Seven days later.
During these seven days, the Constant Star Train has been mining in the island's center. They've never mined so effortlessly before, with absolutely no monsters to disturb them, it felt as safe as a beginner's zone, not like a high-level area at all.
The seabed is mostly located in the deep sea, the higher the level, the deeper the activity area.
There are almost no monsters on the sea surface.
Water and land mind their own business.
It was utterly safe and peaceful.
Seven days' time is more than enough for many things to happen. The mining robots are busy day and night, working 24/7. When it comes to labor, humans are still far behind robots.
Currently, there are 50,000 mining robots diligently working.
