The Twin-Star Mentor in the Storage Ring

When the soul of a young man from Earth merges with Han Li's memories from A Record of a Mortal's Journey to Immortality, he unexpectedly transmigrates into the world of Battle Through the Heavens, becoming the second mysterious soul inside Xiao Yan's ring. From then on, Yao Lao is no longer the only “old grandpa” in the ring. Cautious Han Li, who carries secret spiritual-sense techniques from the cultivation world, and Yao Chen, an unrestrained master of Dou Qi and alchemy, begin a cultivation plan for Xiao Yan with two very different styles.

Faced with the shadow of the Hall of Souls and the Three-Year Agreement, Xiao Yan grows rapidly under the guidance of two masters with completely different teachings. Yao Lao teaches him the Flame Mantra, while Han Li tempers his spiritual sense and character. One teaches him to become a revered alchemist; the other teaches him how to survive. When the Purifying Lotus Demon Flame appears and Hun Tiandi's ambitions are laid bare, the two mentors will join forces to reveal an ultimate battle beyond all imagination.

This is the legend of the Flame Emperor, written by transmigrator Han Li and Yao Lao together, as well as an interdimensional epic about a mortal becoming an emperor under the tutelage of two masters.
