For an Explanation

Gu Ning, however, didn't think it was a big problem. This manor might be very dangerous, but she didn't think she would get hurt. Therefore, when the gatekeeper said that they could go in, Gu Ning didn't hesitate at all and walked inside.

The others did the same.

The two gatekeepers, on the other hand, felt they had too much confidence. Weren't they afraid that they wouldn't survive today?

One of them stayed to guard the gate, while the other guided them inside.

Along the way, Gu Ning used her Jade Eyes to check every corner of the manor.

This manor looked as normal as any other on the surface. All the people in it were very strong, but it didn't mean that they were all killers.

There weren't many people there; the number wouldn't exceed fifteen.

There were two guards at the gate of the manor, two at the gate of the main building, two in the backyard, and two in the room.
