I Found a System in the Trash, and Contracted a Little Jingliu from the Start

[No heroine + multiple Systems + beast taming + urban setting + Honkai: Star Rail] [Friendly reminder: If you don't know much about Honkai: Star Rail, you can still enjoy this story.] Bai Ye transmigrates into the body of an 18-year-old vocational college student and awakens the “Beast-Taming Lottery” System from the start. Just like the protagonist of a game, every time you smash a trash can, you have a chance to obtain a new System! Choose from Systems that let you grow stronger by taking a beating, a tycoon System, a lottery System... You name it! With multiple Systems at his disposal, Bai Ye lets completely loose and soon becomes the greatest saint in Moyecheng! A beggar asks for money? He just snatches her metal bowl! A security guard blocks his way? He doesn't even bother arguing. He hands him a specially made “bomb cigarette” instead! And what does he do when he gets beaten up... Bai Ye smiles calmly and quietly pulls everyone in front of him! Genius senior: “I don't know what happened. I only saw him summon a beast-tamer named ‘Jingliu’ who froze me solid, then bombard me with ‘Oh-Po A5’ over and over!” The city lord's death squad: “I was just about to unleash a critical hit when he summoned a beast-tamer named March 7th and gave himself a ridiculously thick shield!” Secret-realm beast: “I've got it even worse!!!” “I was just taking a nap in the secret realm when he started yelling about bonds and friendship, summoned someone called ‘Firefly,’ and had her fire an Ultraman beam!” “She beat me into Hero Shards!!!” (Friendly reminder: The Honkai: Star Rail characters will act childish early on. Sorry if they're out of character. They'll grow into their in-game personalities later, though they'll still be dependent on the protagonist.)
