Datang romantic little landlord

This group of dudes don't think it's a big deal just to watch the excitement.

What's more, the vending machine that Li Wangyou mentioned sounds quite interesting. If so, how can Chai Lingwu be allowed to escape.

Only then did Chai Lingwu realize that his own mouth was about to cause trouble just now, and he had a vague feeling that his beloved Wang Youjun's copybook would not be kept.

He cried with a sad face: "Brothers, just think I didn't say it, okay? I was wrong, I apologize to Ziyou and everyone, today Pingkang Fang treats guests, the little ladies in the painting building, brothers, please feel free to order, okay? "

Fang Yiai, Cheng Chumo and others looked at each other, and replied in unison: "No! Today's bet must be played, and I will be a witness!"

Chai Lingwu can't wait to give himself a mouth, call you a cheap mouth, why are you provoking Li Wangyou so well?

Li Wangyou smiled brightly when he saw the dudes forcing Chai Lingwu to accept the bet.

"Wahhahaha, brother Lingwu, give me three days to prepare Wang Youjun's copybook, and I will convince you to lose."

In a moment of excitement, he even imitated that old man Cheng Yaojin's laughter.The three brothers Cheng Chumo couldn't help squinting at him, wanting to see what's wrong with this guy, but imitating his adult's creepy laughter.

Li Wangyou's words made Chai Lingwu feel like a concubine, feeling that life is simply gloomy.

"Ziyou, brother, it's not easy for me to get this Wang Youjun's copybook. This is my heart." Chai Lingwu still wanted to struggle.

"Well, I see, I will take good care of it, thank you Brother Lingwu."

Li Wangyou replied as a matter of course, Chai Lingwu had the urge to spurt blood with his appearance of winning.

It's not nice to meet people!Chai Lingwu looked up to the sky and sighed, he didn't read the almanac when he went out today, and he really memorized it to the extreme.

Li Wangyou, who was dazed by the sun, regained his energy and quickly went to the last two noble houses to give gifts. He didn't even bother to take a sip of tea, so he said goodbye and left.

As for Cheng Chumo and the others' invitation to go to Pingkangfang for a drink, Li Wangyou naturally didn't bother to go. He was in a hurry to find a craftsman to make a vending machine so that he could win Chai Lingwu's copybook.

In this regard, Chai Lingwu had no choice but to raise his two middle fingers to Li Wangyou to express his "excited" mood, and at the same time secretly prayed in his heart that Li Wangyou was bragging.

The reason why Li Wangyou was so confident in betting with Chai Lingwu was, of course, that it was not difficult to make a machine that automatically sells drinks.

When he was studying e-commerce, when the professor talked about the impact of vending machines on modern business, he said that as early as the 1st century AD, the ancient Greeks had created a device for automatically selling holy water, which was the earliest in the world. vending machine.

Li Wangyou was very interested in this matter at the time, and even went to the library to check the information and saw the restoration picture of the vending machine.

The principle of the vending machine of the ancient Greeks is very simple. Put coins from the coin slot, and the coins fall into the small plate in the instrument. The small plate is connected to a lever. Through the principle of the lever, it drives the valve in the holy water bucket in the device.

After the valve is opened, holy water flows out automatically.

And the small plate containing the coins keeps falling, tilted at an angle.Until the coin slides off the small plate, the lever resets and the valve closes automatically.

This vending machine selling holy water was regarded as a miracle by the ancient Greeks and caused quite a stir at the time.

So when Li Wangyou heard that Chai Lingwu actually wanted to bet with him, he naturally laughed so hard that he almost lost his eyesight.

He had long been salivating over Chai Lingwu's and Wang Xizhi's copybooks, but he didn't expect this stuff to come to his door automatically, good man!

Saying goodbye to the dudes, Li Wangyou led Niu Wu and rode directly to Yan Liben's residence.

If the master has something to do, he naturally needs his disciples to do it for him.

Yan Liben, as the young supervisor, is also good at craftsmanship, what an ingenuity.

Li Wangyou only knows the principle and general appearance of the beverage vending machine, and Yan Liben's help is naturally needed for how to realize it.

What's more, there are all kinds of skilled craftsmen in the general prison, who are good at making strange devices.This drink vending machine was designed, and it also needs to be built by craftsmen like the supervisor.

In the hall of the Yan Mansion, Yan Liben was chatting with Ma Zhou as a chess player, chatting about his master, and all the commotions that have happened in Chang'an City in recent days.

Of course, Li Wangyou didn't forget his two disciples for the air-conditioning window, and sent them to install it early in the morning.At this time, it was quite cool in the hall of Yan Mansion.

"Brother Bin Wang, the teacher is really very human. When you look at the air-conditioning window, you don't need manual work. Just dozens of porcelain bottles with transparent ends can blow out cool wind. It's amazing."

"Yes, sir, despite his young age, he is a scholarly genius. The more he learns from the master, the more he feels that the master is unfathomable, and he often does amazing things."

"Brother Bin Wang said that a certain artist was originally an idiot, but he wanted to be a teacher because of the master's amazing sketching skills. But he didn't expect that it was not only the painting skills, but also the master's whimsical ideas. It is a real treasure house, and I am very grateful to be able to study under my teacher."

When the two were sighing, they heard that the servants at home came to report that Mr. Huxian and his teacher had come to visit.

This surprised both of them, they ran out barefoot without even having time to put on their shoes.

"Master, why do you have time to come to the disciple's house today? Please come in quickly, please come in quickly." Yan Liben was overjoyed, and he and Ma Zhou hurried forward to salute.

Li Wangyou didn't expect Ma Zhou to be there, so he couldn't help laughing: "It's just right that King Bin is here, I need you two for help today as a teacher..."

385 What a coincidence

Yan Liben and Ma Zhou invited Li Wangyou to sit in the hall.

"Teacher, if you need the disciples to help you, please tell me clearly."

"Liben, get the pen and ink, and I'll draw a blueprint for you two to see."

A servant of the Yan family brought paper, ink, pens and inkstones, including several feather pens.

Yan Liben and Ma Tuesday had naturally seen this quill in Li Wangyou's mansion, and found it very interesting after trying it out.Then I also learned how to make it from Li Wangyou, and made some after returning home.

However, as a hard pen, this feather pen has not been widely spread in Chang'an City for the time being. The main reason is that Tang people are not used to it.

The posture of holding a writing brush is naturally completely different from that of a hard pen, and the scholars of Datang have never touched a hard pen, so naturally they have no way to start.

Even if you forcefully change your writing posture, the written characters are not very beautiful, and naturally no one wants to use them.

Later generations wrote beautifully with a hard pen, but writing with a brush is probably a mess.But I can write brush characters, but I may not be able to write well with hard pens.

Nowadays, only a few people in the Tang Dynasty have tried to learn to use the quill pen. On the contrary, Li Chengqian and Li Tai, the two little guys, felt that it was much easier than using a brush after getting in touch with the quill pen, and they studied it very seriously. Words are the best.

This is quite normal. Asking an eight or nine-year-old child to hang his wrist to write with a brush is indeed not as easy as writing with a hard pen.

But Li Wangyou didn't care about this, anyway, he made this quill pen just for his own convenience, whether other people like to use it or not has nothing to do with him.

Picking up a quill, Li Wangyou began to sketch patterns on the paper. Yan Liben and Ma Zhou hurriedly stood behind Li Wangyou, curiously looking at what their teacher was drawing.

"Teacher, what is this cabinet for? Why are there so many traps inside?" Yan Liben asked in puzzlement as he looked more and more confused.

While drawing a picture, Li Wangyou explained: "This is an mechanism that can sell drinks automatically. No manual labor is needed. Just put in copper coins, and drinks can flow out of it."

"Eh? It still has such an effect? ​​How can it be done?" Ma Zhou became interested and hurriedly asked.

Li Wangyou pointed to the drawing and began to explain the key points to the two of them. Yan Liben and Ma Tuesday nodded and applauded.

"Wonderful! In this way, as long as you set how many copper coins you need to put in, a fixed amount of drinks can flow out, haha, I understand! The teacher is really powerful, and such an exquisite mechanism can be figured out." Yan Liben clapped his palms laughing out loud.

Li Wangyou couldn't help but blushed when he praised him, hehe, he just copied the wisdom of the ancient Greeks, so it's a bit embarrassing to be praised by Yan Liben like this.
