Since the departure of the refining instrument peak, Yu Xinghai did not go back to the Xinghai stream directly, but went to the Gongfa Peak Gongfa Palace, and successfully entered it with the jade plate of Tianjiao's identity, and read the classics in it without time or number of times.

The purpose of his coming here this time was not to come for the exercises here, but to find the classics related to the Black Abyss Ghost.

Previously, he had asked Feng Chen and many sect disciples where the Black Abyss Ghost was where, but he received an answer that surprised him.

None of them had heard of such a place, so he had to come to the Gongfa Hall to look for it, to see if there were any relevant texts that recorded this place or similar places.

The jade slip left by the mysterious old woman to him, although it mentioned that the Soul Restoration Grass grew in the Black Abyss Ghost Snake and was accompanied by a topographic map, but because it was too one-sided, it was impossible to find such a small place in such a vast and vast primeval immortal domain.

However, he spent an afternoon and almost searched through all the classics in the Gongfa Palace, so it also attracted the attention of many disciples in it, but even so, in addition to seeing many immortal cultivators, he did not find the slightest record of the black abyss ghosts.

In desperation, he had no choice but to prepare to leave, stay for a while, and leave the sect to inquire elsewhere.

Just as he was about to leave, a golden light suddenly flashed in the corner of a dusty shelf.

The golden light flashed faintly and fleetingly, and if you didn't pay attention, you would think it was an illusion.

No, Yu Xinghai really thought it was an illusion, but after leaving, he felt that something was wrong, he felt that his mental state was very good, and there should not be such an outrageous thing as hallucinations.

So, under the surprise of the disciple on duty, he took out the Tianjiao jade card and walked in again, came to the corner of the dusty shelf, slowly squatted down, and reached into it for a while.

"What is this?"

Yu Xinghai took out a jet-black piece of metal from under him, with a sense of endless vicissitudes, and looked at it in shock.

After looking left and right for a while, and when he realized that no one was paying attention to him, he included the jet-black unknown metal piece in the fairy storage ring.

Then he hurriedly walked out of the Gongfa Palace, and when he was walking on the road, he took it out and put it in his hand and observed it.

It was an unknown piece of metal that exuded a hint of vicissitudes, and even if he was a person from the fairy world, he couldn't recognize what kind of material it was made of.

While I was in shock, I wiped the dust off it, and several ancient fonts appeared on the surface of the metal sheet.

These ancient fonts are not seals, but a more complex and ancient font.

In the fairy world, this font is called inscriptions, and he had studied inscriptions when he was in the fairy world, so he recognized the four characters on the unknown metal plates.

These four words are called 'Dan Dao Holy Scripture'!

The moment he recognized a few words of the Dan Dao Holy Codex, Yu Xinghai's heart suddenly floated with strong fluctuations, what can be called the Dan Dao is only the way of alchemy, and it is also known as the Holy Codex, plus the unknown metal piece exudes the vicissitudes of life, this thing must be extraordinary.

"Who put such an unknown piece of metal in the corner of the shelf, regardless of asking?" Yu Xinghai thought in his heart, and his divine sense couldn't help but glance over it.

However, the next moment he showed a strange look, and his divine sense swept over it, and he actually found that it was like a quagmire, and it actually disappeared.

"What is this, why doesn't it seem that even the divine sense can be imprinted?" Yu Xinghai was suddenly a little shocked, generally as a cultivation thing, the divine sense can imprint the imprint, but the thing in front of him cannot.

Immediately afterward, he tried many methods, but found that even if he tried to integrate the essence blood, the Dan Dao Holy Book in his hand did not react in the slightest.

In this way, he couldn't help but think of the thing left in the corner of the shelf, it is estimated that the ancestor of the sect collected this thing, and found that he couldn't uncover what was inside, and in the case of being reluctant to throw it away, he threw it on the shelf at will, and no one cared about it for a long time, and it was covered with dust when it fell.

But Yu Xinghai firmly believes that this thing is absolutely extraordinary, and it is definitely not a product of this era, which can be seen from the sense of vicissitudes it exudes, and he clearly saw it emitting a flash of golden light before, so he concluded so.

Such a mysterious object, instead of stopping his curiosity about it, became more and more interested, so he looked through it as he walked, hoping to study him thoroughly.

However, until he walked all the way back to Xinghai Stream, he failed to thoroughly study the unknown metal piece in his hand.

When Bu Shiren saw him with his head down, not looking at the road at all, but at a palm-sized black thing in his hand, slowly walking into the starry sea stream, he was immediately surprised.

At this time, Zi You stood on his shoulders, carrying a pair of small hands, and if he looked closely, he really had a bit of a fairy-like temperament, but it was a pity that it was too small.

These days, she has become accustomed to standing on the shoulders of several people like this, and as time goes by, she has not talked as much as she had at the beginning, and after seeing Yu Xinghai come back, she simply said hello.

Bu Shiren stared at the thing in his hand, with a burst of surprise in his eyes, he was able to study the other party so obsessively that he didn't even look at the road when he walked, although it was dark and there was nothing surprising about it, but he dared to conclude that it was definitely an extraordinary thing.

Subconsciously, he sniffed the air around him fiercely, and then a fine light flashed in his eyes.

"Phew, treasure... Brother Yu, what are you holding in your hand?"

As soon as his voice came out, Yu Xinghai was immediately interrupted, and a spiritual light flashed in the depths of his mind when he looked up, and his face suddenly became happy.

He tried many ways to open the metal piece of the Dan Dao Holy Book in his hand but did not open or recognize the master, such as seeing Bu Shiren, he couldn't help but think of a way to open it.

"Chubby, quick... Quick, you take a drop of essence blood for me, and I'll try this thing to get a reaction. He said to Bu Shiren with some excitement.

Bu Shiren is a descendant of the Chaos Demon God, and the essence blood in his body contains a trace of the blood of the Demon God, he feels that the things in his hand, with such a sense of vicissitudes, should be very old, just use the blood of the Demon God to try to see if it can be opened.

Bu Shiren didn't know what kind of medicine was sold in his gourd, and it seemed that he would conduct an experiment when he asked for his essence blood when he met, but Yu Xinghai's words were an order, and although he didn't know why, he still broke his fingers and forced out a trace of essence blood.

Yu Xinghai wrapped his spiritual power in essence blood and slowly approached the jet-black metal sheet, but he was very disappointed and didn't react at all.

"It's useless?" Suddenly, Yu Xinghai felt very deflated, what a tragic thing it was to have a treasure but not be able to get what was inside.

At this time, Zi You, who was standing on Bu Shiren's shoulder, tilted her little head, and between the fluttering hair, a trace of curiosity flashed in the depths of those small eyes.

"Big brother, what is the thing in your hand?" Ziyou tilted his head, opened his mouth to him curiously, and asked, "Can you show Ziyou?"

When Yu Xinghai heard this, he handed it to her casually, and he didn't think much about it, anyway, he couldn't open this Dan Dao Holy Scripture, so why not show her?

After Zi You took the unknown jet-black metal sheet with both hands, he hugged it beside him and observed it carefully, and the sound of surprise came from time to time.

"Phew, how do I feel like this thing can be opened?" Zi You couldn't help muttering to herself after holding the jet-black unknown metal piece for a while.

As soon as these words came out, Yu Xinghai was shocked, and eagerly opened his mouth to ask her, "Ziyou, what did you say, you said that you could open this Dan Dao Holy Scripture?"

After listening to his words, Ziyou lowered her head and thought for a while, then replied, "Hmm... I feel like I can, but I need to try it to find out!"

As soon as Ziyou said this, Yu Xinghai couldn't help but feel that his eyes lit up, and there was a hint of expectation between his expressions, he was out of luck, but if Ziyou could open this Dan Dao Holy Book that contained the vicissitudes of life, it would be a good thing.

At this time, Bu Shiren, who was standing not far away, suddenly felt a hot breath coming from Ziyou's body, and his face changed and he hurriedly retreated.

At the same time, Zi You's figure suddenly turned into a mini sea of light purple and dark red, enveloping all the palm-sized Dan Dao holy scriptures.

Yu Xinghai looked at Zi You's actions, his brows couldn't help frowning, and there was a little more worry in his expression, for fear that the scorching power contained in it would directly melt the unknown metal piece.

However, his worries were unnecessary, Zi You's hand was measured, and he couldn't melt it at all because he didn't know what to make of the material of the unknown metal piece.

The body of Zi Yu is a strange fire, so the unknown metal piece of the Dan Dao Holy Book is scorched by the purple and dark flames of the different fire, and a trace of golden light slowly flows on its surface.

The moment he saw the golden light, Yu Xinghai was overjoyed in his heart, this golden light was too familiar, he was attracted by this golden light before, and then he found this Dan Dao holy scripture.

Under the fierce burning of the Purple Shadow Flame, the golden light became more and more abundant, and finally emitted a dazzling golden glow, which made Yu Xinghai and Bu Shiren both cover their eyes with their hands.

When he moved away again, the golden glow had disappeared, and Zi Yu had regained his human form.

At this moment, her small hands were holding a thick golden book.

The book is the size of a normal book, except that both its writing and its pages are golden and sparkle in the sun.

Ziyou struggled to hold the golden book, flew in front of Yu Xinghai, and said, "Big brother, this book is so heavy, take it quickly..."

When Yu Xinghai heard this, he hurriedly took the golden book he was holding, and looked carefully, and there were still four words on it: 'Dan Dao Holy Scripture'.

However, these four words have now become four embossed words, and you can feel the bulging feel when you touch it lightly with your hand.

"Brother Yu, what the hell is this?" Bu Shiren leaned in at this time, glanced at the Dan Dao Holy Book in his hand, and couldn't help but ask him.

Yu Xinghai didn't answer, and gently turned the first page of the golden book, and what caught his eye was a passage written by an inscription.
