At first, Klein thought he was seeing things.

Therefore, he rubbed his eyes and looked over again.

When he saw that it was really gone, Klein couldn't help but nod.

As expected!

He had underestimated the importance of epic-grade weapons to them!

And from the looks of it, it was likely that they had completely gone off the shelves not long ago.

This made Klein shake his head involuntarily.

Why?

Wasn't it because he had underestimated the financial strength of low-level survivors?

At first, he thought that it would be difficult to gather more than three hundred wind runes.

After all, they couldn't control the crypt creatures to drop anything.

But he didn't expect that after such a long period of accumulation, most of them were hidden.

If he really obtained something good, they would immediately step forward and purchase it!

With this in mind, Klein couldn't help but shake his head and didn't pursue the matter any further.

Then, he opened his backpack and looked at it.

When he saw the wind runes inside, Klein was shocked.

There were forty to fifty thousand wind runes inside.

The amount should be enough.

Then, Klein took out the Runic Devouring Ticket and clicked to learn.

In an instant, the talisman of devouring runes appeared in the forging blueprint library.

Klein came to the forging room, found the devouring runes, and placed all the wind runes inside.

Hum--

The sound of forging suddenly sounded.

Countless runes were transported along the forging pipe to a huge oven.

When the runes were thrown in, the oven suddenly burst into flames.

The flames instantly burned the countless runic blobs.

Before long, the countless runes disappeared at a speed visible to the naked eye.

What appeared next was an extremely pure magical element.

[High-grade initial elemental particles. The wind element within is extremely dense. Once touched, it will completely assimilate the host.]

Klein was extremely shocked when he sensed the wind element within.

When he saw the system's notification, he frowned.

As expected!

He had seen the initial elemental particles before.

The Endless Sword in his hands had become so powerful because he had the initial elemental particles.

It was only because he had exhausted the initial elemental particles while suppressing a mutated half-step natural disaster that the quality of the Endless Sword had dropped. It was still unable to be repaired.

However, what Klein didn't expect was that the initial elemental particles were so domineering.

They could actually assimilate into people.

Thankfully, he wasn't greedy and took it out. Otherwise, he would've been in great trouble.

Soon, the initial elemental particles finally absorbed enough wind runes as their bodies suddenly trembled.

Following that, they emitted a green light.

The light was extremely dazzling as it instantly penetrated the forging room.

If someone were to watch from the outside, they would definitely be shocked because the entire forging room seemed to be surrounded by a faint color.

From afar, it looked like a haunted house at night.

At that moment, the two beasts were alarmed.

They hurriedly ran over.

Little Wind grabbed Klein's pant leg and stared intently at the elemental particles in the forging room.

As for Little Fox, she was lying on Klein's shoulder, revealing half of her head as she looked, her body trembling slightly.

Clearly, the power of the elemental particles was extremely terrifying to the two beasts.

It was to the point that they were extremely afraid.

That was indeed the case!

The original elemental particles were probably the purest wind elements in the catacombs world.

The power was naturally very great.

And at that moment, the forging room underwent another change.

The ball of faint wind elements suddenly split apart in the middle.

It split into five strands.

In the air, they turned into small snakes the size of a pinky finger.

The color of the small snakes was even darker, like a pool of lake water.

At first, the elemental particles separated in the air and then turned into small snakes. Following the pipes of the forging room, they came to a page of the composition diagram.

"It's almost done!"

Klein stared at the composition diagram, and he couldn't help but feel excited.

He didn't know how much of a magic boost the initial elemental particles would bring him!

Then, the five small snakes were sucked into his body by the synthesis diagram.

In an instant, the magic patterns on the synthesis diagram seemed to have been energized, and faint colors quickly spread along the magic patterns.

Before long, the entire magic pattern was completely lit up.

Soon, countless faint lights converged in the middle of the magic pattern along the exit of the pattern.

They formed a gigantic ball.

From afar, the ball looked even greener. It was like Naruto's spiral shuriken from Naruto.

And from a closer look, the violent wind on the spiral shuriken was wantonly struggling, trying to escape the control of the forging room.

Klein frowned slightly as he sensed the wind spreading within.

The power of the wind was immense. If it was in the outside world, it would be at least as powerful as his half-step calamity.

Furthermore, due to its purity, its potential for growth was even greater.

Klein had a guess that his growth could break through the final step of the half-step calamity!

Soon, the ball in the middle of the blueprint grew larger and brighter, and finally, there was a pop.

After it solidified, it floated out of the forging room.

Klein beckoned with his hand, and the magic ball flew towards him.

At that moment, the system's notification appeared.

[The pure wind elemental core is extracted from the original elemental particles. It's the most gentle elemental power. Once absorbed, it can increase the host's wind affinity by 100%.]

Klein swept through the system's notification.

Immediately, a look of joy appeared on his face.

'100% affinity with the wind attribute?'

'That's great!'

'But how do I absorb it?'

Klein was in a dilemma.

Then, he looked at his head, made up his mind, and stuffed it into his mouth.

Boom--

Instantly, the wind elemental core that entered Klein's body turned into the purest elemental power. It sliced open Klein's mouth and washed his entire body.

The two beasts were forced back by the huge magic fluctuation.

There was nothing they could do. At that moment, Klein's entire body had undergone a drastic change after eating the wind elemental core.

From afar, it looked like he had stuffed down a light bulb.

The light bulb was green.

Therefore, it made Klein's entire body emit a faint light.

The faint light was only in his mouth at first.

But soon, it separated from his mouth. One went up and the other went down. Soon, it completely enveloped Klein.

At that moment, the light on Klein's body grew even brighter.

Not only that, even the wind elements around him seemed to have sensed the most delicious thing in the world as they rapidly pounced on Klein.

The terrifying speed caused the space around Klein to emit a whirring sound.

Clearly, the speed at which the wind element was absorbed was too fast, causing the entire space to undergo a mutation.

However, Klein didn't know what was happening in the outside world.

The system's notification sounded once again.

[The wind element is in a riot. The host must use the wind element core to plant it on his spine. Otherwise, the wind element that has nowhere to be placed will cause the host to burst!]
