I Have Bound the Survival Mission System to Doomsday Wasteland

"The first rule of survival in the wasteland: don't believe the 'random rewards' in the system prompts - last time I killed three lord-level iron-backed bears for a 'mutated beast cub' card; last time, in order to avoid the penalty of 'deducting 50% of supplies', I crawled all night in the radiation zone to find a purification device. But who can refuse a 'space warehouse'? Who can refuse the 'Thunderstorm Technique'? Who can refuse... When I rescued Su Wanyue, she gave me half a chocolate with red eyes - it was the last batch of stock before the disaster. Until the system suddenly issued the ultimate mission: 'Reshape the Law of Survival'. I just discovered that the so-called 'Gray Mist Catastrophe' is a situation, the so-called 'Mission System' is a knife, and I am just the one chosen by the Lord of Gray Mist... To wield the sword.
