Tomb Robbing Bottomless Pit

During the day, Hua Shao, and Zhang Yan saw a news on the Internet saying: On September 10th, geological experts discovered a "bottomless pit" that was 50 meters long and 40 meters wide in a place in Sushan. The geological research team took wires from the "bottomless pit" and descended it for more than 3,000 meters without reaching the bottom. The stones around the bottomless pit are extremely hard. How it was formed, the geological experts couldn't explain. This aroused the curiosity of Bai Ri, Hua Shao and Zhang Yan, because they especially like to study these nonsensical things.
