Even with Alex's cultivation as a mighty expert of the Supreme Realm, he still shuddered slightly under the impact of that roar.
"Heh. Quite lively, aren't you."
A trace of amusement appeared at the corners of Alex's mouth as he calmly continued walking deeper into the cave.
After he had taken about a dozen steps forward, another roar burst out.
Compared with the previous one, this roar sounded even more powerful and violent. It was filled with boiling killing intent, as if issuing a clear warning to Alex not to advance any further.
However, two roars were naturally far from enough to frighten Alex.
Spiritual energy surged beneath his feet.
His figure flickered forward.
In the blink of an eye he had already crossed the remaining distance and arrived at the deepest part of the cave.
At the end of the cavern stood dozens of iron pillars arranged in perfect order.
Using the ceiling as the roof and the ground as its base, they formed a massive prison cage.
