"Lord Xiao said this, I naturally agree, can enlighten the wisdom of these people, of course there is nothing to oppose in the future, but there are some things, we really can't give them." Zhang Nan said.

Others don't know, Zhang Nan is very clear, when Zhenguan was 14 years old, Songtsen Gampo asked the Tang Dynasty for marriage, and Princess Wencheng entered Tibet.

In addition to the treasures of the Buddha statue, treasures, and gold and jade bookcases, more importantly, there are 300 kinds of divination classics, 60 kinds of construction and engineering works, 100 kinds of treatment prescriptions, 4 kinds of medical treatises, 5 kinds of diagnostic methods, and 6 kinds of medical devices. It also carries a variety of grains and turnip seeds, among other things.

This dowry can be said to have benefited Tubo a lot, and the most important thing that Princess Wencheng brought was the advanced Central Plains culture at that time. This directly promoted the great development of Tubo, and also cultivated a difficult opponent for the later Tang Dynasty.

"Oh? Qingquan, tell me, what can't we give them? Li Er sat on the dragon chair and asked.

"This is simple, Your Majesty, will you teach these people how to make kamikaze crossbows and thunderbolts?" Zhang Nan asked rhetorically.

"Of course not, how could I teach them such a secret thing?" Li Erdao.

"Of course, in addition to these weapons, the construction and engineering works of our Ministry of Industry, and the medical research of our Datang Medical College, none of these can be given to them." Zhang Nan said with a straight face.

"Master Zhang, you said that these weapons are not given to the Japanese people, this old man can still understand, but this construction and engineering work and medical book or something, why can't you give it?" Xiao Yu's head still doesn't understand, this is clearly a good time to show the national strength of the Tang Dynasty and make the country grateful to Dade.

"Then I'll ask Lord Xiao, we have handed over this work of construction and craftsmanship to the Japanese people, and the walls they have built are as strong as ours, but it will not cost us a lot more when we fight them. We have given them this medical skill, so when they go to war with us, will they not recover from their injuries as quickly as we do, so why should we suffer? Zhang Nan said.

"Lord Zhang, you obviously want to attack the Japanese Kingdom." Xiao Yu blew his beard and glared.

Xiao Yu has been an official all his life, and he has never seen such a belligerent Wenchen, of course, but Xiao Yu thinks that Zhang Nan is a Wenchen.

"Lord Xiao, don't you want to tell me that the warmongers will die?" Zhang Nan said with a playful face.

"It turns out that Master Zhang, you understand this truth, the old man still thinks you don't understand."

"I naturally understand this truth, I just want to ask, if we don't beat them, how can we ensure that they don't beat us?" Zhang Nan sneered.

"This, in a corner of the Japanese country, also has the ambition of a wolf son who dares to touch my Tang Dynasty?" Xiao Yu looked puzzled. Even Li Er was puzzled, where the fart of the country was bigger, he could fight the idea of the Tang Dynasty, isn't this a man sitting on a stone with his bare ass and hitting a stone with an egg?

"Qingquan, I also think that you are too worried, I expect that the small Wa Kingdom does not have such great courage." Li Er said.

"None? Okay, the minister will analyze the emperor and your colleagues today why this Japanese kingdom will invade us one day in the future. After Zhang Nan finished speaking, he looked around and found that everyone looked like they were listening, so Zhang Nan continued.

"Except for the abundance of fishery products, there are basically no decent large-scale minerals. We in Datang have almost all the resources to start industrial production. Therefore, Japan urgently needs large-scale mining areas close to the mainland. Of course, the adults I am talking about in this industrial age may not be very clear, and when the Ministry of Heavenly Engineering successfully applies steam equipment to production, you will understand. Zhang Nan said.

"Qingquan, the steam equipment you mentioned is the big ship that can float across the ocean." Li Er still hasn't forgotten his plan to go out in search of high-yield food.

"That's right, it's just the tip of the iceberg." Zhang Nan nodded and continued: "Also, their products are very low, but their ambitions are huge, a country with ambitions but not enough capital can only do aggression, and constant aggression is their goal." ”

After Li Er heard this, he frowned and said, "Qingquan, why do you know this country so well, is it difficult for you to go there?" ”

When the ministers heard this, they all looked curious. So Zhang Nan decided that if he wanted to cheat, he had to cheat to the end, although Zhang Nan had never traveled to Japan in later generations, but this did not affect Zhang Nan's understanding of this country at all.

"The minister is fortunate to follow the minister's master to wander the world, of course, this Japanese minister has also been there." Zhang Nan said.

"Oh? Qingquan, you have actually been to the Wa Kingdom, so you can tell me what kind of country this Wa Kingdom is. Li Er asked with interest.

"Let's not talk about what kind of country this Japanese country is, but do you know what this Japanese king claims to be?" Zhang Nan asked.

"What is it?"

"The Emperor." Zhang Nan's casual two words caused the courtiers in the court to gasp, even if it was Li Er, it was just a self-proclaimed Son of Heaven, and this small country dared to call itself the emperor.

How did Zhang Nan know the name of the Japanese emperor, and the earliest written record was the "Asuka Jo Gohara Order" promulgated by Japan in 689. And China began to call the head of Japan emperor around the end of the Qing Dynasty, during the Tongzhi period.

Anyway, the emperor of Japan has always been called the emperor, and as for when it started, Zhang Nan doesn't know.

However, this is also a mistake, because after listening to Zhang Nan's words, Li Er's face became very ugly. The Emperor of China, the first of the three ancient emperors (the Emperor, the Emperor of the Earth, and the Emperor of Thailand). The emperor of the Japanese is a descendant of Amaterasu, the god of creation in Japanese mythology, and is also the supreme leader of Shinto and the national symbol of Japan. It's not a thing at all.

But this wonderful misunderstanding successfully annoyed Li Er.

Li Er thought that he had not reached the standard of the emperor, and this small Wa kingdom actually dared to call himself the emperor, which made Li Er, a person who had not been called "Tian Khan" for a long time, suddenly feel that he was despised.

"It's really presumptuous." Li Er said with a gloomy face.

"And Your Majesty, do you really think that those Japanese people are humbly asking me for the cultural knowledge of the Tang Dynasty? Of course, this must be part of it, and if I want to see, what this Japanese people want more is these things about military schools and kamikaze crossbows. Zhang Nan sneered.

"What, how could these Japanese people know these things, this is impossible." Li Er's face was shocked, not only Li Er, but also the courtiers were very unconvinced.
