'Collect rewards.Open beginner pack and fit me with the knowledge inside the manual.' I start obtainig my powers using the system.

'I'll need to check how much the superheroes have progressed into their journey. I also need to make a name for myself as a popular music artist in order to have a popular public persona.But before that.' as these thoughts run through my mind a notification runs out.

"Holy hell!" I exclaim of loud, baffled by the messages.

'I just turned into a god damn calamity in an instant. I'm not a glasses kind of person though. I think I'll just give them to Leo.' I pondered.

'But still, this is good. I can basically go toe to toe with most heavy hitters already. I wonder how strong this system will make me. Now to see how this works.' I planned on using its abilities.

I start by raising my hand and pointing it at an empty glass kept on a counter. 'Now according to the manual I just have to....' I concentrate and try to control the cursed energy inside me and aim it try to shoot it out of my body. I try to do this for 10 minutes but nothing happens. 'Shit, nothing's happening. Ok, I gotta rethink this. I'm gonna imagine a fire.'

I start approaching the problem with a different method. I picture a flame where my heart is, and then cut a little bit of that flame out bringing it to my fingers. 'Now 0.1% power. Only trying to chip the glass.' I expel a tiny amount of cursed energy from my body.And then-

★CRASH★

Both the glass and the table it's on are ripped in two."Holy shit" I cry out, not having predicted the effect to be so great.

"Man, this is ridiculous. I can't even imagine what kind of damage I can cause if I use all my cursed energy to spam this attack constantly." I say out loud, startled by the unexpected force of my attack.

'It would be for the best if I don't expose my powers and learn to control them properly for now.' I decided.
