Ever since Su Tian had transmigrated, she received a “Villainous Bosses Mentoring System” that could automatically identify villainous bosses IN THE MAKING.

As for her missions, they were a little more complicated. For example:

Stopping the boy in her class from deviating onto the path of becoming a villain;

Turn the boy who was going to create a global financial crisis into Jack Ma of the new world;

Talk the strange girl working at the toy shop out of her spending habit, because she will be the cause of hyperinflation!

And the boy from the countryside that she ran into, please give up on developing bioweapons! Why don’t you focus on the Nobel Prize instead?

“The education of love,” said the young man meaningfully!

Ten minute later, Su Tian… was educated.

System: This system is only responsible for identifying villains IN THE WORK. Matured villain are outside of its parameters.
