When the names of quantum physicist Gu Linyuan and explosives expert Jiang Jin were entered side by side into the "Myriad Illusions Labyrinth"...
The System announced in a cold, mechanical voice: Coexist, or die together.
In a rule-based horror instance, Gu Linyuan deduced the time difference between mirrored images, while Jiang Jin's blade shattered every illusory reflection;
In a molten, ruined city, Jiang Jin blasted open a path, while Gu Linyuan instantly calculated the optimal solution for the cooling core;
In a star-track prison, their consciousnesses were trapped in a virtual universe by a chip. Jiang Jin went berserk and blew up the control center, while Gu Linyuan rewrote the ultimate code three seconds before the explosion: "If you dare to die, I'll rebuild the entire System."

He would always leave his back to him, and his flames would always hold back their softest warmth for him.
