"On what terms?" As soon as Elder Liu heard that there was still something to discuss, he immediately stood up.

"First, depending on the degree of accumulation of those raw materials, it is definitely not possible to do it in March or May, and I hope that the elders will be paid according to the time they are actually piled up." Han Nuo said neither humbly nor arrogantly.

"This matter ......," Elder Liu thought for a moment, "I can only give half of it." ”

"Why?" Han Nuo asked suspiciously.

"If you let the sect master know that it hasn't been cleaned up for two years, you won't be able to hang on the bottom of it." Elder Liu said helplessly.

When Han Nuo heard this, he immediately lost his temper, "That's ...... Half is half...... Then in the second condition, the elders must agree. ”

"But it doesn't hurt to say it."

"I want to know the principle of the thing we rode on when we came down, and if I could, I hope the elders would teach me how to make that kind of thing." Han Nuo pointed in the direction of the 'elevator'.

Elder Liu was stunned for a moment when he heard Han Nuo's second condition, but nodded and agreed. Next, he took Han Nuo to the raw material warehouse and picked out a few items from the mountain of raw materials.

"You see, this kind of rune, called the reincarnation charm, is engraved on the item, and when it is infused with spiritual power, it can make the item rotate. And this kind of rune ......" Elder Liu taught Han Nuo a few simple runes that could make things move, and Han Nuo learned it quickly, and he became proficient in it in a short time.

To be honest, things in the Immortal Cultivation Realm were too convenient, and Han Nuo originally thought that to make something that could be rotated, he would need to refine an item that looked like a motor, but he didn't expect that just painting and carving a rune would solve it. And those runes, although they look complicated, but if you look closely, they look a little like the patterns on the circuit board.

Han Nuo felt in his heart that there must be some kind of pattern in these runes, maybe each of their basic symbols had their specific meanings, but he didn't understand them now. However, he believed that in the future, he would definitely be able to understand the essence of it and become a qualified refiner.

And the motivation for him to become a refiner is that he hopes to one day build a mecha that can be driven in this world of immortal cultivation. For this purpose, he even directly rejected the invitation of an alchemy elder.

Two days later, the sound of ping-pong began to be heard from time to time in the raw material warehouse, and the curious Elder Liu probed his divine sense into this place, only to find that Han Nuo was methodically sorting the mountains of raw materials and placing them on some wood chips.

The pieces of wood moved forward in an even row, transporting what Hanno had placed on them to the different shelves. Once the thing fell, the wood chips would return to Han Nuo one by one, and so on, repeatedly. And on the ground not far behind Han Nuo, a shimmering formation was placed there, and the formation was inlaid with a few glowing stones.

"Boy, who taught you this aura flow array?" Elder Liu soon appeared in the raw material warehouse.

Seeing Elder Liu coming, Han Nuo didn't stop the work in his hands, and replied casually, "The formation in the Immortal Boat I copied." ”

"What?" Elder Liu was shocked in his heart, "You've only seen this formation on the Crossing Immortal Boat?" ”

Han Nuo nodded, didn't speak, and his eyes kept scanning the items that passed from his hand.

"And how do you know how to excite a moonstone?" Elder Liu continued to ask.

"So this stone is called Moonstone?" Han Nuo happened to pick up a stone in his hand that was the same as the stone in the formation. "I saw Mingjue drive the immortal boat, so I asked him to teach me."

"This ......" Elder Liu smiled noncommittally and shook his head, "Then what are you called these pieces of wood?" ”

"Conveyor belt." Han Nuo replied dryly. Elder Liu looked at him, then at the aura flow array on the ground, and opened his mouth, as if he had something to say, but after all, he left without saying anything.

Seven days later, Han Nuo appeared in Elder Liu's room, and this time Elder Liu did not lose his temper like last time, but sat upright looking at the stove in front of him. Han Nuo looked at his reddish cheeks, sniffed lightly, and sure enough, he smelled a smell of wine.

"Cleaned up?" Elder Liu asked knowingly, in fact, when he heard that there was no sound in the raw material warehouse, he already knew that Han Nuo had finished his work.

"Elder, the raw material warehouse has been sorted out, and this is the list of materials in the raw material warehouse." After speaking, Han Nuo handed a booklet to Elder Liu with both hands.

Elder Liu stretched out his hand and grabbed the booklet in his hand. "You've touched refining before?" He asked Han Nuo as he flipped through the booklet.

"Elder Yu, there was once a refining master in the lower clan. However, the family is down, and there has been no one with spiritual power for many years, and in the next generation, there are only some tricks that mortals can drum. Han Nuo said the identity he had made up before.

"Those Karakuri include the conveyor belt?" Elder Liu asked.

"It's one of them, it's just that it's simpler to make it with the immortal method." Han Nuo nodded.

"Where is that Karakuri now?"

"Elder Yu, when I was hunted down and killed, my skill of Karakuri has long been lost. If the elders want to, they can draw some below. ”

"You junior, you are not very ambitious, and you want to exchange those mortal skills for my alchemy skills." Elder Liu could see Han Nuo's thoughts at a glance, "Let me ask you, mortals don't have a spiritual light flow array, how can those Karakuri drive them?" ”

"It's simple, you can use wind or water power, but you can't rely on people." Han Nuo saw that Elder Liu was very attentive to the skill of cunning he had said, and began to think about it in his heart.

"So, this kind of Karakuri can also be powered by spirit stones?"

"It should work." Han Nuo nodded, only to see Elder Liu pacing back and forth in the room with his hands behind his back.

"How long will it take you to do such a set of Karakuri?" Elder Liu suddenly seemed to have made up his mind, and turned his head to ask Han Nuo.

"With the current ability, it will take about ten days to make a set. However, there is a problem that I don't know how to draw out the spiritual power in the spirit stone to drive mortal things to rotate. Han Nuo thought for a moment and replied.

"It's easy, just leave it to me, you tell me what you need, and come to me here in ten days." Elder Liu received Han Nuo's affirmative answer, and his face showed joy.

Han Nuo hesitated for a moment, took out a pen and paper to draw a drawing, marked the size and handed it to Elder Liu, and then said goodbye to him to prepare the materials he needed.

Ten days later, Han Nuo came to Elder Liu's room as promised. Under Elder Liu's gaze, he took out a set of assembled conveyor belts from the storage bag. The belt is made of wood, which is part of the wood chips from the previous time.

Seeing this, Elder Liu also took out the things he had made according to Han Nuo's request. It was an object that looked like a motor, with a spirit stone on it. Hanno installed it in a reserved position and then connected the gears on the 'motor' with the gears on the conveyor belt with a chain.

After assembling it, Han Nuo motioned to Elder Liu to drive the 'motor', Elder Liu pointed a finger and injected a faint aura into it, and then the aura on the spirit stone flowed into the 'motor', causing it to rotate, and the conveyor belt immediately started.

Elder Liu looked at the Karakuri operation in front of him, clapped his hands and shouted ingenuity. Han Nuo saw it in his eyes and was happy in his heart. It seems that the power problem of the mecha can be solved.

However, Han Nuo still had a question in his heart, so he turned his head to Elder Liu, who was carefully observing the specific structure of the conveyor belt, and asked, "Can Elder solve the confusion in the disciple's heart?" ”

"What?" Elder Liu didn't take his eyes off the conveyor belt and asked casually.

"I see that the moonstone that has entered our raw material warehouse has a dim light, and it seems that there is not much energy left, why is this?"

"Guess why I want to do Karakuri powered by spirit stones?" Elder Liu stopped to look at the conveyor belt and turned his head to look at Han Nuo, who shook his head. "This moonstone is a strange ore that comes out of the spirit stone mine by chance. If it is excited on a moonlit night, it can attract the moonlight, and even if it drives a flying boat like the Immortal Boat for a whole night, the energy lost is extremely small. However, this item is very rare, and sometimes an entire spirit stone mine cannot be excavated. Therefore, the moonstone reserves of our sect have been depleted a lot, and maybe in a few decades, our Immortal Boat will not be able to fly. Elder Liu said with some concern. ”

"That's why the elders want to find alternative energy sources?" Han Nuo finally understood Elder Liu's intentions. "But why can't we use the aura to drive the flying boat like we drive the flying sword?"

"To put it mildly, maintaining a façade costs a lot of money. To drive the Immortal Boat to fly all night, at least six foundation building monks or two Jindan monks are needed to provide spiritual power, and it doesn't make people laugh out of their big teeth when it is passed on? Elder Liu gave Han Nuo a blank look.

"Then you can't afford to use spirit stones." Hanno asks a realistic question.

"So, I wonder if you have a better way, or can you tell me all the tricks you know?" Elder Liu said slyly.

"What's in it for me?"

"This commission, I will settle the account for you for two years, and then accept you as a registered disciple to pass on all the knowledge I have in refining to you, what do you think?" Elder Liu also seemed to see Han Nuo's interest in refining weapons.

"If that's the case...... Han Nuo narrowed his eyes and thought for a moment, then turned around and knelt down and bowed, "Master is above, please accept the apprentice's worship." ”

One day half a year later, a loud sound came from the sky above Tianyun Peak. Countless flying swords in the Tianyun Gate rose into the air, and in an instant, they surrounded the place where the sound was heard. A purple-robed middle-aged Taoist appeared in the center of the crowd, his eyes staring in a certain direction, but that direction was empty.

The Taoist shook his head and raised his hand towards the crowd, "Let's all disperse!" ”

Seeing the Taoist order, those people in yellow robes flew down with their swords, and only a few people in green robes remained.

"Old Ancestor Hao, judging from this speed, could it be that the other party is also a Yuanying Monk?" One of the people in the green robe arched his hand to the purple-robed Taoist and asked, this person was none other than Lin Xiaoran, the head of Tianyun Sect.

"It's not ......" the purple-robed Daoist shook his head, "One Jin Dan, one Qi Refining." ”

"What?" The people in the green robe were shocked when they heard this, and several of them rushed here as soon as they heard the sound, but they didn't even see a human figure, but Hao Laozu said that the other party was just a golden pill and a qi refining cultivator.

Seeing everyone's reaction, Hao Laozu smiled bitterly, "Don't panic, it's from this sect." Hearing him say this, all the people in green robes were even more surprised. They glanced at the people present, and suddenly realized.

"Isn't it...... What good things did Elder Liu research? Look at the speed of that thing, no less than the escape of the Yuanying monk! Master Lin said with a happy face.

"Okay, don't guess, he'll know when he comes back, everyone disperse." Hao Lao Zu waved his sleeves, and instantly flew into the clouds and mist above Tianyun Peak with the light. The green-robed people looked at each other for a while, and then they all left.

At three o'clock in the morning, at the door of the Zangyun Pavilion, a young Taoist in a yellow robe was holding a scroll in his hand and was fascinated. At this time, a figure appeared in front of him, "Uncle Du." The man called out to him respectfully, and stood there with his hands. This person is none other than Han Nuo.

After a while, seeing that Uncle Du didn't react, Han Nuo raised his voice and shouted again. This time, Uncle Du heard it, and he looked up at Han Nuo with some abruptness. I saw that the other person was much thinner than when he first entered the sect, his face was much whiter, and there was a faint sickness on his body.

"It turned out to be Master Han's nephew, how did he become like this in just half a year?" Uncle Du asked with concern.

"Huh? What does it look like? Han Nuo looked at himself back and forth, but didn't find anything unusual.

"Thin, white." Uncle Du smiled.

"Oh, Uncle Shi refers to this." Han Nuo also smiled embarrassedly, "You can't see sunlight in the refining room all year round, so it's naturally white. ”

"It turns out that you went to the refining room, and it makes sense to lose weight." Uncle Du smiled knowingly, "The group of disciples who started half a year ago, now you are the only ones who have not come to receive the introductory exercises." It's only here now, could it be that Uncle Liu's raw material warehouse has finally been sorted out? ”

"Uh......" Han Nuo smiled again awkwardly, it turned out that Elder Liu's refining room had already gained a reputation. Uncle Mo is going to refinery the refinery room, and he still has palpitations at this moment. He smiled wryly and waved his hand.

Uncle Du laughed, as if he knew the bitterness in Han Nuo's heart very well, but in fact, it was not. What made Han Nuo's heart palpitate was not the legendary raw material warehouse, but a 'turbine engine' that he and Elder Liu had spent half a year refining it for.

It turned out that after taking Han Nuo as a disciple in the first place, Elder Liu pestered Han Nuo all day long to study some Karakuri that could be used as the power of the flying boat. After Han Nuo was pestered impatiently, he described to him the appearance of the flying machines on the earth one by one, from the propeller engine, to the turbine engine, and finally to the rocket booster.

Although Han Nuo, who is a military fan, knows a little more about these things than ordinary people, his internal structure is not very clear after all. But he couldn't stand this Elder Liu was a genius, and after listening to the principle described by Han Nuo, he began to pull Han Nuo to study it. Because the propeller engine was too slow, and the rocket booster was too fast, Elder Liu folded it and finally made a turbine engine after half a year.

And so, the scene in the early morning happened. Elder Liu mounted the turbine engine on a flying boat-like magic weapon and dragged Han Nuo into the air to prepare for their first flight test.

Han Nuo didn't expect that there were such immortals in this world who were not afraid of death, and before he had time to refuse, he turned into a light with the flying boat and flew away, and the huge roar of the moment the engine suddenly started quickly attracted Hao Qianwen, the Yuanying Elder who stayed in Tianyun Peak, but the latter didn't even see their figures, and only relied on his powerful divine sense to detect that the two of them had flown hundreds of miles away.

And Han Nuo, who was flying on the flying boat, was soon unable to cope with the strong air pressure, but fortunately, the flying boat itself had a weak shield barrier, so that Han Nuo could barely stabilize his body by running the exercises, seeing this situation, Elder Liu immediately unfolded his shield to protect Han Nuo behind him.

After that, there was a reluctant flight, because the speed was too fast, so even Elder Liu couldn't control the flying boat freely. The flying boat scurried around like a headless fly, reminding Han Nuo of a video he had watched on his computer before called "Movies Made After Three Years of Animation".

The flight lasted about two hours, and after running out of fuel, the flying boat finally stopped somewhere about three or four hundred kilometers away from Tianyun Peak. As soon as the speed of the flying boat slowed down, Elder Liu took out his flying sword, grabbed Han Nuo and floated in the air, and put the flying boat away.

Elder Liu, who had put away the flying boat, flew back to the sect with Han Nuo's sword all the way, and they met several groups of other sect monks who had come to check the vision on the way. Elder Liu had an expression that he was also coming to see the excitement, and he dealt with those monks very casually. And when those people saw that there was only Han Nuo who was only a sixth-order Qi Refining behind him, they really believed it.

After returning to the sect, Elder Liu threw Han Nuo in the Divine Residence Forest, and Han Nuo rested in the forest for a while before leaving for the mountain. When I returned to Feiyun Pavilion, I realized that as soon as Elder Liu came back, he was taken away by Master Lin and another blue-robed elder.

After that, Han Nuo, whose face was snow-white, returned to his residence and rested for a while, before he could barely suppress the feeling of dizziness and wanting to vomit. Thinking of his situation on the flying boat, he finally realized that he should learn some exercises that could protect himself, otherwise if Elder Liu played like this, he was afraid that he would not even have the opportunity to build a foundation and finish his life.

Han Nuo, who had learned from the pain, came to the Hidden Cloud Pavilion before the unitary time, wanting to obtain a spell from it that could unfold the shield.

"Uncle Du, do you have any exercises to protect yourself?" Han Nuo asked Uncle Du about it.

"The exercises that you beginner disciples can choose are limited to the three rows of bookshelves on the left side of the entrance door on the first floor of the Zangyun Pavilion. Among them, there are only some very basic attribute exercises, and there are no attack and defense exercises. Uncle Du patiently explained.

"How can I get the offensive and defensive exercises?"

"Redeem with the contribution of the sect, and each exercise on the shelf is marked with the required contribution value." Uncle Du looked at Han Nuo, "According to the situation that you have been in the beginner for half a year, if you apply for a sect task elsewhere, you can barely exchange for a low-level exercise now." But the refining room ......" Uncle Du showed a difficult look on his face.
