This episode recaps main elements of the story so far, and with Yue-er wondering about her identity. We see a huge hill-top wall and fortress complex being built by the Qin with forced labour - the beginning of the Great Wall. A huge statue falls during the construction, one of the setbacks bedeviling the project, pushing the deadline back 85 days. The frustrated Yíng Zhèng, Emperor of the Qin Dynasty demands that it be completed in 30 days. Ziming and Ziyu are still in Shanghai and see a procession of 500 Immortal Child Fairies who were allegedly chosen by the Lord in the Clouds/Yun Zhong Jun, the ship's owner, board the floating city, Mirage. Meanwhile Da Tie Chui and Dao Zhi attack a Qin convoy who are disguised as travelling traders. News about the attack travels back to the Emperor's palace and Li Si alleges that there may be a spy within the empire. (thetvdb.com)
