Try Flying!

Both required wind runes.

At the moment, he could only forge one.

Klein thought for a moment before saying, "I have a runic crossbow now. As long as I don't encounter any fast-moving crypt creatures, I don't need to engage in close combat."

"Compared to my full-range melee abilities, at the current stage, long-range attacks are more suitable for me."

"At the very least, it can guarantee that I won't be easily injured."

Klein thought about it and decided to first create the floating propeller.

He would wait until he was more proficient with his knife skills or had gathered enough materials before creating the runic speed blade.

[Perfect Floating Propeller: Wind Rune 2/2, Copper 42/12, Iron 45/12, Silver 4/2]

Confirm creation!

[System notification: Wind Rune-2, Copper-12, Iron-12, Silver-2]

[System notification: The Perfect Floating Propeller has been successfully forged.]

Klein's hand sank.

A backpack-like instrument appeared in his hand.

As usual, there were many complicated patterns on the surface.

The main materials were copper and iron.

This meant that the internal parts were silver.

The entire instrument was not as bloated as expected. It was less than a foot in length horizontally, half a foot in length lengthwise, and three inches in thickness.

There were two jet tubes on the right.

[System notification: Additional soul required.]

Klein pursed his lips.

As expected, he needed another soul as an energy source.

After adding one soul, he checked the details of the item again.

[Perfect Floating Propeller: 30/30 minutes]

One soul could fly for 30 minutes.

"I wonder what the flying effect will be?"

Klein flipped his hand and placed the floating propeller on the waist of his back.

Crunch!

The floating propeller had four ring-shaped grappling hooks, one on the left and one on the right, firmly grasping his waist.

The two jet pipes on his back immediately spewed out powerful winds.

"Let's levitate."

Klein's feet left the ground as he slowly flew up into the sky.

This thing was a little good. He could control it with his mind.

Buzz! Buzz! Buzz!

The Little Fox, who was originally bored and playing with fire, was very curious when she saw Klein fly up into the sky, descend, and run laps below.

'I'll try my speed,'  Klein thought again.

Phew!

The force of the wind increased.

He transformed into a shadow and flew out.

Down, front, back, left, right.

His speed wasn't slow at all.

Furthermore, he could turn nimbly in the air.

Klein tried for two minutes and gradually grasped the control method, becoming more and more adept at it.

He was even more agile than he was on the ground!

On the ground, he could only move forward, backward, left, and right. He could move up and down in the air, and his speed was faster than his running speed.

"Wu, wu, wu!"

The fox chased after him on the ground as though it was saying, "Master, take me flying!"

Klein laughed and landed. He picked up the fox and continued flying.

After flying for a total of five minutes, Klein was already familiar with the operation.

"I'm not playing anymore. There are still many resources on the ground waiting for me to gather."

Klein smiled as he landed and put away the floating propeller.

In this catacomb, not only were there silver treasure chests, there were also a lot of resources.

[Wood+20, Stone+15, Iron+18, Copper+12, Black Vine+4, Black Vine Fruit+2...]

He looted everything.

'There are still six excavations left today. Let's take a break first.'

Klein needed to observe the hints in five directions first, then go to the market to sell some goods.

He was gonna charge top dollar for a bunch of runes.

The upgrade scrolls needed to runes as well as the runic speed blade, and the pot also needed it.

[There's fresh air in the caves above.]

[The catacombs below are extremely dangerous, full of booby traps and meager supplies.]

[Keep digging. The ground is full of lava, but there are three treasure chests high up.]

[Dig to the left. There's a One-Eyed Lizard and some resources there.]

[Dig to the right. A nest of poisonous insects is waiting for you. You can try turning into a pig's head.]

Klein took a glance at the cave ahead.

With the floating propeller, he could easily avoid the lava on the ground.

However, the next cave would only have four directions to choose from.

Klein temporarily didn't have the ability to dig into the magma.

If the four directions of the next catacombs were extremely dangerous...

'I shouldn't be so unlucky. There's no need to be so cautious.'

Klein patted his cheek and muttered, "I don't want to think too much. I'll go put it up and sell it first."

He opened the trade channel.

Goods on sale.

[Seller: Klein 182.56]

[Products on sale: 2 One-Eyed Lizard Meat]

[Requirements: Any Runes]

[Inventory: 2]

[Products on sale: 2 Yellow Sand Octopus Meat]

[Requirements: Any Rune]

[Inventory: 4]

[Products on sale: 800g Wheat Bread]

[Requirements: Any Runes]

[Inventory: 1]

[Products on sale: 600ml water]

[Requirements: Any Runes]

[Inventory: 3]

Klein listed four items in a row.

Among them, wheat bread was obtained from Jack and Tom.

The meat of the One-Eyed Lizard and Yellow Sand Octopus only had some nutrients and could only be used.  It didn't have any extra effects.

It was worse than a meat farm.

Therefore, it was also emptied out.

If this meat was kept for too long, it would gradually rot.

In contrast, the Rock Armor Crocodile meat had a special effect. Even if it wasn't fresh, it had to be eaten.

The reason why the water was only 1,800 ml was because there wasn't much stock.

Although he had prepared another 3,500 ml today, the overall consumption was high.

After drinking, stewing, watering the meat field, and so on, there was only 2,100 ml left.

'I wonder how much I can sell it for? My price is definitely one of a kind on the market. How many people are willing to exchange runes with me?'

Klein closed the interface, picked up the shovel, and dug the tunnel in the dark.

The rune transaction would definitely not be completed in a short period of time, so he didn't need to pay attention to it for the time being.
