Iron Jaw led the main force of the mercenary corps along with Tanaka's clone to dive underwater, but a part of the crew stayed on the ship to keep watch.
After all, the ship and their remaining employer still needed protection.
Being betrayed by the employer, or even getting killed?
Iron Jaw hardly considered the possibility of that.
After all...why would they?
On this entire ship, apart from the dozen or so Pukis wasting magic potions and the two employers, everyone else was on their side.
If they had no ill intent, the employer should thank their lucky stars, how could they get betrayed by them?
If something really happened to them underwater, the brothers left on the ship definitely wouldn't let it slide easily.
However, the now-dead Iron Jaw didn't know.
Just shortly after they entered the Underground City, those crew members who he thought "wouldn't let it slide" had already united to turn the ship around and sail back in the direction they came.
