The night passed without a word.

The next day, Klein woke up very early.

He hurriedly washed up.

But to Klein's surprise, the two beasts were behaving strangely, as though their eyes were filled with fear.

"What's going on?"

Klein frowned as he muttered.

Suddenly, his eyes lit up.

'Could it be that the two beasts have suffered under my training for the past few days, causing them to have a shadow in their hearts?'

Thinking of this, Klein couldn't help but laugh.

The two beasts were usually lawless, but he never expected them to be afraid!

But it was true!

These two days, Klein could be considered to have trained with all his might.

And the two beasts were Klein's imaginary enemies.

In the beginning, the two beasts could still handle it with ease.

But in the end?

The two spirit beasts couldn't withstand Klein's bombardment at all.

After all, Klein's magic power had been charged by the magic core, and his magic reserves were very rich.

Even though he had used the lowest level of magic... But even so, the two beasts had been beaten to a pulp!

Thankfully, there were no pet lovers in the catacombs world. Otherwise, Klein would have made the headlines!

When the time came, a large group of people would come looking for trouble with Klein with signs of protest!

However, the benefits of doing so were very obvious.

The first to bear the brunt was Klein's understanding of magic.

This understanding included casting speed, casting control, casting target capture, and so on.

To put it bluntly, although the current Klein hadn't obtained much powerful equipment, he was still able to cast spells.

But after undergoing special training, Klein's strength had at least doubled.

If he were to meet the Armored Scorpion, Harpy, and Rogue Archer from back then...

Klein would definitely not be in such a sorry state!

...

After pondering for a while, Klein ignored the two beasts' gazes.

It was useless to try to placate them.

After all, after following Klein for so long, the two beasts had long been corrupted. It was a classic case of not letting go of an eagle until it saw a rabbit.

Klein estimated that to dispel their psychological trauma, a barbecue would be able to do it!

With this in mind, Klein shook his head.

It was still early, and lunch would be at noon.

Of course, Klein definitely wouldn't admit that he was lazy.

Otherwise, with the two beasts' appetites, it wouldn't be any easier for Klein to cook than to take down a tier 7 crypt creature!

Of course, Klein would never admit it.

If he were to ask, it would only be one word.

Busy!

Following that, Klein took out the Endless Sword.

According to the system's prompt, the Endless Sword could be powered up by runes.

Klein hadn't forgotten about it.

He only had more important matters to attend to, so he wasn't in a hurry.

In addition, the Endless Sword wasn't in a hurry.

After all, even if he used runestones to charge it, it wasn't something that could be repaired in an instant.

If it were that simple, it wouldn't be considered a divine artifact.

Upon thinking of this, Klein began to have doubts.

Back then, he had easily produced the divine artifact, the Endless Sword. Was there any other elemental influence?

The first thing to bear the brunt of it was his handsome face.

For such a handsome master, it shouldn't be too much to have a divine artifact, right?

The corners of Klein's mouth curled up.

Following that, the system prompt unfolded.

[Endless Sword (Epic)(Damaged)+8.]

[The materials required to repair it are as follows.]

[Each of the five runes requires 200 sets, but only 20% can be repaired.]

[The remaining 30% requires Cosmos Stones.]

As expected!

Klein swept his eyes over it.

200 sets?

He was slightly surprised.

This number was beyond Klein's expectations.

Back then, the synthesis of the Endless Sword only required 50 sets of five types of runes.

Now, it had increased by four times.

It seemed like his guess was right.

There was something behind the simple synthesis of the Endless Sword back then.

His looks were indeed the key element!

With this in mind, Klein nodded.

It was just that...

Klein took a glance at his backpack.

There weren't enough of them, and there was still a lot to go.

Although he had killed quite a number of crypt creatures and obtained a lot of runes during this period of time, he had also used a lot of them.

It seemed like he could only buy them.

Klein looked at his ingredients.

He still had quite a bit of Armored Scorpion meat.

But it was probably not enough.

After all, runes were hard currency in the catacombs world.

Many things needed them to be synthesized.

Furthermore, to increase his magic power, runes were the fastest and best way.

Therefore, runes were extremely precious in the catacombs world.

To an individual, it more or less wasn't enough.

With this in mind, Klein looked at his backpack again.

There were many things in it.

Most of them were materials.

But there were very few things to trade.

After all, things were no longer the same as before.

One had to know that back in the catacombs world, Klein had exchanged food and water for a large amount of supplies!

It was also at that time that it had laid a solid foundation for Klein's future.

However, he couldn't do it now!

Klein shook his head.

It was very difficult to exchange ordinary things for things.

However, Klein didn't lack ordinary things.

With this in mind, Klein looked at the Rogue Archer and Harpy outside the base.

As two tier 6 crypt creatures, although Klein had a mysophobia and didn't want to eat them...

They were, after all, tier 6 crypt creatures, and the blood and qi in their bodies were very large.

There were many benefits to having a large amount of blood and qi.

It could improve the physical qualities of low-level survivors.

It could also allow them to improve their magic talent.

Of course, the two benefits weren't that easy to obtain.

After all, it was just ordinary flesh and blood.

In order to achieve the effects of a special monster beast, one had to consume a large amount of it over a long period of time.

However, it was a good thing that he had enough of it.

Was one ton enough?

Klein looked at the two huge piles of corpses.

Although they weren't comparable to the Armored Scorpion, they were definitely not small in number.

With such numbers, as long as you persevered enough, even an idiot could bring you great benefits.

With this in mind, Klein went out to take care of the two beasts.

When he came in front of the two beasts, Klein was slightly astonished.

As expected, the world of the catacombs was wonderful. It hadn't been taken care of for two to three days, but the meat hadn't even gone sour!

In his previous life, two to three days was enough for the meat to give birth to many new lives!

Without further ado, Klein directly took out the Endless Sword.

That's right.

Ever since he had used it to cut the Armored Scorpions, he no longer had any interest in that rare weapon.

In comparison, rare weapons were like dregs.

Indeed, without comparison, there would be no harm!

However, if the Endless Sword had a soul, it would definitely protest.

After all, as a divine artifact in the catacombs world, it was a trump card!

However, it couldn't resist now.

Klein raised the Endless Sword and cut the two crypt creatures into sizes suitable for trade.

The process was very bloody, but thankfully, Klein was already used to it.

It was just hygiene!

Klein looked at the flesh that was covered in dust.

He felt a little guilty.

However, he instantly recovered.

After all, who wouldn't wash their meat?

How could they eat it if they didn't wash it?

They had to wash it anyway. There was nothing wrong with being a little dirty, right?

Of course, Klein didn't plan on managing the after-sales service.

At most, he would charge a premium for the transaction. Not only would they not be angry, they would probably praise him for being magnanimous!

With this in mind, Klein nodded.

Soon, he finished cutting the Rogue Archer as well.

After he finished cutting, Klein hung the ingredients in the trading hall.
