Capital Datang

Hearing Yuan Tiangang's words, not only Li Yin and others behind were stunned, but even Li Yexu stopped immediately, took a few steps back and asked hesitantly: "Old God... um~ Daoist Yuan, is what you said true? "

"Poverty Taoist never tells lies!" Yuan Tiangang saluted and said solemnly.

"Daoist Yuan, can a person's face also be changed?" Before Li Yexu could speak, Li Jingye who was beside him rushed to ask.

After hearing this, Yuan Tiangang explained with a smile: "The so-called face is actually the appearance of a person's life luck, so if the luck changes, the person's face will also change accordingly, but this change is very small. It's hard to see."

Hearing Yuan Tiangang's explanation, the hopeful look on Li Yexu's face increased greatly, and he immediately stood up and asked the other party to help him look.Cheng Huailiang and Li Jingye also surrounded him. As for Li Min, although he didn't quite believe it, it was related to Li Yexu's future, so he was also very interested. He stepped forward to hear what Yuan Tiangang had to say?Capital Datang 151

I saw that the other party looked at Li Yexu carefully, and at the same time, the fingers of his right hand were counting quickly.During this period, Yuan Tiangang's expression was very solemn, and it seemed that this kind of calculation was very mentally consuming, and in such a short moment, a slight sweat had already appeared on his forehead.

"Sure enough!" At the end of the calculation, Yuan Tiangang let out a long breath, and said a little tired and helpless, "Don't worry, Mr. Li, your appearance has indeed changed. As for Wei Guogong, Pindao will naturally explain it. !"

The uneasy Li Yexu immediately jumped up happily when he heard the other party's words.Cheng Huailiang and Qin Huailiang were also happy for him, they surrounded Ye Xu and punched him excitedly.But just when they were happy, Li Yin found that Li Jingye also walked in front of Yuan Tiangang with a look of anxiety on his face. He was about to speak, but Yuan Tiangang said again: "Don't worry, Mr. Jingye. The comments in the book, but now you are the same as Mr. Li. Your appearance has already changed, and in the future you will be ordered by generals who will open up territories."

Cheng Huailiang and the others were excited, and Yuan Tiangang's voice was not high.So they didn't hear it, but Li Yin, who had been paying attention to this side, heard it clearly, especially when he heard Yuan Tiangang say that Li Jingye was ordered to die in the army.The surprise in his heart couldn't be added, because as far as he knew, Li Jingye really rebelled against Wu Meiniang and died in the chaos.

"It seems that this old magician still has some abilities, and it doesn't all rely on fools. Is there really such a magical skill of face recognition in this world?" Li Yin muttered to himself.After Li Jingye heard that his fate had also changed, he immediately transformed into the second Li Yexu, jumping up and down happily, but he was different from Li Yexu.Cheng Huailiang and the others didn't know that Li Jingye had the comment of dying in the army, so they thought that he, as Yexu's brother-in-law, was happy for his uncle because of his 'excessive' excitement.

After venting his excitement, Li Yexu did not forget to thank Yuan Tiangang.After all, he had to rely on the other party to convince his stubborn grandfather.It just happened that Li Yin had the best chef and fine wine here, and Yuan Tiangang was his guest, so Li Yexu borrowed flowers to offer Buddha, and asked Li Yin to set up a banquet, and several people entertained Yuan Tiangang well.

Actually speaking, because of Yuan Tiangang's original comments.Li Yexu has suffered for so many years, if it were another person, it would be difficult to forgive Yuan Tiangang on the spot.But Li Yexu has always been a heartless temper, no matter who he is, he doesn't hold grudges against anyone, just now he was fighting to death, and the next second he may call you brothers, Li Yin and the others know this too , even everyone appreciates him the most.

Li Yexu and Li Jingye are considered to be the best drinkers among the crowd, but probably because they were too happy, they drank wine almost like plain water today, and they would not refuse anyone who came to them. Li Yin and the others succeeded once, and the banquet was only halfway through, and the two of them were lying on the table drunk.

After the banquet, Cheng Huailiang and Qin Huaiyu took the two drunks out and sent them back to their homes respectively. Yuan Tiangang just came back today, and he had something to ask Li Yin, so he stayed at his home that day.After the banquet was over, Li Yin and Yuan Tiangang came to their study, and after telling everyone to retreat, they smiled and said, "Daoist Yuan, why did you come to Chang'an so quietly, I didn't even know what to do if I hurt you?" Prepare, and almost let Ye Xu bump into the Taoist priest, it is really rude!"

"Hehe, Your Highness is serious. Pindao is just a wild crane. As His Highness, there is no need to prepare. As for leaving Dengzhou, it is because of Pindao's disposition that he doesn't like to stay in one place for too long. Time, and I was entrusted by my apprentice to report the problem of the steam engine to His Highness." Yuan Tiangang felt that Li Yin seemed to be more polite to him today, but he has long been a character of not being surprised, so there is nothing wrong with it. Special expression, still said with a smile.

Hearing that the other party came to report to him about the steam engine, Li Yin suddenly regained his energy. Last time, in order to solve the problem of the steam engine leaking, he sent people to Chang'an to take away a lot of fig tree gum. Now he doesn't know the effect. how's it going?Immediately, he asked eagerly: "Daoist Yuan, what did Yifan say, how is the steam engine now?"

"His Royal Highness, that kind of fig tree glue is indeed good, but in terms of wear resistance, it still can't meet the requirements." The first half of Yuan Tiangang's sentence made Li Yin happy, but the second half of the sentence was another basin of cold water Fortunately, he didn't finish his sentence, and the following news finally made Li Yin feel better.

"However, although the gum does not meet the requirements, it still has some effects. The steam engine improved by Yifan and sealed with gum can reach a maximum power of about five horsepower. However, because the gum is easy to wear and tear, this maximum power It can't be maintained for too long, and generally it can only be maintained at about three horsepower." Yuan Tiangang still said unhurriedly.The horsepower and power he mentioned were all new terms introduced by Li Yin after the invention of the steam engine. Except for the craftsmen who participated in the design of the steam engine, only Li Yin could understand it in the entire Tang Dynasty.

"Although the three horsepower is a little less, it is a good achievement to increase the power three times in a short period of time." Although Li Yin praised him, he still couldn't help frowning. Now is the initial stage of the steam engine, so the increase Tripling the power may seem like a lot, but it is actually not difficult. The more you increase the power, the more difficult it will be.

Yuan Tiangang has seen all kinds of life in his life, and he can clearly understand Li Yin's thoughts at a glance, so he still said with a smile: "Your Highness, don't worry, this time I come to Chang'an, besides telling you this, there is another very important thing. Something important needs to be done, and it has something to do with the steam engine."

"Oh, what's the matter?" Li Yin asked impatiently, and at the same time thought to himself, this Yuan Tiangang is good at everything, but he likes to play tricks, why don't he finish everything at once?

"Your Highness, although the gum of the fig tree is inferior in terms of wear resistance, we have tested countless materials before, and none of them is better than this gum, so I came to Chang'an this time just to find some Daomen. My friends can help to enhance its wear resistance, I think there are countless capable people in Datang, and I will definitely find a solution!" Yuan Tiangang said confidently.

In the era of the Tang Dynasty, compared with Confucianism and Buddhism, Taoism's influence was not weak at all. Even if the forces in Taoism were combined, the influence of Buddhism and Confucianism was only stronger than in recent years. However, Taoism has one of the biggest The shortcoming is that there are many sects, and there are at least thousands of schools, large and small. Although the theories of each school are derived from Lao Tzu's Tao Te Ching, the Tao Te Ching is broad and profound, and each has its own understanding. The developed schools of thought There are also all kinds of sects, and the disciples in the sect have their own strengths.

It is precisely because of this that the Taoist school is actually more like a place where a hundred schools of thought gather. There are all kinds of talents in the school, such as Sun Simiao who studies medicine, Li Chunfeng who plays mathematics, and Yuan Tiangang who is good at making friends. Wait, and because Taoism is popular in alchemy, gunpowder was first invented by those alchemists who are not afraid of death, and in the process of alchemy, Taoists accumulated a lot of chemical and physical knowledge, and even made many strange things. Strange, something that even Li Yin, a later generation, cannot understand.So when Yuan Tiangang encountered the problem of rubber wear resistance, he thought of his colleagues in the Taoist school and wanted them to think of a way.Capital Datang 151

After Li Yin heard Yuan Tiangang's idea, he also appreciated it very much, but when he heard about the wear resistance of gum, a flash of light suddenly flashed in his mind. At the time, it seemed that in order to increase the wear resistance of the rubber, something had to be added to the rubber, but it was a pity that no matter what happened to Li Yin, he couldn't remember what that additive was?

This made Li Yin very anxious. Although the additive was added to the rubber, if it was added to the gum of the fig tree, would it be effective?But that's always an opportunity, after all rubber is a kind of gum after all, so it's likely that the additive will work on other gums as well.

But everyone has a problem, that is, the more anxious you are, the less you can remember.Li Yin was almost thinking about it, but in the end he still had no idea. He hated him so much. Why didn't he study hard at the beginning? Now he finally realized the feeling of hating less when the book is used up?

Seeing Li Yin sweating profusely, Yuan Tiangang wanted to ask several times, but was stopped by Li Yin.When he finally bowed his head in frustration, Yuan Tiangang said: "Your Highness, as soon as Pindao entered Chang'an, I heard that His Highness is preparing for a military academy, and when I was in the city, I also met Sun Simiao and Sun Daoyou, I heard from him that His Highness will set up a Datang Medical College dedicated to the promotion of medicine. Such an act of benefiting all people really admires Pindao, but Pindao also has an idea because of this, and I implore His Highness to help a little bit. !" (To be continued.
