[System + Invincible from the Start + Unstoppable + Building a Faction + Ruthless and Decisive + (There may be a little depiction of the hardships ordinary people faced in a feudal society. Skip those two chapters if that bothers you.)]

After Wang Zhong transmigrated into a cultivation world, he displayed extraordinary talent from a young age, possessing a Heavenly Spirit Root, Supreme Dao Bones, and a Chaos Sword Body. His future seemed bright, and he looked forward to relying on his talent and hard work in this life to reach the pinnacle and experience life among the elite. But just as he began his cultivation, his treasures made him the target of envy. A powerful clan of nobility used its immense influence to forcibly take everything from him. To curry favor with the powerful and cover things up, his own family cast him into the bottomless Demon Abyss. They never expected him to obtain the Defy Fate System. From then on, he began his bloody path to taking control of the cultivation world.
