The explorer Gu Yumo, who lives on a fantasy planet with many galaxies in the universe, was ordered to patrol the universe to find a planet suitable for the Bodo people to survive. By chance, he came to the earth and found that the earth was the ideal planet they were looking for. He met Xin Ruohan. The Elf tribe where Xin Ruohan belongs has been tasked with protecting the earth and mankind for generations. He fell in love with Xin Ruohan at first sight and wanted to take her away, and then implemented a plan to eliminate humans on the earth. As the princess of the light elves, Xin Ruohan shoulders the important responsibility of guarding the earth. The dark elves have always wanted to defeat the light tribe and rule the earth. Their queen, Gao Sifan, pretended to obey the light elves but conspired to help Gu Yumo and Dream Planet to eliminate the light elves and humans. At the same time, the human Xi Renche has special powers. He can not only predict the future, but also communicate with the elves. He also fell in love with Xin Ruohan. The queen of the dark elves fell in love with Xi Renche and was jealous of Xin Ruohan, so she tried every means to murder her. Human beings were first deceived by the Dream Planet because they took advantage of human greed and proposed many favorable conditions. Most people are confused. The people on earth are divided into two groups, which often fight. This is exactly what Debara, the leader of Dream Planet, wants to see. One of the tactics they used was to divorce. Meng Xiaochu from the Bright Elf Tribe is an adopted human girl with special powers. She has always been Xin Ruohan's subordinate and good friend, but she betrayed Xin Ruohan and the Guangming Tribe because she fell in love with the Dark Elf Zhou Zhili. He also revealed the weaknesses of the Light tribe to the Dark tribe, causing the Light tribe to suffer heavy losses.
