I, the Ultimate Poisoner, the Empress Advises Me to Be Kind!

A hundred thousand troops besieged the city, and the capital was in danger! Empress: "Who can break this situation?" Chen Yin: "Digging up the ancestral graves of people's families and launching catapults onto the enemy's barracks caused a plague. This situation can be broken!" Empress: "... How did you come up with such a vicious plan?" Chen Yin: "Your Majesty, if you can't defeat them, you will have to move south. If you move south, you won't take the villain with you. The villain is afraid of death, so it's better to kill the enemy." Baiguan: "..." Is this guy really just a censor?
