If it was weather like any other, there was nothing that Luo Yuan could do.
However, as the earth was now experiencing a nuclear winter, the temperature outside was -60 degrees Celsius. Apart from the holes, the ground was covered in snow. It was almost no difference with the north and south poles, which might be possible to deter the volcano from erupting.
The layer of ice on a cold -60 degrees Celsius day was as tough as a rock, which thickened the earth’s crust. Although the ice layer was not thick enough yet, it would be much thicker as time went by. Furthermore, due to the unique concave terrain of the holes, it was easier to form bowl-shaped ice layer as a barricade of the volcano that was about to erupt.
That was just his estimation. Looking at the time, it was impossible to stop the eruption completely, but delaying it was plausible.
