The seven magic swords slowly transformed in Wu Kun's hands, and after a few days, each sword was almost as strong as a true god weapon when it was taken out alone, but it was limited to the material itself, these magic swords could not be upgraded, but the seven swords together, the momentum would definitely crush most of the true god treasures!

Wu Kun looked at the seven magic swords in his hand that had reached their peak, and thought that there were no sword-like treasures on his body, the only thing he had was a true god-level treasure, Ying Long Bow, but there were no arrows.

"It's good to grind a few arrows right now. ”

As for the materials, Wu Kun's first thought was the bones of the demon beasts, the bones of the god-level demon beasts in the ring were extremely hard, and they were not inferior to the divine gold in terms of hardness.

He took out a few hind leg bones of the demon beast and began to polish them, the hind leg bones were one of the hardest bones in the demon beast's body, and the length was long enough, just enough to be used to hone the magic arrow.

"Yo, what are you doing here? I've found some good places, why don't you go and walk around?"

Yin Shiyin, who had already turned around most of the time in the Great Emperor's refining place, came back and said to Wu Kun.

"Wait, wait until I've sharpened these four arrows. ”

"How long does that have to take?" Yin Shiyin said impatiently.

"Haven't you heard the story of an iron pestle sharpened into a needle?"

Yin Shiyin shook her head, and she thought to herself: "It's not difficult to grind an iron pestle into a needle? Isn't iron the easiest metal to polish? I can also melt it into a needle with my spiritual power." ”

However, Wu Kun almost blurted it out, in fact, he couldn't remember what it meant.

Wu Kun was still continuing, and the young man was also repeating the action of sharpening the knife here, Wu Kun was secretly surprised in his heart, the quality of that knife was even higher than he expected! Wu Kun alone was here for a few days to hone the sharpness of a god-king-level treasure to an excellent level, and that young man had been here for more than just a few days, his appearance was obviously that he had been here for a long time, so that knife was at least the god-king level!

Yin Shiyin, who watched Wu Kun sharpen her arrows, was obviously bored to a certain extent, and in her idleness, she had a whim, the weapon of the bone golem was their claw, could the claw be polished here?

Thinking like this, Yin Shiyin immediately released the bone dragon, and then ordered him to grind the two extremely sharp steel claws in front of him on the purple spirit sand.

Not to mention, this really has a great effect, after hundreds of thousands of polishing, the sharp energy emanating from the pair of steel claws is really sharp to a degree, and the shiny claws make Wu Kun feel a palpitation when he sees it.

When the bone dragon appeared, the young man who was originally calmly sharpening his knife on the side was not calm in an instant, his eyes narrowed slightly and looked at Wu Kun and the bone dragon of the Supreme Realm, on the surface, there was no wave, but in his heart he was extremely shocked, these two people who seemed to be obviously from the Nether Realm actually carried such a powerful puppet with them!

After a brief shock, the young man lowered his head again and sharpened his knife, although the supreme-level puppet was terrifying, he did not provoke Wu Kun and the two, and if he really wanted to fight, even if he couldn't beat him, it would be impossible for a supreme-level puppet to keep him. The geniuses of the upper realm can't measure their strength by their cultivation, they come from the big clans, and all kinds of hole cards emerge in endlessly.

Wu Kun and the two put away the puppet, like someone who has nothing to do, this young man has not moved, they have always lived in peace like this, the young man looked up when Wu Kun and the two left here, there was no emotion in his eyes, just a simple glance.

"Brother Tianhuang, there are several training places ahead, you have to be in a hurry to sharpen some arrows here. ”

"Oh, tell me, what's so special about those places?"

"You'll know when you go. ”

These training places are not very far apart, next to the purple spirit sand mountain is a cold spring, the temperature of the cold spring is extremely low, but it does not form ice, the cold spring is crystal clear, and there are countless remnants of soldiers deposited at the bottom, these are the remains of the spirit treasure that has failed to be refined, if the spirit treasure wants to obtain the ultimate ice cold attribute, it is a quick way to use this cold spring to quench.

Wu Kun had a whim, if he put the sharpened arrow into the cold spring and tempered it, would it give the arrow the attribute of ice? Wu Kun also belongs to the kind of person who does what he says.

The moment the bone arrow soaked into the cold spring, the cold breath filled the entire arrow at an extremely fast speed, and the arrow that was originally slightly whitish instantly turned into light blue, and the blue gradually deepened with the time that the arrow was immersed in the cold spring, and finally broke into a few sections, fell into the bottom of the cold spring, and became a part of the broken sword at the bottom.

Seeing that the results of his hard work for a long time were gone, Wu Kun was extremely heartbroken, he didn't expect that the bones of the god-level demon beast would not be able to hold up for half a minute!

The time of cold quenching is directly proportional to the extreme cold power that the treasure can have after the quenching, if the treasure is strong enough, the longer it can withstand the quenching, the stronger the power after quenching. However, the stronger the requirements for the Noble Phantasm itself, the God-level Noble Phantasm can only last for half a minute.

Wu Kun took out the second arrow and soaked it in the cold spring for twenty seconds before taking it out, but after a while, the arrow broke again! Wu Kun overestimated the bearing capacity of the god-level treasure bone, and after soaking the arrow, the remaining cold spring on it could erode the arrow.

"......" Wu Kun was extremely speechless in his heart, all this was completely different from what he imagined! As a result, he lost an arrow again in vain, Wu Kun's flesh hurt, the bones of the god-level demon beasts were already few, and he had to take the hind leg bones, he couldn't afford to consume them!

Wu Kun trembled and took out the third arrow, he had to try it anyway, after all, he had failed twice, if he didn't succeed once, then he really lost a lot.

"Are you wasting resources?" Yin Shiyin scoffed.

The corners of Wu Kun's mouth twitched and said, "Don't affect me, the last one, I'll leave if I fail!"

"Don't you still have one?"

Wu Kun ignored Yin Shiyin, and for the sake of conservatism, the arrow was picked up by Wu Kun again the moment he put it down, however, it didn't seem to have any effect......

Wu Kun was ruthless, put the arrow in the cold spring, counted five and then quickly took it out, only to see the cold and the sharp energy of the arrow slowly merged, the whole arrow slowly became transparent, the arrow flashed with cold light, the sharp breath was revealed, the arrow body was transparent, dragging a long white cold air!

This arrow has been greatly strengthened! Wu Kun took out the Ying Long Bow, put the cold arrow on it, and pulled it out towards the void with a curved bow, the extremely cold momentum seemed to freeze the air! That unbreakable sharp aura made the cold arrow unstoppable! Read the latest chapter of the "Reincarnation 20,000 Years Claw Book House" for free for the first time.
