A brief description of the manhua Secretly Cultivate For A Thousand Years:
Han Jue finds, after being resurrected in a cultivation world, that he can spend his life like a video game. He has the ability to reroll his cultivation potential and connate providence. Han Jue resolves to cultivate in a low-key manner in order to achieve longevity.
Generations of cultivators have become history over a thousand years. That is when the immortals begin to purge the mortal world. Han Jue can no longer hide and must take action. He then realizes that immortals aren’t all that powerful after all.
