My name is Leo Wallace, a PhD student in history, and I'm $137,542.89 in debt. In the darkest moment of my life, I lost my job because I criticized a tech giant called "Omni" online, and they "optimized" my employment. I thought my life was going to be a classic Chinese comedy, until an intruder popped into my head. He said his name was Franklin Roosevelt—yes, the one on the 10-cent coin. "Kid, stop criticizing online, it's useless." "Want to mess with them? I'll teach you." "Our first step is to become mayor." And so, I, a keyboard warrior who couldn't even find a job, embarked on a magical path to running for president under his guidance. Wait, Mr. President, are you sure this Second Bill of Rights... isn't really going to...

He traveled through a game world set in a magical remake of World War I, becoming a hapless imprisoned man in London. Luckily, he knew the plot well and possessed a cheat code that allowed him to replicate other people's abilities. Since fate had already condemned him to a life sentence, he decided to set the mountain on fire. "Miss Witch, how can you govern a country with these insects?" "Madam, you don't want your general husband to discover you're a spy for the Six Nations, do you?" "Go ahead, Princess, what are you hesitating about? Failure is treason, success is revolution!" "You ask what's on board? Nothing, just a few thousand guns... Arms smuggling? Don't slander me! I'm clearly supporting a just cause!" ... and so on. By establishing a secret organization, operating an underground industry, weaving a spy network, and collecting hardcore...

This is an era of infinite possibilities, steam and steel, gears and clockwork. Steam power and differential engines symbolize the infinite future of human civilization. However, no one noticed that under the haze of steam and in the shadow of steel, the dark, mysterious mystery has never left. And a traveler from a foreign land will unveil the mysterious veil in this turbulent, free and dreamy world, and write his own history and legend

Tiandao Siming traveled to a different dimension TV series called "Stars".

He was bound to the "popularity system", and as long as he gained enough popularity, he could get everything he wanted.

Therefore, soon, a super popular villain with outstanding appearance, super strength and likable personality appeared.

[Star Eclipse Eye: can observe the "energy flow" of itself and the target 100%, so as to predict the opponent's next move 1 second in advance in battle]

[Vector control: can control the motion vector of the object touched (such as the impact direction of the attack, the flow path of energy)]

[Overclocking calculation: the brain enters the "overclocking state", and can simulate tens of thousands of deduction results at the same time to find a winning solution]

Super high popularity brings super strong strength, and super strong strength brings super high popularity.

A few years later, relying on his own "talent" and "hard work", Tiandao Siming, who "hardly" stood at the top of the stars, gave an MVP settlement speech that matched his personality.

"Rules? They are shackles for the weak. I, the God of Destiny, only follow the rules in my heart."

"Don't go out after dark. There have been a lot of fake people showing up in the city lately," my brother—the infamous Rainy Night Butcher—warned with a serious expression.

"Your brother's right," Mom—the Original Fake Person—nodded with concern.

"Bro, can you pick me up after school? I’m a little scared." My little sister blinked at him. But in truth, she was an A-Rank Hero from the Hero Association.

"Your brother’s just recovered from a serious illness. Let him rest at home, I’ll go get you." My older sister, the Captain of the Night Watch from the Special Operations Bureau, took on the task.

Qiao Qingshan, who knew all his family’s identities, said nothing—he just kept fiddling with his phone.

And so, my peaceful daily life began...

"Due to the recent outbreak of fake person incidents, we interrupt this program to bring you an emergency notice from the Special Operations Bureau."

1. Fake people often take over the bodies of those who’ve just recovered from serious illnesses by using a technique called 'soul possession.' If someone who has just recovered begins acting strangely, pay close attention.

2. There are no such things as 'transmigrators' in this world. Anyone claiming to be a 'transmigrator' can be immediately classified as a fake person.

3. Fake people who claim to be 'transmigrators' are considered extremely dangerous. Do not trust any information they provide, including but not limited to emotional expressions, identity claims, or cries for help.

Faced with the suspicious looks from his family, Qiao Qingshan could only sigh.

Alright then... so much for my peaceful daily life.

"She was originally a demon. How could she be led evil after meeting a human like me? Those critics always say some ridiculous things."

In 1798, during an interview with a reporter, Cardinal Ranchi was asked about his past with the exiled princess of the last descendant of the demon clan, as well as the recent signs of the demon clan’s recovery. He said:

"I have made too many efforts to safeguard world peace. I am convinced that under her leadership, there will be no chance of the demons returning to the country."

…

In the winter of 1802, the demons successfully restored their country.
