"Oh, is it?" Listening to the voice coming from the cliff, the originally complacent armor-piercing dragon suddenly became serious.

Its pair of vertical pupils stared at the cliff that Yun Fei had fallen into, and did not move away for a long time.

"Boom...... Several stones rolled down from the cliff, and a familiar figure flew out of the humanoid hole.

"This ...... How is that possible!" The spiny-backed armor-piercing dragon's pupils dilated several times, and it looked at Yun Fei in shock, unharmed, and was speechless for a while.

Yun Fei patted his arms lightly, and the pale yellow horizontal stripes on them quietly disappeared.

Yun Fei muttered to himself, "This big guy's dragon tail really wasn't blown out. If it weren't for the automatic appearance of the immortal horizontal stripes, maybe it would really be torn out of the skin. But...... It's just a broken skin. ”

Yun Fei silently suppressed the overflowing physical power in his body and replaced it with the Xuan Qi flowing in the meridians.

Yun Fei pulled out the black stick from his back, danced it slightly, and then rushed towards the thorn-backed armor-piercing dragon.

"Stupid big guy, dare you fight me!" Yun Feistick pointed ahead, his eyes wide.

"Hmph!" The spiny-backed armor-piercing dragon was provoked, and suddenly snorted coldly, it put away its surprise, and sneered: "Damn human, I want to see how many pounds and taels you have!"

"Bang!" The black sticks, one large and one small, completely disproportionate collided with the armor-piercing dragon, and suddenly there was an amazing collision sound.

The black stick in Yun Fei's hand changed direction, and the purpose was extremely clear towards the key points on the armor-piercing dragon's body, and the huge body of the armor-piercing dragon swayed from side to side, with the flexible and powerful dragon tail, taking Yun Fei's attacks one by one.

The battlefield of one man and one beast continued to spread, and inadvertently turned fifty or sixty miles!

Everywhere along the way, there was no grass, no chickens and dogs, and not a single living creature was left!

The sprawling body of the spiny-backed armor-piercing dragon fell to the ground, smashing a hole in the ground that was six feet deep. It was bleeding from the outside of its body, its expression was slightly tired, and the wound on its huge head felt stinging from time to time, but it didn't dare to stop at all, and quickly turned over and got up again.

After nearly two hours of fighting, the thorny-backed armor-piercing dragon had already understood the power of this human being, this body that was more than a hundred times smaller than it contained extremely huge energy, and his defense was even more terrifying, and he could only leave a shallow white mark on his body with all his strength, and he could not cause any substantial damage.

It tried to use its own occult skills several times to fight it out, but this human was like an annoying kraft candy, and it couldn't shake it off no matter what.

Yun Fei's side is getting braver and braver, the speed of the black stick in his hand is getting faster and faster, the Xuan Qi in his body is surging, and the feeling of being about to break through is getting stronger and stronger.

Finally......

Yun Fei let out a long breath, he took the initiative to widen the distance between him and the armor-piercing dragon, and streams of transparent Xuan Qi poured into the long stick, rendering it as black as ink.

"Look how to catch my trick!" Realizing that he could use his mystical technique, the thorn-backed armor-piercing dragon was stunned for a moment, and then couldn't help but feel a burst of ecstasy, and the mysterious qi in its body gushed out like a fate, and in the blink of an eye, an incomparably dark energy storm was condensed in front of him.

Looking at that energy storm, Yun Fei was not surprised, "Haha...... In that case, I can't hide it. ”

With that, the Xuan Qi in Yun Fei's body surged more and more, and the color on the long stick quickly changed three times.

"Three sticks in one!" A brilliantly colored stick flew out and met the energy storm on the opposite side.

"Boom Rumbling ......" The two intersected, and an indescribable storm of Xuan Qi suddenly appeared, quickly spreading out in all directions.

"Huh?" The four people, who were more than a hundred miles away, turned their heads sharply and looked behind them in disbelief, speechless for a long time.

"Could it be that besides us, there are other strong people who can't fight with that thorn-backed armor-piercing dragon?" The four of them were speechless and silent for a long time before slowly leaving.

"Let's not get involved in the fight between the strong. ”

In the battle circle, Yun Fei's head was slightly chin and his eyes were closed, as if he had some understanding.

The spiny-backed armor-piercing dragon on the opposite side was lying on the ground weakly, looking like it was being slaughtered, where was there still a little bit of majesty before.

Speaking of which, Yun Fei is indeed a bit invincible, although the dozen or so guys in front of him did not cause fatal damage to the armor-piercing dragon, they consumed a lot of its strength, and at this moment, fighting with Yun Fei, it naturally suffered a lot.

But then again, even if there were no dozen or so people in front of him, the full state of the armor-piercing dragon would only have a dead end for Shangyun Fei.

At this moment, Yun Fei, as the victor, did not speak, and the thorn-backed armor-piercing dragon of the defeated side could only lie on the ground obediently, not daring to do anything excessive.

It took a full hour for the Xuan Qi operating in Yun Fei's body to completely regain its tranquility, and he only then opened his eyes and looked at the thorn-backed armor-piercing dragon on the ground.

"......" Before Yun Fei could speak, a sound of breaking wind sounded, and the person who came was naturally Xiao Zi who was squatting on the side.

"Congratulations to the master for a successful breakthrough!, what should I do with this big guy?" Xiao Zi's eyes looked at the thorn-backed armor-piercing dragon unscrupulously, and there was not the slightest respect for this demon beast king in his eyes.

Listening to Xiao Zi's words, the body of the armor-piercing dragon couldn't help but be a few points lower, it turned out that this human had broken through again.

It had already been defeated by Yun Fei before, and now, it was even less of an opponent. And this woman who suddenly flew over was not an ordinary person, and her speed made the armor-piercing dragon dumbfounded.

The armor-piercing dragon also wondered, why had he never heard of it before, the strength of this master and servant was so strong?

Listening to Xiao Zi's question, Yun Fei couldn't help but smile, he had no grievances with this thorn-backed armor-piercing dragon, and he had just broken through with its power, speaking of which, he had to thank it, how could he deal with it.

Yun Fei didn't know that his smile fell in the eyes of the armor-piercing dragon, it was the devil's smile, terrifying.

Before Yun Fei could speak, the thorn-backed armor-piercing dragon took the lead in speaking: "I beg the two adults to forgive the younger one, and the younger one is willing to give away all the scale armor on the dragon's tail." ”

"Huh?" Listening to the words of the thorn-backed armor-piercing dragon, Yun Fei's eyes suddenly lit up, the hardness of this big guy's dragon tail scales is clear to himself, and he can fight directly with his own Qi He Tianyuan Stick, and the quality is naturally guaranteed.

Although Yun Fei's own defense is amazing, Xiao Zi is not very good at this, if he can use its tail scales to make a set of armor for Xiao Zi, it will be very good. And listening to the meaning of the thorn-backed armor-piercing dragon, removing its tail scales will not cause any fatal damage to it.
