Koi Xiaoli received a special mission: to go down to earth, live with three sin-bearing beasts, and record observations.
The eldest brother Qingze, a cool and dignified man, is a famous garden designer, but he is always fascinated by a map late at night.
The second brother, Bai Lie, was hot-tempered and good at fighting. He ran the largest martial arts gym, but the scar on his left cheek burned and hurt in the deserted night.
The third brother, Xuan Mo, has a sleepy tongue and a venomous tongue, and is a master of Internet writing. His sleep talks contain prophecies that no one can understand.
Ah Li held a small notebook and carefully recorded: "My brothers were also very strange today, but... They were very nice to me."
What she didn't know was that on the day she arrived, three dusty case files were quietly reset, and a note from Yaochi emerged:
"Observer Koi Koi has been confirmed to be in place, and the plan has been implemented..."
The plan that had been dormant for thousands of years finally started to move...
Intention: Even if you are burdened with a heavy past, love and trust are still the most powerful weapons, and they can still transcend time and heal everything.
