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 put on his robe and came to the table.

The waitress took out a folded note: "Sir, President Eartha asked me to give this to you."

"Thank yo.," John reached out to take the note, unfolded it, and read it. After reading the message above, he couldn't help but smile.

[Eartha: Dang dang~This is the love breakfast I made for you. I have something to do and need to go back to the guild first. I'll be back around 10 o'clock. Let's take a helicopter together and head to Star City then. By the way, I have also prepared a handsome outfit for you. I will have someone deliver it to you later. You must dress more formally today. See you then!]

John put the note away and looked at the breakfast in front of him, which looked quite good.

It seemed Eartha wasn't lying about her cooking skills.

The waitress picked up a cup and asked John, "Sir, what would you like to drink? Milk, coffee, or tea?"

"Coffee, please. No sugar." John replied.
