In his last life, Lin Chen was betrayed by his most trusted brother and loved one, and died of hatred in a zombie siege. The penetrating wound on his chest and the roar of the corpses were his last memories.
Unexpectedly, he was reborn one month before the end of the world - there were still thirty days before the bloody rainstorm that covered the world.
What's even more surprising is that along with rebirth comes a mysterious system that can contract with all things. The sunlight shining through the window lattice can be contracted, the pot of green radish on the window sill can be contracted, and even the tap water that is about to be polluted can become a tool for him to accumulate strength.
Light energy reserve, plant affinity, toxin resistance... Relying on the system and past life memories, Lin Chen frantically hoarded supplies before the end, tempered his body, and made plans in advance.
He knows where there is a safe haven, knows who will betray in the chaos, and understands the laws of species mutation and the secrets of crystal nuclei.
When the bloody rain poured down and the zombies screamed and tore apart civilization, Lin Chen picked up the fire ax and stood under the orange-red sunshine, with a cold light shining in his eyes.
"Zhao Kai, Su Ya, whatever you owe me, you will pay back double in this life."
This time, he not only wants to survive, but also uses the contract system of all things to control light energy, tame mutant species, carve a bloody path to the top in this wasteland, and become the most awe-inspiring enlightened person in the apocalypse!
