Lin Yi dressed up as a Japanese otaku and woke up to find that he was surrounded by "old acquaintances"—— Seeing familiar faces doing unfamiliar things, he almost spit out nosebleeds. I wanted to keep a low profile, but I couldn't hide my talent in swordsmanship. One blow to defeat the senior's bamboo sword, two swords to defeat an invincible opponent, three swords... Wait, why are these women looking at me more and more wrong? Until that day, a woman named Kamiya Rin knocked on his door covered in blood: "Save me, and I'll tell you what secret the knife in your hand hides." From then on, the night in Tokyo was no longer peaceful. Shinto Wu Nianliu, Shadow Blade Organization, Yeyue Assassin... Each force focused on the three ancient knives on his waist. And behind him, there were also women who were willing to draw their swords for him. "Want to touch him? Ask me about my knife first." Time travel + swordsmanship + character contrast + multiple heroines
