The starry sky.
It is something whose existence far surpasses that of humanity, the earth, and even the entire solar system.
And the planet where Lin Xing spent the first 20 years of his life has always been situated within this vast sea of stars.
He had long been accustomed to such a worldview.
Until he embarked on the path of the Immortal Dao, crossed the road of ascension, witnessed Kunlun Tianhe, and beheld a completely different world.
The current universe and the Kunlun Upper Realm are like two parallel lines, unrelated yet forcibly connected due to Kunlun's active devouring of other worlds.
This is how Lin Xing once perceived the modern universe and the Kunlun Upper Realm.
However, after obtaining the memories of numerous Ancient Immortals in the Tao Realm, especially those of an ancient immortal named Mingyang, his understanding of the world was broken once again.
It turns out that Kunlun was not initially composed of those endless mountains and vast heavenly rivers.
