Why not say something they'd like to hear?”Arthur took a deep breath and let out a deafening roar, “Oxford is a bunch of whores' bastards!”“Oh!!!!”The audience erupted into thunderous applause.“Cambridge is the same!” he added immediately.The applause grew even more fervent...(The protagonist, possessed by a devil, travels through 19th-century Britain in a world without magic)
