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

Facing the remaining two disguised mushrooms.

With the experience gained from the first real-world battle, Lin You's movements became even more decisive and efficient.

First, use the stone spear to provoke it from a distance, forcing the mushroom monster to reveal itself.

Then, taking advantage of the spear's attack range, he thrust and retreated, fighting steadily and surely.

The two mushroom monsters withered and fell to the ground one after the other before they could even touch the hem of his clothes.

You have defeated 2 "Mushroom Monster"

You have obtained 4 "Mushrooms"

"Six mushrooms now." Lin You picked up her spoils, calculating in her mind.

In this subterranean space, there also grows a large number of colorful mushroom clusters.

Lin You activated his Beginner Eye of Insight, his gaze sweeping over each cluster of mushrooms.

Ordinary mushrooms would appear as faint green outlines in his field of vision.

Mushrooms containing toxins and that are inedible will display a dark red warning light.

After some screening, he found five more common mushrooms that were safe to eat.

You have obtained 5 "Mushrooms"

There are 11 mushrooms in total, enough to eat for a while.

Lin You nodded in satisfaction and returned to the minecart with the mushroom in her arms.

He opened the workbench and looked at the recipe he had obtained earlier.

Simple Campfire: 10 Stones, 5 Wood

[Additional Information: Campfires cannot be crafted inside minecarts; they can only be placed on flat ground. Once placed, they cannot be moved, and maintaining a campfire requires fuel such as wood.]

"It can't be moved..." Lin You pondered for a moment and made a decision.

He glanced at the open space outside the mine cart; the terrain was fairly flat and there were no flammable materials.

"Let's build a campfire here; we need to eat something hot."

He took out stones and wood from the treasure chest and clicked on [Craft].

[With all the materials in place, let's begin...]

[Crafting complete! You have obtained 1 "Simple Campfire".]

[Bonus Information: You have unlocked a new crafting recipe—Charcoal!]

Charcoal: 2 pieces of wood, requires a campfire or furnace

Charcoal can be used as fuel for furnaces and also as fuel for mine carts; each unit of charcoal provides 5 units of fuel.

Lin You's eyes lit up.

"Charcoal can be used to fuel mining carts?!"

This is a major discovery.

He was worried about what to do once the minecart ran out of fuel, as he only had 50 units left.

Now that we have charcoal, the fuel problem is mostly solved.

He immediately set up a simple bonfire in the open space.

A circular hearth surrounded by stones appeared out of nowhere, with a cone-shaped structure made of several pieces of wood in the middle.

Orange-red flames shot up, dispelling a large area of ​​darkness.

A warm feeling washes over you.

The campfire is lit as soon as it is placed, so a fire can be started without any kindling tools.

Lin You skewered the mushrooms with a stone spear and slowly roasted them over a fire.

Soon, golden oil droplets seeped from the surface of the mushrooms, emitting a rich mushroom aroma.

You have obtained 11 "Roasted Mushrooms"

……

Roasted mushrooms

[Level: 1 (White)]

[Effect: Continuously restores stamina and health over 1 minute, up to a maximum of 30 points]

……

"At least we can have something hot to eat."

Lin You picked up a piping hot roasted mushroom and began to chew it with a grimacing expression.

"It tastes very fresh, but it's a pity there are no seasonings."

Lin You licked her lips, still savoring the taste, and put the remaining roasted mushrooms into her backpack.

After a hearty meal, he stared at the crackling firewood in the campfire and suddenly had a new idea.

"While the campfire is still burning, why don't we make some charcoal?"

True to his word, Lin You immediately opened the [Trading Market].

He has run out of timber and needs to replenish it.

As for what to exchange...

No one could resist the aroma of freshly made roasted mushrooms.

[New Item: Roasted Mushrooms x5]

[Pricing: Each serving of roasted mushrooms earns 20 wood]

[Product Description: This product replenishes both stamina and health. Sold individually on a first-come, first-served basis!]

The moment the item was put on the market, the forum exploded.

The chat room was originally filled with discussions of all sorts of miscellaneous topics when suddenly a message flooded the screen.

"Holy crap! Someone's selling food! Grilled mushrooms!"

"Really? Post the link!"

"I saw it! It's that Lin You who posted the strategy guide! He traded roasted mushrooms for wood!"

"20 units of wood for one serving of roasted mushrooms? That's way too expensive!"

"Expensive my foot! I've been digging for so long and haven't even seen a single mushroom!"

"Exactly, even money can't buy food. It's already very kind of Lin You to offer it in exchange."

"Without further ado, I'm switching! I just happened to have some wood saved up!"

"Damn, we got robbed! Who was so fast?!"

In just over ten seconds, the five skewers of grilled mushrooms were devoured by the starving players.

Lin You looked at the notification that the transaction was successful and a slight smile appeared on her lips.

[Transaction successful! You have received 100 "Timber"!]

In the chat room, the group was still engaged in a heated discussion.

"Damn it, I didn't get one..."

"Boss Lin You, do you have any more roasted mushrooms? I'll offer even more!"

"Speaking of which, how did he prepare those roasted mushrooms? You can't eat raw mushrooms, can you?"

"Lin You posted a stone tool recipe before, is he going to post a food recipe this time?"

Seeing people speculating about the content of the next strategy post, Lin You's lips curled up slightly.

He opened the chat room's input panel and slowly typed out a line of text:

"Tomorrow I will post a guide on how to refuel minecarts, and also share the recipes for making campfires and charcoal."

The chat room erupted in excitement as soon as the message was posted.

"How to refuel the mining truck?! Am I seeing things?"

"Great! I've already used up half the fuel, I was just worried about that."

"Lin You is awesome! He can even handle the fuel!"

"Wow, you're a god! Please hurry up and send it, my minecart only has 20 fuel left..."

"It'll be sent tomorrow? Can't it be sent today?"

"Are you stupid? Each person can only post once a day, and the big shot has already posted one today."

"I see... Then let's wait until tomorrow!"

"Hey Lin You, I've added you as a friend, could you accept?"

"I added it too! Check me out, bro!"

However, Lin You had already closed the chat room and continued with her own business.

He took out 40 pieces of wood, put them into the campfire, and burned them in batches.

The remaining 60 units of wood were transferred to a wooden treasure chest on the minecart for later use.

Flames licked the wood, and black charcoal gradually took shape.

The process of burning charcoal is relatively slow and requires some patience.

Lin You happens to be very patient.

A few hours later.

[Firing complete, you have obtained 20 "Charcoal"]

"20 portions of charcoal, each portion adds 5 units of fuel, for a total of 100 units of fuel, which should last for a while."

Lin You carefully put half of the charcoal into the treasure chest.

As for the other half, he placed it in the new facility he had just created.

……

Rock Furnace: The most basic furnace, used for smelting low-level ores.

[Additional Information: You have unlocked the smelting recipes for iron ingots and copper ingots]

[Copper Ingot: 3 Copper Ore, 1 Any Fuel, Time 5 Minutes]

[Iron Ingot: Iron Ore x3, Any Fuel x2, Time Required: 10 minutes]

……

Lin You touched the rough stone surface of the furnace and sighed inwardly.

"This is the real productivity tool."

However, the furnace needs fuel to operate, and since he doesn't have any copper ore at the moment, he's not in a hurry to start smelting.

Next, Lin You drove the mining cart through the surrounding passageways.

They excavated and collected minerals and timber along the way.

I wonder if my luck ran out in the previous digging attempts.

In his subsequent digging attempts, he failed to encounter any other subterranean space.

However, with the discerning eye, he didn't suffer too much of a loss.

They collected a lot of ores and wood along the way.

After an unknown amount of time, the minecart ran out of fuel.

Lin You stopped what she was doing and looked at the time on the game panel.

Current time: 23:59 PM

"Before I knew it, I'd been digging all day..."

Lin You rubbed her sore eyes.

However, the harvest was quite fruitful.

Inventory check:

15 copper ore, 45 stone blocks, 65 dirt blocks

Wood x20, totaling 80 including the wood in the box.

In addition to the mushrooms, charcoal, and other items already in place...

Just then, a system notification sounded.

[Announcement: During the new player protection period, half of the minecart fuel will be automatically restored to all players at midnight every day (rounded up)]

Your minecart fuel has been restored: 50/100

"Turns out it automatically replenishes half the fuel every day!"

Lin You suddenly realized.

This saved him a lot of charcoal.

However, once the newbie protection period ends, you'll still have to find a way to refuel yourself.

He stretched, walked to the campfire, took out a skewer of roasted mushrooms and slowly munched on them, while opening the forum's posting page.

A new day dawned, and he was given another opportunity to post.

After thinking about it, he decided to first write a guide on refueling minecarts.

After all, judging from the reactions in the chat rooms, this is the issue that all players are most concerned about right now.

The post title was quickly drafted:

Say Goodbye to Fuel Anxiety! All Campfire, Charcoal, and Furnace Recipes Revealed!

In the main text, Lin You details the recipe and precautions for making a simple campfire.

How to make charcoal from wood, and the specific proportion of charcoal to supplement the fuel of mining carts.

He also posted the recipe for the rock furnace and mentioned that the furnace can smelt minerals such as copper ingots and iron ingots.

"All of the above recipes have been personally tested and proven effective. I wish you all the best in surviving in the Inner Earth."

Click Publish.

The forum erupted in cheers as soon as the post was published.

"Wow! Lin You has released a new strategy guide!"

"Fuel! Fuel! Finally, we have a way to refuel!"

"A campfire needs wood and stones... I have stones, but where can I get wood?"

"Timber can be bought at the trading market, or you can dig up dead wood from underground."

"One unit of charcoal replenishes 5 units of fuel, so if I replenish 50 units of fuel per day, that's equivalent to 10 units of charcoal. If I use them sparingly, I'll have enough."

"Thanks, sir! My minecart only had 10 fuel left, I almost thought I was going to be trapped underground!"

"Wait, a rock furnace costs 50 stones? I only have 20... Is there a lower-spec version?"

"Be content upstairs, you can't even make a furnace without the recipe."

Lin You munched on a grilled mushroom while browsing the comments.

Seeing the enthusiastic response from the players, he smiled slightly.

The system notification sound blared again.

[Ding! Your strategy post helped other players, earning you +1 strategy point!]

[Ding! You have gained 1 strategy point!]

【Ding! ...]

Watching his strategy points steadily increase, Lin You felt a great sense of satisfaction.

He turned off the system notification sound, found a clean corner in the minecart, and relaxed.

Before long, he drifted off to sleep.

……

"call……"

Lin You woke up feeling refreshed.

Although sleeping on the floor made my body a little stiff.

But overall I managed to get a good night's sleep.

After all, the mine cart is absolutely safe during these few days, so you can rest assured.

"Let me see how many strategy points I've accumulated."

Lin You opened the system interface and glanced at the points.

Strategy Points: 1096

Four digits!

Lin You's eyes widened instantly, and she subconsciously held her breath.

"I've reached one thousand points." Lin You took a deep breath.

He opened his friends list—999+ unread private messages, 999+ friend requests.

The messages were all the same: "Looking for a mentor, please help me out," "Add me as a friend, please," and "I love you, Lin You."

Lin You shook her head and cleared the stranger information with one click.

"Business comes first."

He opened the strategy shop and his eyes fell on the second item.

[S-Rank Job Change Card: 1000 points]

"I bought it."

[Consume 1000 strategy points to obtain "S-Rank Job Change Card" x1.]

A card emitting a dark golden light appeared in Lin You's hand.

The card is engraved with intricate runes, with a question mark in the center.

[S-Rank Job Change Card (Random): After use, you will change to an S-rank job. This job is unique and unlocks the leveling system. Use?]

"use."

Lin You did not hesitate.

A dark golden light burst forth from the card, completely enveloping his body.

A powerful force surged into my limbs and bones.

Countless pieces of information flashed by rapidly in my field of vision.

[Currently changing jobs...]

Congratulations on obtaining the S-rank class – "Card Master"!
