The more Rogue Archer thought about it, the more right he was. The more he thought about it, the angrier he got.

He finally realized what he had done wrong.

He had given the enemy a lot of time to research.

He never expected that the other party had actually found a way to succeed!

If this continued, once the other party succeeded in his research, wouldn't he have no chance of turning the tables?

With this thought in mind, cold sweat broke out on the Rogue Archer's face.

'Darn it, I can't let him continue his research,' the Rogue Archer thought to himself as he stealthily made his way towards Klein.

Although the Rogue Archer was furious, he knew that Klein was very strong.

He only had one chance to attack. Once he was caught by the other party, it was very likely that he would die in the next second.

Therefore, it was extremely careful. It moved its feet gently on the ground, not daring to make a sound.

Compared to Klein, it still had an advantage.

It was that the enemy hadn't succeeded yet.

Although it was already on the verge of success, it was still one step away from success.

This was the enemy's chance, and it was also its chance.

As a qualified hunter, it knew where the enemy was most relaxed.

And what it needed to do now was to wait patiently.

And a spot where the enemy would definitely die!

The Rogue Archer wasn't fast, but thankfully, it had plenty of time.

And at that moment, the smile on Klein's face grew even wider.

He knew that he had found a way forward.

Furthermore, the tornado this time was about to reach its limit.

As long as he crossed it, he would be able to increase the power of the tornado by ten times. Furthermore, it would have a sharp characteristic.

When the tornado was increased by ten times, with the support of the Endless Sword, it would erupt with wind power that could be considered a natural disaster. At that time, not to mention a tiny Rogue Archer, even the Stone of Destruction would be destroyed by Klein's tornado.

Klein sensed the tornado in his hand and constantly adjusted the ratio, limiting its speed in sensing the surrounding wind elements.

Suddenly, his speed was too fast, causing the tornado that was about to take form to instantly dissipate.

However, Klein wasn't displeased at all. Instead, he revealed an extremely excited expression.

That's right, a smile had already appeared on Klein's face.

He could clearly sense the failure of the last adjustment. It had indeed allowed the tornado's might to reach its maximum!

Although it failed, it confirmed his guess!

With this in mind, Klein couldn't wait to try it out.

Soon, a grayish-black tornado took shape in Klein's hand.

There were also traces of golden swirls at the edges.

The tornado spun very quickly, but it didn't scatter, as if everything was set in stone.

Feeling the tornado in his hand, Klein swallowed his saliva. He knew that the final match had succeeded. Now, it was time to test it.

To be honest, Klein was a little excited.

This was the first time he had developed such a huge spell.

Its immense power even exceeded the Golden Spiral Shuriken in his hand.

Once it was cast, his guess was that the world would change color and its power would be terrifying. It would definitely become a huge killing move for him!

With this in mind, Klein didn't hesitate any longer. He gently tossed the tornado in his hand.

The tornado flew out of Klein's hand.

The tornado that flew out was different from before.

The previous tornadoes had landed at the first moment, rapidly accumulating their size to speed up their growth.

But the grayish-black tornado was different. It flew straight into the air at a very fast speed. In just a few seconds, it had reached a height of a hundred meters!

The sudden change in front of him stunned Klein.

This was the first time the tornado had changed in such a way.

Although it could fly before, it wasn't that high.

Furthermore, it quickly landed after flying.

But this time, Klein had a faint feeling that he was heading in the right direction.

As expected, the tornado that flew into the sky finally reached its limit. As though it had been detonated, it instantly exploded in the air.

The tornado that exploded did not disappear, but increased rapidly.

That's right, the wind elements between heaven and earth were completely stirred up by this explosion.

Soon, a small grayish-black tornado appeared in the sky where the tornado had exploded.

It was like a small boat in the ocean and a candle in the endless darkness.

But this point was like a spark that ignited a prairie fire, instantly igniting the endless grass and trees.

The entire space shook.

In a short few seconds, a huge tornado appeared where the grayish-black tornado was in the sky.

Not only that, the tornado's speed was very fast. In an instant, it crashed from dozens of meters high into the ground, instantly creating a seven to eight meter deep pit.

The tornado also borrowed this strength to become bigger and bigger.

Looking up from the bottom, the tornado seemed to have become a skyscraper. The only difference was that this skyscraper was evolving rapidly.

At this time, the world was still changing colors.

The first thing that changed was the earth.

Everything within the tornado's range, broken branches, wasteland, and large rocks, were instantly stirred up into the endless sky. As it rose higher and higher, under the friction of the rotation, it was finally completely stirred up, turning into gravel and dust.

And in the sky, a cloud appeared.

No!

It was a cloud, a pitch-black cloud.

After it appeared, it completely covered the location of the tornado.

At that moment, the place where the tornado was was dark black, as though the end of the world had arrived.

'I've finally succeeded.'

Klein looked at the tornado in the sky. He knew that his experiment had succeeded!

Although the speed at which the tornado was born was very slow, its power greatly exceeded Klein's expectations.

He guessed that the tornado's power was at least level 17.

The center of the tornado was spinning at a speed of 120 meters per second!

Just as Klein was admiring his masterpiece, there was the sound of air being torn apart.

The Rogue Archer finally made a move.

He looked at the tornado in the sky, his face completely pale.

It was true that he was a crypt creature, but he wasn't stupid. How could he not know that the human in front of him had succeeded in the end? He had actually developed such a huge tornado.

God knows how a human, an ordinary human, could be so powerful!

He didn't know. The only thing he knew was that he had no chance.

Or perhaps, this was the last chance.

If he couldn't kill Klein or seriously injure him, he would definitely be killed by the terrifying tornado in the sky.

Therefore, he couldn't hold it in any longer and decisively attacked ten meters away from Klein.

The sound wasn't loud. Under the tornado's sweep, the sound was similar to that of a mosquito.

To an archer, a distance of ten meters was just an instant.

At that moment, the Rogue Archer's eyes had already seen Klein's tragic end!
