Calamity of National Destiny: My Calamity Demon Bear Becomes the Savior

I'm Zhang Xuan. I've spent decades in a disaster zone, and I've become a regional BOSS, a disaster bear. I've spent decades muddling through this world without ever seeing a living person. I thought I'd be alone like this forever, until one day... The intelligence System told me that invaders had appeared in the disaster world, and that they came from countries all across Blue Star? Our Dragon Nation is facing its final National Destiny game. When this game ends, the disaster world will descend upon us for good. The other countries' contestants are all adults with powerful classes. But our Dragon Nation's contestant is a little girl? Instead of choosing the SSS-rank Sword Immortal class, she picked a C-rank Beast Tamer. The whole world is laughing at us, saying Dragon Nation will be the first country to fall. But then something unexpected happened. When Lin Xiaowan appeared in the disaster world, a regional BOSS known as the Disaster White Bear doted on her to no end. While the other contestants were still dodging monsters, the magic bear was already leading her on a rampage across the world. While the other contestants carefully worked through their quests, she rode on the magic bear's head and charged straight ahead. The whole world was stunned. It's the same National Destiny game, so why does your contestant come with a BOSS-level babysitter? And this regional BOSS seems to be targeting the contestants from Sakura Nation and Eagle Nation in particular. This is already the ninth Sakura Nation contestant and the sixth Eagle Nation contestant to be killed by the regional BOSS. Sakura Nation is in tears: Please stop targeting us! Keep this up and our island will sink!
