In a treehouse deep in the rainforest, Obstian, the secretary of the Halloween Chamber of Commerce, lived a long and peaceful life. Until an uninvited guest and a deliberate attack simultaneously tore apart the tranquility he relied on to survive. The two people who were forced to go together were surrounded by companions with different identities: members of the Chamber of Commerce with secrets, an island boy looking for his relatives, a rich young master who ran away from home, and three young Xiagu apprentices who were naive and ignorant of the world. The unsolved mystery forces people to form a team and target the ruins of the white dragon sleeping deep in the rain forest. However, what awaits them in the ruins is far from ancient treasures. The pursuit of mercenaries, the guidance of the mysterious girl, the deadly traps deep in the underground palace, and the dust-covered secrets that can shake the foundation of Ferma will all emerge one by one in this green shadow.
