Traveling through the parallel world, Lu Shu became a college student. In addition to studying hard, he would diligently go out to work part-time during every holiday.

One day, while he was in class, a group of heavily armed police suddenly burst into the classroom.

"Lu Shu, right? Come with us!"

In the detention center, the police looked at the documents in their hands with solemn expressions;

"My classmates are enjoying their vacation, what are you doing?"

Lu Shu answered honestly: "Work part-time to save tuition."

“Why do you go abroad to work?”

"You are not allowed to serve as mercenaries in our country."

"Then why are you ranked 9th on the killer list?"

“I worked several jobs on the side.”

"I heard that the SEALs wanted to recruit you as a foreign soldier. Why did you refuse?"

"They said commissions are not paid daily."

"You also blew up the island country's sacred toilet?"

"Well, they owe me wages."

Policeman: "Last question, is ak easy to use?"

Lu Shu: "It's not easy to use because blood will splash on your body."

Lu Shu answered the question honestly, but found that everyone in the room seemed confused.
