In the future high martial arts world "Sky Star", martial arts and technology are combined, humans explore the starry sky and establish a splendid martial arts civilization. However, mysterious "space-time rifts" occur frequently all over the world, from which alien beasts and unknown energy pour out, which are regarded as the source of disaster. The protagonist, Shen Ying, is a spiritual master who has been lonely since childhood due to a strange destiny (Tiansha Lone Star). When he was about to die in a rift explosion, he awakened a unique golden finger - a "shadow" with independent consciousness and evolutionary ability. This shadow can not only perfectly copy and optimize any martial arts he sees, but it can also swallow the "chaos energy" in the rift to evolve infinitely, and even split into sub-shadows with independent combat capabilities. Shen Ying rose rapidly with the power of shadow, but as he investigated the truth of the rift in depth, he gradually discovered that the rift was not a natural phenomenon, but a "civilization screening program" set by an ancient civilization for current humans. His destiny as the Lone Star of Heavenly Evil turned out to be the "error mark" produced after the failure of this program, making him the natural enemy of all "screeners" and the unconscious "gatekeeper" of human civilization. He must lead his partners to uncover the mists of history, break the cage of fate, and lead human martial arts civilization to complete the ultimate "dimension ascension" in the competition between various forces (including consortiums that exploit the rift, government agencies seeking the truth, and mysterious beings from the other side of the rift).
