Xiao Rui was overjoyed to learn that his letter had really been received by Xie Mulin. It turned out that he was just lucky, and he was not sure that his sweetheart would definitely receive this letter.

Although there were no love words written in the letter, every word revealed his concern and worry about him, he was so beautiful in his heart that he couldn't help but tell his heart again in the reply, seeing Xie Mulin's face was red, and he must always pay attention to no one entering the cabin to see her current appearance, so as to feel at ease.

Probably because it was estimated that Xie Mulin and his party were about to arrive in the capital, or maybe they were in a hurry and wanted to send the reply to Xie Mulin as soon as possible, Xiao Rui's letter was not very long. But he admitted in the letter that the three princes are indeed facing the problem of the heir of the Yan Wangfu. And because Xiao Rui has maintained a good relationship with King Yan's family for many years, and has worked in the army under King Yan for two or three years, he knows more inside information than Ma Yurong and Lu Feiyun have heard from the capital.

The problem of no heirs in the Yan Wangfu has long been noticed by both the current emperor and the Yan King himself. As the authority of King Yan became more and more powerful, and his influence on the northern army also increased, the emperor always trusted this younger brother, and there was no King Yan without heirs, and according to the royal practice, there will be a prince who will succeed the palace of King Yan in the future. Of course, the emperor is not worried about whether King Yan will be too high and powerful, no matter how powerful he is now, he will also be handed over to the emperor's biological son to inherit in the future, and it is still the emperor who will benefit, and he is stable in his heart!

And to choose which prince to enter the Yan Palace, the emperor also has his own ideas. After discovering that the crown prince was becoming more and more undesirable to him, and the second prince was increasingly exposed to his recklessness and narrow-mindedness, the emperor began to stare at the remaining two sons, intending to choose a satisfactory candidate for the prince. Regardless of which one he chooses in the end, the other will automatically become the candidate for the heir of King Yan. The emperor didn't intend to let either of his two excellent and favored sons become cannon fodder in the battle for the throne.

In the early years, the three princes were still quite popular with the emperor, but the four princes' mothers were not visible, and the concubines were stupid and younger. But now, the emperor may think a little differently. King Yan had received a hint from the emperor, and it seemed that the emperor was more interested in letting the three princes enter the palace of King Yan. The third prince's maternal aunt almost married King Yan as the main concubine, and now Princess Yan and his aunt were also very good friends. The emperor apparently thought that both King Yan and his wife would gladly accept his arrangement.

King Yan didn't say anything about this, but Princess Yan revealed in private that she didn't like Concubine Xiao's personality very much. Although Xiao Guifei is the sister of her close friend Xiao Mingzhu, the relationship between the sisters was very ordinary. Xiao Mingzhu is better to be close to Concubine Xiao Guifei. When Concubine Xiao Guifei was young, she seemed to have done something unkind, offending her sister and Princess Yan. Now that Princess Yan thinks of recognizing the other party's biological son as her heir, she is not very happy in her heart.

Just in case, Princess Yan also proposed that she wanted to settle the marriage of her only beloved daughter, Lord Yongping, and marry her daughter, and then mention her steps. Then, even if the heir is not filial in the future, it will not affect the life of the lord of Yongping too much.

Princess Yan's private remarks were not hindered by His Royal Highness King Yan. Xiao Rui can only guess that he is afraid that his husband and wife, together with the three members of the Yongping County Lord's family, do not have much affection for the third prince, and may not welcome this heir candidate. However, a few years ago, when the county lord of Yongping returned to Beijing with King Yan to see him, he saw the four princes, and they were still having a good time together, and they might be more willing to let the four princes be their younger brothers, but it is not known.

Anyway, before the emperor gave a hint of the heir candidate, Princess Yan and the county lord of Yongping both thought that the fourth prince would be the one who would come to live in the Yan Palace. The latter also maintained correspondence with the four princes in private.

Of course, King Yan and Princess Yan may not be able to be masters on the issue of heirs. They may have a little to offer, but the final decision is in the hands of the emperor. The emperor's favor for the four princes is now very conspicuous, and although the fourth prince is only eleven years old, he is still a child, but he is no longer an age that can be despised by others.

Eleven years old is already very old, and in two or three years, he can follow in the footsteps of his brothers and enter the court to listen to politics. Even now, when he speaks in front of people, it is no longer something that courtiers can ignore at will. It is said that he is very intelligent, and although he has a straightforward temperament, he has a clear mind when encountering problems, is calm, and does things in an orderly manner, and is much more alert than his three older brothers at the same age.

However, he is not a flamboyant child, most of the time he behaves very well-behaved in front of people, even if he is naughty occasionally, he will not be excessive, and he is a likable character. He would not go around befriending dignitaries and nobles, or messing around with the children of the powerful, either staying in his palace to read and learn calligraphy, or accompanying his mother and concubine, restraining her from provoking enemies everywhere. In addition to the time, he would basically accompany the emperor, and sometimes personally wait for his father's food or chat with the palace people, and would never express his opinion on court affairs unless the emperor asked questions.

Therefore, the emperor always felt that the youngest son was filial and caring, and he was indifferent to fame and fortune, and had no intention of power, which was simply to his liking everywhere, much stronger than the first three eldest sons.

Xie Mulin didn't know if the fourth prince was really smart and clever, but if what Xiao Ruixin said was true, he must be a very cautious child. At his age, to be able to do this is already extremely intelligent.

That doesn't mean he doesn't have ambitions.

His approach is obviously in line with the emperor's wishes, as long as he does not make a mistake, the emperor will successfully abolish the current crown prince, and the road to the prince of the four princes will be bright and smooth.

And even if he fails to become a prince in the end, and the successor is another prince, it doesn't matter. Because the fourth prince has never shown any hostility towards his brothers, he has always been a well-behaved and caring little brother. Since the crown prince, the second prince, and the third prince are incompatible with each other, no matter who wins in the end, he must leave a younger brother who is not so deep in hatred as a sign of benevolence and friendship. The fourth prince can also go to the Yan Palace, he has already brushed the favor of Princess Yan and the county lord of Yongping, and he is simply invincible.

And the three princes are still jumping up and down in order not to be the heir of the Yan Palace, resorting to all kinds of conspiracies. Does he really think that the position of the heir of the Yan Wangfu is a hot potato? Smart people don't cut themselves off early.

Xiao Rui does have his own guesses about the future heir of Yanwangfu, but he is not optimistic about the three princes, and he is reluctant to let the three princes go to Beiping to destroy the peace and stability there. However, if it was compared with the third prince becoming the new monarch and destroying the peace and stability of everyone in the world, he could barely accept it, and the third prince would become the future master of the Yan Palace. After all, the Yan Wangfu also has to obey the orders of the new monarch, but the Yan Wang couple has the power to control their own heirs.

It's really not possible, just change someone else. Without the prince, can't you still count on the emperor and grandson? Yan Wangfu commanded the northern border army, and it was normal for a few people to die in battle.

Of course, these words must not be known to outsiders. Xiao Rui just said it casually in the letter. However, in recent days, the resistance of the three princes to the Lan family's family affairs has caused the emperor's dissatisfaction. The emperor issued an edict a few days ago and officially decided on this marriage, and Rao is three princes will not be able to escape no matter how much they jump up and down

Xiao Rui was very happy to see that his cousin was finally able to start a family, and he couldn't wait to express his joy to his sweetheart in the letter.
