The Chairman of Pharmaceutical Company is a Poison King

300 years in the future, Earth was engulfed by mana.

I was a 'Mana Reject'—someone whose body treats mana like a lethal poison.

Unable to Awaken, I was just waiting to die.

That is, until one day...

My soul connected with its counterpart from another dimension.

The absolute master of Murim, the Absolute Poison Demon... Dang Gunak.
