Dressed as a Vicious Male Supporting Character in a Fairy Tale

Qing Han traveled through time! After living for such a long time and usually having bad luck, how come it's like winning the lottery and traveling through time? And a system was also given away! If someone like him can have a golden finger, wouldn't it be possible to have a system for everyone? After coming back to his senses, Qing Han was about to take the system into the world, but he found out that he was the vicious male partner of a bloody novel, and he was also a cannon fodder who appeared in less than ten chapters!
