Therefore, Klein began to invest a large amount of resources.

He threw in all the hundreds of souls he had just collected.

He also threw in all the hundreds of runes he had collected previously.

He didn't even blink.

But it still didn't seem to be enough.

Klein saw that the half-step calamity in front of him was of no use, and he knew that he still hadn't invested enough.

Then, Klein directly summoned Little Wind and Little Fox.

He told them about the current situation.

The two beasts couldn't understand why Klein's magic was so magical.

After reacting, they began collecting the runes and souls that had exploded in the entire space.

As for Klein, he began collecting them in the area behind the half-step tornado.

Soon, the soul and runes in Klein's backpack began to enrich at a speed visible to the naked eye.

100 portions.

300 portions.

800 portions.

1,000 portions...

But the amount collected was still just a drop in the bucket when compared to what had exploded in the cave.

...

Klein, Little Wind, and Little Fox collected for about half an hour.

The number of souls reached 10,000.

The number of various types of runes also reached about 5,000.

Seeing that he had collected enough, Klein threw the runes and souls into the tornado.

After all, who knew how long a half-step tornado could last?

If it ended early, he would be at a huge loss.

The amount Klein had invested this time had successfully caused a change in the half-step tornado.

The most obvious thing was that the death of the half-step natural disaster tornado had been greatly reduced, and it was now overflowing with life.

Not only that, the originally stinky half-step natural disaster tornado was now emitting a hint of sweetness.

However, it was very faint. Only Klein, as its owner, could smell a hint of it.

This hint was very important.

It allowed Klein to know that the half-step natural disaster's tornado was producing the great medicine the system was talking about.

Therefore, he couldn't be bothered with anything else and collected it again.

Soon, half an hour passed.

Klein, Little Wind, and Little Fox collected tens of thousands of ingredients and quickly threw them into the collection.

The vitality of the half-step natural disaster surged once again, and the strange fragrance began to intensify. Even the two beasts could smell it.

Without having the time to sigh, Klein, Little Wind, and Little Fox once again threw themselves into the collection process.

...

The man and the two beasts busied themselves from morning till night.

At first, they were still counting with great interest, but in the end, the amount they obtained was just too great. In the end, they were completely numb.

They became the most primitive robots, numbly picking up souls and runes.

At this moment, there were very few souls and runes left in the entire space.

After a few hours of looting, they were finally done.

Klein looked at the last batch of souls in his backpack.

38,000 souls.

1,984 runes of various types.

And at this moment, the tornado of a half-step natural disaster had reached its final stage.

The rich medicinal fragrance could no longer be suppressed as it circulated in the space.

As for the half-step natural disaster tornado, it had also changed its appearance.

The bloody scene outside had completely disappeared, revealing the true appearance of a half-step natural disaster.

It was purplish-black.

Upon seeing this, Klein nodded and thought to himself, 'It's about time.'

If it weren't for the fact that there are so many souls and runes in this space, he wouldn't have been able to support the nurturing of this great medicine.

"Perhaps it can't be said that way. It should only be possible if all the runes and souls in the entire catacomb were added together!"

Following that, Klein waved his hands, and the runes and souls in his backpack automatically flew in.

At this moment, Little Wind and Little Fox also sensed something and quickly came in front of Klein.

Looking at the two beasts in front of him, Klein reached out and rubbed them.

They had really worked hard this time!

The numbers this time were extremely large. If he were to rely on himself, even if he succeeded in refining the final great medicine, he would be exhausted to death!

The two beasts didn't say a word, but their eyes were fixed on the inside of the tornado.

As spirit beasts, they were very sensitive to changes in the outside world.

Seeing the half-step calamity turn into such a state, they knew that they were almost there. They were almost there!

Indeed.

When Klein threw the last batch of materials into the tornado... There was the sound of a treasure.

Boom!

The entire half-step calamity shook.

The tornado, which had originally reached 299 meters per second, slowed down at a speed visible to the naked eye.

Once the tornado slowed down, it would be difficult to lock down the medicinal fragrance inside.

Soon, the medicinal fragrance began to spread at a speed visible to the naked eye.

...

After about half an hour, the tornado's speed had dropped to 100 meters per second.

At this speed, Klein could roughly see what was happening inside.

Inside the purplish-black tornado, a blood-colored pill was slowly rotating with the tornado's speed.

The speed of the light it brought with it also became brighter.

"Squeak--"

Little Fox let out an excited cry.

Little Wind was also extremely excited as he replied, "It's really going to happen!"

"Heavens, with so many demon beast corpses, how terrifying is this one? If you eat it, it'll probably make master become a god!"

"I don't know, but it's definitely not weak. At the very least, its physical body isn't inferior to a tier 8 crypt creature!" Little Wind said in shock.

Klein naturally didn't know what the two beasts were talking about.

But at that moment, his heart couldn't help but beat.

With such an opportunity, no one could calm down.

...

Time slowly passed.

The half-step natural disaster tornado finally slowed down.

Pa!

There was a crisp sound.

The half-step natural disaster tornado finally couldn't hold on any longer.

It instantly disintegrated in the air.

After losing the wind pressure of the tornado, everything inside began to collapse frantically.

This included the large medicine.

Klein naturally wouldn't let the large medicine fall to the ground.

Therefore, he hurriedly activated the Explosive Speed of his shoes and frantically grabbed at the large medicine.

Before long, Klein held the large medicine in his hand and retreated, successfully landing on the spot.

Looking at the large medicine in his hand, Klein was extremely excited.

Soon, the system's notification appeared.

[Flesh and Blood Medicine (Epic)]

[Effect: It can greatly enhance the bloodline.]

[Remark: The enhancement of the bloodline can not only strengthen the body, but it can also increase the talent of magic, the storage of magic, the release of magic, and so on.]

Looking at the notification in front of him, Klein nodded slightly.

It was actually an epic-level treasure.

And the enhanced bloodline could actually give him such a huge increase!

Once he obtained an increase, his strength would definitely increase by a few levels.

'Now, I have more confidence in dealing with the Poison Dragon!'

With this in mind, Klein took a gentle sniff of the Blood and Flesh Medicine.

The bloodline in his body began to move crazily, constantly telling Klein that it needed it!

Klein no longer hesitated, and he threw the Blood and Flesh Medicine into his mouth.

Instantly, the Blood and Flesh Medicine exploded in Klein's mouth
