The fortieth catacomb.

Klein held the Firestorm Saber and looked around.

Little Fox and Little Wind followed closely behind.

The blade of the Firestorm Saber was one and a half meters long.

It had many complicated patterns.

It was light as a whole, and it didn't take much effort to hold it in his hand.

The speed of the saber was increased, and it could burst into flames. Like a whirlwind, it encircled the saber.

Furthermore, Klein, who possessed the ability of flames, could add more flames to the saber at will.

However, Klein wasn't familiar with it at the moment.

Therefore, he couldn't add too much. He had to keep it within a certain range.

"Roar!"

There was a roar in front of him.

A behemoth pounced at him.

The only underground creature in this catacomb, the Flowing Sand Lion!

It was three meters long and huge. Its entire body was covered in a thick layer of sand armor. Its defensive ability far exceeded that of the Rock Armor Crocodile.

Its danger factor was 34.

It had a fierce and violent temperament, and its ability was to condense sand armor.

It could roll up the sand under its feet and condense into sand armor in the span of a breath.

If it could not break through the defense and kill it in one go, then it could continuously condense sand armor. It was very difficult to deal with.

If he wanted to kill it, he would need a sharp weapon.

Shoo!

Lightning flashed.

It was Klein who shot the Lightning Crossbow.

The arrow pierced through the sand armor of the Flowing Sand Lion.

Roar

The Flowing Sand Lion slowed down its movements, apparently because of the numbing effect.

This arrow failed to kill the Flowing Sand Lion.

Quicksand constantly surged through the wound where the arrow was, condensing into armor once again.

The Flowing Sand Lion pounced at him again.

Klein's movements were nimble as he quickly dodged to the side.

Little Fox and Little Wind were instructed to watch the battle from the side as soon as they entered.

With the enhancement of a Low-Level Agility Enchantment Scroll, Klein's speed increased.

In a flash, he had already circled behind the Flowing Sand Lion.

Klein put away the Lightning Crossbow.

Actually, if he were to use the Lightning Crossbow to kite the Flowing Sand Lion, he would definitely be able to grind the big fellow to death in a few minutes.

However, he had to test the power of the Firestorm Saber.

Klein held the saber with both hands.

With a thought...

A flame ignited on the blade.

In an instant, the entire knife was covered in swirling flames.

The surrounding air suddenly rose!

Klein was the person holding the saber, so he didn't feel it clearly.

Streams of air blew backward from the hilt of the knife, separating the heat from his body.

The air streams gradually turned into white smoke.

Like gray ribbons, they fluttered in the wind.

"Kill."

Klein charged forward.

The Flowing Sand Lion had already reacted. It turned its head and pounced forward.

In the face of the scorching flames, it was instinctively afraid, and the sand armor on its body was even thicker.

As long as it could withstand one strike, it would definitely be able to destroy the intruder!

The Flowing Sand Lion was confident in its sand armor.

Pfft!

One strike.

It was like cutting tofu.

The Firestorm Saber easily sliced through the sand armor.

One of the Flowing Sand Lion's forelimbs landed on the ground,

Another strike...

Following closely behind, it was as though the first strike had just landed when the second strike followed.

The Flowing Sand Lion was split into two!

Its internal organs and blood flowed all over the ground.

The quicksand that covered its body disintegrated.

Klein sheathed his saber.

He looked at the Flowing Sand Lion on the ground.

The wounds were either charred or melted.

The sand armor from before seemed to be nonexistent.

"Is this the Rare Firestorm Saber?"

Klein revealed a satisfied smile.

The high temperature could rapidly melt armor.

The Flowing Sand Lion's body was tough, but it couldn't withstand a single strike.

[System notification: Flowing Sand Lion Meat+12]

[System notification: Flowing Sand Lion Blood+1,000 ml ]

[System notification: Flowing Sand Lion Bone+6]

[System notification: Flowing Sand Lion Skin+1]

Klein decomposed the corpse.

There was more blood and meat to begin with.

A portion of the blood was burned dry.

A portion of the meat was charred!

The Flowing Sand Lion blood didn't have any special effects.

There was meat.

[Flowing Sand Lion Meat: It tastes average and is often consumed. A weapon forged with earth runes will increase your affinity with it. Current satiation index is three stars. Overall score is 68...]

"If it's wind runes or fire runes, it would be better."

Klein touched his wrist and said, "However, the affinity earth runes aren't bad either. The strength bracers use earth runes."

It was better than having no effect.

Unfortunately, the meat didn't taste good.

Klein came to a corner.

There was an iron treasure chest in the catacomb.

After checking it, he opened it!

[System notification: Iron Treasure Chest+1]

[System notification: 300ml Cola+4]

[System notification: Fire Runes+2]

[System notification: Earth Runes+1]

[System notification: Chili Seeds+4]

[System notification: Perfect Leap Combat Boots Blueprint+1]

Klein raised his eyebrows.

Another runic equipment!

He learned decisively.

[Perfect Leap Combat Boots: Wind Runes 1/2, Earth Runes 8/2, Iron 95/8, Copper 87/5, Beast Bones 36/6, Beast Skin 9/12]

[Details: Wear it and feel like you're flying. Maybe you don't have an advantage in terms of speed, but you can jump up to a few meters.]

"Hey, it's not acceleration."

Klein shook his head, feeling a little disappointed.

At the moment, he had a floating propeller.

He could jump as high as he wanted.

The ability to transform into a flying combat boots was a little redundant.

"It's better than nothing. I got more from opening the box this time, mainly Coke and chili seeds."

Klein stuck out his tongue and licked his lips.

Naturally, he didn't need too much Cola.

There were four bottles in total, and he could enjoy them for a few days.

Chili was one of Klein's favorite condiments.

In the past, he didn't like anything that wasn't spicy.

Although he had switched to chili noodles, he still missed the taste of ordinary chili.

Even if it was just condiments and not necessities of life, it was worth it for him to make a planter that was specially used to cultivate chili peppers!

Klein thought for a moment before saying, "There are still quite a number of resources on the ground. Let's search them thoroughly first."

Klein noticed that there were more than ten balls of plants not far away.

If he wasn't wrong, they should be one of the ingredients for the antidote: the Ball Rolling Grass!

If the antidote was produced by Klein, it would probably be in high demand if it was put on the market.

Many of the crypt creatures were poisonous.

Or if they accidentally entered the poison chamber, they would need it.
