"Emperors, today I will choose one of the five of you to be the crown prince, I will only ask one question, you write your answer on paper, no one is allowed to look at anyone," the emperor said solemnly but slightly blandly, "The question is, how to rule the world, let's start!"

After listening to the question, Zi Zhao's four royal brothers all looked very proud, and then began to write down their answers, but Zi Zhao seemed very bland, but he also wrote his own answers.

The emperor then said, "All the answers are finished, then give me your answers!" and then they all handed in the answers.

When the emperor saw Zizhu's four royal brothers' answers, they were all expressionless, but when he saw the viscount's, his face was slightly surprised, and he was more happy. It turned out that the answers of the four imperial brothers were all "Wu", but Zi Zhao's was "heart".

"Now explain your answers. The emperor said calmly. "Ruling the world by force is the style of the emperors of all dynasties!" The four imperial brothers were in unison. "Zi Zhu, what do you mean by writing the heart?" the emperor asked the viscount again.

"Back to my father, the heart is the heart of the people, but also my own heart, to rule the world with the heart, to the heart of the people, to govern the world without spending a soldier, the whole country is the people, the people's heart is like water, can carry a boat, can also overturn the boat, only is the people's will, there is a peaceful and prosperous world, if it is against the people's will to do it, it will be the death of the country, although the country can be governed by force, but it will cause the loss of the country, since it is not necessary to use a soldier or a foot to obey the people's will, why use force!" Zi Zhao replied calmly.

"Fifth brother, are you too weak, if you obey the people's wishes, what if they are against them?" Wang Ziwu was very unconvinced when he heard it. "Brother Huang, the people's desire is peace, if there is a rebellion, we don't need to do it, the people will help solve it, after all, no one wants to have a war!" Zi Zhao replied lightly.

"Okay! Okay! Good! Very good! Come, pass the order, I want to make the fifth prince the crown prince!" After listening to Zi Zhu's explanation, the emperor said a few good words, but Zi Zhu's four imperial brothers were very surprised when they heard that the fifth brother was going to be appointed as the crown prince, thinking that his father would not have made him the crown prince because of the words of the national teacher, otherwise how could such a coward be made the crown prince! The emperor seemed to see their doubts and said: " What you said is not entirely wrong, indeed, the world can be ruled by force, and it can also cover the world, war is the most feared and least desirable of the people, just like why did the father and emperor raise troops, just because he wanted to let himself, let the people live a stable life, the war brought to the people is the misery, what if you win, sooner or later the country will die if you do not follow the will of the people, so, as a ruler, the rule is the people's heart, only in this way can you do the whole country are soldiers, so as to surrender the soldiers without a fight, the father emperor originally raised troops to establish this new country is just a foundation, only in this way can he make his own system, the father is also obedient to the people's will, in order to clean up the countryIn the end, the other neighboring countries not only did not start a war against our new country, but instead bowed down to their vassals, which is to govern the people and rule the world!"

"Zi Zhao is not cowardly, but knows what it means to respect and forbear, I saw when you were the eldest brother of the emperor and deliberately made things difficult for Zi Zhuo, and in the end you lost the competition with Zi Zhuo, although Zi Zhao soaked in the pharmacy all day long, but let him develop a good heart, the heart of the doctor's parents, how is governing the country not to treat people!" The emperor said to Zi Zhu's eldest brother amiably but majestically.

Wang Ziwu was very embarrassed when he heard the emperor's words, but he had a little more hatred for Zizhuo, he had always worked harder than his fifth brother, but his father never let go of his eyes, but he didn't dare to show it.

On the same day, the emperor announced to the whole country that the five princes were the crown princes, and although the people did not know what happened to the five princes, they believed in the current emperor, because his clean government and governing system were enough to make them believe that the five princes were not bad.
