Background: In ancient times, a disaster swept the earth. The pillars of Buzhou Mountain collapsed, the sky cracked, and there were endless heavy rains and floods. Shennong went to a crack in the sky in the northwest and built Liuyue City with the sacred tree Jumu as the foundation. Here he guided the gods to refine five-colored stones with spiritual power and handed them over to Nuwa to repair the sky. The work of repairing the sky took a long time, and the people in the human world suffered heavy casualties. There was a tribe called "Lieshan", who believed in the human emperor Shennong, who had a long life and was good at controlling spiritual energy. The people of Lieshan could not bear to see the lives of the people suffer, so they asked to live in Liuyue City to help. Shennong was touched by his sincerity and readily agreed, so he sealed a drop of divine blood into the Jumu. The life force contained in it was dissipated through the branches and leaves of the Jumu, so that the people of Lieshan could live without food and drink. The progress of repairing the sky was difficult. Emperor Fuxi then used the magic sword Zhaoming to go to the East China Sea to kill the giant turtle. The foot was used to support the four poles, temporarily stopping the collapse of the sky. The floods were stopped, and the cracks in the sky were repaired soon. However, Zhaoming was broken and damaged after the battle, and no longer looked like a magic sword. After the disaster, the turbid air in the human world overflowed, and people died of illness. Fortunately, Liuyue City was high in the sky, and the turbid air was thin, so Shennong ordered the Lieshan tribe to stay in the city temporarily until he could find a suitable place to live. A few years later in the human world: Le Wuyi, who loved the art of Yan, ran away from home to find the great Yanshi Xie Yi. On the way, he met Wen Renyu and Xia Yize who were looking for Xie Yi. Hard work pays off. After the three of them achieved their goal, they accidentally entered Taoyuan Xianju in Xie Yi's house and rescued the goddess Aruan who was sealed in the atlas. After Aruan was unsealed, she learned that Xie Yi had lost her memory a hundred years ago because of looking for the mysterious ring, so the five of them decided to set out to find the ring and find out the truth. Unexpectedly, they gradually discovered that many things were closely related to "Liuyue City", and Liuyue City also changed due to the invasion of the inner demon... The truth became clearer and clearer, but in the end it reached a point where it was out of control...
