In the middle of the Qiankun Ding, Qin Duan stood on the sea of pure yang fire. In front of Qin Dui, there were three artifacts floating, from left to right were the Dragon Slaying Sword, the Snow God Bow, the Dragon God Whip, and a piece of the Divine Stone that Qin Duan got from the space wormhole.

"Qin Dui, these three artifacts and this piece of divine stone can refine a half-grade holy weapon. However, I am only fifty percent sure that I can refine it, and it is up to you whether you need to refine it or not."

On Qin Dui's shoulder, the bone dragon suddenly said to Qin Dui.

Qin Duan had seen the power of the Holy Artifact Heaven Turning Seal with his own eyes in the Elders' House that day, and he was yearning for this holy weapon at this time. Immediately, he said:

"Lian!"

Seeing that Qin Dui had made up his mind, the bone dragon suddenly flew out from Qin Dui's shoulder. Immediately, it transformed into a huge dragon shape and floated above the sea of pure yang fire!

The bone dragon immediately shouted, and at this time, a large number of demonic beast cores spewed out from the bone dragon's mouth!

These demon cores were all soaked in the sea of pure yang fire, and they were burned by the sea of pure yang fire!

These demon cores, Qin Duan looked at them at a glance and found that the level was very high! they were all the demon cores of those demon beasts and rare demon beasts!

One by one, the demon cores were burned in the sea of pure yang fire, and a crisp blasting sound was also heard, and from above the sea of pure yang fire, cyan mist immediately floated out!

These cyan mist not only contain the aura of various attributes, but also contain countless violent energies at the same time!

Then, the bone dragon gently opened its mouth and sucked in these cyan mist in one gulp! After inhaling these cyan mist in one gulp, the bone dragon immediately sprayed at the three artifacts and a divine stone in front of him!

These cyan mist acted on the three artifacts, but they did not repel those artifacts, but stuck tightly on the three artifacts!

The temperature of that red flame flame was extremely high, and the flame in the center was white, much higher than the flame in the center of the earth in the pure yang fire sea! As soon as the red flame sprayed on the three artifacts, it immediately surrounded those three artifacts and carried out incineration and sacrifice!

Then, the bone dragon continued the same action just now!

Sacrificing the holy weapon is not such a simple matter, Qin Duan saw that it would be impossible for the bone dragon to complete this important task for a while, so he immediately sat down cross-legged, ready to cultivate in this sea of pure yang fire!

Qin Duan won the first place in the Demon Slayer Martial Arts this time, and also got a Heaven and Earth Longevity Pill. This Heaven and Earth Longevity Pill is extremely pure, it is the best of the pills, and it can help cultivators improve their cultivation to a realm!

This Heaven and Earth Longevity Pill is extremely precious, and it has a great function for the improvement of the realm of cultivators, and Qin Duan wants to wait until he hits the Tianyuan realm before taking this Heaven and Earth Longevity Pill!

Qin Duan sat cross-legged on top of the sea of pure yang fire!

The temperature of the Pure Yang Fire Sea was very high, and the buoyancy was very high, Qin Duan sat on top of the Pure Yang Fire Sea, and bursts of scorching breath gushed out, burning Qin Dui's body!

And in the sea of pure yang fire, the Lingchuan holy water was also secretly surging, and the extremely yin and cold qi also acted on Qin Duan's body!

Qin Ducai took out a six-pin pill in his arms, and after taking it, he began to digest this pill immediately!

And around Qin Dui's body, cyan mist also gushed out, enveloping Qin Dui's entire body in the middle! And in the cyan mist, beads of sweat poured out of Qin Duan's delicate face, and his little face was tense, obviously he had entered a state of cultivation!

Time ticks by!

In the sea of pure yang fire, Qin Duan maintained a calm posture and cultivated there silently! In the blink of an eye, seven days and seven nights passed like this!

And in the course of seven days, there were three slight explosions in Qin Dui's body! These were all signs of the growth of Qin Dui's internal cultivation!

Seven days later, Qin Dui opened his eyes, and at this time, the light in his eyes was even better than before! Moreover, there were bursts of strange luster flickering on the skin of Qin Dui's body!

Qin Duan could feel that his strength was already at the peak of the Human Venerable Realm, and he was only one step away from entering the Human Saint Realm!

Qin Duan stood up, and at this time, in the Pure Yang Fire Sea, the Bone Dragon's task of refining the Half-Grade Holy Weapon had been completed! In the Pure Yang Fire Sea, the Bone Dragon's huge body was lying on it, gasping for breath there!

And above the sea of pure yang fire, there was a black big knife suspended on it!

This black big knife is very long, more than ten meters long, the whole body is blue and black, and the whole body is covered with Dao scars, these are all left by the bone dragon when he was refining the half-grade holy weapon!

Although the appearance of this black broadsword was not half unusual, as soon as Qin Duan approached the black broadsword, he found that there was an invisible pressure pressing towards him!

Qin Duan wanted to walk into the black broadsword, but found that his body seemed to be instinctively repelled by the black broadsword, and was stubbornly resisted ten steps away!

Seeing that this black broadsword actually dared to resist him, Qin Dui's competitive heart was immediately aroused!

Before Qin Duan could take a step forward, the resistance of the black broadsword doubled! When he stepped out three or four times, Qin Duan only felt that in front of him, it was not the void qi that was blocking him, but the rows of incomparably tall mountains! Qin Duan only felt that there was a tremendous pressure rushing towards him, and as long as he didn't pay attention, this pressure would immediately knock him out!

Although the coercion of this black broadsword was great, it was not enough to convince Qin Dui! Qin Dui let out a low roar, and his whole body was full of vitality, and he took a big step towards the black broadsword again!

Qin Dui took this step, and the majestic vitality in the person's own body pressed towards the black big knife, wanting to suppress the black big knife with the vitality in his body!

But unexpectedly, with an increase in Qin Duan's vitality, the power of the black broadsword increased tenfold!

A surging and vast momentum surged out from the black broadsword, and immediately rushed towards Qin Dui! Soon, Qin Dui was completely repelled by several steps!

"What a powerful coercion!"

After Qin Duan stood firm, he couldn't help but gasp as he looked at the black big knife in front of him. At first, Qin Duan looked at the ordinary appearance of the black broadsword, and he was a little unimpressed, but as soon as he came into contact with it this time, he knew that the great power of this black broadsword could come!

The more powerful this black broadsword is, the more powerful it is, the more peerless the black broadsword is! This is even more of a good thing for Qin Duan!

"This black big knife is the emperor of the sword!

At this moment, the Taixu Ancient Dragon, who was resting in the sea of pure yang fire, spoke, and immediately said to Qin Duan.

"Hallows are different from artifacts, and Hallows generally have instrumental spirits. Unlike artifacts, which can only be used with a blood sacrifice. ”

"Machine spirits?"

Hearing the bone dragon's words, Qin Duan couldn't help frowning. Immediately:

"What is a machine spirit?"

"The so-called instrument spirit refers to the spiritual consciousness of the holy weapon. The Hallows also have thoughts, preferences, and preferences just like people. You must not forcibly subdue him, or it will cause him to resist. There is a divine stone here, like a divine stone, immortal energy, and the like, all of which are liked by holy weapons. You can take it and let this black knife increase your favoritism."

After the bone dragon finished speaking, he suddenly opened his mouth, and immediately spit out a divine stone towards Qin Duan. And Qin Duan immediately stretched out his hand and caught the divine stone.

Holding the divine stone in his hand, Qin Duan slowly walked towards the black big sword. And at this time, sensing the divine stone in Qin Dui's hand, the black big knife actually fell over the tip of the knife and aimed at Qin Dui, as if he was looking at Qin Dui!

Qin Dui slowly walked into the black broadsword, and at this time, the resistance power that came from the black broadsword was obviously much less! Moreover, the closer Qin Dui got to the black broadsword, the more Qin Dui felt that there seemed to be a very light and faint divine sense fluctuation from the black broadsword!

Qin Duan placed the Divine Stone in front of the black big sword, and from within the black big sword, a burst of cyan smoke immediately gushed out, enveloping that piece of divine sense!

Soon, that piece of divine consciousness was sucked into the blade of the knife by the black big knife! After absorbing that piece of divine stone, the black big knife also had a much better attitude towards Qin Dui, and suddenly, the whole body came over and gently rubbed the blade on Qin Dui's cheek, like a coquettish child!

Although the cold aura emanating from the black big knife made Qin Duan shiver all over his body, being able to win the favor of this half-grade holy weapon also made Qin Duan overjoyed!

Qin Duan held back the ecstatic expression in his body, slowly stretched out his hand, and touched the handle of this black big knife!

And this black broadsword did not resist at all, and the whole blade was very calm and serene!

After grasping the handle of the black broadsword with one hand, Qin Duan felt that within this black broadsword, there seemed to be an incomparably vast Qiankun world!

At this time, Qin Duan truly understood the supreme power of this half-grade holy weapon!

"Good knife! It is simply the best of the knife, the king of the knife!"

Feeling the domineering spirit contained in this black broadsword, Qin Duan suddenly couldn't help but say secretly. A pair of eyes couldn't help but look hard at the blade of this black broadsword!

Qin Duan is also a person who has seen a lot of artifacts, but the feeling that this black big sword gives Qin Duan is very different from those artifacts! This black big sword, the momentum it contains, I don't know how many times more powerful than those artifacts, the Dragon Slaying Sword, and the Dragon God Whip!

As soon as Qin Dui's divine sense explored this black big sword, he felt that this black big sword was like a vast sea, majestic and domineering, and there was no end in sight!
