Special Forces Soldier Yang Zilun (codenamed "Savage") traveled through the Jin Dynasty during an S-level mission and became a scout. He relied on modern firearms, special equipment and tactics to fight against cold weapon armies and low-level practitioners, destroy the demon clan's "devil fetus" conspiracy, and get to know Xueer. Knowing that Xue'er is the container of the "Ancient Road to the Galaxy" on the way home, Shangguan Xibing, the Immortal Lord of the Cultivation Alliance, wants to seize the key. Yang Zilun develops rune weapons and completes the ten thousand-year foundation construction. He discovers that he is a descendant of the founder of the Thousand Star Sect, and Xue'er is the reincarnation of his wife. The two of them merged their power, and when pursued by the Immortal Lord and the "Hive Consciousness", they blasted their way home at the cost of shattering their energy core, and returned with serious injuries.
