Yu Feifan didn't go to other places after leaving the Scripture Pavilion, Zhang Xiaotian found him, Yu Feifan didn't worry too much, instead of waiting for the person who attacked him behind the scenes, it was better to take the initiative to attack.

The only thing he's worried about now is Yu Xiaoxian, this girl often doesn't see anyone these days, and she doesn't know who she's dating.

After returning to the small courtyard, Yu Xiaoxian still did not come back, and Yu Feifan walked into the secret room alone.

Yu Feifan took out the somewhat worn exercise book he brought from the Scripture Pavilion, and after checking it over and over again, he didn't find anything special, and the words recorded on it were also jerky and difficult to understand.

"Demon Spirit Daoist, what's so strange about this book?" Yu Feifan pulled out the Heavenly Demon Sword behind his back, put it in front of his eyes and asked.

But after asking three times in a row, the demon spirit inside seemed to be asleep and did not speak. This made Yu Feifan feel a little helpless.

"Demon Spirit Daoist friend is not mistaken, there is nothing peculiar about this book. Yu Feifan pretended to sigh regretfully and said with some regret, "It's a pity that my bottle of 'True Qi Disperse'." ”

Yu Feifan had a look of chagrin after speaking, the books in the Hidden Scripture Pavilion were not allowed to be brought out, at most they copied a copy, Yu Feifan bribed the cunning and shrewd old man with a bottle of 'True Qi Dispersion' that had a miraculous effect on the true qi of the cultivators of the Acquired Realm.

Only then did he agree to put the transcription in its place, bringing out the original.

Yu Feifan kept sighing and regretting, and his words became more and more ugly, and he almost scolded.

"Don't be ignorant, you kid, this book is anything but ordinary. The demon spirit seemed to be unable to stand Yu Feifan's endless nagging and ridicule, and said in a loud voice with some anger.

"Why can't the juniors see it, and ask the demon spirit seniors for some advice. Yu Feifan was overjoyed when he heard the demon spirit's voice, and said with a respectful smile on his face.

"You kid don't use this set, and it's okay to give you a point, but it depends on the old man's mood. ”

"What do the Demon Spirit seniors need, just say it!" Yu Feifan's face was happy, and he pulled the Heavenly Demon Sword out of its scabbard.

"The old man is a little bored in this heavenly demon sword, if the Taoist friend has a successful cultivation, can he let the old man out. The demon spirit said in a low voice.

"Let my seniors come out, even if I have the heart, I can't do it. Yu Feifan's eyes flashed, and he seemed to say very casually, "Do seniors know what the black qi seal in the lower body is?"

"If you promise the old man something, I'll tell you, how?" The demon spirit seemed to see through Yu Feifan's mind and smiled faintly.

"Old fox!" Yu Feifan scolded secretly in his heart, still squeezing out a smile on his face: "Okay, as long as you have the ability to let the seniors out, you will definitely let the seniors get out of the Heavenly Demon Sword." ”

When the demon spirit heard Yu Feifan's words, he was silent for a while, as if he was thinking about the gains and losses.

"Okay, I'll help you kid. "The demon spirit has a decisive way.

"The seal in your body is a demonic aura. ”

"Demonic energy? There is really demonic energy in this realm, how can there be demonic energy in the lower body. Although Yu Feifan had some speculation in his heart, he still asked out loud.

"You should have heard of the Demon Gate in the North, although there are fewer true demons in this realm, it is not impossible. The demon spirit said leisurely, "As for the trace of demonic energy in your body, I think you should also know that it is transformed by the Heavenly Demon Sword." ”

"There is demonic energy in the Heavenly Demon Sword?"

"The Heavenly Demon Sword itself does not contain much demonic energy, but as long as the monk uses the Heavenly Demon Sword, it is bound to inject spiritual power into it. And every time the Heavenly Demon Sword was used, a trace of demonic energy would be generated into the monk's body. "The demon spirit is very cooperative.

"Come to think of it, you should also know that demonic energy and spiritual energy are incompatible, and this is the reason why the spiritual power in your body is sealed. Once the aura in the body can't suppress the demonic qi, the whole person will completely lose his mind. ”

"It's a bit impossible, those demon cultivators haven't made any crazy moves. Yu Feifan questioned.

"Hmph, how do you know the power of the Heavenly Demon Sword, as the demonic qi enters your body, there is still a trace of demonic thoughts, once the demonic qi gets out of control, you will become an existence that only knows how to kill and devour, and then you will become a real demon. The demon spirit said coldly.

Yu Feifan brought the Heavenly Demon Sword to his eyes, saw the lotus flowers used to seal it on it, and said, "What is the existence of the previous master of the Heavenly Demon Sword, and what is the origin of the Heavenly Demon Sword?"

This time, the demon spirit was completely silent and did not answer Yu Feifan's words, Yu Feifan called several times in a row, and the demon spirit said reluctantly: "You will know these in the future, and I won't tell you in the future." ”

Without waiting for Yu Feifan to speak, the demon spirit said impatiently: "Okay, I have already told you what I promised you, don't forget your promise." ”

"Senior, at least tell me what's so strange about this exercise, right?" Yu Feifan said helplessly.

"I don't know what's special about this exercise, I just feel a kind of aura on this book, and this book should be a book of inheritance. ”

"Inheritance books, what's so special?"

"This old man doesn't know anymore, a long time ago, monks would refine this kind of thing in order to pass on the secret inheritance of the Gongfa scriptures. Once the exercise is opened, the entire book will be reduced to ashes. And the form of inheritance is not confined to books. The demon spirit recalled, and said softly.

"Then how should this book be opened?" Yu Feifan said with a hint of anticipation.

"I don't know, every inheritance has its own fate. The demon spirit immediately said, which made Yu Feifan very speechless.

In desperation, he had no choice but to reseal the Heavenly Demon Sword into its scabbard, he had decided not to use the Heavenly Demon Sword lightly, he didn't want to become a person who could only kill.

Thinking about it, the death of his master Tianshui should have a lot to do with this sword.

The demon spirit seemed to see through Yu Feifan's mind and sneered: "What kind of existence is the Heavenly Demon Sword, once you let others know that the Heavenly Demon Sword is a hundred in your hands, you will also be killed." And don't think about discarding it from now on, the power of the Heavenly Demon Sword should also know that there is almost no existence in the world that can compete with it except for the Tianmu Sword. ”

Yu Feifan couldn't help but stop when he heard the hand that was putting in the Heavenly Demon Sword, his brows furrowed, and his eyes flickered. This person is right, is it really okay to abandon the Heavenly Demon Sword himself?

"For the sake of you and me, I'll help you again, here's a mantra that can help you resolve the demonic energy of the Heavenly Demon Sword. I hope that Daoyou can really keep his promise and release the old man completely after successful cultivation. The demon spirit suddenly said lightly.

Before Yu Feifan could think about it, a black qi flew out from the Heavenly Demon Sword, and after it kept flickering in front of him, a text was formed, which seemed to be an exercise.

After Yu Feifan silently recited, the black qi immediately dissipated.

"Magic Trick!" Yu Feifan recited silently in a low voice, his face was serious, as if he was savoring the content of the exercises.

"Hehe, boy, how can the old man's advantage be so easy to take advantage of. Once the demonic qi is refined, sooner or later it will be completely controlled by the old man. Forget it, let's sleep for a while after using the power of the True Yuan just now. The demon spirit in the Heavenly Demon Sword smiled gloomily, as cunning and cruel as an old fox.
