Boss Joe was never someone who would make things harder for himself in a fight...
The battle to seize the second floor went very smoothly because the gas heavily affected the second floor, so no one was stationed there.
The elite soldiers used furniture and mattresses to block the staircase from the second to the third floor, trying to prevent the gas from spreading upward and to prepare for a face-off with P·B.
But Boss Joe would never force an assault...
Joe Ga's character is such that he prefers to face off with a gun in a relatively fair environment, but he would never sacrifice his soldiers if there are better alternatives.
It's not that there were no opportunities, but P·B's lives are more precious than the enemy's!
So, after clearing the second floor and using micro-drones to conduct reconnaissance, he directly blew up the floor of the room where Musa Suleiman was located.
