Xiao Zheng continued to delve deeper along the descending passage and soon arrived in front of an iron gate.
Xiao Zheng didn't pause for a moment, walked straight up to it, and prepared to punch it to pieces.
But at that moment, he suddenly sensed a dangerous aura, and Xiao Zheng's expression changed slightly. Without thinking, he quickly retreated.
Boom!
Almost simultaneously with Xiao Zheng's retreat, countless iron arrows gleaming with a cold light tore through the air and hit the position where Xiao Zheng had just been standing.
Xiao Zheng frowned slightly.
Even if he were standing there, these iron arrows would probably not hurt him.
But this indicated that there must be many formidable mechanisms within this steel fortress.
This, indeed, was a troublesome matter.
Xiao Zheng then smiled slightly at the corners of his mouth, but it was just a few traps, so he might as well dismantle them all.
