He attempted to separate a small segment of the intestines and then tied it off before cutting it.
[Separation Experience Points +0.2. Ligation Experience Points +0.2. Cutting Experience +0.2.]
Good heavens, this is incredible.
It seems like the system bug he found was even bigger.
Previously, earning 0.2 Separation Experience required him to completely separate the targeted intestinal segment. Now, by skimping and only separating less than 1.5 cm, he could immediately gain 0.2 Separation Experience Points and 0.2 Cutting Experience Points after cutting the separated intestines.
It turns out, the most valuable part was the rat's intestines.
He was extremely thrilled and began to repeatedly perform three motions: separating, ligating, and cutting, then reaping the experience points of these three medical skills.
The rat's large intestine, small intestine, and cecum together totaled around 100 cm in length.
A single separation and ligation required about 2 cm.
