There is a second-hand bookstore in the old town of Jiangcheng that has been losing money for many years.
Lu Yuan, a part-time student in the store, is pale and thin. He can't even climb a ladder. He looks like an ordinary high school student who can be overwhelmed by life at any time.
The skinny old man who often came to read newspapers thought he was a poor honest man;
The underground boxing champion, who was on the run from his enemies, felt that he was a worthless wimp;
The cold-blooded killers who came to the door with black umbrellas didn't even bother to look at him.
Until one day, multiple forces collided in the second-hand bookstore.
Lu Yuan, who had been trembling with fear, accidentally knocked over a glass of water.
The water droplets splashing all over the sky hovered strangely in mid-air, turning into eighteen thousand invisible water swords, which instantly penetrated the throats of all invading enemies.
Seeing the mess on the ground, Lu Yuan sighed helplessly and picked up the rag:
"I only earn a part-time fee of ten yuan an hour. Why do you force me to work overtime?"
