I Was Cleaning My Sword in Jiejiao, and Master Tongtian's Mentality Collapsed.

[Prehistoric] + [System] + [Invincible] + [Shuangwen] + [Swordsmanship] + [Qi Ling Niang] Gu Han traveled through the wilderness and happened to catch up with the leader of Tongtian who was trying to transform the four swords of Zhu Xian. As a result, the Zhuxian Sword Spirit's form went awry, becoming insane and out of control with murderous intent. In order to suppress the sword energy, Tongtian married the sword spirit "Su Su" to Gu Han, a human being with an innate sword body. Gu Han discovered that as long as he fed his "wife" blood, bathed her (sword cleaning), and coaxed her to sleep (nurturing her), he could gain astonishing insights into the way of the sword. Facing the great sage of the demon clan? Gu Han calmly untied the cloth behind his back: "Madam, please draw your sword!" The cold light of a sword shines across the nine states, and all the saints are like ants!
