The world suddenly fell into a mysterious doomsday game. Xiao Yang woke up on the highway and found that he and all healthy humans aged 18-45 were involved in this "road survival game." With the awakened "god-level selection system", he obtained a modified main battle tank at the beginning and fought his way through the doomsday highway where zombies were rampant and resources were scarce.
Mechanical expert Lin Yuqing, MD Su Waner, and electronic engineer Xia Yufei have joined the team one after another. The four heroines with different personalities each show their strengths: modifying armor, developing vaccines, cracking electronic equipment, and establishing early warning systems. When the acid rain disaster strikes, when predators besiege, and when the truth about the military's secret laboratory emerges, this steel army continues to grow in blood and fire.
"This is not a game!" The warning on the mysterious radio echoed day and night. Driving an ever-evolving tank, Xiao Yang led the army of beauties to break through the fog and head towards the source of the virus. When it is finally discovered that this doomsday is actually a screening experiment by higher civilization, they must make a choice - become docile test subjects, or use artillery fire to blast open the cage?
