After confirming there was a foundation below, Lin Mo took a pickaxe and started to search inch by inch on the nearby well walls.
A foundation meant that the soil layer underneath was solid, so the entrance would likely be on one of the surrounding walls!
After searching for about ten minutes, like sweeping for mines, Lin Mo checked each section and finally found an area with a hollow space behind it, then slowly started to pry it open.
The stone slab was very thick, and despite his efforts, he couldn't budge it.
Later,
Lin Mo simply went back up again and brought down an electric pickaxe connected to an extension board.
Technology was indeed reliable!
Being so deep underground, there was no need to worry about making too much noise.
The power tool was very efficient, and after just a few hits, a notch was made on the stone slab. Using a crowbar and the pickaxe continued the destruction, vastly increasing the speed.
