Black gold and dark iron is an extremely rare metal in the cultivation realm, and it is precious because of its rarity. Pen % fun % Pavilion www.biquge.info

This thing is the top refining material below the Jindan period, its texture is extremely hard, it is very suitable for arranging magic circles, and at the same time, the black gold dark iron also has a major property - conducting sound!

It is recorded in the Netherworld Rune that under the Jindan period, this black gold Xuaniron is the best material for refining the special magic weapon of the Netherworld.

The unique magic weapons of the Netherworld are collectively known as Nether Bells.

According to the focus of each monk, the magic weapon chosen by the monk of the Netherworld lineage is also different.

For example, Qingxin Bell, Miaoguang Bell, Taiyin Bell, etc., because the runes engraved on it by their owners are different, so that this magic weapon has different functions.

Therefore, what kind of magic weapon to use is ultimately up to the monk's own choice.

However, the black gold black iron is too scarce, and few people can get it, even if someone really spends a lot of money to collect it from various places, the quantity is very small, and it cannot be used as the main material of the refining weapon, at most it is mixed with it, which plays a role in enhancing the power of the magic weapon.

And now Xu Hao has a fist-sized piece of black gold dark iron in his hand, this unexpected joy is a bit big, Xu Hao took a breath and patted Xiao Zi's head: "Okay, you little guy, you did a good job this time, I will treat you well when I go back." ”

The little thing tilted its head proudly and squeaked twice, hum, you always look down on me, now you know how good I am.

Seeing Xiao Zi's appearance, Xu Hao shook his head funny, and then his eyes looked at the stone wall in front of him that had dug a big hole again, his eyes flashed slightly, and he groaned in his heart: "Look at the appearance of this black gold dark iron, it should be a rough stone, if you want to get the refined iron used for refining, you must be quenched and purified, and when the time comes, I am afraid that half of the impurities will be removed, and it is obviously not enough to refine the Nether Bell as the main material, but ......"

His thoughts paused, and the corners of his mouth showed a hint of arc: "But since it is a rough stone, there shouldn't be only such a piece of black gold and dark iron here." ”

Thinking like this, Xu Hao's hand moved again, and kept digging towards the stone wall in front of him, this time it took half an hour for Xu Hao to dig out a piece of black gold black iron the size of a pea, which made him a little disappointed.

Xu Hao even doubted whether his guess was correct, could it really be that this was the only one?

But in the end, it is better than nothing, not to mention the preciousness of black gold and black iron, even if it is a little bit, Xu Hao will not give up.

In the next few days, Xu Hao simply stayed in this cave, and in addition to meditating to recover his mana, the rest of the time was spent digging black gold and dark iron.

……

What Xu Hao didn't know was that just as he was devoting himself to digging treasures here, in the jungle hundreds of miles away from him, a young man wearing yellow clothes and a huge scroll around his waist suddenly appeared.

If Xu Hao sees this young man's clothes, he will definitely feel familiar!

As soon as the young man appeared, he took out a compass with a ball of light suspended above it, and a rag of light was in it.

He held the compass in one hand, then pinched the trick with the other, and at the same time chanted a complex incantation in his mouth.

After a while, the compass in the young man's hand burst out with blue light, and in the light cluster suspended above it, a slightly smaller cyan light cluster suddenly split, and it floated beside it.

The young man in yellow suddenly opened his eyes, a flash of light was fleeting, his eyes flashed with coldness, and he stretched out his finger a little.

Suddenly, the slightly smaller cyan light cluster seemed to have received an order, hovering in the air for a while, and after a pause, it suddenly turned into a streamer and rushed out in one direction.

The young man in yellow followed closely, and he didn't see any tricks he used, he only pinched a trick with one hand, and his speed skyrocketed, and he disappeared into the reckless dense forest in the blink of an eye.

……

This is already the third day, and the entire cave has been turned upside down by Xu Hao, the stone wall has been chiseled into pits, and the entire cave has been almost widened three or four times.

Fortunately, his efforts were not in vain, with the excavation, although he did not dig out the fist-sized black gold blackiron, most of them were the size of small stones, and the largest of them was about the size of an egg in the mortal world, fortunately, if the volume of these black-gold blackirons was combined, it was quite considerable, and the main body used to refine the Nether Bell must be about the same.

"I haven't dug up anything for half a day, and if I work harder, if I still don't, then I can only give up." Xu Hao thought so, and dug for more than half a day, when night came, and the roar of beasts came from time to time outside the cave.

Xu Hao frowned, ready to give up, and chiseled it again, but who knew that it was this time, and there was a pleasant sound of "ding".

Xu Hao was overjoyed, and dug out a small piece of black gold and dark iron, and when he saw its size, the joy on Xu Hao's face became a little stronger.

The previous black gold and dark iron were enough to refine a Nether Bell, but it was still a little reluctant, and the Nether Bell would not be very big, of course, it was not that the bigger the better, but if it was a few points smaller than the standard, it would definitely not be the best in terms of effect, and it was also unsatisfactory, which was not what Xu Hao wanted to see, but he had no choice if the materials were not enough.

But now it's good, with this piece of black gold dark iron, at least refining a standard Nether Bell is enough.

To say that people's minds are also strange, for Xu Hao before, this extra piece is already a luxury, he didn't dare to force it, and now he has what he wants, but he hopes to get more......

After all, there is another piece of black gold and dark iron here, and it is hard to guarantee that there will be no more in the future, so it is a bit stupid to give up like this.

Another night passed, and in the early morning of the next day, Xu Hao finally stopped.

"Presumably, the black gold and dark iron here have been dug up!" Xu Hao shook his head regretfully, after digging up two slightly smaller pieces of black gold black iron again, his luck seemed to have run out, and he didn't appear again, and now he can only give up.

"These black gold black iron are more than enough to refine the Nether Bell." Xu Hao is still very satisfied with this achievement.

Then he was about to leave the place, and when he turned around, he saw two giant bear cubs who were unconscious on the side, they had woken up many times over the years, but Xu Hao had fed them some of the flesh and blood of the demon beasts, and then knocked them out again, so as not to keep yelling at him, the enemy who killed his mother.

Xu Hao thought about it, waved his robe, and the two little bears slowly woke up, they were still a little dazed at first, but after they woke up, they yelled at Xu Hao fiercely, even if Xu Hao had fed them, they couldn't erase their hatred for Xu Hao.

Xu Hao didn't have the heart to pay attention to them, and when he saw them wake up, he turned around and walked out of the cave, it was already merciful not to kill, and whether they lived or died in the future would depend on their own creation. (To be continued.) )
