Cultivation: You're a Hundred Years Old, and You're Telling Me the System Just Activated?

After transmigrating for eighty years, with his life span nearly exhausted, Gu Changqing was abandoned by his former cultivation partner.

He sat alone in a bamboo hut on the back mountain, lasting until his hundredth birthday, when his golden finger finally arrived!

[Ding! Your hundredth birthday has arrived. The Hundredfold Return System is activated!]

[A century of arduous cultivation is returned a hundredfold. You have broken through to the late Golden Core stage! From now on, every day of cultivation will also earn you a hundredfold return!]

Just then, the Demon Sect launches an all-out assault on the mountain. The protective formation breaks, the sect master lies near death, drenched in blood, and Qingyun Sect teeters on the brink of destruction!

On that day, the centenarian on the back mountain, with his life span nearly exhausted, opens his door. With a flick of his finger, he slays a Golden Core cultivator; with one sword, he sweeps away the demonic sect!

After surviving the calamity, the sect master leads all the disciples to kneel along the mountain path:

"We pay our respects to the Supreme Ancestor! We beg you to take command and restore our sect!"
