The principal laughed twice, winked at Lin Xiao with a treacherous expression, and his tone and demeanor looked extremely relaxed, "What about the kid, do you want to bet with me." ”

"Damn!" Lin Xiao didn't have the heart to bet with him. The vampire doctor had already attacked him twice. Lin Xiao himself knew very well that it must be the school staff in the school who were secretly protecting him. Otherwise, the third, fourth, and fifth attacks would have already come.

Now, only the Darkstar disguised as the Headmaster knew he was here. Needless to say, the vampire doctor will soon find out as well. With such a good opportunity, he has now become a turtle in an urn, and it is absolutely impossible for a vampire doctor to give up such a good opportunity, no matter how stupid he is.

With a heavy snort, Lin Xiao looked at the principal and asked decisively, "How can I save you?" ”

The headmaster stood up with a smile, pointing unhurriedly at the bone that had pierced his chest. Lin Xiao actually saw clearly at this time that it was the tail of this bone dragon that penetrated the principal.

"Spill your blood here, as soon as the dragon's tail is broken, I should be free!" Hanging his head slightly, there was no longer any joke on the principal's face at this moment.

Lin Xiao didn't waste any more time and walked towards him quickly.

Anyway, the secrets of his genes have all been exposed, and Lin Xiao doesn't bother to hide anything. Raise your fingers, and the nails grow more than an inch long at a breakneck rate. Immediately, use your fingernail to cut the wrist of your other hand.

Suddenly, blood quickly emerged from Lin Xiao's wrist. Immediately, Lin Xiao shook his hand and threw the blood to the dragon's tail.

Lin Xiao's genes are different from ordinary people, and his blood is of course different from ordinary people. But neither in the outside nor on the inside, in fact, it is not expressed.

Until this time.

The blood had just touched the dragon's tail bones, and the sound of 'zila' came out immediately. It was like pouring a bottle of aqua regia, and white smoke immediately rose from the keel, and the white bubbles kept tumbling out. The keel that looked extremely hard was quickly corroded by Lin Xiao's blood.

"Roar!" Before he could breathe a sigh of relief, an earth-shattering roar came from above Lin Xiao's head.

The keel that filled the room shook violently like never before. The huge keel slammed into Qiang, and there was a terrible 'bang bang' sound.

On the keel, the strange 'dead air' that Lin Xiao had felt before also skyrocketed at this moment, and the temperature of the entire room dropped by more than ten degrees abruptly, and even a layer of frost appeared on the arm of the wall that was hit by the keel.

Needless to say, this bone dragon went berserk.

Before I could react, I heard a loud noise. The bone dragon pierced through the headmaster's tail and flicked violently, flicking the headmaster towards the wall.

The material of this building is very hard, and it only rattles under the impact of the bone dragon, and not even a trace of dust has fallen. If this really threw the principal against the wall, the consequences were unimaginable.

"Damn, I still have to shoot!" scolded again, how could Lin Xiao dare to let this bone dragon continue to flick its tail? With a fierce leap, he quickly jumped towards the dragon's tail.

Fortunately, the speed of the dragon's tail was not very fast, and Lin Xiao came first, but he caught up. It's just that he just touched the keel, and a violent sound came out again. Although the dragon's tail is not fast, the strength contained in it is amazing. As soon as he came into contact with the dragon tail, Lin Xiao felt that the bones in his body were about to be knocked apart.

Knowing that it was impossible to block this tail, Lin Xiao bit the tip of his tongue without saying a word, and spit out another mouthful of blood, which happened to be spit on the bones that were rapidly corroded by his blood.

The smoke accelerated, and the speed at which the blood corroded the keel suddenly increased.

It's just that in the end, I only heard a loud 'bang', and Lin Xiao, who was holding the dragon's tail, was thrown against the wall by the dragon's tail. However, before hitting the wall, Lin Xiao raised his palm and hit the dragon's tail that was corrupted by blood.

I have to say that I was lucky, the dragon's tail was about to break. Lin Xiao directly interrupted it with a palm, and finally saved the principal from this impact.

Naturally, the original point of impact was at the position where the principal was, although Lin Xiao still hit the wall, he was not too seriously injured.

Almost fell to the ground with the headmaster. After getting up from the ground, Lin Xiao immediately looked up at the bone dragon.

Sure enough, just as he thought, the bone dragon immediately raised its head and roared, and then bit the headmaster with its bloody mouth open.

As for the headmaster, when he got up from the ground, he gritted his teeth and stretched out his hands to pull out the bone that had pierced his body. Although the tail has been broken, the dragon tail bones still imprison his power.

Obviously, today's headmaster still doesn't have the strength to fight back.

Gritting his teeth, Lin Xiao lowered his head and leaned over towards the principal. Having already taken the first step, he naturally won't stop halfway.

Similarly, the speed of this bone dragon was not fast, although Lin Xiao moved backwards, he still grabbed ahead of it, and rushed out with the principal in his arms.

It's just that before he ran out of the dragon kiss attack range of this bone dragon, Lin Xiao's back was cold, and all the hairs on his back stood up.

The crisis is coming, and I already know that there is no escape. Lin Xiao hurriedly threw the principal in his hand hard, then quickly turned around and summoned all the scales on his body. He also took out a small piece of iron in his hand and lifted it up.

"Buzz!" With a bang, a layer of AT force field composed of regular pentagons emerged from the iron sheet in Lin Xiao's hand, and firmly covered Lin Xiao.

That is, the moment the AT force field just appeared, a black, but like a flame of dancing dense fog covered Lin Xiao's body.

"Bang!" This pitch-black flame had just sprayed onto the AT force field that was protecting Lin Xiao. With a soft sound, the AT force field shattered instantly. Immediately after, the black flames enveloped Lin Xiao again.

There is no terrible burning pain, there is a chill that penetrates the bone marrow. At the same time, I saw that the black scales on his body seemed to be alive, but they were withering rapidly. And in a very short period of time, the scales that seemed to have been eaten by the years fell down one after another.

What's even more peculiar is that Lin Xiao has already begun to try to absorb this black flame. But unlike usual, he couldn't absorb any energy from this black flame.

This black flame is not Yuan Force, nor is it Life Force. There was a breath of death.

But in the blink of an eye, all the scales on Lin Xiao's body had already fallen off. A terrifying chill pierced into Lin Xiao's bones. It was just at that moment that Lin Xiao felt completely unconscious, and only felt as if he had become a popsicle.

Fortunately, when Lin Xiao felt completely unbearable, the black flame disappeared.

But he didn't have time to rejoice, because although the black flame disappeared, a huge shadow hung over his head.

When I looked up, it was a bone dragon.

This guy still has a brain, and he knows that it should be Lin Xiao who should be dealt with now, so he began to decisively target Lin Xiao after a while. This huge shadow was precisely the one that lifted up and stepped on Lin Xiao's huge palm and foot accurately.

He cursed again.

And at this moment, the bone dragon raised its foot and stepped heavily towards Lin Xiao.

Although the black flame has disappeared, the effect of the black flame has not disappeared. At this moment, Lin Xiao only felt that all the bones in his body had turned into popsicles, and it was no longer possible to jump away.

There was no way, Lin Xiao could only grit his teeth, raised his hand to cut a hole in the forearm of his left arm, and at the same time as the blood gushed out, he raised his hand and threw it towards the huge soles of the bone dragon stepping down.

The sound of Zila was heard immediately, and the blood was the first to be thrown onto the soles of the bone dragon's feet, and quickly corroded the keel.

"Boom!" With a thud, the soles of the bone dragon's feet stomped heavily on the ground. It's just that when the violent sound came out, the huge bone dragon trembled wildly and began to sway from side to side, with a tendency to fall.

In the end, Lin Xiao's blood was superior, and when the bone dragon's foot stepped on him, the bone dragon's foot was corroded into a big pit.

The bone dragon's huge feet stepped on the ground, allowing Lin Xiao to escape. He quickly got up from the ground. Looking at the headmaster, he was still pulling out the broken bone in his chest. It's just that I can't see the slightest loose image, and I don't know if he can pull it out.

Now that it was difficult to ride a tiger, Lin Xiao could only snort, then turned in a direction and began to run again.

At this moment, the bone dragon had stabilized its body. There was another roar, swinging the broken tail and approaching Lin Xiao.

From beginning to end, the bone dragon did not do its best. It's not that it has the intention to play tricks on Lin Xiao and the principal. But in its eyes, a person like an ant, a half-crippled person, can't use it for all its strength.

But now it's different, three times and two times have suffered losses, which has completely aroused the ferocity of this bone dragon. He threw his head back and roared wildly, this time flicking his tail faster than he had at the beginning.

Not to mention escaping, Lin Xiao couldn't even see the movements of the bone dragon clearly, and the tail of the bone dragon slammed into Lin Xiao's body.

The huge force suddenly passed to Lin Xiao, and he felt that he was almost broken apart by this tail. His eyes bulged, and he spat out a mouthful of blood. Immediately, there was a loud bang, and Lin Xiao was thrown against the wall. Finally, even the incomparably hard walls could not withstand it. A crack like a spider's web instantly radiated out from the place where Lin Xiao hit.

Falling to the ground weakly, Lin Xiao instinctively wanted to get up. But when he propped his hands on the ground, an indescribable pain came out from between his arms and quickly spread to Lin Xiao's whole body. The soft click sound was like popping beans, constantly and quickly coming out of Lin Xiao's body.

It's the sound of bones breaking. That's right, just that tail, all the bones in Lin Xiao's body were already broken. Now, even if he gritted his teeth, there was no way to get up from the ground and move a step.
