Yun Lan, a youth with a crippled meridian from Kunlun, and Ling Xi, a maiden branded an "omen of misfortune", face a dual predicament: bullying within their sect and the invasion of the extraterrestrial Star‑Devouring Clan. By chance, they awaken the ancient stellar beast, the Firmament Thunder Dragon. As memories of their tragic past‑life demise resurface, the two discover that dinosaurs are the guardians of Kyushu. With the aid of confidantes such as Yue Yao and Chi Fei, Yun Lan ignites his meridian power and awakens his true potential. He leads the horde of primeval beasts to break out of Kyushu, waging an ultimate showdown with their archenemies across the boundless starry sky, vowing to shatter fate and stay hand‑in‑hand for eternity.
