Lei Chen

Lei Chen is the Crown Prince of Fire Country a.k.a Yan Country in some translations.

Originally, Jun Wu Xie and the gang believe that Lei Chen has a piece of the skin map after running into a group of explorers at the top of Heaven End's Cliff. The explorers had a paper version of a skin map and were sent by Lei Chen. After determining that Lei Chen did not have the real map, but his father (the Emperor) did, Jun Wu Xie forms an alliance with Lei Chen.

Under hypnosis, Lei Chen reveals that he is currently being schemed against by his imperial father and brother to force him to give up the position of crown prince. Lei Chen also reveals that he is not the Emperor's and Empress's son; he is the child of a maid who gave birth at the same time as the Empress. The Empress's child died, so she replaced him with Lei Chen.

Jun Wu Xie assists Lei Chen in ending the rumor that the Crown Prince was fixing the matches against Jun Wu Xie by having Hua Yao impersonate Zhao Xun (her opponent). Jun Wu Xie shows off her Green Spirit showing how she didn't need to fix the match to win, while Hua Yao spreads the rumor someone was framing the Crown Prince.

After Qu Ling Yue is harmed by Imperial Physician Li to frame Jun Wu Xie as violating the rules of the Spirit Battle Tournament and bring the wrath of Thousand Beast City down on her head, Lei Chen brings Jun Wu Xie (as herself not as Jun Xie) to treat Qu Ling Yue. Jun Wu Xie gives him the credit for saving her and earns him the respect of Thousand Beast City.

After Wen Yu reveals that the ring Jun Wu Xie picked up in the Dark Emperor's tomb is the "Ring of Imperial Fire," Lei Chen decides to push the position of Emperor onto Jun Wu Xie as the Late Emperor's Imperial Edict stated that whomever returned to Fire (Yan) Country with the "Ring of Imperial Fire" is the rightful heir.

He develops feeling for Qu Ling Yue, the Fire Country Empress.

Chapter 3116 Qu Ling Yue thanks Jun Wu Xie and tell her that she wants to move forward. She then asks Lei Chen if he's bothered by all the things that happened to her and thing she's done. Lei Chen replies that he doesn't.
