Rebirth and Exchange, I Use My Wife's Body to Become a Sword God

I, Ye Zhanfeng, am an undefeated swordsman, but I was betrayed by my wife Qin Wanyue, and I died together with my enemy. After being reborn, I vow to make her pay with her blood! But when I opened my eyes, I was confused. In the mirror, there was that beautiful face that I hated so much. And "I" myself was standing opposite, looking at "her" with the same horrified eyes. We... Actually swapped bodies! What's even worse is that the enemy from the previous life has come to kill him! She, a "vase" who has the body of my sword master but can't even hold the sword steadily, how can I resist her? What can I do, an unlucky guy who has the soul of a sword master but is trapped in a "spiritual waste body"? When I was in despair, I was shocked to discover that this "wasted body" that everyone laughed at turned out to be the legendary [Chaos Dao Fei] that was never seen in ten thousand years! The cultivation speed is a hundred times that of men! You can learn any sword technique in one go! And she gradually showed her amazing fighting intuition, using my scarred body to create wild sword moves that even I had never imagined! We were forced to work together, teaching each other how to use our bodies and how to impersonate each other in front of the world. Through the ridiculous coexistences and life-and-death battles, I gradually discovered that the "betrayal" in my previous life seemed... To be a huge misunderstanding.
