Quick Transmigration: The Years I Refused to Be the White Moonlight

[Two male leads / One-on-one romance / Quick transmigration / Lighthearted, no angst]

Shen Jingzhi was an outstanding employee in the White Moonlight Department, ranking first in performance year after year. After an accident, he was transferred to the Cannon Fodder Division.

But after several cannon-fodder missions, Shen Jingzhi was targeted by an unknown mastermind. Every world collapsed and bugs began appearing everywhere, so he had no choice but to go back and repair them...

World One: In the interstellar era, he is the chief researcher at an institute, and the general's husband in a sham marriage where they are at odds even in bed. After the general is reborn, Shen Jingzhi expects him to take revenge, but instead the general tears up the script and insists on turning their story into one of love after marriage...

World Two: In a cultivation world, he is the villainous master of a destined hero. He casts the protagonist out of his sect, and expects that the protagonist, now ruler of the demon realm, will lock him in a dungeon. Instead, when the protagonist returns, he locks Shen Jingzhi in his bedchamber... (The System will pretend to be his son.)

World Three: He is the sickly older brother in a story about a broken engagement. When his younger sister runs away from her wedding, he cruelly bullies her fiancé, only to be carried straight into a haunted old mansion and made to follow household rules laid down by his former would-be brother-in-law...

World Four: He is a disabled older man who keeps a pretty young companion. After the companion is reborn, he vows to bring him down, but when poverty leaves him destitute, he discovers his teammate in the arms of the older man, whose face is cold and beautiful...

World Five: He is a cannon-fodder character who dies early in a world of horrors. To complete his mission, he has to snatch a psychopath's chainsaw and chase him for three days and three nights...

World Six: He is a cannon-fodder doctor in a domineering CEO novel. When the CEO coughs, he pulls out a bottle of laxatives...

World Seven: He returns to a mission world, only to find that he has long since turned to ashes. All he can do is float beside the protagonist and curse at him every day...

There are lots of settings, and the order may vary.
