The Heartless Sword Venerable Keeps Outliving His Dao Companion

The Swordmaster once had five Dao companions, and they all died. The Demon Lord had five incarnations, and they were all hacked to death. Betting pools have opened all over the cultivation world: When will the Swordmaster kill his next Dao companion? Then the Demon Lord proposed to the Swordmaster. And the Swordmaster agreed. So now the betting pools have changed: Will the Swordmaster kill the Demon Lord first, or will the Demon Lord kill the Swordmaster first? A Swordmaster bottom who kills his husband to attain the Dao and follows the merciless path. A Demon Lord top who is a secret-identity-collecting split-personality maniac. Blurb to be revised. Just so nobody gets the wrong idea, killing one's husband to attain the Dao means exactly what it says. They really do try to kill each other.
