"Ghost Sword Style!"
Ethan shouted and swung the sword in his hand.
The Blue-Cap Goblin charging in front immediately raised its spiked club, preparing to block Ethan's sword.
But in the next second, the heavy strike or weapon clash it expected never came.
The only thing the Blue-Cap Goblin felt was a cold sensation in its chest.
It looked down and saw that the tip of the human's sword had somehow emerged from its back in a strange way.
Thud!
The leading goblin dropped to its knees at once.
When the other Blue-Cap Goblin saw this, it was so startled that its eyes opened wide.
It didn't understand what had happened either, but it quickly pulled its spiked club back in front of its chest and nervously turned to look behind itself.
Then...
The next second.
Ethan's sword tip appeared beside its neck. As it turned its head, it happened to drag its own neck across the blade, leaving a long bloody cut.
By the time the Blue-Cap Goblin realized its neck felt cold, it was already too late.
[Ghost Sword Style: Experience 2021/10000]
After killing his way here, Ethan unexpectedly discovered that the experience points for Ghost Sword Style had already gone from three digits to four digits.
In other words, he had already killed around 2,000 goblins.
Looks like, today, he could use this underground goblin kingdom to level up one of the Eight Forms of God-Slaying again.
"A temple?"
Bird One looked up at the plaque hanging above the stone cave.
Two ancient characters were written on it.
The writing style resembled traditional English characters.
The words read: Temple
There were actually English characters inside the goblins' underground maze.
The moment Ethan saw those two characters, he was stunned.
He became even more amazed by the mystery of this underground world, or rather, by the mystery of its history.
"Come on, let's go inside and take a look."
The moment Ethan led the birdfolk group into the temple, countless beads around them suddenly lit up.
The beads were round, about the size of a fist, and embedded in the stone walls.
Each one emitted a fluorescent green glow.
They looked very much like the luminous pearls from ancient east.
There was a small exclamation mark above them.
Ethan stared at one for quite a while before finally realizing that it was actually.
[Imitation Night-Light Magic Pearl: A highly realistic imitation of Old World luminous pearls, created by mages who enjoy collecting Old World antiques. It normally stays lit by absorbing light elements from the air. To make it more energy-efficient, the designer made it so that the pearl automatically goes dark whenever there is no light source and no vibration or sound nearby.]
[P.S.: These are quite popular in underground antique markets. Although they have no practical use, they can be used by nobles who like Old World styles to decorate their homes.]
"Oh, so it's basically a sound-activated light."
After reading the long explanation above, Ethan came to a simple conclusion.
It was basically a magical version of a sound-activated lamp.
However, the information at the end of the prompt interested him a lot.
'Popular in antique markets?'
'That means these things are worth some money, right?'
"Collect!"
Ethan tried to collect one of the Imitation Night-Light Magic Pearls.
But after waiting for a while, the pearl remained completely still, as if it had been welded into the wall.
'Do I have to pry it out first before I can collect it?'
Ethan narrowed his eyes and quickly took out the God-Slaying Sword. He pried at the pearl embedded in the wall.
Only after it loosened did he try collecting it again.
The next second, the pearl immediately entered his backpack.
'Damn it!'
'Why was it embedded so tightly?'
Looking at the wall full of Imitation Night-Light Magic Pearls that couldn't be collected directly, Ethan felt speechless.
At that moment, Bird One seemed to notice his frustration and immediately asked, "Lord, do you want these pearls?"
"Yeah, but they have to be pried out before they can be collected. It's a bit troublesome."
Ethan sounded helpless.
Hearing this, Bird One immediately transformed into bird form.
Then she used her clawed feet to grab one of the Imitation Night-Light Magic Pearls from the wall.
With a simple swipe, her sharp bird claws dug the pearl right out.
"Holy crap! Your bird claws can actually be used for something this useful?"
Ethan was stunned.
Bird One smiled and said, "Please don't worry, Lord. Leave all the pearls in this room to us!"
"In that case, I'll leave the treasure digging to you. I'll go take a look inside."
"Yes, Lord."
After giving his instructions, Ethan headed deeper into the temple.
Because the Imitation Night-Light Magic Pearls were not very bright, Ethan hadn't noticed while standing outside the hall that the temple was actually this huge.
And in the center of the hall stood a giant stone coffin about ten meters long and five meters wide.
The surface of the stone coffin was carved with many beautiful patterns.
They looked like relief carvings depicting the legend of Medusa.
But that wasn't what surprised Ethan the most.
