After that, people continued to walk past the waterfall one after another.
During this time, the Beast Tribe's minor leader produced a stone in his hand.
More accurately, it looked more like a token.
And whenever someone passed through, the token in the minor leader's hand would display a number — the cultivation level of whoever had walked through the waterfall.
At first, the cultivation levels of those people were exactly what they appeared to be.
However, when an old man passed through the waterfall, the minor leader's expression suddenly changed dramatically.
"Hmph, hiding your cultivation — trying to infiltrate our tribe, are you? Men, seize him!"
The Beast Tribe's minor leader pointed at the old man who had just passed through the waterfall and roared.
"Wahahaha! I was wondering how such a waterfall could appear here. So in the end, this waterfall is actually an array that exposes one's cultivation level."
"But so what if you've discovered me? With your pathetic strength, you think you can capture me?"
"A bunch of beasts — not only will I kill you all, I'll take your treasures!"
After his cultivation was exposed, the old man's demeanor immediately changed, and a mocking smile crept across his face.
In that instant, his aura underwent a tremendous transformation — from a Ninth-stage Martial Ancestor to a True Immortal.
This strength surpassed every member of the Beast Tribe present, since even their minor leader was only a Third-stage True Immortal.
*Pu—* But just as the old man was gloating and about to strike down the Beast Tribe members, a blade of light suddenly shot out from deep within the cave and pierced straight through him.
The next moment, the old man collapsed to the ground with a look of utter disbelief, his life extinguished.
"There's a powerful expert inside that cave — a Ninth-stage True Immortal."
Chu Feng's eyes narrowed. Before that Ninth-stage True Immortal struck down the old man, even Chu Feng hadn't sensed anyone else inside the cave.
Moreover, after he struck, his aura vanished immediately.
But the moment he attacked, Chu Feng had clearly caught his aura.
Indeed, a Ninth-stage True Immortal was hiding deep within the cave, and he must have possessed an extraordinarily powerful concealment method — otherwise, even Chu Feng wouldn't have been unable to detect him. Only when he struck could Chu Feng sense his existence.
"Hmph, did you really think we were all fools? A mere True Immortal trying to sneak into our tribe."
Looking at the fallen old man, the minor leader let out a mocking laugh, then bellowed: "Continue."
Then, urged on by the Beast Tribe members, the others continued to walk past the waterfall one by one, and before long, it was Chu Feng's turn.
