Just when Zhu Yuanzhang was puzzled, Zhu Biao on the side also asked: "Hu Aiqing, I don't know what this is, why have you never seen it?" ”

It's no wonder that Zhu Biao asked.

As the prince of the Ming Dynasty, he has eaten a lot of delicacies from the mountains and seas.

Whatever flies in the sky and runs on the ground, as long as it can be eaten, it will be offered by the courtiers below.

Although Zhu Biao is not such a person with a heavy appetite, but in order to get by on face, Zhu Biao has also eaten a lot of delicious food.

And not only the food of the Central Plains, Zhu Biao has also eaten a lot of Fanbang food.

After all, the Ming Dynasty is now the leading overlord of the Central Plains, and the small countries around it will also send a lot of specialties from other countries in order to obtain the protection of the Ming Dynasty.

But Rao is Zhu Biao is well-informed, and he has never seen such a strange thing.

Facing the doubts on the faces of Zhu Yuanzhang and Zhu Biao, Hu Changan smiled slightly and said: "This yellow and clear columnar object is called corn, which is a miscellaneous grain, just like millet. ”

"And that round, granular object is called a peanut, and it's a nut that you can eat by peeling off the shell."

"The food, like the potatoes I offered earlier, comes from the vast sea."

Maritime?

And potatoes from the same place?

Zhu Yuanzhang couldn't help but lift his spirit.

Although Zhu Yuanzhang can not care about the appetite, Zhu Yuanzhang can't not care about the stomachs of the people.

If there are a few more high-yield crops like potatoes, the comprehensive national strength of the Ming Dynasty will definitely be able to reach a higher level!

You must know that high-yield crops can not only fill the stomachs of the people, but also liberate the productivity of the people!

Suppose the country has a total of one hundred civilians.

If the crop yield is insufficient, then in order to fill the bellies of these 100 people, 90 of them must carry hoes and become farmers.

As a result, only ten people can do other jobs.

All the artisan soldiers and the like can only be drawn from these ten people.

So it's very likely that only one of these ten people will be selected to join the army.

If only one person wants to defend 99 people, the difficulty in this can be imagined.

However, if the yield of crops is high, then to fill the stomachs of these 100 people, perhaps only 20 people are enough to be farmers!

The remaining eighty people will be able to do all sorts of other jobs.

Among these 80 people, the state can even directly send 20 people to join the army!

In this way, the comprehensive national strength of the Ming Dynasty can be significantly improved.

At least in the area of national defense, Daming's military strength will definitely go to the next level!

And if there are high-yield crops, then the population will have a high probability of choosing to have more children.

After all, in ancient times, children were all resources!

As long as you add a pair of chopsticks, you can have one more strong labor force in the family.

People with a little brain, this kind of arithmetic will be done.

Therefore, within the scope of affordability, ordinary people will choose to have more children.

If high-yielding crops are promoted, the average civilian household can afford to raise more children.

As a result, they will also choose to have more children.

In this way, the number of people in the Ming Dynasty will increase!

With more people, the comprehensive national strength of the Ming Dynasty will definitely go to a higher level!

Zhu Yuanzhang couldn't help but breathe shortly.

As a visionary emperor, he could see the opportunities in it.

Zhu Yuanzhang hurriedly asked Hu Changan: "Hu Aiqing, I don't know what kind of sea you are talking about?" ”

"Are there more high-yielding crops at sea?"

"Isn't this corn and peanuts also like the potatoes, with extremely high yields?"

However, Hu Changan poured a small basin of cold water on Zhu Yuanzhang this time: "Your Majesty, although the yield of corn and peanuts is not low, they can't be as full as potatoes." ”

"In other words, this corn and peanuts can only be used as snacks, not as the staple food of the Ming people."

"Potatoes, which can be used as a staple food and have a high yield, are indeed not too much."

Zhu Yuanzhang also sighed slightly after hearing this.

Sure enough, he couldn't imagine that something good would always happen.

There is such an artifact as potatoes, and it is already the luck of Daming.

However, Hu Changan affirmed Zhu Yuanzhang's conjecture: "Your Majesty, on the other side of the sea, there is a new continent. ”

"There are many crops in the New World that are different from those of the Central Plains, and there are also gold and silver minerals."

"If Your Majesty can organize an expedition, there will definitely be a great discovery!"

Taking this opportunity, Hu Changan is ready to plant a seed of navigation in Zhu Yuanzhang's heart.

Now is the best time for China to sail.

After all, now, Daming's shipbuilding technology is still unique in the world.

According to legend, the treasure ship that Zheng He rode in the Ming Dynasty could reach 151 meters in length and 60 meters in width, which was enough to accommodate thousands of people.

The length of the ship that Columbus rode in the same period was only 35 meters, which was 116 meters shorter than Zheng He's treasure ship.

Moreover, the displacement of Columbus's ship was 100 times weaker than Zheng He's treasure ship!

Today's Ming Dynasty, shipbuilding technology is hundreds of years ahead of Europa!

It can be said that at the technical level of the voyage, Daming is absolutely no problem.

It is a pity that due to the policy of sea ban, Daming's shipbuilding technology stopped and was gradually overtaken by the Europa curve.

So now, with the world's unique shipbuilding technology, Daming will definitely be able to achieve far more than Columbus!

Zhu Yuanzhang was also silent when he heard it.

This idea put forward by Hu Changan is exactly contrary to the maritime ban policy he proposed.

Originally, Zhu Yuanzhang didn't understand the benefits that the sea could bring.

In Zhu Yuanzhang's eyes, the sea is just a larger lake, except for bringing some catches, there is nothing else.

Therefore, when Chen Youliang's remnants combined with the Japanese invaders repeatedly violated the maritime border of the Ming Dynasty, Zhu Yuanzhang did not hesitate to implement the maritime ban policy.

In Zhu Yuanzhang's view, as long as you eat less fish, you can avoid the bloodshed caused by the massacre of the people by the Japanese invaders, which is very cost-effective.

But now, Zhu Yuanzhang hesitated.

If Hu Changan is right, then there are inexhaustible treasures on the other side of the sea.

If this is the case, then the sea ban will definitely do more harm than good!

However, when Zhu Yuanzhang hesitated, the corn was already roasted.

Seeing this, Hu Changan hurriedly took out the charcoal in the stove, picked up two corns with a clean handkerchief, and gave one to Zhu Yuanzhang and Zhu Biao.

Taking over the corn in his hand, Zhu Yuanzhang also temporarily gave up his heavy thinking.

Such a major event cannot be decided overnight.

For now, let's take a look at Hu Changan's craftsmanship first.

However, in Zhu Yuanzhang's heart, a seed of navigation was quietly planted.
