The Immortal Flame Emperor Bell was a cultivation treasure, and he needed to refine it before he could use it. Before it was refined, it couldn't be used, and since taking out an Innate Treasure typically wasn't a subtle affair, he didn't bother taking it out inside the White Jade Skyship—in case the Leaving Fire Sect Ancestor noticed it and grew greedy, which would only complicate matters.
After all, the Leaving Fire Sect Ancestor was an Immortal Venerable Peak powerhouse, and Lu Yi felt it was still necessary to show some respect.
He planned to refine it once he returned to Ling Luo Peak.
The 'Nine Heavens Tribulation Fire' of the Origin Immortal Skill was something he could contemplate, but he still planned to use the reward he got from his Fire Origin Understanding first.
Just like Laws, the mastery of Origin Power also varied in degrees.
