Xing Zhe shivered hearing Yang Xiao's words and hurried a few steps forward, closely following behind Yang Xiao.
"Yang Xiao, do you think there might be a higher level Mountain Cannon Demon Beast ahead?"
"It's not a guess, there certainly is, and the smaller Mountain Cannon Demon Beast I just killed is very likely the child of that higher evolution level demon beast."
"Damn, if that demon beast knows we killed its child, won't it come after us for revenge?"
"What do you think?"
Yang Xiao didn't stop for a moment and quickened his pace to run forward.
However, in this Underground River Tunnel, they couldn't run too fast.
The two ran back to the spot where they had previously slept and rested.
Xing Zhe was about to jump onto the shore to rest, but he saw Yang Xiao dive directly into an underground river water cave, submerging instantly.
Xing Zhe didn't dare to linger either, followed Yang Xiao into the water cave, and continued forward.
