At the back of the castle, there were no bulges or protrusions on the wall. Without professional tools, it would be almost impossible to get in from here.
Were it not for the black color of the figure below that was clearly visible against the white snow under the castle, it would be difficult for Su Mo to spot at first glance.
The figure seemed to be looking at the castle wall, studying how to climb up this smooth back wall.
It took three to five minutes, but when Su Mo's eyes were a little strained, the figure finally moved.
Seeing what followed, Su Mo suddenly burst into laughter.
This "man in black" seemed to have opted for the same method Su Mo used before to attack the lion people's camp!
To dig a hole!
Does he intend to dig a hole under the kobold castle?
Seeing that the man in black had started digging with a shovel, even Su Mo felt a headache coming.
