193 History of Yan Clan

Great Grandpa Rui had provided Han Cai with two cultivation techniques, one for Flame Qi and another for freezing Qi, but they both were lower-grade techniques than what Han Cai had, so Han Cai only pretended that he was cultivating those techniques while he cultivated the Celestial Ascension Cultivation Technique and converted it into frigid Qi and flame Qi with the Frigid World Cultivation Technique and another cultivation technique called Crimson Spirit Technique. He did not have to put extra effort into these two cultivation techniques as he was already cultivating far superior Qi and cultivation technique. 

Yan Rui did not have frigid Qi-related fighting skill techniques, but he gave Han Cai fighting skill techniques for Flame Qi. But Han Cai was not lacking in fighting techniques for frigid Qi either because he had the portable grandpa, who was a prisoner of Yongnian, to help him there.
