"Jingle Bell" ......

There was a faint sound of iron tools hitting rocks from somewhere, and the two of them listened attentively, but the sound was ethereal and intermittent, so strange.

When I walked around, I heard it clearly, but I stopped and listened carefully but found nothing, as if I heard someone call in a dream, and woke up to find that it was a conjecture.

After walking for a while, he found that this place was originally a gold mine, and the sand on the ground flickered with golden yellow light from time to time, but Yan Bingbing didn't think so.

She said softly, "There is not only gold here, but black ironstone is the most precious ore compared to gold. ”

Since Xu Ning met Yan Bing, he found that she was not wearing any gold and silver jewelry, and Zhu Pingzhai rarely saw such a jeweled thing as gold, the underground ancient city has such a huge mining area, but the buildings are also quaint and atmospheric, and there is no decoration such as gold and silver at all. The ancient people who thought that the wilderness land rarely communicated with the people of the Central Plains, and things like gold and silver were not too useful.

Yan Bing said again: "Black iron stone is extremely rare, it is priceless, it is an excellent material for forging weapons, and it can greatly improve the purity and power of the soul of the weapon. ”

Xu Ning didn't know anything about weapon smelting, and now he knew that other races and demon races outside the Central Plains were very successful in this regard. The "Heavenly Bow" in Yan Bing's hand and the "Soul Searching Furnace" they were looking for now were enough to prove it.

The faint blue light began to emerge from the darkness again, like tentacles extending from the front.

The sound of "clanging" also intensified, as if it was next to the two of them, and it seemed to be somewhere far away.

Xu Ning was horrified in his heart, and carefully explored the direction of the source of the sound.

"Look ......"

Yan Bing pointed to a place, his face turned pale, and he said tremblingly.

At the fingers, there were clearly several shadowy blue figures waving iron tools and constantly smashing them towards the rock wall, making a "clanging" sound. These figures are just digging and ignoring other things.

Xu Ning was shocked at first, and then felt surprised, and after looking at it for a long time, he found that these blue figures had been mechanically maintaining the same movement, without any change.

"Those figures are just illusions." Xu Ning said.

Sure enough, as the blue light drifted away to other places, the digging figure disappeared again.

Yan Bing rubbed his eyes, he still couldn't believe it, but it was pitch black in front of him, and there was still half a figure left, and there was no sound.

Although she is a descendant of the ancient clan, it is also the first time to come to the hinterland of the underground ancient city, and she has heard about the situation inside from the mouth of the old man's predecessors, and she can't react for a while.

The further you go, the thicker the blue mist becomes, and when you get to it, the ghosts around you are messy, and there are mining figures everywhere, and the sound of "clanging" is deafening.

Yan Bing panicked in his heart, took out a purple talisman seal from his arms, and was about to cast a spell, Xu Ning hurriedly stopped: "Bing'er, these illusions do not pose any threat to you and me, it is estimated that this place is strange and will stay as phantoms, so don't act rashly, in case it leads to bad signs, it will be troublesome." ”

Yan Bing obeyed him, took the purple light talisman back into his arms, and continued to walk forward.

From time to time, earth fell from above, and many of the top trees used to support them had rotted, and it was estimated that they would collapse if there was another earthquake, so the two of them did not hesitate to find a tunnel and walked in.

The tunnel was also dug by hand, and was littered with rotting wood and some iron tools for reinforcement, and after a gentle walk, it turned into a climb again, apparently leading to the cave outside.

The two of them no longer tiptoed up and quickly went up, and in a moment they arrived in a clearing, and a bright white light in front of them was very dazzling.

The stars above the head are dotted like gems that shine brightly.

The two exclaimed almost at the same time: "It's Starlight!" ”

They were now standing in an open field, surrounded by towering black peaks that were tightly shielded from the sky, and when they looked up from below, they could only see a small piece of the sky.

"This ...... What is this place? Xu Ning asked, staring blankly at the stars in the sky, "Could it be that we came out again?" ”

"No, this is not Tianchi, it is estimated that I have walked to some hidden deep valley." Yan Bing replied.

This is indeed not Tianchi, although it is also very empty, but it is too small compared to Tianchi, not to mention that there is no honeycomb dense cave on the mountain, and the ancient trees are towering, the long grass is miserable, under the blowing of the wind, swaying from east to west like a hideous living creature, the strong wind in the pit is blowing in from this deep valley.

The two of them were stunned for a moment, and when they calmed down, they found that there was a black building in the distance, so they quietly passed.

This is a temple that is quite beautifully built, and unlike the buildings in the Central Plains, the temple is made of black boulders, and it is said to be exquisite because the four huge stone pillars standing around it are carved with intricate patterns, birds and animals are lifelike, and flowers and clouds are quite vivid.

The Demon Slayer Lock in Xu Ning's body trembled suddenly!

"Be careful!" Xu Ning's expression became grim, and he said in a deep voice.

"Be careful, boy!" An old voice was transmitted to Xu Ning's mind through his divine sense, "The old man suddenly felt that there was a force that wanted to suck me out of the Eighteen Demon Slaying Locks. ”

It turns out that the master has also noticed it, and it seems that the soul searching furnace must be here!

The two of them were on alert, and slowly approached the temple, the grass and trees on the ground grew, and from time to time they touched some dead people, as if they had just died, and the corpses were well preserved without the slightest decay and damage.

"It seems that the demonic aura of this soul-searching furnace is extremely powerful, not only can it reforge the flesh, but it can also keep the corpse from decaying within the coverage of the demonic qi." Xu Ning saw this scene, and felt more and more that he would definitely destroy it in the future.

When I got closer, I found that the stone door of the temple was closed, and when I was hesitating, after a loud sound of "bang", the stone door slowly opened.

The faint blue light rushed out from the open stone door, and in an instant, the entire vast valley turned into a blue ocean, enveloping both of them inside, and this strange fog was extremely cold, and the cold air penetrated into the pores and soaked into the bone marrow, as if falling into an ice cellar.

Yan Bing kept shivering, his teeth were tightly closed, his face turned pale, and he could barely support it.

Xu Ning hurriedly took out the Concentration Dew from her arms and directly asked her to take a small sip, Yan Bing's body was really cold, and he suddenly got better, and his face was ruddy.

Before Xu Ning could calm down for a moment, a fireball roared.

Xu Ning hurriedly grabbed Yan Bing and flashed out.

"Boom"!

Fireballs exploded on the ground, blackening a large patch of grass.

Blue Devils!

In the blue mist, black shadows with white blades kept flashing, and the corpses that had been lying in the grass were all standing up at this time, or with teeth and claws, or holding rusty weapons and bows and arrows, and surrounded the two of them from all directions.

All kinds of strange cries rang out in the bitter cold wind, and the huge deep valley became a huge tomb, and countless evil spirits wanted to devour the living!

Yan Bing no longer hesitated, taking advantage of Xu Ning's full strength to resist, he took out the "Purple Light Night Talisman" from his arms, recited the incantation, and the soul talisman turned into countless purple crystals flying and circling around in the valley, and then turned into purple light one after another, penetrating the blue mist.

Under the purple light, the immortal corpses that had just risen from the ground fell one after another, and their skin gradually withered and rotted.

It's just that those black ghosts and blue devils are still approaching in the sea of blue clouds, and their blue eyes flash from the black cloth with a death light as cold as Xuan Bing's nirvana, and they rush towards Xu Ningyan Bing like a tide of desperate recklessness.

The Eighteen Demon Exterminating Locks rolled up a violent whirlpool, dispersing the blue mist within a radius of tens of meters, forming a protective circle, and the Gang Qi was overwhelming and the sea was overwhelming, and the black shadow was dissipated and disappeared into invisibility as soon as it touched it.

Yan Bing is not to be outdone, she now has the magic weapon forged by the ancient people, which is really like a tiger.

The continuous white light from the Skyware Bow shot the fireball flying in the distance directly into the air, and the fireball burst open, and the sparks and white light splashed at the same time.

Xu Ning was greatly surprised to see her bravery, his understanding of Horcruxes had not been so important as tonight, and now it seemed that the improvement of a peerless weapon in Horcruxes was equivalent to the improvement of martial vein cultivation. The phoenix sound emitted by the Heavenly Bow in Yan Bing's hand actually had a terrifying power to deter demons, and in the back, her ability to control the Horcrux had greatly improved, and she became more and more proficient, and the speed of the arrow was staggering.

Her original archery skills were extremely exquisite, and the Heavenly Domain Bow was also considered to be the best use, shooting an arrow out of thin air, and the white light arrow shadow drew a perfect arc, straight into the blue devil's chest, and the blue devil's entire body suddenly burst open, turning into a cloud of blue light.

The slaughter was extremely tragic, but when the blue mist faded and the deep valley returned to calm, it was as if nothing had happened in the battle, and there were only a few rags on the ground and the pungent smell of sulfur in the air. Only the grass and trees that were still burning showed the fierce battle that had just taken place.

The two looked at each other and smiled, and were about to speak, when a hoarse voice came:

"I've been hiding in such a hidden and dangerous place, and you still won't let me go?"

Xu Ning was taken aback, and when he looked up, a white figure walked out of the stone gate and slowly walked down the stairs.

"He's a sorcerer!" Yan Bing gently told Xu Ning, a hint of fear flashing in his eyes.

It was also the first time she had seen a sorcerer in person, but in recent years she had been shuddered by all sorts of terrible rumors about this mysterious demon hiding in an underground ancient city.

"We're not here to kill you." Xu Ning said solemnly, "I'm just here to get one thing." ”

He had originally made up his mind before coming here, not only to bring back the furnace, but also to kill the demon magician, but now that he saw this person appear in front of him, he felt that everyone was innocent and innocent, how did he kill him. What's more, the mysterious person in front of him looked so old and weak.

He was just an old man, with long snow-white hair fluttering in the wind, a thin face half hidden in the dark shadows and half exposed to the starlight, and a wide white robe crackling in the wind.

There was no expression on his pale face, his eyes were dazed, and there was a little demonic aura in such a haggard old man.

"Old man......" Yan Bing's heart softened inexplicably, just looking at this old man for a while, there was no fear in his heart.

"Old man, we're just here to find something, and we won't embarrass you." Yan Bing finished speaking, and his voice was extremely soft, like a warm wind in a cold night.

The old man raised his eyelids, finally looked at the two of them, looked at them for a while, and said softly: "Since I didn't come to chase and kill the old man, I'm relieved." You're not looking for a 'Soul Searching Furnace', right? ”

"That's it." Xu Ning also got straight to the point, "You hand over the stove, we will never embarrass you." ”

"And what if I don't want to?" The old man's expression was still calm, as if he was just saying it casually.

Xu Ning's brows furrowed, and he was about to think of a way to deal with it, but Yan Bing said again: "Old man, give him the 'Soul Searching Furnace', we really have something urgent......

The old man laughed inexplicably, and his smile was extremely weird!
