Of course, Datang can also develop the whaling industry on its own.

However, the location of the Ryukyu Kingdom is more suitable for the development of this industry.

As for the people of the Tang Dynasty, Qin Fan has other plans.

Rather than having people venture out to sea, it is better to teach them how to make practical objects out of the whale's parts.

In this way, the whales caught by the Ryukyu Kingdom could be sold to the people of the Tang Dynasty.

After the processing of the people of the Tang Dynasty.

The value of whale products can be multiplied several times.

This is the riskiest link for the Ryukyu Kingdom to do.

The big head is earned by the people of the Tang Dynasty.

At the same time, Ryukyu will also be grateful to Dade.

Doesn't it smell?

Therefore, Qin Fan only needed to throw the drawing of the whaling ship to him before the Ryukyu envoy Moser left, and teach him the method of catching kun.

The other party must be grateful to Dade for sending a large sum of silver to Datang!

"But counting on the silver from the trade of the Ryukyu Kingdom is not a long-term solution after all." Qin Fan said.

You can't just catch a sheep all the time, right? Sooner or later, the Ryukyu Kingdom will have to be bald.

Hearing this, the eldest grandson Wuji showed an exaggerated expression:

"Isn't it! You can't help it! Tut-tut!"

Qin Fan said with an indifferent face, "It's useless to stir up the generals!"

The eldest grandson Wuji whispered, "Cut, have you been recognized?"

Qin Fan made a straight face: "I can hear it!"

"What if you can hear me?"

Li Shimin looked at the two bickering and couldn't help laughing.

He hurriedly said, "Then Brother Qin, is there any other way to get the money?"

Qin Fan smiled and said, "There are many ways to get money, it depends on whether you want to come quickly or for a long time."

"Is it high risk and high reward, or is it a slow plan?"

Eldest Sun Wuji's eyes lit up: "Is there that kind of money, which comes quickly and abundantly, and the risk is small, and it can be maintained for a long time?"

Qin Fan smiled: "Of course there is!"

Eldest Sun Wuji's eyes lit up: "Tell me quickly, what should I do?"

Qin Fan pointed to the wine on the table.

The eldest grandson Wuji was stunned for a moment and asked, "You mean selling wine?" Can you really make that much money from this wine seller?"

Qin Fan's face was full of black lines: "I'm asking you to drink a few more, get drunk, you have everything in your dreams!"

The eldest grandson Wuji was angry: "You!"

"What you, you! Talking in the middle of the day in the middle of the day? If there is such a way, where can we wait for you and me to do it?" Qin Fan glared and retorted.

The eldest grandson is unscrupulous, but his momentum has not weakened at all.

Li Shimin on the side conciliated: "Okay, okay! Brother Qin, don't worry about him. Let's talk about it!"

"It's better to solve the problem of funding for dam construction! The shorter the time, the better."

Qin Fan smiled: "Then issue treasury bonds!"

"National debt?" Li Shimin was slightly stunned.

Today, this Qin brother said a lot of things that he didn't understand.

"In short, the national debt is to borrow silver from the people of the Tang Dynasty or people from other countries in the name of the imperial court, and repay the principal and interest when due."

"Borrowing silver? Will they borrow it?" Li Shimin wondered.

"Why not? How can you not borrow with enough interest?"

"You know, the national debt is guaranteed by the reputation of the entire Datang!"

"Unless there is no tax to collect, it will definitely be able to repay the national debt smoothly, or with interest!"

"Isn't it more cost-effective to use the silver to buy government bonds than to bury it in the ground and store it?"

"As long as the imperial court is willing to issue treasury bonds, don't worry about the clan not borrowing silver!"

Qin Fan's firm way.

However, Li Shimin hesitated again, and really borrowed silver in the name of the imperial court, which involved too much.

One can't get it back

If you don't have enough money, it may lead to the collapse of the dynasty.

"Then what if I wait until the deadline is up, and I can't afford to pay back the silver?"

"How can you not afford to pay it back?"

Qin Fan pursed his lips.

"It's not a usury! As long as there is a little bit of profit, the other party will definitely be willing to lend it."

"And the court got the money, and it was used to build dams and so on."

"You think, even though it takes a lot of money to build a dam."

"But once the dam is repaired, there will be no need to spend money on Huainan for disaster relief in the coming year."

"Not only do we not need to provide disaster relief, but the people can also have a good harvest, so there is another tax payment."

"This in and out, it's a lot of income."

"And with the start-up capital borrowed from the soldiers, the imperial court can do business on its own, and the place where it can make money is gone!"

Hearing this, Li Mengwei shook his head and said, "The imperial court does business? How can this be done? Isn't this a competition with the people?"

Qin Fan pursed his lips: "It's okay to compete with the people for profit, but you can compete with the family for profit!"

"What's more, there are many other businesses that have not been developed, and the imperial court can develop in these directions."

"For example, the pig powerhouse! The imperial court could have set up pig farms and sell the pork when it was produced."

"Castrated pigs have a high meat yield and no fishy smell, so they are not necessarily inferior to mutton."

"Or spice farming, isn't this chili a good business?"

Qin Fan gave examples one by one, and analyzed the prospects of various industries, and Li Shimin was excited when he heard it.

According to Qin Fan, the treasury of the Tang Dynasty is full, just around the corner!

"Then I'll go back and let my friend who is a senior official give advice to His Majesty on the issuance of treasury bonds?"

Li Shimin couldn't wait.

"Wait!" Qin Fan opened his mouth to stop Li Er, who was in a fanatical state.

"Before the issuance of treasury bonds, we must first set up a money bank belonging to the imperial court, and everything will be handled by the bank."

Hearing this, Li Shimin was puzzled: "Why is this?"

Qin Fan raised his forehead: "Have you forgotten the virtues of those officials and gentry?"

"Even if it is the disaster relief money, they have to use their hands and feet, not to mention the money collected from the national debt of the imperial court!"

"Therefore, we cannot go through the original system of the gentry, but have to establish another system, and the money bank was born for this."

"Not only that, but we also need to appoint trustworthy people to strengthen supervision. Thou shalt not make the man of the bank to steal for himself. All transactions need to be accounted for!"

Qin Fan explained the points that needed to be paid attention to one by one, while Li Shimin nodded frequently, his eyes shining.

At that moment, a voice came: "What a fragrance! Is this too late?"

Looking at the leftovers on the table, Sun Simiao said with regret on his face.

Qianqian smiled and said, "Doctor Sun, don't be disappointed, the kitchen has a bowl for you!"

"Good! Okay!" Sun Simiao was overjoyed.

This is, Qin Fan opened his mouth and said, "Old Mr. Sun, you came just in time, Boss Li has a friend here, and he needs you to give La a knife!"

As he spoke, Qin Fan turned his head and said, "Chang Meng! Chang Meng? Your ass has been saved!"

"Strange, what about people? I remember he was just here!"

Looking around left and right, where can Qin Fan still see Li Mengwei's figure!
