In doomsday survival type games, many players find that containment objects, as special existences of supernatural power, can provide various aspects of assistance to players, from resource collection to combat resources, and so on. Therefore, players want to understand the overview of containment objects in the 7-day world. After all, if players can obtain these containment objects, their own strength will often be enhanced, but players also need to understand the functions of these containment objects.

Containment objects are also divided into different levels, and containment objects of different levels will have different types. Among them, the five-star containment objects:
The Colossal Mushroom can automatically plant crops and make them grow quickly, with a significantly increased probability of producing mutant crops. In fact, when players want to obtain it, they only need to plant mushrooms, let them mutate, or directly collect mushrooms in the wild and then trigger them.
The Space Cube can create portals on its own, allowing the entire team to move quickly. Players can obtain the Space Cube by completing side quests, such as rescue missions, which will result in it dropping.

Elemental Boy can automatically mine ores and has a certain probability of producing silver ore, and players can obtain Elemental Boy by mining tin ore.
Four-star containment objects:
Compliant Rabbit can gather shrubs, reducing resource pressure. Players can obtain Compliant Rabbit by chopping down Dragon Blood Trees with an axe, which will drop with a certain probability.

Electric Eel can increase the power generation of generators, solving energy shortages. Players can obtain Electric Eel by fishing directly by the seaside.
Portal Door builds two teleportation doors within the territory, optimizing map movement efficiency. Players usually obtain this through abnormal refreshes or by opening chests, with a certain probability of obtaining it.
Three-star containment objects:
Bee Cluster can effectively increase the mutation probability of crops, optimizing planting yields. To obtain it, players need to go to Dayton Wetlands and kill Mimic Chest Monsters.

Lumberjack Beaver can automatically cut down trees, and once obtained, it can effectively improve the efficiency of logging. To obtain Lumberjack Beaver, players can fish at the fishing dock or chop down large trees, which will drop it.
Rare containment objects:
The rare containment objects involved include Azure Dragon, which players can obtain through the hidden level of the Containment Well Fei, and also include the Nuclear Lighter, for which players need to successfully pass the Dark Prison Containment Well. The Voodoo Doll is obtained through refreshing at the Vulture Stronghold.

This is the end of the overview of containment objects in the 7-day world. In the game, containment objects are also classified according to star ratings. However, in order to effectively improve the efficiency of doomsday survival, players will try every means to obtain containment objects and also need to reasonably match their functions.
