Sorry, I'm an Assassin

In the farmland of Lu'an Town, "Are you Chen Ning, the abandoned disciple of Tianxing?" "I'm Chen Asi, no, not some abandoned disciple of the Star, Chen Ning?" But the tone and the slight frown betrayed him, and suddenly a sword was placed on his neck. Chen Asi then said nervously: "Young hero, what do you want to do? Have you recognized the wrong person? I am really not Chen Ning, the Tianxing Sword, am I?". But the man was minding his own business and started to say: "Chen Ning, the Tianxing Sword, killed the master, stole the top secrets in the sect and disappeared." Chen Asi explained angrily: "This is a slander. I didn't kill my master at all, and I didn't steal any secret books..." He was then killed with a sword. "I know, but I'm sorry, I'm an assassin."
