Yang Zhuo is an ordinary university student who can change the rules of the world.
He tried one first: humans are not allowed to lie.
The System thought that was too demanding, so it changed the rule to this: anyone who lies gets red text over their head for ten seconds.
Roommates bragged, streamers sold products, and couples made promises to each other. As they talked, everyone started looking above one another's heads.
Yang Zhuo was enjoying the show when he casually said in class, "I've already organized everything."
[I've already organized everything]
The whole group looked at his empty document.
Fine, the person who makes the rules doesn't get special treatment either.
Then let's try another one.
A shopkeeper had just written "Original price: 99" when another line appeared beside it: Lowest transaction price in the past thirty days: 69.
The owner picked up a rag and wiped away "Original price" first.
One more rule: the first time you sincerely compliment someone face-to-face each day, both your phones get a ten percent charge.
People who usually couldn't stand each other suddenly started searching for each other's good qualities as soon as their batteries ran low.
Yang Zhuo finally learned how to compliment people, too.
Unfortunately, he did it too early. At night, his phone ran out of battery, and ten more compliments wouldn't help.
Each rule lasted seven days. The stubborn scrambled to make excuses, the clever looked for loopholes, and Yang Zhuo busied himself cleaning up the mess he'd made.
What should he change next?
"Let me think about it first. This time, I need to include myself in the rule."
