In the 1980s, for mischievous children who had no love for studying, joining the army and becoming part of a military family was the best path forward.
After an unexpected incident, Ma Rulong discovers that he has a special constitution. An officer with the same unusual trait tricks him into enlisting.
The boy stumbles into the Sixth Path, thinking his unit is a paradise. Instead, he finds himself stepping into a living hell.
A secret unit with an extraordinarily high death rate, whose designation to the outside world is Zero.
This outlier unit serves the country's scientific research, but its missions are bizarre beyond belief.
The unit's structure is strange, and in the mysterious Sixth Path, simply surviving is the greatest success.
His pure-hearted childhood companions: Taozi, Ruibao, and the five brothers of the Gao family.
After joining the Sixth Path, he meets comrades at the base in the Upper Three Paths: Huowu, Shuihai, Baolie, and Bingren. They become his reason to keep going.
After surviving a mission, he unexpectedly enters the underground world of the Lower Three Paths beneath the military base, where he discovers an astonishing secret about Earth that humanity has never known.
Earth awakens. Humanity seeks redemption. Shuihaier dies beneath the glaciers of the far south, and the Sixth Path base suffers devastating casualties. These man-made mistakes send Ma Rulong into a furious rage. He rages for the woman he has lost. If Heaven will not uphold justice, then I will. I will slaughter every last one of them, and avenge the sorrows of this world.
