Zhu Huanguang struggled to see, tried hard to see... but still could not make out the traces of the "newly made key" that Jiang Yuan mentioned.
However, looking at Jiang Yuan's expression, Zhu Huanguang knew that he might not really be bluffing him.
All Zhu Huanguang could do was shake his head, "This thief is a bit insincere, ain't he? Even a rabbit doesn't eat the grass around its burrow, and yet he could pick locks with a hook pick. He could beg anywhere, but he chooses to target someone he knows."
Jiang Yuan guessed and put down his phone, saying, "It's probably because he's a novice. He wasn't very skilled in committing his first murder, but he was cautious in character. So, he tried to make a key in advance, hoping to save time. The skill to make keys may also be newly acquired... either he's not proficient enough, or he was just unlucky. At the same time, he brought a hook pick just in case."
