On the third day, I explained in detail how to get the chessboard key.

Raiders on the third day: First, players take the needles and photos in the right drawer and flowerpot respectively, and then press the above picture under the sand to get the key.

Second, put the obtained needle into the first lock and click it in the order of 4 132.

Third, fill in the words that the player saw from the cat's eye on the table and spell out the shape of the key.

4. Open the door with the key you got before, get the badge in the lower left corner of 004, and then get the wooden handle of the cabinet and the radio adjustment diagram.

5. Put the wooden handle on the god of wealth tree, then open the mechanism in the hole below, manually change it into gold coins, then pull it down and click the handle to get copper coins.

Music: Arrange the coins in Room 004 in the order seen in Room 003, then enter 005 to talk to the old man and get the tape from the guitar.

7. Enter 002, put the tape into the radio, and adjust the tone channels of red 30, yellow 60 and blue 90.

Poetry: Turn 004' s cash cow into dollars, and then give the money to 005' s old man to get the lock opener and go to 004 to open the safe.

9. Memories: Put the badge in the groove, get the photo with 002 poker, and then put the tape, book and photo on the balance in 004.

The diode obtained in 2005 was placed on the clock in 2004.
