After a Night of Love, My Mortal Enemy Took Possession of My Baby

I, the mighty Demon Lord, slept with a handsome sword cultivator. Unexpectedly, this sword cultivator is my mortal enemy - Sword Sect N0.1. He chased me for hundreds of kilometers, and my scumbag said: "Aren't you happy? Why am I responsible?" He was furious: "I'm pregnant and the baby is yours." I pick at my earwax: "Why are you, a man, pregnant?!" Intention: Parents' love is very good
