I Become Stronger When I Wash My Sword, the Sword Ancestor Treats Me as Medicine

As soon as Lin Bei traveled to another world, he was sent to the Sword Washing Pond by the Wanjian Sect. Here are piles of countless broken swords brought back from battlefields and secret realms, the sword bodies stained with demon blood and sword evil. The handymen who went into the pool with him died tragically one after another, but Lin Bei accidentally awakened the Heaven-casting Sword Pool. Wash away the sword evil and you will get the sword essence. After cleaning the fierce sword, you can also get the sword marks and inheritance left in the sword. So others washed their swords and lost their lives, but Lin Bei washed his sword and became stronger. From ordinary broken swords to ancient ferocious soldiers, from Waichi handymen to sect sword cultivators, the swords Lin Bei washed became more and more dangerous, and his cultivation level became higher and higher. Until he took on a big job that no one dared to touch and washed away a broken black sword sealed deep in the cold pond. Under the broken sword, Leng Qingxuan, the Supreme Sword Emperor of Wanjian Sect who had been missing for many years, was sealed! What's even more terrible is that Leng Qingxuan was poisoned by Xuan Yin. The first thing he did after waking up was to drag Lin Bei into the cold pond... Afterwards, Lin Bei thought the two would never see each other again. But he soon discovered that the sword essence he obtained from washing his sword could suppress Leng Qingxuan's Xuanyin backlash. From then on, the aloof Supreme Sword Emperor would appear in the sword washing pool every now and then. Lin Bei couldn't bear it anymore and asked face to face: "Senior, what do you think of me?" Leng Qingxuan held her sword in front of his neck, with no trace of emotion on her face. "Medicine." Many years later, Lin Bei took charge of the Heavenly Sword Pond, with thousands of swords roaring behind him. Leng Qingxuan stood beside him and changed her words lightly: "Also a husband."
