[Fantasy premise + mastermind behind the scenes + the fourth catastrophe]

I was transported to a world of swords and magic. While others start with divine artifacts, I start with a dilapidated internet cafe.

Lin Che thought he was doomed, but unexpectedly activated the [Super Dimension Internet Cafe System]!

From that moment on, the art style of this world completely went astray!

What? A Templar Knight who had painstakingly cultivated his fighting spirit was beaten to a pulp by an unknown nobody who spent his days "suffering" in internet cafes?

"Sorry, I've died ten thousand times in Dark Souls. Your sword is too slow!"

What? The Empire's strongest mage force was routed by a group of orc warriors shouting "For the Horde!"

"Hey buddy, ever heard of World of Warcraft? Those who play tactics are all cunning!"

When the proud elf princess is hopelessly addicted to Stardew Valley, when the staid dwarf king becomes a construction maniac in Minecraft, when the strongest people across the continent are fighting tooth and nail for a single internet access spot...

As the sole GM, Lin Che sat in the boss's chair, holding the keyboard and mouse, calmly issuing world quests.

"The new dungeon, [Hell Dragon Extermination Battle], is now open! First kill reward: artifact; login fee doubled!"

"Warning! The Pope has been found to have exploited a bug and has been permanently banned!"

The old world's royalty, nobility, and church regarded him as the greatest heretic and wanted to get rid of him as soon as possible.

The common heroes and kings of the new world regard him as the only true god and are willing to offer their faith to him!

When magic meets machine gunners, when dragons meet apocalypse tanks, when everything in the game becomes reality.

I, Lin Che, consider internet cafes my divine kingdom, and gamers my believers; I am the sole true god who has ascended to a new world.

Good news: Qiao Zhi successfully traveled to MC Minecraft and became Steve. Bad news: Starting on an empty island, there's only a grass block underfoot. Just as Qiao Zhi was enjoying his prison sentence, a space portal appeared before him. Giant: Erwin, survive, and I'll tell you the truth. Parasyte: Someone used their powers to gain the heart of a long-time crush, but I hope you'll dispose of the body properly. Demon Slayer: Muzan, don't be afraid, I'll heal you right away. Hunter x Hunter: Meruelu, for an ant, you're too arrogant. Bleach: Aizen, when did you start to think I didn't use Kyoka Suigetsu? Drawing swords, accelerating torches, better cutting boards, equal exchange, endless greed... God gradually regains his authority... In the anime, perhaps...

[All-people job transfer + summoning flow + invincibility + cool and refreshing + funny + entries + no emotional drama]

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!"
