In 2028, seven thousand-meter giant gates descended on the earth. Behind the gates is a different world where technology is ineffective. The monster's inner elixir can give humans superpowers, but it also hides destructive traps - the more the inner elixir flows in, the faster the two worlds merge.
When the truth was buried, people from all over the world flocked to the giant gate. Until that day, the earth and the other world suddenly merged, and civilization collapsed overnight. Guns misfired, power was permanently cut off, and half of humanity perished in the bloody dawn.
Lin Mo, a seventeen-year-old high school student, swallowed the first inner elixir in order to save his loved ones, and then stepped into this ruins where ability is respected and human nature and beastliness are intertwined. Under the law of the jungle, he chose to hold on to the flame and light up the innocent people. He met the swordsman girl Su Wanqing. She used ice and blades to fight his way out of despair, back to back.
From the campus to the ruins, from being alone to the "Watcher" team, they fight against monsters and corrupted hearts. Those in power regard human lives as bargaining chips, thugs enjoy killing, and close friends may betray them in the next second. And behind all this, the pair of "blood pupils" belonging to high-level monsters are elegantly enjoying the game of raising gu.
This is the worst of times, when civilization turns to ashes and morality collapses. This is also the best time, when the fire burns in the palms and there are people who are willing to shake their fists for strange cries. Lin Mo and his companions lit a fire that refused to be extinguished in the depths of the apocalypse - not to become a new king, but to prove that the reason why people are human is that even if hell is coming, their spine will still be there.
