Xinhun Zhang Men Gao Jijian

The soul goes to another world and becomes a female head... Wait! As a man stuck in a woman's body, I need to marry a cold-blooded murderer for the sake of the sect? The pit the father of the body has dug for me, I'll use my 250 IQ to get myself out! Science and technology to strengthen my group, infrastructure to strengthen my sect, and advanced concepts to create the strongest martial arts!
