The address Lin Lei left on the note is... the summit of Wuji Peak.
Wuji Peak is the highest peak of the Wuji Mountain Range on Forest Island. It is an extinct volcano located in the southeast of Forest Island, adjacent to the sea and bordering the mountain range of the Underground City.
In fact, the Wuji Mountain Range is a large mountain range that connects parts of Forest Island, the Underground City, and King Island. Previously, the Underground City was concealed by formations, unknown to the world.
"Why hasn't the fire in the Underground City started yet?"
When arriving at the foot of Wuji Peak, Long Qian looked towards the Underground City and wondered out loud.
