18-Year-old Liang Zichen dropped out of school heartbroken after his lover Shen Yao died in a car accident when he was 17, and spent his days numbly in a convenience store. Shen Yao's last words, "We will meet again", became his only obsession. On the night of Shen Yao's 20th birthday, he returned to his old residence, traveled to the Qi Dynasty in the mysterious sea of manzhu, sand and flowers, and became the 22-year-old King of Liang in Nanhu. A jade birthmark appeared on his left shoulder.
He was shocked to find that Shen Yao traveled through time three years earlier than him and became the 21-year-old Jinghu Yue Oiran, but had completely forgotten his past. With the help of the hermit counselor Zhou Quan, Liang Zichen used modern wisdom to implement the New Deal, which won the emperor's appreciation, and at the same time approached Shen Yao again as the "Prince of Liang". The two broken pieces of "Tongxin Jade" gradually came together, finally awakening Shen Yao's memory, and the lovers across time and space embraced each other again.
However, this love, which is not allowed in the world, was criticized by political opponents such as King Kang. After the Kaiming Emperor died of illness, the new emperor ascended the throne and joined forces with King Kang to liquidate: Liang Zichen was deposed and beheaded, Jinghuyue was burned, and Shen Yao's adoptive mother Shen Qingping died in the fire to save him. Zhou Quan risked his life to rescue Liang Zichen, and the two fled to the Moon River, where they were surrounded by pursuers. Holding the composite jade pendant tightly, they jumped into the roaring river with smiles, practicing "love is the eternal direction" with their lives.
Zhou Quan buried the two together and engraved an oath on the tombstone. In the modern hospital, Liang Zichen and Shen Yao, who had been in coma for three months, woke up at the same time. The jade birthmark on their left shoulder was slightly burned. They looked at each other and smiled, recalling their past. Returning to school and convenience stores, the weather vane is gently turning in the wind - true love spans the time and space of life and death, and finally ushered in a perfect stay together in this life.
