The excavation work had been abruptly halted while it was just warming up, leaving a sense of uncertainty. Feng Yi looked up and noticed that it was already late. Perhaps it would be a good idea to rest early and reevaluate the situation the next day. After all, life goes on, excavation works would continue. If he lost his shovel, he could find something else to replace it. Carrying this thought, Feng Yi, feeling somewhat overburdened, headed towards his insulated tent...
He had set the insulated tent about ten meters underground. This depth provided effective defense against day-night temperature changes. It took him half a day to build the tent, which was about 20 square meters and contained all sorts of garbage. He had picked out some things from the rubbish heap that were too good to throw away but too bland to eat or use.
