About laughing at the safe.

The four-digit password corresponds to four snooping rooms, namely, the number of books not put in the bookshelf, the number of pumpkins, the number of apples and canned apples, and the number of chairs. Remember them after calculation, and then enter them in order. Make sure the four numbers are in the right place.

Please pay attention to the study room, as long as it is not in the cupboard, including the one next to the cupboard and above the cupboard.

In the pumpkin head room, observe for a while, and the pumpkin will disappear.

Apples+canned apples, the room is relatively large, so don't miss it by watching it several times.

There's nothing to say in the chair room.

Spy crash BUG is a common BUG in several Chinese versions of ISO. You can try downloading a new ISO, and then go to the video game Bus or CNGBA, where the version won't crash.

However, I personally suggest that you don't do it if you collapse. Spy missions are only about floats. There is no need to touch it. As long as you make a small flower car, you can get through the plot.
