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

Lin You gripped his bronze sword and, leading the three mushroom monsters and the kobold miners he had just summoned, ventured deeper into the mine tunnel.

The newly summoned kobold miner walked at the front of the group, its steps more steady than the mushroom monster's.

Although it is also a summoned creature, it seems to retain some of its instincts from its previous life.

The rock walls on both sides of the tunnel became increasingly rough, and water droplets fell from above from time to time, making a crisp echo in the silent mine tunnel.

Less than two minutes later, they heard rustling sounds again ahead.

Lin You raised his hand to signal the summoned creature to stop, then turned sideways and pressed himself against the rock wall, peering forward.

About fifteen meters ahead, two dog-headed miners were squatting on the ground, constantly swinging their picks.

With their backs to Lin You, they were completely unaware of the danger behind them.

"Two... we can fight them."

Lin You quickly made a judgment and began to deploy tactics.

He ordered three mushroom monsters to ambush the kobolds in a side road on the left, intending to cut off their retreat.

The newly summoned kobold miners remain by your side, acting as frontal bait.

"superior!"

Lin You gave a low shout.

The kobold summon was the first to charge out, wielding a pickaxe and lunging at the two wild kobolds.

Hearing the noise, the two wild dog-headed miners turned around abruptly and let out a piercing bark.

"Woof! Woof!"

They raised their pickaxes to meet their charging brethren.

Three kobold miners collided, their pickaxes clashing and sparks flying.

Lin You did not give them a chance to fight.

He charged out from the side, his bronze sword aimed directly at the candle atop one of the kobolds' heads!

"Snap!"

The candle snapped and wax splattered everywhere.

The kobold panicked, dropped its pickaxe, and started spinning around in circles, clutching its head.

Lin You seized the opportunity and swung his sword repeatedly!

-13! -11! -15!

Several sword strikes landed, reducing the kobold's health to zero, and he collapsed to the ground.

You have killed 1 "Kobold Miners"!

[Experience points +20!]

Seeing this, the other kobold tried to run away.

But as soon as he turned around, he found that his retreat was blocked by three mushroom monsters.

The kobold was caught in a dilemma and had no choice but to grit his teeth and charge towards the relatively weaker mushroom monster.

A mushroom monster with low health was smashed flat by a kobold's pickaxe.

But Lin You quickly caught up and stabbed him from behind again!

-12! -14!

The bronze sword pierced the kobold's back, and it let out a scream, its body twitched a few times, and then stopped moving.

You have killed 1 "Kobold Miners"!

[Experience points +20!]

Current experience: 40/300

"Three mushroom monsters plus one kobold summon, four against two, the advantage is on my side."

Lin You shook the blood off his sword, then squatted down to pick up his spoils.

The two kobold miners dropped a total of 5 copper ore, 3 rags, and two worn stone pickaxes.

Lin You put them all into her backpack and then tried to make cards.

[Card crafting successful! You have obtained "Magic Card: Kobold Miner" x2!]

[Consumes 40 mana points, current mana: 243/320]

"Two more Kobold Demon cards."

Lin You nodded in satisfaction and put the new card away.

Although he lost a mushroom monster, his combat strength did not decrease, but instead increased!

Using war to sustain war is precisely the area of ​​expertise of the Card Master.

He didn't rush to summon those two cards as well.

The current team size is sufficient; too many summons would be difficult to control and could easily obstruct each other in the narrow mine tunnels.

Go deeper.

The mine tunnels became more winding and had more forks in the road.

With the help of his Eye of Insight, Lin You was able to spot the monsters hiding ahead of him every time.

In less than twenty minutes, he encountered four more waves of kobold miners, making a total of seven.

With summoned creatures absorbing damage in the front row, Lin You's output environment is very safe.

All seven kobold miners were killed, with none escaping.

You have killed 7 "Kobold Miners"!

[Experience points +140! Current stats: 180/300]

[Card crafting successful! You have obtained "Magic Card: Kobold Miner" x7!]

[Consumes 140 mana points, current mana: 110/320]

The magic power recovered somewhat over time.

In addition, the free attribute points Lin You invested were enough to support the consumption in the secret realm.

"I currently have a total of 9 Kobold Miner cards in my hand..."

Lin You glanced at the task list.

The first objective is to kill 10 random monsters.

The green "Completed" indicator has been lit up.

Progress has also been made on the second goal of mining five mineral sites.

Along the way, in addition to the first copper ore pile, he discovered four more mining sites on both sides of the mine tunnel.

Three copper mines and one iron mine.

The appearance of iron ore greatly surprised Lin You.

Iron ore is darker in color than copper ore, appearing as a dark red.

It gleamed with a metallic sheen in the torchlight.

……

Iron ore

[Note: Can be used to smelt iron ingots to create more advanced equipment and facilities]

[Additional Information: Iron ore requires a level 2 or higher pickaxe to mine and is a very useful and highly sought-after hard currency.]

……

Lin You used a copper pickaxe to dig open an iron ore vein, triggering the double-output effect of the Gold Miner's Ring once again.

You have obtained 2 piece of "Iron Ore"!

[Gold Miner's Ring effect triggered: Double production!]

You have received an extra "Iron Ore" x2!

You have obtained...

[Mining of 5 mining sites completed]

With the addition of the four mining sites and the first copper ore pile, Lin You has mined a total of five mining sites.

The second goal was also successfully achieved.

"Ouch... my backpack is a bit heavy."

Lin Youqing checked his backpack; he had mined a total of 63 copper ores and 21 iron ores during this exploration of the secret realm.

His leather backpack has a total of 10 storage slots.

Although they can be stacked, they do not reduce the weight.

These nearly one hundred or so pieces of ore, placed in the backpack, weighed several hundred kilograms!

With Lin You's current E-rank strength attribute of 20 points, it's not that he can't lift it.

But this will definitely have a serious impact on subsequent operations.

"Hmm...right!"

As Lin You pondered, his gaze drifted and landed on the kobold miner who was sticking out his tongue and waiting for orders.

"Isn't this a ready-made source of labor?"

He slapped his forehead, realizing that he was still limited by fixed thinking.

Who says summoned creatures can only be used for combat?

"You, come here, carry it on your back."

Lin You gave the kobold miner an order, and the latter obediently ran over and picked up the backpack.

Although it was a bit strenuous, the kobold miner managed to carry the backpack.

"Speed ​​and mobility greatly reduced... although I didn't expect it to continue participating in combat anyway."

Seeing the kobold's slow steps, Lin You casually took out two magic cards.

With a burst of light, two more kobold miners were summoned.

One is used as a porter, and the other two are used for fighting—a perfect combination.

"All that's missing is the white dragon horse."

Lin You made a complaint, then glanced at the remaining time in the secret realm.

[Time Remaining: 28 minutes and 34 seconds]

[You have achieved your objective. Do you wish to leave?]

[To leave the secret realm, you need to remain stationary for 10 seconds while not in combat.]

"There's still plenty of time."

Lin You did not rush to leave, but continued to advance deeper into the mine tunnel.

There's one more objective to complete the game—defeat the kobold overseer.

Since we're already here, there's no reason not to meet this guy.

As the mine tunnels deepened, the air became increasingly humid.

The sound of dripping water overhead became more frequent, and the soil beneath our feet became soft and muddy.

The torchlight was dim in the heavy humidity, but still within an acceptable range.

After walking for about five more minutes, the mine tunnel ahead suddenly opened up.

A huge underground space appeared before Lin You's eyes.

This space is twice the size of the previous mushroom cave.

In the deepest part of the space, a gigantic figure was surveying the surroundings with an arrogant air.

It is three times the size of an average kobold miner.

Its entire body was covered in rough, grayish-black skin, and its muscles were bulging.

The candle on its head was also much larger than that of a regular kobold, making it particularly conspicuous in the dark.

What it held in its right hand was not a stone pickaxe, but a bronze pickaxe with a metallic sheen.

【Kobold Overseer (Elite)】

Lin You's Eye of Insight activated automatically, and information appeared before her eyes.

But what made him frown even more was not the attributes of this elite monster itself.

Rather, it was the small figures scattered around it.

The torchlight swept across the area, revealing three ordinary kobold miners diligently digging nearby.

"One elite monster plus three regular monsters..."

Lin You took a deep breath and pulled out several magic cards from his pocket.

"Looks like I need to get serious this time!"
