Every martial arts prodigy has a dramatic origin story, but absolutely none of them are as hilariously agonizing as Ryu-Yeon's. Orphaned, alone, and looking for a path forward, our silver-tongued protagonist stumbles upon an enigmatic master of a legendary, long-lost martial art. The catch? To master the devastating lightning knives, Ryu-Yeon doesn't start with epic swordplay or deep meditation. Instead, he is subjected to years of grueling, borderline sadistic household chores.

We are talking endless mountains of laundry, gourmet cooking duties, and playing classical instruments under the guise of secret training. His master is a certified eccentric, but Ryu-Yeon is no pushover either. Armed with a massive ego, a sharp mouth, and a surprisingly high tolerance for suffering, he must endure this bizarre apprenticeship without losing his mind.

Lightning Degree perfectly balances laugh-out-loud comedy with jaw-dropping, high-stakes action. Watch Ryu-Yeon grow from a chore-ridden apprentice into a terrifyingly powerful master of the blade. As his journey takes him into the wider, chaotic world of the Murim, his unique skills and massive attitude are bound to shake the martial arts society to its very core. Will he survive the training and claim his place at the top, or will his own pride be his downfall? Strap in for an unforgettable adventure filled with epic battles, absurd training arcs, and top-tier banter.
