Every time Zhang Nan was kept by Li Er in the morning court, he had the illusion that he was left by the teacher when he was in school. Of course, Zhang Nan had long been used to it. It would be strange that Li Er asked about anything he said in the morning court and did not stay.

This time, Li Er still chose the meeting place in the imperial study room. When Zhang Nan stood in the imperial study room, Li Er said straight to the point: "Qingquan, what you said is true?"

"What I said is naturally true, and there will never be any false words." Zhang Nan said.

"What you said we will go to war with Japan within thirty years, which is true?" Li Er continued to ask.

"I guarantee that I will definitely start a war, and this battle will definitely fight Japan. I will see who the boss is." Zhang Nan said with a smile. In fact, what Zhang Nan said is right. The Battle of Baicun River and the Navy was a direct contest between Japan and the Tang Dynasty, which established the central position of the Tang Dynasty in East Asia.

Faced with the powerful Tang Empire, the painful lessons of the war prompted Emperor Tianzhi to re-examine his foreign policy. Therefore, Japan promptly revised its foreign policy, restored its national relations with the Tang Dynasty, and began to actively select and send Tang envoys to learn the politics, economy and culture of the Tang Dynasty in all aspects.

It also indirectly promoted the rapid development of Japan.

"I don't want your head, and I don't want to see this war in thirty years. Just tell me what to do about this matter." Li Erdao.

"Then yourselves, you'll hit it anyway. No one can say anything, and it can solve the hidden dangers of the Tang Dynasty in advance. Why not do it?" Zhang Nan looked as if he was taken for granted. In Zhang Nan's opinion, attacking Japan is different from attacking the Turks. The Tang Dynasty has to find an excuse to fight the Turks so that it seems more legitimate. But in Japan, Zhang Nan doesn't think so. He will hit you. It's natural for me to hit you.

"With that being said, Japan is just a sparse real estate and a sparse population. We mobilize a large number of troops to fight them. It is completely thankless to do our best. This war is not enough for us to start the war." Li Er is now also taking the lead in profit.

As Li Er said, Japan is really a master who doesn’t have enough money to beat him. He mobilized all the troops to go back, and even the slaves could not catch them, and the real estate could not be obtained. It was a total loss-making transaction.

Although the Tang Dynasty is rich now, it is not as rich as it can to fight at any cost, which is inconsistent with the purpose war proposed by Zhang Nan.

"Your Majesty, don't worry, wait. Actually, I really don't know much about this Japanese real estate." After Zhang Nan said that, he searched carefully in the system. It doesn't matter if this search was made, and Zhang Nan really found something.

Although Japan is an island country and relies heavily on imports of various minerals, this does not mean that Japan really has nothing to do.

Zhang Nan quickly focused his attention on the silver mine in Japan.

Ishimi Silver Mine is located in Shimane Prefecture, Sanyin District, Japan. The deposit was discovered in the 16th century and was one of the world's representative silver deposits in the 17th and 18th century. It was the Ishimi Silver Mine that was closed in the 1920s. Ishimi Silver Mine has been mining for more than 400 years since 1526, and it was the largest silver mine in Japan from the late Warring States Period to the early Edo Period. In the 17th century, the silver output here accounted for one-third of the world's total silver output.

The development period of Ishimi Ginshan overlaps with the commercial development period in Japan's economic history. Therefore, the silver smelted and processed here was not only circulated in Japan as a currency, but also supported trade exchanges between Japan and Portugal, Dutch East India Company and Chinese merchants. In Japan, "Ishimi Ginshan" was also highly valued, showing its importance.

Zhang Nan didn't know how much silver reserves this Shijian Silver Mine had, but it could be mined for a full four hundred years, so it must be a big figure.

So Zhang Nan decided to let Li Er be a war dealer, defeat Japan, and then mine silver mines, which could completely pay the money for the Tang Dynasty to launch the war this time.

"Your Majesty, I want to tell the truth. The Japanese real estate in the court just now is rare, and there is still some problem." Zhang Nan said truthfully.

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

"Although Japan has few real estate, it does not mean that it does not have real estate. For example, silver mines. There is a silver mine that can be mined for a hundred years on the small island in Japan." Zhang Nan said.

After hearing this, Li Er's eyes widened and asked with an excited look: "Qingquan, what you said is true?"

"This, Your Majesty, when did you deceive you?" Zhang Nan said with a wry smile.

"With such a silver mine, how can I not take it? I have to go there immediately. I will mine it one day earlier, and I will be rich one day earlier." Li Er sighed. What Li Er said was as simple as going to his backyard to get an egg, and he did not put Japan in consideration at all.

However, Li Er really doesn't have to consider it. Regardless of whether Japan agrees or not, the Shijian Silver Mine has been remembered by Li Er. There is only one way to prevent Li Er from getting rich, 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. The mining speed at that time is not as good as it is now. Now let the Japanese people jump around for a few more days. Then we will drive a steamboat to pick it up. How great is it. By the way, you can also travel there. Although there is poor and a barbarian country, the scenery is still good." Zhang Nan said with a smile.

"Well, then I'll wait a little longer. How is your Tiangong Department going? I'm waiting to see it." Li Er said.

"The Ministry of Heavenly Works was completed in about a month. After all, I have built a lot of confidential things in it, but the private club has been almost established. In two days, you can take the Queen to experience a super high-end life. I promise that it is really an unprecedented experience." Zhang Nan said.

Zhang Nan's words are true. Zhang Nan's private club uses modern decoration products replaced in the system. Even the cable slots are reserved, just waiting for the arrival of the power era. For Zhang Nan, it only takes more than ten years for Zhang Nan to complete the safety over-the-top products that others have used for a hundred years or more to build.

This is the benefit of time travelers.

"Well, I understand. Then you remember to send the membership card to me to the palace. By the way, I have something to ask you." Li Er said.

"Your Majesty, you said."

"How many years can my Tang Dynasty last?" After Li Er said that, Zhang Nan raised his head and looked at Li Er and found that Li Er was looking at him, so the two began to stare at him. Thank you for your reminder about Japan's mineral issues.
