Alternate History: I Awakened the Poisonous Strategist System from the Start

After an inexplicable transmigration, Yang Yi unexpectedly awakens the mysterious Poison Strategist System.

At the time, the empress says gravely, “The enemy kingdom has been destroyed, but there is only one seven-year-old child left in the palace. I cannot bring myself to kill her, for my heart is too soft. What would be the proper way to deal with this?”

Yang Yi's eyes dart about as an idea strikes him. He hurries forward and reports, “Your Majesty, in my humble opinion, this child dared to show herself because someone must be secretly protecting her. Your Majesty could pretend to let her go, then quietly return and carefully investigate whether she has any younger brothers or sisters hidden in the secret passages. If you find any, make sure to wipe them all out. Then build a tomb in their name and assign someone to pretend to mourn them for three years. Anyone who comes to pay their respects during that time must be one of their accomplices, so you can eliminate them as well and nip future trouble in the bud.”
