Wei Wuyin returns to the Scarlet Solaris Sect as a triumphant core disciple after eradicating the remnants of the Violet Moon Sect, yet he finds himself instantly targeted by hidden schemes and deadly assassination attempts. His butler's residence becomes a battlefield when two trained female assassins disguised as honorary disciples launch a surprise strike, forcing him to unleash his newly ascended Fourth Stage of Qi Condensation and his rare metal element qi to ruthlessly execute them both. This blatant attempt on his life is casually swept under the rug by corrupt elders allied with his rival, Jiu Lang, who seeks to suppress his meteoric rise. Rather than pleading for a futile investigation, Wei Wuyin maintains a cold indifference, biding his time as the high-stakes disciple competition begins. The arena becomes a theater of blatant favoritism and swift face-slapping when the neutral Core Elder Ji Yun, sensing Wei Wuyin's hidden potential and metal qi, openly shifts his allegiance to Wei Wuyin's faction, manipulating the very battlefield to empower his subordinates while actively suppressing and crushing the disciples of his rivals. Amidst this chaotic escalation, the core disciple challenge erupts in a horrific climax when Han Yu, a genius carrying a unique aquatic bloodline, unexpectedly detonates his own Heart of Qi in a suicidal explosion to cripple the veteran core disciple Mei Mei. This shocking reversal leaves the entire colosseum in absolute silence as Mei Mei lies broken and bloody, her status ruthlessly stripped away by the opportunistic Qu Gui, who challenges her crippled form to steal her coveted rank. As the dust settles on this brutal display of survival of the fittest, Elder Bai steps forward to announce a sudden change in the core competition, revealing that the disciples must now risk their very sanity to cultivate an ancient, volatile method known as the Haven Heart Qi Method inside the sacred Scarlet Dao Temple under the watchful eyes of a mysterious, all-powerful Godlord who threatens to cripple anyone who fails.

Inside the dark-grey halls of the Scarlet Dao Temple, the core disciples are introduced to the golden Haven Heart Monolith by the breathtakingly beautiful and terrifying Godlord Lin, who sets a brutal three-month deadline to cultivate a method that can forge a second Heart of Qi. The stakes are lethal, as those who fail to reach the first level will not only lose their core status but face immediate crippling by her hands, sparking intense fear and desperation among the competitors. Wei Wuyin cautiously retreats to a distant corner, analyzing the mnemonic of the first level, Mind Dissolution and Clone, while his rivals rashly plunge into deep meditation to win the Godlord's favor. The sheer danger of the ancient method is soon realized when the muscular giant Tao Gui loses control of his qi, expanding like a puffer fish before violently detonating into a horrific tempest of blood, bone, and raw energy that vaporizes He Long and leaves the other disciples severely wounded. Undeterred by the carnage, Wei Wuyin utilizes his exceptional comprehension and his previously refined pure yin energy to safely dissolve his mind and forge a perfect symmetrical mental clone, bypassing the fatal risks of spirit severing. His cultivation is briefly interrupted when the opportunistic Qu Gui attempts to murder him in his vulnerable state, only to be instantly executed by Godlord Lin for violating the trial's rules. Emerging from his deep meditation with a newly cloned mind and a fresh physical aura, Wei Wuyin successfully secures second place in the trial, while his rival Jiu Lang claims first place using a mysterious, high-level wood essence. As the trial concludes, the ruthless Godlord Lin mercilessly cripples the failed Shu Yang, leaving the core disciples depleted and the sect in utter chaos as Wei Wuyin prepares to claim his legendary rewards of elemental stones and six months in the coveted Yang Yore Fields.

Wei Wuyin enters the Yang Yore Fields for a six-month seclusion, utilizing his newly acquired violet lightning stones and the dense yang energy of the fields to birth volatile lightning qi and ascend to the Fifth Stage of Qi Condensation, the Yang Growth Phase. Upon exiting, he is immediately assigned to a high-stakes joint task force with the Sky Sword Sect and Aqua Echo Sect to investigate a massive string of mysterious disappearances across the country. During the mission, Wei Wuyin displays his overbearing dominance by effortlessly subduing a hostile rival disciple with his lightning movement and claiming a passionate kiss before the shocked eyes of his peers. However, his mission is cut short when a sudden, excruciating pain in his neck flares from his previous bite wound, accompanied by a mysterious voice that lures him deep into the forest where he encounters a pure black skeleton wearing a white robe. This enigmatic entity reveals that Wei Wuyin is now the Inheritor of Sin and warns him of an impending rank two calamity caused by Jiu Lang's greed in kidnapping an elven princess, which is destined to destroy the Scarlet Solaris Sect. To alter his grim fate, the skeleton abducts tens of thousands of people to shift the currents of destiny, transferring their accumulated positive karmic value to Wei Wuyin and elevating his karmic luck value to an astronomical number. Guided by this newfound heavenly fortune, Wei Wuyin stumbles upon the legendary Life Meadow Wood Essence, allowing him to easily birth rare wood qi and subsequently refine a pure Yin-Yang God Sphere given to him by a grateful elven lord. This dangerous refining process allows him to comprehend the fundamental world force and merge his yin and yang energies, bypassing centuries of cultivation to successfully ascend to the legendary Sixth Stage of Qi Condensation, the False Reality Phase, and become a true Mortal God.

Armed with his newly acquired Mortal God strength and a powerful Nascent Saber Soul named Element, Wei Wuyin sets out to investigate the mysterious disappearance of his former lover Mei Mei, who was taken by the legendary Helios Witch. His journey takes him through the Gaia State, where his astronomical karmic luck value guides him directly into a high-stakes conflict involving a beautiful thief who has stolen the City Lord's most precious treasures. After effortlessly decapitating the pursuing city commander with a single strike of his sublime qi, Wei Wuyin infiltrates the City Lord's palace, assassinating the newly ascended Mortal God and stealing a priceless piece of Mount Inferno's heart essence to birth high-level magma qi. As he attempts to escape the territory with the rescued thieves, he is confronted by the savage grand elder Gu Futu, who blockades the sky with a terrifying pressure and demands his immediate surrender. Refusing to negotiate, Wei Wuyin unleashes his full, monstrous cultivation base, combining his metal, lightning, wood, and magma energies into a single, world-crushing elemental fist that completely disintegrates the arrogant grand elder in a single, earth-shattering blow. This display of absolute power leaves the remaining elders paralyzed with fear, allowing Wei Wuyin to escape unchallenged and successfully sell his massive plunder for hundreds of essence stones in the prosperous Golden Milk City. However, his triumph is cut short when he discovers that the beautiful Godlord Lin and her companion have broken their spiritual oath and fled the city with his wagered magma essence, leaving him in a state of absolute fury as he swears to track them down and exact his cold vengeance.
