The Siberian tiger needs the following three important living conditions to survive: sufficient food, sufficient water and dense forest or grass. Although the living conditions are harsh, illegal hunting or poaching is the top reason that places the Siberian tiger in desperation. The creature is now listed by the International Union for Conservation of Nature (IUCN) as an endangered species. A group of criminals from the future world came to the present-day city in search of a hidden treasure in the forest. To enable a smoother operation, they killed a large number of Siberian tigers living in the forest and Solar Junior was unfortunately involved in the quest. What could be the treasure that the criminals were looking for?
