After going into the stone door, they were surprised!
There was a laboratory. There were eight accesses, including the stone door. The accesses could help people go to different places. When there was any danger, people could escape from any of the accesses.
They found lots of equipments in the laboratory. With the equipments they were almost able to make everything. "That's why the bad guys are strong," said Physics. "Let's destroy them," said Flute. "No," Maths said, "they can help our town a lot." They had different opinions and both of them had a point. Others were not able to stop the discussion.
Unexpectedly, many baddies came back. They shut all the accesses. The Justice seemed to be in great danger.
