Because Fan Ye saved Jiang Taixu. In the anime "Covering the Sun", Fan Ye can become an emperor without the help of Jiang Taixu. This is because Fan Ye helped God King Jiang Taixu escape from Zishan, so God King Jiang Taixu was very grateful to Fan Ye, so God King Jiang Taixu helped Fan Ye wash the curse with his own blood, which was also the greatest help to Fan Ye, so it was because Fan Ye saved Jiang Taixu. Jiang Taixu is a character in Chen Dong's novel Covering the Sky, and one of the few characters in the novel. He was as lonely as snow in the mighty sense of justice, and he remained lonely all his life.
