Seeing the Immortal Fire undergo such transformation, Chu Yi's excitement was suddenly accompanied by an idea.
"Elder Xu, do you think my Heavenly Thunder might have the same function?"
Elder Xu hadn't thought of this. He stared at Chu Yi for several minutes and said with surprise:
"Try it, quickly try it."
Chu Yi eagerly summoned his Heavenly Thunder, letting it hover above his left palm.
The appearance of the Heavenly Thunder was much more sensational than that of the True Fire earlier.
Elder Xu and Chu Yi immediately heard a series of sharp crackling sounds.
Just like before, Chu Yi began to silently recite various colors.
Under the watchful eyes of Elder Xu and Chu Yi, the Heavenly Thunder turned red, then green, then blue...
The two of them cried out in excitement.
"Not bad, not bad, it actually worked,"
Elder Xu Fu and Chu Yi both showed expressions of astonishment.
