Subsequently, it was Lin Fei'er's turn to be on duty, Xu Zhuo went to rest, although Xu Zhuo had been cultivating for a long time, but because of taking the Blood Flame Crystal, he was not half tired, but energetic, and the reason why he obediently went to rest was because it was too embarrassing. Or use the excuse of rest, fake sleep, to alleviate this embarrassing atmosphere.

However, Xu Zhuo didn't rest for long, and then he got up to practice again, this time he was farther away from Lin Fei'er, about a few dozen meters away from her, entered a mine cave with a relatively large space around the corner, and then waved his hand to arrange a defensive prohibition within a radius of more than ten meters around him, lest something suddenly break in and interrupt his sword refining.

But the sound insulation effect is not set, mainly because I am afraid that if something happens, Lin Fei'er calls him outside, and he can't hear it, it will be a big thing.

"This guy, what the hell is going on?" Lin Fei'er was very curious, and wanted to peek, but she was afraid to see Xu Zhuo's smooth body again, in her eyes, Xu Zhuo's figure was really quite good, big 'pectoral' muscles, like chocolate-like distinct and high bulging eight-pack abs, ape arms and bee waist, legs are also very thick, strong and powerful, revealing a particularly charming masculine beauty, dressed thin, stripped and covered in tendon meat, but, there are a few places that are particularly disgusting, "ugly" , Lin Fei'er's heartbeat will suddenly speed up after watching it, she is very shy, she feels disgusting and doesn't want to watch it, but she can't help but want to watch it, that feeling is very strange and contradictory.

Then, she saw that Xu Zhuo took out the body of the eighth-order alien beast Four-winged Bat King from the space ring, and sacrificed a blood-like fluttering flame to burn it, and suddenly, Lin Fei'er was not interested.

"Huh~, it's disgusting, burning animal corpses, it's really perverted! That stinks, he can't bear it!" Lin Fei'er pursed her lips and hid a little farther away, just closely monitoring the movements of the iron-winged bats in the distance, and at the same time preventing other disciples of the Dry Demon Sect from accidentally breaking in.

Xu Zhuo devoted himself wholeheartedly, but he didn't smell the stench at all, because the blood inflammation was very powerful, the temperature was very high, and it was almost a cup of tea, and the body of the huge eighth-order iron-winged bat king was smelted, and all the impurities turned into black ashes and fell to the ground, only a white liquid-like substance floated in the air, continuing to burn.

He was using the corpse of this eighth-order Iron Winged Bat King to practice, and he had previously obtained a unique refining method from the Dry Demon Sect, which was to smelt the bones of alien beasts and practice the bone sword.

The bone sword used before was snatched from the hands of the disciples of the Dry Demon Sect, and the grade was not high, but it was not low, although one bite was particularly good, but Xu Zhuo estimated that the materials used should not be as good as this eighth-order beast, and if he tried to refine it himself, he could also explore the refining technique by the way. Yiduo doesn't press down.

The raging blood inflammation was triggered, first it was violently smelted by martial fire, and then it was turned to a simmer and slowly roasted, removing the impurities inside little by little, Xu Zhuo had wise eyes, and it was quite convenient to observe the remaining impurities inside, when all the impurities were removed, the milky white liquid became clear and flawless, as if the jade had melted.

After about a few hours, the rough blank of the bone sword was formed, and then, Xu Zhuo began to engrave various inscriptions, using the bone sword as the carrier, using the true yuan and spiritual power as the carving knife, and inscribed various inscriptions inside and outside the bone sword, among them, the flying inscription is essential, otherwise, this bone sword will not be able to fly with the sword, and the speed will not increase when killing the enemy.

These inscriptions are the results of the research of the previous sages, and once the depiction is successful, it can hook the power of heaven and earth, and the mystery of the end is very subtle. When inscribed the inscription, it is necessary to be quite careful and serious, if there is the slightest mistake or omission, it will lead to unsuccessful engraving and the inscription will be ineffective.

In addition, there are some inscriptions with special attributes, such as bloodthirsty inscriptions, armor-piercing inscriptions, and variety-changing inscriptions, etc., Xu Zhuohui's inscriptions are not many, but they are also enough for refining flying swords.

The Variety Inscription is a very interesting inscription, the only function is to make this flying sword ever-changing, it can be turned into a sword pill, which is easy to store at ordinary times, and it can also be turned into a sword wire with the thickness of a hair, a variable double-edged sword, a variable single-edged sword, and it can also be turned into a giant knife, but Xu Zhuolian is a sword, if it is forcibly turned into a knife, it is not impossible, but the power will be greatly reduced, and it is not cost-effective. Moreover, Xu Zhuo's sword technique has not been practiced much, but it is a sword technique, and he has learned a lot of advanced ancient swordsmanship from the Lijiang Sword School.

Xu Zhuo was so busy that he was sweating profusely, and he didn't know how long it took, the bone sword was gradually about to be completed, and there was a cold air from far away from the sword.

"Oh no, Xu Zhuo, the iron-winged bats are gathering here again, and it is estimated that the space node is about to open!" In the distance, Lin Fei'er's scream came, in fact, she had already found that the space began to fluctuate, and she would open the space-time channel at any time, but Xu Zhuo was busy refining the sword and was engrossed, Lin Fei'er was not good at disturbing him, but now, the iron-winged bats swept in, and the spatial fluctuations suddenly became more intense, and it was estimated that it was about to be opened, Lin Fei'er had no choice but to scream and remind Xu Zhuo.

Fortunately, Xu Zhuo's bone sword was nearing the end, he made a trick and made the final attack on the bone sword, in an instant, the chill surged, and it was fierce, Xu Zhuo was happy, the quality of this bone sword was quite high, and it exceeded the original best bone sword in his hand. Moreover, this was the result of his first attempt at refining!

Not only did it not fail, but it was quite successful. In fact, what Xu Zhuo didn't know was that when others refine their weapons, it is often good to succeed once or twice out of ten, and nine times out of ten they are failures, and once they fail, the materials they have sacrificed will be scrapped and cannot be used again in the future.

Mainly because Xu Zhuo has the eyes of wisdom to deduce, and the various flaws in the process of refining the weapon, and with the eyes of wisdom, his IQ is simply off the charts, surpassing many cultivators, not to mention ordinary people. I'm afraid that Einstein's IQ is less than 1/10,000 of his.

As soon as Xu Zhuo came out, the iron-winged bats in the distance roared, like a devil rushing out of hell, Lin Fei'er ran fast in front, and behind, the wings of the iron-winged bats fluttered and rattled, chasing after them in the air. There were even a few iron-winged bats whose claws were about to catch Lin Fei'er. But Lin Fei'er didn't dare to stop, as long as she stopped to kill one or two iron-winged bats, she would be dragged back, and the other iron-winged bats would rush up and drown her with their claws and fangs.

"Snort~"

Xu Zhuo took out his sword, and saw that the huge sword light was like a waterfall in the sky, sweeping away towards the iron-winged bats, and the momentum was magnificent. In the blink of an eye, seventy or eighty iron-winged bats screamed and fell.

The power is amazing!

Lin Fei'er was so stunned that she even forgot to run away.

"Why is it so powerful?" Lin Fei'er muttered.

Xu Zhuo's figure flashed, like a ghost, the newly refined bone sword exerted its power, every time it was split, it was a sword that pierced the sun, if Changhong passed through the sky, he could kill seventy or eighty iron-winged bats with one sword, just a few swords, hundreds of iron-winged bats fell to the ground, and the corpses temporarily blocked the mine.

But that's fine, the iron-winged bats behind can't fly, and they start to clean the corpses of their companions with their claws and carry them behind. This gave Xu Zhuo and Lin Fei'er time to catch their breath.

Although Xu Zhuo was powerful just now, the true yuan consumed by each sword was too large, if there were a few more swords, he was afraid that he would lose his strength and die, taking advantage of this opportunity, Xu Zhuo hurriedly swallowed the pill, held the spirit stone in his hand, and cultivated, and could recover a little true yuan is a little.

The space fluctuated violently, and the naked eye could see that the space was drumming endlessly, as if boiling water, and finally, with a "boom~", a circular space-time channel with a diameter of two or three meters opened. At the moment of opening, all the hard rocks around the space-time passage turned into nothingness, and the power of the space was amazing.

If a person stands on the edge at the time of opening, even a powerful monk will be annihilated and turned into nothingness.

"It's finally time to go home!"

In the distance, Xu Zhuo and Lin Fei'er looked at this scene and breathed a sigh of relief.
