If you could choose three of these seven things, what would you pick? 1. Thirty million in cash 2. Grow ten centimeters taller 3. +++ to your looks Modern college student Chen Zhiling had spent years immersed in the “pick three of seven” game. She never imagined that one day, one of the sets of seven she'd chosen would actually come true! Chen Zhiling was completely floored. Transmigrating to a future interstellar world was one thing, but how could this world have humans and supernatural creatures living together? What! Humans had been making pacts with supernatural pets for over three thousand years, living and fighting together? Even the technology of the interstellar age had been developed with the help of these pets? Fine! Chen Zhiling gritted her teeth and accepted the idea of beast taming. But if you're taming beasts, then what are mechs doing here? What kind of respectable family calls mechs mechanical-type pets? This world has way too many elements crammed into it! * To live a comfortable, carefree life in such a dangerous world, Chen Zhiling decided to stick firmly to the excellent strategy she'd followed in her previous life: aim for the middle! As long as she could get into a group of high-caliber people, some big shot would carry her to victory with ease. Unfortunately, her golden finger wouldn't let her! At the high school beast-taming league, Chen Zhiling looked around: a young prodigy to her left, an undefeated legend to her right, an heir to a great family in front of her, and a dark horse who'd risen from nowhere behind her. She hugged herself and her pet in terror. She had to play it safe for as many rounds as possible! After the competition, Chen Zhiling: Wait, you guys weren't all that good! At the military academy beast-taming tournament, Chen Zhiling felt incredibly safe among all those beast-taming geniuses. Hooray, she'd finally found big shots to carry her! Halfway through the tournament, Chen Zhiling returned alone after taking her pets out to find food for the whole team. Wait, why are you all lying down? On the real battlefield, facing mountains and plains full of mutated creatures, Chen Zhiling tried to calm her racing heart. It's fine, it's fine. She just had to follow the big shots and fight her way through! The comrades all around her gazed at Chen Zhiling and her pets with shining eyes. “Big shot, big shot! Take us with you!” Chen Zhiling: Damn it! I was at death's door, then sat bolt upright. I'm the big shot after all!!! Reading tips: 1. This story takes place in an imagined future. All the worldbuilding is made up by the author, so please don't compare it to reality. 2. Genius protagonist, beast-taming battles, competitions, military academy, and exploration. 3. The heroine grows over time. She's a little chuunibyou at first, likes thinking things over by herself, and sometimes ends up arguing with thin air.
