Old Warehouse
Lin Mu did not move his short sword from the neck of the masked man, even after he declared his surrender. He did not want the man to surprise him after letting his guard down.
Lin Mu instead scanned every inch of the man's body for any hidden weapons or dangerous items. He had seen the darkly dressed men use poisons, thus he wanted to be extremely sure of his safety. After scanning the man with his spirit sense, Lin Mu found a few weapons hidden on his body.
This included four daggers, one each hidden at the ankles and wrists along with a set of metal needles which seemed to be steeped in some kind of black liquid; most likely to be poison. Lin Mu took away all of these weapons from the masked man before allowing him to sit up.
"Now speak, who are you from, and why have you been following me?" Lin Mu questioned with a stern tone.
The masked man seemed to hesitate a bit before speaking,
"I am but my lord's tool and I was ordered by him to observe you."
