In the "earth world" where spiritual energy is thin, young Lin Yue has been declared to have "extreme pulses" since he was a child and cannot draw energy into his body. However, he unexpectedly obtains a simple jade slip engraved with star patterns in the family's forbidden area. Hidden in the jade slips is the lost "Taichu Qi Refining Method", which can use the turbid air of the mortal world as a guide to reverse the broken pulse and embark on a heaven-defying path that is completely different from that of the monks in the world.
When he broke through the realm with his unique method, he discovered that the earthly world was just a corner of the vast mysterious realm, and the so-called "extreme pulse" was actually the seal of the ancient "Star Dao Body". As his cultivation deepened, Lin Yue became involved in sectarian strife and dynasty changes, and he also uncovered the thousand-year-old secret that the Xuan Territory has been coveted by "extraterrestrial demons". From a humble young man in a border town to a Taoist master who controls the stars and protects all realms, he uses the mortal world as his foundation and indomitable as his blade. On the road of enlightenment, he creates his own heaven-defying legend.
