After returning to Jinling, before he could chat with the three ladies, he was immediately summoned into the palace by Zhu Yuanzhang.

"I'm angry with us, these ministers who pick the door are even darker than those landlords and old money, we are saving money now, there is no money to build an academy of sciences, and if we want to borrow some money from them, we are all crying poor, they go to the yard to play on weekdays, why is no one shouting poor?"

Listening to his nagging and complaining for a long time, Lu Ning always listened with a smile and did not interrupt, and waited for him to finish before speaking.

"It's easy to get started and it's hard to shoot, this is human nature, and it can't be changed naturally, if you want to take it out, you have to fight with them."

Zhu Yuanzhang was still a little indignant and said.

"This is the same as what you talked about when you told us the day, the emperor of the foreign country, these guys want to watch us die, and if you really respond to what the emperor said, all the ministers can be killed, do you really think we can't use knives?"

It turned out that Lu Ning had the intention of changing some misunderstandings in the history of the Ming Dynasty, so he changed the appearance of what happened in later generations as an overseas anecdote, and told Zhu Yuanzhang a lot.

For example, in this dynasty, he replaced the Ming Dynasty with overseas countries.

But the era name of the emperor in later generations has not changed, and the story of the emperor and the minister who borrowed money and couldn't borrow the last and had no choice but to hang himself is deeply engraved in Zhu Yuanzhang's heart.

He tasted the sweetness of science, and he wanted to follow Lu Ning's suggestion to become the Daming Academy of Sciences, but now it is disaster relief and support to go to sea, and he really has no money in his hands.

I just want to borrow a little from the ministers, who knows that it is difficult to ask for someone, even the emperor is no exception.

After all, you are not taxing but borrowing friendship, and it is a favor to lend you a favor, and it is your duty not to lend you, and the royal sword is fast, and you can't kill the innocent.

Therefore, no matter how depressed Zhu Yuanzhang was, he wanted to find some reason to click a few whole points of money to support this Daming Academy of Sciences.

He knows that there are very few officials like Liu Bowen who have clean sleeves, and as long as they investigate corruption, they will definitely be accurate.

Lu Ning smiled and said.

"My father wants to clean up the court, this truth is true, the entire Ming Dynasty is still a clean official, there are few corrupt officials, even if you check it once, how long can this money be spent? In the future, where will the money come from to build a science academy to cultivate talents? ”

Zhu Yuanzhang laughed and asked.

"I know that your child has a lot of ideas, and he still has to do to rectify the dynasty, you say, where else can I make money?"

In fact, the Ming Dynasty also has the difficulties of the Ming Dynasty, the world needs to recuperate at the beginning, and it cannot increase taxes from the people.

Heroes who are fighting outside need to be given certain benefits, but they cannot be deprived of their treatment.

Most of the additional military expenditures of the Ming Dynasty now come from the rouge tax revenues in various cities.

Although this kind of tax is a bit embarrassing, it is an unavoidable topic in Daming.

The problem is that even if there is a windfall income here, it is still a drop in the bucket for the Daming science and technology business that is waiting to be built.

It was precisely because of this helplessness that Zhu Yuanzhang came up with a way to borrow money from the gentry.

Lu Ning smiled and said.

"Erchen, the Daming Bank has been established, but unfortunately there are very few people who deposit money here, Erchen must also think of a way, let these people obediently come to my bank to deposit money, as long as the money is deposited in the bank, you can provide some loans to the imperial court at any time, and when we get the benefits of sailing, we are filling the deficit of this item, isn't this game of chess a revitalization?"

Zhu Yuanzhang thought about it, this is the truth.

"And what are you going to do?"

"When Erchen recovered the Zhenhai Islands, he also got the rare treasures collected by those pirates, and we can launch a prize sale."

Zhu Yuanzhang was confused and asked.

"What's a prize sale?"

"We can make some lottery tickets, which are divided into the first prize of the grand prize, the second prize, the third prize and the consolation prize, as well as a number of empty tickets, each lottery ticket, priced at one or two silver, and you can redeem it on the spot if you catch a few prizes."

So, Lu Ning told Zhu Yuanzhang in detail about the routine of prize sales, and only explained that his lips were about to dry, and Zhu Yuanzhang understood the truth.

But he was very worried, he said.

"How tall is a coral tree, you say? The consolation prize is a towel, and there are a huge number of empty coupons, isn't this cheap enough to draw the grand prize, and it hurts those who get the empty coupons? What if these people are poor people? ”

Lu Ning smiled and said.

"Father, what we sell is never a lottery ticket, but a chance to win the lottery, as for whether or not they can win the lottery, it depends on their luck, they can afford to consume these lottery tickets, one or two silver does not matter to them, as for those people, one or two silver may be their income for four or five months, naturally they will not risk coming here to consume, so you don't have to worry about this problem, the number of lottery tickets determines the size of our profit this time."

Zhu Yuanzhang thought about it, and decided to ask Lu Ning to do it in Jinling first, and if this prize sale was successful, it would be promoted to fifteen political departments across the country.

Lu Ning, who returned home, immediately gathered the three ladies and asked them to buy the corresponding paper and make all the lottery tickets.

These ladies all have some talent for business, and Lan Xiaoya is proficient in statistics, so she immediately calculated that the first prize of the special prize, the second prize and the third prize, as well as the ratio of consolation prizes and empty papers.

In less than three days, all these tickets were made.

Lu Ning took the people of his domestic products department to open a prize sales activity in front of the Confucius Temple.

After a while, one of his subordinates reported.

"Lord Wang, we are ready for this scene, but no one cares, what do you think?"
