The old man was from this town, so he naturally knew that there was a clinic there. Although he was quite suspicious, he still held the fool's hand and followed the spy into the alley.
When there was no one else, the spy rolled up the fool's left sleeve and saw that there was really a mark of a secret guard on his arm. This was definitely the secret guard from back then. He immediately knocked the fool unconscious.
"What are you doing?"
The old man questioned loudly in panic, but before he could say anything, the spy drew a knife and pressed it against his neck. He asked, "Is this fool really your son?"
Without waiting for the old man to speak, the eyes of the spy turned vicious. "If you don't tell me the truth, I'll kill you now!" As he spoke, the blade pressed against the old man's neck.
The old man's neck was a little cut, and a little blood seeped out.
