The whole school transmigrated, and by the time they met again, everyone had become a major power in their own faction.
After transforming, her luck changed for the better. She was taken home by a young lady from a sect and kept by her side.
She had thought it was just an ordinary little sect, never realizing that the pinnacle of the martial world had long been right there.
To find a way home and help the young lady of the sect fully resolve her meridian problem, they set off on their journey through the martial world.
But they discovered that the plague that made people throughout the martial world tremble with fear had actually been brought by the transmigrators...
"What? To the people here, vaccines are a plague?"
P.S. No angst, very sweet, and the female lead is only nice to the protagonist. Tsundere.
