Of course, the underworld has nothing to do with martial arts; it just mixes in a little bit of axe instructions, close-combat techniques, and firearms skills. After use, the average level achieved is around basic Level 3-5, but it doesn't stop players from calling it that.
The classic part of this skill is that the actions, postures, and slogans are all filled with port-style gang black humor, making players chuckle, while the real improvement in combat ability is limited.
This improvement is already a doubling for the town residents who haven't fired a few shots in a month, raising their skill from 5 to 8-10, and they won't run around aimlessly or be at a loss due to a couple of gunshots, plus it includes the unique situational flair of the underworld.
With cries of gang rules, dancing to the Axe Gang's moves, this group charged toward the Black Blood Gang, and they actually had a bit of momentum.
