At some point, Fu Cheng acquired the refinement formula for ancient Nascent Cultivating Pill. Materials were very hard to find. After 70 years, stumbled upon an Umbra Yin Horse. Because of grievances in the past, he had become hostile with most Nascent Soul cultivators in his sect. Apart from Chang Zhifang, the rest were looking forward to the day he died. He didn't want to work on the pill with them, because he feared their betrayal.
First Meeting Edit
While Fu Cheng was at the Hidden Fortune Pavilion, he met there Han Li. Old Man Fu traded his Thunderspirit Crystal for Han Li's Scarlet Essence Mushroom and told him about a secret underground trade fair conducted by the Devil Dao factions. Later, Old Man Fu took Han Li to the underground auction and helped avoid Yin Sifting Sect Elders looking for him. He hoped for Han Li's help in private matter. When Han Li wanted to leave the auction, they scheduled to meet in 4 years in Nanjiang Province's Chaoyun Prefecture.
Nascent Cultivating Pill Edit
When the time came, Fu Cheng travelled to the Twin Scorpion Mountain in the Nanjiang Province with Elder Chang Zhifang. He was happy seeing there Han Li, Bai Yaoyi and Sacred Poison Sect's cultivator Yuan. All of them were there after owning a favor. Then he explained them this matter was about ancient Nascent Cultivating Pill and finding materials for it, like the flesh of an Umbra Yin Horse. The problem was its nest was in dangerous Yin Yang Cave, which made others apprehensive. Old Man Fu also said they would be entering in 6 months and asked everyone to sign an Underworld River Page swearing an oath to not tell anyone about this.
Half a year later, everyone met again and they set off to the Myriad Poison Valley. Cultivator Yuan's poison warding treasure help them easily traverse it. Inside the cave, Fu Cheng was using his sect's Dark Violet Pearl to protect from the black Yin winds. and they battled Yin ghosts. After a month, they finaly found traces of the creature deeper in the cave. They also encoutered Corpse Wolf that was with the horse. Everyone attacked the Corpse Wolf. As the wolf started to run away, they followed. cultivator Yuan's was killed by the Silver-winged Nightfiend and Fu Cheng and Bai Yaoyi were tapped in the cocoons. Chang Zhifang and Han Li clashed with trapped in the spell formation Nightfiend, who was said to be superior to even late Nascent Soul cultivators. As Chang Zhifang tried to save others, the Nightfiend tore her body apart with claws and put her Nascent Soul into a cocoon. When Han Li was attacking the Nightfiend with Triflame Fan, the formation was activated suddenly and teleported everyone present.
Kunwu Mountain Edit
Nightfiend, free from trapping formation, immediately run away after eating Chang Zhifang's Nascent Soul. Han Li rescued Fu Cheng and Bai Yaoyi and gave the old man captured Umbra Yin Horse. They were teleported near the giant mountain. Old Man Fu was saddened by the death of his Junior Martial Sister Chang. After finishing refining the Nascent Cultivating Pill, Bai Yaoyi got one, Fu Cheng took one pill too and the other 3 he gave to Han Li. Since Han Li was more powerful than them and the old man didn't want him to suddenly turn hostile. Next, they travelled up the mountain looking for an exit. They found out it was legendary Kunwu Mountain. Soon after, they were trapped by illusion formation, but Han Li broke the restrictions after some time. Then they met the Unbroken Cinque Devils of the Grand Elder of the Yin Sifting Sect, which terrified them. Fu Cheng tried to reason with him, as they both were from Devil Dao alliance, but old Devil Qian was set on to reclaim the lost Ghost Sifting Banner. Bai Yaoyi sticked to Han Li, who was a powerful ally to her and would be useful in this place. Then they were joined by Sacred Poison Sect's Grand Elder Hua Tianqi, Zheng Wei and other vagrant cultivators. Hua Tianqi proposed to suspend all conflicts and go together up the mountain to look for treasures, since the exit was blocked.
As they travelled, they were forced to destroy formations left behind by other group. As they arrived near the top of the mountain, they found many staircases. Almost everyone split up. After Han Li went alone too, Fu Cheng stayed with Bai Yaoyi. Bai Yaoyi and Old Man Fu acquired quite a few gains in one of pavilions. After a change occurred in the sky above the Devil Suppressing Pagoda, they headed there. When running into many other powerful cultivators, they were attacked before they could leave. Bai Yaoyi managed to flee heavily injured. Old Man Fu was killed by Master Scatterwind.
