Tian Dan often sent a detailed work to the Yan Kingdom to inquire about the news. Hearing that the robbery was to replace Le Yi and let Prince Yan provoke the relationship between King Yan and Le Yi, King Yan instead whipped the prince's affair, so he sighed: "The State of Qi wants to restore the country, it seems that the only way to wait until the new king of the State of Yan takes the throne!"
The change in the situation in the Yan kingdom coincided with the judgment. King Yan Zhao, who liked the art of immortals, made the alchemist alchemy a divine dan, and after taking it, he became ill with internal fever and died soon after. Prince Lezi took the throne and was known in history as "King Hui of Yan".
After King Hui of Yan ascended the throne, Tian Dan immediately sent people to spread rumors: "Le Yi wanted to become king for a long time, but because he was favored by King Yan Xian, he could not bear to betray, so he slowly attacked Ercheng." Now that the new king is on the throne, the Qi people are afraid that the King of Yan will send other generals to attack Jimo."
King Hui of Yan had long suspected Le Yi, and when he heard that the rumors coincided with the words of the robbers, he believed them to be true. So he sent a horse robber to replace Le Yi, and summoned Le Yi back to China.
Le Yi knew that King Hui had been punished for him, and was afraid that he would be killed when he returned this time, and secretly thought that he was originally a native of the Zhao kingdom, and that the king of Zhao had once worshiped himself as a minister, so it was better to abandon his post and return to the Zhao kingdom. So Le Yi left his family in the Yan kingdom and fled to the Zhao kingdom overnight.
When King Zhao saw That Le Yi had come to defect, he was overjoyed, so he sealed Le Yi in Guanjin and called him "Looking forward to the Kings".
After replacing Le Yi with a robber, he immediately changed the deployment of Le Yi and besieged Jimo City. However, the generals of the Yan Army were very tired of war and refused to do their best. Later, Tian Dan set up a deception to deceive and rob, and used the fire bull array to break the Yan army, take advantage of the victory to capture the city of Qi, and restore the state of Qi.
King Hui of Yan was very remorseful, worried that Zhao Guo would use Le Yi to cut down Yan, so he sent someone to invite Le Yi back, and wrote to him: "The last time I recalled the general, I wanted you to rest for a while. The general misunderstood me, so he abandoned Yan and returned to Zhao, so as to be worthy of the kindness of the previous king?"
Le Yi read it, full of emotions, and in order to show himself, he replied to a letter from the "Book of The King of Yanhui": "A good author does not have to be good, and a good starter does not have to end well." The subject did not want to be like Wu Zixu, who not only humiliated himself, but also affected the reputation of the previous king."
Le Yi wrote back that although he would not come back, he would not do anything that had negative Yan Guo. King Hui of Yan then made Le Yi's son Le Jian the "Prince of Changguo" and Feng LeYi's brother Le Cheng as a general. Le Yi also often traveled between Yan and Zhao for the friendship between the two countries, and later he eventually stayed in the Zhao kingdom.
