Xianyi, a modern office worker, unexpectedly transmigrates, her consciousness inhabiting a kingfisher at the boundary between the immortal and mortal realms. Bearing green feathers that can harmonize the laws of the world, she is swept into a catastrophe engulfing the four immortal realms: the Eastern Realm of Growth is invaded by freezing stillness; star-ember fire in the Southern Realm of Forging injures mortals; the Mirror Hollow of the Western Realm of Illusion shatters; and the Ice Soul Tablet in the Northern Realm of Stillness falls out of balance, turning mortals into experimental subjects.
She awakens the power to transform things and takes human form to save Qing He, a girl from the Realm of Growth. From then on, she sets out to end the conflict: repairing the Living Wood Pact so the icy lands can coexist with plants, using a buffer layer to bring star-ember fire and ice-soul stone together, restoring the Mirror Hollow to protect mortals, and exposing the truth behind the experiments in the Realm of Stillness. Along the way, she gathers Lin Ya of the Realm of Growth, Yan Hu of the Realm of Forging, Jing Yue of the Realm of Illusion, and Xue Chen of the Realm of Stillness. Together, they oppose the hardliners’ schemes, draft the Covenant of Symbiotic Laws, establish a Harmony Hall to settle disputes between immortals and mortals, and cultivate symbiotic plants to create a buffer zone between the realms.
In the end, Xianyi brings the four immortal realms to peace in her role as “Harmonizer of the Laws,” and the four mediums resonate and coexist. She becomes a kingfisher and travels across the myriad worlds, witnessing immortals and mortals helping one another and realms living in harmony. From a humble beginning, she drives sweeping change and writes a heartwarming epic of equality between immortals and mortals, and of laws that protect them.
