The Demon King Turned into a Flea, and the School Beauty Was Sucked into Me and Turned into a Martial Emperor

When he woke up, Qin Shou, the demon lord of the demon sect, found that he had turned into a flea, a female one! What's even more terrible is that with only three hours left to live, the only way to survive is to drink blood! The system of becoming stronger by sucking blood has been bound. Host: Qin Shou (former Demon Lord). Current form: harmless little flea for humans and animals. Mission: Draw the first sip of blood, reward: Novice gift package (extended life span + breakthrough in cultivation) However, the target he was eyeing was the school beauty Shen Xiaoqian who had a Xuanyin physique—— Her blood not only allows him to survive, but is also an excellent tonic for a surge in cultivation! What's even more amazing is that during the blood-sucking process, he actually fed back a trace of the Demon Lord's spiritual power to her, turning her into a warrior overnight! "Suck a drop of your blood to help you become a warrior! In this deal, you earn with your blood, and I, the old flea, don't lose either!" See how a generation of demon king regains his glory in the form of a flea, and helps the school beauty to counterattack and become a martial arts genius!
