Lin Haoyu travels through time and space to become a villain in a book. When he completes his final role-playing task, he lands on his left foot first, so the system forces him to repeat the story. Unbeknownst to him, this time the heroine can actually hear his thoughts. [Holy crap! You actually agreed to be my girlfriend?] [What are you doing? Why are you throwing yourself at me? Where's your female dignity?] Lin Haoyu is stunned. Why are these heroines so off-kilter?

I want to write a book. First, I need an interesting and handsome protagonist to connect with the reader. Then, one or two beautiful, lovely girls... maybe three or four would be nice too. With a boy and a girl, it's only natural to add some romance, some ambiguity, some heart-throbs, a layer of milk and honey, a touch of bitterness and astringency, all mixed together... It looks delicious. Then, add a flirty narrator and set it up as a system. Finally, to make the book taste even better, I need to add more sugar. I open the sugar jar, and then, with a slip of my hand, I pour the whole thing in... Damn, isn't that too sweet? I hurriedly pour in some more "Book of Songs," some Shura scenes, some life philosophy... Finally, this is the book... I think it tastes pretty good.

Ten thousand races invaded, and everyone changed their jobs.

Every human being has an opportunity to awaken his or her profession, pursue the pinnacle, and defend the country.

Lin Ze changed his job and became an S-class demon summoner, but was laughed at by everyone.

Because contracting a demon consumes one's own lifespan, it is basically useless.

But Lin Ze smiled without saying anything, because he had awakened a system that could increase his lifespan by killing.

Kill a chicken and your lifespan increases by 1 day.

Kill a Skaven soldier and increase your lifespan by 10 days.

After killing a Fire Spider, lifespan increases by 12,000 days.

So, there are all kinds of awesome demons for you to choose from!

Consume 10 years of life, summon hellhounds, and launch a shadow raid!

Consume 100 years of your lifespan, summon the Flame Demon General, and burn everything!

Consume 150 years of your life to summon the Succubus Queen, who is so charming that she captivates everyone!

I am a legion by myself!

Not only that, completing system tasks can also draw various entries and apply them to yourself and the devil:

I won the soul link, and it just reached level 5 with attributes exceeding ten thousand!

If you draw the lucky number, you will be immune to all negative states!

If you draw the magic of heaven and earth, your size and ability will be expanded 100 times!

Soon after, the myriad races that had been eyeing the human race covetously led their armies to invade.

Alien lord: "Hehehe, I have been planning this for a hundred years, and all humans must die!"

Alien soldier: "Report to the king, our army has collapsed, and the enemy looks more like a villain than us!"

Elves, dwarves, halflings? Where does this come from?

Mage, priest, paladin? Supernatural powers? Interesting...

Spellcasting talent detected? Does that mean I can become a noble mage?

"No, buddy, what do you mean by assigned to the Geotechnical and Natural Sciences School?"

"Damn it! How come I'm assigned to civil engineering after arriving in another world?"

…

"Master Mage Gerudo, what do you think of the famous and legendary graduate of your magic academy?"

Many years later, when faced with an interview, the elderly magician remained silent for a long time.

"Nothing with a mage's soul!"

Traveling through the world of martial arts, Su Yu obtained the role of Gilgamesh, nicknamed "Golden Flash," the Hero King of the Type-Moon world. He established a mythical land, the master of the Golden City, and summoned heroes like Artoria and Joan of Arc to serve him. Just as Su Yu was about to establish an immortal dynasty, the Golden List of the Great Dao was revealed! A list of heroes from around the world was compiled, revealing the many heroes of the Golden City, and Su Yu was at the top! Shocking the world! It turns out that there really is an ancient king in this world, two-thirds divine and one-third human! His royal treasury contains the most ancient treasures in human history.

Giant dragons roared in the sky, golden behemoths ran across the earth, giant Krakens stirred up thousands of meters of sea water, and the ancient hundred-eyed giant slowly poked its mountain-like head out of the cave.

Fantasy creatures are rampant on the continent.

Lin Yan came to this vast alien continent, looked at the weak magicians all over the world, and then looked at the giant dragon next to him that was knocked unconscious by him accidentally, and felt a little hesitant.

Why do I feel like I'm different from everyone else? I'm a little bit stronger...

Flashing graves. Just after crossing over to a new world, it was destroyed, leaving Su Ye as its last human. Luckily, a chat group arrived, and upon signing in for the first time, he was given a 'Cocoon of the End', forever binding himself to this world. The stronger the civilization, the greater its power. But... there are no humans left in this world. So, my friends in the group, are you planning to immigrate? Free houses, land, and superpowers! You don't want the cursed child? Take it!

A new round of Great Collapse is about to begin. Let's interview the first few Herrschers to defect from the "Honkai" camp and see what they have to say. Herrscher of Reason (Bronya): That means I'm the First Herrscher! Herrscher of Lightning (Raiden Mei): Because I'm Raiden Mei! Herrscher of Wind (Wendy) and Herrscher of Ice (Anna): Say, we will protect everything that is destined! Herrscher of Void (Kiana): Restoring the glory of the Herrschers is our duty! And finally, the Finale (the protagonist): Awakening is a success!

The Immortal Emperor has returned, his cultivation intact, invincible and overwhelming. In his previous life, he was cowardly and incompetent, watching his family fall apart, his mother die prematurely from overwork, and his sister suffer bullying, all while he was powerless to do anything. Those who once despised and insulted him now stand tall, a height he needs to look up to. In this life, now that he has returned, his cultivation intact, all of this will be rewritten. He will personally atone for those regrets and settle those grudges.
