However, the Black Snake is still an old fry who has been living in the world for decades. When facing Xingyuan's unexpected attack, Demon Moon Slash, after a brief surprise, he immediately released the yin energy to surround himself as a protection. Then the snake's scales were closed tightly. If he still used the trick of facing the collapsed mountain strike last time, one was that there was not enough time, and the other was that Xingyuan's attack was completely different from the collapsed mountain strike. The same trick could not face two attacks.

The black snake's snake scales were as hard as steel. Xingyuan slashed over with a knife and made a "clang" sound again. This time the black snake was not so lucky. After relaxing its guard, Xingyuan slashed a wound and was immediately pulled out of its body. The black snake suddenly looked up at Xingyuan. The snake's eyes were constricted and bloodshot.

At the critical moment, Xingyuan kicked the black snake's abdomen again, and gave the black snake a hand, so that the black snake could retreat faster.

Xingyuan was thrusting with a carp and instantly caught up with the backward black snake. Since he wanted to attack, he could not give the other party any chance.

Seeing Xingyuan chasing him, the black snake's face was unstable. After walking in the world for so many years, he was plotted against by a young boy. But then he thought, how could his ultimate cold air fail? This made the black snake puzzled.

At this moment, Xingyuan had already caught up with him, so he should settle this not-so-simple boy first.

"Bone-eroding venom!!"

Seeing Xingyuan that was about to catch up with, the black snake shouted, and then exposed two large poisonous fangs. Venom suddenly spewed out from the poisonous fangs, whistling towards Xingyuan with strong corrosiveness.

Halfway through, Xingyuan was just about to use the demon sword to block the venom, but after a kick, Xingyuan felt that the venom was not that simple. If he used the demon sword to block it, even if the demon sword ignored the corrosive power, if it splashed a little to him, it would probably be very troublesome.

Then Xingyuan forced the demon sword into the ground, turned his right arm violently, stepped on the ground with both feet, and forced the direction of his body to fly to the other side. Venom happened to pass by Xingyuan's face, and he almost avoided the black snake's venom spray. Xingyuan didn't expect that the black snake would actually have such a hidden weapon-like attack.

Xingyuan stopped and looked at the black snake that had stopped, with murderous aura in his eyes.

Xingyuan and Black Snake stood opposite each other, and their eyes were filled with strong murderous intent.

The Black Snake really felt that he had underestimated Xingyuan. His unique skills would actually be ineffective against Xingyuan. Seeing Xingyuan's current lively look, he was not in the slightest cold air, which really surprised the Black Snake.

Xingyuan was in the same mood. The black snake was impeccable in both offense and defense. He had not gained any benefits in the past few rounds of fighting with the black snake. If he had not developed martial arts, he would have been a cold corpse at this moment. The black snake's extreme cold air was indeed powerful. If Xingyuan had not protected his martial arts, he would have really couldn't think of any way to deal with the cold air.

Now, both of them have put each other on the list of killings, and the situation is like a feeling of either you die or I die.

Xing Yuan looked at the Black Snake coldly and did not rush to take action. The Black Snake had a higher cultivation level than him, and there was no benefit in fighting hard. Besides, there was still cold in his body. Although he was suppressed by the martial arts, it was still a hidden danger.

The Black Snake didn't dare to do it easily, and Xingyuan's toughness was beyond his imagination.

Seeing the black snake, he didn't dare to take action easily. Xingyuan thought to himself that his chance had come. Since just now, Xingyuan has always wanted to use the Demon Xingjiu Palace, but the Black Snake is already reluctant to leave. It is very close to Xingyuan and has no space or time to cast the Demon Xingjiu Palace. Now this opportunity is excellent.

Xingyuan didn't waste time, and immediately began to activate the demonic energy, preparing to use the biggest killer move of the Demon Xing Nine Palaces.

The Nine Palaces of Demon Walking are based on the Demon Sword. People who hold the Demon Sword rely on their own demonic energy to activate the nine demon souls sealed in the Demon Sword.

The sword of Demon Sword is an ancient artifact. Although Xingyuan doesn’t know who the first master of Demon Sword was, he thinks he is definitely a person with a good cultivation level. The magic trick of Demon Xing Nine Palaces was also developed by the first master.

Each palace in the demon sword is an ancient demon soul. To be precise, it is an ancient demon soul that has been enslaved. There are a total of nine demon souls. If the person holding the demon sword can be summoned, then these demon souls can be used by themselves.

Although it doesn't seem very powerful, if you think about it carefully, if anyone can directly summon nine ancient demon souls to cooperate with his own battle, and each demon soul is one of the most powerful demon souls in ancient times, that scene is really terrifying.

According to Gu Ze, at most he only summoned the six palaces, and the last three palaces could not be summoned no matter what. It is conceivable that even Gu Ze could not do it. It is so difficult for this demon walking nine palaces to practice to the extreme.

Xingyuan now forces the first palace to summon the first palace. If he can be successfully summoned, then the battle will be judged immediately. Not to mention the second-level black snake, a demon transformed into a demon, even if it is a peak demon transformed into a demon, the first palace of the Nine Palaces of the Demon can be evenly matched.

Although the Nine Palaces of Demon Xing Jiu is an extremely powerful and evil magic, the conditions for summoning are also very difficult. The depleted demonic energy and the requirements for the demonic energy level make people only look at the plums to quench their thirst.

Except for the first palace, the demonic energy does not require demonic energy. From the second palace to the third palace, the demonic energy required is the yellow-level demonic energy, the fourth palace to the sixth palace requires the mysterious-level demonic energy, while the seventh palace to the eighth palace requires the earth-level demonic energy, the last level and the most difficult level. The last palace of the demonic energy in the nine palaces requires demonic energy to reach the heaven level, otherwise it would be impossible to summon the last demonic soul of the heaven-level level.

The demonic energy is just the preliminary condition for summoning the demons and walking on the Nine Palaces. It is even more harsh on the physical conditions, will, and self-cultivation of the sword holder.

In short, it is even more difficult to summon the Nine Palaces of Demons in full.

Now all the Xingyuan summons the first house at the entry level, and does not require the level of demonic energy. Relatively speaking, it is a very simple palace, but the depleted demonic energy is beyond Xingyuan's imagination.

Xingyuan penetrated all the demonic energy into the demonic sword, and then his mind also passed through his arms to the demonic sword. He and the demonic sword instantly became one. At this time, Xingyuan had already merged with the demonic sword and the man sword, and reached a wonderful state. Xingyuan found that he seemed to be a demonic sword, and the demonic sword was himself.

In the state of Xingyuan, the surroundings began to tremble slowly, the trees began to shake violently, and the small stones on the ground seemed to be about to rise into the air. These originally lifeless objects seemed to be afraid of something and dared not stay where they were, wanting to escape.

Seeing this strange phenomenon, the black snake naturally felt that the Star Abyss was extremely strange. When it became fierce in its eyes, the black snake instantly began to condense its demonic aura and curled up the snake's body. The black snake actually began to slowly rise into the air. From a distance, it looked like a full moon.
