Reborn for 6 Days: I'll Be the Badass in the Apocalypse

Plot Synopsis

In my previous life, I was stabbed in the back by my brother. I was reborn six days before the outbreak of the zombie virus! This time, I hoarded all the modified artifacts in the hardware store in advance. Carrying a composite engineer's gun, I swept through the convenience stores. But then I bumped into the school beauty with strange black lines crawling on her neck? The mutated crawlers were blocking the door in the church. I took out the green crystal stone with a sneer and said, "I'm definitely taking this wave of experience points!"
