The True Fantasy Dragon King of Death

It's really time travel! Lin Yu had ten thousand grass and mud horses galloping in his heart. With my level, why should I send them over to others for fun?

The system, of course, is in the heart, guiding the protagonist to grow and giving him power. I know you are here. Come out and don't be shy. "Come out." Lin Yu knelt on the ground and hammered the ground with both fists. There was nothing, of course there was nothing.
