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

[Victoria]: John, I've completed my first transformation.

[Victoria]: But there are still matters at home that need my attention, and my sister has returned. Now that the other world portals in the Star City have all closed, I want to take this time to bury my mother.

[Victoria]: So, I might be a bit busy and won't be able to join in the fight for now.

[John]: That's alright, I'm heading to the Moonlight City. You take care of your matters.

[John]: On the day of your mother's funeral, remember to contact me. I'll come to offer flowers.

[Victoria]: Okay, I will let you know in advance.

[Victoria]: Wish you a safe return.

Just as John was about to put away his phone, he received another message, this time from Andre.

[Andre]: John, I've just contacted the president of the Moonlight City Awakener Guild and obtained the local information on the other world portals.
