With the plan laid out, Tristan led his team forward. Damien's team stayed close behind, but far enough away to cover Tristan's back if someone came from outside.
With how narrow the entrance to the basement was, and the way it was positioned below a short staircase, there's been no point in bringing in too many people at once. Especially since Tristan planned to teargas everything inside.
'Ten people will probably be a huge overkill for this raid. But if it won't… Yeah. With what Gospel can do—how do I know he's not as dangerous in combat as I am? He also has a system, and I still don't know what it does!'
The basement door was closed on a deadbolt from the inside—Tristan spotted the deadbolt immediately through the crack between the door and its frame. He also saw hints of light from the other side.
