John gets a second chance at life, going back to the time before "The Gate to Another World" appeared. Betrayed in his past life as a pharmacist, he decides he can't trust anyone anymore. So, he opts for a hidden profession, becoming a poison master disguised as a regular pharmacist to everyone else.
To the other awakened ones, John is just your run-of-the-mill potion maker. 
Little do they know, every healing potion he brews is laced with deadly poison.
"John, heal me quick... Fuck! John, what did you do to me? Why have I turned bald?"
"John!!Why did my penis turn into a mushroom after drinking your potion?"
"You guys dare to drink John's healing potions? I saw with my own eyes last time, he threw a bottle of his healing potion and it directly stank a Corrupt Lord to death!"
"And that's nothing! I saw a toxic serpent bite John, and guess what? The serpent got poisoned to death by him!"
John sneered at the collapsed crowd, "I've said it before, though my potions are free, they come with some minor side effects. Want to get rid of the side effects? That'll cost extra!"

Supreme therapist：My healing potions can even poison the gods

Demon Ghoul stared at John from a short distance away.

It slowly walked forward and asked, "Master, you have always been reluctant to show yourself before. Why have you suddenly graced us with your presence now?"

Demon Ghoul eyed John up and down, feeling a touch of suspicion in its heart.

As for this undercover agent from the Moonlight City Awakeners' Guild, either he has been turned, or he's foolish enough to mistake his master.

"There's been a change in plans. So I came to discuss it with you." John said, fully immersed in his role. He could sense that Demon Ghoul was wary of him.

He need to find an opportunity to inject the venom into its body.

Demon Ghoul furrowed its brow and glanced towards the place where the battle had just taken place. The corpse of Gluttony Ghoul lay there.

John noticed the strange look in the Demon Ghoul's eyes.
