Looking at the sudden shocking changes, everyone was a little confused, but it was precisely because of this unknown thing that it made people feel more uneasy and scared.

To everyone's surprise, an old man behind Wang Fei was very excited at the moment, his body couldn't help but tremble slightly, with a look of horror on his face, and after a while, he trembled and pointed at the black clouds in the sky and said: "This, this is the art of blood sacrifice, my God, this beast can actually use the art of blood sacrifice!"

When everyone heard this, they couldn't help but look back at the old man, with a puzzled face.

"This brother, when is the blood sacrifice technique?"

Leng An arched his hand at the other party and couldn't help but ask.

"I heard in an ancient book before that this kind of blood sacrifice technique is a forbidden art, through one's own essence and blood to sacrifice, once it is cast, something against the sky will happen!"

Under the gaze of everyone, the old man immediately arched his hand and explained to everyone.

"Something against the sky?"

Hearing this, everyone couldn't help but gasp, even Xu Xuan's expression became extremely dignified, although it was not clear, giving people a vague feeling, but the word against the sky made people feel extremely frightened.

Many people are even secretly thinking about whether to leave now, the word against the sky is really terrifying.

"What are you afraid of? We cultivators are acting against the sky, increasing longevity or something, isn't it against the sky?"

No one thought that at this time, Xu Xuan's voice was slowly spreading here, and then, he glanced at the black python in the middle: "What kind of anti-heaven method do I want it to be!"

Leng An and the others couldn't smile bitterly, this guy was really arrogant and ruthless, but Xu Xuan's words made many people who were a little shaken feel a lot more relieved, after all, they Xu Xuan could still stand here alive and talk to them after colliding with the black python, which was already an extremely ungodly thing.

In the center of the crowd, above the head of the black python, a huge black cloud slowly pressed down, making the sky here couldn't help but darken.

As soon as the essence blood of the black python entered the black cloud, the black cloud actually rotated slowly, and finally it stopped suddenly, and a black beam of light shot down from the black cloud.

This black beam of light was impartial, and it shot directly on the bloody wound on the abdomen of the black python's demon, and then something that made people feel against the sky really happened.

The blurred flesh and blood of the wound actually grew flesh and blood at a speed that could be seen by the naked eye, and in just a few breaths, the black python's injury was completely restored, and its momentum was also improved to the same appearance as at the beginning.

As the black python's injury healed, the black cloud immediately dissipated, and the sky returned to its previous appearance, as if nothing had happened, but when everyone looked at the intact black python's previous wound, everyone knew that this was a fact, a fact against the sky.

"Oh my God, it's recovered, how is this possible!"

Nangong Yu's face was shocked, everything that happened in front of him was really against the sky.

"What can we do? Shall we continue to fight?"

Someone couldn't help but start to say, with a depressed look on his face, he made such a big sacrifice, and everyone also spent a lot of mysteriousness, and now the black python actually has such a secret technique.

The old man before, after thinking about it, couldn't help but smile bitterly: "Such a secret technique against the sky can usually only be performed once, but under the situation of long-term and long-term, our chances of winning are a few points less." ”

When everyone heard this, they all nodded in agreement, some people here have already been injured, and there are many people who have less than half of the Xuan Qi left in their bodies, however, what they need to face is the black giant python that has been resurrected to its peak state with full blood, and its strength is comparable to that of the demons in the early stage of the Dan Xuan Realm.

Leng An, Wang Fei, and Du Yu and other masters also turned extremely difficult, and the only thing to be thankful for is that this anti-heaven secret technique can only be used by the other party once, otherwise, today will really be dead.

"What are you afraid of, everyone's senior brothers and brothers can't die in vain, at this time, wouldn't it be too worthless to quit, besides, do you think it will let us leave easily?"

Xu Xuan smiled coldly and said again, but there was a faint doubt in his heart, the Nine Swallowing Divine Jade could recover his injuries, and this secret technique could actually repair his injuries, but the time of one was very slow, and the time of the other was extremely fast, I don't know if there is any relationship between the two.

Of course, if you can't figure it out, Xu Xuan won't think about it too much, he was not seriously injured before, and he is almost recovered at the moment, he doesn't like to give up halfway, in order to give everyone some encouragement, he actually took the lead, and after finishing speaking, he rushed towards the black python in a flash.

"Good boy, I didn't expect you to be quite tenacious, it was really beyond my expectations. ”

The black python couldn't help but be a little surprised when it saw that Xu Xuan dared to take the initiative to rush towards it when he had recovered to his peak state.

"Hehe, there are many things that you didn't expect. Berserk!"

Xu Xuan said in a cold voice, after finishing speaking, he saw that his fingers in the air suddenly changed, and finally his body shook suddenly, and the surface of his skin was faintly glowing with a slight red, and then he felt that the power in his body increased by several points in an instant, as if it was full of infinite power.

"Whew, that's a really good feeling!"

Suddenly, his strength increased by nearly ten percent, Xu Xuan felt that his muscles were about to be exploded by the power, the triple of this berserk technique, he still only comprehended the first one, the second and third layers, although he would also cultivate seriously when he had time, but it was not that simple.

Of course, he had a feeling that he was not far from learning the second level of the berserk technique, but it still took some time, Xu Xuan had never used this unique method that Liuyue had taught him, and he also regarded him as one of his killer skills, and now, it seemed that this time had come.

By blocking the black python before, he understood that his strength should not be too different from the strength of the black python, and now through the first weight of this berserk technique, he must be able to make up for this gap.
