Jianjiantu

The great revenge has been avenged, but the old friend has not returned. All the blood debts of his family were paid off, and all he had left was a withered skeleton and an old sword. There was no more rival in the world, so he shouldered his sword and headed west. Above Kunlun, there is a road leading to the sky. People in the world follow the way of heaven to seek immortality, but he went against the way and only wanted his old friend to return. At the end of this road, there are immortals. Then... Keep walking.
