Time travelling from the majestic era after the Recuperation of Reiki, he became Kimura Kazuki, a 16-year-old high school student in Japan, one year before the Reiki Recuperation.

Tentatively, he set out to hone himself to the bone, burning candles at both ends to stockpile resources in preparation for the imminent Recuperation of Reiki. His goal was to be many steps ahead of all humanity when the time comes.

However, it seemed like fate had decided to play a cruel trick on him.

One year later, the Recuperation of Reiki… did not happen as expected.

Shao Xuan joins a friend in his expedition to a recently discovered archaeological cave. After he picks up an ordinary looking stone he is teleported to a different world and wakes up in the body of a small orphan child. The world he is in now is still in its stone age with primitive tools made of stone and the ways of the people are savage. Savage isn’t the only thing special about the people though, because they have superhuman strength, jump higher than trees and punch stones. In short, they are able to cultivate their bodies. Despite all this, it is a real struggle to survive because of the scarcity of food. Together with Caesar, his pet wolf, he tries to survive in this cruel world.

Long Chen, a crippled youth who cannot cultivate, is constantly targeted and bullied by his fellow noble heirs. After a particularly vicious beating, he wakes up and realizes a Pill God’s soul has somehow merged with him, giving him some additional memories. Within those memories is the mysterious Nine Star Hegemon Body Art, a cultivation technique that even he can train in, but whose secrets and origin are still a mystery to him. Relying on his improved instincts as he finally begins to cultivate, he realizes a huge conspiracy is underfoot within the Phoenix Cry Empire, one involving his father, members of the imperial family, and even the Emperor himself.
