"Of course, Erchen knows that Japan is an island country, and in the northeast of our country, there is Goryeo to cross the sea." The prince hurriedly replied.

The emperor never liked Confucianism, and under the emperor's personal inquiry, the education of the prince was no longer taught the Four Books and Five Classics as he did back then, but only taught some literature a little, so that the prince knew how to write and write and poetry, but taught a lot of mathematics, geography and other knowledge, some of which were taught by foreign missionaries in person, so of course the prince was not confused about the situation in the surrounding countries.

"My father has already decided to attack Japan in the summer and autumn of next year." The emperor continued to look at his son, and a rather playful smile appeared on his face, "And you, when the time comes, will be in Goryeo, the rear of the commander-in-chief." ”

Sit in Goryeo, the rear of the commander-in-chief!

Although the emperor said it very plainly, for the crown prince, this was tantamount to a thunderstorm, he didn't expect his father to hand over such a major task to him.

"Father...... the crown prince smacked his tongue, and found that he was a little dry-mouthed, "This ...... Is this true? ”

"Of course it's true, you don't joke, would I use this kind of thing to entertain you?" The emperor's smile deepened, looking at his son so surprised, he seemed to have some evil taste satisfaction, "You, although you are still young, but you are always the prince of a country, how can you be so easily impetuous?" You need a little more concentration! If this is the case, how can you go out of town and intimidate the vassal kingdom? ”

"Erchen...... Wrong. At the urging of his father, the crown prince slowly regained his composure.

But until now, he still had a strange feeling.

Father, are you going to let me out of town and take the rear of the commander-in-chief? And send me to Goryeo?

The crown prince did not ask why his father decided to attack Japan, because he knew that his father was extremely wise, and he would definitely have his own big reasons for making a big decision—sending himself to the rear of the main town, and it would definitely have a deep meaning.

Perhaps, I plan to let myself experience some experience and pave the way for learning to govern the country in the future.

After the initial excitement subsided, it was replaced by a kind of uneasiness, can I handle such an important task as my father? If it doesn't do it well and ruin the emperor's plan, how can it be good!

"What? Out of sorts? Feeling uneasy? The emperor was still smiling, as if he could see through what the prince was thinking, "Scared? ”

"Erchen...... Erchen was indeed a little apprehensive. The prince honestly replied to his father, "The son is afraid that he is young and lacks ability, and he will spoil his father's plan......"

"It's normal to be afraid, at your age, it's strange if you're not afraid." The emperor lovingly wiped the prince's hair again, "But, son, you are the prince, so you can't be afraid." Even if there is a heavy courage pressed on your body, you can't be afraid, you have to grit your teeth and hold on, and move forward little by little against the wind and waves, only in this way can you bear the burden of the world! When my father was as old as you, didn't he already start to bear the burden? Don't be afraid, you are my son, I can stand up, and you can stand up too! ”

"Don't be afraid, you are my son, I can stand up, and you can stand up too!" This heartfelt encouragement once again shocked the prince's spirit.

Yes, he is the emperor's son-in-law, but also his most favored and most highly anticipated son, no one knows more about the emperor's history than him, from his father, from the mouth of the mother, he knows that his father was in Xuzhou at that time from how difficult the situation little by little, and finally swept the world with the brothers around him, and founded a new dynasty. The hardships and the pride, how could he not be fascinated?

It can be said that he admires his father very much, and he wants to prove to his father that he is worthy of his father's love and is worthy of being the successor of the world.

So, with such an opportunity, how can I back down? The prince thought to himself.

"Thank you for the reminder, son...... Erchen knows that he is wrong! Thinking of this, the crown prince couldn't help but straighten his waist, "Erchen must do his best to handle all affairs well, so that his father's plan can be successfully completed!" ”

"Okay, just have this picture, how can my Zhao family's children do without this breath!" The emperor laughed again and patted the prince on the shoulder, "However, it is not enough to be angry, you still have to talk about the method of doing things." I will match you with some people, you just have to use them well, you are the prince, as long as you use good people, there is nothing bad to do. ”

After speaking, he seemed to recall some things back then, and sighed again, "Think of me back then, how could anyone give me any team?" Isolated and helpless, I can only rely on myself to shoot my brother with a stick, play the team, and finally fight this country step by step, son, you have better conditions than me back then, I don't know how many times, but you have to cherish it! ”

This serious teaching, in addition to emotion, I don't know how many expectations are hidden, the prince listened to his nose a little sour, but he stubbornly endured it.

"Father, the son knows that the father has good intentions, and the son will never live up to his father's expectations!" This young man, who was not very tall, sat next to the emperor and shouted out with enthusiasm.

"Okay, okay." The emperor smiled, then stood up, took out a document from his desk, and handed it to the crown prince, "This is a piece of information about Li Hui, the lord of Goryeo, and some of his children and close ministers, you take a look when you go back, familiarize yourself, next year you go to Goryeo, you have to deal with the Goryeo people, as soon as you figure out the name, it is good that it will be convenient to do things at that time." Japan's relevant regulations, I also instructed people to do it, and when it is done, you can also take it and take a look, knowing yourself and knowing your opponent can win all battles. ”

The prince respectfully took these strips of Chen, put them in his arms, and began to read them when he was ready to go back and had time.

Because Goryeo was a neighboring vassal state, the crown prince now had some understanding of the situation in Goryeo. Since July 16, the 25th year of Hongwu, the Goryeo general Li Chenggui abolished the Goryeo Gongrang king, and ascended the throne in Songjing Shouchang Palace, and then Li Chenggui reported to the Ming Dynasty with the title of "right to know state affairs", so it became a vassal state of the Ming Dynasty from the beginning of the country.

After Li Chenggui ascended the throne, his second son Li Fangyuan was named the King of Jing'an. After two princely rebellions, he was named the prince in the second year of Jianwen, and on November 13, he was conceded by his eldest brother Chan in Songjing Shouchang Palace. At this time, Zhu Di, the ancestor of the Ming Dynasty, gave King Li Fangyuan a decree, and the prince's nine-chapter crown dress, and his title changed from his father's "right to know state affairs" to king, and since then, every time the new king of Goryeo ascends the throne, he needs the confirmation of the Ming court.

For the next 200 years, Goryeo regarded itself as a vassal state of the Ming Dynasty and treated the Ming Dynasty very deferentially.

In the Wanli period, Toyotomi Hideyoshi, the minister of the autocratic power of Japan, crossed to the west and landed in Goryeo, in a vain attempt to annex Goryeo first and then march to the mainland to seize the world of the Ming Dynasty. At this time, the Wanli Emperor sent troops into Goryeo, and after years of hard fighting, he finally drove the Japanese army out of Goryeo and sent the royal family back to the national capital.

However, after the rise of the Jurchens, Goryeo also sent troops to attack the Jurchens with the Ming Dynasty at the beginning, but because the Jianzhou Jurchens repeatedly defeated the Goryeo and Ming armies, the then lord Li Hui began to start at both ends of the rat and no longer intervened in the war between the Jurchens and the Ming Dynasty, and because Li Hui had indiscriminately killed dissident ministers in Goryeo for many years, he had already gone up and down, so in the third year of the Apocalypse, in the spring, Li Liang, the nephew of Ayayangjun who was working around Li Hui, saw that Li Hui was ill, and contacted outside supporters to launch a palace coup d'état, and made Li Hui the king of Guanghai, He proclaimed himself the lord of Goryeo. On the morning of March 13, the day after the palace coup, the twenty-eight-year-old Ayayang-kun Li Liang was in the separate hall of the Gyeongun Palace, while the deposed Gwanghae-jun was blinded by lime and exiled to Qiao Tong on Ganghwa Island.

A few years later, the new dynasty was established, and Goryeo was reunited as a vassal to the new dynasty, but the new dynasty did not accept Yi Liang's means of seizing the throne through a coup d'état, so he asked Li Liang to return to the throne to Li Hui. Although Li Liang pleaded in every possible way, and finally even took the risk to resist with arms, but under the deterrence of the imperial court, none of the civil and military ministers of Goryeo dared to resist the will of the imperial court, so he launched a palace rebellion, deposed Li Liang, and welcomed back Gwanghaejun who had been exiled to the outer islands.

Gwanghaejun, who was already blind, was re-established as king, but after all, he was blind and became disabled, and there were many inconveniences in governing the country, and he was already old, so after he ordered the execution of Li Liang and his family and relatives, he did not care about the political affairs of the country, but entrusted the affairs of the state to his ministers and the Han envoys stationed in Seoul.

The envoys stationed in the vassal states were also an innovation of the Han system, because they were dissatisfied with the Ming Dynasty's practice of basically ignoring the vassal states except for some tributary affairs, the Han Dynasty decided to send missions in the vassal states at the beginning, while proclaiming the will of the imperial court and implementing remote control management of the vassal states, while making them act more consistent with the Han court. Of course, only a few vassal states, such as Goryeo and Ryukyu, have started to do so, and they have not yet expanded to all of their neighboring countries.

Therefore, the envoys of the Han court stationed in Goryeo had already played a decisive role in manipulating the state affairs of Goryeo, and this situation was very favorable to the prince's mission in Goryeo, and there was no doubt that in order to cater to the prince, the embassy in Seoul would do everything in their power to force the Goryeo people to cooperate.

Moreover, they have been stationed in Goryeo for a short time, and they have a little understanding of the affairs and specific situations of Goryeo, and after the prince arrives there, he can also control Goryeo through them, not only in the next year's attack, Goryeo can be effectively turned into a base for attacking Japan, but also after the war is over, Goryeo can be more closely integrated into the Han system.
