Programmer Lin Mo struggled to survive in the apocalypse for five years. In the end, he was betrayed by the people he saved and was pushed into a swarm of zombies to die. Before he died, he awakened the god-level synthesis system - which can combine any two items into a more advanced item. However, it was too late, he was torn apart by zombies as soon as the system was activated.
When he opened his eyes again, he found that he was reborn seven days before the end of the world.
This time, he is no longer the useless programmer who can only write code.
He wants to stock up on goods, upgrade, and crush all the people who have harmed him in his previous life one by one.
