Raw Rice Is Cooked into Popcorn, What Else Are You Doing in the System?

I've already given birth to that bastard. You tell me the system is coming. After traveling through the realm of immortality, I became a prisoner of the Demon Lord and was forced to give birth to his child. He treated me with gentleness and respect, but I believed that I was just a furnace for his cultivation. Until the system comes: "The ultimate mission: completely defeat the Demon Lord, current favorability: 90%." I stared at the babbling child in my arms, and then looked at the Demon Lord outside the door who was holding the soup and carefully blowing it to cool down. I was completely confused—— So all these years, he actually really likes me? !
