#JELLYFISH
One day without warning, a meteorite named Dickinson crashed into the depths of the ocean.
The radiation produced caused jellyfish to become isomorphic to humans, and a month later, the world's first jellyfish synchronists appeared.
No one knew at that time that as long as there is contact with a jellyfish, the body and will will be tightly intertwined with it. This process is called attunement.
After synchronization, humans will live in symbiosis with jellyfish and can freely change forms, but they will need a lot of fresh water.
The first batch of synchronizers were untrained and undefended. They just touched accidentally. The moment they synchronized, the human will was swallowed up by the jellyfish's will and became an abandoned corpse.
A hundred years later, the "Pre-Jellyfish Era" ended and the "Jellyfish Era" began, marking the world being ruled by the Jellyfish Synchronizers.
An abandoned jellyfish, codenamed Amelia, suddenly appeared in the waters of the Issa Sea. After testing, it was found to be a new species created by the King's Mane Jellyfish assimilating a large number of Steel Bone Jellyfish, and its combat power reached S level.
There has never been a synchronizer whose combat power level has reached S before. This attracted worldwide attention.
Because the Issa Sea is located between the Ostra Agreement Country and the Chaohai Country, personnel from each of the two countries temporarily formed a team to investigate.
Concept: The sea is like a shrine for sin, containing all the tragedies caused by power.
