The First Sword of the Tang Dynasty: Where Should I Swing the Sword?

At the age of sixteen, Qi Feng entered Chang'an with his sword on his back. He has a mysterious "Martial Arts Realm" where martial arts from all over the world can be learned at a glance and practiced a thousand times. He originally thought that if there was any injustice in the world, it would be cut off with one sword. Until he met a young man who called himself "Li San". Later, that person became Li Longji. And Qi Feng also became the world-famous No. 1 Swordsman in the prosperous Tang Dynasty. He has killed powerful men, beheaded powerful men, broken military formations, and taken the rank of general among thousands of armies.

By the Wei River, young Li Longji once asked him: "What if one day I do something wrong?" Qi Feng said: "Then I'll tell you." Decades later, he really came. The best sword in the world, where should you swing it?
