Dr. Delong's notebook at Adventure Island.

After completing the password authentication task, enter the unknown underground passage connecting the two. There is a manhole on the right wall on the second floor, which is the place to enter the institute. After I go in, I will study how to go by myself, because I can't say clearly ... When I get there, I will point the magic circle to the middle in the order of up, left, right and middle. Finally, I went back to the ice rink and asked Alcatel to hand in the task.
