The soul of poetry for thousands of years travels through the modern world. Yuan Zhen and Wei Cong accidentally woke up in contemporary Dazhou, Sichuan on the "Yuanjiu Climbing Day" and found that the oath of "once the sea" is facing a new test. The lantern-shadowed beef shop on a windy and snowy night in Tongzhou, the monument of Bai Juyi's prophetic poems on Phoenix Mountain, the echoes of Liu Yuxi's poems written on bamboo branches in the Batai Mountains—the landscapes and gourmet restaurants in Dazhou are full of hidden codes of past lives and crises of this life.
When the steamed fish banquet on the stone ladder turned into an official gambling game, and there was a murderous intention hidden in the eight pieces of Sanhuishui; when the "Poetry of Compassion for Farmers" turned into a report letter, and the "Lianchang Palace Ci" insinuated political achievements; when the secret recipe of Dengying Beef was involved in the business war, and the sound of shotguns sounded in the Bashan Grand Canyon - seven poets of the Tang Dynasty reunited with different identities, and in the secret battle of tongues and mountains and rivers, they used their poetry for thousands of years to protect the city's culture and people's livelihood.
Wei Cong embroidered poverty-stricken clothes again on the sickbed, Yuan Zhen went to Bashan three times to find old oaths; Bai Juyi showed up at the planning bureau to turn the tide, and Han Yu spoke out to advocate for cultural heritage. From the suspicion of excavation of the Luojiaba ruins to the grand blueprint of "Poetic Road to Dazhou"; from the official secrets in the seven-star pepper stewed vegetables to the eternal poetry monument by the Lotus Lake - they use poetry as their sword and true love as their shield. In the puzzle of ancient and modern times, they unveil a journey of guardianship that spans thousands of years.
"The heart of poetry mirrors the moon, where does the soul go?" When the sea turns into the rain of Dazhou, Wushan has become the clouds of Bashan. The seven souls of poetry make a new decision in the undercurrent of the official world and the storm on the tip of the tongue: Should they return to the long river of history, or stay in this dream home that allows them to regain their original aspirations and renew their relationship?
