As soon as the system finished speaking, everyone couldn't help but curse!

"Oh my god, the crypt creatures have actually strengthened and the survival resources have decreased. This is troublesome. How are we supposed to play?"

"Damn Klein, it's all your fault. We're doomed."

"Can anyone save me? I'm being surrounded by seven or eight monsters. Damn it, how did they become so strong!?"

"Oh my god, three of my shovels are already broken. This wall is too hard!"

...

Compared to the unlucky ones, most people were more interested in the forging system.

Even Klein couldn't help but open the system to study it.

A forging system should be one that added equipment attributes.

This was very common in his previous life.

He just didn't know what the success rate of strengthening was.

Klein suddenly saw a question mark on the strengthening interface, and he clicked on it.

Strengthening+1, 100%]

[Strengthening+2, 80%]

[Strengthening+3, 60%]

[Strengthening+4, 50%]

...

The highest strengthening was 12, but the success rate was so low that it made one's hair stand on end!

Klein threw his Endless Sword in, and when he saw the souls he needed below, he nearly fainted.

He actually needed 50 souls!

'This is too much!'

Klein shook his head. He had no souls in his hands, so he couldn't try.

Turning off the system, Klein stood on the flat ground and felt the Endless Sword in his hand.

The energy contained in the Endless Sword was immense.

Klein estimated that this sword could increase his attack power by at least 80%.

In other words, if he encountered the Stone of Destruction again, he would be able to kill it with a single strike.

As for the door of defense, even that golden door wouldn't be able to withstand a single strike from him!

This wasn't the end. The Endless Sword could also provide an amplification for Klein's casting of spells.

Five types of spells could increase the strength by 50%.

Such an amplification was too terrifying.

Klein estimated that if he were to cast the Golden Spiral Shuriken, its lethality would probably be able to instantly kill the Stone of Destruction.

Even if the Stone of Destruction stood on the ground and used its strongest defensive door, it wouldn't be able to block it!

The above was just an increase in Klein's strength. If that was all, the Endless Sword wasn't considered the strongest weapon.

The most crucial factor was the final attribute. The Endless Sword could be magnified.

The degree of magnification was related to the user's own mana.

There was no upper limit.

In other words, as long as Klein's own mana was powerful, the Endless Sword would become infinitely large, and its offensive power would increase by a percentage!

Upon seeing this attribute, Klein sucked in a breath of cold air. He couldn't help but wave the Endless Sword in his hand and slash at the ground.

With a boom, the mountain, which was comparable to the eastern Pearl Tower, was directly cut in half by Klein's endless blade.

After it was cut in half, the additional attributes began to explode, and the entire mountain was instantly engulfed in a sea of fire.

"So powerful!" Klein couldn't help but exclaim in admiration.

This was twenty times stronger than the Golden Firestorm Saber!

It seemed like the Golden Firestorm Saber should be eliminated.

Klein took out the Golden Firestorm Saber and sighed.

After all, this was a weapon that had accompanied him for a very long time. He couldn't bear to part with it for a moment!

However, if the old wouldn't leave, the new wouldn't come. Klein put down his nostalgia and hung the Golden Firestorm Saber in the system's auction house.

The Golden Firestorm Saber was a powerful weapon. Although he didn't need it, to everyone in the catacombs world, this weapon was definitely equivalent to their divine artifact.

With this weapon, their efficiency in farming monsters would definitely increase by a few times, and their chances of survival would also increase by a few times.

After putting it up for auction, Klein started bidding at 200 souls before ignoring it.

However, what Klein didn't know was that his Golden Firestorm Saber had caused a huge uproar in the catacombs world.

"What is this thing? It's actually so expensive?"

Some people couldn't help but be curious when they saw the first-ranked weapon in the auction house.

After casually clicking on it, he was immediately shocked when he saw the properties of the Golden Firestorm Saber!

"Oh my god, this is a divine artifact, right? Who's so stupid as to actually sell it?"

The person clicked on the auctioneer. When he saw Klein, the corners of his mouth curled up as he hurriedly looked around, afraid that his words would be spread!

"No wonder. After all, Lord Klein has the Endless Sword, so this Golden Firestorm Saber naturally won't be of any use. But just how powerful is the Endless Sword to make Lord Klein give up on such a powerful weapon?"

That person couldn't believe it!

There were many people who had the same thoughts as this person.

But even more people chose to make an early move.

The price was quickly raised.

It went from 200 souls to 300 souls, and it was still increasing at a rapid rate of 10 souls.

This number was very terrifying in the auction house.

Most weapons didn't have more than 50 souls.

And souls were also very important strategic resources in the catacombs world, so their prices were very expensive.

Therefore, the fact that the Golden Firestorm Saber could be sold for such a price showed the strength of the weapon from another angle.

Someone thought for a moment before saying, "Is there a brother who can lend me 50 souls? I must get this divine artifact!"

"Hmph, once I have this weapon, I'll be invincible in the catacombs world. By then, I'll definitely be able to develop to the level of God Klein. Who wants to invest in me?"

"I'm ranked second on the rankings. As long as you give me this Golden Firestorm Saber, I'll definitely be able to catch up to Klein. When the time comes, I'll give you endless benefits. Don't fight with me."

"Hmph, this weapon is so powerful. Anyone can become a god. Why should I give it to you? You want to use your strength, which is ranked second?"

"That's right. I'll definitely take this Golden Firestorm Saber!"

"Whoever dares to snatch it from me, I'll definitely kill them when I see them!"

...

The auction house was in chaos. The intense competition had directly raised the price of the Golden Firestorm Saber to a sky-high level.

As for the instigator, Klein didn't know that he was sitting in front of the table, enjoying his food while thinking about his next move.

After he finished eating, he washed the dishes and rested outside the house for a while.

He had to admit that the environment of the catacomb was really good. He didn't know where the wind came from, but it was actually so comfortable.

Furthermore, the air was very fresh, and there was actually a slight sweetness to it.

The only shortcoming was that there were no stars at night!

After resting, Klein returned to his bed and opened the system. At that moment, the auction for the Golden Firestorm Saber was also completed.

Klein opened the auction house to see if there was anyone who knew what was good for them.

But when he saw the bid, Klein was stunned!

The number of souls bid had reached 570!

'Oh my god, where did these people get so many souls?'

After all, there were only one or two souls in each catacomb. How many would it take to gather so many souls?

Klein shook his head and didn't probe further. To him, having souls was the most important thing.

Then, he pressed a button to collect the souls from the auction.
