A strange man kills you

If you don't have a basement, you do now. You hear a noise in the basement and decide to check it out. You look around and see nothing but then you catch a silver glint, a knife. It appears to be floating in air but you realize that there is a strange man holding it. He throws the knife at you. You dodge. The man takes out 2 revolvers each with 1 homing bullet in them. You hide behind a wall and they lodge into it. The man pulls out a large pole and swings it at you with ease. He knocks you unconscious. You awake in a bed, restrained by 3 adamantium-steel alloy straps made bendable with kevlar. The man is nearby. He pulls a large lever and a pole comes out of the ground with a strange device attached to it. You decide to look around and realise that you're in the strange man's hideout, which is massive. He fiddles with the device for a second then finally presses a button. A thin pole comes out, then a circle with another pole and then a small knife. He guides the pole towards your chest. He first injects you with a shot that will make you temporarily invincible. The knife cuts through your chest. The pain is already unbearable. You scream very loudly but the strange man reaches down your throat with some large wire cutters and rips out your tongue. He then proceeds to slice off your vocal cords and puts them in a pot along with the tongue. He goes back over to your chest and takes a saw. He saws your ribcage open and places all of the bones into the pot. You can feel your internal organs being ripped out by the man. He grabs your beating heart and cuts through the arteries and veins. Blood is fountaining out of your body. When he is done removing the organs, he starts to mix the things in the pot together with the acid from your stomach. It makes a strange liquid and he drinks all of it. Suddenly, the strange man trips on a rock and falls on another lever that releases the restraints. You get up and feel no pain and your body surges with adreneline and rage. You rush at the strange man. He pierces your back with a spear but it does nothing to slow you down. You pick up the spear and are going to stab him and pay him back for everything, every time he killed you, every time he appeared, when he cut you open. You're life has been a living nightmare and all has been ruined because of this man. You feel like you will finally put an end to him once and for all, the revenge is so sweet. You know you will kill him when he claps his hands. You freeze and collapse on the floor and feel completely drained of all energy. The man says the first words he ever spoke.
"You can't beat me."
He throws a purple dagger and it disintegrates your body and you end up in your bed. You are relieved and think it was just a nightmare. But your skin is oddly red. Your veins erupt and blood spews out. The strange man has destroyed everything when you walk outside. You are the last human alive, everything has been destroyed and you will die a painful and long death.
