Completing the achievement of collecting all containment objects in the Seven Day World requires players to collect how many containment objects? This is certainly a question that many collectors are puzzled about. Since the containment objects have the ability to hatch on their own, players can actually unlock the full encyclopedia achievement by just collecting the initial creatures during the collection process. In this article, I will specifically analyze the strategy for completing the full encyclopedia achievement, hoping that this content can help everyone~

The game's containment objects are categorized into five-star, four-star, and three-star levels. The five-star containment objects represent the Space Cube, Element Boy, Giant Mushroom, Deadly Bunny, Master Hand, Azure Dragon, and Active Gel. These creatures have relatively strict production requirements. For example, the Space Cube can only be obtained with a certain probability after multiple teleportations, while the Element Boy requires the player to enter a mine and obtain it during mining. The Giant Mushroom needs the player to plant crops, from which it can be obtained with a certain probability during the growing period. Overall, five-star containment objects can only be obtained through a large amount of collection and gathering with a certain probability.

In comparison, the acquisition difficulty of four-star containment objects is lower. They include the Withering Seed, Box Lighter, Obedient Rabbit, Child of the Sky, and Snow Globe. Players can directly obtain these containment objects by opening treasure chests in the world. For instance, the Withering Seed can be purchased directly from the farm merchant, while the Obedient Rabbit is located in the southeastern part of the forest area, and players will definitely find this containment object in the treasure chest there.

Three-star containment objects include the Frost Jellyfish, Black Cat, Mini Yellow Coat, Little Paper Man, Alien Dimension Big Cat, Paper Man, and Moon Cat. These creatures appear in the game world, and players can obtain them directly by hunting. For example, the Moon Cat can be hunted in the forest during a full moon night. Overall, the acquisition difficulty of three-star containment objects is the lowest.

The above content is the complete introduction to the Seven Day World containment object encyclopedia brought to you in this article. Containment objects must be placed in independent containment units to charge with abnormal energy, and their activity level also affects their state. I hope that after reading this content, everyone can go into the game and experience it directly~
