Xu Bing's body was floating in the pool of water at the moment, and after closing his eyes, he began to exhale, the pool water that was originally rich in aura, after he began to exhale, the aura in it quickly seeped into his flesh and blood and dantian along his mouth, nose and the skin on his body.

At noon, Xu Bing went out with Ma Yujian and fought with the pig demon, although the demon beast was not Xu Bing's opponent, Xu Bing was not injured at all.

But this kind of battle still has a certain consumption of the aura in his body, which is greater than carrying those stones in the morning.

At this moment, he was in the pool of water, feeling the cool feeling brought by the spiritual energy entering the body, which made the spiritual energy in his body recover rapidly, and even his cultivation was constantly improving.

Xu Bing could feel that although the pool dug by the master in this cave was not large, the aura in it was strong, and it seemed to be imprisoned by the master in a special way, so that the aura in it accumulated more and more, and it would not disperse along the surrounding soil and rocks.

Xu Bing practiced in this pool of water for a whole night, and it was not until the sun rose high the next day that he was shouted out of the cave by Ma Yujian.

After Xu Bing came out, he looked at Ma Yujian with some puzzlement and asked, "I don't know why the master called the apprentice out?"

Hearing Xu Bing's words, Ma Yujian rolled his eyes, blew his beard and said, "What's the matter, old man, I must have something important to do when I call you out."

As he spoke, he raised his right hand again, pointed to the west, and then said to Xu Bing, "Five miles to the west, there is a black-armored demon soldier haunting, old man, I ordered you to be the generalissimo of the demon eradication, and immediately go to destroy the black-armored demon army."

When Ma Yujian said this, his face was serious, which made Xu Bing, who was listening to him on the side, puzzled, but he still agreed to Ma Yujian, and flew away with a dagger in the direction that Ma Yujian pointed.

After Xu Bing left, Ma Yujian reached out and stroked his beard again, looked at Xu Bing's distant figure, and nodded with great satisfaction.

After Xu Bing left, there was still a trace of doubt in his heart, the black-armored demon army that Shizun said in his mouth, I don't know what it was, but it should also be some kind of demon beast in this mountain forest.

Xu Bing flew all the way forward, but he was cautiously observing his surroundings, always alert to possible dangers.

After flying like this for a while, Xu Bing's body finally stopped in one place.

At this moment, in front of him, more than ten zhang away, there was a large black light and shadow on the ground, but the strange thing was that this black light and shadow was constantly changing.

Xu Bing could feel that the sense of crisis coming from the black light and shadow far exceeded that of the wild boar-like demon beast before.

He hid his aura as much as possible, and slowly moved forward a few feet, only to see clearly that the black shadow was actually composed of countless black beetles.

The beetles were small, the largest being no bigger than the size of a thumb, and on the top of their heads, they had a long spike, and at the moment they were huddled together, piercing down with the spikes on the top of their heads.

Xu Bing found that there seemed to be a demon beast on the ground that had died not long ago, and it looked like a tiger, and he could feel that the cultivation of this tiger-shaped demon beast before its death was probably not lower than the seventh-fold mortal realm, it was a demon beast in the late stage of the first order.

And among the black beetles in front of him, the highest cultivation is only the mortal body realm threefold, and most of the rest are mortal body realm one, and there are less than a hundred.

However, when Xu Bing found the corpse of the tiger-shaped demon beast, he began to slowly retreat backwards. Because in front of him, the corpse of the tiger-shaped demon beast was densely packed with the black beetle demon beast, although the cultivation of such a demon beast was not high, but its number was too large, at a cursory glance, there were more than a thousand, so many black beetles, let alone Xu Bing, even if the tiger-shaped demon beast was alive, it was only left to be eaten alive.

Xu Bing had already tried his best to hide his aura when he approached, and he was not noticed by any black beetles when he observed, and he was also slowly retreating back at this moment.

Seeing that he was about to leave here, a voice suddenly came from behind him, causing nearly half of the black beetles that were originally eating seriously to turn their spikes in the direction where Xu Bing was.

This voice Xu Bing was familiar with, it was from his unreliable master, he only said, "Good boy, come for the teacher", and then there were no more words, Xu Bing turned around, and did not see his figure.

And at this moment, in the valley, Ma Yujian was lying on the grass, looking lazy, but just before a breath, his mouth opened and closed for a while, but it was extremely short, and he didn't seem to make a sound.

After Xu Bing heard Ma Yujian's voice, he secretly said something bad in his heart, and turned around to find that there was no figure of Ma Yujian, and at this time, dozens of those black beetles had already given up on the corpses of demon beasts on the ground, and flew towards where he was.

Seeing such a scene, even with Xu Bing's temperament, he couldn't help but burst into a foul mouth, but there were more black beetles behind him, so he didn't dare to attack, but used his speed to the extreme, and flew directly towards the place where the valley was.

During the flight, Xu Bing found that the number of black beetles chasing after him was increasing, and when he returned to the valley, there were nearly two hundred black beetles behind him.

Xu Bing glanced around, but did not see Ma Yujian's figure, and couldn't help muttering a few words in his heart, is Shizun letting himself practice, or is he going to directly ask for his own life, so many black beetles, how should he deal with it.

However, Xu Bing didn't have much time to think, and the moment he paused, nearly ten black beetles flew to his side.

These black beetles could smell the fluctuations in his cultivation, but they didn't seem to be afraid of it, like moths to a fire, they directly raised the spikes on their heads and stabbed at Xu Bing.

Although Xu Bing hadn't figured out how to deal with it yet, he wasn't panicked, and there were less than ten black beetles coming to his side at this moment, and he could completely deal with it with his cultivation.

I saw that he took back the dagger, blocked it directly in front of his chest, and at the moment when those black beetles came, he directly used the exorcism technique to slash those black beetles.

But these black beetles are smaller, and their speed is not weak, Xu Bing's slash actually killed only one black beetle, and the others did not touch it.

Moreover, after seeing their companions being killed, the remaining black beetles were also like crazy, and their wings flapped continuously making bursts of buzzing sounds, attacking Xu Bing again.

Behind them, there were more than a hundred remaining black beetles, which also rushed towards Xu Bing.

In the face of so many black beetles, Xu Bing didn't dare to resist at all, and directly retreated a distance of several zhang away, quickly casting a spell in his hand, and instantly condensed two thunder arrows with a length of three inches, and with a swing forward, it directly collided with the swarm of black beetles flying at great speed.

Hearing only two booms, a burst of explosive light exploded, and dozens of black beetles in the flight suddenly turned into fragments and fell in all directions, leaving about two-thirds, retreating a few feet, hovering in the air for a while, and then rushing towards Xu Bing again.

When Xu Bing saw this, his heart suddenly felt depressed, these black beetles seemed to be really not afraid of death, even if one attack killed so many of their companions, they still did not stop attacking, and they seemed to be more fierce than before.

Xu Bing was helpless, although the burden of the thunder archery technique was not too great for his current cultivation, with the aura reserves in his body, he could use the thunder archery technique up to five times, and after five times, the aura in his body would all be exhausted, if this was the case, then he would only have to wait for death.

However, Xu Bing is a killer after all, although he has not experienced such a scene before, but it is not the first time for him to face life and death.

At this time, he would try his best to suppress the timidity in his heart, so that it would be easier for him to calm down and think about how to solve the danger in front of him.
