Qin's Moon: The Legend of Qin

Ge Nie and Jing Tianming are attacked in the desert. After fending the enemy troops off, Ge Nie is injured and is found, along with Tianming, by the Royal Tribe of Chu. They are then attacked by an assassin sent by Wei Zhuang.

The assassin is defeated by Ge Nie and the group takes off for an unknown area. Wei Zhuang dispatches Grey Wolf to deal with them.

After fending off the Grey Wolf assassin, Ge Nie's injuries reopen. At that time, Gao Yue (Yue-er) appears and leads them into a Mohists Manor, where Duanmu Rong, a doctor, is. Although reluctant to treat his wounds at first, she later changes her mind. Master Ban reappears in this episode, to prevent enforce the orders given by Duanmu Rong. Jing Tianming breaks Duanmu Rong's sign of the three who will not be treated.

Ge Nie has finally recovered and converses with Master Ban, regarding the insanity curse on Jing Tianming. The Qin's spies infiltrate the Mohist Manor, prompting Ge Nie, Tianming, Duanmu Rong and Yue-er to leave immediately. On the way, they are attacked by a giant bird at a cliff.

After they are stranded on the cliff, it is then revealed that Gao Yue is actually the princess of the Yan kingdom. Her father was supposedly killed by Ge Nie, and she plans to take revenge. Wei Zhuang's female assistant Chilian (Crimson Lotus) appears and controls Yue-er, coercing her to make Duanmu Rong kill Ge Nie. Master Ban then arrives on a mechanical giant bird, and successfully retrieves everyone except Yue-er who topples over into the cliff.

Yue-er is successfully rescued, and the truth regarding her father's death is revealed. Her father was really assassinated by Wei Zhuang and his female assistant, Crimson Lotus, changed the memory of Yue-er so she thought that Ge Nie was really the one who killed her father. In addition, a plot involving the assassination of the Qin Emperor is revealed to have taken place years ago, one that ultimately failed.

Jing Tianming learns about the Hundreds of Schools of Thought and the 300 year conflict between the Mohists and the Gonshu Clan both famous for their mechanisms. A giant bird attacks their mechanical bird and Master Ban receives a poisonous wound. They are then attacked by flocks of birds controlled by White Phoenix/Baifeng of the Quicksand clan. Yue-er pilots the mechanical bird for Master Ban and they manage to escape into The Mohist mountain city. Tianming learn all about the legends of the place and the Mohist philosophies. Back in Xianyang Palace Prime Minister Li Si tell the Emperor about the difficulty of attacking the Mohist stronghold.

Jing Tianming learns more about the Mohists and the construction of the Mechanical City. Dao Zhi arrives. Emperor talks about his dream to unite the six nations under the Qin which leaves no place for the separatist Mechanical City to exist. Because normal troops could not successfully attack the Mechanical City, he plans for the Quicksand and Gongshu Clans to infiltrate and defeat Mohists. Meanwhile Master Ban explains the many traps and defense mechanisms built for defense. Ge Nie realises that Tianming has potential, but is still young and naive and will need a lot of guidance to achieve his potential. They meet teacher Xu whose mother forged Ge Nie’s sword, Rainbow Abyss. Meanwhile Wei Zhuang decides to send in Hidden Bat and Lin-er to infiltrate the Mechanical City.

Ge Nie learns that there is a sword in the Mechanical City held by Xiaogao called Cold Water which is the opposite of his sword, Rainbow Abyss. Tianming witnesses a contest of strength between Da Tiechui and Xiang Shaoyu to lift a huge bronze vessel weighing 1,250kg carried in by 12 of the strongest men. Both lift the vessel, but because of Xiang Shaoyu’s age, he is the winner. Tianming sneakily throws stone at Shaoyu from the audience and Da Tiechui tries to punish him, but Tianming manages to evade the huge man’s blows. Xuenu intervenes to stop the fight, but warns Tianming if the acts badly in the future, the punishment will be severe. Duanmu Rong sees hope for the future in the three orphans - Jing Tianming, Xiang Shaoyu and Yue-er.

Hidden Bat enters the Mohist Mechanical City. Moon Goddess demonstrates the power of Yin Yang to the Emperor and talks about the child threatening the empire, Jing Tianming, and predicts that he will kill Ge Nie. At the Mechanical City Master Ban suspects that Qin forces will not try a frontal attack, but will use stealth to breach the defenses. In an experiment, Wei Zhuang pits a Mohist machine against a Gonshu Clan snake to see which will win – the Gonshu snake. While on patrol at the perimeter of the Mechanical City Da Tiechui and troops encounter Hidden Bat.
