The Green Blight erupts, and the world falls.
Crops wither overnight, and the living turn into bloodthirsty, green-skinned corpses.
Three months later, food supplies are gone, order has collapsed, and humanity has retreated to its last refuge.
Lin Yang wakes in an abandoned tool shed, his left arm infected and with nothing to his name, except for an experimental tomato seedling marked "X-7."
He thinks he won't survive three days.
But the moment the tomato ripens, he bites into the first fruit. The burning sensation of infection subsides, his exhausted strength returns, and life energy begins to flow through him.
It turns out that in this hopeless wasteland, seeds matter more than guns.
Some want to steal his seeds.
Some want to use him.
And others have their eyes on the secret he keeps hidden: a seed bank buried underground, a sealed mother plant, and the true source of the Green Blight.
The Black Scorpion Gang has its guns trained on his shack.
An envoy from the Red Leaf Society is knocking at his door.
And Lin Yang has only twelve glass tubes of seed samples, a dilapidated greenhouse, and a seed preservation specialist who just crawled out of a pile of corpses.
Things look grim.
But there's still a chance.
"Give me one seed, and I can grow a future."
