The tunnel(In delopin)

In some Robloxia tunnel, a case was reported about 2 missing people. The reporter comments that her 2 children had to go to school but time passed and they did not return. They ended up finding their fingerprints and some of their objects in a strange tunnel never seen before. The police, seeing this, sent someone to investigate this cave and closed it to civilians. The police investigated thoroughly and still did not find any clues until they decided to send a small group to investigate the tunnel.
