The Day I Raised a Divine Beast in Another World

This lunatic like me actually traveled through time. Good guy, not only that, this world is also a world where sacred beasts are raised. This... I can't raise a few legendary beasts to show to those mortals. And I also have an ancestral system. Isn't this the peak of my life in one fell swoop? Wait, why do I say it is an ancestral system? Forget it, don't worry about these trivial things... Look there is a lone abyssal beast there, fuck her! What a good guy, he's pretty good-looking, so just keep it...
