Quick Travel: the Poor Little Cannon Fodder Is Always Bullied by the Protagonist

"Binded to the 'cannon fodder system', Zhang Yuan's mission is to go to various small worlds to play the role of miserable cannon fodder. The first world is Bate's despised wife in the ABO world. It is obviously a toy that is disliked by the protagonist Gong and used to kill time and have fun, but why does the protagonist Gong find another way to bully the little cannon fodder? The second world, the disabled dog orc in the world of orcs. Because he was born with a disability, unable to hear, and not good-looking, he was disliked by the tribe. The cannon fodder who should have been kicked out in winter was forced to stay by the protagonists. The third world is a low-class servant in the prince's palace in ancient times. I used to live a life of being beaten, scolded and not fed enough every day, so my underwear began to disappear frequently.
