Earth was suddenly invaded by horrors from another dimension. Blood mist blotted out the sun, forcing humanity to retreat into underground dome cities.
Pei Xiao is the highest-ranking commander of the dome city, haunted by the childhood trauma of losing his parents to the blood mist.
Ghosts infest the surface, their forms ever-changing, and conventional weapons can barely harm them.
At a life-or-death moment, he unexpectedly gained a golden finger:
He could briefly take over the bodies of the fallen, gaining their memories and skills.
Borrow a corpse for ten minutes, learn the enemy's plans, and turn the tide of battle.
While others analyze intelligence to predict the enemy's moves, he goes straight to the dead for evidence.
During a century-long war of attrition, he quietly changed the course of humanity's survival.
In the end, he uncovered the truth behind the ignition of Earth's core, using himself as the catalyst to spark a new home on Mars.
He sacrificed his body, his consciousness dispersing into the quantum sea, to protect the dawn of the Xi Realm forever.
He is a traveler along the passage of the dead, and the guardian of the spark among the stars.
