The end of the spiritual wilderness has arrived, alien beasts are running rampant, and the living space of human beings has been drastically compressed. The protagonist Jiang Lichuan was originally the most talented spiritual master disciple of the Lingxu Sect. He was expelled because he opposed the master's use of spirit beasts to refine souls into medicine, and he lived in a deserted city. Relying on his natural empathy and ability to observe spiritual beasts, he created the "heart contract" model (equal sharing of perception and complementary strength with the spiritual beasts), and successively contracted with spiritual beasts such as green wolves, fire foxes, and ice silkworms to struggle to survive in the apocalypse. In the process, he met Yue Qingluan (Poison Master/Gu Girl), the leader of the Miaojiang Qingluan Tribe. The two went from the antagonism between "humans and tribes" to the cooperation of "jointly fighting against the Soul Refining Cult". They formed a "Spirit Alliance" to collect ancient spiritual contracts and uncover the truth about the spiritual wasteland - the ancient beast "Chaos" awakened due to the soul refining technique and needed to gather the power of all the spiritual contracts to seal it. The protagonist leads the alliance of humans and spiritual beasts, and goes through several life-and-death team battles, finally defeating Chaos and ending the apocalypse.
