From the moment he arrived in the catacombs world, he had never excavated upwards.

Today would be the first time.

The map indicated that the catacomb above was dangerous and had resources.

If he chose the 17th catacomb above, then the 18th catacomb would be able to dig up an iron treasure chest, and the 19th catacomb would be a silver treasure chest.

A silver treasure chest that was even more advanced than an iron treasure chest!

To be able to obtain a Perfect Runic Crossbow from an iron treasure chest yesterday, the items in the silver treasure chest would definitely be even more impressive.

Jack and Tom would definitely not dare to choose this route.

It was fraught with danger.

But Klein could give it a try.

Especially with the help of Little Fox, he could let Little Fox lure the enemy away first.

Klein looked up at the earthen wall above him.

[There's a dog spider in the catacomb above. If you have a source of fire, you can easily burn the spider silk to avoid being tied up into a mummy and harvest some resources.]

Klein flipped through the illustrated list and searched for the Dog Spider.

Danger Factor: 26.

It was non-toxic, and the spider web was resilient. It was unbreakable with a knife.

Its weakness was that it was afraid of flames, so the spider silk would catch fire easily!

Without the protection of the silk nest, its strength would be greatly reduced.

Klein thought for a moment before saying, "I'll choose to dig upwards. I can Little Fox bring the source of fire up first."

Klein put away the map and first opened the runic base.

He could first climb to the top of the runic base to dig.

The runic base was six meters tall.

The ceiling of the catacomb was about seven meters above the ground.

"I'll dig a tunnel first."

Klein piled up the sand beside the runic base.

He continued to build up.

He used the sand to climb to the roof of the runic base.

Little Fox came up with him

Klein half-squatted and held the shovel with both hands. "I'll start digging in an uncomfortable position."

Digging upwards bit by bit...

Klein had already entered the tunnel, and he walked using the runic base.

Every time he lowered the shovel, the sand would be taken away; the difficulty of digging was greatly reduced.

He dug fifteen meters upwards and dug through.

Klein placed his two feet on both sides of the tunnel and took out half a parchment.

"Little Fox, take the fire source and go up later. Be careful of the big spiders on it. If you see a spider web, light it with fire."

Klein curled up half of the parchment into a roll.

The parchment was a small map that was never used.

"Bite it."

He stuffed one end of the parchment into Little Fox's mouth.

"Mmm mmm mmm..."

Little Fox, who was squatting on Klein's shoulder, obediently held it in her mouth.

Klein took out a flint and a dagger.

He rubbed it lightly.

The sparks lit up the parchment.

It was like lighting a cigarette.

The fox also took a puff and puffed out her cheeks.

"Go up."

Klein gestured.

Little Fox exhaled a puff of white smoke and jumped gently into the black membrane.

Klein used both his hands and feet to reach into the black membrane. With a strong push, his body became lighter than usual. He jumped out of the tunnel.

The seventeenth catacomb!

As far as the eye could see, there were fires everywhere.

With half a parchment in her mouth, the fox ran about, lighting fires.

The web caught fire, like a fuse, and quickly spread.

Spiderwebs crisscrossed the catacomb.

On the wall, with a head of a dog and a spider body, the Dog Spider continuously spit silk, wanting to stop Little Fox.

Little Fox was dexterous, dodging easily, and igniting the webs.

Klein took out the runic crossbow and found a good position to aim at the Dog Spider.

The back of this fellow looked like a dog's head.

It had short brown fur all over its body.

"Switch to multi-shot mode."

Klein pressed his thumb lightly.

[Multi-shot mode activated.]

He pulled the trigger.

Fire!

The Dog Spider focused on dealing with Little Fox. Only when the arrow was almost in front of it did it sense danger.

It jumped to the side.

Pfft!

The bolt pierced through the Dog Spider's fragile body.

Under the multiple-shot mode, the five arrows were concentrated, making it easy to hit.

The Dog Spider slid down the wall.

It only struggled on the ground for a moment before it stopped moving.

[System notification: Soul+1]

"Little Fox, come back," Klein shouted.

There were too many spider webs in the catacomb, and half of the catacomb was on fire.

Little Fox nimbly returned to Klein's side.

Klein brought Little Fox to another side of the catacomb and hid in the runic base.

Although the fire wouldn't burn the two of them to death, the runic base could withstand the high temperature.

Otherwise, the beautiful fur of Little Fox might be charred.

A few minutes later, Klein walked out of the runic base.

The air reeked of roasted meat.

The Dog Spider was already burning.

Klein went over to pick up the Dog Spider's corpse.

[System notification: Roasted Dog Spider Meat+1]

[Roasted Dog Spider Meat: Fragrant Dog Spider meat. It has average nutrition, tastes sour, and is succulent. Current consumption of it has a satiation index of three stars. Overall score: 60.]

It couldn't be further decomposed.

"Succulent..."

Klein thought of the Dog Spider type and felt a chill run down his spine.

If he were to eat it, it would probably explode!

Klein was unwilling to eat it.

"Do you want to eat it?"

He lowered his head to look at the fox.

The fox shook its head repeatedly and took a step back in disgust.

"Alright, I can only hang it up for sale."

Klein opened the trading channel and traded while it was still hot.

'I'll just exchange it for some blueprints.'

His gaze swept across the trading market.

He filtered the blueprints...

Below him were all blueprints.

Some needed to be changed for water, while others needed to be changed for bread and meat.

"This blueprint isn't bad."

"I'm still familiar with it."

Klein smiled.

[Rogers 178.23]

[Item: Exquisite Runic Pot Blueprint]

[Requirement: Any meat (at least 1500g) + 300ml Water]

[Inventory:-1]

[Message from the seller: Bosses, come and pet me!]

The price wasn't cheap.

But it was within Klein's acceptable range.

The Dog Spider in his hands had exceeded 1000g.

Adding a random piece of lizard meat would be just enough.

Water wasn't a problem either. There was a pile.
