How Much Do You Know About the Song Dynasty? The Mechanical Maniac

When mechanical fanatic Lu Tianqi was teasing his self-developed AI, “Deep Think,” he was swept into the bloody twilight of the fifth year of Baoyou in the Southern Song. His soul entered the body of Lu You's great-grandson, making him a lone, courageous top scholar whom Jia Sidao had exiled to Diaoyu Fortress to die. He uses repeating crossbows to crush the Mongol army and fights them in a bloody battle beneath Diaoyu Fortress. But by sheer coincidence, he lets Mongke escape with his life, changing history beyond recognition.
