A Sashimi Knife to Dominate the Entire Academy

I was once the strongest swordsman in the country. I have held swords for twenty years and my swordsmanship is superb. Until one day, I entered the mobile game "Miracle Asylum" that I had paid for several times—— Not dressed as a player, not dressed as an NPC, but dressed as a background passerby who didn't even have any lines. What's even more outrageous is that the conditions for activation of the "Sword God's Protection" I awakened are outrageously harsh: The length of the sword is less than 30cm, and the width of the sword is less than 5cm. This size... Isn't it just a sashimi knife? So, the Joaquin College placement test was taken. When those noble children appeared on the stage carrying handed down swords and epic staffs, I, a special admissions student, took out a sashimi knife from my bag that I bought at a discount in the supermarket. The instructor broke his guard on the spot: "Is it reasonable to bring a sashimi knife to the placement test?" I responded calmly: "Only the weak care about the quality of equipment, and I never choose equipment." Then I pulled out the knife. Sword God's Protection: Break with a swing of the sword - activated. The space is broken. Humanity's strongest "Sword Emperor" pursues the highest realm of swords all his life. Saw it on a special admissions student holding a sashimi knife. In just one minute a day, I became a sword master with a sashimi sword.
