[Silas Griswold has met all requirements to become a host] [System binding... ] [To complete binding host needs to complete three quests] [Congratulations, you have completed all quests ] [System binded successfully] [Your evolution will now begin!]

[Simulation] + [Isekai] + [Goblin] + [Harem]After a long sleep, I awakened in a new life—as a goblin. Weak and insignificant, I found myself reborn as the lowest creature in a world filled with hostility and danger. But from the shadows of this cruel world, a silent rise begins...

After a series of life-changing events, Pei Ge decides to start anew and rediscover her place in this world. She gets a new job, new friends and… a new boss whom she mistakes as a male host!

He helps her to get revenge on a back-stabbing friend, supports her when it seems that the world has given up on her, encourages her to be more confident about herself and even… messes up her blind dates!

With her strong working abilities and fiery attitude, she manages to climb up the ranks in the company (under the devious scheme of a certain CEO) and even gains a fan girl who can’t wait to be her sister-in-law.

As Pei Ge navigates through the ups and downs of office politics, family drama, finding her right partner and societal expectations, she realizes that things are not as simple as it seemed and everything she had believed in is tested…

A gush of clear wind, half a full moon, the peach tree remains unchanging.

…

Wait, whose kid is this?! Why is she calling me papa? Gazing at the little girl in front of him with skin as pale as jade, Chen Xi froze.

…

　
Returning home from cultivation, starting as a stay-at-home dad.

In this life, not fighting to be a king nor claiming to be a tyrant, only praying to peacefully be a wife-pampering mad devil and a child-protecting daddy!
