Klein had a deep memory of that attack. If not for the Golden Spiral Shuriken, he would have been reduced to a pile of bones by now!

With the Stone of Destruction, he would have the ultimate killing intent in his hands.

At that time, he wouldn't have to be so uncertain when facing Raksha.

After all, its subordinates were so strong and difficult to deal with. Wouldn't it be even more terrifying in person?

As for the warning from the Golden Finger, Klein believed it.

However, it was definitely not that simple.

After all, he was the boss of the catacomb. How could he die so easily?

Following that, Klein took out the Earth Dew.

[Earth Dew. Allows the user to rapidly recover 30% of his HP and Mana.]

Hiss--

The introduction was simple and crude, but the effect was excellent.

It was especially effective for rapidly recovering 30 HP and mana.

This gave Klein the ability to delay the battle.

Putting everything aside, if he had this item in his final battle against the Stone of Destruction, he could have just drank a bottle and casually killed the Stone of Destruction seven or eight times. How could he delay it for so long?

Furthermore, recovering 30% of his HP could completely save his life. If he used it well, it was equivalent to having two lives!

Klein put away the items and recovered some mana. Then, he looked at Lehman, who had collapsed into a ball.

He had seen this person when he entered the cave.

Back then, it had been too difficult to fight against the Stone of Destruction, so he hadn't noticed him.

He didn't expect that he would dare to follow him. He was really courting death!

Klein slowly walked over and saw the person lying motionless on the ground, as though he had fainted.

Following that, Klein took out the Golden Firestorm Saber and used its characteristic to extend it, flipping the person over.

After flipping the person over, there was a huge hole in the person's chest. Clearly, he had died from accidental injuries while the Stone of Destruction was casting a spell!

Upon seeing this scene, Klein couldn't help but shake his head.

Although he didn't know if this person had other thoughts, he had died a tragic death!

This saved him some effort. He had already warned this person that even if he wasn't killed by the Stone of Destruction, Klein would still kill him!

After all, his battle didn't allow anyone to disrupt it!

Today was definitely not the day for a battle, so Klein opened his base and walked in.

This battle had really drained him of all his magic. At this moment, his mind was in a daze, and he just wanted to find a place to rest.

Klein touched the side of the bed and, ignoring the sound of Little Wind and the Little Fox, fell asleep.

He slept very comfortably in this dream.

In his dream, he dreamed of the scene after he went out.

...

When he woke up, it was already the morning of the third day.

Klein opened his eyes, looked at the familiar things in front of him, and felt relieved.

Then, he prepared to stand up, but Little Wind and Little Fox had fell asleep beside him.

Klein gently put them down and stood up. Looking at the fruits prepared by the table, he couldn't help but feel a little comfortable.

Although it was simple and crude, it still made Klein feel the care and concern of the two creatures.

He casually picked up one and ate it. As he ate, he walked to the kitchen.

He made some simple food to fill his stomach, and then he went to the forging room.

He took out the blueprint of the Endless Sword that he had obtained previously.

At this moment, the blueprint was still short of twelve souls and a few runes.

Klein extracted the souls he had purchased and then released the purchase of runes.

In the afternoon, Klein's materials were also gathered.

This time, he didn't level up in his base. Instead, he went outside.

After all, it was the most powerful artifact in the catacombs world. God knows what special things would happen?

After arriving outside the castle, Klein put away the base and took out the blueprint of the Endless Sword.

[Blueprint of the Endless Sword able to meet the demand. Would you like to forge it?]

Klein chose [Yes].

Soon, the blueprint emitted a scorching heat in Klein's hands.

Klein hurriedly released it.

Then, the Endless Sword Blueprint flew into the sky.

The runes and souls in Klein's backpack flew out and actively fused with the Endless Sword Blueprint.

After absorbing it, the Endless Sword Blueprint emitted a dazzling light in the air.

Klein looked over. Amidst the endless light, he saw the embryonic form of a sword.

This sword was very strange, regardless of its color or body.

The color alternated between green, gold, yellow, and red...

Sometimes it was multicolored, and sometimes it was dull and lusterless.

The body of the sword was very large, like a longsword from the Middle Ages. The armguard in front of the hilt was very long, and it was a wide-hilted sword.

Soon, the light from the Endless Sword dimmed considerably.

The three mysterious souls in Klein's backpack seemed to be attracted as they struggled to charge at the Endless Sword.

After the fusion, the Endless Sword was completely formed. The color of the sword had also completely stabilized. It was black as a whole, but there were countless strange patterns in the black. The patterns were golden.

Upon closer inspection, the golden patterns seemed to be flowing. It was extremely mystical.

The sword body finally had some changes. The hilt's armguard wasn't as wide anymore, and the sword body was longer. It was about 1.5 meters long.

The light from the Endless Sword dissipated, giving off a powerful deterrent in the air.

At that moment, a notification from the server across the entire channel sounded.

[The number one combat power in the catacombs world, Klein, has successfully produced the strongest artifact in the catacombs world, the Endless Sword!]

Everyone was shocked when the news was released!

"Endless Sword? Heavens, what on earth is it? It's actually known as the strongest artifact in the catacombs world?"

"It's Klein again? Heavens, just how powerful is this person? Damn it, it must be a good item dropped by the boss later on. Unfortunately, that damned Earth Rat Lehman didn't turn on the livestream!"

"How enviable! I can imagine that the catacombs world has no more obstacles for Klein."

"Why isn't it mine? The system isn't fair."

"I'm willing to use my ten years of life in exchange for an Endless Sword in the catacombs world."

...

Klein looked at the system notification and was stunned. He didn't expect the system to say such a thing.

However, it didn't matter. With his current strength, he wasn't afraid of anyone. Whoever came would die!

And at that moment, the system's voice sounded once again.

[As Player Klein has obtained the strongest divine artifact in the catacombs world, the strength of the crypt creatures has been increased by 1, the drop rate has been increased by 1, the survival resources-1, and the strength of the catacombs world's barrier has been increased by 1]

[As Player Klein has obtained the strongest divine artifact, Endless Sword, his achievement has been achieved, and he has activated the forging system.]

[The forging system can increase the level of the equipment. For every level increase, the equipment will receive a certain amount of attribute enhancement. Please try the specific data yourself.]
