Survival in the Core: I'm writing a guide for the entire server.

Lin You crouched down and searched around the corpse of the brutal mushroom monster.

Soon, he noticed something unusual.

Apart from a few ordinary mushrooms.

Beneath the cap of the brutal mushroom monster was a dark yellow mass.

He reached out and peeled away the broken pieces of the fungus flesh, revealing a huge mushroom.

This mushroom is more than three times the size of a regular mushroom!

Moreover, under the torchlight, it even faintly emitted a warm glow.

……

Giant mushroom

Grade: 1 (Blue)

[Note: The king of mushrooms, growing in the most ideal environment, thus developing an extraordinary size]

[Effect: Permanently increases Constitution attribute by 5 points upon direct consumption (only effective once)]

[Additional Information: Consuming this after cooking it in any dish will double its effects and permanently increase your Constitution attribute by 10 points]

……

"Permanently improve physical fitness?!"

Lin You's pupils suddenly dilated, and her breathing became more rapid.

Keep in mind that he only gets 10 free attribute points when he reaches level 2.

The value of this mushroom is equivalent to the attribute growth of a half-level S-rank profession!

"It can double in value if cooked as a dish..."

Lin You licked her lips, forcing herself to calm down.

He now has a cooking pot and can prepare meals anytime.

The problem is, he doesn't know what dishes can be made with giant mushrooms.

Eating it directly by grilling doesn't seem to qualify as "cooking".

"Keep it for now, you'll need it sooner or later."

Lin You put the giant mushroom into her backpack, feeling very happy.

After all, this is just the appetizer.

He then tried to turn the Brutal Mushroom Monster into a Magic Card.

[Card creation failed! You are currently unable to create an Elite Magic Card!]

"Tch, fine."

Lin You curled her lip, thinking to herself that elite monsters were indeed more troublesome than regular enemies.

He stood up and his gaze fell on the bronze treasure chest not far away.

The keyhole of the treasure chest gleamed with a dull metallic sheen in the torchlight.

Lin You took out the copper key he had exchanged for 10 units of coal from his backpack and walked to the treasure chest.

Insert the key into the lock and turn it gently.

"Click".

A crisp mechanical sound rang out, and the treasure chest lid popped open automatically.

Soft light emanated from inside the box, where several items lay quietly on the velvet lining.

Lin You reached out and started flipping through the pages.

You have received 80 "Copper Coins"!

You have obtained 1 "Simple Water Collector Blueprint"!

You have obtained a "Job Change Card: Warrior (Rank E)" x1!

Three items.

Lin You picked up a pile of copper coins and weighed them in her hand.

The heavy coins clinked together, making a crisp sound.

"Although it's not much, at least we're not penniless anymore."

Lin You carefully put away the copper coins and unfolded the blueprint.

……

[Simple Water Collector Drawings]

[Recipe: 10 Copper Ingots, 5 Coal/Charcoal, 5 Slime Gel, Requires a Basic Workbench]

[Additional Information: The water collector can slowly collect purified water, and its efficiency is improved in humid areas.]

……

Lin You's eyes lit up.

drinking water!

This is a survival resource that is just as important as food.

In the long run, a stable water supply is a problem that must be solved.

"The materials needed are all common materials, and we can make it today."

Lin You nodded in satisfaction, put away the blueprints, and planned to study them again when she returned to the minecart.

Finally, there's the job change card.

……

[Job Change Card: Warrior]

Grade: E

[Note: After use, you can change your class to the E-rank "Warrior", unlock the level system, and obtain basic class skills.]

[Additional Information: After changing jobs, each level gained increases Strength and Constitution by 1 point.]

……

Lin You stared at the card, lost in thought.

E-level profession.

Although it's only the lowest-level profession, the value of this card to other players is self-evident.

Having a profession allows you to level up, gain attribute growth, and learn skills.

In this perilous subterranean world, profession and rank often mean the difference between life and death.

"Unfortunately, I don't need it."

Lin You shook her head and put the job change card into her backpack.

He already has the S-rank job "Card Master", so it's impossible for him to change to an E-rank warrior.

In terms of growth potential at each level, the two are worlds apart.

Each level of a Card Master grants 10 attribute points, which can be freely allocated.

The "Warrior" only has a pitiful 2 points of fixed attribute growth.

But you can keep this card.

Whether you sell it at the market or barter it, it should be very popular.

"Let's keep it for now, there's no rush to deal with it."

Lin You stood up and glanced at the empty treasure chest.

Like wooden treasure chests, bronze treasure chests can also be taken away and used as storage containers.

Moreover, the bronze treasure chest has a larger capacity than the wooden treasure chest.

……

[Copper Treasure Chest]

[Capacity: 40 storage slots; similar items can be stacked, with a maximum stacking limit of 50]

[Additional Information: You have obtained the crafting recipe for the "Bronze Treasure Chest"]

[Recipe: 10 Copper Ingots]

……

"40 slots, twice as many as a wooden treasure chest."

Without saying a word, Lin You picked up the bronze treasure chest.

It's quite heavy, weighing at least several dozen kilograms.

But with his current strength of 20 points, this weight is nothing.

Back at the minecart, Lin You placed the bronze treasure chest in the corner of the carriage.

He then began to organize the supplies.

The items in the two wooden treasure chests were all taken out and reorganized according to their categories.

After a flurry of activity, the space inside the mine cart suddenly felt much more spacious.

The freed-up space will naturally be used to install a simple water collection device.

However, we are still short of materials to make a water collector.

Lin You rummaged through the box; he had both copper ingots and charcoal.

However, there were only two portions of slime gel, since he had only encountered slime once.

"I can only buy it from other players."

Lin You opened the trading market and began browsing.

After two days, the market was filled with a dazzling array of goods, all kinds of them.

There are also many types of slime gel.

It seems that quite a few players have killed these low-level monsters.

"The seller's name..."

While browsing, Lin You noticed a seller of slime gel with no hidden name.

……

[For Sale: 10 x Slime Gel]

[Price: 30 copper coins or equivalent value of food and water]

Seller: Vincent (Level 1)

……

Vincent—Lin You remembers—was the one who wrote the post "How to Deal with Slimes".

I even replied with a special message: "May good fortune be with you always."

I never expected to run into it again today.

"The price is reasonable, so I'll buy his."

Lin You didn't haggle; she simply took out 30 copper coins and bought all the gel Vincent had listed.

He then closed the game menu and returned to the minecart.

"We have enough materials... Let's begin!"

[Crafting complete! You have obtained 1 "Simple Water Collector"!]

A crudely designed device appeared on the worktable.

The main body is a copper water tank filled with charcoal powder coated with gel as a filter layer.

After placing the water collector, a message popped up in Lin You's eyes.

[A simple water collector has been placed and is collecting water...]

Collection efficiency: 100 ml of purified water / 1 hour

"One serving of water per hour isn't very efficient, but it's consistent."

Lin You nodded in satisfaction, took out a few roasted mushrooms from her backpack, and swallowed them with the last half bottle of purified water.

Physical strength gradually recovered, but magic power remained completely depleted.

Current Magic Power: 13/200

[Mana Recovery Speed: 2/minute]

At this rate, it will take quite a while to fully recover my mana.

"Alright, let's call it a day."

Lin You yawned and climbed into the mine cart.

"Tick-tock..."

The water collector made a soft dripping sound as drops of clear water fell into the sink.

Lin You closed her eyes and quickly drifted off to sleep.

……

I don't know how much time passed.

Lin You was awakened by a jarring notification sound.

He groggily opened his eyes and turned on the system panel.

Current time: 11:00 AM

[Announcement: The public auction will begin in one hour. Players who wish to participate, please prepare accordingly.]

The auction will open promptly at 12:00 PM, and can be accessed through the game menu at that time.
