The green-robed cultivator said that the Qi-fusion technique practiced by Yusuf Zuck was indeed the Qi-fusion Dharma Gate of the Joyful Sect, but since Yusuf Zuck had always cultivated this particular technique, it would be difficult for him to change it in a short amount of time.
Furthermore, he did not believe the way of Qi-fusion was inferior; this Qi-fusion technique was clearly a superior Dharma Gate that emphasized the fundamental principle of Yin and Yang and offered a reliable interpretation of the universe and all things within it.
Therefore, he did not plan to abandon the way of Qi-fusion. Of course, he also wanted to practice the Devouring Technique, as it could more quickly and conveniently extract and absorb the energy of rare and wondrous treasures, clearly more beneficial than detrimental.
In the Cultivation World, it seemed no one else could directly extract and absorb the energy from such rare treasures.
