Night's Nomenclature Qidian
Hello, I'm here reccomending Night's Nomenclature because, first, it's already been recommended before (Here), and second, it's a cool futuristic transmigration novel where the MC works for his power (training arc---GO!)
Also, to my understanding, the protagonist is not a nice guy. And sticks to this personality throughout the story. If you like serial transmigration mcs that get stronger and stronger and actually have to work for it, then translate this!
