This place might very well be…
Just as this thought flashed through his mind, Jiang Chengxuan heard the rapid flapping of wings.
Immediately after, a dense demonic Qi assaulted his face.
Rustle—
As a violent wind swept up, a 100-foot-tall monster appeared in front of Jiang Chengxuan. Its body was green, yellow, and brown, and was covered in thick metal armor.
Its head was triangular, and its eyes were crimson red. Its sickle-like forelimbs flickered with an incomparably sharp luster.
It was a Level 4 mantis-type demon king!
However, its consciousness seemed to no longer exist. Its body and mind were controlled by an external power.
And it was also a test for the intruders of the ruins.
If one could defeat the mantis demon king, one could continue forward.
Otherwise, they would have to go back the way they came.
In an instant, the mantis demon king's wings flapped.
