"This is the style I saw from a book of the Heavenly Outer Dao, and I think it's quite interesting...... And also reserved for the future energy furnace interface......"

Fang Xi replied with a smile.

Because of the previous 'Gate of Ten Thousand Worlds', the Kyushu border is really connected to many worlds.

The Taoist books that have been handed down from those worlds are all called the 'Heavenly Outer Dao Books', and the most famous of them is naturally the Pure Yang Dao Book that records the magic weapon of the 'Sun True Fire Cover'.

In addition, there are some strange martial arts techniques, which are used by those ordinary people, and with the transformation of the prosthetic body, different functions are developed, and some can even match the Qi refining and foundation building monks, which is quite good.

Fang Xi used the Tianwai Dao Book as an excuse, and Huo Yunzi didn't ask too much.

After all, this is the monk's own fate, and the monk is already a person, and he can have a certain little secret.

Even in Fangxian University, there are many college students who do not practice the exercises in the university library, but their own family exercises.

"Okay, now that you're sure it's okay, let's get started...... I'll only promise to borrow it from you once, and if something goes wrong, there's no chance of backtracking. ”

Huo Yunzi uploaded the USB flash drive information: "That's right...... Xiao Zhang, what's the name of your flying sword? ”

"Qinghe Sword!"

Fang Xi replied without hesitation, a hint of remembrance flashed in his eyes.

Although he gave the refining map of the Demon Slaying Sword, he said that this was the Qinghe Sword, and it was naturally the Qinghe Sword!

'Counting, this is already the fourth generation of Qinghe Sword, right? ’

This fourth-generation Qinghe Sword is based on the 'Demon Slaying Sword' in the 'Three Treasures of Demon Slayer', and added to the refining process of the Kyushu Realm, preparing to upgrade it to a 'flying rice' level magic weapon that is even finer than 'nano'!

As for the grooves on it? Naturally, it is prepared for the Feimi robot, after all, the fourth-generation Qinghe Sword is for the deity, and there is no place in the Southern Wilderness Immortal Cultivation Realm to charge the Feimi robot.

If it can't be charged, then this flying sword can only be used as an ordinary flying sword magic weapon, which is not very powerful.

Fang Xi was still very interested in the last time Jiannan Zhenjun's golden flying sword that could divide 1.296 billion thin needles.

As for the energy problem in the groove, Fang Xi had already thought about it, he could use a metallic top-grade spirit stone!

If Huo Yunzi knew that Fang Xi was going to use the strategic level materials that were rare to see in the Kyushu Realm Yuan Ying Zhenjun to urge the Qinghe Sword, he was afraid that he would have the heart to strangle him.

What a tyrannical thing!

It's outrageous!

However, as far as Fang Xi's turtle is concerned, if he can simply build the 'Qinghe Sword' because of his ugliness, it is already a success!

"Open!"

At this time, Huoyunzi Zhenjun didn't know anything about it, he just silently pinched the magic trick, and a primordial infant-level mana was injected into the gossip furnace in front of him.

One after another, the array lines lit up, and countless streamers converged from all directions, and inside the Bagua Furnace, a sword tip wrapped in white light had emerged, followed by the sword body and the hilt of the sword......

The main focus of the femtomi printer is the word "fast"!

In the Kyushu realm, things that take years and decades to refine a magic weapon like Gu Xiu are long gone.

"Okay, Xiao Zhang, I'll take the test, what are these formations called in this formation?"

Seeing Fang Xi's interested expression, Huo Yunzi couldn't help but feel a little considerate.

"I can only recognize a few of them, such as this formation, which is the 'Three-Element Combination Array'...... There is also this formation, which seems to be a variant of the 'Two-Phase Void Array'...... There is also this one, which should come from the 'Subspace Transformation Array'......"

Fang Xi only said a few places, which was a lot of clumsiness.

Huo Yunzi heard this, but he was very sorry: "Huh? Your kid's formation talent is good, the formation is good, and the refining weapon should also be fine...... I shouldn't have changed my department to do some research on the theory of vitality, are you interested in studying for my PhD? ”

"This ...... The younger generation also needs to think about it. ”

Fang Xi replied with a wry smile, and then saw the gossip furnace roaring, and a blue light flew out.

He stretched out his hand and made a move, and a flying sword that was three feet long, two fingers wide, and covered in blue, like a long cyan leaf, fell into his hand.

——Four generations of Qinghe Sword!

'This sword is in full form, when it has the power of the spirit treasure, when it is full of the blood of the demon clan in the future, the power can still rise!' ’

Fang Xi stroked the blade of the sword, a look of satisfaction appeared on his face, and he took his leave.

He came this time, refining magic weapons can only be regarded as an excuse.

The main thing is to make an alibi.

After all, now that Tianfeng Cave is over there, it should be turned upside down, right?

But along the way, many campus monitors can prove that Zhang Huohua has been at Fangxian University, and Huo Yunzi, the big guy, testified!

'Of course, this is only the worst-case scenario......

At best, there is no doubt at all...... But you can't underestimate the big data screening of Fang Immortal Dao Palace......

'In the next period of time, let's take a good time, maybe we can take out the 'Demon Qi Analysis Atlas'? Increase your own value? ’

Fang Xi, who returned to the cave mansion, sent the four generations of Qinghe Swords to the Southern Wilderness Immortal Cultivation Realm, thinking to himself.

The paper he put forward before only pointed out a direction that could save many detours.

And if you can come up with the 'Demon Qi Particle Atlas', it will be another big step forward!

If he can make such a major research achievement, at least the Genki Research Institute will do its best to protect him, right?

……

The Southern Wilderness cultivates the immortal realm.

Emerald Isle.

Fang Xi was holding the fourth-generation Qinghe sword, and there was a slight nostalgia in his expression.

Qinghe was named by him to commemorate the experience of Qingzhu Mountain when he was weak, and what he wanted was the spirit of fighting for his life with the sky.

The mana of the Kurong Jue gushed out, and this sword was easily refined.

Then, Fang Xi pointed casually.

The Qinghe sword turned into a cyan streamer, and the sword light was like a dragon, and it suddenly rushed straight to the nine heavens!

The clouds in the sky are all dissipated under this sword!

This kind of swordsmanship made Zheng Shan and the other monks stunned.

"Well, at this time, the power of the fourth-generation Qinghe Sword is equivalent to the top-level magic weapon that has been cultivated for many years, and the sword qi is incomparably sharp, which is enough to compete with the Ten Thousand Soul Banners of the year......

As soon as Fang Xi's sword trick was collected, the sword light in the sky rolled down, condensing into a long sword like a leaf, and he couldn't help but be very satisfied with it.

The refining methods of the Kyushu realm are really very strong!

And he returned to the refining room, and a magic trick was played.

On the hilt of the fourth-generation Qinghe sword, a groove immediately appeared.

Fang Xi slapped the mountain and sea pearls, and a golden top-grade spirit stone flew out and fell into the groove.

Buzzing!

After closing the hilt of the sword and entering the magic trick, golden formations appeared on the sword body, and it was the best spirit stone that consumed the spiritual energy, and began to charge countless flying rice robots!

"This sword is usually sleeping in the Feimi robot, it's just a dead thing, and now it's really activated......

As for the Shadow Moon Sect Master?

This person is a disguised identity, and it is impossible to expose Yuanying's cultivation, so there are not many treasures on his body, and he is not put in Fang Xi's eyes.

At least this person doesn't have this network resource, so he can go to Fang Xian University's Flying Rice Research Institute and let Huoyunzi Zhenjun refine a Flying Rice Magic Weapon for him!

Fang Xi groaned, took out the modeling diagram he had designed before, and felt out a few pieces of fourth-order ore, and a wisp of cyan baby fire erupted.

His previous blueprints had been retained, and now he could also refine many fourth-order ores, and even the bones and bloodlines of the demon clan, in order to increase the strength of this flying sword based on the Demon Slashing Sword!

A few months later......

Over the Emerald Isle.

Fang Xi stood with his hands in his hands, and a cyan long sword was suspended by his side.

"Go!"

As soon as his mind moved, the Qinghe Sword flew out in an instant.

Then......

It cracked directly in mid-air, turning into countless blue lights.

A stream of blue light flew and moved, suddenly exploded, and turned into a sky of cyan silk.

Fang Xi's expression moved, and he raised his hand.

A third-order giant tortoise puppet was released, and the turtle shell opened, and a cannon barrel emerged.

Bang!

A pillar of crimson light swept over the green silk, but the green silk did not change in the slightest, and then swept past the giant tortoise, as if it had 'penetrated' into the past......

Then......

The giant tortoise puppet froze, and was suddenly split in two from the middle......

"Femtomi is too small to easily penetrate anything substantial...... It can also be seen as the characteristics of 'nothing is not cut' and 'the sword body is difficult to hurt'......"

Fang Xi waved again, and countless green silks gathered, seeping into from all over his body, and recombining into the appearance of the 'Qinghe Sword' in the dantian.

"This kind of infiltration is very vicious, it should be able to attach to the mana and meridians of immortal cultivators and even demon cultivators, all the way to the dantian and then explode......"

Fang Xi carefully experienced the ability of the four generations of Qinghe Sword: "If the immortal cultivator is not knowledgeable enough, it is easy to regard my swordsmanship as a peerless sword cultivation of 'refining the sword into silk'...... That will inevitably lead to a big loss. ”

The sword of sword cultivation pays attention to breaking ten thousand laws with one sword, and refining the sword into silk is also an extremely high and profound kendo realm.

I'm afraid that only the sword cultivation of the Yuan Infant level can be able to comprehend one or two points.

But now Fang Xi can easily do it with a sword weapon!

"As for the disadvantages...... It is probably that after the top-grade spirit stone has exhausted its spiritual power, it still needs to be slowly recharged...... Once you get caught up in a protracted battle that takes a long time, you won't be able to use the ultimate move of refining swords into silk......"

If you want to perform all kinds of sassy operations, you must charge the Feimi robot, and the best spirit stones may be a little insufficient.

"Other than that, there aren't too many drawbacks...... This fourth-generation Qinghe sword is only destined to shine in this demon clan invasion......"

"Although, it's not what I wanted......"

If there is a choice, Fang Xi will definitely hope that his wife will plant trees and cultivate immortals all the way in peace, and then cultivate without disasters and calamities to the consummation of the gods, and then soar to the ......

How...... There are always many injustices in the world.

Not to mention the promise with the Heavenly Jealous Demon Lord, even if it is the Heavenly Demon Qi, it is worth Fang Xi's journey.

"I am willing to use the sword of Qinghe in my hand to smooth out all the unevenness on the road!"

This is also the oath that Fang Xi silently made in his heart when he got the Qinghe Sword!

No matter how difficult the road is, he has to climb the ladder and ascend from a mortal to an immortal step by step!
