Teal Fire King was not irritated to be interrupted by Su Mo twice. He said, "To pass the Earth Gate, you have to kill!"
"Kill?"
Su Mo frowned upon hearing this. He had already killed countless malicious ghosts, and did not think that killing more of them could get him out of here.
"Correct! In the Hell Plane of the Earth Gate, you can only get out after you have killed 999,999 malicious ghosts!"
"Is it really as simple as that?" Su Mo could not believe it. He had already killed at least 100,000 ghosts, so it would not take long to kill 999,999 of them.
"Simple?"
Teal Fire King snorted and said, "Even if you have incredible cross-level combat strength, it won't be that easy!"
He did not know about Su Mo's strength, so he mocked him.
Although the malicious ghosts generated by the formation could not cast spells and they could not match same-leveled martial artists, their strength was in numbers.
