The world is unpredictable, and it is difficult for Wu Yu to imagine what will happen in the future.

Nangong Wei treats herself like this, in fact, she should help her, and even avenge her. It's just that at this stage, even Nangong Wei herself doesn't believe that Wu Yu may surpass her.

Therefore, she wants to rely on herself more in this matter, as for Wu Yu, she just needs not to stop it.

The journey to Yin Yang Mountain made Nangong Wei's mood change with ups and downs, Wu Yu could deeply feel that the closer she got, the hatred in her heart would continue to grow, how much she used to love her mother, and how much she hated demons now.

"Sister Nangong, on this trip, I will definitely kill the demons, sacrifice blood to the sky, and avenge the hatred of the Sixth Master! One day, I will step on the endless demon sea and beat the infant emperor into ten thousand hells, so that he will not even die at peace!"

Beishan Mo was not far away, and he was angry and said categorically.

"Hmm. Nangong Wei nodded.

They can be regarded as growing up together and understanding each other, and in this regard, Beishan Mo is more active and decisive than Wu Yu.

In fact, Wu Yu sometimes wavered, he was clearly a person and a cultivator, why did he sometimes think about things from the standpoint of a demon? He didn't know if this meant betraying his own race, and he was even sorry for the Shushan Immortal Sect that cultivated him.

It's just that when he was young, the dreams of the Nine Immortals grinding his ears and temples had a really heavy impact on him.

All beings are equal.

They were actually quite pressed for time, so while remaining hidden, they quickly swept through endless mountains and rivers, shuttled through countless strange mountains and abysses, and leaped over many small sects in the blessed land, and finally saw the rolling endless demon sea in the north, which was an endless black ocean across the sky, and the pungent miasma, even the demonic qi could cover up, so who could know how many demons were hidden in this endless demon sea!

Some demons, after opening their spiritual intelligence, heard about the endless demon sea, and they tried their best to come here and enter the holy land in their hearts.

Not far from the vast, gloomy black ocean is the Yin-Yang Mountain, the southern side of the Yin-Yang Mountain, lush and green, and the north is affected by the endless demon sea, the living beings are silent, dark and damp.

Yin and Yang Mountain is very large, in fact, it is a slender and continuous mountain range, it is said that the 'Biluan Gold Mine' is also the trend of the mountain range, 'entrenched' under it, the number is much more than the beginning of the survey, if the entire vein is moved back, for Shushan Xianmen, it is also a great wealth, especially its core part, the existence of the Biluan Gold King.

Now the miners of Shu Mountain are in the core of Yin Yang Mountain, directly above the Biluan Golden King.

When Wu Yu and the others approached, they found that under a huge deep pit, there were at least dozens of miners, who directly cut with magic weapons, cut out the Biluan gold ore below, and put it into the bag of Sumeru.

And next to the deep pit, there were more than a dozen Shushan disciples with swords, most of them were Xuanjian level disciples judging from their clothing, and they were scattered around, responsible for guarding and vigilance.

When Wu Yu and them arrived secretly, a slightly mellow old man walked out of this group of people, his mood was excited, and he trotted all the way to everyone's eyes, only to see that the old man was very excited, and he knelt on the ground with a puff, and said reverently: "Liu Jin, a sword-level disciple of Shushan, has seen Nangong Wei and Beishan Mo, two Shushan wizards, and has seen Senior Sister Li Chuxue!"

Li Chuxue waved her hand and said, "Stand up." Don't get excited. ”

The old man couldn't help but be excited, some time ago he took over this task, and brought a group of people to mine the Biluan gold mine, this Biluan gold mine was actually discovered by the disciples of Shushan a long time ago, but because the amount was not very large, so it was not taken seriously, Liu Jin received this task, but he just wanted to make some merits, but he didn't expect to really investigate, but found that this Biluan gold mine was ten times as large as the registration, and even the existence of the Biluan Gold King.

Liu Jin was very excited, but he was worried that his strength was not enough, in case he met a strong demon, it would have to be cheaper for the demon, so he asked the Xianmen for help with a communication talisman, he never expected that the help sent to him by the Xianmen turned out to be the two recent future pillars of the Shushan Xianmen, one is the daughter of the sword fairy, and the other is the common disciple of the seven immortals of Shushan, Liu Jin felt excited to see them in this life.

When Liu Jin stood up and still bowed his head to Nangong Wei and the others, Li Chuxue took out the appearance of a team leader and said, "Calm down, introduce the current situation to me." How long will it take to finish digging?"

Liu Jin had already prepared, and said: "At present, it has been mining for a month, and I just knew that there is a Biluan Golden King, and I hesitate that Biluan Golden King is in the deepest part of the vein, so to dig it out, it normally takes about two months, after all, you can't forcibly destroy other Biluan Gold Mines Only take Biluan Golden King, this Biluan Gold Mine in Yin Yang Mountain, the added value is also very large, and it is estimated that it will take a year to dig it all out, but it says that you only need to stay until Biluan Golden King is unearthed, and the task is over." ”

Of course, if the time is urgent, then directly bomb and bomb, destroy all the Biluan gold mines along the road, and barely dig out the Biluan Gold King, but there will be a lot of waste.

Li Chuxue nodded, she didn't have to worry about mining, she was responsible for arranging guards.

"What about the secrecy, are there any demons attacking at the moment? Do the demons know that you are mining veins here? Can the demons know that there is a precious Biluan Golden King here?" Li Chuxue asked several questions in a row that everyone was concerned about.

Liu Jin smiled confidently and said, "We have very little movement, and we have arranged a blinding array nearby, and the demons obviously don't know anything about our mining veins. However, this place is close to the Endless Demon Sea, so there are usually a few little demons, and once we find out, they are basically slaughtered quietly. ”

In this way, the situation here is quite optimistic.

"I'll wait and see. Led by Li Chuxue, he personally went down to the deep pit to see the situation of the gold mining in Nabiluan.

Everyone went down together, and it was pitch black below, but with everyone's eyesight, they could still see the situation clearly, it was all dirt at the beginning, after all, the Biluan Gold Mine was very deep underground, and it was even no less than the underground Baoyue Furnace where Wu Yu was trapped last time.

In this process, Liu Jin has been secretly looking at Nangong Wei and Beishan Mo, his face is full of awe and envy, and he almost shakes his head and tail.

After about a quarter of an hour of decline, Wu Yu finally saw that the air below was empty, there was a kind of oil green in the dark, when he opened his eyes, the surroundings were full of turquoise rocks, and it seemed that everyone had arrived at a green starry sky, which was very gorgeous, these rocks were Biluan gold mines, and after being brought back and extracted, they could become pure 'Biluan gold', which could be directly used to forge magic weapons.

There are dozens of Shushan disciples, who are working meticulously at this time.

They cut the rock with their swords, trying not to destroy its spiritual patterns.

In the center of his feet, he could feel that there was a strong light that pierced through the heavy Biluan Gold and shot out from the distance, which was obviously the existence of the Biluan Gold King.

When a big man came, the disciples of Shushan naturally stopped their movements in unison, and looked at Nangong Wei and the others with awe-inspiring eyes, among which Nangong Wei and Beishan Mo were naturally the focus of the crowd, and even Li Chuxue's attention was far inferior to them. There is no doubt that they all envy Wu Yu's group of people, and it is conceivable that in time, as long as there are no accidents, they will definitely become big names in Shushan.

Li Chuxue took everyone around, and after a little understanding, she didn't bother to stay in this dark place. He greeted everyone and left with Liu Jin.

"Mine well, and after success, there will definitely be a lot of merit. Li Chuxue said solemnly.

"Yes!" In the face of this legendary Heavenly Sword-level disciple, the ordinary Xuanjian-level disciple was still in awe.

It took another period of time, leaving the deep pit, Li Chuxue was arranging some details in his heart.

Everyone fell next to the pit, and Liu Jin smiled: "Actually, it's not a big deal, after all, the demons don't know our actions at all, and your identities won't be revealed, you can just play around for a few days." ”

As soon as the words fell, not far away, Beishan Mo suddenly drank softly, his fingertips were a little bit, and suddenly an ice cube condensed in the air ten zhang away from everyone, and the ice cube instantly flew into Beishan Mo's hand, only to see Beishan Mo's expression was gloomy, and everyone couldn't help but look at it in confusion.

"What's wrong?" Li Chuxue hurriedly stepped forward.

At this time, Wu Yu saw that there seemed to be a fly in the ice, and the fly was flapping its wings and flying, and it was suddenly frozen, and it was estimated that it had frozen to death at this time.

"This is a demon who has opened his spiritual intelligence! It's just that the path is too shallow, and there is almost no demonic energy, but as long as it has spiritual intelligence, you can know that he is listening here! We can't just come here, there is such a little demon approaching, it is very likely, the demon has long been suspicious of this place, this Biluan gold mine may have been known to the demon, and even, our identity, may be known by the demon!" Beishan Mo said in an extremely serious voice.

"What!" Liu Jin lost his voice, for so many days, he had never paid attention to the flies and insects around him, but he still had some impressions, and suddenly remembered that he had seen flies for a few moments, but he didn't think much about it......

In this way, if this is sent by the demons to observe, the matter of the Biluan Gold Mine is estimated to have been exposed, and what is even more terrifying is that if their identities are also exposed, those demons who want to make great contributions to the demons will obviously flock to take the heads of Bei Shanmo and Nangong Wei.

The situation suddenly became urgent.

Beishan Mo can instantly discover this insignificant little demon, which shows that its ability is extraordinary.

After all, even Li Chuxue didn't find out.

However, Li Chuxue was not nervous, and said: "We are here to practice this time, and I am afraid that they will not come." We don't have to care about the exposure of our identities, we just need to do our best to kill demons. ”！
