Demon Slayer: the Road to Slaying Ghosts Starting from Miyamoto's Template

(In chapter 40, the main character does not have to suppress his combat power. He slashes out a 3-meter-high sword with a width of 1 person + fighting is exciting + changing his destiny + kicking the box lunch + upgrading flow before chapter 62 and invincible flow after chapter 62 + multiple illustrations to give a strong sense of substitution) What will happen when a poor-quality massage chair leaks electricity and knocks Uesugi Souji into the world of Demon Slayer while watching a Demon Slayer movie? I bumped into Hiro Kai at the beginning. Is this the rhythm of delivering food to a ghost? Just after he fell on the dark and deserted mountain, before Souji Uesugi could even curse, the muffled sound of ghost drums came from the thick fog, and the green-faced and fanged Xiangkai came out of the fog. Uesugi Souji's legs went weak on the spot: "Someone else started by traveling through Tenhu, and I started delivering food to Oni? Is this reasonable?!" On the line between life and death, he grabbed the sword at his waist randomly, and the next second a mechanical sound exploded in his mind: Miyamoto Musashi's template was successfully bound, and the second-tier class was passively activated. The protagonist, a time traveler, has a non-European emperor's physique, and relies on templates and breathing techniques to defeat evil spirits.
