Solar flare + unknown virus, 90% of humanity is gone.
Of the remaining people, half turned into zombies and half were eating each other.
Li Yang hid in the basement with only half a bucket of dirty water and a rusty hammer.
Until he awakened a panel——
[Decomposition: Sofa → Fabric + Sponge + Wood]
[Synthesis: Wood + Stone → Stone Ax]
[Evolution: Stone Ax + Iron Ore → Steel Ax]
Give him a piece of scrap metal and he can craft a knife.
Give him a ruin and he can build a stronghold.
Give him enough time and he can form a civilization.
But when the blood moon rises, a roar comes from the ground,
Li Yang discovered that what he wanted to synthesize was not just weapons——
But it is humanity's last hope.
