Chapter 1581: A New Discovery

In the crater 100 kilometers away from Heavenly Palace City, the rover of the B City Steel Group was on a transport mission to send liquid oxygen, freshwater, food, and other supplies to their mine.

As usual, Hansen unloaded the cargo from the rover and then handed the tablet to Roger, who was in charge of receiving, to sign. At the same time, with the ease of his position, he brought some gadgets to relieve the mine engineers of loneliness.
