Datang romantic little landlord

Li Wangyou directly raised his middle finger at the group of dudes: "Before you came, Uncle Cheng and Uncle Yuchi had just left, and what they said was the same as your elder brothers!"

Cheng Chumo, Cheng Chuliang, and Cheng Chubi looked at each other, then at the Yuchi twins, and couldn't help laughing.

"Ziyou, this means that the tiger father has no dogs and sons, fighting against brothers, and fighting with father and son!"

Li Wangyou's eyes almost rolled to the sky, what kind of mess is this?This uneducated pig brother!

He didn't bother to pay attention to Cheng Chumo, and turned his head to look at Fang Yiai and the others: "Tell me, who are you betting with again this time? What are you betting on?"

The dandies laughed loudly: "Naturally, they are the family members of the five surnames and Qiwang. Besides them, where else are fools rushing to give money to my brothers? Yesterday, my brothers ran into those bastards in Pingkangfang , actually dared to speak out to humiliate Ziyou. Brothers started arguing with them, so they made a bet."

Prince Qiao from the Taiyuan Wang family, Cui Daogu from the Qinghe Cui family, Cui Hong from the Boling Cui family, and Lu Siyang from the Fanyang Lu family, as Li Wangyou's title gradually increased, they did not dare to be with Li Wangyou again. I bluffed in front of worry.

Several patriarchs with the five surnames Qiwang were expelled from the court last year by Li Er on the pretext of the gold loss case, and these aristocratic family members died down for a long time.

But the aristocratic family's influence in the court is still huge, and this aristocratic family's son will naturally not become a good baby because of this.Li Wangyou had heard from the dandies a long time ago that in Chang'an City, there were still many conflicts with these aristocratic families.

"What did you bet on?"

"Hehe, I didn't gamble. You know that my brothers are poor and can't afford much copper coins. Besides, gambling is too vulgar, so I didn't gamble." Cheng Chu laughed silently.

Li Wangyou nodded, knowing that dudes are also cash-strapped.

Although Li Wangyou "made a fortune", by the way, even the big bosses who were close to him also made a lot of money.But except for the two brothers Du He and Du Gou, in other families and mansions, it is not the turn of these dandies to be the masters of the house.

Therefore, they still rely on the little "pocket money" given out at home every month.

Of course, it is pocket money, but if it is put in the homes of ordinary people, it is already a huge sum of money, but for the dandies, the expenses are also high, so these dandies are actually "poor ghosts", and they can't take much out of their pockets. A hundred copper coins come.

"Then what did you bet with Wang Ziqiao and the others?" Li Wangyou asked curiously.

"Hey, it's just a bet on dozens of stunning maidservants." Fang Yiai rushed to answer: "Speaking of which, the little nurses in Xiehe Hospital are quite different in appearance, which is better than nothing."

When Li Wangyou heard this, his nose almost crooked!

Ma Dan, these bastards are really annoying!

Li Wangyou suddenly felt embarrassing, and led a group of disciples to test the vacuum pump here, but Cheng Yaojin, an old rascal, and the dudes actually "sit back and enjoy the benefits"!

There are those who win the horses, and those who win the beautiful maids... Mo Dan, for a moment, Li Wangyou was so embarrassed that he quit!

It would be best to let these bastards lose!

Of course, he was just thinking about this kind of thing.

"Ziyou, you must not lose, the brothers' happiness depends entirely on you." Cheng Chumo showed his old face, and did not forget to remind him again and again.

After angrily driving away all the dudes who came to inquire about the news, Li Wangyou looked up to the sky and sighed.

"Heaven will send a great mission to the people, and you must first work hard on your heart and mind... I really am exhausted!"

Niu Wu, who was at the side, twitched his face twice, complaining about his husband crazily in his heart, how could such a lazy character who was so lazy to the bone have the nerve to say this?

Li Wangyou sighed, turned his head and continued to study with Yan Liben and others on how to make a vacuum pump.

The Magdeburg Hemispheric Test is not difficult to say.

Two hollow copper hemispheres, filled with water and joined together, with a layer of oil-soaked leather in between to allow the two hemispheres to be completely sealed.

One of the hemispheres has a connecting tube for the vacuum pump and a valve to shut it off.

After using a vacuum pump to pump out all the water in the hemispheres, the two hemispheres will be squeezed together by the surrounding atmosphere.

Su Changqing, the "Bone Spirit", when he was traveling in Germany, also went to the Deutsche Museum in Munich to visit the two hemispheres that Curic used for experiments.

Two copper hollow hemispheres with a diameter of [-] centimeters are not difficult at all. Li Wangyou has already ordered craftsmen to make them.

But to repeat the Magdeburg hemispheric test, the most difficult thing is the production of the vacuum pump.

The mayor of Magdeburg, Otto von Glick, is also a German physicist. He invented the piston vacuum pump, which made the Magdeburg hemispheric experiment come true.

Li Wangyou wanted to repeat this historic experiment in Datang, but he hit a snag on how to make a piston vacuum pump.

Li Wangyou knows the principle of the piston vacuum pump, relying on the piston in the vacuum pump and the cylinder to make reciprocating motion to suck in and exhaust gas.

But it's one thing to know the theory, and quite another to actually make it.

In any case, the vacuum pump can be regarded as a modern industrial product, but it is not easy to replicate it in Datang.

Li Wangyou, Yan Liben and others have studied for two or three days, but they have no clue.

This naturally made Li Wangyou very depressed.

He didn't understand. When reading time-travel novels in later generations, it's so easy for those pig feet to create the Magdeburg hemisphere experiment. How come it's so difficult for him to plagiarize and cheat?

(There is another chapter, which will be uploaded in two hours. By the way, I would like to complain about WPS, but I actually turned off the voice reading function... Laolong is used to reading every chapter by voice, checking for typos. Without this function, it is really troublesome It is estimated that there are a lot of typos in the last few chapters, please bear with it!)

946 Royal College Hemisphere Experiment

Time passed by, and ten days later, the Datang Royal Academy, located on the other side of the Gan River in Dingzhou Village, became lively.

Nuo University's academy is full of nobles in various costumes today.

Hearing that Li Wangyou is going to show His Majesty and the officials today what atmospheric pressure is, the relatives of the officials are all very itchy.

Such a lively scene, who wouldn't want to watch it?

Unable to bear the pleadings of the female relatives in the mansion, Fang Xuanling and several other state officials took the lead and came forward to invite Li Erzou. Today, all officials are allowed to bring their relatives to the academy to watch the grand event.

Li Er naturally nodded in agreement, and he himself also brought along Empress Changsun, Concubine Yang and other harem concubines.

It is also fortunate that when Li Wangyou designed the academy, because there was no shortage of land and copper coins, the academy was built extremely spacious, otherwise it might not have accommodated so many people.

"Ziyou, why are you so haggard today? Are you prepared for that experiment? I'm looking forward to it!"

Li Wangyou stared at a pair of panda eyes, which were full of bloodshot eyes, and said with a weary and wry smile: "Uncle, fortunately, my nephew led Liben and the others yesterday, and finally gave the device needed for today's experiment to me. It's made."

He really tried his best this time.

Originally in the Tai Chi Hall, I said a time of ten days, thinking that the time was ample.

Who knows how difficult it is to actually start to build that reciprocating piston vacuum pump.

Thanks to Li Wangyou's understanding of its principle, Yan Liben is a rare "engineering" talent in the Tang Dynasty, and with the assistance of a group of skilled and experienced craftsmen from the general supervisor, the vacuum pump was turned on on time. Made it.

Even so, Li Wangyou, Yan Liben and others stayed up all night and were extremely tired.

Regarding this, Li Wangyou could only sigh silently in his heart. Sure enough, don't pretend to be a man, and you will be struck by lightning!
