Fantasy: Refining the Immortal Sword at the Beginning

Yi Qian traveled to another world. He thought it would be difficult to survive in a world where everyone is a practitioner and there are ferocious beasts everywhere. Unexpectedly, the ancient idle system was activated. Hang up and upgrade, dropping various rare materials and god-level skills. Yi Qian is getting stronger every moment. Facing an opponent two levels higher than himself, Yi Qian silently pulled out the acquired immortal sword he had just refined. What, there are actually opponents that the Immortal Killing Sword can't kill instantly? Then I have to spend some glory points to upgrade it to an innate spiritual treasure... If it really doesn't work, let's not upgrade the twelfth-grade lotus platform for now, and simply upgrade the Zhuxian Sword to the Chaos Arcana. This novel and its characters are purely fictitious.
