The first mine pit opened is slightly lower in terrain, perhaps with the intention of saving some manpower and resources, this mine tunnel is cleverly opened, starting from a lower point, presumably to quickly excavate the diamond mine.
Moreover, once inside the mine tunnel, Huo Sining discovered that the soil here was the loosest, with few rock layers, making excavation faster.
However, after entering the mine with Matthew while wearing a safety helmet, Huo Sining and her group quickly discovered a problem.
Oil lamps were installed on the walls inside the mine pit, allowing the mine tunnel to not be too dark and making the ground visible, and at the same time, there was also a mining lamp attached to the safety helmets worn by Huo Sining and her team.
This mine tunnel was dug very deep, with a vertical distance reaching as much as thirty meters, but the further in they went, the more severely Huo Sining frowned.
