As soon as Anon moved the box from its position, he discovered a large metallic gate concealed behind the missile launching cannon.
"If I recall correctly, this cave used to be much larger than it is now... There was a big metallic door at the front leading to a very spacious room with various instruments and chemicals," Faith explained while lightly touching the missile launcher.
"It doesn't end here," Anon said.
"What do you mean?" Faith inquired.
"Come, take a look at this," Anon pointed to the metallic door.
Curious, Faith approached the door and observed it closely.
"Oh, you're right... This is the door. If I remember correctly, it leads to the room I just described to you. But to open this gate, we have to remove the cannon from here, and I don't think the two of us will be enough to even budge it. It's fixed in place, see its base?" Faith pointed at the bottom of the cannon.
