As a rather challenging containment well instance in the Seven Day World, its complex mechanisms and high-intensity combat design often lead to frequent player failures. In the following, the editor has prepared a guide on how to tackle the Seven Day World's Cold Realm. The long-range suppression by snipers, temperature decay in the extremely cold environment, and the one-shot skills of the boss, the Fridge Monster, are all the key difficulties in clearing this containment well. Next, we will introduce how to make your dungeon runs more efficient.

At the start, descend vertically from the Lone Wolf Wasteland entrance, using a glider to avoid the dark-uniformed gunners patrolling on the ground. After reaching the second platform, quickly clear the two snipers in the northwest corner and seize the access card in the blue storage box. Weapon configuration should balance burst damage and shield-breaking: choose the Beyond the Door as the main weapon, paired with an ice attribute module, and carry the Ice Rain as a secondary weapon for breaking the ice layer covering the generator. For armor, use the Four Lone Wolf set, replacing the headgear with the Mayfly Goggles to enhance snow vision, and select the Elemental Manipulation Module for the legs to increase ice resistance.

The character level needs to be 45 or above. When facing the Fridge Monster, you must prioritize destroying the generators; two in normal difficulty and three in hard mode, otherwise, the boss will infinitely regenerate its shield. The speed of the long-range ice cones is relatively slow, allowing for early prediction; use cover wisely to dodge the boss’s ice cone attacks and keep moving to prevent being frozen. In team challenges, it is recommended to assign roles, such as having someone specifically to draw aggro or focus on DPS. In the laser trap area within the dungeon, proceed cautiously, slowly crouching to avoid triggering alarms. If immobilized by a drone's electric shock, teammates need to rescue promptly or clear nearby minions in advance.

After clearing, there is a chance to obtain rare rewards like Stardust Source Essence, Golden Lower Body Module, and Upper Realm Egg. For higher drop rates, try challenging hard or master difficulty, but ensure that the team works well together. Soloing requires a certain AOE capability. Also, do not neglect carrying supplies and cold-resistant items. Moreover, obtaining the Snow Globe Containment Object inside the dungeon depends on the number of times the infrared emitter is destroyed; it is suggested to trigger the alarm three times actively in the laser trap area to increase the drop rate by 23%.

The core loot of the Cold Realm instance lies in the stable production of Anomaly Immunity Modules. After each clear, reserve three portions of lean meat for unlocking the gene modification project of combat animals. When advancing to the laser trap area, triggering the alarm three times actively can activate a hidden refresh mechanism, which should help everyone complete the challenge more efficiently and gain rich rewards.
