The half-step natural disaster that had grown up had already increased its speed.

Although it still didn't look fast from where it was standing, just think about it. The internal wind speed of the half-step natural disaster had reached 280 meters per second.

The range of deterrence had reached 700 meters.

Although its speed was only a tiny 30 kilometers per second, with such a terrifying attack range, no land could withstand it wherever it passed.

Everything was overturned one after another.

As for the majority of the Mogonia Flying Dragons, although they had long sensed the half-step natural disaster, they had already slowly turned around and fled in the air.

But unfortunately, their race was simply too large.

It was simply impossible to turn around in a short period of time.

Thus, all the Mogonia Flying Dragons could only slowly enter the half-step natural disaster.

Once they entered, they would be mercilessly killed, leaving no bones behind.

As for the crypt creatures on the ground...

[Parepos Sand Knight, Corpse, Tier 5]

[Advantages: Extremely high HP, extremely thick shield, far surpassing most tier 6 crypt creatures.]

[Disadvantages: Extremely slow, low damage, very easy to be kited.]

[Pitchfork Cave Dweller, Corpse, Tier 5]

[Advantages: Powerful attack. Has the ability to advance.]

[Disadvantages: Extremely difficult to get close to. Not fast. Once you dodge the advance, it's easy to be kited to death.]

[Peirce Sand Worm, Corpse, Tier 5]

[Advantages: Long-range attacks. Attacks are very concentrated.]

[Disadvantages: Extremely slow, extremely defensive.]

...

The system prompted Klein to take a closer look.

After reading it, Klein couldn't help but break out in a cold sweat.

Thankfully, he had summoned a half-step natural disaster in advance. Otherwise, once the monsters on the ground approached, Klein would definitely have no way of surviving.

Not only were there the Parepos Sand Knights who acted as meat shields, but there were also the Pitchfork Cave Dwellers who acted as warriors. There were also long-range attacks, and they were the Peirce Sand Worms that covered the attacks.

Once they got close, even the Peirce Sand Worms' long-range attacks would be enough to make him suffer.

But thankfully, these crypt creatures would eventually become the food of a half-step natural disaster.

...

Soon, the crypt creatures in the sky and below engaged in a fierce battle with the half-step natural disaster.

Among them, only the Parepos Sand Knight could withstand it for a few seconds. The rest of the crypt creatures couldn't withstand it for even a second, and they were instantly chewed to death by the half-step natural disaster.

As for the Parepos Sand Knights, although it could withstand it for a few seconds, it was in an extremely miserable state. It constantly charged forward in an attempt to charge past the half-step natural disaster tornado and kill Klein.

However, as it took a step forward, a portion of its flesh and blood was reduced. When it was about to break through the half-step natural disaster, the flesh and blood on its body had already disappeared, leaving behind only its bones.

The bones didn't last long before they were quickly crushed by the gravel in the half-step calamity realm and completely disappeared.

...

After an unknown period of time, the number of crypt creatures in the sky and on the ground had visibly decreased.

As for Klein's half-step calamity, the color of his blood had also thickened.

The wind inside had finally reached the limit of a true calamity, 299 meters per second.

Sensing the speed of the natural disaster, Klein frowned and thought to himself, '299 meters per second. It's already been half an hour. Why can't I break through?'

'Could this be a hurdle? Only a breakthrough is a true natural disaster?'

'Then how do I break through?'

Klein frowned. He didn't have any good ideas at the moment.

Perhaps he had to wait until his strength rose to another level.

Another hour passed, and the crypt creatures were completely wiped out.

No living creature could be seen with the naked eye.

The half-step calamity that had lost its target stopped at the moment. It was still spinning rapidly, as though it was thinking of how to break through to become a true calamity.

At that moment, the system's notification suddenly appeared.

[Half-Step Natural Disaster Whirlwind (Peak) has already reached the limit of a half-step natural disaster. However, due to the limited power of the internal magic core, it can only grow to this level. There is no chance for it to advance.]

[After killing a large number of creatures, the Half-Step Natural Disaster Whirlwind has already absorbed a terrifying amount of flesh and blood. Although it can not be upgraded to a real natural disaster, it can bring a great medicine that can nourish the flesh and blood of the host.]

[The required ingredients are: A large number of various runes and souls. The more there are, the higher the probability of producing a great medicine to nourish the flesh and blood. It will also affect the quality of the great medicine produced.]

Looking at the notification in front of him, Klein was taken aback.

He couldn't help but ask, "Great medicine? To nourish the flesh and blood?"

Immediately, a smile suffused Klein's heart.

If his guess was right, the flesh and blood should be a medicine to increase his strength.

Such things were extremely precious.

Previously, when Klein sold the tier 6 crypt creatures, the Harpy and the Rogue Archer, he had caused a stir in the catacombs world trading hall. Furthermore, he had sold them at an extremely high price in a short period of time.

Why did they like it so much?

Why did they pay such a high price to buy it?

Was it because they were bored?

Was it because they wanted to get to know Klein?

Of course not.

This was because the stronger the flesh, the greater the effect it had on his three measurements, physical strength, magic talent, and so on.

For example, the Armored Scorpion that Klein had eaten previously gave him a considerable increase in his three measurements.

And compared to the flesh from before, although the level of the flesh in front of him wasn't high, there was a lot of it.

Although Klein didn't know the exact number.

However, it took a full few hours for a half-step natural disaster to kill these demonic beasts. Furthermore, the area it covered was more than seven hundred meters. How many of them were there?

Klein estimated that there were at least a few million of them?

With such a terrifying number, even if it was a tier 1 crypt creature, the blood and qi that would be nurtured after it became a great medicine would probably be extremely terrifying!

With that, how could Klein not be tempted?

Thinking of this, Klein sucked in a breath of cold air. He couldn't help but lick his dry lips and say, "I've earned it, I've earned it, I've really earned it!"

Compared to the flesh medicine, runes and souls weren't that important.

Although a large number of runes could increase Klein's magic reserves, he knew that if he wanted to increase it, he would need a huge amount of elemental runes. Furthermore, the amount of increase was much less than the magic core.

And compared to the flesh medicine in front of him, it wasn't even enough.

This was because Klein had always believed that the body was the foundation of everything.

Only when his body became stronger could Klein control more powerful spells and withstand more powerful damage.

It wasn't like now. Although his attack power was powerful and he could easily control a tier 7 or 8 crypt creature, once these crypt creatures took the opportunity to attack his body, Klein wouldn't be able to withstand it.

Therefore, the flesh and blood this time was no less of a surprise to Klein than the divine artifact, the Endless Sword!
