Jeju Island in Goryeo is originally a place where the Mongols raise horses. Because the island is rich in water and grass and flat and fertile, it is very suitable for the growth of horses. After Zhu Di occupied Goryeo, Jeju Island became even more special. The good horses produced on the island are second. The key is that its location is really important. After all, almost all the silver transported from Japan to the Ming Dynasty must pass here.

It is precisely because of this that Zhu Di started building this island many years ago, and the ports on the island also developed very rapidly. Material exchanges between the Ming Dynasty and Japan were generally also transferred here, so Jeju Port has become the largest port in Goryeo.

It is worth mentioning that after Zhu Di sent a fleet to the Americas, he moved his palace to Jeju Island, and he usually stayed here most of his time. The main reason is that Zhu Di now focuses most of his energy on the ocean. Although Kaicheng is not far from the sea, it is still not as convenient as Jeju Island.

In the study of the Yanwang Mansion, a huge sand table is placed in the middle. This is a map of the entire America, but it is not very perfect. After all, most parts of the Americas are still blank, and they are only marked clearly in some coastal areas. These are the terrain explored by fleets sent to the Americas one after another.

"Prince, we will send another fleet to America this time. If Tongda arrives smoothly, our power in America will exceed the threshold of 10,000 people. However, these people are scattered in several coastal fortresses, and their strength is a bit scattered. I think it's time to build a concentrated city in America." Miao Guangxiao, dressed in black, stood by the sand table and spoke.

Zhu Di was staring with big eyes at this time and was also carefully observing the Americas on the sand table. To be precise, it should be the Central America area. The several fortresses he built along the coast of America were also concentrated on the west coast of Central America.

"It's true that it's time to build the city, but the location of the city needs to be carefully considered!" Zhu Di whispered, touching the short beard on his chin.

If possible, Zhu Di really wanted to go to America by himself to take a look and choose a suitable location to build a city. Only by building the city can he have a real foundation in America.

"The prince said very much, but you can't leave Goryeo for the time being. If you are really worried, don't let me go to America next time." Yao Guangxiao naturally understood Zhu Di's thoughts and immediately smiled.

"Then forget it, I can't live without you!" Zhu Di also showed a helpless look when he heard this, and then pondered for a moment and said seriously, "But seriously, the speed of transporting manpower and materials to the Americas is too slow. It's been so long since we've sent several fleets, but it wasn't until this time that we sent 10,000 people to the Americas. What's this enough for?"

"Your Majesty, don't be too impatient. The route to America has only been discovered for a few years, and the risks at sea are high. We just lost a whole fleet of people and cargo last year. The loss now makes people feel distressed when we think about it!" Yao Guangxiao couldn't help but sigh when he said the last.

The risks at sea have always been a huge uncertainty factor. Last year, Zhu Di sent a fleet of more than a dozen ships, carrying hundreds of people and countless supplies. As a result, the fleet encountered huge waves with high walls, which directly dispersed the entire fleet and ended up almost wiped out the entire army. If it weren't for the lucky crew being swept to a island by the wind and waves and later brought back by passing ships, Zhu Di would probably not know how the fleet disappeared?

"When I was exploring America, Li Jie warned us that the risks at sea are extremely high, so I have been mentally prepared for this. One or two failures are nothing." Zhu Di waved his hand. He was a natural general and had long been used to the choice of interests on the battlefield, so the death of some people could not shake his determination.

"Prince, I heard that a new steamship was created in the Qiuzhen Academy, and now it has started running on the sea. It is said that it only takes three days to go from Taijin to Songjiang. If we can also use this steamship, it will be much more convenient to go to America." Yao Guangxiao suddenly said again.

As the number one strategist around Zhu Di, Yao Guangxiao also kept pace with the times. Zhu Di transferred his power to the ocean, and he would always pay attention to various sea intelligence. As soon as the steam engine ship appeared, he had already keenly felt that this thing would shine in the future, so he wanted to introduce it as soon as possible.

"Li Jie, this kind of steam engine ship, also mentioned it in my letter. However, although this kind of ship runs fast, it requires fuel and fresh water. As far as we go to America, we must set up several ports on the road so that the ship can replenish these supplies. In addition, the performance of the steam engine ship is not very stable, so it may not be used in a short period of time." Zhu Di shook his head and said.

Li Jie wrote to him the first time the steam engine was successfully running. However, although this kind of ship has great potential, it requires time to improve and time to establish ports along the way to replenish supplies. If these two problems are not solved, its performance may not be as reliable as sailing ships.

"So that's the case, the prince-consort is really thoughtful." Yao Guangxiao nodded in admiration when he heard this. Then he hesitated for a moment before asking, "Will the prince-consort reply to the matter in the Naval School?"

"No, last time he replied that he would help me find a solution, but it has been so long, but no news has come." Zhu Di also frowned and shook his head.

The naval school is also one of the things that Zhu Di is most concerned about. After all, if you want to develop the Americas, you must have a strong navy. Now what he lacks the most is naval talents, so he urgently needs a naval school. Although the training of the school will take several years, it is always a stable source of talents, much better than training in the army himself.

"Prince, although I also believe in the character of the prince-consort, it has been so long since he has not heard from him, so I now suspect that his previous letter was just a delay and he didn't plan to help us at all, right?" Yao Guangxiao pondered for a moment before saying again.

"I can't. I understand Li Jie. If he really can't do it, he should tell me directly, and would not use this kind of procrastination method. It's just that I'm worried that he wanted to help us, but he hit a nail in His Majesty." Zhu Di frowned again at the end of his speech. Of course he knew that the biggest difficulty in the Navy School was Zhu Yunyu's attitude.

However, just as Zhu Di finished speaking, he suddenly heard a burst of rapid footsteps coming from outside, and then a young voice shouted: "Father! Letter! My brother-in-law has delivered the letter to you from Beijing!"
