A meteor shower brought the apocalypse to the world.
A dark red liquid clung to the meteors' surfaces. As they passed through the atmosphere, it dispersed into the air and became a deadly zombie virus. Where the meteors struck, they shattered, and the red liquid seeped into the ground. It was a purifying energy capable of making all things evolve.
After falling off a cliff, Su Han transmigrates into a dead city overrun by zombies, waking up on a rooftop. He also binds to the “System of All Things Synthesis.” Its function is to combine two identical items into something of higher quality. But there are limits to synthesis: from Tier One to Tier Two, then Tier Two to Tier Three, every upgrade is incredibly difficult. Naturally, the first synthesis comes with a bonus.
Starting from the rooftop, he must search for a chance to survive in this apocalypse.
