A Certain God-Killing Immortal God

Gu Han is an obsessive gaming fanatic. After an unexpected turn of events, he becomes one of the Chosen and receives the Legendary System! Blood and sweat pave the way to a path of strength that stretches into infinity, as he sets out to forge a legend! So what if you turn the world's difficulty up to the Asura level? So what if you transmigrate me straight into a laboratory to endure endless torment? So what if my path to legend is blocked by a host of ambitious overlords?

As long as I know there's a chance to keep playing this game and beat it, that's all that matters., Gu Han

The first world, Demi-Humans, begins with a bang!

I never thought... I'd become Izumi Shimomura's older brother...
