Chương 1123: Underground Coffins

Rex, who had been waiting at the entrance, stuck out two fingers and pointed at his own head then at the mouth of the cave.

Simbady signaled him that everything was fine on his end.

Rex thus nodded in approval, turned around and walked into the cave.

Simbady looked up and saw the air hoses suspending above him. In the past three days, he had not only learned the basic operation of the diving suit but also diving gestures and techniques. It was extremely important to monitor these two hoses, and that was why the salvage required two people.

As a device to supply oxygen, the hose was connected to an air pump powered by a steam engine, which constantly circulated the air in the helmet. If one of the hoses was broken or clogged, the consequence would be fatal. Therefore, he had to be extremely careful when changing his direction or passing through narrow, treacherous areas.
