Ye Xiao and Xiang Li Qiankun are both actionists who do what they say, and immediately open up a wide place under the sacred tree. Xiangli Qiankun took off the thousand caskets behind him, first turned into countless flying rulers to measure the length of the Demon Dragon Overlord's body, and then combined them into a flying carpet to weigh Erha's weight.

The Thousand Machine Boxes were once again combined into a tool table, and a special spiritual realm revealed light and shadow, in which the three-dimensional image of the Demon Dragon Overlord took shape. Xiang Li Qiankun pondered for a moment, manipulating various colors of spiritual threads to draw various patterns on the spiritual realm.

Ye Xiao watched dumbfounded, the wonder of the thousand receivers aside, even in modern society, it is an extremely priority mechanical engineer and 3D modeler, Mojia Technology is really leading the industry.

"Three hundred floating stones, three red flame gold stones, three heavy gold stones, five hundred pieces of blood bone wood, seventy liters of rebirth water, three sides of Sumeru sand, two thunder shock stones, and four superb spirit stones. Well, that's all you need. Xiangli Qiankun said to Ye Xiao.

"So many materials, but where can I find them now?" Ye Xiao had a headache, he also knew these materials as a formation master, but except for the spirit stone and the thunder shock stone, he didn't prepare anything else.

"You don't have it, I have it, but you have to charge money, I can help you make things, but you have to pay for the materials yourself." "Ye Xiao helped him eliminate the Flying Emperor Bee before, so he has already waived the production fee, but many of the materials are rare materials, and he can't be generous.

"Then you can count how many spirit stones. Ye Xiao thought about it, he also had a lot of spirit stones on his body, and there were some pills and materials that could be used to pay off the debt.

Xiang Li Qiankun quickly gave an answer after estimating in his heart, "A total of two hundred and eight top-grade spirit stones, you can erase the fraction, just two hundred spirit stones, a total of two immortal crystals." ”

"What? Two hundred top-grade spirit stones. Ye Xiao was frightened, two hundred top-grade spirit stones are equal to twenty-ten high-grade spirit stones, two million medium-grade spirit stones, and two hundred million low-grade spirit stones, how did Ye Xiao take out this huge amount of money.

"Floating Stone, Blood Bone Wood and Rejuvenating Water are all excellent materials, and I calculated them for you according to the lowest transaction price in the Three Realms, but I didn't give you a chance. You must know that the strength of this demon dragon overlord is already extremely strong, and if he has the ability to fly, it is even more powerful, and the price of two immortal crystals is not exaggerated. To be honest, I'm afraid that my processing fee alone will cost one Immortal Crystal, but firstly, you have been kind to me before, and secondly, I am also interested in transforming this demon dragon overlord, so the processing fee is exempted. But two immortal crystals are also a huge amount of money for me, and I can't reduce the material fee for you anymore. Xiang Li Qiankun said honestly.

Ye Xiao also knew that it was so simple to improve the strength of the Demon Dragon Overlord, Xiang Li Qiankun should be telling the truth, but he really didn't have that much money, even if he sold all the elixirs on his body, it was not enough. You must know that the two immortal crystals can even maintain the operation of the immortal weapon of Linlang Pavilion for a long time.

The Demon Dragon Overlord Erha could understand the conversation between the two, and the eyes on its huge head looked at Ye Xiao blankly. Ye Xiao was a little difficult to refuse, Erha has helped him a lot in recent days, and the so-called conscientious and conscientious has done his best.

"Brother Xiangli, this... Can you make an IOU? Ye Xiao naturally had some valuable things on him, but those were all things he couldn't sell. Unexpectedly, when he crossed over to the Three Realms, he would still face the dilemma of lack of money.

Xiang Li Qiankun frowned, "You are a person from the Barbarian Realm, you can't enter the Immortal Realm if you don't enter the True Immortal, and I will return to the Immortal Realm when the Sword God Trial is over, how can you repay the debt?"

"It's not a secret, I'm not a person from the Barbarian Realm, and when the Sword God Trial is over, I will also respect Mr. Order's order to go to the Immortal Realm to study, and then it's not too late for me to repay the loan slowly, even if I add some interest. Ye Xiao can only hope that Xiangli Qiankun is as friendly as Ma's father.

Xiangli Qiankun looked happy, "I said it earlier, it's easy to say that you can enter the fairy realm." The most valuable thing on your body is not a treasure but the Jizo Heart Fire, this thing is the best flame of the alchemy refiner, and I have many ideas that require the assistance of the Jizo Heart Fire, but unfortunately I don't have the same opportunity as you. When you come to the Immortal Spirit Realm, how about you use the Jizo Heart Fire to help me refine some treasures to pay off my debts?"

Ye Xiao didn't expect that his Earth Hidden Heart Fire would have such a high value, just by assisting in refining some treasures, he could offset the debt worth 200 million lower grade spirit stones. "In that case, it's a matter of word. ”

"It's easy to say, let's start refining the mechanical magic wings now, I also considered your Jizo Heart Fire in this plan, and you will also be on the side to assist in a while. Xiang Li Qiankun said excitedly, and then piles of materials were taken out of his space props. As a child of the Mo family, no matter where he goes, he carries a lot of materials with him.

The two of them soon became busy, Xi Su didn't dare to disturb and only sent someone to send some spirit fruits, the head of Baiyun Village stood on the tree and stared curiously at the busy two people below, a moment of fire, a moment of thunder flashing. After a full seven days, this special magic weapon was finally refined, it was a pair of huge mechanical wings, flashing with purple-gold light, suspended in the air, with clear bone lines and spiritual energy flowing back and forth.

"The Floating Stone is the core of its flight, the control of Immersion Gold can make it rise and fall freely, the Blood Bone Wood can make the wings more flexible and tough, the Rebirth Water can connect the blood of the demon dragon to the wings, making it one, Sumeru Sand can make the wings expand and contract freely, and the Red Flame Gold and Thunder Rock Stone make the wings have the effect of thunder and fire to assist in flight and attack. If the four top-grade spirit stones are exhausted, remember to replace them in time. Let's call this pair of mechanical magic wings the Thunder Fire Qiankun Wings!" Xiang Li Qiankun said, looking at his masterpiece.

"Erha, try the refining of the fast blood sacrifice. Ye Xiao urged, these days he has learned a lot of refining knowledge with Xiangli Qiankun, and has a deeper understanding of why his Jizo Heart Fire is so precious, this mechanical wing is originally a gold and wood structure, but because it is refined by Jizo Heart Fire, it has a few flesh and blood textures, which can make Erha more flexible control. Moreover, Ye Xiao also carved a lot of formations on this thing, making it faster and more powerful.

Erha excitedly spit out the essence blood in his heart to refine this pair of thunder and fire Qiankun wings, and as the blood flickered, the purple-gold wings were inserted into the back of the Demon Dragon Overlord, and the rebirth water combined with the blood of the Demon Dragon Overlord, making this pair of wings as if they were growing on his back. Erha spread his huge wings and soared into the sky, and a pair of wings flashed with thunderous light, and the speed was extremely fast. Then the wings turned fiery red again, and they burned into flames, becoming a pair of fiery wings. Erha excitedly circled the sky a few times before he reluctantly landed under Ye Xiao's urging. The mechanical wings instantly shrank, like a metal backpack, and it was completely unrecognizable as a pair of wings, which was the effect of Sumesha.

"I didn't expect that with the blessing of the formation, this pair of Thunder Fire Qiankun Wings is even stronger than I imagined, your formation level is so superb, it seems that I will not lose anything in this transaction. "Xiangli Qiankun didn't expect that in addition to the Dizang Heart Fire, Ye Xiao also has extremely profound formation knowledge, although he is also good at formations, but it is to assist in refining, and its depth and breadth are not as good as Ye Xiao.

"Erha already has wings, and there is a place for those flying queen bees, so we can go deep into the giant bee's nest to find out. Ye Xiao urged, he wanted to finish these trivial matters as soon as possible, so that Xisu's village would not be harmed.

"Don't be in a hurry, we've been busy all day long, so let's rest for two days and then go." Xiang Li Qiankun suggested.

But I heard an urgent report from Xi Su that the flying royal bee is here again, and this time there are more than last time!

"The breeding and recovery ability of this flying royal bee is also terrifying, it's only been a few days. "Both of them have big heads.

The Demon Dragon Overlord took the initiative to ask, Ye Xiao nodded, and Erha spread his wings excitedly, soaring into the sky, intercepting the giant bee swarm in a very far place.

The wings of thunder swept by, and countless flying king bees were numb by the electricity and fell to the ground one after another. And the wings of flame swept by, and countless giant bees were burned to ashes by the blazing flames. The most terrifying speed and toxin of the flying king bee were like a joke in front of the Demon Dragon Overlord, and the tail spines of the giant bee could not penetrate Erha's thick skin at all. In addition to the giants and a very small number of giant beasts, the Demon Dragon Overlord was already standing at the top of the food chain, you must know that Ye Xiao did not dare to fight it head-on, and the Demon Dragon Overlord with wings would only be more powerful.

After a big battle, Erha returned to Ye Xiao's side unharmed to ask for credit, and the Flying Emperor bee colony in the distance was wiped out. Looking at this rich battle fruit, Ye Xiao smiled with satisfaction, these two hundred top-grade spirit stones are really not in vain.

Three days later, Ye Xiao and Xiangli Qiankun said goodbye to Xi Su and set off for the giant bee's nest.

Stepping into the Giant Mountain Range again, Ye Xiao's confidence is even stronger, but the strange purple mist in the sky still can't break through, Erha's Thunder Fire Qiankun Wing is still powered by aura, and the purple mist can block the operation of aura, which is extremely powerful.

"Does Brother Xiangli know what this purple mist is?" Ye Xiao asked curiously.

Aisato explained, "I have studied this purple mist, which is more of a spell than a substance, and once it is taken away from the Giant Mountain Range, it will turn into ordinary water vapor. I suspect that this giant mountain range has been spelled, and this purple mist is what holds back the giant, knowing that giants can also fly. The legendary Giant King was also sealed in the Giant Mountain Range, and this purple mist was most likely the key to sealing the Giant King. Have you noticed that the purple mist is much thinner than before? ”

Ye Xiao looked up at the mist above, and was really shocked, "Don't you say that I haven't found it yet, it's really a lot thinner, could it be that the Giant King is really about to break the seal?"

"I don't know much about the Giant King, but the Divine Stone is really wonderful, and I have studied it for a long time, but it is difficult to discover its mystery and principle. Xiang Li Qiankun replied again.

"How did those people from the Heavenly Domain cross this giant mountain range?" Ye Xiao asked his question again, he had been busy and forgot to ask Xi Su about it.

"I know this, and I also asked the village chief Xisu. As long as you grind the divine fruit into juice and apply it to your body, you can fly freely without fear of those purple mist. But there's more to traversing the Giants Mountains than just giants. At the beginning, Xi Su and his mother were chased by giant beasts in the Northern Regions, and had to enter the Giant Mountain Range, but they got lost, and finally crossed the Giant Mountain Range by mistake to reach the Southern Regions, and then they did not dare to go back after setting foot in the Giant Mountain Range. Xiang Li Qiankun explained.

While the two were chatting, the huge canyon appeared in front of them.

"Be careful, the giant bee's nest is just ahead, there are endless flying king bees guarding it, you and I have to be careful. Xiang Li Qiankun reminded.
