Martial Arts: Nourish the Sword with Blood, Stop Killing with Killing

Yan Shisan travels through the Ming Dynasty's mixed martial arts world, activates the "Great Ranger System", and is rewarded with the full-level "Secret of Immortality" at the beginning. ​Complete the Grand Ranger system tasks, and the system will randomly send rewards. "Secret of Immortality", "Pictures of the God of War", "Songs of the Blue Sea Tide", "Zhenlong Chess Game"... Yan Shisan is versed in the Five Classics, is accustomed to the Six Arts, and integrates the best of hundreds of schools of thought to create his own "Thirteen Deadly Swords." Thirty springs after being drunk in the world, how could I find a book and a sword to understand the world of mortals? I visited heroes all over the world and defeated invincible opponents in the world. Unknowingly, Yan Shisan was standing at the top of the martial arts world.
