"Let them in!" Suddenly, a distant voice came from a long distance behind the guardians.

When Wang Yin heard it, this voice was the voice he heard before crossing the sea of blood, the voice that had been talking for a long time, and you finally came.

"Let's go!" Wang Yin walked towards the voice, Tianyou and the others followed, and the guards shook their bodies to stop them, but after all, they didn't make a move.

What is surprising is that when Wang Yin, Tianyou and the others walked forward, the scene in this ancient castle changed drastically, and the guardian and the high platform were gone, as if the group suddenly changed time and space and came to another dimension.

A kind old man appeared in front of everyone, and the scene in front of everyone slowly became as clear as an ink painting.

"You are the Great Demon King?" Wang Yin felt that this old man was a little happy, this is the Great Demon King's deity?

"Yes, I should be!" the old man smiled and nodded.

"What should it be! Aren't you still unsure!" Tianyou and the others looked at each other, just kidding, how could there be such a two great demon kings?

"Actually, I am a trace of the Great Demon King's divine thoughts, including the generals you met before, all of them are the divine thoughts of the Great Demon King!"

"It turns out that you are all Great Demon Kings!" Tianyou looked stunned in surprise.

"That's right!" the old man smiled slightly, "The Great Demon King has actually been sleeping, but the Divine Mind has always guarded his body. He sees all the so-called trials, so the people I choose are the ones chosen by the Great Demon King!"

"So what?"

"Are you wondering why that guardian didn't let you take ten heart books?" the old man didn't answer directly, but asked Wang Yin and the others a question.

"Just because he's not the Great Demon King's divine clone!" Without waiting for Wang Yin and the others to answer, the old man replied on his own.

"In other words, his standards are not the same as those of the Great Demon King!" Wang Yin immediately captured the key point.

"Exactly!"

"So what the Great Demon King means is that I can get these ten heart books?" asked Wang Yin.

"That's right, but before you take these ten heart books, I need to remind you of a key point!" the old man grinned, his face suddenly becoming serious.

"Reminder?"

"Yes!" the old man said with a straight face, "What is your Dao Heart Book, this is not for ordinary people to see! Ordinary people may not be able to see the content of the Heart Book at all, this is not a problem, maybe it is a good thing." But for those who can read the contents of the heart's letter, it can be a very risky thing!"

"Very risky!" Wang Yin raised his eyebrows slightly.

"Yes, the book of the heart is not something that ordinary people can read! People who are not great wisdom, great perseverance, and great fortune cannot read it! And the book of the heart is different from the general martial arts cheats, the general martial arts cheats are two books, but it is two and one, but the heart book is not! The pressure of the two heart books is definitely not as simple as the sum of numbers, let alone three, four, or even ten!" The old man looked at Wang Yin seriously, "In this way, are you sure you must read it?"

"Of course!" Wang Yin smiled slightly, there is no need to hesitate, he is here for the book of the heart, what is the hard work of trying to test without reading the book of the heart? As for the danger, he has even seen the king's spirit beast,

"Okay, in that case, it's your own choice, I hope you won't regret it!" the old man nodded slowly, "Follow me!"

The group walked silently, no one spoke, and the atmosphere was extremely solemn. Lewen

Eventually, the old man stopped in front of an altar-like stone platform.

The altar resembles a flattened mushroom, but the whole body is transparent, as if it was carved out of hedron, and it is still the best hedron of that kind.

"You sit down!" the old man motioned to Wang Yin.

"What is this?" asked Tianyou.

"This is Sitiantai!" replied the old man calmly.

"Brother Wang...... Be careful!" Tianyou and the others suddenly became worried, always feeling as if there was a net they couldn't see enveloping them.

Originally, what Tianyou wanted to say was Brother Wang, you should think twice, so let's think about it again, but when the words came to my mouth, I thought that Wang Yin came here for the trial, and now it seems very rude to persuade him to give up, so he changed his words.

"Don't worry!" Wang Yin confidently sat on the rooftop of Si Tiantai.

"Calm down!" the old man's voice was calm and steady.

Wang Yin did so.

Suddenly, the entire sky began to darken, as if it was quickly covered by a layer of black mist.

The black mist enveloped Tianyou and the others, enveloped the old man, and enveloped everything around him.

In the darkness, a silver-white heart book lit up, these heart books floated in the air around Wang Yin, when Wang Yin's eyes turned to which one, this book would turn golden, and then turn the pages on it.

"These heart books are different from what I saw in the Boat King family before!" Wang Yin said secretly in his heart, he also understood that the heart books he saw in the ship king family before were probably only copies of these heart books here, and these in front of him were the origin.

Just which one to start with?

Wang Yin's eyes wandered, and he suddenly saw one of them that made him feel very familiar, "This is probably the mother book of the first heart book I saw in the captain's family." Why don't you start here?"

In the past, Wang Yin drove the change of the heart book by sending out the mental power, but now it is different, this heart book does not need Wang Yin to activate the mental power to have countless changes, but these changes are not disorderly, but through the turning of the page, Wang Yin can turn the page or turn back through the gaze of the eyes.

The first few hundred pages of this heart book, Wang Yin has already read it in the boat king family, here is just a review, there is no pressure at all, and the new changes later, Wang Yin needs to start learning again, but for him, it is also a piece of cake, and there is no need to worry about it at all.

"So fast?" Outside of Wang Yin's body, the old man kept staring at him nervously, there was no black fog here, there was no shining heart book, and even in the eyes of Tianyou and the others, there was nothing here.

But the old man seemed to be able to see the heart book that Wang Yin was looking at, and even the speed at which Wang Yin turned the book, and this speed had already shocked him.

It is normal for ordinary people to read books word by word, those who can look at a line are masters, and those who can look at a line are called geniuses, but Wang Yin is faster than a genius, he is a direct page.

Others don't know, the old man is the doppelganger of the Great Demon King, so he naturally knows it clearly, the changes on the painting on this heart book are endless, a page of paper is not equal to a page at all, to put it a little exaggeratedly, a page of the heart book may be equivalent to an ordinary martial arts cheats - and it is the kind of cheats that are at least hundreds of pages.

And the young man in front of him can actually learn a martial arts cheats at a glance?

As for saying that this young man is bluffing, the old man absolutely disagrees, and he does not set a deadline, how can Wang Yin swallow dates in order to catch up with the schedule, and do not seek any explanation?

It can only show that the young man in front of him is indeed a genius.
