MTL - Forty Millenniums of Cultivation - ~ Yesterday reappeared 31 future (fourth, one of the ends of the end!)

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.

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.

Vampire Hunter: Blood Rights, a highly acclaimed Virtual Reality Roleplaying Game. Lucian Silver was a normal guy who worked months to afford this game.

He raced home the day his VR unit arrived with the game. His enthusiasm was so great he spent 12 hours to make his character look similar to the NPC with the same name as him.

His choice would change his life forever!

Lucian Von Silver was a baron who had a fiancé in the game that would devolve into one of the early villains because of his jealous and how the protagonist would approach his fiancé Carmilla. This friction would eventually escalate until he died at the hands of Lance. Carmilla also died trying to block the sword aimed at his heart, showing her true feelings that were hidden all these years.

The moment Lucian created his character, lightning struck his apartment first, frying his computer. He thought to salvage his computer only for the second bolt to arc and strike him. Lucian died instantly.

Lucian awoke to find himself inside a strange mansion inside a casket. He has switched bodies with the former NPC Lucian Von Silver the baron. His blood boiled, although he was given a second shot at life. He was stuck inside a useless playboy who had nothing but his body as capital.

His fiancé was the beautiful woman named Carmilla. She struggled to show her emotions properly, which led to the strangely dense playboy and her to miss each other’s affection for each other.

Lucian felt despair. He wasn’t smart enough to survive with ease. Neither was he a martial artist with hidden powers. Just an unfortunate boy who failed to protect his sister and became a shut in.

A system appeared to save him from death.

[The Seduction System]

This system would help him grow out of his otaku personality. He’d gain a currency called Seduction Power [SP]. With this currency, he could buy various items, power-ups and bloodlines. But to gain this, he needed to seduce, molest, and have sex with women. He felt uplifted with a system aiding him. But he was a virgin with no female experience. What did he know about seduction? Could he really use this system?

Let us follow Lucian on his dark and thrilling erotic adventures. Will he kill the [Hero] Lance, or just flirt with his fiancée after discovering her deep affection?

But... Would the dark tides of fate and destiny allow him to be so relaxed simply by seducing women?

On the vast sea, Aokiji stopped a ship. After a great battle, Aokiji smiled helplessly, “Hey! Brother! Don’t waste your efforts! I am a natural-type ability! You can’t beat me of!”

Before the words were finished, a sword qi flashed across, freezing thousands of miles away, the frozen Qingzhi’s head crashed immediately, I was afraid that I ate a fake frozen fruit.

In the second half of the great route, Huang Yuan hummed incoherently, “Brother! You said you are faster than me! I’m so embarrassed!”

Before the words were finished, a figure stood on the flying sword and fled thousands of miles away in the blink of an eye, leaving behind a bewildered yellow ape fluttering in the wind.

Kaido: I am a blue dragon!

Someone: Sorry, my sword is also called Dragon Slayer!

 …

This is a sword story, but also a legendary story!

Of course, it is also a miracle that happened in One Piece.
