The next morning, Lei Cheng pushed open the great door of the Secret Chamber.
Upon looking up, he found himself staring into a pair of bloodshot eyes in the pitch-black chamber.
Even with his usually calm disposition, Lei Cheng's heart skipped a beat.
Only when he recognized the figure in front of him did Lei Cheng let out a sigh of relief, "Mr. Gongsun? What's the matter with you...?"
"That drum is not right!" Chen Mu said, rubbing his somewhat dry eyes, his expression grave.
After going back last night, the more he thought about it, the more he felt that something was off.
He returned to the Secret Chamber overnight and began to tap on the brand-new Kui Niu Drum inch by inch to probe it.
After spending the entire night, he finally detected an abnormal sound using the Truthful Listening Technique.
"Compared to the original Kui Niu Drum, there's something extra inside this one," he said, regarding Lei Cheng with gravity.
