The spiritual qi revival was about to begin. To protect his descendants, he left seclusion to seek them out. His family was cultivating immortality, but his descendants livestreamed it, causing a worldwide sensation. Powerful figures from all walks of life came to visit, and the major sects of the cultivation world came to challenge him. With no choice, he casually stepped in, dealt with a few unreasonable sect leaders, casually wiped out several demon kings and devil kings, and unified Earth's cultivation world.
When the spiritual qi revival began, he taught his grandson a simple Qi cultivation method. Within a year, his grandson broke through to the Golden Core stage; in two years, he reached the late Nascent Soul stage; in three years, he ascended to the Deity Transformation stage; and in the fourth year, he entered the Great Ascension stage. That's how powerful I am after cultivating for a hundred thousand years.
Powerhouses from other planes came to challenge him, so he sent his grandson to deal with them. When his grandson couldn't win, the old ancestor stepped in, shattered the planar barrier with a single finger, entered the plane, and fought his way through seven times in and seven times out. In the end, he advanced to the Golden Immortal realm and unified the cultivation world across the planes.
