The clouds were thick, the cold wind was gusting, the wind was getting cooler and cooler, and the dark cave was full of the breath of slaughter.

Ye Bufan looked at it a little nervously, the huge female earth bat in front of him was obviously not at the same level as those female earth bats inside and outside the cave.

It is very willing to be a lord-level existence in this cave, and at this time, it occupies a favorable position in this battle, which is not a good thing for itself.

From the moment it bit its own blade, the corners of its mouth were still fine, proving that it was hard, and it was not something that the current Nian Ghost Sword could break through.

And now escape will only become its meal, it seems that it can only be tried by beating the pheasant.

The two sides held each other like this for a while, looking at each other, and the female earth bat took the lead in launching an offensive with her strength.

I saw its woman-like face, opening its big mouth and letting out a burst of screams, which echoed everywhere in the cave wall, causing a lot of interference, especially for a hearing superman like Ye Bufan, which was the most deadly.

"Ahhh

Ye Bufan was pierced by this scream, his eardrums were in great pain, deafening, and even his consciousness was affected, he was a little dizzy, and hurriedly covered his ears with both hands, but this was like looking at Mei to quench his thirst, with little effect.

Seeing this, the female earth bat immediately seized the opportunity and launched a surprise attack, only to see it accelerate in the air, and there were two sharp hook claws on the bat's wings.

When he was close to Ye Bufan, he suddenly stretched straight in front of him, as fast as lightning, and stabbed towards Ye Bufan's chest.

And at this time, although the female earth bat stopped sounding, the echo in the cave was screaming, and it was still echoing.

"Roar!"

At this moment of crisis, Ye Bufan seemed to be stimulated by the power of the blood in his body, and instinctively roared out a burst of tiger roar and thunder to forcibly disperse the residual scream.

In the middle of the cave, the momentum of the female earth bat was also paused, but at this time, Ye Bufan's feet were electrified, with a burst of "Bilibili" electric light.

Like a light and shadow, it flashed in front of the female earth bat, and the powerful wind-breaking energy, the Nian Ghost Sword carried a thunderous sound under the blessing of the power rune, and smashed heavily on the top of its head.

"Bang!" The dull sound and the huge power on the Nian Ghost Sword suspended the female earth bat's body in mid-air and slammed it down to the ground.

As a lord-level demon beast, this female earth bat was obviously not so fragile, and it only fell to the ground for less than half a moment, and then kicked her feet and stood up like this.

The female earth bat looked at Ye Bufan with a cold light, as the overlord of this area, it suddenly felt unhappy, and was shocked by the sound of tiger roar and thunder just now.

It didn't know that the guy in front of it had suddenly become a lot of victims, but its intuition told it that this guy was not its opponent yet.

At that moment, the female earth bat screamed at Ye Bufan, and at the same time, the two bat wings were retracted, and the two hook claws hooked the ground, like a four-legged beast rushing.

The speed was extremely fast, not much slower than the speed at which it flew, and when it was approaching, it jumped up towards Ye Bufan, and shot out with four claws at the same time, directly taking Ye Bufan's face.

Ye Bufan's hearing was affected again, and he didn't have time to react to dodge, so he had to protect the Nian Ghost Sword in front of him in a hurry.

"Bang!"

Ye Bufan even carried a sword, and was repelled several meters by Shengsheng, and a bloody mark was scratched on his face.

The female earth bat is like a master with a sword, a blow is fruitless, and the hook claw does not stop, and it slashes out horizontally.

With a cold light on the tip of the claw, it swept past Ye Bufan, who was repulsed, and on his chest, a shallow blood mark was drawn again.

Then without waiting for Ye Bufan to react, a hook claw suddenly hit the sword body where Ye Bufan was about to take out the sword, shaking the Nian Ghost Sword away, and suddenly stretched out another hook claw and turned into a cold light, shooting towards Ye Bufan like lightning.

The speed of the claw light was extremely fast, even if Ye Bufan's reaction was not slow, he was still left with a bloody mark on his face by the female earth bat.

Ye Bufan took the opportunity to take a few steps back, widened the distance, licked the blood flowing from his face with his tongue, his eyes were filled with a strong killing intent, and he sneered: "Dead bat, you are dead, you forced me!"

As he spoke, Ye Bufan reached out and took out a piece of blood crystal, held it in his mouth, and on the surface of his body, a faint blood-colored aura began to loom, and he held the Nian Ghost Sword tightly in his hand.

The female earth bat looked at the degree of this guy's sensing and reacting to danger, far beyond her expectations, it was not bad, like an adult man.

The female earth bat noticed that his aura had become a little strange, but her own strength did not care about his changes.

When the soles of his feet slammed on the ground, like a giant demon beast, they rushed towards Ye Bufan in a rampage, and at the same time let out bursts of screams, disturbing his consciousness.

Looking coldly at the female earth bat that pounced with a screaming sound, Ye Bufan's Nian Ghost Sword in his hand slowly stretched out, and after an instant, he suddenly swung out a sword, and roared at the same time: "Roar...!"

As Ye Bufan's roar fell, the surrounding screams suddenly dissipated, and the fierce blood-colored sword qi suddenly erupted from the blade, hitting the body of the female earth bat that rushed violently.

"Bang!" There was a muffled sound, the bloodthirsty expression on the woman-like face of the female earth bat froze slightly, the hook claws on the bat's wings hurriedly crossed to protect the front of the body, and the forward body shot out suddenly, and the hook claws on the soles of the feet clung to the ground, until a deep ditch several meters away was brought out on the ground, and then it slowly stopped.

Ye Bufan saw that he repelled the female earth bat with a blow, and did not stop there, Feiyan stepped under the blessing of blood and qi, his body was as light as a swallow, as fast as lightning, and rushed to the front of the female earth bat in the blink of an eye, the blade was wrapped with blood-colored sword qi, and a sword burst out, flashing sword light, like a blood-colored pillar of light, passing through the bat's wings and inserting it into its body for three points, but Ye Bufan did not let go, the dantian spirit surged, and he clenched the hilt of the sword with both hands and continued to push hard, and the female earth bat resisted the blade of the sword to the death, and could not let it enter the slightest.

"Ahh

"Poof!"

After all, the female earth bat couldn't support it anymore, the sword blade passed through its body, and Ye Bufan then clenched the Nian Ghost Sword and stirred it in its body, scattering its only remaining breath in an instant, and the female earth bat of the lord of the hole died under the sword after all.

"Whew!"

Ye Bufan breathed a sigh of relief, let go of the Nian Ghost Sword, and sat on the ground with his buttocks, regardless of whether there was bat poop on the ground.

When he sat down, he found that the ground was very clean, and there was no poop, but at this time, he was seriously overdrawn and had no strength to stand up again, even if there was, what could he do?

In the battle just now, seeing that he was about to be defeated, and under the critical situation, he suddenly remembered that the power of blood crystals when refining the stomach and soil pheasant could obviously be used, an energy that was no less than spiritual power.

At that time, he couldn't allow himself to think too much, and he was forced to have no choice but to try whether the power of the blood crystal could be used as spiritual power to use sword qi, so that he would have a chance to break through its defense.

As a result, he successfully triggered a blood-colored sword qi, reversed the situation, and finally killed the female earth bat.

However, using this power is very taxing on the body, and it is as uncomfortable as being in a furnace.

Moreover, a piece of blood crystal refined by the three Kui wood wolves seems to be only enough for himself to produce two swords, and it seems that using the power of blood crystals to promote sword qi is not as consuming as his own strength.

And once the power of the blood crystal is exhausted, he will be powerless, and it seems that this combat method of using the blood crystal to promote sword qi can only be used as a pressure box to save his life.

Ye Bufan regained a little physical strength, and when he sat cross-legged and pinched the last blood crystal in his hand to cultivate, he used cultivation to recover the physical strength and exhaustion he had consumed.

After all, on the way back, there may be some dangers, so that the body can recover to the point where it can avoid danger in case of accidents.

After about an hour, several scars on his body have scabbed, and his strength has recovered a lot, and the rest can only be replenished by eating.

Ye Bufan stood up and looked around, and found that he had unconsciously entered the depths of the cave with the battle, it seemed that this was the place where the female earth bat slept, his eyes swept around, and he suddenly paused, and exclaimed with joy: "Obsidian!"

Obsidian is a special metal ore that is gold and non-gold, and is a special metal ore that is not stone, which has very good compatibility and is the best choice for refining magic weapons with monster materials.

Obsidian only occurs organically in dark and dark places, and it takes thousands of years to generate a piece, and it is highly recognizable because of its unique light-absorbing properties.

Due to the harsh generation conditions, it is not so easy to find, and it is a rare ore.

For these reasons, obsidian can be said to be a rare refining material, and it has been rated as one of the top ten rare ores.

At this time, Ye Bufan saw dozens of obsidian inlaid in the stone wall, the size of a fist.

This is simply the refining material that Ye Bufan dreamed of, there are so many at this moment, smashed in front of his eyes, happiness came so suddenly, he didn't know how to express his current mood for a while.
