He closed the door, refusing to step outside.
Since he had set a stakeout to wait for the thief, it was crucial not to alert the prey.
He had to act as normal as he did on any other day.
Eat when he should eat, drink when he should drink, sleep when he should sleep.
Of course, the sleeping mentioned here didn't mean for Yang Xiao to actually sleep, but to feign sleep.
If he really fell asleep, who would catch the thief?
However, it was still early, and while Yang Xiao could have taken the opportunity to sleep for a while, he found himself not the least bit sleepy, even though he had done a lot that day.
Ever since he swore allegiance to a reclusive expert, Yang Xiao's abilities had improved significantly in every respect.
