Datang romantic little landlord

But these words were heard in the ears of everyone, but they were like a fairy tale, unbelievable, and it caused a burst of exclamation.

Fortunately, everyone is now convinced that Daozu is really Li Wangyou's master, so although these words are difficult to accept, no one doubts their authenticity.

"Ziyou, what do you mean, the dynasty you call Tubo is on this plateau?" Li Er asked.

"Yes, that's right."

"Then what's so special about Tubo that it can become my Tang's confidant?" Li Er asked puzzled.

The reason why Li Wangyou introduced Tubo to the monarchs and ministers of the Tang Dynasty so solemnly was because it was as strong as the prosperous Tang Dynasty in history, and the only opponent who had no choice was Tubo.

Stronger than Li Er, but he can only marry the princess and get married to maintain a short-term peace between the two sides.

Historically, even Chang'an in the Tang Dynasty was captured by the Tubo people twice.

During Gaozong's reign, Tubo captured the eighteen states in the Western Regions of the Tang Dynasty, and the Tang Dynasty was forced to abandon the four towns of Anxi.

In the third year of Tang Zongzhang, during the Battle of Dafeichuan, Xue Rengui, a famous general of a generation, encountered Waterloo, and the Tang army was raided by the Tubo army, causing all casualties.

During the Anshi Rebellion, Tubo occupied Chang'an for half a month.

Although he was expelled from Chang'an by Guo Ziyi, most of the southwest border of the Tang Dynasty was occupied by Tubo.

It can be said that Tubo was almost invincible against Datang because of the geographical advantage of the plateau, which caused Datang to suffer repeatedly and had nothing to do.

Naturally, Li Wangyou didn't want to let this kind of thing happen again, so he took this opportunity to solemnly introduce Tubo to Li Er and the others.

"Uncle, my lords, in the eyes of my nephew, Tubo is a country that threatens the Great Tang like a tiger. Tubo is like a sharp knife on my Tang's back, and it will stab Tang at any time. "

Hearing this, Li Er frowned slightly, before he could reply, he heard Cheng Yaojin and Yuchi Jingde beside him shout loudly.

"Zhu Zi'an dare! Can't I think that Tang Dynasty is a soft persimmon? Then what kind of bullshit Tubo, can it be better than the Turkic people? Ziyou, I don't believe you!"

"Don't worry, Your Majesty, if that Tubo dares to offend Tianwei, he will surely crush its balls!"

Li Wangyou smiled wryly and shook his head: "Uncle Cheng, Uncle Yuchi, if Tubo were so easy to deal with, my nephew wouldn't say it was Datang's confidant..."

Cheng Yaojin said with a disdainful face: "How difficult can a mere Tubo be to deal with? Can it be stronger than Turkic people? Ziyou, don't lie to me!"

"Uncle Cheng, when it comes to the fighting power of Tubo, it is naturally not as good as the Turkic people, let alone my Tang cavalry." Li Wangyou replied.

Strictly speaking, the combat effectiveness of Tubo is not as good as that of the Tang army.

In history, the first war between Tubo and Datang occurred in the autumn of the 12th year of Zhenguan. After Tubo annexed Tuyuhun, the Songzhou battle broke out with the Tang army in Songzhou.

Before the main force of the Tang army, Hou Junji, led a large force, Niu Jinda, who was the vanguard of the Tang army, had already defeated the Tubo army.

Songtsan Gampo feared the Tang army, led the Tubo army to withdraw from Tuyuhun, Dangxiang, Bailanqiang and other places, and sent envoys to apologize.

The Tang Dynasty and Tubo came after, and during the war and for more than 200 years, Tubo's main problem was that once Tubo was defeated, it would immediately retreat to the plateau.

The Tang army attacked the Qinghai-Tibet Plateau three times, but all failed due to altitude sickness and weather.

This made it possible for Tubo to attack Datang, and retreat to the plateau at most if it lost, but it was difficult for Datang to counterattack Tubo.

Historically, there was only one who could be a thief for a thousand days, and there was no one who could guard against a thief for a thousand days. Therefore, it was normal for Datang to suffer losses from Tubo every time.

Naturally, Li Er and the others did not understand these situations.

Cheng Yaojin was puzzled and asked: "Since that nonsense Tubo can't beat my Tang cavalry, why are you so worried? Why are you so worried about Tubo? Are you kidding me? ?”

Li Wangyou was speechless, and could only point to the plateau on the map and explain: "Couldn't Uncle Cheng forget? I said before that the Qinghai-Tibet Plateau where Tubo is located is more than 3000 meters high?"

"Well, so what?" Cheng Yaojin still didn't understand.

"Does Uncle Cheng know about miasma?"

The miasma in Li Wangyou's mouth actually refers to altitude sickness.

As early as the Han Dynasty, Huaxia was aware of the existence of altitude sickness and called it miasma disease or miasma disease.

In the hot and humid environment of the southern jungle, the poisonous gas produced by the decay of animals and plants is also called miasma.

Although the names are the same, according to doctors, miasmas in different regions correspond to different diseases.

Cheng Yaojin and others were slightly taken aback when they heard the words: "Ziyou, what do you mean, there is also miasma on the plateau?"

Li Wangyou nodded affirmatively: "To be precise, it should be called altitude sickness. This is also the knowledge that Master taught me."

Li Er asked, "Ziyou, tell me in detail, what does altitude sickness mean?"

"Uncle, you have also seen the academy hemisphere experiment my nephew did today, and you should be able to understand what my nephew said before, the air is not empty."

Li Er nodded: "Yes, I understand this now. I still remember that you said in the Tai Chi Hall that air is mainly composed of oxygen and nitrogen, and oxygen is the source of our life support."

Li Wangyou admired Li Er's good memory very much. Before that, he popularized science like this in front of all the officials.

He was not in a hurry to answer Li Er's questions, but ordered the old housekeeper Li Heng to fetch a crystal cup.

In the Hangzhou Museum of later generations, there is an exhibit. After seeing it, many tourists will think that the museum made a mistake and took a modern glass as an exhibit.

In fact, the cup, which is almost the same as the modern glass, is a crystal cup from the Warring States Period.

During the Warring States period, crystal cups could be polished manually, and so can Datang.

The crystal cup in Li Wangyou's mansion was made by the craftsman he asked the prison to follow the shape of the glass cup of later generations.

He took out the torch, lit a candle and put it on the table, and put the transparent crystal cup upside down on it.

"Uncle, gentlemen, the oxygen in the air is the root of our breathing and survival. And this candle also needs oxygen to burn. If the oxygen in the cup is exhausted, the candle will extinguish itself."

Accompanied by Li Wangyou's words, the flame of the candle in the crystal cup flickered a few times, and then extinguished itself.

This was just a very simple burning test, but Li Er and the others couldn't help but widen their eyes, their faces full of disbelief.

Cheng Yaojin impatiently picked up the crystal cup, lit the candle again, and put the crystal cup upside down.

Tens of seconds later, the candle quietly went out again.

"Straight mother thief, there is such a thing!" Cheng Yaojin subconsciously opened his mouth and took a few deep breaths, fearing that he would die due to lack of oxygen.

He turned his head to look at Li Wangyou again: "Ziyou, this kind of oxygen is amazing! But what does it have to do with the altitude sickness you just mentioned?"

Li Wangyou said with a smile: "Uncle Cheng, I'm afraid you don't know that the distribution of oxygen in this air is also different. The higher the altitude, the thinner the oxygen, and even at extremely high altitudes, we wait for the mortal body The fetus can't breathe at all, and it can kill you in a moment."

"The Qinghai-Tibet Plateau, in addition to the extremely high terrain, the biggest problem is that the oxygen is very thin. If ordinary people enter the plateau, they will experience symptoms such as headache, fatigue, palpitations, shortness of breath, and difficulty breathing due to the thin oxygen. Or even lose their lives.”
