Ji Hong was only a temporary generation.
Perhaps Xia Longwu felt that no one could be called the seventh generation, so he didn’t set up a principal.
The first generation Xia Chen created the multi-divine text.
The second generation Imperial Beast technique was incomparably powerful, subduing the giant dragon.
The third generation was invincible in the DAO, transforming into mystic armor.
The fourth generation was unparalleled in the forging of weapons, and was also incomparably powerful.
The fifth and sixth generations were all fierce people who could kill invincible people. Each generation was stronger than the last. Now, who in the Great Xia mansion could bear the title of the seventh generation? Unless Xia Longwu himself was more or less the same.
