As colossal sea beasts blot out the sky and tear apart humanity's last fortress, and his comrades fall one after another to endless waves of monsters, top geneticist Lin Mo finally turns a mysterious meteorite from beyond the stars, the "Star Core Shard," into a spark that can reverse humanity's fate. He and six companions who have stood by him through life and death inject themselves with gene serum, breaking the limits of life and transforming into human war gods! Their fists shatter orcas; they tread through the air! But the horrors of the deep sea exceed all imagination. Ancient behemoths from millions of years ago awaken, and human civilization finally sinks into the waves of despair.
When Lin Mo opens his eyes again, he's back three months before the disaster begins! He's still a top sophomore student at university, absorbed in experiments, and has just broken up with the campus belle. The time he wasted wallowing in heartbreak in his previous life? No! This time, all he feels is cold urgency and boundless fury.
Armed with memories of the apocalypse and future technology, Lin Mo shakes the establishment with astonishing predictions and cutting-edge knowledge, making his way straight to the heart of power! He reunites the six companions from his past life, who have yet to awaken, and uses the "Star Core Shard" to mass-produce the "Liberator" serum, capable of breaking the shackles of the human genome, with the entire nation behind him! He tests it on himself, endures the agony of his genes tearing apart, and awakens first: his body is the ultimate weapon! The Seven return, their power shaking heaven and earth!
Time is running out! A doomsday fortress named "Spark" rises from the plateau. A sweeping nationwide selection seeks genetic sparks from among a million soldiers! The first "Spark Warriors" are transformed by the serum and hellish training, their flesh and blood now capable of standing against mechs!
