After Klein extracted his souls, he didn’t care who had the Golden Firestorm Saber in their hands. He directly opened the forging system and began strengthening the Endless Sword.

Klein placed the Endless Sword on it and threw 50 souls into it. The strengthening machine began to move, producing a whimpering sound.

Soon, the strengthening was completed. A white light flashed, and the Endless Sword successfully 1.

Klein took out the Endless Sword and checked his attributes.

Under the attack column, he actually received a percentage increase in true damage.

Although it was only a tiny 1%, it still depended on who had it.

In Klein’s hands, this 1% true damage was a terrifying number.

As for the other attributes, they didn’t change.

Klein continued throwing the Endless Sword to strengthen.

Strengthening successful: Endless Sword 2

Strengthening successful: Endless Sword 3

Strengthening failed: Endless Sword 2

Strengthening successful: Endless Sword 3

…

After strengthening for half the night, Klein used up all the souls in his hands.

Looking at the Endless Sword, the current Endless Sword 8.

The true damage reached 40%.

Klein was very satisfied with the result.

But when he looked at his balance, his mouth couldn’t help but dry up!

There wasn’t a single soul left of the 850 souls!

As expected, the Tieba in his previous life was right. Strengthening would ruin his life.

Thankfully, Klein had a rich family background. Otherwise, he wouldn’t have been able to hold on for so long.

Klein took out the Endless Sword, and suddenly, the system’s system notification rang once again.

Congratulations to the number one combat strength, Klein, for successfully strengthening Endless Blade 8.

When the news came out, everyone was shocked.

At the same time, forging was once again hyped up.

Many people tried it one after another, hoping to defy the heavens and change their fate.

However, not everyone was as rich as Klein. Many people went bankrupt and lost everything.

Of course, none of this had anything to do with Klein.

After Klein took out the Endless Sword, it emitted a faint glow.

Its power had also increased by 50%.

Klein was very satisfied. He kept it, put it in his backpack, and fell into a deep sleep.

…

The next morning, Klein woke up very early.

After hurriedly packing up, he began the next round of challenges.

When he arrived at the cave’s barrier, a system notification appeared.

You’ve finally arrived here. Behind this cave is the terrifying King of the Catacombs, Raksha. Are you really prepared? Or could it be that you’ve lived enough and want to face death directly? Raksha’s power comes from darkness, and it’s also very afraid of light. If it encounters light, Raksha will die a tragic death.

Looking at the system’s notification, Klein was taken aback.

The notification this time was much more detailed.

King of the Catacombs?

What a powerful title!

It seemed like he was the source of breaking through the limitations of the catacombs.

Klein gripped the Endless Sword and took out a shovel to begin digging the catacomb.

…

The catacomb here was very hard. Klein had to dig for half an hour before he succeeded.

He walked in and was immediately surrounded by endless darkness.

His surroundings were as black as ink, and he could even vaguely see the shape of the flowing darkness.

Klein took out the Endless Sword.

The faint light from the Endless Sword dispelled the darkness, making Klein feel much more at ease.

Following that, Klein cast a fire spell, and large swaths of flames spread out, illuminating the pitch-black space.

The entire space was desolate.

It was different from the desolation of the Blood Ape or the space where the undead Ghoul lived. It was a desolate emptiness.

Even if you stood there, you would feel every piece of soil, every withered leaf, and every hut that filled the world was filled with despair.

It was as though something terrible had happened here. Countless people had died with unwillingness and despair, forming such an evil land.

That’s right. Even someone as strong as Klein could feel the despair that numbed his scalp as he stood there.

“Despair?” Klein muttered.

He couldn’t help but recall the information he had found in the room beside the stone statue when he entered the cave.

It seemed like there had indeed been a terrible massacre.

Could it be this place?

Who was the only survivor?

Could it be Raksha?

It couldn’t find a way out here and had survived for so many years?

Klein shook his head and didn’t dare to guess further.

Then, he continued walking forward.

It was a dilapidated mountain. The mountain was extremely huge. Klein took a cursory glance, and from afar, it looked even bigger than the Himalayas.

However, it was such a huge mountain that had been split in half by something.

Klein stood at the crack, and a shocking killing intent emanated from it.

He didn’t know what was so powerful that it could split such a huge mountain into such a state!

Klein continued walking, walked through the jungle, and arrived in front of a village.

The village was very dilapidated, and the entrance to the village was already in ruins. Klein stretched out his hand and pushed it open. The door creaked, making one’s teeth hurt.

After entering, Klein was stunned by everything inside.

There were countless skeletons inside!

These skeletons had long lost their corporeal bodies. Their pale white bones gave off a cold glow under the light of the fire.

The skeletons were stacked together, layer by layer, densely packed. The soil beneath the piles of skeletons had long been dyed black, but strangely, there were no weeds inside.

‘What on Earth happened here?’

Klein couldn’t help but feel a chill run down his spine.

There were just too many white bones in front of him!

How many people had died back then?

There were no roads around, and the only road was also blocked by the white bones. Klein cast a wind spell and flew over.

At one end of the existence was a huge pot. There were even more bones stacked beside the pot.

There were also quite a number of bones in the pot.

Under the pot, there were also quite a number of half-burned bones.

An ominous feeling filled Klein’s heart.

He had guessed something, but he wasn’t sure!

If that was really the case, it would be too terrifying.

Then, he continued walking forward, passing through the village and arriving at the peak of the mountain.

The peak of the mountain was very lush. There was a platform, and on the platform was a stone statue.

The stone statue knelt on the ground and didn’t move, as though it was atoning for its sins.

In front of the stone statue was a table. There were two candles on the table, and they seemed to be stones as well.

Klein walked up and stood at the peak of the mountain, wanting to look outside.

There were more mountains outside, but they were nowhere near as tall as the one he was standing on.

Just as Klein was about to leave, a gust of wind blew past, and the two candles on the stone platform inexplicably lit up.

The light from the candles was green. The flame wasn’t very bright, but it instantly lit up the darkness of the cave. In an instant, the world turned green.

Klein couldn’t help but look back. The village had actually disappeared!
