And at this moment, the Intermediate Whirlwind that had broken out of its shell was growing at a speed visible to the naked eye.

Feeling the power of the Intermediate Whirlwind, Klein couldn't help but nod.

'It's indeed useful. Furthermore, after I improved it, not only did I consume less magic, but I also grew much faster. I just don't know how powerful it is?'

Klein never let go of the Whirlwind spell.

This was because the benefits of the Whirlwind spell were very obvious to Klein.

Not only did it help Klein deal with many powerful enemies, such as the three at the platinum treasure chest, the Traitor Zekos, and so on, but it also helped him obtain nearly a million demon beasts.

Most importantly, it helped Klein obtain many treasures that ordinary people couldn't imagine.

For example, the original magic core, the Blood Essence Medicine, and so on.

Therefore, regardless of what it was, Klein couldn't bear to leave the Whirlwind spell behind.

Furthermore, he guessed that the potential of the Whirlwind spell wasn't limited to that. Once he broke through to a half-step natural disaster, it was very likely that it would give Klein a powerful surprise.

Of course, these were secondary. Klein saw that the Intermediate Whirlwind spell in the sky had finished accumulating.

Hence, he controlled them to scatter in all directions.

They stood in front, back, left, right, up, and down positions.

Of course, the process wasn't very smooth either.

After all, Rakshasa was currently surrounded by the explosion caused by Klein's Vacuum Strike.

The explosion wasn't just caused by Klein's Vacuum Strike. It was also caused by Rakshasa's own magic. Therefore, the explosion that resulted had exceeded Klein's expectations.

Therefore, just as Klein was distributing the Whirlwind spell and trying to expel the flames of the explosion in front of him, the heaven and earth elements stirred by the Whirlwind spell actually caused countless violent explosions in a short period of time.

The power of the explosion was extremely terrifying. Klein estimated that even he wouldn't be able to withstand a few of them.

However, due to the evolution of the Whirlwind spell, he was able to withstand it.

This made Klein unable to help but look delighted.

He thought to himself, 'The growth of the Intermediate Whirlwind has indeed exceeded my expectations.'

Then, after a few Intermediate Whirlwind spells were cast, Klein stopped and stood where he was. He held the Endless Sword in his right hand and placed it on his chest. The tip of the blade was facing up, and the hilt was facing down.

Then, the magic in his body rapidly surged towards the Endless Sword.

After absorbing Klein's own magic, a gray substance appeared on the Endless Sword.

From afar, it looked like a thin mist.

It was as though it would be blown away in the next second.

However, Klein knew very well that this was the key to controlling the Intermediate Whirlwinds.

At first, Klein wasn't very clear, but after a few attempts, Klein felt that the core of the Intermediate Whirlwinds that flew out was the magic that Klein had originally supplied.

Therefore, the gray weapon on the Endless Sword was created to communicate with the Intermediate Whirlwind spell.

This situation could be understood as the difference between a remote control and a television.

Both sides spread out a low-frequency signal so that the television could follow the instructions of the remote control.

After learning this, Klein was very happy.

This control allowed him to control the Intermediate Whirlwind more easily, such as now.

Klein calmed his heart and used the thick fog on the Endless Sword to sense the six Intermediate Whirlwinds.

At this moment, in Klein's perception, the Endless Sword in his hand had turned into nothingness, but the light on its body was becoming brighter.

This light was a signal to receive and control the Intermediate Whirlwinds.

Therefore, Klein used this signal to contact the other Intermediate Whirlwinds.

In his eyes, there was a fist-sized, very dense magic core at the core of the six Intermediate Whirlwinds.

This magic core was provided by Klein, so he could sense a familiar aura from it.

And this magic core was also very active under Klein's attention. Clearly, it was an affinity that came from the same source.

Therefore, Klein connected the six magic cores. After connecting them, he surrounded the center where Rakshasa was.

The speed of the Intermediate Whirlwind was very fast. Upon receiving Klein's command, they rushed towards Rakshasa.

Wherever they passed, be it the fiery red flames or the elemental explosions that could happen at any time, they would be absorbed or dispersed.

"It seems to be quite useful."

Klein nodded and watched patiently.

He was in no hurry to follow up. After all, the processing of the Intermediate Whirlwind required time.

Furthermore, with so many Intermediate Whirlwinds surrounding him, even Rakshasa would have to spend some effort to break through them, right?

This effort was the time for him to make his move.

At this moment, the spectators below couldn't help but reveal shocked expressions when they saw Klein's Intermediate Whirlwind spell.

Although they were far from being aware of the power of the Intermediate Whirlwind spell, it didn't stop them from seeing the endless stream of Klein's spells.

After all, although they had a magic seed, they didn't have any related magic skills.

Therefore, this thing was no less than a hot potato in their hands.

If it was something else, it would be fine. They could just throw it aside and talk about it later.

However, magic was a mysterious and powerful thing that had already penetrated deep into their souls.

This also originated from the countless excellent magic movies and TV series of the last century, such as the Lord of the Rings 1, 2, 3, Harry Potter, Merlin, and so on.

Therefore, it was under the influence of this idea that their curiosity about magic had practically broken through the sky.

If it weren't for their own magic power being unable to withstand it, they might not have given up on studying magic.

However, although there were some results, the power was very weak, and the good-looking effects were greater than the actual value.

But this was also something that couldn't be helped. After all, how could it be so easy to research magic?

Other than being bold, the most important thing was their understanding of magic, but clearly, none of them had any.

Therefore, when they saw Klein's powerful Intermediate Whirlwind, their eyes widened. If it weren't for the fact that this was the key to fighting the enemy, they wouldn't have been able to help but rub their hands together!

"Holy shit, this spell is so cool!"

"Whirlwind? That's a very realistic name."

"Tsk tsk, I don't know how powerful it is, but it does make me feel a little apprehensive."

"How can it be weak when it's used at a time like this?"

"Indeed. Ignoring everything else, just looking at its color makes my legs go numb. Previously, I saw the afterimage of a tornado on television. Compared to the outside, the tornado inside is pure black. Clearly, this tornado is extremely powerful!"

"How cool! I'm getting tired!"

"Me too. I really want it."

"I wonder if God Klein is taking in a disciple. I don't need anything else. Leave this magic to me!"
