Comprehensive Martial Arts: the Prince of the Song Dynasty, the Invincible Swordsman

Song Chuan accidentally traveled to the world of mixed martial arts and became the prince of the Song Dynasty. In this world, countries compete for supremacy and martial arts are in turmoil. The Song Dynasty was weak and its rulers and ministers were immoral. How could they resist foreign enemies? Song Chuan abandoned literature and embraced martial arts, vowing to wash away the humiliation and reshape the Song Dynasty! Shu Zi, who has a good look, has accepted a thief as his father, how can he have the dignity to live in this world? Murong Fu, who was ambitious but incapable, still wanted to restore his country? But it's just a fool's errand! The emperor's incompetence has caused chaos in the world. I, Song Chuan, ask your majesty to abdicate and die!
