In this way, Lu Ning stayed in the Black Tooth Country for half a year in a daze.

Although he was a little unaccustomed to the tropical food here, he gradually got used to it.

Besides, Zhu Xiongying always arranged for someone to make an airdrop for him, and the airdropped materials were naturally some daily necessities and various foods.

Therefore, although Lu Ning is a little homesick here, he is still very comfortable.

In between, he flew back once.

However, it was this time that he seemed to be a little lacking in nutrition, after all, the wife at home has a lot of them every day, and he has to deal with it before he can go on a business trip again.

He was thinking that if the little blue film, which was developed at the beginning but was not put on the market on a large scale, it would definitely be a necessary gas station for men.

If it can be sold in Daming, it must also be a huge market.

Not only can you make a lot of money for the Ming household, but you can also make a wave of profits for yourself, why not do this kind of thing?

After waiting for the matter of black teeth to come to an end, they returned to Daming and promoted the little blue film they invented with Zhu Yuanzhang.

In the past six months, the gold and minerals from the Black Tooth Country have been continuously transported to Daming, so that Daming has a strong gold reserve.

At this time, Zhu Yuanzhang was reviewing the folds in the Qinzheng Palace, and suddenly Liang Qingbiao, the head of the household department, walked in, and it could be seen that his expression was very excited.

After the courtesy of the monarch and the minister, Liang Qingbiao took out a report, and then said to Zhu Yuanzhang.

"Your Majesty, this is the data just reported by Daming Bank, our household department has already verified, and now the bank's gold reserves have reached a very amazing level, it is already very unbelievable, Your Majesty!"

Zhu Yuanzhang looked at the important minister of the court in front of him, and thought to himself, has this guy seen money? Why is there such a fuss.

So, he asked with a smile.

"Liang Aiqing, why are you so excited? Is there anything that can't be said slowly, no matter how much money there is in Daming Bank, can it still have more transfer department? How much gold they store, just tell me! ”

Liang Qingbiao nodded, and then told Zhu Yuanzhang very solemnly.

"Your Majesty, now the gold deposited in the Daming Bank has exceeded 50 million taels, which is an astronomical amount, and for this alone, His Royal Highness the King of Changning has made great contributions to Sheji, and is the absolute minister of the imperial court."

Zhu Yuanzhang was taking a sip of tea, and after listening to this number, he almost choked.

When has the household department of the Ming Dynasty never been so rich, 50 million taels of gold reserves, which is equivalent to 50,000 taels of silver.

For this alone, Lu Ning is indispensable, he is simply the white jade pillar of the imperial court, and the purple gold beam of the sea.

So, Zhu Yuanzhang sent a telegram to Lu Ning, asking him to rush back as soon as possible.

Lu Ning rushed back as soon as possible by plane, and he first presented a big gift to Zhu Yuanzhang.

This is a blood-piercing Amitabha Sutra, which is used to pray for blessings.

This is a gift from Chief Bruce to the Ming Emperor, and it was carefully made by all the tribal leaders of the Black Tooth Country.

Zhu Yuanzhang put the gift away, and then said to Lu Ning.

"These tribal leaders of the Black Tooth Country have such filial piety, we will reward them well in the future, but this is also your credit."

Lu Ning shook his head indifferently, and then said to Zhu Yuanzhang.

"Father, what the sons want to tell you is not these, now those heroes of the Ming Dynasty have a home, and they have also set the corresponding rules for them, they will come to pay homage to you every three years, and the Ming fleet will gather at any time if necessary, and continue to move forward."

Zhu Yuanzhang nodded, and then told Lu Ning very solemnly.

"With you doing things, we don't have anything to worry about, you are a good boy given to us by God, this time we can get so much gold from the Black Tooth Country, and then Daming Bank has enough reserves, do you have any plans next?"

Lu Ning smiled, and then replied to Zhu Yuanzhang.

"This is exactly what Erchen wants to ask you, now that we have enough gold, it is better to change the silver standard to the gold standard, so that the wealth is more sufficient."

Zhu Yuanzhang nodded in agreement, and then asked Lu Ning if he had any other ideas.

Lu Ning thought carefully for a moment before speaking.

"Erchen believes that now with so many gold reserves, treasure money is naturally the world's largest hard currency, but also more valuable, I think the market only needs to issue paper money in the future, heavy metals are under state control, not allowed to circulate in the market."

Although Zhu Yuanzhang didn't understand Lu Ning's intentions in arranging this, he still agreed and asked Lu Ning to preside over this matter.

"We have already said that you are in charge of this matter of Daming Bank, and you are also the absolute hero of this reserve of so much gold, we must agree to your invitation!"

Now that the business is finished, Lu Ning said to Zhu Yuanzhang.

"Just let the officials below arrange this kind of thing, it will be tiring to death if you have to bow to your relatives, and the sons and daughters also want to let their father rest well, and they can't be too tired."

Zhu Yuanzhang understood in his heart that this statement was naturally Lu Ning's filial piety, and he nodded and said.

"Don't worry, now Xiongying is also making great progress, and your eldest brother's health is getting better and better, so we should enjoy a few days of happiness."
