Interstellar Martial Arts Crash the Wizarding World

A high-ranking martial artist from an interstellar martial society died in battle on an interstellar battlefield, only to inexplicably find his soul transported into the body of a medieval noble's son. But this world seemed different from the Middle Ages he knew... Breathing techniques and battle aura: the medieval knights, who resembled martial artists, called this supernatural power system the Knight's Way. With the power to cleave iron and split stone, and strength weighing a thousand jun, nobles used the knights' supernatural might to rule the mortal realm and passed down their family glory through their bloodlines. Could it really endure unchanged for ten thousand generations? Matthew didn't care about any of that. He quietly built up his strength and practiced the Knight's Way. Faced with the unknowns of an unfamiliar world, all he wanted was to regain his strength as soon as possible and find a little sense of security. Yet as time passed and he experienced more, Matthew gradually discovered the truth behind this world... Wizards? After experiencing countless things in this world, Matthew reached a conclusion: “Wizards are utterly rational, selfish, and self-centered. Everything they do serves some purpose!”
