When one had nothing to worry about, climbing to the peak of cultivation became the sole lifelong aspiration.
Then, they enter seclusion once again.
Once, twice, thrice, and so on. In this way, even the strongest individuals undergo a shift in mentality, until ultimately reaching the state of Great Oblivion.
When their cultivation level reached its peak, they sat in the Great Path Ocean and looked at the Human World and the Immortal Plane. They observed the world's affairs, the white clouds, the mulberry fields, and the disputes of the Human World. It was just a snap of the fingers. Thousands of years later, the country, civilization, and glory will all cease to exist or perhaps exist in a different form.
Li Qingshan also had such an experience during his 15,000 years of closed-door cultivation.
