The Demon Ancestor was able to refine the Immortal Slaying Four Swords using Sumeru Mountain, so naturally, Jiang Chen could do so as well. However, the sword he aimed to refine was not the Immortal Slaying Four Swords but rather the Innate Treasure, the Hongmeng Slaying Sword.
At that time, Jiang Chen, in order to fight his enemies, had traversed space and time, borrowing power from the future.
His future self used the three innate Divine Swords—Taichu, Dutian, and Pure Yang—to evolve the three paths of Heaven, Earth, and Humanity, thereby refining the Innate Treasure Hongmeng Slaying Sword, which possessed the ability to obliterate heaven and earth and return everything to the primordial Hongmeng state.
From that day onward, Jiang Chen had secretly noted this matter and continued to harbor the ambition to refine the Hongmeng Slaying Sword.
Unfortunately, after a hundred years, there was still no sign of the Hongmeng Slaying Sword taking shape.
