Li Huayuan was a renown Core Formation elder of the Yellow Maple Valley Sect originating from the State of Yue on the Heavenly South Continent. He had a Foundation Establishment wife surnamed Zan. As an elder of the Yellow Maple Valley he had several personal disciples. However, he would not personally train them. Instead he chose to leave them to their own devices.
Li Huayuan first met Han Li while ferrying Qi Condensation disciples of Yellow Maple Valley to the Trial by Blood and Fire. The trial was an inter-sect competition between the Seven Sects of the State of Yue designed to cull the number of disciples that would be given a Foundation Establishment Pill. Li Huayuan did not take notice of Han Li who was a Qi Condensation cultivator at the time. After arriving at the trial-grounds, Li Huayuan involved himself in a friendly bet between himself and elders from the Clear Void Sect and Masked Moon Sect. The winner of the bet would be the Sect whose disciples (1) collected the greatest number of spiritual medicines, followed by (2) the quality of the spiritual medicines and finally the number of disciples alive at the end of the trial.
As the Trial by Blood and Fire ended, Li Huayuan was mortified with poor number of Yellow Maple Valley survivors. He ultimately lost the bet between sects even though Han Li and Xiang Zhili unexpectedly collected a vast number of spiritual medicines. Li Huayuan extended Han Li an opportunity to become a disciple in-name in order to confiscate half of the spiritual medicines that Han Li collected duuring the trial. Li Huayuan offered Han Li to become an official disciple if Han Li increased his cultivation level to the Foundation Establishment realm. However, Li Huayuan did not truly believe that Han Li could reach Foundation Establishment given his poor Spiritual Roots. This resulted in Li Huayuan largely forgetting Han Li existed.
Li Huayuan used the spiritual medicines stolen from Han Li to treat his Wife's life-threatening condition. Since she had been cured by the medicines, Li Huayuan had intended to reward Han Li by officially accepting Han Li as a disciple before reaching Foundation Establishment. However, since Han Li had reached Foundation Establishment without assistance, Li Huayuan was forced to let Han Li select a cultivation art. Unknown to Li Huayuan, Han Li took a rare hidden cultivation art called the Three Essence Revolutions Technique disguised as a golden page.

While the Treasure Seizing Assembly in the Yan Clan was happening, the Seven Sects of the State of Yue heard news about invasion of the Six Devil Dao Sects. After victory in an ambush battle, defensive line was set up at the border shared by the State of Yue and the States of Jiang and Che Ji. Li Huayuan served there wit hhis wife. One day, he sent Han Li to protect Qin Clan in Yuejing, because he feared the Six Devil Dao Sects might sent groups of cultivators to kill connected entities in the secular world.
After betrayal of Spirit Beast Mountain, the Six Devil Dao Sects had great victory and the Six Sects of the State of Yue and allies from two other coutries suffered great losses. The State of Yue was in great turmoil. Despite that, some cultivators of the Six Sects, including Core Formation experts, survived and were still fighting, impeding with the Devil Dao's takeover of the State of Yue.
Eventually, remains of the Six Sects of the State of Yue joined the Nine Nations Union. They contended with the local sects and established a new foothold. They also were forced to battle Moulan Tribe's Spell Soldiers. Ten years after arriving settling there, Li Huayuan was killed in one of the battles.
