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

John thought for a moment and then added, "For the rest, feel free to improvise. Try to express hatred as if you were on your deathbed, something akin to intimidation and warning. Got it?"

The necromancer frowned deeply after hearing this, seemingly filled with doubt. However, to avoid further suffering, he obediently nodded his head.

"Alright, take a moment to get into character. I'll say 'action,' and then you start." John adjusted his phone to video mode, aiming it at the necromancer. "Three, two, one, action!"

The necromancer stammered into the camera, "Two months from now, the third wave of the other world portals will descend upon Earth. At that time, then..."

"No, no, no!" John stopped the recording. This guy had no acting talent whatsoever. It was obvious he was reciting lines, and he even had to pause to think.

John sighed, exasperated, "What were you thinking? Where's your expression? Your tone? It's full of flaws!"
