyone likes to enjoy it, and there's nothing more comfortable than sitting in the morning.

"Lu Zihou, this matter will be handed over to you, the general dealer of the toilet is you, and you will take care of all kinds of things." Li Chengqian said.

"Good!" Lu Zihou was very excited.

Li Chengqian sighed, you can make money by doing anything!

He suddenly wondered what would happen if he made more than 50% of Datang's total wealth.

There is still a long way to go, and he decided to continue to find some ways to make money, and his eyes couldn't help but focus on the dart game.

The dart bureau is the express delivery in ancient times, and Li Chengqian decided to integrate the dart bureau and make a new network where people can buy things at home.

The name is called Ding Ding Dong.
