Luo Xin, who was full of doubts, followed Zirayi down one underground staircase after another, and the narrow and dark staircase was as bright as day because of the installation of the night pearl, exuding an icy cold glow, revealing a trace of coolness. As the depth deepened, the surrounding temperature became lower and lower, so that Luo Xin even had to use aura to keep his body warm, and all he breathed out was white mist.

Her bright gaze became more solemn because of this, and she wanted to use her spiritual sense exploration, but when she wanted to move, she was stopped by Zira, "Girl, for the safety of our lives, you better not act rashly." "I stopped moving, I thought he would say something like a warning, or explain what secret was hidden under it, but I didn't want him to stop talking after just one sentence, and continued to walk silently on the cold staircase.

Putting away the idea of wanting to explore, Luo Xin began to look in all directions and listen to all directions, however, as time passed, Luo Xin suddenly found that the surroundings were surprisingly cold, even if she was running the aura of her whole body to cover herself, she still seemed to be standing naked in the ice and snow, her 'lips' line was white, and her teeth were gordon up and down, cold, too cold, this cold is not a deviation of temperature in the real sense, but from the soul, yes, it is the cold of the soul, what is going on? What kind of terrible existence is there underneath? Thinking back to Zi Layi's expression of 'desire' and stopping, Luoxin's calm heart finally began to stir uneasily.

Finally, after Luo Xin himself couldn't remember how many flights of stairs he had walked, he stood in front of a huge stone 'door' that was as majestic as a mountain wall and carved with strange runes on it, in fact, it was a bit far-fetched to say that it was a 'door'. That is, the 'door' is connected to the surrounding wall without any gaps, except for two ears in the middle that can prove that it may be a 'door'.

Under the illumination of the pearl of the night. Luo Xin could clearly see the form and drawing of each rune, and even the blood-red background 'color' was particularly bright and 'colorful' under the action of the 'yin' cold light. If you don't look closely, at first glance, it seems that it is bright red blood is circulating back and forth in the integrated rune notches, judging from the lines of the runes, it seems to have been achieved overnight, without any pause, and the surface of the deep notches seems to have been made by some sharp weapon. Or maybe it's a person who has the kind of cultivation that can make a piece of dark iron look like this.

Dark iron is a treasure that all refiners dream of, no matter what grade of weapon, adding the dark iron, you can increase the quality by two levels, such as low-level magic weapons, adding the size of the nail shell can be upgraded to a low-grade spiritual weapon, and a low-grade spiritual weapon can be upgraded to a primary spiritual weapon.

Maybe there will be people at this time, if the Youtie is so strong. Isn't it true that there will be no low-level Dharma weapons in the world?

Hehe, the dark iron is not everywhere, legendary. Dark Iron, is an extinct ancient tyrannical beast - the bones of the 'Ghost Wart', they died through the land changes, turned over and over again were buried under the ground, and then after tens of thousands of years of earthly aura nourishment and transformation, turned into the Dark Iron, they are tenacious and unhurried, but soft and strong, everything in the world, can not find a sharp weapon that can overcome and destroy.

The dark iron is also graded. It is divided into King Beast and Minion Beast, and the bones of King Beast are naturally the purest of nature. It is also the strongest, and the bones of the minion are also very strong. However, its purity is more than twice as low. It is rumored that the wart is dozens of zhang high, more than 100 zhang long, but it can really be continuously corroded and ashed, and what is left in the end is a small and small part, so the amount of finished products is extremely low, and a bone weighing hundreds of tons may only be left with fist-sized iron in the end.

It can be seen that the rarity of the dark iron can really be called the name of 'miracle'.

However, it is such a dark iron, in front of me, it seems that it is not only the size of a fist, but a huge 'door' of dark iron that is dozens of zhang high and more than ten zhang long, if this can be taken away, it will be used to create the best weapon in the future.

Thinking so, "Gollum...... Grunt ...... "Who's swallowing saliva?" Luo Xin turned his head suspiciously and looked around? Except for her and Zilla, there was no one around, and there was little silence, and when he looked at Zilla's eyes with a smile, Luo Xin realized a little hindsight, as if this fool who looked at the big 'door' and swallowed saliva was himself.

Looking at the cold young 'girl' in front of her and blushing her earlobes, Zira couldn't help laughing for a while, and the posture of looking up looked wanton and cheerful, which was completely the same as the previous heaviness, which made Luo Xin look sideways again and again, and secretly wondered: Could it be that she did something funny? Is this old man worthy of laughing like this? Or is there nothing to pay much attention to?

"Girl, do you know the material of this big 'door'?" Finally finished laughing, Zira asked with a smile that had not completely faded away.

"Dark Iron! Known as the 'dawn' of the refiner! "Looking up at the giant 'gate' with a sigh, Luo Xin was reluctant to leave his eyes, because the 'temptation' and 'confusion' in front of him were really too big, and a small corner could cause all the martial cultivators and spiritual cultivators in the world to go crazy.

Not surprisingly, Luo Xin knew the material of the big 'door' in front of him, Zila rolled up his sleeves, and suddenly his smile was gone, and his face was replaced with a heavy one, he didn't look at Luo Xin, but said to himself: "Youtie is indeed the hardest 'door' in the world, and only the 'door' made by Youtie can completely imprison those ghosts!" Although Zira exerted all his strength to make his voice seem more ordinary, the almost invisible tremor still revealed the fear and panic in his heart at this time, and the dry hands in his sleeves subconsciously curled up and released, and then curled up again.

Ghosts? Luo Xin looked at Zirayi with some confusion, "What is it?" "Could it be those 'yin' evil things? Thinking of the 'yin' generals he had encountered, Luo Xin, who had some psychological 'yin' shadows, suddenly felt a chill down his spine, and his whole person stiffened.

"You'll know when you see it! Remember, do your best to protect your sea of knowledge! Zilayi's words made Luo Xin feel like he was waiting for someone else to take him to hell, and his hands involuntarily pressed towards the Qiankun bag on his waist.

Thundered...... The big 'door' decorated in front of her without gaps suddenly 'pumped' from the bottom to the top like the modern roller shutter 'door', and a cold 'yin' cold swept overwhelmed, Luo Xin only felt a cold breath binding her five senses, and she was frozen with a 'excited' spirit, and even her breathing was stagnant, and in front of her, she began to slowly uncover the terrifying truth. q――62270+dsuaahhh+24362291――>
