Global Coming: Farming with my sister-in-law in the end times

Chapter 714 Unlocking the Locked Treasure Chest, Legendary Materials! (5600)

A greedy thought suddenly surfaced in Cao Xing's mind: he wanted to control this powerful alchemy technique for himself!
It's important to know that Mithril holds an almost unshakeable position in the forging industry.

Its powerful ductility and magical conductivity make it an essential material for crafting epic equipment or other items.

However, every material has its limits.

The same applies to Mithril.

In order to meet the forging requirements of some higher-level equipment.

Therefore, those legendary blacksmiths used their superb forging skills and rich experience to create this special material, the [Enhanced Mithril Ingot].

Enhanced mithril ingots have several times the ductility and magical conductivity of regular mithril, making them an essential material for crafting some legendary weapons and equipment.

The [Exotic Metal] developed by the Asura civilization has an effect almost equivalent to [Enhanced Mithril Ingot].

It has the same strength and excellent magical conductivity.

However, the Enhanced Mithril Ingot is an epic-quality material, requiring at least a thousand pieces of mithril and other precious materials to craft one.

In contrast, what are the raw materials for [Strange Metals]?
Iron, stone, and plant fiber are three materials that couldn't be simpler.

If I could master this technology, I could practically mass-produce [Enhanced Mithril Ingots]!

Thinking of this, Cao Xing couldn't help but sigh, "I already knew from the descriptions of some items that this civilization called 'Asura' was very proficient in alchemy."

"At the same time, they also possess extremely powerful golem-making technology."

"In other words, this civilization truly combined the power of magic and technology, and studied them simultaneously."

"And it has also achieved quite remarkable results."

This made him even more interested in this lost royal city.

While Cao Xing was pondering these things, his men had already ransacked the entire perimeter of the building.

They handed over their spoils to the lord.

[Obtained: 17525 Strange Metal Fragments]

[Obtained: 34 Strange Metals]

[Received: Damaged mechanical parts *5]

[Obtained: Expert-grade Energy Crystal (Used) *12]

【get……】

……

After a series of system notifications, Cao Xing's backpack was filled with a large number of miscellaneous items.

The most abundant items were naturally those [strange metals] and fragments.

It adds up to nearly two hundred yuan.

Cao Xing nodded in satisfaction and said, "The harvest was pretty good."

After all, the price of an Enhanced Mithril Ingot is quite unimaginable in the outside world.

He essentially got over two hundred yuan for free.

Then, Cao Xing's gaze continued to sweep around.

Their current location is equivalent to being in the lobby of this building.

Deeper into the hall, there was a large metal door that seemed to lead to another room.

The iron gate appeared to have been violently forced open from the inside.

A faint light shone through the twisted edges of the door frame, as if something was hidden inside.

Seeing this, Cao Xing ordered again, "Let's go take a look."

Upon hearing this, everyone immediately took action.

Braum once again led the way, carrying his large shield at the very front of the group.

The others followed behind him.

Soon, they entered the interior of that door.

A metal passage, about four or five meters long, appeared in front of them.

The walls and ceiling of the passage were also covered with many magical runes, emitting a blue light.

As they walked, the group curiously observed the runes around them.

They seem to follow some kind of pattern.

But after some research, I still couldn't figure it out.

Before long, they passed through the metal tunnel.

Before them, a spacious hall appeared once again.

This area appears much more chaotic than the main hall outside.

Various metal fragments and some instrument wreckage were scattered on the ground, and there were also craters on the walls caused by the impact.

It looks like the scene caused by some enormous creature awakening and rampaging inside.

Cao Xing glanced around and quickly said, "Everyone, let's do it the same way as before: search every corner of this hall and take everything we can."

"If you can't take it with you... then disassemble it and take it with you."

Before he could finish speaking, the Tauren chieftain raised his totem pole and smashed it down on a seemingly intact instrument.

Although Kane Burrows had only recently joined the territory, he quickly grasped its corporate culture.

The others also immediately sprang into action, knocking on the floor and dismantling equipment with practiced ease.

Even the mature and steady Qinong quickly grasped the technique, tapping and knocking on the wall, seemingly trying to remove the runes from it.

Only Lord Oran and Bai Zhi stood there somewhat awkwardly.

After all, they did not belong to Cao Xing's territory.

As outsiders, they wanted to participate in this 'plundering' operation, but they were also a little embarrassed.

Cao Xing was unaware of their thoughts.

He himself was also carefully searching every corner of the hall.

As he walked, Cao Xing suddenly noticed something different in a dimly lit area ahead.

Upon closer inspection, it was a large, pitch-black metal box!
This metal box is a full meter high and 1.5 meters wide.

Because the lighting there is so dim, it's easy to miss.

"Huh? Such a big box, what could be inside?"

He immediately became interested and quickly walked over to the box.

Then, a system notification appeared.

A locked loot chest has been found. You need to enter the corresponding password to open it...

……

Cao Xing was stunned for a moment, then asked in surprise, "We actually need to enter a password?"

Keep in mind, this was the first locked box he had encountered since entering this world.

All the treasure chests that were opened before could be locked.

But so far, he hasn't encountered a single one.

Cao Xing stared at the metal box in front of him and pondered in a low voice, "So... where do I enter the password?"

The next moment, a faint light flashed across the surface of the box.

Then, a digital interface appeared above.

"So that's how you input it? It looks similar to the combination locks on our planet Earth."

Although I know how to input it, there is still a problem.

That is, he simply didn't know what the combination to the box was.

After pondering for a while without success, Cao Xing called everyone over to think about it together.

However, everyone stared at the numbers on the large box, completely clueless.

At this moment, a peculiar idea suddenly popped into Cao Xing's mind.

"How about... we let Sarah just chop this treasure chest apart with one strike?"

Under normal circumstances, the bronze, silver, and gold treasure chests they encounter in the wild cannot be opened by force.

Even if you have the power to destroy the treasure chest, and forcibly break it open, the contents inside will be damaged by the laws and disappear into the spatial rift.

Cao Xing didn't know if this loot box had the same mechanism.

But there's no better way right now.

"Anyway, there's no harm in trying. At worst, we'll just lose one box."

Even if there were treasures inside, he didn't see them.

Therefore, even if there is a loss, it doesn't bother me at all.

Cao Xing made a hand gesture.

Sarah, standing behind him, immediately understood what he meant.

Then, she raised the Grim Reaper's Blade.

The dagger gleamed coldly in her hand, as if it could slice through the very air!

Just as she was about to strike with her sword, the war golem behind her suddenly emitted a mechanical, synthesized voice.

"Master... these loot chests... cannot be opened by force..."

Upon hearing this, Cao Xing quickly said, "Sarah, wait a minute."

The legendary assassin paused in his movements.

Cao Xing turned his head and looked at the golem behind him, seemingly realizing something as well.

The golem escaped from here, and the box also appeared inside the building.

In other words, this golem is very likely the guardian of this loot box.

Cao Xing asked, "Golem, golem... do you know how to open this treasure chest?"

The golem's mechanical voice announced: "Master... enter the corresponding password to open..."

Cao Xing glanced at the golem speechlessly and said, "I know I need to enter a password, but I'm asking you because I don't know the password."

The golem's eyes flickered, and it continued to explain, "The password... is recorded on those instruments in the inner and outer rooms..."

"Simply follow the steps to activate the programs on these instruments in sequence, and you'll get the correct password..."

“I can tell the master… the order in which the instruments are activated…”

Upon hearing this, everyone looked at the golem in surprise.

It seems unexpected that it could provide such detailed information.

This is equivalent to being given the formula to solve the problem during the exam, and then just copying it.

A hint of surprise appeared in Cao Xing's eyes, and he continued to ask, "Then what is the order?"

The golem's eyes flickered slightly again, as if it were thinking.

A moment later, it replied: "Master... I am no longer able to provide you with the correct activation sequence..."

"The instruments in both the inner and outer chambers... have all been destroyed..."

At this moment, everyone was slightly taken aback, and then they also thought of this.

When they were searching outside, they really went to great lengths, leaving no stone unturned.

So, while we were at it, we also dismantled those special glowing devices and obtained some [strange metals] and [energy crystals].

Unexpectedly, these instruments were actually related to the password to open the treasure chest.

Cao Xing rolled his eyes.

Helplessly, he asked, "Can't you just tell me the password?" Upon hearing this, the golem's two eyes on its oval head flashed with a red and a blue light.

The mechanical body made a 'clicking' sound as if it were engaged in some kind of intense program conflict.

"Attempting to... bypass the password protection protocol..."

"Core instruction conflict... unable to output directly..."

The golem was now stuck in a strange, frozen state.

It seems that Cao Xing's instructions conflicted with the golem's underlying instructions.

"Beep...beep..."

As a series of urgent alarms sounded, the golem's body twitched and trembled violently!

Elisa whispered, "Is Tie Yi going to self-destruct again?"

Tieyi was the name she gave to the golem, and she also learned Cao Xing's naming style.

Hearing this, the others also became a little nervous.

Fortunately, the golem returned to normal after only a few moments.

Its two eyes also regained their blue light.

"Crack complete..."

"Master, the password is 8724...2452...3552...2451..."

It quickly gave a sixteen-digit password.

Upon hearing this, a smile reappeared on Cao Xing's lips.

This demonstrates that his control over the golem even surpasses that of its creator—the Asura civilization.

Therefore, they directly bypassed the underlying defense procedures and learned the password to the box.

After all, strictly speaking, this golem was actually transformed through the power of the system.

No matter how advanced the Asura civilization's technology was, it could never compare to the system.

Meanwhile, upon hearing these numbers, Tong Chuchu had already squatted down next to the box and started typing them in rapidly.

As the last digit of the password was entered, the box made a crisp 'click' sound.

Then, the lid of the box slowly opened.

"Big brother, it's open!" Tong Chuchu exclaimed in surprise.

Upon hearing this, a smile appeared on Cao Xing's face.

"Well done, Chuchu."

He stepped forward and glanced at the contents of the box.

At a glance, you can see a large amount of dark blue metal at the bottom.

This thing is a strange metal.

There seem to be quite a few, probably no less than a hundred.

In addition to these strange metals, there were also a dozen palm-sized energy crystals and some special materials.

The most eye-catching of them all is a uniquely shaped cylindrical device.

It also combines the power of magic and technology, with magical runes engraved all over the surface of the metal.

Cao Xing waved his hand and put all these things into his backpack.

[Obtained: Exotic Metal (Gold) *112]

[Obtained: Expert-grade Energy Crystal *15]

[Received: 32 Derry Iron Steel Ingots (Orange)]

[Received: Ancient Wooden Plank (Orange) *35]

[Obtained: Ancient Weapon - Short-Range Space Teleporter (Gold) *1]

……

Upon seeing the contents of the box, Cao Xing's eyes gradually lit up with surprise.

"Huh? There are actually two epic-quality materials?"

Cao Xing had encountered the [Delhi Steel Ingot] before; it was a material used to forge legendary weapons!

He spent some money on the market to gather the materials needed to forge that legendary rhinoceros horn.

As for the [Ancient Wooden Plane] that follows, Cao Xing has never encountered it before.

With an expectant look, he glanced at the properties of the two materials.

【Delhi Steel Ingot (Orange)】

[Quality: Epic]

[Item Type: Special Material]

[Item Description: A reinforced metal crafted from iron ingots, steel ingots, eternal gold ingots, and mithril, possessing extraordinary hardness and near-perfect magic storage properties.]

[Item Effect: Can be used to craft core components for large golems, high-level mechs, and even legendary equipment.]

(Note: Forging 'Delhi Steel Ingot' requires Legendary Forging Technique.)
...

...

【Ancient Wooden Board (Orange)】

[Quality: Epic]

[Item Type: Special Material]

【Item Effect 1: 100 Ancient Planks can be combined into 1 Ancient Hardwood (Legendary)】

[Ancient Hardwood (Legend): A type of hardwood imbued with powerful spiritual energy, its hardness is beyond imagination, and it is one of the main materials used in some legendary buildings.]

(Note: Ancient Wood is also required to upgrade the Lord's Castle after it reaches a certain level.)
[Item Effect 2: Can be used to construct some high-level epic buildings, such as the Psionic Mage Tower, the Hall of the Fearless Knights, the Camp of the Valiant Warriors, etc.]

……

After reviewing the attributes of these two epic materials, Cao Xing's eyes lit up with realization.

"Not bad, the effect of this Delimo steel ingot is about the same as expected."

"It's like a super-enhanced version of the Hengjin Ingot."

"As for this ancient wooden plank, its effect has exceeded expectations."

100 Ancient Planks can be combined to create one Ancient Hardwood.

This hardy wood is also an essential material for upgrading legendary buildings.

Clearly, the loot box contained some pretty good stuff.

This also aroused Cao Xing's strong desire to explore the other buildings in this ruin!

After all, just by entering a building, one can obtain so many high-level materials.

In his view, this site is equivalent to a source of high-grade materials!
If we could also explore a few more buildings, then the trip would truly be worthwhile.

With an excited expression, Cao Xing glanced at the attributes of the last item.

Ancient Weapon: Short-Range Spatial Teleporter (Gold)

[Item Type: Special]

[Magic Energy Reserve: 1000/2000]

[Item Effect: Consumes 500 mana points to instantly teleport yourself forward 5-20 meters (adjustable). Cooldown: 25 seconds]

(Item description: One of the research achievements of the Asura Power Academy. Because of its low cost and ease of use, it is loved by many Asura people.)
……

"A small teleporter?" Cao Xing murmured to himself.

This thing can indeed play a significant role in certain special circumstances.

However, Cao Xing also has an item with a similar effect, which is the [Dark Crystal Ball] that the old witch gave him in the Witch Forest last time.

This crystal ball can open two short-distance teleportation portals, allowing them to quickly pass through barriers or dangerous areas when needed.

However, Cao Xing's strength improved rapidly later on.

They never encountered a situation where they needed to use it, so the crystal ball remained unused.

With that thought, Cao Xing put the teleporter into his backpack with satisfaction.

"Not bad, not bad, there are indeed many good things in the treasure chest."

Meanwhile, the others had already looted the entire hall inside.

They all handed over their spoils to Cao Xing.

With a large amount of materials being put into Cao Xing's backpack, the harvest here was similar to that in the outer hall.

It also contains over ten thousand [strange metal fragments] and dozens of complete [strange metals].

Add some energy crystals.

At this point, he had looted everything inside the building.

Cao Xing clapped his hands and said with satisfaction, "Let's go out and continue looking for other buildings."

After saying that, he prepared to lead everyone away from there.

Just then, Lord Oran suddenly asked, "Lord Cao Xing, how long has it been since we entered the ruins?"

Cao Xing stopped in his tracks, a thoughtful look in his eyes.

He replied, "It's been about two and a half hours."

"Then it should be close to midnight now, right?" Lord Oran asked.

After hearing this, Cao Xing looked up at the time displayed above his head.

Current time: 23:13...

As Lord Oran said, it is indeed almost midnight now.

Cao Xing told him the current time.

After hearing this, Lord Oran continued, "In about forty minutes, the fog in the inner city will erupt, and the fog inside will soon envelop the entire ruins."

"You know that kind of mist; it's extremely eerie and terrifying. Even legendary experts would get lost in it."

He paused for a moment, then tentatively asked, "How about... we rest here for a while and continue exploring tomorrow?"

After thinking it over, Cao Xing also felt that the Lord of Oran's suggestion was very reasonable.

Compared to the previous fog disaster, Cao Xing's strength has indeed seen a significant improvement.

But he dared not say that he was absolutely certain he could deal with the terrifying creature in the thick fog!
He nodded and said, "Okay, let's rest here for a bit."

Upon hearing this, everyone stopped in their tracks.

Cao Xing continued, "Bron, go and close the door."

Based on past experience, during periods of heavy smog and fog, doors and windows must be kept tightly closed, and no loud noises should be made.

Otherwise, even if you stay in the room, you might attract the attention of those strange creatures in the mist.

They might even rush into your room and drag you away, which is quite bizarre.

"No problem, my lord!"

The big guy responded loudly and rushed to the door in a few steps.

"Roar……"

With a low growl, he instantly entered the form of the [Founding Titan], and his already powerful body began to suddenly swell and grow larger!

Like an inflatable balloon, it expanded to over ten meters in the blink of an eye.
