The iron book was heavy and a little cold, no matter how hard Tang Feng tried, it was just sitting there without moving.

When the students of the surrounding academies saw this, they all shouted: "I just said, this kid can't do it at all, just because he can open the iron book?"

"Since ancient times, no one has been able to read this book!"

"Get out of here, don't be embarrassed there!"

These students sneered one after another, probably because Tang Feng had stopped them just now, so they were full of hostility.

Tang Feng frowned, and the devouring black hole in the sea of dantian directly appeared, suspended above this iron book.

Immediately afterwards, the spirit element in his body surged out and rushed into the devouring black hole, and the entire black hole cyclone spun wildly in an instant.

For a while, the flying sand and rocks were surging, the sky and the earth were changing, and the formation was very large, and those academy disciples who were a little closer could not withstand the pressure of the momentum of devouring the black hole at all, and they all retreated backwards.

"What is this, so powerful?"

Leng Qingbo was shocked, he was a knowledgeable person in the end, and he could see at a glance that this black hole cyclone was far more terrifying than three thousand divine fires.

"This kid, it really can't be underestimated, this cyclone faintly, there is a trace of the taste of the law of the Great Dao in it. ”

Leng Qingbo secretly sighed in his heart, and at this time, he couldn't help but change his gaze when he looked at Tang Feng.

Because he knew very well, not to mention the three thousand divine kingdom techniques, but with this devouring black hole, Tang Feng was enough to be included in the list of Tianjiao.

Tang Feng didn't bother to pay attention to the reactions of the people around him, his hands pinched again and again, and the rotation speed of the devouring black hole above accelerated more and more.

"Devour!" Tang Feng exhaled, and in an instant, a terrifying devouring force rushed directly towards the iron book.

Before this devouring power had even completely landed, the entire square of the Heavenly Confucian Academy was already dark, and even the clouds on the heavenly dome were swallowed up by the rolling stirring.

The thick blocks of marble in the square have been shattered, the surrounding trees have been uprooted, and even the nearby academy wall has been destroyed.

Under the shroud of the devouring cyclone, it seems to be filled with an apocalyptic momentum.

"Who dares to be presumptuous at the gate of the academy?" Suddenly, with a cold cheer, four old men rose from the depths of the academy.

Looking at it like this, these four old guys should be the protectors of the academy or something.

"It's none of your business, I'm here. Leng Qingbo snorted, and then with a wave of his hand, a white shield swept out and wrapped the entire square.

With this white shield, the devouring power of the black hole cyclone was bound inside, and it could no longer break through the wanton destruction.

The four academy elders were suspended in the void and arched their hands: "It turns out that the Chief Sect Master is here, so don't bother us to worry about it." ”

"It turned out that someone was flipping through the iron book, so I said who was so bold and dared to make trouble in front of the door, but this little guy's movement seemed to be too big. ”

Bang......

At this moment, an earth-shattering bang suddenly erupted, and the devouring power of the black hole cyclone completely fell on the iron book.

The earth immediately stirred up the dust in the sky, directly blocking the iron book, making it impossible to see the movement inside for a while.

"How's it going, what's going on inside? Has the iron book been opened by this kid?"

At this time, the academy students who had already been hiding far away asked one after another.

"You ask me, I ask who to go, where can I see this kind of situation?"

The dust was too big to see, and because of the shield of the cold waves, they couldn't use some means to investigate.

At this time, Leng Qingbo shook his head and said with a smile: "This kid's methods are really good, but it seems that he is still almost able to open the iron book." ”

"No, not almost, but two or three points short!"

Cui Jinghao on the side asked, "Master Sect Chief, you said that, Tang Feng can't open the iron book?"

When he said this, the corners of Cui Jinghao's mouth rose slightly, but he was afraid that even he didn't know that Tang Feng's failure was a happy event for him.

"See for yourselves. ”

After Leng Qingbo finished speaking, he raised his hand again for a while, and the silver-white shield was removed, and the dust quickly dissipated.

At this time, everyone saw that the iron book, which looked vast and simple on the whole, was still sitting there intact.

Wow......

A burst of cheers suddenly erupted from the entrance of the entire academy, and of course most of these voices were made by the students of the academy.

For them, Tang Feng's defeat was like a victory for them.

"Great, the Iron Book is still there!" some of the students cried.

"I said a long time ago, with this kid, it is impossible to open the most valuable treasure of our academy!"

All the academy students present were cheering, but Tang Feng was frowning.

"It doesn't make sense, even a black hole cyclone can't swallow it up?" Tang Feng secretly sighed, this is the first time this phenomenon has occurred.

Leng Qingbo smiled at this time and said: "It doesn't matter if you can't open it, since ancient times, no one has ever been able to look at this iron book, maybe ......"

He paused when he said this, because the next words should not have been said by reason, but after thinking about it, he said: "Maybe this is not an iron book that can be opened." ”

Tang Feng shook his head and said: "Since it is a book, there is absolutely no reason why it cannot be opened, maybe my method is wrong." ”

Leng Qingbo originally wanted to say something, but when the words came to his mouth, he swallowed it back, since ancient times, how many Tianjiao disciples of the human race, even those Tianjiao of the demon clan, have tried a lot.

So far, almost all the methods have been used, but no one can open this book.

Tang Feng didn't say a word, he sealed his hands again, released three thousand divine fires, and rushed towards the iron book in front of him.

The golden flames burned brightly, directly enveloping the iron book completely.

Seeing this, the students of the academy shouted again: "Hey, I said that you kid, you actually set fire to it, if you burn the iron book of our academy, can you afford to pay for it?"

"That's it, if you can't open it, you can't open it, you kid get out of here!"

Leng Qingbo waved his hand and said with a smile: "It doesn't matter, if this iron book was really burned so easily, then it would have been destroyed more than 100,000 years ago." ”

Sure enough, no matter how the divine fire burned, this iron book still didn't change at all, and Tang Feng had to give up.

"Could it be that there is really no way to open it?" Tang Feng's brows furrowed tightly.

Leng Qingbo said: "Okay, let's stop here, since ancient times, how many Tianjiao can't do anything, it's not a shame that you can't open it." ”

Tang Feng had already thought of giving up, but at this moment, he thought of the Yin God in the Tianxin Palace.

"Perhaps, there's a way for this thing?"
