What is my 1000-year-old monster self to do when I’ve failed my immortal ascension? Time travel — accidentally — and wind up back in my 9-year-old body, needing to re-cultivate, of course. But after that? Get REVENGE! Muahahahaha! But the idiot who killed me — also accidentally — was the main character of the dumb harem Xianxia I transmigrated into. But wait. Wasn’t he only 7 or 8 at this point in time? Well, since I can’t harm a child or the main character without suffering in some way, then I’ll just have to raise him better, faster, stronger, and loyal! Muahahahaha!

As the other person’s stand-in, he humbly falls in love with the president.

Xue Yingshuang was a stand-in, and humbly fell in love with Xing Yun…’s salary pay.

As the other person’s stand-in, Xue Yingshuang wishes he could never be separated from the president for the rest of his life.

He is a stand-in, and he must get off work at one o’clock.

The president’s white moonlight came back, other stand-ins were sad, and depressed. They couldn’t handle the jealousy and finally left with a dead heart.

Xing Yun’s white moonlight came back, and Xue Yingshuang had no waves. He enthusiastically served white moonlight and shone brightly at work.

Xing Yun: Little stand-in, is this your little trick to seduce me?

Xue Yingshuang: Misunderstood.

Xing Yun: Do you want to suffer in silence and finally leave secretly, driving me crazy?

Xue Yingshuang: You think too much, how can I leave? I still have half a year of social security before I can receive unemployment insurance.

Xing Yun: ?

Xue Yingshuang: I also haven’t received the year-end bonus you sent me yet.

Xing Yun: ??

Xue Yingshuang: I didn’t get my paid annual leave either.

Xing Yun: ???

Xue Yingshuang: Wait until I get the money and put it towards a vacation.
