Nightblade, a former tactical expert in an international special forces unit, is on the verge of death after a helicopter crash when he's chosen by the mysterious “Abyssal Corridor” and thrust into the “Eternal Night Trials,” a journey across countless heavens. This is a “world furnace” created by a higher civilization. Reincarnators are all test subjects meant to catalyze the evolution of worlds. The only way out is to complete 100 crossings or break the rules.
Rejecting teams and distrusting the System, Nightblade travels the myriad worlds as a lone wolf: cracking the virus code in a zombie-besieged Raccoon City, resisting mental collapse in the depths of a Cthulhu-like ocean, wielding a heavy iron sword in a martial arts world, upending the compass of fate on a battlefield of immortals and demons, hunting AI cores beneath cyberpunk neon, and evading fate's lock in a frozen apocalypse...
The “Fate-Reversing Mark” on his left arm evolves from analyzing rules to transcending dimensions. The “Chaos Core” in his palm evolves from fusing energy to controlling causality. The shadow storage case at his side holds trump cards from countless worlds. Hunted by the “Enforcers” controlled by the Corridor, and courted and watched warily by the resistance group “Wallbreakers,” he uncovers the scheme of the entropy-increasing civilization behind the “Watchers.” The Corridor's ultimate purpose is to select “World Devourers” and use the energy of countless worlds to delay its own demise.
After 2,000 battles for survival and the collision of civilizations across 100 worlds, Nightblade struggles between the power to “devour worlds” and his conscience, which urges him to “save all living beings.” When the core of the Abyssal Corridor opens and the true form of the entropy-increasing civilization is revealed, he will face fate with his solitary blade: either become the new ruler or destroy this cage and set every world free. The lone wolf's path has always led only in the direction he chooses.
