Synthesis Wizard - Chapter 16: Synthesizing a First-Rank Potion

It always starts with an accident.That’s how all these stories go. One moment, you’re minding your own business, and the next, you wake up in someone else’s body. For Caspian, his accident started earlier than he even knew.Maybe it began when his sister got him into romance novels? Or when he started really sympathizing with the villains at the ends of books? He’d never know. It was too late to worry about it now.For now, he had to find a way to fix this nightmare, or rehabilitate his image, all while trying to free himself from the fate set out for him. All because of the damn “gods” who he'd cut a deal with.These were the only two options he had available, and he wasn’t sure he could succeed at either. The man he had taken over for had been…a true piece of work. And the secret villain of the book he had been reading before he passed.It had been a harem novel. A reverse harem novel.He was trapped in a huge ass CASTLE with a bunch of men who hated him because he was taking affection and time away from their shared wife. All Cass wanted to do was be a good person, not mess around with this poor woman and her far too handsome husbands.But why would no one leave him alone? Was he too suspicious? And why, after going out of his way to avoid them like they had asked, did they keep pestering him?And where did the heroine go?How was he going to manage three, handsome men without the heroine?

A novel revolving around being transported to another world with an op system. The mc spends his day chasing skirts and doing missions to level up. A standard journey to the top with lots of girls from various animes and games with a twist of that gaming feel (hunting mobs, doing missions).

——”You like to peek at your sister’s game so much?”
——”No, narcissist.”
——”Oh. Then… why is the support ring in your hand marked with my name?”
Wen Qi—competition leader, captain of the school’s women’s basketball team, president of the student union. Everyone in Entai No. 1 Middle School knows the name Wen Qi.
But Bian Qian hates Wen Qi very much.
In the second year of high school, the arts and sciences were divided into classes, and the two of them were assigned to the same class by accident. Bian Qian became the class monitor, and inevitably came into contact with Wen Qi.
Early self-study:
Wen Qi: “Master squad leader, how do you pronounce this word?”
Bian smiled slightly: “There are notes below.”
Afternoon self-study:
Wen Qi: “Sir, I don’t have the test paper with me, can I read one with you?”
Bian smiled slightly: “Did you eat the test paper I just handed out?”
Evening self-study:
Wen Qi: “Sir, monitor, I don’t know how to do this question, please teach me.”
Bian Qian looked at the basic question, and screamed in his heart: You got 149 in the fucking math test, ask me what 1+1 equals?
After school:
Wen Qi: “Ban…”
Bian Qian: “Get lost!”
Bian Qian thought that she and Wen Qi had met for the first time, but she didn’t know that this encounter was actually a reunion that Wen Qi had planned for a long time.
