MTL - Morning of Swordsman Tower - Chapter 15

You were taken to another world by a ghost ship.

You are uneasy.

There are ravings in your ears, accompanied by weird bgm, you sing and dance rap in pain.

You pick up a magic lamp, and after making a wish, it says it’s just a lamp.

You are impoverished, and you swear by your personality that you made a deal with the devil, and in the end the devil was sold by you.

You are walking on the road, and you meet a down-and-out princess who is begging for a child with a lot of money, and you yell “Mom~” in the street out of the principle of helping others

In the middle of the night, you flipped through the pages of “Ten Thousand and One Nights” in your hand, and your excitement became stronger and stronger…

Eren Idril died as an old, decrepit, and piss-poor adventurer by the maws of a D-Rank monster. He had a lot of unfulfilled dreams and desires that couldn't see the light of the day after the light in his own eyes died down.

But fortunately for him and unfortunately for the world, that wasn't his end. Eren was somehow dived back in time when he was a mere teen, attending Lionheart Academy for adventurers.

When life gives him a second chance, Eren decides to exploit it to its fullest. Experience his vile deeds as he partakes in them without feeling the slightest bit of hesitation.

A chance to change, to challenge destiny, making dreams a reality, and live a legend! A regular man gains a system that allows him to turn into a fish!

When she reborn, she finally understood; men can never be relied on.
That being the case, she can only rely on herself to win, that
splendid brilliance she yearned for, in this lifetime.

To my scheming Stepmother and ruthless sister, I will
destroy all your backings, pull off your wings, and step on your
arrogance! As for Grandmother whom speaks kindly but has a snake-like heart,
and a father who is hypocritical and exploits advantages; I will tear
off your pretense and cut off your hope! Let’s see how you can still
scheme against me!

Witness her splendid fight against her stepmother, punish scum men,
and create havoc in the imperial court, as she soars with the wind and
rises above the water!

But as for that man who still stands! How dare he play with my heart?
