Douluo's Divine Tribulation

Also known as "Douluo: The World-Destroying Demonic Dragon" Are gods really good people? Are they really just strong men who transcend levels? As gods, why do they have inheritance? What is the purpose of inheritance? Is it just to free themselves? The real purpose of the gods is very simple. They just want to occupy this world, because they are outsiders. Only by passing on time and time again will the world's suppression of them become weaker and weaker. "My purpose is very simple, just kill these so-called gods!"
