Doing Homework in the Old Man's Innate Domain [Crossover]

[*About how I can take my exam papers with me as I transmigrate through dreams into different worlds, hoping to finish my homework, but keep getting caught up in all kinds of events (every student knows this pain) *The secret to never having overdue homework, something every dog-student (like the author) wants to know (not really) The day before registration, Yu Sang Sang is pulling an all-nighter to finish his homework when he watches the winter-break countdown hit zero. He has barely done any of his assignments... Yu Sang Sang: Eyes shaking.jpg He makes a snap decision. Gripping his paper, pen, and scratch sheets in his right hand and a stack of worksheets as tall as he is in his left, he swiftly gives himself a chop to the neck and passes out. The next second, he appears on a battlefield awash in blood and gore, homework in hand. Yu Sang Sang: "All right, time to get started on my homework!" (^з^) The next second, his head is gone. Sukuna: "...What just flashed past?" Yu Sang Sang stares expressionlessly at his untouched homework, runs to the kitchen, grabs a cleaver, and gives himself another chop to the neck. Anyone who gets in the way of me finishing my homework dies! ...Just before he gets killed in an instant again, he discovers that the other guy was speaking Japanese. Yu Sang Sang can't understand a word. But then he remembers how painfully poor his English is... Yu Sang Sang: "Can't I take Japanese exams now? Wait, I can do this!" Scenes to look forward to: --At last, Yu Sang Sang gets a good look at the guy who killed him twice. Tears and snot streaming, trembling all over, he drops his papers and, with a smack, clings to Sukuna's leg. "I've witnessed a miracle! You have four arms! You can do four assignments at once! Boss, teach me, teach me!" --As a certain white-haired cat coldly exorcises him, Yu Sang Sang yells, "You can kill me, but let me finish my homework first!" --Yu Sang Sang clings to Senju Tobirama's leg and wails, "Boss, please teach me Shadow Clone Jutsu! It's the ultimate homework-writing tool!!!" Theme: Study hard and keep improving every day
