Butterfly Call.

''Whew…'' Isaac took a deep breath after managing to complete his errand without any problems.

He put the bag down on the ground and the Flintlock Pistol next to it.

The leather pouch was hanging from his waist, so that he doesn't have to carry it by hand.

But, now, he untied it and put it next to the Flintlock Pistol.

''Haahh…'' He sat down and leaned on the rock wall. He used his sleeve to wipe his sweat and felt surprisingly exhausted.

Isaac had to stay on full alert during his run and had to run almost half an hour without stopping.

Also, digging the hole was perhaps the most exhausting part.

He glimpsed at his fingers, which were dripping with blue blood.

He had to use his nails to increase the digging speed, which unfortunately caused him to bleed.

The pain was even more vivid after the 1% increase in pain, and it felt very uncomfortable.

Also, the temperature was decreased to such lengths that he thought he was on an ice bath.
