My Technique Changes Every Day

Qingshui Weiming is a transmigrator, and an unlucky one at that: the System mistakenly bound him to itself. The System's remaining energy had to be used to find its destined Host, so it couldn't send Qingshui Weiming back to his original world. Qingshui Weiming took it well. He wasn't going to live much longer in his original world anyway, so he figured he'd gotten an extra life for free. The System was touched by his understanding and, before leaving, spent its own resources to give him a cheat ability: A card pool that lets him draw once a day... Since the System automatically adjusted his body to suit this world's constitution, Qingshui Weiming's cheat ability turned into... A random technique that changes every day. The possibilities include, but aren't limited to, making flowers bloom, leaving his body as a spirit, cross-dressing... and even cooking? Qingshui Weiming: "That last one is ridiculous!" 1. Mainly Jujutsu Kaisen, protagonist is the top, pairing undecided. 2. Anything can come out of the card pool. It draws automatically at midnight each day, and then turns into a technique's effect. 3. The protagonist's technique is called [Shapeshifting]. It was inspired by Martin Morning (does this give away my age?). 4. More to be added. Theme: You never know whether tomorrow or an accident will come first.
