International mercenary Gu Changqing disappeared on the battlefield and fell into the "infinite corridor" that swallowed a billion creatures. The dungeons here are execution grounds—medieval castles, cyber wastelands, Cthulhu Abyss... The losers turn into a series of obliterated numbers on the statistics screen. Being accustomed to walking alone, he rescued the pale and sick Lin Yan among the mechanical beasts. This person is weak in terms of force, but he repeatedly breaks through deadly situations with his top-notch IQ.
The two male protagonists form a deadly combination: Gu Changqing clears the way with his blade, and Lin Yan steers the ship with his resourcefulness. When Lin Yan died protecting Gu Changqing in the final copy, the cold system revealed the truth: In this game, only the winner can control the creation key. Lin Yan gave "absolute rationality" to Gu Changqing at the cost of his existence - "Take my brain to see all possibilities."
Gu Changqing inherited the dual SSS+ characteristics and swept the remaining copies with Zhanzhi. On the day he reached the summit, the system granted him the [Real Universe Key], announcing: "Your universe is waiting for you." The price was that Lin Yan had returned to nothingness... Until Gu Changqing stared at the key in his palm and noticed the dimensional coordinates left by Lin Yan. This time, the hand holding the knife will fight for creation - exchanging eternal loneliness for a reunion at the end of the Final Observer.
