Night had fallen when Qin Muye and 'Gong Kang' managed to infiltrate Prince's estate with ease, thanks to Qin Muye's financial prowess. The two were not assigned to any arduous tasks. Instead, they ended up helping in the kitchen, which basically meant slacking off.
Qin Muye had, after all, handed over some silver, unlike those who came to work for pay. The housekeeper who arranged for their entrance was quite honest and merely asked them to pretend to work.
When the time came, the two were each to carry a plate of cold dishes upstairs, and as long as they did not make a mistake, they would basically get a glimpse of the goings-on.
This was quite ideal, meeting all their requirements.
On the side, 'Gong Kang' was feeling somewhat frustrated. To him, the estate's security was tight, not easily breached by ordinary folk. But after he saw Qin Muye slip a small bag of silver to one of the housekeepers, the so-called tight security vanished, and they had easily slipped in.
