Klein looked around and suddenly, a new notification appeared in front of him.

[This is a mysterious place. It seems to have happened before. There's some scattered information.]

Information?

Klein was taken aback.

Could it be about Raksha?

With this in mind, Klein picked up the shovel beside him and barged in.

After entering, he saw darkness.

A rotten smell assaulted his nostrils.

Klein hurriedly activated the wind element to dispel the smell of the catacomb. Then, with a tap of his hand, a flame appeared at the tip of his finger.

The flame rose, and everything in the catacomb appeared in front of Klein.

There were scattered wooden frames everywhere, and there was some paper mixed in between the frames.

Under the paper, there seemed to be the bones of some kind of creature.

Klein slowly reached out his hand, but the moment he touched it, the paper instantly shattered.

"Has it weathered?"

"It looks like this place has been sealed for too long!"

Klein muttered to himself.

Therefore, he had no choice but to be even more careful. In the end, he found only a few pieces of well-preserved content in the room full of paper.

After Klein finished organizing them, he began reading them under the flames.

"This is a huge cataclysm. All of them are dead. No, there seems to be one who survived."

"No, no, no. How could this be? Why are you treating us like this?"

"On the ninety-ninth day, I still haven't found a way out. I'm almost unable to hold on any longer!"

...

This seemed to be a diary.

Klein looked at the distorted text on it.

If it wasn't for the system's help, he wouldn't have been able to understand such strange words.

But they were too incomplete. Most of them could only be seen in bits and pieces.

From the information inside, there seemed to be a huge change.

There was a person who survived.

Perhaps it wasn't a person.

Most importantly, he seemed to have lived here for a long time.

And he was alone.

He still couldn't find a way out.

Klein couldn't understand the meaning of the content at all. He could only look at the last page.

The last page was simple. There were only a few pictures.

There was a dried-up hand in the picture. It seemed to be fiddling with something.

Most of the color on it had faded.

However, the thing in his hand, Klein seemed to have been seen somewhere before!

Klein seemed to have thought of something. He took out the key and compared it carefully. Sure enough, these pictures were about the use of the key!

Klein quickly memorized it and searched the room again. There was nothing on the ground except for some wooden frames and bones.

The bones were also very strange. They looked very human.

They had four limbs and a head, but they were very short.

Could they be dwarves?

Klein couldn't make a guess.

He knew too little about the catacombs world.

There was no way he could guess what they were.

He could only shake his head and leave the room. He went to the door and opened it with the gesture he could get.

It seemed like no one had opened the door for a long time.

Klein pushed open the heavy stone door with all his strength.

The sound of the rocks rubbing against each other was very ear-piercing in this empty space.

Accompanied by the strange atmosphere, Klein couldn't help but feel his hair stand on end.

Klein stepped in, and there was endless darkness inside.

He couldn't even see his own fingers.

Standing at the door, he could only feel the endless emptiness inside.

It seemed to be very large inside.

'Is this where Raksha stays?'

'It's so dark. No wonder the system notified me that Raksha is afraid of the light.'

With this in mind, Klein didn't hold back. He rubbed his hands together, and endless flames spread out from his palms, instantly lighting up the empty space.

Pa!

Suddenly, a sound was heard.

It sounded like a rock had fallen to the ground.

Klein looked in the direction of the sound and saw a hill that was as tall as a person.

A rock the size of a washbasin was smashing down at him from the hill.

It wasn't fast, so Klein easily dodged it.

The falling rock made a loud bang on the door, which was particularly jarring in this empty space.

Klein retracted his gaze and looked around. There were small mountains everywhere.

However, there were no plants on these mountains.

It was as though this was a land of peril.

Klein didn't mind and continued walking forward.

If he wasn't wrong, Raksha should be hiding here!

However, when he took a step forward, the hair on his back suddenly stood up.

It was as though a great crisis had struck him.

Klein was alarmed as he hurriedly brandished the Golden Firestorm Saber in his hand.

With a crisp sound of metal clashing, a flame inexplicably flashed in the air before it disappeared.

"What is this thing?"

Klein did indeed sense a power.

It was extremely huge.

He hurriedly blocked it, but it actually shook his arm until it went numb.

'Could it be Raksha?'

Klein couldn't help but think.

'That's not right. The system's notification said that Raksha is extremely afraid of light.'

With so much light emanating from the flames, he would definitely die without a complete corpse, much less make a move.

'What on earth is that?'

Klein raised the flames and looked around.

His surroundings were still empty, as though nothing had happened.

It was as though Klein had hit a rock.

Just as he was about to take another step, he suddenly felt a gust of wind at his ankle.

"Oh, that's not right!"

Klein immediately jumped up.

The rock that Klein was standing on was instantly shattered.

Countless pieces of rubble flew in all directions as though they had exploded.

Klein narrowed his eyes and said, "There really is something!"

"As expected of the lair of Raksha. It looks like if we want to take down Raksha, we have to get rid of these annoying monsters!"

Klein shook his head and then increased the eruption of flames.

At this moment, Klein's hand was like a volcano. Countless fist-sized fireballs flew out of his hand and reached their limits. They exploded in the sky and shot out in all directions.

Instantly, countless flames spread around Klein like a flaming mountain.

The searing heat wave was so intense that even the rocks on the ground couldn't withstand it. They emitted a bouncing sound as though they would explode at any moment.

After doing all of this, Klein wasn't in a hurry. He focused his attention on his surroundings.

From the simple exchange just now, Klein roughly knew his opponent's basic situation.

His opponent should be able to turn invisible, and he was very clever at it. Furthermore, he could ignore the light and turn invisible.

He should be holding a dagger, and his attacks were very powerful. If his opponent was William, he was afraid that William wouldn't be able to withstand a strike from him.

Klein didn't have a good way to deal with such an existence.

The most important thing now was to force him to come out. Otherwise, if he was in the dark, it would be easy for the other party to find a flaw.

And Klein didn't dare to leave easily.

The other party could hide so well in such an open space. If he was in a dark place, he might easily fall for it!

Therefore, he had to get rid of him here!

Therefore, Klein focused his gaze and observed every movement of the flames.
