Dark Space
After Ace rested for three whole days, he was finally at this peak condition and started to make his way toward the surface.
However, his joyous expression became sober when he was only five hundred meters away from the surface because the surrounding soil started to become wet, and as he moved slightly more upward, he was now dealing with clay.
'Don't tell above me is a water body?' Ace knew it was likely the case.
Now, if he dug any further, it was most likely that this place would sweep by water, and he might wash all the way down or, even worse, this entire passage crash.
So, Ace decided to use another method. Instead of digging like before, he took out a grade-5 barrier formation and covered himself and the walls with that barrier like a sporting pillar.
Afterward, he started digging again while the formation barrier supported the passage.
