Ling Hu was the Grand Elder of the Yellow Maple Valley.
He was an old man with fully white hair and a yellow, withered expression. He wore embroidered clothes.
War against the 6 Devil Dao Sects
When Six Devil Dao Sects launched suprise attack with help of traitorous Spirit Beast Mountain, main forces of Seven Sects of the State of Yue had a majro defeat and huge casualties. Afterwards, Ling Hu informed survivors in the sect about the plan to evacuate from the State of Yue, rise in power in a foreign land and return to fight back for their rightful place one day.
Once last defensive lines of main forces were defeated, Devil Dao sects sent groups of cultivators to attack headquarters of the sects. Ling Hu executed his evacuation plan. He sent a group of disciples, including Han Li, in a rush to evacuate, but secretly divulge this information to the spies of the Devil Dao to draw attention. Then he used another group of ignorant disciples to confront the Devil Dao with the great formation. All of that allowed for smooth escape of their talented elite disciples, while leaving others as ignorant sacrifices.
Old Ghost Ling Hu was present in the Soaring Heavens City, when Moulan tribes launched an invasion. He participated with other Nascent Soul cultivators in a meeting about the war. They were briefed by Enlightened Leaf Sect Master Wu Peng and the Flowing Mind Sect's Lady Qi. Afterwards, Ling Hu met with Han Li, who suprisingly reached Nascent Soul stage. As his lifespan was coming to the end, he tried to convince his former junior to join the Yellow Maple Valley and be sole ruler. Despite even offering his legacy, Han Li refused. They only came to an agreement, when Han Li accepted 3 treasures in exchange for 3 requests for help from Yellow Maple Valley.
As many cultivators were going into Devilfall Valley using the Ghost Spirit Sect's method, Ling Hu went there in a company of the Grand Elder of Masked Moon Sect and a fellow cultivator. After they encountered Marquis Nanlong possessed by an Elder Devil Bloodflame, their fellow cultivator's Nascent Soul was devoured. Ling Hu and the Grand Elder of Masked Moon Sect were running away in fright. They frantically defended themselves, until meeting Han Li. They all fought the Elder Devil. Meanwhile, it transformed into a being with 2 heads and 4 arms. Suddenly, they heard astonishing roar. Then the two-headed Bloodflame abandoned them flying towards the place, where the roar had originated. In that direction, they saw Wei Wuya fighting someone. Han Li noticed Daoist Heavencrystal and Elder Cheng Tiankun and moved to the place of battle. Despite feeling hopeless, they followed him. When they all joined Wei Wuya, 2 Bloodflame's original soul and his soul fragment confronted themselves. The original Elder Devil and its soul fragment were at odds, but they turned to devour Nascent Soul cultivators first. Ling Hu, the Grand Elder of Masked Moon Sect and Wei Wuya faced the soul fragment, while Daoist Heavencrystal, Elder Cheng, his friend and Han Li battled the original Bloodflame. After the original Devil was pulled into a spatial tear with Han Li, the other Bloodflame was heavily injured by the rest. The Grand Elder of Masked Moon Sect had her body and Nascent Soul turned into ash though. Ling Hu managed to survive only with his Nascent Soul.
Some time later, Ling Hu passed away.
