Recreating the Canglong in the Qin Dynasty

(Qin Shi + Tian Xing Jiu Ge, slow-burning, multiple female protagonists) Traveling through Qin Shi, holding the secret of Canglong Qisu, I originally wanted to be free in the mountains and fields with my junior sister Li Ji. However, the King of Qin whips and snares his throat. This world will not give me any way out! Whatever! Let these seven countries see my methods! Let these various schools of thought listen to my rules! Jing Salamander's sword is for me to use, Xiao Meng's way changes because of me, and Yan Lingji's fire only burns for me! I, Lu Heng! Now we should use this world as a chessboard to recreate the blue dragon!
