On this day, when Kong Fei came here again with a pot of wine and as usual, the old man who usually squinted in the sun on the chaise longue had just come out of the scripture building, holding a black wooden box half the size of a palm.

Seeing Kong Fei here, the old man was not surprised, but glanced at Kong Fei meaningfully, and said with a smile, "That's it, I won't drink today, come, I'll show you something good!"

The old man said, leading Kong Fei towards the stone cave behind the scripture building.

The stone cave in front of you is not big, it looks dry and tidy, except for a stone bed, a stone table, and two stone benches, there is nothing else in the whole stone cave, here, it is also the place where the old man rests on weekdays.

As the old man came to the stone cave, Kong Fei obviously thought of something at this moment, and the old face of the original Gujing Wubo couldn't help but have a hint of anticipation.

"Senior, but there is a way to solve my problem?"

Kong Fei couldn't help but ask, but when he heard Kong Fei's words, the eyes of this usually somewhat unobtrusive old man revealed a trace of strangeness, and after staring at Kong Fei for a long time, he smiled and said, "The solution is in this box, but whether you have this opportunity or not, it still depends on the will of heaven!"

After speaking, he no longer looked at Kong Fei, but solemnly placed the black wooden box in his hand on the stone table, and then with a wave of his sleeve, a ray of light appeared in the entire cave out of thin air.

Seeing this old man so solemn, Kong Fei's eyes flashed a little thought, and even the expectation on his original face was quietly hidden, but there was a faint hint of hesitation.

Of course, at this moment, all his attention fell on the wooden box in front of him, and the old man naturally didn't see the change in Kong Fei's expression.

After doing all this, the old man's hands suddenly pinched out the strange seals of the Dao Dao, and with the continuous change of the handprints, the originally ordinary wooden box suddenly glowed with a layer of ghostly light, and the countless runes on it seemed to come to life, rearranging them at an extremely fast speed according to some strange trajectory.

Kong Fei quietly looked at the scene in front of him, without the slightest look on his face, only occasionally glancing at the old man's gaze with a faint hint of inquiry.

After a full cup of tea, as the old man gently spit out a word, a drop of blood suddenly oozed from between the originally dry fingers, and as the old man gently touched the wooden box, the originally black wooden box suddenly turned bloody, and at the same time, a machine-like "click" sounded, and the wooden box opened in response.

In the wooden box, a jade slip that was pitch black and about the length of an index finger lay quietly in it.

"Do you know the origin of this jade slip?"

Holding the jade slip in his hand and playing with it for a while, the old man suddenly opened his mouth to ask, but before Kong Fei could respond, the old man muttered to himself, "Thirty thousand years ago, the Great Tribulation of Heaven and Earth, the creatures of the Demon Domain invaded the land of the Demon Continent, and our Yin Demon Hall was inherited at that time, but you may not know that the first hall master of our Yin Demon Hall is actually a veritable demon realm creature!"

The old man's words stunned Kong Fei's words, no matter what, Kong Fei didn't expect that this Yin Demon Hall would actually be established by the original demon realm creatures.

"Later, for some reason, the first hall master was chased and killed by the creatures of the demon world, in order not to harm the Yin Demon Palace, the hall master could only escape alone, and this jade slip was left by the hall master before leaving. ”

After speaking, he directly threw the jade slip to Kong Fei, and subconsciously took it in his hand, Kong Fei's eyes raised slightly, and he looked at the old man in front of him with some doubts.

"Since you are born with a demon bone, you are naturally different from ordinary people, if you can detect the things in the jade slip, maybe you can solve the problem on your body. ”

The old man said indifferently, and after speaking, he signaled to try it quickly, seeing this, Kong Fei pondered for a moment, and he couldn't see the slightest expression on his face, but according to what the old man said, he put the jade slip on his eyebrows, and the power of divine thoughts surged out and poured towards the jade slip.

For what the old man said, Kong Fei only believed two points at most in his heart, judging from the old man's attitude towards this jade slip, this jade slip was obviously extremely precious, he was not related to this old man, only a few times of drinking, this old man was willing to take out such a valuable thing to let himself understand, obviously a little unreasonable, not to mention that the old man in front of him occasionally looked at him in his gaze, although he tried his best to hide, but Kong Fei still spied a trace of expectation from it.

This made Kong Fei very strange, what did this old man expect from himself? Could he expect that he would be able to comprehend the things in the jade slip?

Confused, Kong Fei simply didn't think about it anymore, his divine thoughts invaded, and sure enough, there was nothing else in the jade slip except for an elusive gray energy compartment.

Cautiously probed with the power of divine thoughts, but found that this energy compartment was very strange, not only could it isolate any form of prying eyes, but even the fluctuations that the energy itself should exist could not be detected at all, according to Kong Fei's previous experience, there were only two possibilities for this situation:

First, this gray light cluster is not composed of energy at all, because no matter what form of energy, there must be fluctuations in itself, and with fluctuations, this kind of airtight energy compartment can be constituted.

The second is that the energy level of this energy compartment is too high, and with his current strength, he can't detect the fluctuations in it at all, if this is the case, this energy compartment is probably not a thing in this realm, that is to say, it may be the upper realm, or something handed down from the demon realm.

This kind of speculation flashed in Kong Fei's mind, no matter what the situation is, it is not something that he can spy on at the moment, thinking of this, Kong Fei not only did not feel lost in his heart, but was greatly relieved, and was just about to withdraw his divine thoughts, and the next moment, something surprising happened.

The "Rune Sword Fetus", which was originally hidden in the depths of his soul and had not yet condensed and formed the rune starlight, seemed to be attracted by the things here, and directly attached to the Purple Mansion and entered the jade slip.

As soon as this "rune sword fetus" appeared, it slashed towards the center of the jade slip, and the gray light that was about the size of a pigeon's egg was gently slashed away.

"Buzz ......"

The moment the two came into contact, the originally smelly and hard energy compartment suddenly tumbled violently, and then, those "rune sword fetuses" carrying Kong Fei's consciousness penetrated into the light cluster without hindrance, and at the same time, a ray of black light extended out from the inside of the light cluster, merging into Kong Fei's divine soul one by one.

In a flash of light, a series of actions were completed.

In the outside world, Kong Fei's old face turned white suddenly, and when he opened his mouth, he spurted out a puff of donated blood, and his eyebrows and jade slips subconsciously came out of his hand.

Seeing this, the old man's face changed, and he immediately took the jade slip into his hand, and at the same time separated a wisp of divine sense, and probed towards the jade slip, when he noticed that the gray light cluster in the jade slip was the same as before, the old man breathed a sigh of relief at the same time, and faintly felt a little disappointed.

"What's wrong? What have you found?"

When Kong Fei was a little better, the old man couldn't help frowning and asked, hearing this, Kong Fei smiled bitterly and shook his head, "That light group is too tough, I wanted to forcibly infiltrate it with the power of divine thoughts, but I was injured by the shock of that light group, which disappointed my seniors!"

It seemed that he had expected this result, and the old man didn't show much disappointment on his face, but when he heard Kong Fei's later sentence, he couldn't help but sneer, "Hmph, it was forcibly infiltrated, do you know that the gray light cluster is not a thing of this realm at all, even if your strength is increased by ten thousand times, it is impossible to forcibly break through that barrier!"

After speaking, he waved his hand with some interest, "Go back and have a good rest, as for the problem on your body, if you want to solve it completely, there is only one way now, find a body to take away, if you succeed in the future, it will be considered a lot of creation." ”

As soon as the words fell, with a wave of his sleeve, the entire cave was cleared, and the prohibitions that had originally fallen around suddenly disappeared.

After bidding farewell to the old man, Kong Fei galloped all the way towards the residence, just entered the house, waved his hand and played a prohibition, completely sealing the whole house, and at the same time hurriedly sat cross-legged, his mind was introverted, and in the sea of knowledge, the five big characters of the "Yuan Shi Zhen Demon Sutra" were clearly rubbed in the depths of consciousness.
