In the wasteland world after the "Great Blight" event, rust fungi infected most of the earth's creatures, and humans retreated to the last Ark City. Resources are exhausted, order is broken, and survivors are lingering inside the high walls.
During a scavenging mission, botanist Lin Zhi discovered that the infected phage was guarding a mysterious blue flower. He named it "Sprout" - a substance that not only delays infection but also inspires healthy evolution in humans. However, the elders who control Ark City will regard the "Sprout" as a threat and attempt to use it as the ultimate weapon to control the people.
Lin Zhi, who was forced to flee, and Shen Yi, a former special forces soldier, met scattered settlements outside the wall that had already embraced evolution. They discovered that this seemingly destroyed world was being reborn at an alarming rate. The future of mankind is not to huddle within high walls and wait for death, but to bravely walk towards that wild and vibrant land.
When the remnants of the old world and the evolved new humanity are about to collide, Lin Zhi must prove that after destruction, there must be new life.
