The Justice had had many members, such as Tangent, Flute, Fong, Maths, Physics and Li Qianmo. The organization helped people a lot.

However, the baddies still did bad things. One day a girl was kidnaped by baddies. The police (Why didn't the police come to conflict with the baddies before? Because the baddies have weapons that are strong enough to destroy the police station.) searched but couldn't find her. They called The Justice for help.

Hearing of the thing, members of The Justice rapidly decided to go and save the girl.

Tangent, Flute, Fong, Maths and Physics went to search for the girl. Physics, a boy who had a good sight, suddenly found a piece of paper with "Help! Baddies kidnaped me!" on it. "Come here!" he said. Others went to Physics and read the words on the paper. Suddenly they found a lot of feathers on the ground in a line. "Let's follow the feathers." Physics said.

They successfully found the house where the girl was tied. "Hey girl! Are you OK?" The girl didn't answer because her mouth was stopped up. They found that nobody else was in. Tangent went and untied the girl. She asked, "Who are you? Why are you here?" The girl said that her name was Wei Xueqing. "I found a lot of weapons in a cave. But when I was about to call the police up, the baddies found me. They tied me and warned me not to tell others. We have to go quickly." But Tangent found lots of gunpowder in the house. She said, "If we don't destroy the gunpowder, baddies will use it to do bad things." Others agreed. Tangent found a piece of fuse that is 3 meters long. She ignited the fuse and they quickly run out of the house. When they came back to The Justice, the house had already been in ruins. Luckily, no people was hurt.
