Every time Zhang Nan was left by Li Er in the early dynasty, he had the illusion of being left in the classroom by the teacher when he was in school, of course, Zhang Nan was used to it, as long as he said something in the early dynasty, it would be strange not to stay and be asked by Li Er.

This time, Li Er still chose the place to meet in the imperial study, and when Zhang Nan stood still in the imperial study, Li Er said straight to the point: "Qingquan, what you said is true?" ”

"What the minister said is naturally true, and there will never be half a lie." Zhang Nan said.

"You said that we will go to war with the Wa Kingdom within thirty years, is that true?" Li Er continued to ask.

"I use the head guarantee of the item, there will definitely be a war, and this battle will definitely be fought, and the Wa Kingdom will see who is the boss clearly." Zhang Nan said with a smile, in fact, what Zhang Nan said was not wrong, the Battle of the Baicun River was a direct contest between Japan and the Tang Dynasty, which established the central position of the Tang Dynasty in East Asia.

In the face of the powerful Tang Empire, the bitter lessons of the war forced Emperor Tenchi to re-examine his foreign policy. As a result, Japan revised its foreign policy in a timely manner, restored diplomatic relations with the Tang Dynasty, and began to actively select and send Tang envoys to study the politics, economy, and culture of the Tang Dynasty in an all-round way.

It also indirectly contributed to Japan's rapid development.

"I don't want your head on the neck, and I don't want to see this war in thirty years' time, so you can talk about it." Li Erdao.

"Then the emperor, you will fight it, anyway, you will fight, no one can say anything, and you can solve the hidden dangers of Datang in advance, why not?" Zhang Nan looked like a matter of course, in Zhang Nan's opinion, attacking the Wa State is not the same as attacking the Turks, and the Tang Dynasty has to find an excuse to fight the Turks, so that he can look justified, but the Wa State, Zhang Nan doesn't think so, just fight, I should beat you.

"Having said that, it's just that the real estate of this Japanese country is scarce and the population is sparse, and we are mobilizing our troops to fight them, which is completely thankless, and this battle is not enough for us to start a war." Li Er is also the leader of the word now.

As Li Er said, now the Wa Kingdom is really the master who doesn't have enough oil money to beat him, and if he runs away, the slaves can't catch much, and the real estate can't get much, it's a completely loss-making business.

Although the Tang Dynasty says that it has money, it has not yet had the money to fight at any cost, which is inconsistent with the theory of purpose war put forward by Zhang Nan.

"Your Majesty, don't worry, wait, in fact, I really don't know much about this Japanese real estate." After Zhang Nan finished speaking, he searched carefully in the system, this check didn't matter, it really made Zhang Nan find out something.

Although Japan is an island country and relies heavily on imports for all kinds of minerals, this does not mean that Japan really has nothing at all.

Zhang Nan quickly set his sights on the silver mines in Japan.

Iwami Silver Mine, located in Shimane Prefecture in the Sanin region of Japan. Discovered in the 16th century, the deposit was one of the world's most representative silver deposits in the seventeenth and eighteenth centuries. To the Iwami Silver Mine closed in the 20s of the last century. Iwami Ginzan has been mined for more than 400 years since 1526 and was the largest silver mine in Japan from the late Warring States period to the early Edo period. In the 17th century, silver production here accounted for one-third of the world's total silver production.

The development of Iwami Ginzan coincided with the period of commercial development in Japan's economic history, so the silver smelted here was not only circulated in Japan as currency, but also supported trade between Japan and Portuguese, the Dutch East India Company, and Chinese merchants. In Japan, "Iwami Ginzan" is also highly valued, showing the importance of its existence.

Zhang Nan didn't know how much silver reserves this Iwami Silver Mine had, but if it could be mined for four hundred years, it would definitely be a lot of money.

So Zhang Nan decided to let Li Er be a warmonger, defeat the Japanese state, and then mine silver mines, which can fully pay for the war launched by the Tang Dynasty.

"Your Majesty, the minister wants to tell the truth, the minister just said in the court that the real estate of the Wa Kingdom is scarce, and there is still a bit of a problem." Zhang Nan said truthfully.

"Oh? What's the problem. Li Er asked.

"Although the Japanese country has scarce real estate, it does not mean that he does not have real estate, such as silver mines, and on the small island where the Japanese country stays, there is a silver mine that can be mined for a hundred years." Zhang Nan said.

After Li Er heard this, his eyes straightened, and he asked excitedly, "Qingquan, what you said is true?" ”

"This, Your Majesty, when did the minister deceive you." Zhang Nan smiled bitterly.

"There is such a silver mine, how can I not take it, I want to go immediately, mine it one day earlier, and my Datang will be able to get rich one day earlier." Li Er said with emotion, what Li Er said was as simple as going to his own backyard to get an egg, and he didn't take the country into consideration at all.

However, Li Er really doesn't have to think about it, no matter whether Wu Guotong agrees or not, this Iwami Silver Mine has already been remembered by Li Er. There is only one way for those who hinder Li Er's fortune, and that is death.

"Your Majesty, if you want to mine silver mines, you have to wait until the steam engine is applied to the Tang Dynasty, at that time, the mining speed is not comparable to now, now give those Japanese people a few more days, then we will drive a steam boat directly to get it, how good, by the way, you can also go there for a trip, although it is poor over there, and it is a barbarian country, but the scenery is still good." Zhang Nan said with a smile.

"Well, then I'll wait, what happened to your Heavenly Work Department, I'll wait to see." Li Erdao.

"The Ministry of Heavenly Work will be completed in about a month, after all, the minister has repaired a lot of confidential things in it, but the private club is almost established, and in two days, the emperor will be able to take the queen to experience a super high-end life, and the minister guarantees that it is really an unprecedented experience." Zhang Nan said.

Zhang Nan's words are true, Zhang Nan's private club is full of modern decoration products that have been replaced in the system, and even the slots of the wiring are reserved for Zhang Nan, just waiting for the arrival of the electricity era, for Zhang Nan, it took others a hundred years or more to build epoch-making products, Zhang Nan only needs more than ten years to complete the safe transition.

That's the benefit of the traverser.

"Well, I know, when the time comes, you remember to send me the membership card to the palace, by the way, I still have something to ask you." Li Erdao.

"Your Majesty, you say."

"How many years can my Datang go?" After Li Er finished speaking, Zhang Nan raised his head to look at Li Er and found that Li Er was looking at him, so the two began to stare wide-eyed. Thank you book friends for the reminder about Japan's mineral issues.
