Tensei Shitara Slime Datta Ken (WN) - Chapter 389

At the beginning of the universe, there was only chaos. Chaos gave birth to a world, accumulating into Black and White and the five elements (also known as the Origin Elements), creating the world's laws and the order of heaven and earth.

This world was called the Origin world, where the Original beings born out of chaos reigned. They created orders, creatures, and numerous worlds where they reigned as Supreme beings until a calamity befell them and destroyed the Original world alongside numerous worlds.

Two billion years have passed since then. In a small world somewhere, a baby was born carrying an unusual past.

The mysterious boy Ling Chen is saved by a little girl as he lay on the street dying. Years later, he strikes a deal to save this savior-turned sister and enters the virtual world. In a future Earth where advanced warfare has forced nations to settle issues virtually or else suffer the consequences, Ling Chen bursts into the scene and goes from unknown to legend. Yet all is not as it seems, for Ling Chen has a dark past, and there is a greater mystery at hand behind this virtual world.

To save his terminally ill little sister, Ling Chen enters the newly released virtual game world and joins a small gaming studio comprising entirely of women. From now on walking upon his path towards the pinnacle. An ancient, evil item almost forgotten by history, the “Lunar Scourge” helps forge his unsurpassable legend, and causes him to unknowingly step upon a path that is destined to be punished by the heavens, the way of the Shura.

Cthulhu Gonfalon is a story about a man who woke up in another world. After a drink over his loss in a game, Sui Xiong ended up in the middle of the sea. Surprisingly, he now found out he no longer existed in a human shape but in a spirit state without any flesh. In order to survive and find a way to return to Earth, he then searched for a body to accommodate his spirit. After several confrontations with some creatures under the sea, he decided to settle for a jellyfish flesh. This Jellyfish was extraordinarily huge. With its tentacles, it caught others’ spirits to nurture its own power. In this world, Sui Xiong wasn’t only matchlessly powerful but he also had an ability to cast magic. With this gifted ability and combined with his knowledge from the civilized world on Earth, he could help a deceased person resurrect, change a person’s look, and do tons of other crazy things that he didn’t know.

As his journey to discover this world went on, he encountered many bizarre and mystic creatures along the way, who were Gods, Humans, Devil Beasts, Giant Dragons and lots of other undetermined organisms. Some of them might insanely worship him, while others hated him. Some might become his enemies. Some might end up becoming his teammates in the end. From a gamer on Earth to here, he became a God (even he himself could not verify this yet), had his own religion and even a church with a Holy Land to fight for justice.

What kind of world is this? What kind of existences might live in this world? What kind of secret this world owns? Can Sui Xiong return to Earth?

Keep on following the story to find out the answers for those questions.
