The two heavy medicines that the old lady doctor used at the beginning cannot be said to be wrong. After all, it was important to save lives at that time, and the two flavors of medicine did play a big role, removing half of the poison from the four princes. If it weren't for these two heavy medicines, it was still unknown whether the four princes would be able to get better so quickly.

But his age is here, and it is normal to have sequelae. If it weren't for this month, the people who were waiting next to the four princes felt a little strange, and mentioned it to the four princes, and the four princes themselves might not have imagined that there would be problems with them. For the sake of his own health, he didn't hide the truth and told the old doctor directly. The old doctor took his son to look through the medical books collected at home, only to find that there might be something wrong with the two medicines. It's not that these medicines are poisonous or wrong, but they are too violent, and for the young four princes, they are somewhat damaging. It's just that detoxification was the first priority at that time, even if the old lady doctor knew that this medicine might leave a legacy for the four princes, and when he couldn't find a suitable substitute, he could only continue to use them.

King Yan told Zhu Rui: "Whether the aftermath of this medicine will really affect the future heirs of the Fourth Highness depends on the situation in three or four years." At that time, the fourth highness was also approaching adulthood, and he could marry a wife and have children, and if there was anything wrong, it would be revealed. Until then, no one could be sure that the Fourth Highness had indeed been damaged by the effects of the medicine. But even if his body is really damaged, it cannot be said that the aftermath will never be eliminated. Maybe there is a doctor who prescribes good medicine and regulates the four highnesses for a few years, and he will be fine, and it will not affect the heirs? ”

Zhu Rui heard the meaning of King Yan's words: "But this kind of thing can't be said accurately at all!" Once the emperor thinks that the four highnesses may be cut off and unable to have heirs who can inherit the throne, it is possible to choose another prince to inherit the throne for the sake of the royal family. Father thinks that the emperor may choose the third highness instead, because no matter how bad the third highness is, he is better than the crown prince?! ”

King Yan sighed: "Even if His Royal Highness the Crown Prince does not have the Cao family, a mother clan with evil intentions, his own temperament is not suitable to be the king of a country. He is both self-willed and stubborn, and he does not listen to advice. If he has to ascend to the throne, it is very likely that he will become a faint king! Moreover, there is the Cao family behind him, and since the emperor ascended the throne, the Cao family is the most feared. It took him more than ten years of hard work to suppress the Cao family, how could he watch the Cao family rise again?! Therefore, even if the emperor doesn't like the temperament of the Third Highness, for the sake of the overall situation, he may choose the Third Highness to succeed him. As long as His Royal Highness swears that he will not harm the other brothers, then the possibility of the emperor favoring him is even greater! And for the Third Highness, if he can really inherit the throne, why should he be like his brothers? Nature is happy to make vows. ”

Zhu Rui wanted to speak again and again, but finally said it: "Even if the Third Highness really makes an oath, he will not really want to keep his promise." He is narrow-minded and has never allowed others to be disobedient, not to mention that several princes have been expected to become princes and have been his hindrances? When he sits firmly on the throne, the oath should be forgotten. Even if it is for the sake of the government and the opposition and his reputation in history, he will not openly order the execution of his own brothers, and he will also think of another way to kill him! ”

King Yan paused, knowing that this son had been with the three princes day and night, and grew up together, and naturally had a deeper understanding of the three princes than others, and he would come to such a conclusion, which had his own reasons. But even so, King Yan still thinks that the possibility of the third prince succeeding to the throne is not small: "The emperor may not think that his son is such a wicked person who does not keep his promises. The emperor is disgusted with the Cao family and the crown prince, and he is better than others, he will be willing to take this risk, it is better than the fourth highness succeeding to the throne but cutting off the heir. ”

Zhu Rui thought for a while: "The Fourth Highness is still young, and he is slowly adjusting, and he will not be able to raise it for ten or twenty years." Twenty years later, he was only thirty-two years old, just in the prime of life, and he had time to cultivate the imperial heir at that time! At the moment, it's just that the emperor may not be able to wait for that day, so he doesn't dare to take risks. can take 10,000 steps back and say, if the Fourth Highness really has no children, it does not mean that he will cut off the heir, because he can still pass the heir! The first emperor is the heir to the royal family, there is a precedent, who said that the four highnesses can't follow suit?! ”

King Yan glanced at his son deeply: "Chonglin, do you know what you're talking about?" Do you know that if His Royal Highness really wants to have a step-heir, which family is he most likely to choose?! ”

Zhu Rui opened his mouth, and then fell silent.

If the emperor refuses to let the crown prince succeed to the throne, it is impossible for the four princes to let the prince's heir become their heirs, so as not to make the Cao family make a comeback, or cause turmoil in the succession to the throne; The second prince has already been succeeded, and the etiquette is already a distant branch of the clan, so let's not mention it for the time being; The three princes are ambitious, and it is very likely that they will inherit the royal family through their parents and children, and all kinds of incidents will arise. In this way, it is not appropriate for the four princes to succeed the heirs of their own brothers.

The next royal branch closest to the bloodline of the four princes is the emperor's half-brother, the current Yan King who was succeeded to the Yan Palace! And King Yan has only one son. This means that if the four princes want to pass on their heirs from a clan that is close to each other, the most likely one is Zhu Rui's son!

After thinking about this, Zhu Rui didn't dare to say anything more. He couldn't even make this suggestion to the Four Princes! That would only make the four princes suspicious of him. The fourth prince is only twelve years old, and he may not be able to have his own son in the future, so why did the son of King Yan start the idea of succession first? Does the Yan Palace's support and help to the four princes also have their own selfishness?

Once the four princes have suspicions about Yan Wangfu and Zhu Rui, even if the four princes succeed to the throne safely, they will not have any good fruits to eat.

Seeing that his son was silent, King Yan knew that he understood the sensitivity of this matter: "Chonglin, you also thought of it, right?" This matter must not come from the mouth of you, my father and son, and even the princess and Yong'an cannot reveal a little bit of tone! If one day, the emperor or the fourth highness really asks you and me if we need stepchildren, then we can only push others out, for example...... Second Highness! He is the elder brother of the Four Highnesses, and he is closer to the Four Highnesses than you and my father and son! ”

Zhu Rui raised his head: "The son will only be silent and tell the emperor or the fourth highness that the Yan Wangfu will act in accordance with the holy decree." Although the Second Highness is the elder brother of the Fourth Highness, firstly, he has already been succeeded, and secondly, he is not a suitable candidate in terms of temperament. In the past, when he was still a prince, he was not less confused. Now that he has suffered a great change and is constrained by his mother and sister, he has just become honest. Once his son becomes the heir, he may not be free from right and wrong. What's more, in the past, as the elder brother of the Fourth Highness, he also bullied the younger brother, and the Fourth Highness would probably not be happy to accept his heir. ”

"These things have their own four highnesses to consider." King Yan approached his son, "Anyway, you are not allowed to come up with ideas." No matter what you think in your heart, you can't say anything about it. Without twenty or thirty years of hard work, no one can say that the Fourth Highness will definitely cut off the heir. ”
