Surrounded by a large group of NPCs, Li Xu circled around the black stone peak and roughly understood the characteristics of this peak.

As Wei Cheng described, the mountain is made entirely of black rock, and the surface is extremely smooth, making it unsuitable for climbing.

What made Li Xu even more strange was that he hit the steel drill with a hammer and tried to build a temporary staircase as usual, but he only heard a clanging sound of sparks, but there was not even a trace on the surface of the rock

It's just stronger than steel, and this mountain is really different.

The more this situation happened, the more curious Li Xu became, and he had to figure out the secret hidden in this mountain.

After trying it, he stood under the stone peak and took out the various props in the package one by one

However, neither the Shovel is used to dig the ground, nor the Gravedigger Shovel is effective here.

The rocks on the pinnacles cannot be destroyed, and even digging a pit in the ground, as long as you dig to a depth of two or three meters, you will encounter a layer of black rock, which is laid in the ground like an iron plate, and it can no longer be excavated.

"Master, don't try it, there are not a few people who have tried it here for so many years, but no one knows what good things are hidden in this mountain." Wei Cheng said with a smile.

"Fight against fate, forget it, we will have a chance to investigate again in the future." Bing Xuexin also persuaded.

"Wait, I want to try again." Li Xu looked at the package, only the gold shovel was left unused, this treasure that can penetrate the rock, I don't know if it can still be effective here.

Just as a group of NPCs looked at each other suspiciously, he took out the weird long shovel from the package, aimed it at the stone peak in front of him, and stabbed it straight through

Burst!

Something unexpected happened

Unexpectedly, the gold shovel actually played a role again, easily penetrating the black rock that even steel drills could not be chiseled into, and suddenly inserted into the stone peak to a depth of half a meter!

"Ah, that's okay" Bing Xue Xin and Xiao Lu covered their red lips in surprise, looking at the scene in front of them in disbelief.

"Master, what kind of treasure are you?" Wei Cheng also asked in surprise.

"It's just a normal digging tool." Li Xu was also surprised by the function of touching the golden shovel at this moment.

This kind of tomb robbery tool, I didn't expect it to be so sharp

Suddenly, Li Xu remembered that the front end of this prop was a long mouth like a cylindrical beak, maybe he could bring out a little bit of something hidden deep in the middle of the rock, so that he could figure out what was inside.

bite

Li Xu did not hesitate to press the extension button and let out the long handle.

Then he immediately grabbed the long handle with both hands and quickly pulled out the gold shovel

After the long handle of the book meter was completely pulled out of the stone peak, the long barrel-shaped sharp shovel tip carried a tube of black stone core

Li Xu hurriedly tapped the ground with a gold shovel, knocked the stone inside to the ground, and then put away this treasure prop, squatted down and held the long strip of black stone in his hand

The method he is using now is like the exploration of ore veins in the professional knowledge he learned in college, and the miraculous effect of touching the gold shovel can penetrate several meters into the depth of the stone, and the situation that cannot be seen inside can be explored in a way that is guò.

This stone core was like a geological sample, revealing all the things hidden in the Smoke Shadow Peak in front of his eyes.

I saw that this stone core, which was several meters long, was still black stone three meters in length, but after three meters, it had turned into an earthy yellow strip-shaped object, shining with a faint yellow halo

This is

Li Xu looked at the stone core in front of him in surprise, and hurriedly checked the familiarity of the yellow object

Sulfonite Mine: A system resource, a dangerous ore that is very easy to burst, and will burn when it encounters an open flame

Ah, sulphurite veins?

Li Xu looked at the attributes of the stone core in amazement, and was suddenly pleasantly surprised

What is called a sulfonite vein, he only glanced at it and knew it in his heart.

This kind of sulfonite vein, just like sulfur saltpeter in reality, is an extremely important resource!

It can be used in medicine, rubber, matches and other aspects, but the most critical use is that it can be used as a military material to make gunpowder and bombs

Although the game is not a reality, the appearance of this sulfonite vein still makes Li Xu ecstatic in his heart.

No wonder Yanying Peak is shrouded in black smoke all day long, it turns out that this extremely flammable and dangerous resource is hidden inside the peak

A qiē mystery, because of this discovery, the truth is finally revealed.

But Li Xu couldn't understand, how could there be such a strange resource in the troubled times?

Could it be that the game designers deliberately developed this special resource to hide it in a corner of the map for players to discover and use?

But what can this resource do, it is difficult to really make zuò explosives

"Master, I didn't expect that there was a sulfur stone hidden in Yanying Peak, this is a good thing!" Wei Cheng said in surprise.

"Yes, this sulfonite is the most important resource of our human race, but I didn't expect us to find a vein." Bingwan also said in surprise.

"What is the use of sulfonous stones, and which of you can sue me?" Li Xu looked at the surprised group of NPCs curiously, and quickly asked suspiciously.

"The master doesn't know, our human army has been fighting against the armies of the beast clan and the demon clan for hundreds of years, and has been able to maintain a large advantage, and the sulfur stone plays an extremely important role in the middle." Wei Cheng said.

"Our Terran warriors are inferior to the Beasts in terms of strength and combat effectiveness, and they are not as good as the Demon Clans in terms of magic attacks, so the biggest guarantee that we can fight against the enemy lies in the help of various large machinery, such as the Flame Meteor Car, the Ten Thousand Arrow Ballista, the Thunder and other powerful machinery, but the source of power and attack power of most of the machinery is because of the powerful help of this sulfur stone." Bingwan explained with a smile.

"What sulfonite can do so much?" Li Xu asked in surprise.

"Master, Bing Wan is right, all war machines need power support, and sulfonite mines can not only provide sufficient power, but also make all kinds of powerful weapons, which are indispensable and important resources in large-scale battles." Wei Cheng nodded.

"Such a good thing" Li Xu's eyes lit up, he didn't expect to find such a valuable vein by surprise!

In this way, the importance of the entire post town has suddenly increased by dozens of times

Whether looking for a temporary place to live or the preciousness of a mineral vein, the city must find a way to protect it from anyone else.

"Fighting against fate, the sulfur stone mine is one of the most important resources of the Terran army, once it is discovered, it will build a fortress, send a large-scale army to station for protection, it is a treasure that must not be lost, you must find a way to guard this vein firmly, don't give it to anyone." Bingwan hurriedly said.

"The eldest sister is right, she is the combat hero of the Ice and Snow Legion, and she knows these situations best." Ice Heart nodded.

"I see, don't worry, I'll do my best to figure it out." Li Xu said with a smile.

"That's good, with this vein, it is equivalent to having a mountain of gold, and the benefits are unexpected." Bingwan smiled.

"But I don't understand the question, since the sulfonite vein is so important, how should it be mined, and how can it be used?" Li Xu asked suspiciously.

"Master don't have to be anxious, I am a mechanic profession, and after we come up with a suitable way to mine the matter, we will definitely tell you as soon as possible, as for how to use it, it will require a large number of mechanical drawings, as well as a variety of other resources, which I will slowly sort out and report to you in the future." Wei Cheng said.

"Okay, I'll take care of the situation here, and I'll find a way to repair the city in two days and build this place into a strong fortress, so that you can live here with peace of mind and develop this vein." Li Xu said with confidence.

Originally, he was just hesitating, not knowing whether to spend a lot of money to repair the city, but now, with the appearance of this vein, he has made up his mind.

"Understood, master." Wei Cheng said excitedly.

For a group of remnants, the loss of combat effectiveness made him completely a waste, but now he sees a new direction of struggle, which makes them excited one by one.

"Okay, you guys are busy, I'll take Xuexin out for a walk and prepare for the restoration of the city." Li Xu said with a smile.

"Master, we have also seen it in the past two days, and it is not as difficult as imagined to restore this city, and it does not cost too much money for materials, and there are many ready-made resources near us." Wei Cheng said.

"Ready-made resources, tell me about them, which ones can be used?" Li Xu asked in surprise.

The biggest problem that bothered him now was the large amount of gold and resources needed to repair the city, of which the cost of resources was a significant expense

In troubled times, players need to build various system buildings, which require a huge amount of basic materials, such as logs and stone bricks, and if players do not have these materials, they will need to spend a lot of money to buy them from the system store, which will be a staggering astronomical amount

The official setting is very clear, if you want to build a territory that belongs to the players, you must have a large amount of money to do it, ordinary players can't afford to play these at all, and only the powerful army can accept it.

"Master, we are surrounded by stone mountains, the stone bricks we need can be collected nearby, and the wood we need can also be replaced by the hard stone pinnacles here, so that our city does not have to fear the enemy's fire attack, and the security performance is several times higher." Wei Cheng said with a smile.

"Very well, you guys hurry up and come up with a plan, and if it works, start implementing it immediately." Li Xu said excitedly.

"But master, there is still a problem, we need a lot of tools and manpower, only with us who lack arms and legs, I am afraid it will be difficult to complete such a huge amount of work." Wei Cheng said.

"Then you say, what do you need me to do?" Li Xu hurriedly asked.

Wei Cheng is right, if you want to mine materials, you must use tools, and you need a lot of workers to help, which is an indispensable preparation
