"Woo woo!" The cave was pitch black, and a cold wind blew through the cave, and there was a whistling sound.

Ye Bufan was excited, and used the Nian Ghost Sword as a shovel, wanting to dig out the obsidian from the stone wall, but it was too hard, and he didn't expect the obsidian here to be so hard.

After a long day's effort, Ye Bufan finally dug out a piece of obsidian from above, thinking that he would dig it tomorrow, and it would not be too early.

After putting the obsidian into the bag, he came to this lord-level female earth bat to perform the blood refining technique, turning it into a blood crystal and two "blood-devouring" fangs.

This blood crystal is obviously very different from the blood crystal obtained before, it has been red to the point of blackening, and the energy contained in it is qualitatively different, Ye Bufan called it a second-grade blood crystal.

And those two fangs with the "blood devouring" rune were obviously higher in texture and sharpness than his own Nian Ghost Sword, no wonder he couldn't cut it by himself, and he could feel that the rune prohibition in it was clearer.

Ye Bufan put away these two things, walked in front of dozens of ordinary female earth bat corpses and concocted them in the same way, and obtained ten first-grade blood crystals full of energy, and dozens of ordinary fangs.

I took advantage of the night to leave here and go back to my "home", especially the guys who like night sky sneak attacks in the neighborhood, who were taken by themselves, and basically didn't need to worry about attacks from the air.

The wind along the way is getting colder and colder, even if it is Ye Bufan's strong physical fitness, he can't help but feel a little cold and biting, it seems that it is about to enter winter, and he seems to be ready for winter.

Ye Bufan was safe and sound along the way, did not encounter a powerful demon beast, returned to the "home", sorted out today's trophies and put them away, then took out a snake egg from the side and knocked it open, and drank this clear stream of egg liquid for today's dinner.

Originally, I usually planned to prepare for cultivation, but I was too tired today, so I just took a day off today, recovered my state, and went to dig obsidian tomorrow.

Nothing to say...

Early the next morning, he carried the sack on his back, went out, and set off to the bat cave where the obsidian was found yesterday.

However, they were running too fast in the trees, and they couldn't catch up with them in the trees at all, so they had to accept them when they saw that they were good, and refined the blood of these mouthed fire monkeys into crystals according to the custom, and obtained two first-grade blood crystals and four "Inflammation-eating" rune bones.

After Ye Bufan put away his things, he continued to hurry, and after a while, he came to the Bat Cave.

This place is too exposed, although it is much wider than his existing home, but Ye Bufan has no plans to move here, although the temple is small, it is safe.

The smell of the female earth bat here has not yet dissipated, and there will be no demon beasts to disturb him for the time being, so he started to dig obsidian, so Ye Bufan ran back and forth three times and finally dug back the remaining nine obsidian in this cave.

In the past three days, he has met some little demon beasts intermittently, and got five first-grade blood crystals, among which he also met a few Anri chickens, and made a real meal called flower chicken to taste, which made Ye Bufan have endless aftertaste!

And he also got the "Breaking Hua" rune of Ang Riji, which is a special ability that can interrupt the demon beast to temporarily strengthen itself with the help of the sun, moon and stars, but it is useless on the ethereal island.

That night, Ye Bufan was satisfied with admiring his trophies, there were eighteen first-grade blood crystals, one second-grade blood crystal, and eight of them were first-grade blood crystals of the upper quality, but they could not be compared with the second-grade blood crystals, Ye Bufan called them high-quality blood crystals.

Runic animal bones have "sharp" runes, "strength" runes, "hard" runes, "wood spirit" runes, "blood-devouring" runes, "inflammation" runes, and "breaking" runes.

He was going to refine the Nian Ghost Sword again tonight, last time due to the lack of blood crystal energy and various conditions, the refining was very rough, if it wasn't refined by a high-quality metal like Gengjin, it would be as good as his own claws.

In short, everything is ready this time, Ye Bufan is ready to refine the Nian Ghost Sword.

He rested for a while, adjusted his state, and then started the first step, drawing a blood refining array with blood, and then placing five blood crystals in the five elements in the array, forming a five elements blood refining array.

Then the second step was to stimulate the blood flame and separate the horns from the Nian Ghost Sword, which couldn't help but remind him that when he was refining the magic weapon gold bead in the bamboo forest, that kind of refining method was also the "Blood Flame Refining Method" that he had improved by his other self at the beginning, but he was fused with him, regardless of each other.

Ye Bufan placed the Nian Ghost Sword in the blood flame, sitting cross-legged as before, his face expressionless, and the brilliance revealed by those eyes could make people feel his full attention and seriousness.

The hands on his chest suddenly moved continuously, bringing up a series of phantoms.

The floating blood flame turned into an extremely thin white line of fire, like a tiny fire snake swimming around the Nian Ghost Sword.

Suddenly, the speed of the wandering line of fire increased sharply, only to feel that the red light in front of him was like electricity, turning and turning, end to end, and the Five Elements Blood Refining Flame Array was impressively formed!

The Five Elements Blood Refining Flame Array was formed, and the temperature in the cave suddenly became gloomy and cold. Even Ye Bufan couldn't help but shrink his neck, and the endless flow of flames made the cold meaning exuded even more stinging.

The Five Elements Flame Array is not too complicated to form a rune array, it can increase the power of the fire, whether it is yin fire or yang fire.

Every time the five elements are cycled, the power is doubled, and Ye Bufan can now complete up to two turns, and three times the power is completely enough for him at present.

With his eyes focused, all of Ye Bufan's thoughts were mobilized. Even if he is now a half-demon and his mind control has increased greatly, the second turn and five elements flame array is still extremely difficult for him.

Carefully control the blood flame with your mind, feel the energy within the blood crystal, and consume it at an astonishing rate, and the weariness of the mind that comes with it.

Ye Bufan held back, carefully controlling his thoughts, after all, it was the thing he relied on to survive the blood refining, and with a soft sound, the hilt on the Nian Ghost Sword turned into a bone bead in response.

Although Ye Bufan felt strange, he didn't have time to pay attention to this bone bead, and continued to control the blood flame, after the Gengjin sword body turned into three golden beads.

Ye Bufan finally breathed a sigh of relief, picked up the bone bead that had been mutated from the hilt of the sword on the ground, and saw that it was only the size of a fingertip, with a faint blood-colored texture on it, could it be that he had refined the purest "power" rune separately.

In order to prove his conjecture, Ye Bufan took out dozens of "blood-devouring" fangs and lord-level fangs from the side, and threw them into the blood flame, the blood flame turned into a fire snake again, wrapped around dozens of fangs, and controlled them with his mind, with a soft sound, dozens of fangs fused together and turned into a bone bead and fell to the ground.

Ye Bufan took it into the palm of his hand and looked at it, this bone bead had a clear texture, it had been red to black, and it had a dark red texture, which was obviously more powerful than the previous rune power.

It seems that it is possible to fuse the runes of the same kind together to become more powerful.

Then Ye Bufan made a conjecture again, took out the pair of golden horns and the power bone beads and threw them into the blood flame together, and after a while, the pair of horns merged into the power bone beads, and I saw that the blood texture on the bone beads became darker.

It seems that all this is the same as he thinks, I don't know if the different rune bones can be fused together, for the sake of insurance, Ye Bufan threw three kinds of rune bones that were not of much use into the blood flame, which were the three types of wood spirit, breaking Hua, and eating flame.

The blood flame turned into a fire snake again, burning violently at these three rune bones, and after a while, I saw that it turned into three bone beads and fell to the ground, it seemed that his conjecture had failed, and the five blood crystals finally turned into dust at this time, and the energy was consumed.

Ye Bufan also felt very tired at this time, and after resting for about an hour, he recovered his spirits and was ready to continue, took out five blood crystals and placed them in the array, rekindled the blood flames, and after getting the "Sharp Bone Beads" and "Hard Bone Beads" one after another, he stopped to rest again and adjusted his mental state to the best.

began to process and refine the obsidian, and was successively refined into ten black beads by him with blood flames, and in the void in front of him, the sky was empty.

On the surface of the black bead ground, there was a blood-colored flame burning, the temperature of the flame ground was obviously very high, but there was a cold meaning around it, and the black beads that were refined became even harder.

However, it is still gradually softening and becoming transparent under the refining of the flames, turning into a strange semi-fluid state.

I saw that Ye Bufan pinched the magic trick in his hand, and several small clusters of golden droplets were manipulated, and with a sword finger, these droplets instantly fused with the black liquid.

The metal liquid began to slowly elongate and flatten in the air, taking on the shape of a long sword, the obsidian liquid turned into the hilt of the sword, the heptogen liquid turned into the tip of the sword, and the sword body gave birth to several holes under the control of his mind.

Ye Bufan raised his hand and inlaid the "Strength Bone Bead" on the top of the hilt, and inlaid the "Wood Spirit Bone Bead", "Broken Hua Bone Bead" and "Inflammation Bone Bead" in the center of the sword hilt gauntlet, while the "Sharp Bone Bead", "Hard Bone Bead" and "Blood Devouring Bone Bead" were inlaid on the sword body by him.

With Ye Bufan inlaying the bone beads into the sword, a generation of magic swords "Nian Ghost" was finally born.

I saw a dark and dull, dark golden sword blade, inlaid with seven bone beads, with a dark red vein, like the blood meridians of living creatures, inserted into the ground.
