Wuji Immortal Mountain, in the evening.

The sky is shining, and the clouds are splendid.

A huge round ball dyed with colorful colors rose from the peak of sorrow, fluttering and swaying with the wind.

Under the ball, there is a square square, the outside is simply decorated with some bamboo skin of the big wooden box, the box of four people, each in one direction, condescending to look at the beautiful scenery of Wuji Immortal Mountain.

"Wow~~~Senior brother~~~"

Seeing that Xiao Ah Zi was about to stick to himself again, Li Changan hurriedly reached out and pinched Ah Zi's little head in advance, and scared: "Don't jump, I haven't reinforced the bottom, don't collapse." ”

"Oh~" Ah Zi immediately obediently blinked a pair of good-looking smiling eyes, and honestly moved to Li Changan's side step by step.

"You don't have to be so careful, just don't jump up and down like a monkey. ”

As soon as Li Chang'an's words fell, he listened to the master Lu Laodao who was holding the dust on the side and asked: "Chang'an, this thing is very strange, but it is not blessed by any kind of Dao immortal power, only a fire burning talisman can be lifted into the air."

What is the reason?"

"Master, Master, I know. Ah Zi hurriedly replied: "This is because of thermal expansion and cold contraction." After the air explodes when it is heated up, the ball will fly. ”

Gongsun Tuo, who was on the side, shook his head with a smile and corrected: "Senior sister, what senior brother said is that the air expands by heat, not explodes. ”

"Hey, I said, scared. You girl, you can't remember a single sentence so simply, and you are still expected to practice until the butterfly transformation period before the Jiazi exam. Eh..."

"Slightly~~" As soon as he heard the master talking about himself, Ah Zi had a headache, stuck out his tongue, and immediately hid behind Li Changan.

Lu Laodao has been in retreat for alchemy for a longer time than before, and he has not been out of the pill room for nearly half a month.

If it weren't for Li Changan's big apprentice coming to invite him today, Lao Dao originally planned to close it for half a year and eight months. Before the Jiazi Hui test, each of the three apprentices refined a few pills for replenishment.

Hard work pays off.

After two months of trial and error, it was perfect.

After many test flight failures, unstable flights, and insufficient cruising range, the [Chang'an brand sightseeing hot air balloon] was finally launched today.

Although Lu Laodao is not very good at human feelings, his professional foundation is still very hard. As a Dan Dao master, knowledge points such as thermal expansion, after a little pondering, I will understand a general idea.

"It's... Is it really made of that 'fish belly', and why is it so bright and smooth?"

Don't say that it is the world, it is Wuji Immortal Mountain, and Lu Laodao has never seen such a strong and heat-resistant 'cloth'.

"Back to Master. Li Changan smiled and arched his hand: "Thanks to the master who went to Wanwutang to exchange for enough fish belly, otherwise Chang'an may not be able to find such a suitable material to make a sphere."

The fish belly was soaked with thunderwood powder and dragon tree pulp to retain and enhance its original resistance to water, fire and high temperatures, remove impurities and strengthen toughness, and also achieve the effect of easy coloring. ”

Lu Laodao listened to it and half understood, but he didn't bother to get to the bottom of it. He just smiled and nodded, and pondered this wonderful large round ball that could achieve the flying effect without mana and with only a fire talisman.

"Master, Ah Zi, Xiao Tuo, stand firm on your feet. ”

After Li Changan explained, he raised two fingers with his right hand and recited the incantation lightly, and another fire talisman at the top of the ball made a 'bang' sound. The hot air balloon picked up speed significantly and flew towards a rather high mountain.

During this period, countless disciples and disciples of various peaks were attracted to look around, and some immortal chiefs specially came in the clouds to check what was going on with this unknown object.

As a master, Lu Laodao stepped forward to greet the inquirer, smiling, nodding, and greeting a few words.

Before leaving, Li Changan discussed with Lao Dao, and in order not to attract too much attention, he said that this thing was made by Lao Dao.

Lu Laodao, who was not good at lying, has been taught by the big apprentice in the past few months, and he is already quite proficient.

In a few words, he sent more than a dozen waves of immortals who came to see the novelty.

When he was about to fly to the rather high peak, with a 'woo', a white bird emerged from the dense clouds and flew to the fairy next to the colorful ball.

The white bird, the lotus-colored skirt, the green silk and the half-drooping, the first beauty of the Wuji Immortal Mountain with bright eyes and bright teeth, cold and dusty, Izumo Mingyue, appeared in front of the four of them without warning.

And Izumo Mingyue seemed to be stunned for a moment when he saw the four people in the wooden box under the colored ball.

This micro-expression can also be seen by Li Changan. In fact, Izumo Mingyue's expression is very rare, and 90% of the time, it is expressionless.

Hong Kong Zhen, this fairy sister, beauty is really beautiful, and staying is really stupid.

The fans called her an iceberg beauty, but in Li Changan's opinion, she lacked some agility. The whole person looks a little wooden.

Sitting on Bai Luan's back, Izumo Mingyue's gaze brushed over Li Changan again, and he bowed his hand to Lu Wuxiang.

"Uncle Shi!"

"Xiao Ming, hehe..." Lu Laodao nodded and smiled.

Li Changan: ......

I really can't complain about Master's down-to-earth title. But... Hey?

Li Changan suddenly noticed a detail that he had overlooked.

I still remember the first time I was outside the mountain protection array, when I met for the first time, the master saw this wooden beauty, and it was also this kind of expression and tone.

As far as he knew, Master rarely went to the peaks, and except for going to Tiangong Peak every month to receive the moon, he hardly interacted with anyone. If you want to talk about getting closer, there is only Master Douyuan.

But why, Master seems to be quite kind to this wooden beauty?

Obviously, I should have been moving around before, or rather quite familiar. If it weren't for that, how could you use such an obvious nickname as 'Xiao Ming'.

Looking at the master, whose smile was obviously much more affectionate than usual, Li Changan couldn't help but feel a little confused in his heart.

Everyone has a love for beauty, which is understandable. However, this matter fell on his master, and Ling An still couldn't accept it.

"Mingyue was ordered by the family teacher to come to check. ”

"Oh, hehe," Lu Laodao smiled again, waved the dust in a chic manner, and said: "This is the poor road to be idle, for the purpose of excursions with the apprentices, and nothing else." ”

Izumo nodded blankly, her movements stiff, as if someone had pressed her beautiful head. Then, he said in a tone without emotion: "Yes, Uncle Shi, Mingyue retires." ”

Bai Luan roared and burrowed back into the clouds.

Everyone has flown far away, and the master is still smiling there. Li Changan felt more and more that the old man was secret... Appreciating each other.

Even though they are all monks, age is not an issue. But as soon as he thought of the famous scene of a famous grandson's love in his previous life, Li Changan trembled, shook his head, and quickly shook off this terrible thought.

Master's affairs, as an apprentice, must not be ignored. For now, though, we'll put the matter aside.

Danxia Peak is right in front of you.

After a while, I saw that in the peak of the sky, two figures flew up.

There were two people, one left and one right, arching the [Flying Ball Sightseeing Tour] four people.

"Yo, what kind of novelty is this? ”

Then, the two of them circled the hot air balloon and let out a "Uh-huh, uh-huh, uh-huh... Ha~~ah!".

The old Dao Lu Wuxiang has always been out and about, and after looking at it for a while, he is sure that he doesn't know him. However, the Taoist robes worn by the other two looked ordinary, but they were treasure clothes that were not easy to refine. Moreover, the corner of the robe is embroidered with [Wu] and [dove], and the old Taoist has a judgment in his heart.

He smiled and said, "The two of you are the fifth senior brother and the ninth senior brother of Danxia Peak!"

The middle-aged immortal on the left, who was quite strong and middle-aged, smiled and politely greeted Lu Wuxiang.

"Oh, I don't know which peak junior brother it is?"

"Grief Peak and Lu Wuxiang have seen two senior brothers. ”

Lu Laodao coped skillfully and greeted him.

The old man on the right, with gorgeous hair and a stiff back, asked straight after a few polite words between the two, "I don't know, what is Senior Brother Lu riding?"

"Oh, this is a poor road with nothing to do, for the purpose of visiting with the disciples, and nothing else. ”

Exactly the same wording, without changing a single word.

The two on the left and right, who were also honest and unkind, surrounded the hot air balloon and looked up and down, left and right.

The old man also used a touch of immortal power to investigate carefully.

After a while, the old man was even more surprised and asked, "But there are no other immortal powers, arrays, and only two fire talismans can fly."

Fifth Senior Brother, what is the reason for this?"

Listening to the old man calling the middle-aged immortal elder a senior brother, Li Changan and Gongsun Tuo both dropped their jaws a little. You really can't judge people by their appearance, oh no, take immortals!

"It's... Xiao Jiu, you have always been the most ingenious, you can't see the reason, and we can't understand it. Tsk, hehe..."

The 'Fifth Senior Brother' laughed dryly twice, and said in a low voice embarrassedly, "Senior Brother Lu, can you tell me about the flying of this novelty and my senior brother?"

Lu Lao said but smiled silently.

It's not that he's on the shelf. Just because Chang'an had told him in advance that if he arrived at Danxia Peak, he didn't need to answer when someone asked about production. Everything, but it depends on the big apprentice to deal with it.

"Master, why don't you let the apprentice explain a thing or two to the master?" Li Changan on the side 'proposed'.

Lu Laodao nodded cooperatively according to the script he had said in advance. However, Lao Dao was inexplicably a little nervous in his heart.

The person who came was not someone else, it was the two of the nine high-ranking disciples of Ziyang Laojun, who were ranked five or nine, and in the refining process, they were all masters who could be counted.

Chang'an is indeed whimsical and ingenious, but in front of these two serious refining masters, if he says something wrong...

Lao Dao's state of mind at the moment is very much like the old father waiting outside the college entrance examination venue...

But seeing that, Li Changan generously bowed to each of the two Danxia Peak refiners, smiled tastelessly, and responded humbly and politely: "Two masters, the name of this thing is hot air balloons." The principle that it can fly without mana is ......"

So and so and so and so and

A concise overview of the floating principles of heating air, thermal expansion and contraction, and how to use the fire charm and wind direction and speed to speed up and slow down the flight speed and other spell magic effects.

When the two immortal elders of 'Five' and 'Nine' heard this, they seemed to understand but didn't seem to fully understand, they just felt that this should be the case. The two of them nodded from time to time, and from time to time they thought about it.

"Poor Dao has heard of it, Senior Brother Lu's Dan Dao attainments are profound, I didn't expect wow, Senior Brother Lu also has something unique in refining weapons!" The middle-aged male cultivator was full of praise, with a look of surprise and admiration on his face.

The old Dao Lu Wuxiang, who was hanging in his heart, felt very useful.

Of course, he was not complacent because he was praised by these two well-known refining masters. He knew that his big apprentice loved to knock and beat when he was a child, and he was tinkering with this and that.

But he never expected that he first built a big waterwheel that could wash out a spiritual stone mountain. The big ball that came out this time was actually appreciated by the two refiners who specialized in cultivating weapons.

Could it be ??!!

Lu Laodao crossed a spiritual light in his heart.

Eh, I should have thought of it a long time ago. Isn't this kid Chang'an very suitable for refining weapons?

Just thinking about it, he heard the middle-aged immortal chief ask: "Senior Brother Lu, I know a lot about the treasures and materials in the world. I can't even see what kind of treasure your ball is made of?"

"Fish..."

"Ouch!"

Lu Laodao almost blurted out, and then he heard Xiao Azi exclaim.

"Master..."Ah Zi pouted and rubbed his lower waist bone, a slightly upturned part above the root of his thigh, and was about to cry that he didn't know who had pierced him, but he was pulled behind by Li Changan.

"Master, it's not early, my sister should be hungry. ”

No matter how dull Lu Laodao was, he knew that he had just almost said what he shouldn't have said, and his sensitivity was full in an instant, and he received Li Changan's signal.

"In this way, two senior brothers, Poor Dao will first take three apprentices back to the Sorrowful Peak. Empty again, empty again. ”

As he spoke, Lu Laodao arched his hand at the two.

The two refining masters glanced at each other, and they didn't want to say anything more.

"Okay, good, junior brother, let's go. ”

"That's... Senior brother, Gu Mozi will come to visit Sorrow Peak one day, I don't know if it will disturb?"

Lu Laodao shook off the dust and said with a smile: "Don't get in the way, don't get in the way." ”

With that, the hot air balloon floated slowly and leisurely all the way back.

Good wind with strength.

Along the way, Ah Zi was still rubbing her jade buttocks, which she didn't know what she had just been pierced, and looked at Li Changan suspiciously;

Li Changan secretly gave his master a thumbs up, while Lu Laodao wiped his sweat slightly, he almost told the 'fish belly' thing just now.

In fact, even if Lu Lao Dao really said it, it doesn't matter. Anyway, after this move, as long as that Ziyang Laojun is not blind, he will definitely be able to see it.

What's more, it has already attracted the attention of the two Danxia Peak refiners.

Even if Lao Jun didn't see it in retreat, when he turned around, he would hear about the [Hot Air Balloon Tour Immortal Mountain] from the mouths of his own disciples.

It's just that retaining a little mystery can arouse the other party's greater interest.

Li Changan was also forced, and he really had no tricks.

He had already prepared the big waterwheel method of enduring the pain and sacrificing the purification of the spirit stone, but as a result, he waited for two months and had no news.

This feeling is like a beautiful woman who is ready to dedicate herself, bathing, changing, and posing, and then his uncle doesn't even look at it.

Wrong payment, wrong payment.

Are the refiners of Danxia Peak so non-gossipy? Or is it that the extremely strange behavior of frequently exchanging spirit stones is nothing to the monks at all?

I can't go and invite the old gentleman to come over by myself, point to the big waterwheel and say, "Look, big man, this is my invention." ]

Even if he doesn't want to do this, Ren Laojun is not something that a little disciple can see if he wants to.

Don't be stupid, this is tantamount to directly exposing the personal relationship between yourself and Elder Gentle, phew, personal relationship, phew...

In short, Elder Yixian's hole card must not be revealed unless it is absolutely necessary.

Therefore, Li Changan was forced to show [real technology].

As a result, there are hot air balloons that look gorgeous but are actually useless.

Returning to the Sorrowful Peak, as soon as he landed, Lu Laodao summoned Li Changan to the Danfang.

"Chang'an, do you want to go with the refining tool with Wei Si?"

Li Changan was stunned for a moment, and said in his heart that the master has opened up today, but he can see it?

"Thinking about it, you love to make some novelties when you are young, and many of them are very useful.

In this way, Wei Si went to talk to Senior Brother Dou Yuan. It shouldn't be too difficult for him to admit his personal favor and ask a Danxia Peak refiner to accept you as an apprentice and teach you the method of refining. ”

Heh, think too much. It turned out that the master didn't see through his intentions beforehand, and was purely planning for his spiritual future.

His heart warmed, and he said with a smile on his face: "Master, you are going to send Chang'an to Beifeng to apprentice." ”

Lu Laodao was stunned for a moment, patted his head, and hurriedly blamed himself: "Old confused, old confused." I don't mean that..."

didn't mean to joke, but it made the master blame himself.

Li Changan decided that he would never make such jokes with his honest master again in the future.

"Master, you can rest assured that you can make your own plans.

By the way, Master, there are two things that the disciples don't understand about the method of the Spirit Clan's butterfly transformation......"
