According to the historic records, nine thousand years ago, a calamity befell the vast lands, killing many strong cultivators and resulting in the destruction of martial arts and alchemy legacies. After several hundred years of chaos, the vast lands were finally reconstructed, forming the modern-day layout.
Ling Han saw his own name in the records. In his previous life, he was also known as the Grandmaster of alchemy, innovating the Three Fire Guide technique, which sadly seemed to have been lost.
However, his two disciple's names that learned alchemy from him weren't in the historic records.
Not only them, but also Jiang Yue Feng, and Cheng Rui Jing, the two martial arts disciples were not mentioned, as if they never appeared in this world. Moreover, Ling Han didn't see Sword Emperor and Heavenly Phoenix Divine Maiden's biographies.
