How did Lu Ye Chu persuade Tuo Lei to agree to Khan's position?

1229, Zong Rui Tuo Lei has been in charge of this country for two years. According to Genghis Khan's wishes, the throne should be passed to the third son of Mao, Wokuotai, but there is no sign that Tuo Lei will hand over power. As a wise assistant, Lu Yechu clearly realized that hanging sweat in vain or putting it in the wrong place is not good for the country and the people. Therefore, Yeluchucai and Wokuotai discussed the resolution to hold the "Messenger Conference" as soon as possible. Genghis Khan once had a unique legal system: when the old and the new were handed over, every Mongolian Khan had to be confirmed after the royal generals and their ministers convened an open meeting.

In the autumn of this year, Genghis Khan's prince and relatives gathered by the Krulun River to discuss the succession of Khan's post. The meeting lasted for 40 days, but it was still up in the air. Yeluchucai thought that this matter could not be delayed for a long time, so he personally remonstrated with Tuo Lei: "This is a national event and should be decided as soon as possible." Tuo Lei said, "We haven't reached an agreement yet. Can we choose another auspicious day? " Chu Cai said, "After this day, there will be no auspicious day." So we decided to establish a set of etiquette system for ascending to the throne.
