The baddies came back. There were six baddies. They were Liu Zhuang, Wei Changxu, Yao Xinyu, Sun Dianbo, Shang Yuepeng and Zhang Xince. Liu Zhuang was the strongest one and the captain. Others all followed Liu Zhuang to do bad things.
The baddies came back with Li Qianmo roped. When people in The Justice was exploring the cave, the baddies found The Justice. They tied Li Qianmo and then used a bomb to destroy The Justice.
"It seems that The Justice has been destroyed," said Physics. Wei Xueqing was so angry that she wanted to use the pistol to shoot at the baddies. "Don't do that," Tangent said, "it may hurt Li Qianmo." Maths used the ax to beat the bad guys. But the baddies wore clothes made of steel and diamond so he was unable to hurt them. Suddenly he came up with a good idea.
He let Flute and Fong made some robots. The robots could make fire. The robots went to make fire. The steel melted and the diamond burnt. But after that baddies kicked the robots and the robots were broken.
Tangent used the drill to attack the baddies. The baddies was unable to defense that. Suddenly Wei Changxu took out a knife. He pointed at Li Qianmo, "If any of you come up, I will kill her!" Tangent had to fall back. They discussed how to save Li Qianmo. Finally they made the plan. They used the things in the laboratory to make a kind of bullet that can blow up without hurt. Fong used the bullet to shoot at Wei Changxu. "Pong!" Wei Changxu was surprised and dropped the knife. They saved Li Qianmo at the same time.
