This place has put in a lot of effort to completely prevent the Tianxing chessboard.
Lu Yu observed carefully and found hundreds of formations, large and small, used to stabilize this floor and prevent the breath from escaping.
There is even a timing formation outside the door. If someone accidentally enters and has no way to get out, they will be automatically driven away by this formation.
However, now that Lu Yu has destroyed the Tianxing chessboard, this formation has naturally lost its meaning.
On the sixth floor, only one formation, the Star Chessboard, is placed, and no other book exercises are placed.
This is understandable. Except for Lu Yu, no one has the ability to crack the Tianxing chessboard easily.
In Jade Cauldron Academy, there are countless people who are proficient in formations. But if they take one look at this Tianxing chessboard, Kong Anping will feel dizzy and unable to solve it at all.
"The next step is the seventh floor."
Lu Yu looked at the end of the sixth floor. Behind it was the final secret of Tianshu Pavilion.
Rumor has it that there is a volume of the Heavenly Book handed down from ancient times in the Heavenly Book Pavilion.
But this is just a legend, no one has ever actually seen it. Only a few people can enter the second level, let alone the most mysterious seventh level.
There is only a wooden door blocking the space between the sixth and seventh floors.
Lu Yu gently pushed the wooden door open, but suddenly there was a violent tremor in the cave inside his body.
The magic power all over his body was suddenly out of control at this moment, and began to circulate rapidly and violently, as if he was casting some powerful spell.
Since Lu Yu has practiced until now, he has been extremely skilled in controlling himself, and his control of spiritual energy is even more exquisite to the extreme.
So much so that when other people see Lu Yu, they will think that he is a mortal who has never practiced cultivation.
But now, Lu Yu clearly felt that there seemed to be a tyrannical force inside his body that was no longer under his control.
Buzz——
A roaring sound suddenly echoed in the air around him.
In his cave, the Xuantian Sutra that had been silent suddenly trembled violently.
On it, countless words containing the profound and top secrets of the great road are suspended in the cave.
Lu Yu suddenly felt that there was a magic power in his body, running around everywhere, seemingly unable to suppress Xuantian Jing.
"What's going on?" Lu Yu had never encountered such a situation.
However, after all, he had rich experience, and he immediately thought that it was the existence behind the wooden door that caused the Xuantian Sutra to undergo such drastic changes.
"Suppress!" Lu Yu recited the Dao Sutra and circulated the magic power in his body over and over again, trying to completely suppress the Xuantian Sutra.
But Xuantian Jing, who used to be very gentle, seemed to be out of control and desperately wanted to escape from Lu Yu's control.
"There must be something hidden behind this wooden door!"
Lu Yu suppressed the mana that was constantly surging in his body, and directly pushed the wooden door open a gap.
Behind that is the seventh floor of Tianshu Pavilion.
It was still extremely empty inside, but within the tall and spacious hall, there was a page of densely packed scriptures suspended above it.
There is no longer any formation arranged here. The page of scripture is suspended quietly, faintly emitting a majestic golden light, making people afraid to pry.
Just like an emperor sitting in a lonely corner, even though he is in a miserable state, he still has a respected status.
Lu Yu here focused his consciousness on the page of golden scripture.
But after just one glance, Lu Yu suddenly felt a sharp sting in his eyes and quickly closed his eyes.
