Set in a vast and mysterious cultivation world, Mo Chen is rejected by the spiritual energy of heaven and earth from birth and regarded by everyone as an outcast of the Heavenly Dao. Even basic breathing exercises provoke the wrath of thunder. Yet no one knows that a forbidden, incomplete true spirit lies dormant within him, one so fearsome that even the highest heavens dread it. When backed into a corner, Mo Chen activates a mysterious System and begins his path to a comeback. But this draws the wariness and suppression of conservative forces in the traditional cultivation sects. They obstruct Protagonist 1 from obtaining resources and sabotage the network of connections he has built.
Meanwhile, Ling Feng is also of humble origins, but harbors great ambitions. By chance, he meets Protagonist 1, and the two set off together. Although Protagonist 1's strength rises rapidly thanks to the System, his unusual constitution leaves him plagued by misunderstandings and slander in the cultivation world. He is considered an ill omen and struggles to earn anyone's trust. Resources are concentrated in the hands of traditional powers, limiting what Mo Chen and Ling Feng can obtain and making progress difficult. They are also subjected to social constraints that severely restrict their choices and actions.
As Protagonist 1 grows stronger, signs emerge that the true spirit within him is awakening. If it fully revives, the immortal realm will face an unknown disaster. Before that happens, Mo Chen must become strong enough to stand against the forces of the immortal realm and the Heavenly Dao. Along the way, they must face challenges from powerful figures in the major sects, as well as the hostility of those who resent their disruption of the traditional order. Every breakthrough comes at a great cost: Protagonist 1 must endure more Heavenly Tribulations, inflicting immense pain on his body and soul. But with their unyielding will and the System's help, Mo Chen and Ling Feng overcome every obstacle. In the end, they shatter the Heavenly Dao and break free of the cage, showing all immortals what true freedom looks like. Fresh from the oven, welcome, everyone.
