Demon Slayer: I Reach the Summit with Thunder Breathing!

Luo Ru transmigrated, and from the start, Muzan tore his parents to pieces. Crack! Suddenly, thunder boomed out of nowhere in the night. The whole building collapsed with a crash. Luo Ru survived by sheer luck. At the same time, he gained the ability to distill each day he had lived and use it to strengthen himself! He could extract everything he gained each day! And there was no limit! He decided he would stay hidden until he was strong enough before stepping out into the world! And so... Hand Demon: “Is this really the kind of strength a trial candidate should have?” Douma: “So this is what pain feels like... I really want to feel it again...” Kokushibo: “Can Thunder Breathing really be this powerful?” Muzan: “Fine, I’ll wait you out for a few hundred more years!” This is the story of someone who masters Thunder Breathing and slays Muzan.
