Sandstorm

John sucked in a deep breath as he heard his fathers words. Everything had started in this basement chamber when he had discovered the mysterious sphere.

Upon touching it, it appeared inside of him as a second dantian, and the rest of his journey was set into motion. It was the thing that broke his curse of not being able to cultivate, and was the thing that changed his fate forever. If not for the sphere, John knew he would most likely still be unable to cultivate, and his clan would have been wiped out.

It was not unreasonable to say that the sphere was one of the things that saved his clan from destruction.

He had asked his father the day after obtaining the sphere what it was, but Barden had only said he would explain things when John was older. It appeared that the time for those explanations had come, and John was waiting for each word on bated breath to learn the truth about it.
