With the Legendary Mechanic System, I transmigrated to Marvel Universe to be Dr. Zola’s assistant.

With Mechanical Force Analysis, I can learn every black technology.

Winter Soldier’s arm? I built a better one for you.

Iron Man’s armor? I already made it a decade earlier.

Doc Ock’s tentacles? I am the one who provided core technology.

Hulk’s mutation? Sorry, I was there and got hit by the radiation too.

As for a certain purple potato, can he collect all Infinity Stones?

……

However, I only had one simple ultimate dream. That is to go home…

There wasn't much to be said about the life of Akhil—at the age of 8, he lost his father at the hands of his most trusted business partner, who was also on his way to becoming the world's richest businessman.This left Akhil with no option but to use that traitor's daughters as a means to kill that man—a rather typical story where the main character takes revenge on his father's killer by making both of killer's daughters yandere.Of course, this wasn't a random fantasy story where he could just reach someone like the world's richest man—sitting at the highest point of the hierarchy—so the most he could do was act as the kind child he once was to those girls and slowly build trust and obsession, which finally bore fruit, and Akhil died.Indeed, how could he even be able to kill a man who possessed that amount of wealth?So, he died in front of both of those women—making sure that they saw him bloodied and dead.....The End.Or at least this was what should have happened.DING![ SUPREME YANDERE SYSTEM —Tada!! ]He opened his eyes inside the body of the Emperor of a ruined kingdom at the edge of the Human Zone—a group of three continents where humans lived while under constant attack from the threat of the 7 Demon Gods—and found himself in a sick body.A kingdom that was nearly collapsing due to corruption, the presence of holy light bearers—Heroes and Heroines—and a world filled with artifacts and fragments scattered around the bloodline—he who needed to lift the whole kingdom up again, hold the reign of a broken kingdom, and move forward.Now born as King Lysanderic Aleria Vandreat, he has only the support of his Supreme Yandere System.Oh, he awakened it too, but when did he?Read the Story...[: The main character is cruel, and there will be darkness in his actions, so enjoy the light in the first ten chapters (those are before he was reborn) and smile as you see the comedy and slight introductions to the characters. ][ Suggestion: If you don't like to know about Main character background, then skip starting 10 chapters. (Yes, the previous chapters are a prologue (not boring ones as they are important for understanding the main character and his future artifacts. Ahem.) ]

Jiang Xi, the warden of a mental asylum, transmigrated one day and became a girl from a farming village who had three engagements annulled and hanged herself three times.

Jiang Xi: That’s ridiculous!Jiang Xi was a psychic who could make predictions come true just by talking.

If she claimed that someone’s house would collapse, it would collapse the next day, even if it was structurally sound. In her previous life, her predictions were a little too real for her family.

They were spooked by her abilities and left her at that asylum.

She was unconcerned and adapted to life there like a duck to water. Though she managed to get promoted to warden after much difficulty, she suddenly transmigrated, and everything was suddenly the way it was before.

She studied her leaking house and sighed to herself.

Whatever. She would live life one day at a time, then.

When her mother clumsily ruined the family’s crops, Jiang Xi assured her: They would be fine tomorrow.Her mother wiped her tears and woke up the following day to check on the crops…

only to find that the ruined sprouts were budding! During the dry season, Jiang Xi’s father stared dolefully at the crops that looked like they were going to wither and die.

Jiang Xi simply pursed her lips and said: There will be a downpour soon.Jiang Xi’s father doubted her words.

But three days later, a downpour came, and he looked just like a happy child.Everyone in the village began to call Jiang Xi a lucky star, and the village head was willing to yield his position to her so that she would lead the village to riches. Bachelors proposed to her and came to her house with generous gifts even though they used to scorn her, but a tanned, muscular man with rough facial features stood in their way before they could reach the Jiangs’ house.

Zhao Xiping pointed at Jiang Xi and declared loudly: My wife! Mine!
