This Lord is Very Scientific - Chapter 718 - 650

Gods choose those with natural talent; demons choose those who never give up.My name is Dylan Chen, a person chosen by the demons. Of course, you can also call me “Ghost Guest.” On the road of reincarnation, just mention my name, and the guards of the netherworld will make way for you.That day, I asked the heavens three questions, and the celestial beings and Buddhas remained silent. Then I knew there was no longer a place for me in this world. Therefore, I have no choice but to kill them all!Better to live a complete life as a mortal than to be an immortal for eons! This immortality, I shall not pursue!

#1 In a small town, young Daisy endures a life of suffering under the tyranny of her stepfamily and the neglect of her father. Her once loving home now a prison, she and her mother are forced to serve her father's new wife and daughters. When a proposal arrives from a wealthy but disfigured nobleman, her father, eager to protect his other daughters, condemns Daisy to a seemingly bleak fate.

Throughout this current life of mine, I will pay no attention to my past lives, nor will I seek future lives. I wish to live vigorously, to pay back debt of gratitude and fulfill duty to avenge, to defeat valiant heroes from all species, and to proudly laugh at all the Gods and Demons of the Six Path of Reincarnation!
