The protagonist of this book is no righteous hero. To survive and grow stronger, he can abandon everything. To achieve his goals, he will stop at nothing, even committing evil. You could say this is a book about a villain.
"I swear." Ye Wuxie suddenly turned around and looked out the window at the sky covering the earth, then shouted with all his might at the sun that illuminated all things.
"I will become stronger. No matter what means or methods I have to use, I will become stronger. I will devour every weakling I can, and use every way I can to grow stronger. Even if I have to fall into evil and become a demon, even if I have to become an ugly beast, I won't hesitate."
"I will become stronger. I will survive. I will struggle to stay alive in this world. I will live. I will live my own life, and make it entirely my own."
"Heaven and earth, bear witness!"
