The moment Markus landed on the ground, first thing he did was break the window to grandpa's bedroom and throw a poison bomb inside.
The poison bomb was made by him while gaurding the poison garden grown by professor.
But its dual effect was the smoke it produced along with the poisonous gas. This made the men unable to see much while Markus entered easily, striking at them one after another.
He was precise enough to strike at their vital points, going for all one shot kills. One had to appreciate Markus's killing aura. It never mattered whether he was carrying a gun or blade, no one had ever managed to avoid his blow and stay alive.
The way Markus was already on his slaughter mode, slashing seven men within a minute, the rest of room could only imagine the amount of determination he had to kill them all.
Plus they were unable to decipher Markus's killing pattern, as shouts for help could be heard from all corners of the room.
