Wu Longzi told Shi Feiyang that he had a friend, a millennia-old Chinese Toon tree that grew on the East Great Road, which had attained spirituality and formed a Primordial Embryo, intending to reincarnate into a human body in the home of a disciple of the Lord of the Eternal Night City, Qian Kang. However, an unexpected event had occurred since the year before last.
At that time, it was the Winter Solstice, and disciples of Shenjun Zhenyue from the East Sea took advantage of the weakness during the Aurora Fire to gather herbs and tour the Outer Heaven Divine Mountain and made a visit to the Eternal Night City, where they were warmly welcomed by Qian Kang's disciples.
The Chinese Toon tree heard that the two disciples of Shenjun Zhenyue wanted to use it to create a Buried Wheel Electric Light Disc, and one of Qian Kang's disciples said that his master was planning to deal with the Black Dragon across the sea and asked for their help.
