The Brainless Human Wave Attack

"Oh? So this is how it looks like beneath the Dead Spirit Swamp?" Wang Yu saw what was in front of his eyes and was in disbelief.

After jumping into the Dead Spirit Swamp, Wang Yu was not swallowed. Instead, he submerged below the swamp. However, the scene below the Dead Spirit Swamp was totally different from what was above, and was different from usual swamps.

When Wang Yu was in Twilight City, he had submerged beneath swamps and it was pitch black in them. However, it was an ocean blue under the Dead Spirit Swamp. Wang Yu's surroundings had various ocean creatures and was more beautiful than any other underwater world.

Right below Wang Yu was a huge invisible shield and within the shield was something like a city.

Just then, Wang Yu took out the Atlanta Key which was emitting blue rays of light. Soon after, Wang Yu received a system notification: "You have discovered a hidden map of the Dead Spirit City, the 'Ocean of Death'. +50000 experience points."
