When an invisible haze quietly enveloped the world, a "Nirvana" plan planned by an extreme genius "mentor" aimed at "purifying" mankind with genetic weapons was quietly launched. Cities are paralyzed, lives are dying silently, and human civilization is in danger.
In this desperate situation, an elite action team code-named "Qingyuan" was ordered to take over. Captain Xiao Rui, with his steely will and keen insight, led the team members - technical genius Wang Xiaochuan, sniper elite "Nightingale", assault warrior "Knife", etc., From the smoke of the rainforest laboratory to the secret battle in the international city; from the tracking of the northern grassland, to the assault of the deep sea fortress; until the final showdown under the Arctic ice cap. They transcended life and death, paid heavy sacrifices, and gradually uncovered the crazy truth about the "mentor". They raced against time to prevent the full outbreak of the world-ending crisis.
However, the dawn of victory did not bring eternal peace. Although the entity of the "Mentor" was destroyed and its core conspiracy was shattered, the scattered technological legacy, the lurking remnants, and the "fire" that has carried crazy ideas and sailed into deep space are still like the sword of Damocles, hanging high above human civilization.
"Quenching the Frontier" is not only a military science fiction masterpiece about resistance and salvation, but also a hymn dedicated to the guardians who never give up in desperate situations. It tells the story that when the darkest moment comes, there are always people who are willing to turn into sharp blades to pierce the darkness and fight until the last moment for the faint hope. The story comes to an end here, but the mission of "Qingyuan" is far from over. Their eyes have been set on the other side of the star sea, and a new journey has just begun.
