Everything starts with a system

As i woke up in an apartment building i live in, i remember that time, mom and dad protected with everything they had on a plane crash on our trip in jeju island... As it turned out we were gonna live on jeju island. But thats all memories now, it's already too late to change the past. I ate a piece of bread wore my blue uniform and grabbed another piece of bread and headed out, but before opening the door i closed my eyes said to myself "ok... Its your first time at a school, so act normal..." i opened the door and opened my eyes, but instead of seeing the rural streets i used to see. I'm at a coliseum, demons, ghosts, and all sorts of undead are the audience, and I'm at the stage, i looked everywhere and i saw bodies everywhere, and beasts in cages. Then i heard a loud voice

"we have a new challenger! Girls and men! demons and devils! Place your bets if this human will survive! Odds are 1:4!" then the audience booed at me, while they all booed at me a black window appeared in front of me, it says "welcome new user to the devil system, the devil system will help the user survive whilst in hell." then 3 boxes in the window appeared, it said "skill boxes" one was white, one was just a question mark, and one was black and show signs of a black aura, i opened the white and a skill appeared.

"weapon mastery(basic) learns all basic weapon arts"

then my mind was invaded, i could remember all sorts of forms, weapons, and uses. My mind felt like it was about to burst, it was so unbearable, i learned as i screamed "AHHHHHH" then the pain stopped then it seems i gained a new skill

"mind protection: slightly protects your mind from all sorts of damage, spells, and reduces pain received from learning (must learn for college students)(basic)"

i don't know why the last part is there but this is helpful for me.

Then i opened the question mark box and received a full set of leather armor and a stone sword, bow and arrows , and stone knife dropped out of nowhere. Its weird i know how i could use all these, i wore my armor, carried all the weapons a heavy bit I'll get used to it. Then i looked at the black box... I was scared of opening it, but if it means surviving hell, I'll take it! And i opened the box and it says "one of a kind skill unlocked

"corpse absorption: able to suck out a portion the attributes a corpse and make it your own(basic)"

then i looked at the other parts the system, there's a lucky wheel but it says i have to spend 10 demon coins to spin, and the price goes up 10 times each spin, but the price resets daily in hell time, then there was also a level up and attribute system, intelligence, strength, physical, and agility. My looking was disrupted by The announcer saying "the betting will close in 10...9...8...7...6...5-" before he continued i shouted out "I bet 1000 demon coins!" then audience went silent but the announcer just said "1000 demons coins has been added to the bet! If you win it will become 4000, but if you lose..." then i shouted out "i know!" i thought to myself "the goal was to survive meaning they will keep me alive to get the demon coins, even if i lose the fight, i will survive."

then the announcer said "betting will close in 10...9...8...7...6...54321!" and the beast cages opened at the same time i held my hand against the corpses and said "corpse, absorption!" then black lights started to appeared and entered my hand, and energy coursed into my body then the demon system popped saying "you leveled up x11" it also says attributes drastically increased "strength(basic:32) intelligence(basic:43) physical (basic:65) agility (basic:27)" as i absorbed the crowd as in awe as if seeing this for the first time.

Then the corpse absorption ability leveled up

"corpse absorption:absorbs half the corpse's abilities, can also skills, and attributes.(intermediate)"

the enemy appeared, two hounds of hell and 16 undead dogs, the undead dogs all ran to me while the hounds stood by being wary, the undead dogs seem so slow to me so i was able to quickly dispatch a dog with my sword, problem now is that I'm surrounded and I'm not fast enough to kill all of them in one blow, so i took the advantage and made a path.

After a few minutes of fighting the zombie dogs were defeated, and used corpse absorption and gained a skill called "four feet speed:increases movement speed when on moving on 4 limbs by 15%(basic)" and a unique skill "gluttony:increases an attribute depending on what you eat(basic)" then my attributes didn't increase much, but my agility attribute increased drastically strength(basic:40) intelligence (basic:45) physical (basic:69) agility (basic:58) i was feeling confident i can win this so i smiled menacingly and said "bring it!"
