Because up to this moment, he really didn't have any good way to improve his strength.
Methods that only raise his strength a little are useless to him right now; he has to push his strength all the way up to Heavenly Rank Perfection, otherwise once he joins the battle, it'll be a disaster for him.
When that happens, not only will he be unable to help the old Daoist and the Devouring Sky Python, he'll instead become a burden to the two of them.
So he has to raise his strength to Heavenly Rank Perfection in a short time; otherwise, just improving a bit won't be any use at all.
"What should I do?"
For a moment, Chen Feng looked somewhat anxious, because he really couldn't think of any good way in such a short time.
He took a deep breath.
Chen Feng thought of the Tianqi Holy Pearl, but the functions the Tianqi Holy Pearl currently had were only healing injuries, restoring True Qi, and boosting Martial Arts. As for increasing Chen Feng's own strength, it basically did nothing.
