Chu Feng was pleasantly surprised.
He had been a C-rank goalkeeper for too long.
Even if his true strength was comparable to an S-rank expert, rank was still his weakness.
Previously, he had no choice because he had to undergo the first of the top-notch nine tests. He could only constantly compress his spiritual energy and suppress himself to C-rank.
Later on, although the first test had been completed, Chu Feng was no longer in a hurry to break through.
The reason was simple.
To the current Chu Feng, if it was just a breakthrough at the mortal stage, such as advancing from the C-rank to the B-rank, A-rank, or even the Spirit Transformation realm, there would not be a significant increase in his strength.
Because his strength far exceeded his rank!
Unless he transcended the Mortal Lightning Tribulation and broke through to the A+ rank, there would be a huge transformation.
However, Chu Feng did not dare!
