When the Black Tiger Gang kicks down the courtyard door, Lin Yuan is a weak third-level Qi Condensation cultivator. Zhao Meng shatters his arm with a brutal punch, demanding a weekly protection fee. Unable to heal his wife with the Rank 8 Phoenix Marrow Pill due to her Soul Transformation seal, Lin Yuan swallows the divine pill himself. The medicine explodes inside him, instantly rebuilding his shattered arm and launching him to the peak of the Foundation Establishment realm. When Zhao Meng tries to kill Bai Qingyue in a blood-burning frenzy, Lin Yuan projects a defensive dome of qi. This protective act triggers a five-thousand-fold return, rewarding him with the Death Gaze spell. Lin Yuan locks eyes with Zhao Meng, unleashing black lightning that instantly obliterates the gang leader's soul. He then ruthlessly ruptures the dantians of the remaining lackeys, establishing his absolute dominance over the outer slums. This sudden display of immortal power leaves his wife in awe, but the threat of her curse remains. To find a way to heal her, Lin Yuan needs deeper resources and tools. He takes in her loyal cousin, Bai Chen, as a subordinate, tasking him with gathering an alchemy cauldron and mortal sentiments. By absorbing these sentiments, Lin Yuan gains a profound understanding of the Rain Dao's impartiality. He uses this insight to refine an ordinary iron sword into a crystalline Rain Blade, a weapon infused with a splinter of his Dao. When he tries to gift it to her, the system rejects the investment because her shattered meridians prevent her from claiming ownership. This failure proves he must fully restore her cultivation, setting the stage for a high-stakes trip into the inner city.

To acquire a proper instrument for his music-loving wife, Lin Yuan takes Bai Qingyue to the Premier Merchant Guild's seasonal auction, masking their identities with an illusion of spiritual mist. Using the massive wealth accumulated from system returns, Lin Yuan outbids the Heavenly Sound Pavilion, dropping an absurd one hundred thousand Spirit Stones on the Verdant Zither simply because his wife wanted it. He then spends three hundred thousand on a weathered painting, which his high comprehension reveals is a copy of the Mountain and River Screen containing hidden Dao traces. This massive spending draws the attention of Xu Tianyang, the heir of the powerful Xu Clan. When the clan's Core Formation protector, Uncle Yan, aggressively probes Lin Yuan with Divine Sense, the attack rebounds off Lin Yuan's Rain Dao disguise. Refusing to let the insult slide, Uncle Yan corners them outside the city, launching a devastating Great Shattering Print from the sky. Lin Yuan remains on the ground, drawing his newly forged Rain Blade. With a single upward swing, he slices the Core Formation attack in half and permanently cripples Uncle Yan. The terrified Xu Tianyang kowtows, offering his Soul Blood in submission. Lin Yuan rejects the blood, warning the heir that any further transgression will result in the absolute erasure of their clan. This clash proves Lin Yuan's lethality against Core Formation experts, but his attempt to decipher the painting fails because his cultivation is too low. The sheer volume of the painting's hidden Dao intent requires a much higher realm to absorb, leaving him with a sharp headache. Realizing his physical limits, Lin Yuan decides he must leave the safety of the slums to seek a remote mountain peak for his Core Formation breakthrough, leaving his wife under the protection of a spiritual barrier.

Lin Yuan retreats to a remote mountain peak to achieve his breakthrough, leaving Bai Chen to guard his wife. He tempers his body in a massive cauldron filled with giant elephant blood, consuming raw marrow under the guidance of a mysterious old man to forge an Ancient Beast Body. After seven days of meditation, he condenses his Golden Core and ascends to the Nascent Soul realm, manifesting a colossal spiritual projection that purifies the region. However, his absence allows the Xu Clan to launch a vengeful raid on his courtyard. Returning just in time, Lin Yuan faces the Xu Clan's powerhouses. Trapped within their Nine Heavens Thunder Prison, he does not panic. Instead, he uses his high comprehension to understand the true essence of the tribulation thunder, walking out of the prison completely unharmed. He captures the Xu Patriarch, Xu Canghai, in a lightning sphere and slaughters the remaining elders. To further consolidate his power, Lin Yuan enters the Mountain and River painting, meeting a mysterious monk who guides him to merge the destruction of Thunder with the impartiality of Rain. This fusion grants him the False Immortal Palmstrike, a technique that replicates a true immortal's descending might. Armed with these divine skills, Lin Yuan vows to give Bai Qingyue a proper wedding, which requires eliminating the remaining regional threats that loom over their peace. He realizes that as long as the major clans of Azure Cloud City believe they can target his family, he will never find true tranquility. This realization hardens his resolve to launch a systematic campaign of eradication against his enemies, setting up a brutal confrontation with the city's ruling factions.

Lin Yuan systematically dismantles his enemies to secure his wife's safety. He invades the Xu Clan estate, shattering their ancient defensive dome with a single strike and looting their vault to seize the Barrier Token, the key to the Barrier Realm. He then targets the wealthy Wang Clan, easily defeating Envoy Zhao Wuhen's Nascent Soul projection and forcing Patriarch Wang Tianze into submission. Finally, he returns to the Bai Clan estate, using his terrifying aura to age the cruel Elder Bai Mo to death as punishment for exiling Bai Qingyue. With the major clans neutralized, Lin Yuan relocates his wife to a magnificent estate in an emerald valley. He deploys the River of Years Pagoda, a primordial artifact that manipulates time, allowing him to cultivate for decades on the second floor while only a single day passes outside. While he refines his power, Bai Chen organizes a grand, proper wedding at the estate. Lin Yuan's rapid rise from a debtor to a Nascent Soul powerhouse secures their safety, but the ultimate challenge remains. He must use his newly acquired strength and the Barrier Token to enter the Barrier Realm, where he can find the ultimate means to break the Soul Transformation curse binding his beloved wife. The impending wedding serves as a brief moment of peace before he must venture into the dangerous starry domain to secure her complete recovery. To prepare for this dangerous journey, Lin Yuan utilizes the extreme time-dilation of the River of Years Pagoda, stripping to the waist on the second floor to absorb massive amounts of spiritual energy. His Nascent Soul hovers above him, refining the primordial forces of the universe. Outside the pagoda, the emerald valley estate is transformed by Bai Chen and a group of hired artisans. They decorate the grand main hall with red drapery and Azure Cloud-Bells, preparing for the proper wedding Lin Yuan promised. The juxtaposition of intense cultivation and domestic joy highlights Lin Yuan's unique path. He rejects the traditional, lonely road of immortality, choosing instead to bind his fate completely to his wife, setting up a final confrontation with cosmic forces.
