The sky is like a soldering iron, burning meteorites intertwined with human nuclear fire, burning civilization into ashes. Three years later, in the wasteland shrouded in radiation dust clouds, the survivors struggled in despair and awakened a power called "Inscription Power" - at the cost of accelerating the increase in entropy, in exchange for the power to fight hell.
High school students Cai Tian and childhood sweetheart Xu Han witnessed the end of the world on the day of the college entrance examination and struggled to survive. The power of "annihilation" that Cai Tian unexpectedly awakened ran counter to all "inscriptions" - it swallowed up energy and reversed the increase in entropy, at the cost of its own horrific carbonization backlash. When he used this forbidden power for the first time in a crisis to protect Xu Han's mother's photo, the deathly gray fire that bloomed in his palm swallowed up the flames, leaving only strange ash butterflies on the ground. The question "What kind of monster have you become?" Pushed him deeper into the vortex of fear.
During their escape, they reunited with their former "Transparent Man" classmate Wang Yiyi (Night Cat). This girl with the speed of "Cicada Shiyu" mysteriously guided them to one of the last refuges in the wasteland - the Rusty Iron Regiment. However, there is an undercurrent inside the seemingly solid steel fortress.
Cai Tian struggles with the weirdness and backlash of his own abilities, Xu Han uses his "analytic eye" to explore the truth but is shocked at every step, and Wang Yiyi's position is confusing. When the question "When countless reincarnations have no results after all, what is the meaning of this reincarnation?" Echoes in the wasteland, can the three of them find their own path amidst the cracks in the trust of the Rusty Iron Group and the hunting of external forces, and uncover the shocking secret behind the devastating meteor rain? Is the power of annihilation a curse, or the only light of redemption in the wasteland?
