As he is now near to the drug den but the problem arose as he sees several guards with intimidating statures probably having strong quirks but Rey wasn't suprised. He remembers that he created a consumable items the variable Grenade from Advance warfare these Grenade come with two variants lethal and tactical and have 3 settings to help him either killing them or distracting them. As Rey uses the tactical variant to threat settings as he throws it right behind the two guys as it check the surrounding area for other threats as he sees there are 12 guys 2 outside and the rest were inside watching over the laborers and labs as well as guarding depots where truck will pick up boxes or crates full of concealment and drugs as well. As he decided to plan out tactically like in those realistic military games or documentaries of how SF and other spec ops operatives plan and move. As he recall all of his past life memories of how military men were trained and move even though he maybe and amateur but he will adapt as much as he can.
As he move from cover to cover and looking at the distance between himself and his targets he then move one more time and peeking from his cover being a metal trashcan. He then pulled out the Man-O-War rifle with the suppressor keeping the nose less and possible as he pulled the trigger and killed one guard and another by surprise. As both men dropped dead infront of the den as he then began to inspect their things as evidence like contacts and even using his phone to hide his real identity by using someone else's phone. Then he is now infront of the door as he loaded a fresh mag into the rifle as he didn't pull the bolt since it's already loaded. Then he knocks on the door as one of the guards tried to peak but the only thing he sees is a gun's barrel then Rey pulled the trigger killing him.
Inside the den the guard sees his friend dropped from the ground lifeless as he check on what's going on until a bullet penetrate through the door right to his chest as he was in pain as the assailant entered and tapped the guard.
As the guard is dead Rey continues further inside the drug den as he checks each corner and room for anything to loot either money, scrap parts, or some expensive equipment they have in hand also shutting down the operation. As he entered each room also finding the layout of the den from documents he found in one of the rooms by he sees a big room which is where they make the drugs and also other guards or one of them are his enforcers and his boss. He then began to move immediately with both his guns ready and his grenades ready. He then used the threat setting of the tactical Grenade to read the threats as he throws it down to another spot as the grenade reads more people than last since he is inside there a limit where the threat readings are. There are a mix between red and white meaning there are civilians or workers then red ones are the guards and one of them is the boss with one who is bigger than the others. Which is his personal bodyguard and the rest are just amateur villains and thugs around the area. As for him he had to be careful since there are civilians working on the drug factory and he doesn't want to harm them since there just people so he only has 2 tactical left and 5 lethal grenades as he decided to create a diversion by blowing up their storage room. He then traverse through the corridors and stealthy pass throught some guards as well as shooting them using his pistol and arrive at the storage room where all of their supplies and since they are amateurs when it comes to weapons storage they have gun parts, guns, and even explosives.
Meanwhile with the drug leader this man was responsible for distributing not just illegal drugs but also illegal quirk boosters. Since many young heroes and even some heroes need some of these stuffs to get their performance high and at the same time fast. Until then he was talking to his phone with a client.
"Yes,Yes I know you need them but don't worry about it we are reserving some of them already and I'll send one of my delivery boys right to you and remember the same spot alright" he said at the phone as the client on The other side agreed but in a stubborn and angry tone.
After talking to the client the boss who is called Scav was a bit fustraited about the number of demands on quirk drugs were high. And he knew how difficult it was to make those drugs ever since formulas were hard to find and to remake. He slammed his fist on the desk because of how frustrating it is to convince his clients also finding fresh materials to make them. Until a rumble felt into his office he didn't know was going on until his best friend and bodyguard named Gibs who has a enhanced strength quirk. Slammed the door opened to tell Scav about the situation.
"Boss we got a problem!!!" Gibs shouting right into his office.
"What's going on!?" Scav asking at the same time concerned .
"Something blew up the storage room boss!!!" Gibs said as Scav was angry to the point he Slammed his fist on the desk once more with a small crack.
A few minutes ago
Rey was checking around the storage room as he saw some C4 explosives all in one room as he thought to himself.
'Damn Idiots why did you mix your guns as well as your drugs you know you store your weapons in a separate room instead in one room you idiots' he said as he sets some C4s from the guns, bullets, drugs and flammable materials but before he blow up the storage room he then grabbed his backpack he bought in the surplus grabbing what he needs. Tools, Parts, materials, components, and even flammable materials for other guns for creating a new gun. As he left the room he has a detonator from the storage room and press the detenator in a farther enough distance as the C4 triggered a chain reaction of explosions from the guns, bullets, and flammable materials can be felt in the room.
Present day
After blowing up the room it was show time he then use his lethal grenades in the smart setting as he threw the grenade. The grenade has thrusters as it reads the enemies as some of them activated their quirks but it was too late as the grenade finds a target once it was close enough it explode and the grenade killed 4 villains as Rey comes out from the cover and began to shoot right towards the enemies infront. He then sees a villain using his water quirk but he was fast as he grabbed his pistol and shots the water villain but the Villains body just went through the water but Rey knew where his weak point that being his eyes. He switched to his rifle and get into cover and used the other magazine attached from the dual mag he added as he shoots right into the Villains eyes and one of the was shot and the villains was screaming in pain until a lethal grenade in the contact setting Ince it touches something it explodes immediately killing the water villain.
Rey continued on shooting down some villains there were approximately 25 or 30 villains and thugs inside the villains. He then killed more than enough villains until Rey saw Gibs and Scav infront of him as Scave activated his mutation quirk of a puma and Gibs activated his muscle enhancement. While Rey reloads a fresh magazine to his rifle as both of them standing in the opposite side of the room.
