Bam!

The elemental missile instantly smashed towards the Cactus Monster King.

White smoke immediately rose from the body of the Cactus Monster King.

The white smoke quickly dissipated.

However, Klein, who was careful, still noticed that there was a black spot where he had just attacked.

There was a black spot!

'Could it be that this fellow's weakness is water?'

Based on the knowledge he obtained in the previous world, Klein thought that the weakness of cacti was water!

Cacti were different from ordinary plants. They didn't need water and only needed sunlight.

If he watered the cactus, it would quickly wither and die.

Therefore, Klein had tentatively used a water elemental missile on the Cactus Monster King.

He didn't expect it to really work!

The Cactus Monster King let out a tragic cry.

Its eyes revealed a hint of shock.

Immediately following that, it was filled with anger.

The human in front of it had actually hurt it!

This was something it absolutely couldn't tolerate.

After so many years, no creature that had set foot in this realm had ever hurt it.

No!

After all, an existence that could harm it had to know how to use water!

And when they entered this catacomb, the water would definitely evaporate.

Therefore, even if it was a creature that used water, it was absolutely impossible for it to use water to attack it after coming to this catacomb.

This was absolutely impossible!

However, what was going on with this human in front of him?

The Cactus Monster King felt a burning sensation in the area above his eyes.

It was very painful.

The Cactus Monster King was enraged and suddenly used an accelerated fist technique on Klein!

These fists were very fast, like machine guns.

On the ground, wherever the fists hit, large craters appeared.

Klein could only use the flames released by the Golden Firestorm Saber to collide with the Cactus Monster King's fist, causing the thick smoke to act as an obstacle before flying into the air.

He continued to use water elemental missiles against the Cactus Monster King.

This time, he fired ten consecutive shots!

After Klein confirmed that the water elemental missiles had a very strong lethality against the Cactus Monster King.

He simply released them all at once.

He fired the most consecutive shots in the shortest amount of time possible.

The ten water elemental missiles directly hit the Cactus Monster King.

The Cactus Monster King howled in pain.

It instantly lost its imposing manner from before.

Seeing this, Klein continued firing the water elemental missiles.

Klein was currently very energetic. No matter how many water elemental missiles he fired, there wouldn't be any problems.

These elemental missiles directly forced the Cactus Monster King to retreat.

The expression on its face became extremely distorted.

"Wuwuwu!"

The Cactus Monster King was enraged.

It began to spin rapidly, producing a large number of flying spikes as it attacked Klein.

Klein took the opportunity to use the flames released by the Golden Firestorm Saber to help him block.

As he blocked, Klein's other hand continued to release water elemental missiles at the Cactus Monster King.

The Cactus Monster King was forced to stop spinning in pain and began to retreat.

"You want to run?"

Klein's gaze focused as he hurriedly chased after the Cactus Monster King and continuously attacked it.

The water elemental missiles struck the Cactus Monster King in all sorts of brainless ways.

The Cactus Monster King was in excruciating pain.

Large areas of its body turned black.

They were all wounds caused by the water elemental missiles.

Finally, under Klein's series of fierce attacks, the Cactus Monster King fell to the ground.

It was dead.

Klein immediately dissected the Cactus Monster King's corpse.

[Cactus Dew+1]

[Cactus Thorn+100]

[Fire Rune+50]

...

[Cactus Dew: It can increase water elemental attributes for any non-living substance.]

[Cactus Thorn: It can be used when eating barbecue. It can increase the taste of the barbecue by 10%! Furthermore, it can be used permanently and won't carbonize!]

'Perhaps, I can try putting these two items on the shelves in the mall?'

Klein thought to himself.

Furthermore, the Stone Armor Ironstone from before could be sold to those who needed them.

These are all very good items.

With this in mind, Klein instantly put these goods on the shelves in the mall.

After finishing the processing, Klein immediately took out the cactus dew.

He had already thought of how to use it.

Golden Firestorm Saber!

Using the cactus dew on the Golden Firestorm Saber could increase its water element attribute.

In this way, Klein could attach the water element to the Golden Firestorm Saber.

The Golden Firestorm Saber could use both water and fire elements at the same time!

The power would definitely increase by a lot compared to before.

Klein instantly put this idea into action.

When the cactus dew was smeared on the body of the Golden Firestorm Saber, the Golden Firestorm Saber instantly flashed with a few blue lights.

"The water element attribute has been successfully added!"

Klein was delighted.

He picked up the Golden Firestorm Saber and waved it in his hand.

It felt softer than before.

He wouldn't feel tired if he held it tightly.

Klein believed that this was because the softness attribute of water had improved the feel of the Golden Firestorm Saber.

In the long-term battles to come, Klein wouldn't be affected by the feeling of the Golden Firestorm Saber.

A ripple appeared on the body of the Golden Firestorm Saber.

The ripple formed the shape of a sharp blade.

Water blade!

Klein waved his hand casually.

The water blade instantly created a crack on the ground.

It was extremely sharp.

Klein tried it a few more times.

It felt really nice to the touch.

And it was very powerful.

Compared to the flames from before, it was faster.

And it was very quiet.

The damage it caused wouldn't attract anyone's attention.

It was suitable for assassination!

Klein retrieved his Golden Firestorm Saber with satisfaction.

He wanted to use it the next time he faced a creature from the catacombs world.

Klein opened the trading mall.

Suddenly, he realized that his private messages had been flooded with messages.

A group of people wanted to buy the two items that Klein had put on the shelves.

"Big Boss Klein, can this Stone Armor Ironstone really be used to forge an extremely sharp weapon? I want it!"

"Big Boss Klein, I want this cactus spike. It'll be great to eat it on a kebab! I especially love barbecuing. Please save one for me!"

"Big Brother Klein is awesome. I want both!"
