Xiao Yan had put in a lot of effort and used many precious items to refine Yao Lao's body. Xiao Yan possessed the 'Green Lotus Core Flame', the' Fallen Heart Flame', the 'Three Thousand Burning Flame' and Yao Lao's 'Bone Chilling Flame', which fulfilled the requirements for refining a' Heavenly Flame'. In terms of medicinal ingredients, the Blood Essence Demonic Fruit, Ten Thousand Year Old Green Spirit Vine, and Snow Bone Ginseng were the key ingredients needed to refine the peak grade-7 pill, the Bone Growing Blood Fusing Pill. Xiao Yan had successfully exchanged for the Blood Essence Demon Fruit and the Snow Bone Ginseng at the Alchemist Trade Fair. The people from the Pill Tower had sent over the Ten Thousand Year Old Green Spiritual Vine. Moreover, Xiao Yan had successfully refined this pill at the Pill Gathering. Xiao Yan had also obtained the remains of an elite Dou Zong. However, Feng zun-zhe had later taken out the remains of a Dou Zun and even obtained the Dou Sheng right arm bone from the ancient remains to raise the quality of the remains. In terms of the bloodline essence of a rank 7 Magical Beast, Xiao Yan extracted the Ancient Phoenix Essence Blood from a Magical Beast corpse that he thought was at the peak of the Dou Zong class (it was actually a Heaven Demon Phoenix. Its essence blood was at least extracted from the bloodline of a Heaven Demon Phoenix at the Dou Zun class). He used it as a material to refine his body. Under Xiao Yan's relentless efforts, Yao Lao was successfully resurrected and broke through to the Ban Sheng realm. Later on, Xiao Yan even brought Yao Lao to the Great Thousand World.

Yao Lao had taken in a total of four disciples in his life. They were his rebellious disciple Han Feng, his beloved disciple Xiao Yan, his last disciple Xiao Xiao, and his in-name disciple Fa Ma. Han Feng had been brought up by Yao Lao since he was young. Yao Lao had treated him as his own flesh and blood and taught him everything he knew. He had even found the 'Heavenly Sea of Fire' Heart Flame for him. However, Han Feng had joined forces with the Hall of Souls to plot against Yao Lao for the sake of the 'Flame Secret', resulting in Yao Lao's death. He eventually reached the peak of the Dou Huang class and his alchemist skill was at the peak of tier 6. He was killed by Xiao Yan after joining the Hall of Souls. Xiao Yan had obtained the Storage Ring that contained Yao Lao's soul. After Yao Lao had absorbed Xiao Yan's Dou Qi for three years, his soul had recovered and he had taken Xiao Yan in as a disciple. He had even imparted the 'Flame Mantra' to Xiao Yan. Under Yao Lao's guidance, Xiao Yan's strength swiftly rose. Xiao Yan also reconstructed Yao Lao's body and helped him rise to the Ban Sheng class. After Xiao Yan became a Di, he entered the Great Thousand World with Yao Lao and established the Endless Fire Region. Xiao Xiao was the daughter of Xiao Yan and Medusa. She possessed the strength of a Dou Zong when she was born and was taken in by Yao Lao as his last disciple. She had inherited Xiao Yan's talent in refining medicine. Her Spiritual Strength surpassed Xiao Yan's at the same time and she had also inherited Medusa's beauty. After Xiao Yan advanced to the Dou Di class, Xiao Xiao's cultivation soared to the sixth star of the Dou Sheng class. When Medusa advanced to the Dou Di class, Xiao Xiao's bloodline had once again advanced. Due to her body needing to sleep frequently, her strength would increase every time she woke up. Strictly speaking, Fa Ma could barely be considered Yao Lao's in-name disciple. Yao Lao had given him some pointers when he was traveling the continent in the early years. Fa Ma's talent was limited and his level of refining medicine had only reached the peak of the fifth tier. It was difficult for him to enter the sixth tier in his lifetime and his cultivation had reached the Dou Huang class.
