Birth of the Black Dragon

Millions of years ago, humans fought with gigantic monsters. Not just on this planet, but everywhere in the universe. They fought on millions of planets. These monsters were not only strong, but intelligent. The stronger monsters even gained a human form. Dragons, phoenixes and other legendary monsters were capable of destroying countries. Their strength was immeasurable, their defense was impenetrable. Nukes and missiles were useless. Science was useless. In these times, humans abandoned their beliefs and turned towards things like magic and spiritual powers. They started studying monsters and learned millions of new things as a result. The most effective weapon turned out to be the human body. The potential was limitless and soon humanity created the first ancient martial art. This ancient martial art was created based on the whole new type of knowledge obtained from monsters. Soon, humans appeared with unimaginable lifespans and strength. This change started a war.

Only sadness, anger, regret remains. Nowadays, humans and monsters are living together in harmony and peace. ... My name is Ryan Black. I'm fat and lazy. My family is poor.
