I Became the Only Tyrant in the All-Female Healing Class

[Urban Magic] + [Harem] + [Decisive Killing] + [Thought Control] + [Super Complete Combat System] Jiang Yigang awakened the Pseudo-Magical Healing System after traveling 300 years ago. When he thought he would be a useless person and could only rely on his brothers and the school belle to make ends meet, he unexpectedly awakened the [Barbarian Tyrant] system during an attack! From then on, there was the cool and cold school beauty in the school, my charming wife-like boss, the hot short-haired big sister, the sunny and lively girl, the short-haired lolita with twin tails... While others were still struggling in the hands of the monster, Jiang Yi punched the monster's head with his physical body. "Why is his body so strong?" "Sorry, your magic is no match for me!" Jiang Yi gradually developed his power and became the supreme barbaric tyrant in the magical world. Countless surrenderers knelt down and kowtowed, shouting: "The soldiers are in ambush, kneel down and worship my lord!!!"
