It's Been Three Hundred Years Since I Woke Up

In the Tianli year, the martial arts of the human race flourished, and the martial arts dominated the world. Once the sky falls, the corpses of gods and demons fall into the mortal world with their blood, birds and beasts mutate and become demons, and the world becomes a purgatory. At the time of crisis, the human race awakened to the divine essence, and the ancient martial arts that had been passed down for thousands of years fell into decline. In the years when demons and chaos were rampant, Gu Qianmo burned all the evil flowers in his heart to save his loved ones, and died in battle under the withered tung trees on the cliff. Three hundred and sixty years passed, and the old friend with white hair returned to the world. His home was in ruins, his old friends were gone, and the whole world was no longer what he remembered.
