It's good to practice in the mountains, and time flies.

And so, a hundred days later.

Jueran Peak [Daming Hall], the morning class has just ended.

Gongsun Tuo, under the gaze of more than a dozen pairs of girl's eyes as usual, put the class notes into the cloth bag that his senior brother sewed for him, walked up to Deacon Fayun as usual, and bowed down to make a bow.

Look at that or the eyebrows are affectionate, or the autumn waves are secretly sent, or the coquettish smile... , Li Changan, who was secretly observing, sighed slightly in his heart.

This nerd really listens to him, who is a senior brother. actually established a revolutionary friendship with Liu Ya to cultivate immortals, and in addition to asking for scriptures every day, it is to learn from each other.

This is not a big deal, what makes Li Changan feel a little headache is that Xiao Azi, who is surrounded by a group of male cultivators at this time.

Since the time Linjiang City strayed into the Smoke Willow Land, Ah Zi has awakened a special skill.

'Cospree', role-playing.

And after she was officially accepted as a registered disciple by Lu Laodao, and Li Changan brought this named junior sister to the morning class, she was like a fish in the sea and brought this skill to the extreme.

Sometimes it's ignorant Lori style, sometimes it's coquettish and light mature woman style; She acted decently, and even tried unconventional types such as a bosom big sister and a gossip little long tongue.

From the hairstyle to the expression, to the dress, tone, and eyes, it simply imitates the essence of real hearing, real seeing, and real feeling.

Really. Variety show.

Due to the variety of styles, the male cultivators who are attracted by her fascinated temperament, from the middle-aged uncle to the little Zhengtai who has just entered the mountain gate for less than a year, can be said to have everything.

In fact, Ah Zi is so 'nonsense' because she is just a grass spirit.

There is a big difference between spirits and demons, beasts and other living beings.

The so-called Forgetting Worries Grass Grass Spirit is actually a wisp of innate aura between heaven and earth, which is born by the condensation of Forget Worries Grass. It's not that it means that it is a forgetful grass that has been cultivated and cultivated.

Spirits are not spirits and have no real emotions of their own.

Ah Zi just wants to learn to be a real person with knowledge, feeling, and affection through imitation.

If it weren't for knowing this, Li Changan would have thought that the innocent little Ah Zijing had been divided.

It was precisely because he understood the reason that he didn't restrain Ah Zi too much.

But now it seems that it doesn't work anymore. If it goes on like this, this girl has a tendency to develop all the way to the demon.

If you can't keep it, one day you will cause some debts and bear a bad result of marriage.

It's time to put things right and stop the bad wind.

The accessories have been built, it is better to hit the day than to hit the day, and start assembling the big guy today!

In this way, what Xiao Tuo has learned in recent months has been put to use, and Ah Zi has more 'interesting' things to do.

Performing the flying technique that had just been learned for a short time, the three of them flew towards the Sorrowful Cry Peak together, and the speed was many times faster than that of Chengfeng Jue.

As soon as she landed, Ah Zi pulled the light pink shirt and skirt on her body, and her fingers curled one side of her hair, looking well-behaved.

"Senior brother, Ah Zi will go and prepare lunch. Today, do you want to eat fried rice, steamed rice, or soup rice with fish?"

Today's share is a small jasper style. To tell you the truth, it's quite likable.

Li Changan smiled and said, "You don't have to get it, if you are really hungry later, you can eat some fruit." ”

In fact, Ah Zi himself doesn't have to eat, and Li Changan and Gongsun Tuo have also been in the valley for a while. Even if you don't eat for a long time, it doesn't have any effect on your body. It's just that every once in a while, get a few fat fish to beat their teeth.

"Oh. Ah Zi bowed slightly, and learned a lot.

The three of them walked to the bamboo house as they spoke, and Gongsun Tuo continued: "Senior brother, senior sister, Tuo has gone to practice." ”

"Ah Zi, Xiao Tuo, haven't you always been curious about what I made in the cave in the back mountain?"

As soon as Li Changan finished speaking, Ah Zi, who was obediently and skillfully following the side with small broken steps a second ago, immediately let out a happy scream, picked up his long skirt and jumped in front of Li Changan, shouting.

"What is it, what is it? What is it?"

Gongsun Tuo also looked at his senior brother with curious eyes.

Li Changan pretended to ponder, and after a few breaths, he took a deep breath as if he had made up his mind, and said, "You two are my fellow disciples, and they are also my dearest. There shouldn't be anything to hide from you, it's just that this thing is extraordinary!

It is related to the future development prospects of our Sorrow Peak, as well as the future happiness of the three of us.

Today, I have decided to entrust this extremely important matter to the two of you.

I wonder if you would like to be a part of this great cause. ”

"Yes, 11,000. Say it, say it..."

"Senior brother!" Gongsun Tuo bowed to Li Changan with an awe-inspiring face, and said sternly: "I can contribute to the Sorrowful Cry Peak, and I can't ask for it."

Everything was provoked by the senior brother, and Tuo Shen was ashamed. Although the senior brother commanded, he did not hesitate to expand his liver and brain. ”

Li Changan: .........

Do you want to be so hot-blooded.

The corners of his mouth twitched, Li Changan beckoned, and motioned for the two to follow.

............

"To the left, yes, to the left.

Stop, stop!

Okay, that's the angle......"

Three days later, on the shore of the bamboo house of the Wailing Peak, under the waterfall.

A large watermill with a diameter of about 30 zhang was perfectly completed.

Under the command of Li Changan, after Gongsun Tuo installed the last bucket, he flew back to the lake, and collapsed directly to the ground due to exhaustion.

Ah Zi on the side, also in the same shape, lying on his back by the lake. Panting, his chest heaving, heaving.

For three days in a row, he kept taking wood to build a bucket, Rao is a natural wood attribute such as Ah Zi, and he was also overused to the point that his spiritual power was empty and his physical strength was exhausted.

Li Changan clapped his hands, looking at the masterpiece in front of him, which was as big as a Ferris wheel, and felt relieved in his heart.

Sure enough, I am really suitable and talented to walk the refining tool.

Originally, it was thought that there would be errors or losses during the installation process. I have prepared some more axle wheel brackets made of black cast iron, but they are redundant at the moment.

It's all a small thing, and then you have to test whether your idea can come true.

In the middle volume of the "Four Transformations and Four Elephants Sutra", it mentions the content about the formation of spiritual veins, earth treasures, and spiritual stones.

Later, Li Changan found a more specific description in a book on the introduction of refining.

After reading it repeatedly, I had a bold idea. After a few nights of analysis and discussion with the master, Li Changan decided to give it a try.

If it is really as he has studied, this is not just a waterwheel, but a device comparable to the level of a 'magic weapon'!

According to Li Chang'an's understanding, the so-called earth treasure spiritual vein, as the name suggests, is the spiritual power that is suppressed in the depths of the earth, and through the movement of groundwater and the earth's crust, the underground spiritual power is formed to gather the ground;

It is a bit similar to mineral deposits and oil, which are not evenly distributed, and there are many and few places in different places. Like the mundane world, it is basically no spiritual power or so weak that it is about equal to nothing;

The spiritual power in the underground spiritual veins will flow periodically with the movement of underground water or the earth's crust, and some high-purity spiritual power will form translucent crystalline substances with different colors and purities in the process.

This is the formation of the spirit stone.

However, in the process of formation, some impurities will be entrapped. For example, it contains turbidity gas, mixed ore particles, etc.

Because of this, the spirit stones have grades.

Lower-grade spirit stones, mostly brownish-yellow, brown, etc., are mainly used in small formations and mechanisms with the lowest power to supply energy for low-level Dan furnaces;

Medium-grade spirit stones, with blue, blue, ochre and other colors, are used for small and medium-sized formations, fill medium-sized organs, embed in demon traps or demon traps to increase power, and provide energy for medium-level Dan furnaces;

High-grade spirit stones, light blue and white, turquoise, light purple, etc., are used for large-scale formations, mechanisms, and high-level arrays;

The best spirit stone, the output is very small, it is extreme, it is either transparent and pure colorless, or it is dark purple or simply black, and the spiritual power contained is extremely rich and abundant; it is generally only used to refine high-level magic weapons, spiritual treasures, or to supply energy for high-level formations and array disks.

In addition, only the best spirit stones can refine the Qiankun array disk.

These are only mentioned in the "Five Elements Wheel Rotation Array Disc of Refining", and because they are only introductory knowledge points to illustrate the introductory classics of refining, they are not recorded in much detail.

However, Li Changan is not in a hurry to do an in-depth understanding now, with his current scum cultivation, it is good to be able to teach himself to enter the door, and those tall array disks are clouds that cannot be touched.

Eat whatever kind of rice you want. Wishful thinking about such a thing, of course...

Still have to think about it.

Otherwise, where did the power come from to support him in these three months, every day with a sledgehammer and forging accessories;

He also built a furnace in the cave, and with his own fire root genus, he gritted his teeth and made such a big guy.

Now, he is also a man with strong martial arts and well-developed chest muscles.

After a short rest, Li Changan whistled loudly at the waterfall.

After a while, the black whirlwind with the head of the leopard, which received the 'summoning code', poked its head out from under the waterfall.

Seeing this giant beast, the leopard's eyes shrank, "What is this?"

"Watermills. Li Changan didn't even think about it.

Pour out the spirit stones in the Qiankun bag, and use the magic technique to put the spirit stones that have been divided into categories in advance into the barrel of the waterwheel.

The leopard's head jumped out of the waterfall, and its huge body landed lightly beside Li Changan, with legs eight meters long and not fake.

The leopard raised its head and paws and was about to go to the water wheel, but Li Changan stopped it in time.

"Don't move, when I'm done, I'll bother the leopard boss for your help. ”

"Help, you kid, you know how to call Lao Tzu. The leopard's head and nose breathed out, and the air wave blew into the waterwheel, turning slightly two squares.

Li Changan quickly threw the spirit stones divided into more than a dozen bags into the wooden barrel one by one. Clapping his hands, he pointed to a grouting trough on top of the waterfall and waterwheel, and said:

"Thank you, Boss Lao, thank you! If it happens this time, you want to... You can eat whatever you want. ”

It's outrageous to want, eat and drink, he can barely afford it.

The leopard's head snorted again, its nose exhaled, it roared and laughed twice, and with a flick of its tail, it intercepted a section of the waterfall and led it to the top of the waterwheel.

I saw that the huge waterwheel with a cast-iron and mixed wood structure turned up automatically.

What kind of novelty is this?!

The leopard's head looked left and right, pondered for a while, and then asked, "Huh, what kind of spell did you kid cast, we can't see a way to see it." ”

Gongsun Tuo and Ah Zi had also gotten up a long time ago, and seeing this situation, it was also a novelty. I flew around the waterwheel at a faster and faster speed a few times, and I also looked straight.

"Senior brother, this is... Five Elements Magic?"

"No, it's still the Illusion. Are you right, brother~~"

Li Changan glanced at Ah Zi amusedly. I have already figured it out, there is nothing to do with Xiao Chang'an, and there is something to do with senior brothers.

Oh, female... Spirit.

"According to the silk, it is not what kind of magic it is, but it is the result of skill. Wonderful!"

Everyone's attention was attracted by the big waterwheel that automatically turned non-stop, and only then did they find that Lu Lao Dao, who was intoxicated with the great cause of Dan Dao, had already flown into the air behind them at some point.

"Master!"

Three times in unison, Lu Laodao looked at the three obedient disciples, and nodded with a smile in his eyes.

"Xiao Wuxiang, we don't understand what is ingenious or not. This technique certainly worked, but we couldn't see it through for a while. ”

"Snort," Lu Laodao waved the dust and said proudly: "No matter how high your ability is, you are still a fierce beast."

This man's power is not just magic.

Forget it, I told you that you don't understand. This ingenuity is also very simple, that is, with the power of water potential, the wheel is turned. ”

The leopard's head and nose puffed out, and its tail raised demonstratively. Lu Laodao didn't care about it, flew around the waterwheel, and pondered carefully.

The leopard head and the master hated each other as soon as they met, and the way they got along with each other every day, Li Changan had long been surprised.

Gongsun Tuo and Ah Zi saw the master and the leopard head meet for the first time, and they were quite curious about the smell of gunpowder between the two.

"Oh... Well... Ah, that's what happened... Tsk, not bad, not bad..."

Before Li Changan made this object, he consulted him with the drawings.

Although he didn't understand what was depicted in the picture at that time, now that the two are combined, Lu Laodao completely understands.

My apprentice's head is really good, and he has a pair of wonderful hands, hehe...

Lu Laodao flew to Li Changan's side, and the two of them said a few more words, but the two people and one beast on the side didn't understand half of the sentence.

What 'washing', 'peeling', 'non-destructive', 'figurative'... What the hell are you talking about?

After a heated discussion between the master and apprentice, Lu Laodao laughed heartily.

"Wonderful, wonderful!

Low-grade to medium-grade, up to seven days, can confirm your curiosity.

For silk, I'm looking forward to it......"
