Demon Slayer: I Am the Master of Breathing Suturing!

Traveling through Demon Slayer and becoming cannon fodder for the final selection? Don't be afraid, I have a PhD in physics! While others are sweating and practicing water breathing, the [Breathing Technique Editor] in my mind has already completed the analysis. [Water Breathing, energy conversion rate is 17.8%, There are 32 power redundancies, which can be optimized! When Zenitsu could only use the Ikata, I had already stitched together the Breath of Thunder and the Breath of Sound, realized the [Thunder Breath and Railgun], and wound it in seconds with a single blow! Yanzhu: "Young man, why can your flames produce directional explosions?" Me: "This is called the second law of thermodynamics." Feng Zhu: "Kid, why can your wind blade track and turn?" Me: "Bernoulli's principle, just basic physics." When everyone was shocked by my stitching breathing method, I just smiled modestly. "It's nothing, just know some science." No misfortune? Don't worry, wait until I sew the Breath of the Sun with your Vampire Technique, and let you see what [Nuclear Explosion Breath] is!
