At this time in the mine, except for Long Yu, the other five martial artists including Deng Yuan all had the cultivation level of Tianchu Realm.
The five people each used their own methods, and the power of the laws of heaven and earth that they had comprehended condensed into a beam, which rushed towards the fork in the cave ahead and soon drilled out several small holes.
Long Yu could feel the strength of these five Tianchu realm martial artists. Under normal circumstances, a single strike from them would probably be enough to blast a mountain apart.
But now, in the cave of the Nightmare Mountains, only a few small holes the size of fingers were blasted out!
One can imagine what the composition of this entire Nightmare Mountain Range is like.
"Everything in the world has different hardness. The material of the Nightmare Mountain is nothing. The forging material of my Dragon Skeleton Ancient Pagoda is really hard. Only the strong ones in the Kingly Secret Realm can cause a little crack in it..."
Long Yu thought in his mind, and then he used the power of the Taiyin Law that he had comprehended, trying to condense it into a beam and hit the wall of the cave in front of him.
The penetrating power of the condensed force will naturally be stronger, but this time, Long Yu was unable to leave any marks on the wall of the cave!
This made Long Yu squint his eyes. The hardness of this cave was really beyond his expectations.
Naturally, his situation was noticed by Deng Yuan and the other four people.
"Tsk, I thought the guy appointed by the general himself had some special ability, but I didn't expect that he couldn't even make a mark on the cave wall!"
"Then why do we need this kid? Let's get him out of here as soon as possible. Otherwise, if we dig up something, won't we have to share it with him?"
"That's right, Deng Yuan, you are our team leader, hurry up and tell this guy to get out!"
Several people cursed out loud, looking at Long Yu with unfriendly eyes.
Deng Yuan looked at Long Yu, shook his head and said, "Brother Shan Gui, you see, it's not that I'm sorry for you, it's just that your strength is too..."
"I'll try again. I didn't use my full strength just now."
Long Yu narrowed his eyes and insisted.
He could understand these guys' feelings. After all, no one would be willing to bring someone who was useless to do things, especially when he had to share a share of the results of the work.
So, Long Yu said this and wanted to try again.
However, those people were not prepared to give Long Yu this opportunity.
"Didn't use all your strength? Boy, are you an idiot? Who would use all their strength when mining?"
"If you can only use all your strength to destroy the cave wall, how slow will the mining speed be? Let's go and don't slow down our progress. It's really bad luck."
"Get out and ask the boss to assign you to another team. Our team can't afford a useless piece of trash like you anyway."
These words are a bit impolite.
Not even giving them a chance made Long Yu very unhappy. Thinking of the sinister look in Deng Yuan just now, he decided not to go with them to avoid more unpleasant things happening later.
"Then I'll dig somewhere else myself."
Long Yu said this, then turned and left.
"Hahahaha, I'm dying of laughter. With your strength, you won't find anything even if you dig for your entire life!"
"Don't pay attention to him, let's do our own thing... If it was someone else who was more respectable, we would be afraid that he would take away our food. This guy is so weak, he can't take anything away no matter how hard he tries, so let him be."
Those people did not try to persuade him to stay and continued to mock Long Yu.
Long Yu didn't care at all. He turned and walked towards another fork in the cave, and soon put the noisy and mocking voices behind him.
Before turning around, Long Yu noticed that Deng Yuan had a look of joy on his face, but he didn't know what he was happy about.
Logically speaking, there's no reason for this guy to be happy about Long Yu's departure, right
Long Yu was secretly alert in his heart, and then walked towards another fork in the cave.
There are many forks in the entire mine, but most of them have already dug into a large area of gray metal wall and there is no way to move forward, so new passages must be constantly opened up.
Long Yu walked along the branch of the cave for about a hundred feet and reached the end. Facing him was a metal cave wall shining with a gray luster. It was much harder than the previous huge stone cave walls.
Long Yu was about to turn around and leave, but then he changed his mind and thought, just because others couldn't do anything about these gray metal cave walls, it didn't mean that he couldn't do anything about them!
"I have the Void Dragon Blade. There is no one around right now, so why not give it a try and see if I can break through these grey metal cave walls with the Void Dragon Blade?"
Long Yu's mind moved and he made a decision. He held the pitch-black Void Dragon Blade in his hand. An eerie and sinister aura flashed on the blade.
He held the Void Ghost Dragon Blade in his hand, activated the power of the Ghost character he had comprehended, focused on the blade, and then stabbed it towards the gray metal cave wall in front of him.
To Long Yu's surprise, these extremely hard gray metal cave walls were actually pierced through by the Void Dragon Blade in an instant!
You know, these gray metal cave walls are harder than the boulder cave walls. The boulder cave walls alone are extremely difficult to break through even for heavenly realm martial artists, not to mention these gray metal cave walls.
From the fact that they gave up the whole road once they dug up the entire gray metal cave wall, we can know that even the strong ones in the heavenly realm have no way to deal with these gray metal cave walls.
However, Long Yu held the Void Ghost Dragon Blade and condensed the divine text of the word Ghost, and was able to pierce it in one pierce!
"Haha, awesome, worthy of being an ancient-level warrior."
Long Yu's eyes lit up and he immediately became excited.
Other Heaven Realm martial artists can dig up a lot of good stuff just by mining slowly. So since Long Yu possesses the Void Phantom Dragon Blade, wouldn't he be able to blast open a passage at will
The mining speed is hundreds or even thousands of times faster than that of other martial artists!
Improving the realm of martial arts is Long Yu’s current main goal. However, now that the heart calamity has not yet arrived, all Long Yu can do is to prepare for the arrival of the heart calamity while improving his strength in other aspects.
If he could dig up some good stuff in the Demonic Nightmare Mountains and exchange them for some elixirs, combat weapons, or martial arts, that would be great for Long Yu.
Immediately, he held the Void Dragon Blade and began to stab at the gray metal cave wall.
After only a few stabs, he had dug out a large piece of gray metal. Feeling that there was no spiritual energy in it, he threw it directly into the Dragon Skeleton Ancient Tower.
The gray metal was extremely hard. If other people knew that he could cut it like mud, it would probably cause unnecessary trouble. So he had to be careful and not throw the gray metal away randomly.
After a few more slashes of the knife, Long Yu suddenly felt that an extremely rich spiritual energy of heaven and earth was emanating from behind the gray metal wall of the cave. It was more than ten times richer than other places in the mine!
"Is there something good?"
Long Yu was delighted, and then worked harder. He directly condensed the divine text of the word "You" and used the Void You Dragon Blade to chisel through a very thick gray metal cave wall. Then he reached out and took out a green diamond embedded in the gray metal.
Long Yu used the Void Dragon Blade to carefully remove the gray metal, and soon a whole green diamond was revealed, emitting a rich spiritual energy that Long Yu had never seen before.
"What level of treasure could this be? Such a rich spiritual energy of heaven and earth will probably attract the attention of others..."
Long Yu immediately hid it in the space of the Dragon Skeleton Ancient Tower.
The Dragon Skeleton Ancient Tower is an independent space, and no one can feel the things hidden in it.
At this time, Long Yu thought of a rumor that had been circulating in recent days that people had been digging out a treasure called the Qingling Diamond in the Demon Nightmare Mountains.
Even if it is only a fingernail-sized piece, adding it when refining a war weapon can increase the hardness of the war weapon by at least twice, making it less easily damaged.
If the blue diamond that Long Yu obtained was the kind of blue-edged diamond, then it would be the size of a fist!
Once it gets out, it will definitely drive countless people crazy.
“I’m afraid that even the strong ones in the realm of magical powers have no good way to quickly cut through this gray metal cave wall. But I am lucky to have a sharp weapon like the Void Phantom Dragon Blade.”
There was a gleam in Long Yu's eyes.
He couldn't help but look forward to it even more. If he could practice a martial art that could be used for assassinations and sneak attacks, and combine it with the Void Dragon Blade, how powerful would that be
After returning here, Long Yu could consider exchanging the proceeds from mining for such a martial art, but he didn't know if he could find what he wanted.
Long Yu shook his head and didn't think too much about it for the time being. What he had to do now was to dig out as many treasures as possible from the cave wall.
No one would want to touch the gray metal cave wall, and this is exactly why Long Yu can get a great advantage!
The Void Dragon Blade exuded a deep and strange color, and Long Yu stabbed it into the gray metal cave wall again and again. Soon, he chiseled off a large piece of gray metal and threw it into the Dragon Skeleton Ancient Tower.
At the same time, he also obtained four fist-sized green-edged diamonds, which he put directly into his bag.
However, at this moment, when he dug out another green-edged diamond the size of a finger and wanted to put it into the Dragon Skeleton Ancient Tower, he suddenly heard a lot of chaotic footsteps behind him.
"It's the Blue-rimmed Diamond. It really is the Blue-rimmed Diamond. Damn, we are finally lucky. Hahahaha!"
"How did this guy make it? It's really amazing, but this is a bargain for us!"
Several extremely excited voices reached Long Yu's ears.
Long Yu turned his body and saw that the people coming were Deng Yuan's team of five. Perhaps they were worried about Long Yu, or perhaps they sensed some spiritual energy emitted by the Qingling Diamond, so they ran over.
Just then, they saw that Long Yu was holding a thumb-sized green-edged diamond in his hand, which immediately made them look greedy!
