Once Sha Huoyan and Shao Yunxi officially became soul cultivators, Zhang Fei stopped their dual-soul cultivation. He then imparted a few other techniques to them, such as the Nine Heavens Illusory Avatar Technique to speed up their cultivation and the Scarlet Furnace Body Method to strengthen their physiques, especially since they were fire-type beasts.
It was not difficult for Sha Huoyan and Shao Yunxi to learn the Nine Heavens Illusory Avatar Technique, and each of them managed to create six and seven avatars in a few minutes. However, they couldn't immediately master the Scarlet Furnace Body Method, especially since they needed the help of external flames to do so.
After they understood the method, Zhang Fei asked Sha Huoyan and Shao Yunxi to get naked, which perplexed them. After he explained to them how to train the method, they immediately took off their dresses, leaving their faces completely red.
