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

Over the past few days, the forum in the newbie zone (No. 25535) has become completely different from what it was three days ago.

It was no longer a scene of wailing and pleas for help, but rather filled with valuable intelligence sharing.

Lin You scrolled through the posting section, nodding occasionally.

"Classification and Coping Strategies of Earth's Core Environment" - This is good.

He clicked on it and read it carefully.

The poster was a player named "Elena".

The post is rich in pictures and text, providing a detailed summary of the various environmental types in the Earth's core.

[Normal Digging Area: The most common underground space, with evenly distributed resources and low-strength monsters, suitable for beginners to explore]

[Rock Zone: Hard rock formations double fuel consumption, but mineral production also doubles, making it suitable for resource gathering]

[Underground Jungle Area: Dense vegetation and abundant wood resources, but there are many mushroom monsters, so torches are needed for lighting]

[Spore Zone: Poisonous spores float in the air. You need to wear a mask or continuously purify your environment to enter. There is a chance to obtain rare herbs.]

[Underground River Area: There is a flowing groundwater source, which can collect and purify large quantities of water, but there are piranhas in the river, so caution is advised.]

……

Lin You watched with great interest.

He experienced these environmental types, including rocky areas and ordinary excavation areas.

However, we have not yet encountered the underground jungle area, spore area, or underground river area.

"It seems the environment of the inner Earth is much more diverse than I imagined."

He continued scrolling down.

At the end of the post, Elena also added a note:

"The above environmental types are a summary of my and a few friends' explorations over the past few days, and I hope they will be helpful to everyone."

"If there are any omissions or errors, please feel free to add or correct them."

"Special thanks to Lin You for the guide. Without your guidance, we might not even have been able to create the basic tools."

"Lin You, if you see this post, I hope we can add each other as friends. I have some discoveries about the Spore Zone that I'd like to discuss with you."

Lin You smiled slightly after reading it.

"This Elena is quite thoughtful."

He clicked on Elena's profile picture and sent her a friend request.

Postscript: "Thanks for sharing, let's chat sometime."

Then he continued browsing the forum.

In the posting section, there are also many other high-quality posts from other players.

Ten Uses of Slime Gel; A Quick Guide to Collecting Subterranean Wood

"Analysis of Price Trends in Trading Markets," "Tips for Dealing with the Undead Plague," etc.

Lin You read them one by one, extracting information that was useful to her.

"On the fifth day of the survival game, the quality of the forum has completely changed."

He was deeply moved.

Five days ago, this place was filled with "Help!", "Is anyone there?", and "I'm scared".

Now, some people have begun to systematically analyze the game mechanics and share their exploration experiences.

"That's the human ability to learn and adapt."

Lin You opened the trading market, preparing to purchase the materials needed to make the Spirit Summoning Lantern.

The business of selling brass keys remains booming.

The batch of bronze keys he had previously put up had all sold out, earning him 15 silver coins.

Adding the remaining 4 silver coins and 55 copper coins.

He now has a total of 19 silver coins and 55 copper coins in working capital.

"We have sufficient funds and can make large-scale purchases."

Lin You has created several acquisition lists.

[Buying: Undead Bones, Price: 20 Copper Coins/Piece]

[Buying: Corpse Oil, Price: 30 Copper Coins/Serving]

[Buying: Copper ore, price 3 copper coins/piece]

[Buying: Clay, Price: 2 copper coins/piece]

Less than a minute after the list was released, players began selling it in bulk.

"Bone of the Dead x10" "Corpse Oil x5"

"Copper Ore x30" "Clay x20"

……

A series of transaction information flashed before Lin You's eyes.

He accepted everything without question, and the money flowed in and out like water.

The remaining balance of nearly 20 silver coins was quickly spent, with almost half of it gone.

But Lin You didn't feel sorry for her.

These materials were the raw materials for his production of copper keys and spirit lanterns.

Selling the copper key will recoup the cost, and the monsters spawned by the Summoning Lantern will give him experience and magic cards.

No matter how you look at it, you're not losing out.

"We still have quite a few copper key molds left, let's use them all."

Lin You walked to the furnace and put the copper key and clay in.

[Crafting complete! You have obtained 1 "Bronze Key"!]

[Durability of the copper key mold: 9/10]

[Crafting complete! You have obtained 1 "Bronze Key"!]

[Durability of the copper key mold: 8/10]

……

One copper key after another was taken out of the furnace and put on the trading market by Lin You.

Each one was priced at 1 silver coin, and each one sold out within ten seconds of being listed.

The money flowed in like water, covering the expenses incurred in purchasing materials.

"This business is even more profitable than mining."

The smile on Lin You's lips grew wider and wider.

He then took out copper ingots, undead bones, and corpse oil from the treasure chest.

"Make a spirit lantern."

Lin You walked to the basic worktable and put the materials in.

[Summoning Lantern: 5 Copper Ingots, 5 Undead Bones, 1 Corpse Oil, requires a Basic Workbench]

[Sufficient materials available, let's begin... Time remaining: 3 minute]

Three minutes isn't a long time.

Lin You waited patiently, and in the meantime, she made a few more copper key molds for later use.

[Crafting complete! You have obtained 1 "Summoning Lantern"!]

A strangely shaped lantern appeared in Lin You's hand.

The lantern's frame is made of welded copper strips, and its surface is wrapped with dark green vine patterns.

The lantern paper was made of some kind of translucent leather, with a pale, gleaming sheen.

Inside the lantern, a ghostly green flame burned silently, emitting a cold, eerie light.

……

【Spirit-Calling Lantern】

Grade: Level 3 (Green)

Light intensity: 75%

[Effect: When holding this lantern, the probability and intensity of encountering undead invasions increase.]

[Special Effect: Breaking a lantern will immediately trigger an undead invasion, limited to 10 times per day]

[Note: This eerie lantern is made from materials used by the dead. It will make the living feel uncomfortable, but it is a deadly temptation for the undead.]

……

"The light intensity is 75%, which is higher than that of torches and mine cart lanterns."

Lin Youti tried it in her hand and could clearly feel that the surrounding darkness was dispelled further.

But at the same time, a chilling aura seeped out from the lantern, spreading along his arm and throughout his body.

"It is a little uncomfortable, but bearable."

Lin You put the lantern aside and continued making the remaining two.

[Crafting complete! You have obtained 1 "Summoning Lantern"!]

[Crafting complete! You have obtained 1 "Summoning Lantern"!]

After finishing all three lanterns, Lin You held one of them in her hand.

The other two lamps were put into a treasure chest for later use.

"Ready."

Lin You took a deep breath and gripped the bronze sword tightly.

Flame Spirit has woken up from its slumber and is elegantly licking its paws.

Its magic has been mostly restored, and it looks to be in good condition.

"Flame Spirit, prepare for battle."

"Meow!"

Flame Spirit arched its body, the flames on its tail burning fiercely.

Lin You walked to an open space in the Earth's core and raised the Spirit Summoning Lantern high.

Then, he slammed him to the ground.

"Snapped!"

The lantern shattered, and eerie green flames spewed from the fragments.

But instead of scattering and splashing, the flames seemed to come alive and burrowed into the ground.

The ground trembled slightly.

Lin You could sense that something was awakening in the soil beneath her feet.

"They're here!"
