Douluo V I Can Change The Martial Arts Of Girls

Qin Ye, who traveled through Douluo, obtained the system. As long as a girl can raise the trust level between himself and the girl to 90% before awakening the martial spirit, then Qin Ye can change the girls' martial spirits.
But all the girls have been titled Douluo. Qin Ye is still at level 30. His martial soul is the Holy Dragon of Light. He is obviously a martial soul of the bloodline of a divine beast and has innate soul power. However, he is stuck at level 30 and cannot make any progress.
Reluctantly, Qin Ye could only create the Black Moon Courtyard, and wait until all members were titled Douluo before it was released.
But contrary to expectations, the Heavenly List came to the world, and the Black Moon Courtyard founded by Qin Ye could not stay away from it.
