I, the Tyrant, Will Make My Country Great Through Science and Technology

Qi Guang died in a sea of flames and transmigrated to another world along with his school's library, becoming a handsome tyrant. Everyone who saw him trembled in fear and hardly dared to breathe. Qi Guang: Even his own mother trembles like a sieve when she sees him. What kind of monster was the original owner? At first, Qi Guang thought he needed to change his tyrant persona. Even if he couldn't be a wise ruler, surely he could at least be a mediocre one who did neither great good nor great harm? But later he realized that being a tyrant was pretty useful. It suited him perfectly. Opium spreading everywhere? Kill the sellers, kill the transporters. Oh, the users don't value their lives and want to die? Then kill them all, too! Corrupt officials? An entire province full of them? Too many people, too wide a net, can't kill them? Sorry, there's no one this tyrant wouldn't dare kill! Note added on August 15, 2019
