Demon cultivators, enter the realm very quickly, but the shortcomings are also obvious, their foundation is not stable, and the true yuan in their bodies is not condensed enough, they can win with the domineering of demonic qi in a short battle, but if it is a protracted battle, it will be very disadvantageous to them.

Although Xu Qing was able to fight with the man in black without distinguishing between victory and defeat, in the final analysis, it was because his mana was more condensed, but if it was really about the depth of his mana, Xu Qing was still weaker than the man in black, and when fighting with the man in black, he mostly relied on the way of fighting, but after all, he had just reached the middle stage of foundation building, which was already very good.

Therefore, after an hour of fighting, Xu Qing had no more true yuan left in his body than the man in black, but his foundation was solid, and his recovery ability was much stronger than that of the man in black.

Xu Qing quietly took out a high-grade spar and held it in his hand to recover the consumed mana. The higher the grade of the spar, the faster the recovery of mana, the upper grade spirit stone is almost only the circulation between the high level of the Yuan Infant, a high-grade spirit stone is equivalent to 10,000 low-grade spirit stones, the aura contained in it can be imagined, it is really good to use it to restore mana.

"If you are willing to suppress the cultivation in the middle stage of foundation building, I will confront you head-on, and never run away again, what do you think of this?" Xu Qing pouted and said, what he needed to do now was to delay time, and the longer the time, the better it would be for him.

"If you give me Shui Linglong, I will turn around and leave now, and I will never embarrass you, what do you think?" the man in black made this request again.

"Okay, as long as you give me 10,000 spirit stones, I will give you the water exquisite. Xu Qing said with a smile.

"Damn, if I don't kill you today, it will be hard to eliminate the hatred in my heart. Now, even if you hand over Shui Linglong to me, don't think that I will take your life. The man in black said hatefully.

"If you have that ability, come and take my life. Xu Qing pouted and said.

The man in black closed his hand tightly and stretched out the spear in his hand, pointing directly at Xu Qing. The next moment, the man in black was surrounded by demonic energy, and his aura fluctuated, like a heartbeat, as if a forbidden force had awakened in his body.

The original cyan spear body was also the same as the silver spearhead, all of which became pitch black, and the spear was even more demonic. At this time, the spear seemed to be completely connected with the man in black, and the domineering aura that the spear originally emitted was gradually weakening, and a yin and strange aura was gradually growing, and finally it could change the color of heaven and earth.

At this time, how could Xu Qing not know that the other party was using a powerful secret technique, he cautiously retreated a few feet away, if the situation was slightly wrong, he could also escape as soon as possible.

The man in black suddenly opened his eyes, and a supreme aura burst out from the spear, and the demonic qi surged, just like the birth of the Demon Lord of the World, and the heavens and the earth were about to change color.

Under Xu Qing's gaze, the pitch-black spear suddenly floated out a cloud of demonic energy. The demonic qi is uncertain, at the beginning it is only the size of a fist, and the breath is not strong, but in the next moment, all the demonic qi is quickly inhaled into the demonic qi like a long whale absorbing water, and the demonic qi is also constantly growing, and the breath is getting worse and worse.

The man in black's face instantly turned pale, and his spirit became very sluggish, and he would generally have to pay a great price to perform a powerful attack secret technique, obviously the man in black was in an extremely bad state at the moment, if he couldn't win with one blow, he would have to worry about his life.

The demonic energy was surging, and finally turned into the image of a demon lord, with three heads and six arms, two wings on his back, and two horns on his head, which looked extremely hideous and terrifying.

This secret technique is very powerful, but the cultivation of the man in black is too weak, far from being able to exert the true power of the secret technique, Xu Qing has no doubt that if this secret technique exerts its true power, it can destroy the heavens and the earth and slaughter the ten directions.

A white silk scarf hovered in front of Xu Qing's body, and layers of thick light curtains spread out from the silk scarf, like a vast ocean, sealing Xu Qing's front to death.

The man in black sneered and shouted softly: The Demon Lord has destroyed the world, this light drink seems to have exhausted all his strength, his face is becoming more and more pale, and the control of the flying sword is already extremely unstable, he does not dare to delay, and hurriedly falls down.

The demon lord formed by the demonic qi, his eyes showed a monstrous fierce light, and the breath of killing was growing wildly, and then he swept directly towards Xu Qing, at this moment in his eyes there was only Xu Qing, and there was nothing else, he had only one thought, there was to kill Xu Qing, although it was in the air, he was walking on the ground, and there was no trace between his actions.

Xu Qing took out a large handful of spirit runes from the storage bag, both low-level and high-level, and there was even a Xuan-level spirit rune in it, but without exception, these spirit runes were all fire-type spirit runes.

The Demon Lord had not yet approached, but it had already grown its mouth, as if it was about to swallow Xu Qing into its belly, and the long sharp fangs in its mouth were clearly visible.

"Roar!"

The Demon Lord roared angrily, and the heavens and the earth changed.

When Xu Qing roared in the Demon Lord, his mind suddenly fell into chaos, as if he had forgotten everything, he hovered in the air in a daze, and the spirit rune was firmly held in his hand, forgetting to activate it.

By the time Xu Qing recovered from the chaotic state, the Demon Lord's six arms had already plunged into the sea of light curtains formed by the square silk scarf. The sea of light curtains, which were extremely powerful in defense, dispersed almost instantly, and the ?? The light also dimmed, and slowly fell.

Xu Qing quickly retreated, and quickly propped up the body protection aura, at this time, it was too close to the Demon Lord, and it was no longer effective to activate the spirit rune.

Xu Qing hurriedly recited the mantra silently, and a jade pagoda slowly appeared in the palm of his hand, and at this time, the demon lord's pitch-black arm had already slapped fiercely on Xu Qing's body protection aura, and the body protection aura light flashed rapidly a few times, and then shattered.

With the help of this powerful impact, Xu Qing retreated even faster, although the corners of his mouth were gushing blood, he didn't care, and still concentrated on reciting the mantra. Xu Qing's speed was fast, but the speed of the Demon Lord was even faster, and in just one breath, it caught up with Xu Qing again, and then several pitch-black demon arms slapped at Xu Qing fiercely at the same time.

Although after two blocks, the demonic qi dissipated a lot, and the figure of the demon lord was blurred a lot, but it was definitely not something that Xu Qingfan's fetus could resist. The Demon Lord's face was hideous, as if he was complacent about the imminent killing of Xu Qing.

Xu Qing quickly pinched a seal and printed it on the golden belt around his waist, and a burst of golden light suddenly appeared between Xu Qing and the Demon Lord. The Demon Lord once again reached out of his pitch-black arm, and the golden light curtain was instantly torn to pieces.

The man in black had been paying attention to the situation in the air below, and at this time, he saw that the last barrier between Xu Qing and the Demon Lord had also dissipated, his face was full of excitement, a trace of ruthlessness flashed in his eyes, and then he shouted softly: "Explosion!"

The figure of the Demon Lord began to expand dramatically, becoming more and more huge, and finally exploded into pieces with a "bang", and the demonic qi raged in all directions, a layer of clearly visible ripples spread in the air, and the destructive aura was stirring.

"Haha, it's not in vain that I spent ten years of life to use the Demon Lord to destroy the world, hehe, boy, aren't you very good at escaping? The man in black stared at the air tightly, and only laughed after making sure that Xu Qing had completely disappeared, but he didn't notice that a small turquoise tower was shooting away into the distance under the impact of demonic energy.

"I didn't see anything fall just now, it seems that the storage bag is not broken, fortunately it is not broken, otherwise Shui Linglong may not be able to keep it. If the storage bag is destroyed, then the items inside will be scattered, and the man in black breathed a sigh of relief when he saw that there were no items scattered, after all, if Shui Linglong was scattered, it would definitely be destroyed by the monstrous demonic turmoil.

The man in black was not in a hurry, he sat cross-legged and began to breathe, just now he used the Demon Lord to destroy the world, not only did he consume ten years of life, but the consumption of his true yuan was also extremely large, and at this moment, the mana in his body was almost completely exhausted.

At this time, a shocking flood in the distance quickly shot towards him, and before the shocking flood arrived, a brilliant sword qi had already slashed towards him. Although the man in black was pranayama, he was always cautious, and when the sword qi was slashed, the demonic qi on his body soared, and the aura of body protection was quickly opened.

"You didn't even die, how is this possible?" The man in black had already seen who the attacker was at this moment, and he looked at Xu Qing who shot from afar with a shocked expression.

After all, the man in black was almost exhausted, and the aura of the body protection was shattered in response, and the man in black took several steps back in a row to stabilize his figure. At this time, several sword qi shot out, and the man in black had a panicked face, and hurriedly flashed to the side, opening his mouth to say something, but Xu Qing didn't give him a chance to speak at all.

Xu Qing landed a few feet away from the man in black, and the spirit sword in his hand burst out with countless sword qi, and finally, the endless sword qi almost overwhelmed the man in black. The screams came, and the breath of the man in black quickly disappeared completely.

As soon as the man in black died, Xu Qing spurted out a mouthful of blood, his face became pale and abnormal, and his body was a little unstable, shaking slightly. Xu Qing didn't care about counting the spoils, and immediately sat down and began to breathe.

Just when the Demon Lord blew himself up, although Xu Qing hid in the Jade Pagoda in time, he was still a beat slower after all, and the rolling demonic qi hit his back at the last moment, and he was seriously injured as a result. He hid in the jade pagoda in time, so the impact of the demonic qi was only a small part, and it was not much of a threat to Xu Qing, but when the demonic qi hit his back, a wisp of demonic qi invaded his meridians.

Since ancient times, the good and the evil are not separated, and the true yuan in Xu Qing's body immediately had a violent conflict with the demonic qi. But in order to miss the opportunity to kill the man in black, Xu Qing just mobilized Zhenyuan to temporarily suppress the demonic energy, and then went to kill the man in black.

Although he successfully killed the man in black, the demonic energy also backlashed at this time.

An hour later, Xu Qing was still pranayama with his eyes closed, his breath stabilized a lot, and his face returned a little ruddy. After another half an hour, his forehead suddenly became drenched with sweat, and his muscles were throbbing, as if he was in great pain. This situation did not last long, and the next moment, the pores on Xu Qing's body began to slowly escape a trace of demonic qi, and after a stick of incense, the demonic qi completely stopped escaping, and Xu Qing's face gradually returned to calm.

Two months later, Xu Qing finally rushed to the Longyan Mountain Range, and in order to avoid trouble, Xu Qing still disguised his strength as the Great Perfection of Qi Refining, and healed his injuries while hurrying.
