Baby Alliance: Demon Lord, Please Take the Bed

He, the mysterious and unpredictable Demon Lord, possessed countless identities and moved with strange traces, yet he doted on her to the very marrow of his bones. "Mother, baby likes that one!" The little treasure blinked her adorable eyes, pointing at the Ninth-Grade Demon Crystal on a certain man's body. The certain mother didn't even lift her eyes. "If you like it, take it. If you can't take it, snatch it. If you can't snatch it, kill for it!" And so, the little treasure returned home laden with spoils. "Good daughter, quickly call me Father." The male protagonist patiently coaxed the little girl before him. "Mother said calling 'Father' costs five thousand gold. How many times should I call you?" The cute little girl looked calmly at the man in front of her, pulling a small abacus from her pocket. "Call me for a lifetime." The male protagonist pointed without hesitation at the certain woman not far away. "Your mother owes me money for a lifetime; you just go and demand it from her."
