There are three kinds of maps of Heralu Castle. Being close to the castle will trigger the plot to become a blue 3D map, and it will become an orange channel map after entering the castle channel. The blue building structure represents the porter (most of them have treasure boxes), and the orange passage represents the secret door (it needs a bomb to explode). The big red core is the location of the main hall where Gainong is located. Not entering the main hall will not trigger a boss war.

The cookbook is on the second floor of the library, with a long table. At this time, having a lizard headdress is a happy thing. Don't forget to turn on the magnetic sensor. There are three secret doors in the library. One is the old king's room where you can peek at the king's diary (see the destruction of the kingdom of Hailaru), the other is the treasure chest, and the other is the one that leads to the dock and lights the torch to open the temple.
