After carefully feeling the Power of the Wind, Klein couldn’t help but nod.

As expected, orthodox magic was better than self-developed magic!

Not only that, even the consumption rate of magic had been reduced by several times compared to before.

With Klein’s current magic reserves, as long as he didn’t take the initiative to cancel the spell that contained the Power of the Wind, he could almost activate the Power of the Wind for a long period of time.

However, there was no need to.

It was too flashy.

Just think about it. Wouldn’t it be too sudden for a person to be carrying a lightsaber that was taller than a person?

He still had to keep a low profile!

Following that, Klein took out the other magic book.

Magic Book, Vacuum Strike

Tier 7 Spell

Cooldown: 3 seconds, instant cast

Skill Details: After casting, the weapon will shoot out a wind slash. The wind slash has a sharp characteristic.

Sharp Characteristic: Possesses 20% true damage and carries a Serious Injury Effect (Serious Injury: inhibits the speed of the enemy’s wound regeneration, at most 50%).

Looking at the system’s introduction, Klein’s eyes lit up.

He didn’t expect this spell to be so powerful.

It was the same spell as his saber flash.

But it was faster than the speed of the saber flash.

One in three seconds meant that he had a powerful instant-cast skill.

Once he encountered an area-of-effect attack, he wouldn’t need to rely on Whirlwind.

Most importantly, this also had a true damage effect.

Klein knew the true damage attribute. It ignored magic shields and physical shields.

Once it hit, it meant that the enemy wasn’t wearing armor.

If the Vacuum Strike dealt 100 damage, then 20% true damage could deal 20 true damage.

But clearly, a tier 7 spell couldn’t only deal such damage.

With this Vacuum Strike, Klein had the ability to deal with the Bloody Figure.

If he had this skill before, even if the Blood Lake could devour Klein’s attacks, he still wouldn’t be able to escape the true damage.

This was the overbearingness of true damage.

Regardless of whether it was a physical shield, a magic shield, or any form of counteracting damage, it couldn’t eliminate the true damage. Once it hit, it would be hit.

Following that, Klein looked at the third attribute of the Vacuum Strike — Serious Injury.

Serious Injury could weaken the enemy’s recovery ability.

Previously, when the Endless Sword slashed at the Bloody Figure’s neck, due to the magical elements attached to the Endless Sword, the Bloody Figure had no way of recovering from the cut.

And the critical injury attribute was similar to this attribute.

But it was even more domineering.

Once used, even if one drew their weapon, it would be difficult for the enemy to recover from the cut in a short period of time.

This was simply a god-tier melee weapon.

One had to know that many bosses now had extremely strong recovery abilities. Sometimes, the injuries that you had just caused could be healed in the next second.

But with this passivity, it perfectly countered these blood bulls.

Following that, Klein clicked to learn.

A huge amount of knowledge was transferred into Klein’s mind.

After obtaining this knowledge, Klein once again improved his understanding of magic.

But as he learned more about magic, he also felt that the magic from before was crude.

For example, it was all strikes and the blade light of the Endless Sword. It was more like the pure magic energy that Klein had used to slash out. The five types of energy mixed together, creating a huge mess for the enemy.

Although it looked very strong, it was useless against a true expert.

Most importantly, the mixed elements inside caused the blade ray to fly very slowly, and it was very easy to cause an elemental explosion.

When he thought of this, Klein couldn’t help but wipe the cold sweat off his head.

This was because the elemental power mixed in the blade ray was too complex.

There were his five elements, as well as the five elements between heaven and earth. When these elements were mixed together, it was very easy for them to come into contact, resulting in a terrifying elemental explosion.

In other words, when he began to condense the saber ray, the danger of an elemental explosion had already appeared.

Fortunately, he was lucky that there hadn’t been an explosion before. Otherwise, with the power of the elemental explosion, Klein might not have been able to withstand it at all!

And that wasn’t the only downside.

The casting of the saber flash consumed a lot of magic. Every time he cast it, Klein could only cast more than ten spells.

But even now, with Klein’s massive storage capacity, he could only double the number of spells he could cast.

Why?

Of course, it was because the consumption of the saber flash increased exponentially.

Casting too much in a short period of time would deplete a large amount of magic reserves.

But the Vacuum Strike was completely different!

It mainly absorbed one-third of Klein’s spells and then absorbed the free wind elements in the air while flying to increase the other two-thirds of the spells.

Of course, Klein could also use his full strength to increase the power of the Vacuum Strike to the maximum.

This would consume more magic, but it was still much less than the amount of light from the saber.

“What a good item!”

Klein nodded in satisfaction.

With this skill, would it be so difficult for him to fight the bosses?

Following that, Klein picked up the endless blade and cast a Vacuum Strike.

Instantly, the Vacuum Strike whistled out.

The terrifying speed stunned Klein.

This speed was actually faster than the speed of the Golden Spiral Shuriken.

It was as though it had only been an instant from the attack to the hit.

One had to know that the saber flash from before was a level slower than the Whirlwind.

You want to hit the enemy?

Dream on!

Unless Klein used the Whirlwind to control the enemy first, just like when he faced the Undying Dead.

Klein had used the Whirlwind spell to control the Undying Dead’s other hand.

If it wasn’t for the final Traitor Zekos, the Undying Dead would probably have been tortured to death by Klein.

But if he didn’t use the Whirlwind spell first, Klein would probably be dreaming if he wanted to hit the Undying Dead with the saber beam!

But it was different now.

The Vacuum Strike was extremely powerful and fast.

Clearly, Klein could abandon the saber beam.

The Vacuum Strike that flew out instantly split the mountain, which was dozens of meters tall, in half from the middle.

What made Klein most incredulous was…

The growth attribute of the Vacuum Strike.

He originally thought that there was a limit to the growth.

But he didn’t expect that the Vacuum Strike that was sent out would grow from its original height of two meters to four meters in mid-flight, increasing it by two times.

And that was only the short flight distance. If it was further away, with the growth speed of the Vacuum Strike, it could at least double.

‘Not bad, not bad! I finally have a skill!’

Klein was very satisfied with the power of the Vacuum Strike.

He struck his surroundings a few more times.

The power was still as Klein had expected. It was so powerful.

Even the two spirit beasts couldn’t help but feel chills down their spines when they saw this scene.

This was because the reality of the Vacuum Strike was very powerful against the enemy.
