To Save My Sister, I Joined a Cult

Three hundred years after the disaster, the nine base cities are like isolated islands floating in the ocean of the apocalypse, protecting the last fire of mankind. Ye Jin struggled to survive in the cold steel forest, his sister was terminally ill, and his father joined the mysterious religion with his last hope, and he also joined the mysterious religion. When Ye Jin discovered that the so-called "oracle" was nothing but a hoax and that his loved ones had been mentally controlled, despair ignited his fire of resistance. He transformed from a believer to an apostate, walking between lies and faith, subverting his enemies with their own methods. Ye Jin, who became the leader of the cult, was also trapped in the center of the whirlpool of power. There are mountains of secrets that need to be buried, careerists in the dark are coveting his position, and the once pure protective heart has become increasingly blurred under the influence of intrigues. When faith is reduced to a tool to control people's hearts, and redemption becomes a transaction with a clear price tag, how will this man, who once fought against the world as a mortal, tear through the haze of the apocalypse and find his own path to salvation amid the torn apart of desire and true love?
