Thin Tiger Knife

That year, Song Ke was a useless person - his Dantian was useless, and the door of martial arts was tightly closed to him. That year, Song Ke won applause from all over the world and was known as Slender Tiger by everyone in the world. That year, Song Ke carried a rusty knife and entered the imperial city alone. The city was full of armor, but no one dared to stop him. That year, Song Ke was old and gray-haired, but he cut the sky upside down with one sword. When the truth doesn't make sense, pick up the knife!
