When Ye Chenfeng wanted to continue, he only felt a stabbing pain throughout his meridians, making it impossible to perform the Thousand Thunder Flash.
As he frowned tightly, the old man Wu Fengxian said, "Young one, you needn't be overly concerned. This Thousand Thunder Flash is a Four-Star Secret Method. Do you think a Four-Star Secret Method can be used without any restrictions?"
"Using the Thousand Thunder Flash places a very heavy load on your body, so naturally, there is a time limit. I suppose after resting for a while, you will be able to use the Thousand Thunder Flash again."
Ye Chenfeng nodded silently. To be able to continuously use the Thousand Thunder Flash for thirty seconds was indeed quite impressive, after all, his Martial Arts of Profound Meaning, Rage, could only last for ten seconds!
