Let us see how a small otaku uses power and strategy step by step starting from an ordinary human to writing a legend as the devil’s greatest son-in-law.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

Forcefully brought over from the modern world to an alternate world, Wang Chong felt detached and lived his life aimlessly.

However, when calamity struck and he saw his family and everything he cared for being torn apart, he felt regret.

Thus, he stood up and eventually became the Grand Marshal of the Central Plains, leading an army against those who seek to destroy all he cherished.

Yet, despite all his efforts, it was already too late to reverse destiny.

But before his death, a shooting star, the same one which brought him to this world, appeared before him, and he was given another chance to undo his regrets.

(Pirate + meme + invincible, the identity of the protagonist is navy + pirate + revolutionary army, mastering various elemental skills of fire, thunder and dark ice)

Yang Ming travels to the world of One Piece and gets the meme-making lottery system. /Anime/Classic lines of game characters, you can get a random ability/item, and even summon the character to appear!

“Work less and get more, and get something for nothing, that is my ideal!” “Congratulations to the host for speaking the classic lines under one person, and obtaining one of the eight miracles, Saint Thief!”

“Do you want to dance too?” “Congratulations to the host for speaking the classic lines of Naruto and getting Sharingan!”

“I want this day to never cover my eyes, and this place to never bury my heart!” “Congratulations to the host for getting the golden cudgel!”

It’s cool to make memes for a while, and it’s always fun to make memes all the time. As long as I make memes fast enough, no one can overtake me.
