I Got a Son-In-Law at the Beginning, and the System Forced Me to Have a Wet Nurse!

[Travel + Immortal Cultivation + System + Single Female Protagonist + Funny + Double Strong + Schizophrenia] I traveled through time to become a son-in-law, and the system actually forced me to be a baby daddy? Okay, it's just a part-time job, I can bear it! Others traveled through time to cultivate immortality, while I traveled through time to become a son-in-law, and I was also bound to a [Nanny System]! His cultivation was locked at the level of Qi training, and his only task was to take care of the nanny with a mysterious identity and extraordinary figure. Breastfeeding, changing diapers, telling bedtime stories... I worked diligently as a social animal in the fairy world, just to save enough points to resign and return to earth. But can anyone tell me why I was able to kill the Jindan Patriarch with one stick using the "fire stick" rewarded by the system? Why can the "heart protection goggles" I bought for my wet nurse resist Yuan Ying's self-explosion? Is it really the system and not me that is sick? The entire immortal world thought I was a loser who clung to the wet nurse's lap. Until that day, the Immortal Emperor came and respectfully shouted to me: "Master, you've had enough fun, it's time to go home." Me: "??? My KPI hasn't been completed yet!"
