Young Masters

Ning's cultivation base increased on its own and before he knew it, he had entered the Immortal realms. 

Strength-wise, it didn't make much difference for him however as his body was way stronger than what some measly Immortal realm could provide him.

The world Ning was currently in was known as the Four Jewels world. Most of its lands were covered in trees with leaves of one of 3 colors. Red, green, or yellow.

The continent with the reddest trees was called the Ruby continent, the one with shiny green leaves was called the Emerald continent, and the one with the yellow leaves was called the Amber continent.

Separating them was a vast body of water that had come to be known as the Sapphire seas.

Because it looked like a piece of four-colored jewelry from high in the sky, it had come to be known as the Four Jewels world.
