Unlimited Power - The Arcane Path - Chapter 8586

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.

A tree of 10,000 flowers, the world is the door.
The spells change a lot, but the hearts of the people are unchanged.
