Ordinary boy Su Chen is turned away from Qingyun Sect because of his impure spiritual roots. But thanks to a family heirloom jade pendant called the Chaos Mirror, he unexpectedly becomes an outer sect disciple, earning the ridicule of everyone as a “gift-giving freeloader.” Little do they know that this ancient artifact conceals a secret: it can purify spiritual energy and analyze cultivation techniques, helping him improve by leaps and bounds where no one can see.
At the sect’s small-scale tournament, Su Chen makes a stunning debut and slaps down everyone who looked down on him. During an expedition into a secret realm, he saves Lin Qingqing, the righteous sect’s shining jewel and a personal disciple of the Qingyun Sect Master, winning her favor. But he also mistakenly stumbles into the sinister Netherworld Valley and becomes entangled with Mo Rou, the valley master’s adopted daughter. Beneath Lin Qingqing’s cool exterior lies an obsession with the “Abyss of No Delusion.” Beneath Mo Rou’s prickly, unruly facade are loneliness and a steadfast heart. Their righteous and demonic allegiances set them against each other, yet identical birthmarks hint at a shocking secret: they are twin sisters separated in childhood because of the Abyss of No Delusion.
As Su Chen rises, the Qingyun Sect leadership’s conspiracy with the demon race gradually comes to light. He transforms from a “freeloader” into a hero who saves his sect, while inching closer to the central secrets of the four realms: Heaven, Earth, Mystic, and Yellow. The secrets of the Heavenly Secrets Pavilion, the dragon race’s guardianship, the ambitions of an ancient Demon God... The conflict grows from infighting within a sect to the survival of all four realms.
When the mystery of their origins is revealed, the sisters reconcile, and Su Chen fights alongside both women, using the power of the Chaos Mirror to oppose the mastermind behind everything. The satisfying rise of a hero who plays the pig to eat the tiger, the twins’ tangled origins, sect struggles where good and evil are hard to tell apart, and high-stakes adventures spanning four realms all come together in a legend about protection and bonds.
