Solo Max-Level Newbie
Read ch. 173 The MC is a 27 year old guy who played a game for 11 years just to finish it. Right after He finished the game, by clearing the 50th floor of a Tower, an upgrade of the game was announced to him. After 12 hours passed the Tower appeared in the real world thus the game became a reality. The MC chose the solo approach and he's also OP (and greedy, calm, little psychopathic).
Resurrection of the Catastrophic Hero
Read ch. 29 It takes place on Earth that went downhill due to sudden apperiance of monsters and some kind of a weird version of a tower. 12 people got blessed by Zodiac Gods (like Cancer, Leo, and so on) and thus getting superpowers. However, one dude got powers as well even without the blessing - that's the MC. The MC is quite OP (maybe stronger than the 12 people combined) but he's guite... simple (doesn't want to think, eats a lot and fights head on without a plan). The MC is also "humble" (Meaning He didn't become high on power as others, except one of the 12 - Hugo, did). Anyway tgese 13 people fought the monsters and climbed the Tower until they got to the boss room. Hugo was dealing with monsters outside and the MC And others Walker in, the 11 "Heroes" Ford, leasing the MC behind. The MC defeated the boss And right after that someone stabbed him in the back, He survived though And returned after 20 years of fighting inside the Tower - all on his own. He also became a God himself (it seems). Now that he's back he's taking steps towards his revenge.
The World After The Fall
Read ch. 37 The Story takes place on Earth. One day the Tower appears and some people are chosen as walkers, aka the Oneš to climb the Tower. During the climb, there appear returning stones and most of the walkers use it in order to go back to the past, however the present doesn't change. The MC is an OP "stabbing" maniac. In the end je cleared this Tower just to find out, that he's cleared the tutorial, Earth is a planet in some spare dimensions that is connected to the roots of the World tree, he's in a coma and the Tower is a nightmare that he can't leave cuz the owner of this tower is a demon who wants a promotion... So he decided not to confirm the clear of the Tower, kill the demon and escape the Tower through the roof... Just to end up in Chaos, which is somewhere above the roots but on the lowest point of the World tree... and is also basically a purgatory (space for dead to gather). OH, and there are 12 monarchs, basically autorative figures as Gods, who are interested in the MC, especially the Dark Monarch.
