The refining furnace is based on the special Tianjing in the Black Water and White Mountains, and the total number of various auxiliary materials is calculated to be more than 100 kinds. If there were no sandworm miners and the abundant mineral resources of the Black Water and White Mountain, Fang Yan would not know how long it would take to collect them.

The celestial crystal is like a gemstone, extremely hard, no worse than the thousand-year-old cold iron, after the barbarians obtain the celestial crystal, polish it into a weapon, like a divine weapon, can be sold gold and jade.

Tianjing is hard and indestructible, it is a rare material, after refining, remove impurities, into a mung bean-sized Tianjing sand, a weapon, just add a few grains of Tianjing sand will make the quality of the weapon directly improve a level.

Even if Fang Yan had a sandworm mining machine, it was because of the coincidence that he discovered the celestial crystal vein, so he had the capital to use it to build a refining furnace, and the luxury was far better than that of dragon scale armor.

Under the refining function of the sandworm mining machine itself, after digging a vein, the collected Tianjing sand is only about twenty cubic meters, and the refining furnace will use thirteen cubic meters.

Inside the refining furnace, there are dense rune inscriptions, combined into a complex anti-yin and yang five elements gossip array, and the outside of the refining furnace is engraved with a positive yin and yang five elements gossip array, which is positive and negative, which can better gather spiritual power, block spiritual power and strengthen spiritual pressure.

The refining furnace has four legs, corresponding to the earth, water, fire and wind, depicting the magic array runes and inscriptions, playing an auxiliary role, and there are Zhou Tian stars corresponding to the Ding Lid, and the number of Tiangang.

The entire refining furnace can be said to be the pinnacle of Fang Yanji's own refining, this refining furnace itself is the height of the eighth-level magic weapon, if it weren't for the material and his own strength, Fang Yan even wanted to raise it to the height of the ninth-level magic weapon.

"It's not over yet. Feng Yu came to Fang Yan's side and handed over the scout ball. "I found traces of the barbarians, a team of 10,000 people returned to the city of the bald people, and there were many people guarding the front line, about thirty or forty thousand. ”

Lin Feng asked, "Our whereabouts must have been exposed, didn't the barbarians search for it?"

"We are only five of us, and the barbarians know our numbers, so it is impossible to send a large army to search for them, because this is not in accordance with the rules of profit. Fang Yan looked at the refining furnace in the array. "I'm almost at the last moment, at least a day to recuperate Yunling, you guys be careful these days, and come back first to inform if you find the traces of the barbarians, our purpose is not to kill the barbarians. ”

Feng Yu nodded and said, "I understand, but you have been refining the refining furnace for the past few days, when will we be able to implement the plan?"

"Sharpening knives is not mistaken for woodcutters, and I am pondering and researching during this time. You're not in a hurry to go back to the Guannai, are you?" Fang Yan said. "The barbarians have been preparing for so long, it is impossible for us to give up going south because we harassed their big rear, in other words, even if I cause a beast tide and destroy the Black Water and White Mountain, the barbarians will not change their original intentions, they will only give it a go, fight against the water, break through the barrier and go south, and get the benefits they want, the outside of the plug is very large, the Black Water and White Mountain is too small, and they can still live well if they change the land. ”

"As soon as you can, I hope to go back before the year. Feng Yu sighed.

Fang Yan persuaded: "Don't worry too much about this, what can a few of us do, everyone knows very well, no matter how great the ability is, it is not as good as the clan, the rules are like this, you don't have to be compassionate." ”

Feng Yu's expression became more and more solemn, and he turned around and walked out: "I'll go outside and take a look." ”

Lin Feng also followed: "Let's go together, one more person, more than one person." ”

After the two of them left, Senior Sister Hu said: "You don't seem to care much about the border war, haven't you thought about how much disaster it will cause after the barbarians go south, and Taiwu City may also be unprotected because of this?"

Fang Yan looked at the formation calmly and said: "In his position, I am just a small soldier, the sky has collapsed, there is a tall one, the border pass has been broken, someone has a headache for the Ming Dynasty, he can't do it, there are city lords who can't do it, and there are major clans on top, what does it have to do with me." ”

Without waiting for Senior Sister Hu to refute, Fang Yan sneered: "Do you think that's what I think, your father also thinks the same, those people are all like mirrors, they can see very clearly, but the butt decides the head, it's not what they think, what can be done, when you figure it out, come and talk to me again." ”

"You ......" Senior Sister Hu looked angry, but she didn't know how to refute it, because she knew it very well.

The situation in this world, the reason why Fang Yan can see it so clearly is also because of his previous life cognition. The current situation, like the battle of the Song and Yuan dynasties, the replacement of the Ming and Qing dynasties, are all alien invasions, although the situation is different, but the reasons are almost the same, all because of a sharp word.

The history of the previous life has already told everything, and it is precisely because Fang Yan knows these things, and when the two are compared, he will naturally be able to stand on the shoulders of the giants in the previous life and easily see the situation in this world.

There was no sound in the cave, and the atmosphere became solemn. After a while, Fang Fengbao ran back with a happy face.

"Brother Yan, look at what this is?" Fang Fengbao took out a spar from the storage bag. The storage bag is made of sandworm skin, with the inscription of mustard seeds in Na Sumeru, combined with the power of the formation rune, a storage bag can hold a volume of 1,000 square meters.

Although the storage bag is a good thing, it needs to consume true qi to collect items, and the storage bag itself also needs to be supplied with aura, otherwise the space will gradually shrink due to the loss of aura.

The same is true of the storage ring, this is when Fang Yan retrained and strengthened, and he realized that only because of the law of conservation of energy, there will always be loss.

"This is the Beast Bone Spirit Crystal!" Senior Sister Hu showed a hint of surprise, stepped forward to check it carefully, and after confirming that it was correct, she hurriedly asked. "If it wasn't dug by a sandworm miner, it can't be the only one, there should still be. ”

Fang Yan took the bone-like spar and observed it carefully, "Feng Bao, take out the other parts." ”

Fang Fengbao said with a smug face: "I found this, Brother Yan, you can't waste it." He said that he was a little reluctant to take it out.

The pieces of spar were taken out, and Senior Sister Hu immediately took it and put it together, and soon put together a three-meter-high skeleton diagram on the ground.

"This set of beast bone spirit crystals, at least the corpses of ninth-level demon beasts, are relatively intact, they look a bit like wurms, Feng Bao, take out the spirit crystal core. Senior Sister Hu looked at Fang Fengbao with a threatening posture.

Fang Yan said with a smile: "The beast bone spirit crystal only exists in the spirit stone vein, and it will only exist in the large spirit stone vein, according to the calculation of the back and forth law of the sandworm mining machine, it must have finished mining that spirit stone vein before coming back, you still have the spirit chalcedony in your hand." ”

Fang Fengbao said with an unhappy face: "I knew that I shouldn't have taken things out, I swallowed it myself, and the spirit crystal nucleus can be given, but the spirit chalcedony is mine, and my dragon scale armor depends on it, the spirit stone vein last time, Brother Yan, you swallowed it all, and you can't say anything this time." ”

Senior Sister Hu said impatiently, "Hurry up." ”

Taking out a jade box, Fang Fengbao said with a painful face: "To be honest, in fact, I would rather take out the spirit chalcedony than take it, but ...... Alas. ”

Senior Sister Hu snatched the jade box, and didn't care about Fang Fengbao, who sighed, and opened the box carefully.

A flash of spiritual light spilled out of the box, Fang Yan and Senior Sister Hu's faces changed in an instant, and the jade box closed in an instant.

Fang Yan rushed forward and grabbed Fang Fengbao's storage bag: "Hurry up and give me a piece of spirit chalcedony, you loser, is there such a waste." ”

Senior Sister Hu also had a frosty face, and her true qi urged, and an enchantment shrouded the jade box and sealed it.

Take out a piece of spirit chalcedony, the demon lin sword appeared in his hand, quickly cut the spirit chalcedony, a jade box was made in an instant, and then the magic circle inscription was carved, and Fang Yan was completed like flowing clouds.

Fang Fengbao collected the spiritual chalcedony scraps discarded by Fang Yan with a painful face, sighing and feeling sorry for himself.

The new jade box was made, and Senior Sister Hu hurriedly handed over the jade box in her hand: "Be careful." ”

The jade box opened, and Fang Yan put a crystal-like bead the size of a dragon's eye into the jade box made of spirit chalcedony and lid it again. The two of them breathed a sigh of relief.

Senior Sister Hu looked at the beast bone spirit crystal on the ground and said, "Unexpectedly, we all underestimated it." ”

Fang Yan put the spirit chalcedony box into the ring and said, "There is a large array in the cave to help hide it, there should be no leakage of breath, right?"

Senior Sister Hu was also a little scared and uncertain: "Maybe not." This thing was dug up until it was found by Feng Bao, and if it was going to leak its breath, it would have leaked out long ago. ”

Fang Yan said with a frightened face: "If you are not afraid of 10,000, you are afraid of what happens, you and I know how attractive this thing is, with it, we don't need to set fire to the mountain at all, we just need to take it out at the bottom of the mountain, which is enough to make the demon beasts on the mountain move." ”

"You are going to die, go yourself, and don't take us with you. Senior Sister Hu said with a cold face. "If you really want to do this, I'm afraid that those demon beasts will chase you to the ends of the earth. ”

Fang Fengbao said: "You guys are making a fuss, is it necessary, the spirit crystal nucleus aura is hidden, and the slightest breath is not revealed, if it weren't for the beast bone spirit crystal, I can't be sure that it is it, before activating it, even if it is placed in front of the demon beast, it may not be recognized." ”

Senior Sister Hu said with a blushing face: "It was already emitting aura just now, although it was not fully activated yet, but I sensed it." ”

Fang Fengbao looked at Fang Yan, seeing that his face was also a little solemn, knowing that this was true, his expression suddenly changed greatly: "Then what are you waiting for, don't run away quickly, when will you wait, this thing will start to exude aura, not to mention a radius of thousands of miles, the demon beasts within a hundred miles will definitely be able to sense it, if we don't run away, we will have no way to escape." ”

Fang Yan pressed his shoulder and said, "Don't panic first, Feng Yu and Lin Feng are outside to control the wind, and they haven't moved, then it's definitely okay, don't mess around." ”
