While obeying his master's orders to annul his engagement, An Buran awakened memories of his past life. He had transmigrated to a fantasy world of immortals and heroes, becoming a major villain! He possessed double pupils and a cousin with immortal bones, whom his mother might one day bring to him. He was inherently cold and indifferent to everyone, especially his sister An Buran, whom he treated harshly, beating and scolding her mercilessly!

A pure egoist, he would stop at nothing for resources, even harming his own senior sister, causing her to lose her position as the chief disciple. ...In despair, he fortunately awakened a system. To pull back from the brink and survive, An Buran decided to fight against fate!
