Right now, our MC just went through a tough trial. There were a total of 200+ people that gathered on the fifth floor. This is a resting/exchange area, so no one can die here. There is this rank SS statue carved that comes to life.
The statue explains that some God from another world summoned them (as well as others around the world). Humans are here for their desires/power basically. After explaining that, this old religious lady calls the statue a devil, then the statue says that she killed everyone on her floor, so she can't talk. Blah blah, she ends up dying by the statue.

All of her abilities are now open for grabs. The statues goes on to announce there will be a competition. From then on, every person randomly sees a number. One guy has 3, one has 12, while our MC has 22. The numbers equate to the number of opponents you must defeat to obtain that religious nut's power. Our MC just waits a few hours while everyone fights, then he goes up and shocks everyone. He starts to fight, then he breaks this dude's fingers one by one, and even when tis guy's HP is at 0, he doesn't die, since it's an exclusive competition right now. After beating/torturing a few people, he gets new skills such as torture and false evil (he had to act bad to scare away the competition basically)

Our MC was already #1 on the leaderboards but after this wicker performance, nobody dares to challenge him. Of course, the female lead knows he was only doing so to appear scary. He has made one trust worthy friend, Yang Suji. This girl is ranked 41st, but she does not die at all in a dungeon. That is her unique technique. She has OP regeneration basically. Even when this crazy berserk player who had the body/strength of like 15 f*cking goblins from drinking multiple bod enhancing potions, was smashing her to bits and pieces, slicing her body in half, she still managed to regenerate, so it's a scary good ability for her to have.
Our MC wins the competition after a few battles and gets an "escape ticket. This ticket allows him to escape from the sixth floor back to the resting/exchange area on the fifth floor for 12 hours, once he rips it. So this item is good.

From then on, the statue creates 7 plates and tells everyone to form teams of 7, the next floor will begin. Our MC pairs up with a set of twins (one girl rank 15, one little brother rank 145), his female friend, this crazy bit*h who is rank 3, and two others (one of them is secretly ranked 2 but we don't know yet)

So, sixth floor is like a huge cavern and at the edge, a huge drop with monsters at the bottom. His goal initially was to kill the other 5 with his female companion, and take all of their abilities to gain strength. Of course, all of that changes when he realizes that in order to pass the sixth floor, every one must use teamwork to advance past these dozens of shadow leeches at the bottom of the huge abyss hole (Rank SS). This change on the floor still results in multiple people out of the 200+ dying anyways, and sh*t gets awesome.

Also, the special ability he triggers at the start, and how he triggered it, make absolutely no sense, I lost a lot of respect for the author's storytelling ability when I saw it finally revealed later on.
In what way does enduring extreme self-mutilation have anything to do with being mentally suppressed by others, it doesn't, the author is an idiot.
His unique ability was supposed to be connected to what happened to him on the 1st level, but instead is used to magically give him a random, completely unrelated ability that completely counters generic future super side-kick's super powerful attack.
