"I naturally agree with this, and I can enlighten the wisdom of these people. Of course, there is nothing to object to, but we really can't give some things." Zhang Nan said.

Others don’t know, but Zhang Nan clearly said that in the 14th year of Zhenguan, Songtsen Gampo proposed to the Tang Dynasty and Princess Wencheng went to Tibet.

Comrade Li Er's dowry was heavy. In addition to the treasures such as Sakyamuni Buddha statues, treasures, and gold and jade bookcases, more importantly, there are 300 divination classics, 60 creative and technical works, 100 prescriptions for curing diseases, 4 medical discussions, 5 diagnostic methods, and 6 medical devices. They also carry various grains and turnip seeds.

This dowry benefited Tubo a lot, and the most important thing 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 be given to them?" Li Er asked while sitting on the dragon throne.

"This is simple. Master, will you teach these people the method of creating the Shenfeng Crossbow and the Sky Thunder?" Zhang Nan asked back.

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

"Of course, except for these weapons, our Ministry of Works' construction and technical works, and our medical research at Datang Medical College, can't be given to them all." Zhang Nan said seriously.

"Mr. Zhang, you said that these weapons are not given to the Japanese. I can still understand them, but why can't I give them to them, such as construction, craftsmanship and medical books?" Xiao Yu still didn't understand. This was clearly a good time to demonstrate the national strength of the Tang Dynasty and make Japan grateful.

"Then I want to ask Lord Xiao. We handed over this construction and technical work to the Japanese. The walls they built were as strong as ours. But wouldn't we have to pay a lot of extra work when we beat them later? We handed over this medical technique to them. When they started a war with us, wouldn't the injuries recover as quickly as we did? Then why should we do it?" Zhang Nan said.

"Mr. Zhang, you obviously want to attack Japan." Xiao Yu said with a glaring look on his beard.

Xiao Yu had never seen such a warlike civil official in his life. Of course, Xiao Yu thought Zhang Nan was a civil official.

"Mr. Xiao wants to tell me that the warriors will die?" Zhang Nan said with a playful look on his face.

"So Lord Zhang, you understand this principle. I thought you didn't."

"I naturally understand this principle. I just want to ask, if we don't hit them, how can we guarantee that they won't hit us?" Zhang Nan sneered.

"This, there are also wolves who dare to touch my Tang Dynasty in a corner of Japan?" Xiao Yu looked puzzled. Even Li Er was puzzled. The bigger the Japanese were, he could have the idea of ​​the Tang Dynasty. Isn't this a man sitting on a stone with his butt naked and hitting the stone with his eggs?

"Qingquan, I also think you are worried too much. I think that the little Japanese country is not as brave as that." Li Er said.

"No? Okay, I will analyze and analyze the emperor and colleagues today why Japan will invade us one day in the future." After Zhang Nan finished speaking, he looked around and found that everyone was looking at the ears of his ears, so Zhang Nan continued.

"In addition to the particularly rich fishing products in Japan, there are basically no decent large minerals. Our Tang Dynasty has almost all the resources to start large-scale industrial production. Therefore, Japan urgently needs large-scale mining areas close to the local area. Of course, you may not be very clear about the industrial era I am talking about now. When the Ministry of Tiangong successfully applies steam equipment to production, you will understand." Zhang Nan said.

"Qingquan, the steam equipment you mentioned is the big ship that can cross the sea." Li Er still did not forget his plan to go out to find high-yield food.

"That's right, this is just the tip of the iceberg that can be applied." Zhang Nan nodded and continued: "Also, their products are very low, but their ambitions are huge. A country with ambition but not enough capital can only do invasion, and continuous invasion is their goal."

After hearing this, Li Er frowned and said, "Qingquan, why do you know this Japan so well? Is it hard for you to have been to?"

After hearing this, the ministers looked curious. So Zhang Nan decided to cheat to the end. Although Zhang Nan had never traveled to Japan in later generations, this did not affect Zhang Nan's understanding of this country at all.

"I am lucky to wander around the world with my master. Of course, this Japanese minister has been there too." Zhang Nan said.

"Oh? Qingquan, you have been to Japan. Then you can tell me what kind of country this Japan is." Li Er asked with interest.

"Let's not talk about what kind of country this Japan is. Do you know what the king of Japan claims to be?" Zhang Nan asked.

“What is it?”

"Emperor." Zhang Nan's casual words caused the ministers in the court to take a breath. Even Li Er just called himself the emperor. This little Japanese dared to call himself the emperor.

Zhang Nan did not know that the earliest written record of the name of the Japanese Emperor was the "Aoi Mihara Order" issued by Japan in 689. China began to call the Japanese head of state the emperor during the Tongzhi period in the late Qing Dynasty.

Anyway, the Japanese emperor has always been called Emperor, so Zhang Nan doesn’t know when it started.

But this is also wrong, because after hearing Zhang Nan's words, Li Er's face became very ugly. The Emperor of China was the head of the three ancient emperors (Emperor, Earth Emperor, and Thai Emperor). The Emperor of the Japanese was the descendant of Amaterasu, the god of creation in Japanese mythology. He was also the supreme leader of Shintoism and a symbol of Japan's country. He was not the same thing at all.

But this wonderful misunderstanding successfully annoyed Li Er.

Li Er thought he had not met the standards of the Emperor. This little Japanese country dared to call himself the Emperor, which made Li Er, a person who had just been called "Tian Khan" for not long, suddenly felt that he was being despised.

"I'm really arrogant." Li Er said with a gloomy face.

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

"What, how could these Japanese people know about these things? This is impossible." Li Er looked shocked. Not only Li Er, but even the courtiers were very disbelief.
