Douluo: What Does the Silver Dragon King Know About Spirit Beasts?

The Silver Dragon King! Has she ever been a spirit beast? Some things are written haphazardly, taken for granted. She's just a premature dragon, a creature who never even learned early education. This Immortal Dragon Girl, who fancies herself as having inherited the Dragon God's wisdom, does nothing but stab the already dead spirit beast race a few more times. She even uses her tens of thousands of years old body to devour the twenty-something tender grass, Tang Wulin! This can't even be described as premature anymore. Silver Dragon King, get out of the way! Today, I, King Rus, will teach you how to revitalize the fate of the spirit beast race! Watch my moves. The protagonist starts as King Rus from Seer, and the system grants him a continent, but he has to play a coloring game step by step. Later, the protagonist will evolve into Blade King Rus, Lord of Blades King Rus, Starlight King Rus, and can switch between forms. Note: Since he is King Rus, his harem consists of dragons, spirit beasts, and system races' elites...
