Before Lu Yuan entered this Underground World, the mayor had specifically pulled him aside and said in a low voice:
"Our probes have shown that there's a threshold for entering this Underground World. An Eighth-rank Great Grandmaster sent here from above couldn't enter.
"So, based on our initial assessment, this Underground World is extremely unusual. Its entrance can only accommodate ability users at the Seventh-rank Grandmaster level or below. We still don't know why."
Lu Yuan listened.
Then he nodded to show he understood.
At the same time, he secretly mused, This Underground World seems to have something in common with the Lost Ruins.
"Mayor, I'll head in first."
Lu Yuan waved goodbye.
With that, he leaped through the entrance and entered this newly appeared Underground World.
Inside the new Underground World.
"Here..."
After entering the Underground World, Lu Yuan first looked around.
There was nothing unusual nearby, just a vast expanse of waist-high weeds.
The tall grass in the distance rustled.
Lu Yuan immediately used his Spiritual Power to probe the surrounding area.
It turned out to be a few Shadow Cats.
After spotting Lu Yuan, they had planned to sneak over through the tall grass and deliver a fatal blow.
"You want to land a fatal blow on me? Interesting."
Lu Yuan raised an eyebrow, a hint of amusement crossing his face.
Then!
Lu Yuan merely flicked his fingers.
In an instant!
Whoosh! Whoosh! Whoosh!
Several ice spikes formed at Lu Yuan's fingertips and shot toward the Shadow Cats at incredible speed.
The Shadow Cats naturally heard the sound, but it was already too late.
Squish!
Their bright red blood stained the surrounding grass, nourishing it richly.
Lu Yuan, meanwhile, received the corresponding Evolution Points.
