[Excellent Water Condenser: It's a daily runic device. It can be activated by adding fuel. It can not be activated in the state of combat.]

Klein's palm touched the water condenser.

It wasn't big, but its design was rather exquisite.

It had a lid and looked like a small pill furnace.

The interior should be a water condenser.

The storage state meant that it could be activated by placing it in the runic base.

[System notification: Adding 4 wood can put it into operation for 1 hour.]

[System notification: Adding 1 soul can put it into operation for 8 hours.]

Klein was taken aback.

A soul could be used as fuel?

In addition, how much water would be left after one hour of operation?

Klein didn't plan on consuming this soul.

After all, it wasn't easy to obtain this thing from the crypt creatures.

Obtaining wood was relatively easy.

"Let's first plunder the resources in the catacombs."

Klein put the items away and looked elsewhere.

There were some stones on the ground.

He squatted down to pick them up.

[System notification: Stone+1]

[System notification: Stone+1]

[System notification: Stone+1]

..

Stone+8!

In addition, he dug out a large piece of wood and gained 2 units of wood.

Klein opened the crafting interface.

He locked onto one of the tools.

[Ordinary Construction Hammer: Wood 6/2, Stone 8/2]

He selected this item.

He confirmed the crafting.

Klein had wanted to craft this tool early in the morning.

However, he was always short of stones.

[System notification: Wood-2. Stone-2]

[System notification: Ordinary Construction Hammer successfully crafted ]

A simple-looking, large stone hammer appeared in Klein's hand.

It had a wooden handle.

The hammer's head was made of two fist-sized stones.

[Ordinary Construction Hammer: It can be used to construct and repair buildings. Your runic base needs it.]

Klein opened the runic base without tying his belt.

When he faced the runic base again, two options popped up on the interface.

[Repair]

[Construction]

Among them, the repair button was bright, and the construction button was gray.

The repair wasn't complete, and construction of the runic base wasn't allowed.

Klein tapped on the repair function.

[Repair Progress: 0/6]

[Repair Materials: Soul 1/1, Stone 6/5, Copper 4/2, Iron 1/2, Fire Rune 1/1, Wind Rune 0/1]

A total of six materials were required.

Currently, he was lacking a wind rune and a piece of iron.

"It seems like I can repair them separately."

Klein first added a stone.

The repair began. Stone-5.

He raised his construction hammer and gave it a symbolic knock twice.

The slightly damaged runic base was flattened in an instant.

At this moment, when he checked the progress of the repair, it was already 1/6.

"It looks better than before."

Klein put away the runic base and opened the trade channel.

No one had traded with the water that was put up yesterday.

Klein already had fire runes.

Therefore, he changed the trade request to wind runes.

"Let's continue to the next catacomb."

Klein began to check the catacombs in five directions.

From the fifth to the sixth catacomb, every choice had risks.

And from the sixth to the seventh catacomb, Klein inspected them. Every catacomb had rewards, and there was no danger.

[There's a bronze treasure chest in the back catacomb. There seems to be quite a number of items.]

After some consideration, Klein chose to dig the tunnel behind.

Huff! Huff! Huff! Huff! Huff!

He buried his head and continued digging.

He arrived at the seventh catacomb.

Klein immediately came in front of the bronze treasure chest.

The golden prompt was non-toxic and harmless.

Open the bronze treasure chest!

[System notification: Bronze Treasure Chest+1]

[System notification: Bronze Treasure Chest can be broken down into 4 copper pieces. Do you wish to break it down?]

[System notification: Flint+1]

[System notification: Bacon+4]

[System notification: Ordinary Healing Medicine Forging Blueprint+1]

[System notification: Do you wish to learn Ordinary Healing Medicine Forging Blueprint?]

Several notifications popped up in succession.

Klein first broke down the copper treasure chest and learned the recipe for healing medicine.

A light flashed...

[System notification: Successful learning]

Klein opened the recipe list and found the recipe for healing medicine that he had just learned at the bottom.

[Ordinary Healing Medicine: Fluorescent Grass 6/2, Black Vine 0/2, Cold Play Grass 0/3, Red Flower 0/3, Water 760/200ml ]

There were only two materials he had.

Klein took a glance and opened the trading channel.

Searching for Black Vine...

Some people had collected it and put it up.

While searching for Cold Play Grass and Red Flower, there were also people putting it up for sale.

"These are not rare items."

"The seller only wants water and food."

"Also, no one is selling healing medicine for the time being."

Klein ran to the chat channel again and searched for keywords such as 'injured' and 'bleeding'.

Quite a number of results popped up.

In less than two days, the catacombs had already produced many injured people.

If he could produce healing medicine and throw it into the market, there would definitely be people who would want it.

Of course, in the short term, water and food would definitely be the most sought after.

After some time, when everyone steadied their footing, the healing medicine would show its value.

[System notification: 400 ml mineral water completed transaction, Wind Rune+1]

As Klein pondered, the mineral water that he had put up for the entire night was finally sold.

With that, all he needed to do was collect another piece of iron, and he would be able to completely restore the runic base!

Klein only had less than a bottle of mineral water left, but he had exchanged it for a wind rune.

A rune that symbolized the wind was engraved on the surface, and its surface emitted a green fluorescence.

It felt as though a gentle breeze was blowing in his hand.

Klein fiddled with the rune for a moment before putting it away.

"Continue digging!"

He picked up the shovel and checked the caves in five directions at once.
