Begging for an Emotion Card

One day, Chen Yin was strolling along without a care in the world. Suddenly, a super-cool voice rang in his ear: "Do you want to get into Tsinghua, Peking University, or Stanford? Do you want eyes that shine like lightning and to be loved by everyone? Do you want to marry..."

"Wait, can you get to the point first?"

"Here's the deal. I'm an intelligent being from the future, and I need you to collect the emotions of people from different worlds so I can gather enough power to return to the future. So you have to help me!"

Then the System gave Chen Yin seven Dragon Balls... No, seven emotion cards. They represented lust, hatred, guilt, fear, contempt, anger, and grief.

The System said in its cool voice, "It's simple. You just need to make the people around you feel these seven emotions. Anyway, see that guy riding a bike to your right?"

Chen Yin was stunned. "This setup is way too random. What exactly do you want me to do?"

"Hit him, then demand compensation."

So Chen Yin got Guilt ×4, then the guy came to his senses and beat him to a pulp.

"You little jerk! You tried to scam me!"

This is the story of a laid-back male lead who gets randomly selected by the System and travels through different worlds, constantly collecting emotions and clearing stages. No couples, though there are female characters and possibly ABO elements. All in all, it's a bit of a hodgepodge. Don't read if that's not your thing. Not romance, not danmei. The male lead is committed to staying single for a hundred years.
