As Billy spoke, he released his spiritual power to probe the opponent’s cultivation, but there was no fluctuation in aura.
If it wasn’t deliberately concealed martial aura, then at least it was the late stage of Controlled Kun Realm, or even Mystic Kun Realm!
So strong!
“Whatever, call me whatever makes you happy!” Greta also smiled.
“Then I’ll still call you Greta!” Billy smiled lightly. “It’s easier to say!”
“Okay!” Greta responded.
“Are you alright now?” Billy asked.
“My physical body is fine, but my soul still needs some time to recover!” Greta nodded.
“Your soul isn’t healed yet?” Billy couldn’t help but ask.
He was waiting for her to teach him how to comprehend the Heaven Book. If her soul wasn’t healed, did that mean he had to wait?
“Yes!” Greta nodded and added, “But don’t worry, although it’s not fully healed, I can already comprehend the Heaven Book!”
“Oh?” Billy’s eyes lit up slightly.
After saying that, as if remembering something, he continued, “I need to apologize for something…”
“Did you kill Curtis Wade?” Greta interrupted him.
“You know?” Billy was slightly stunned.
“I guessed!” Greta responded. “If he couldn’t find me, he would definitely look for you, and with your personality, you would definitely take action!”
Am I that violent?
“You knew I would have a fight with him, weren’t you worried he would kill me?” Billy asked.
“If you were that easy to kill, you would have died countless times already, wouldn’t you?” Greta smiled.
“Aren’t you overestimating me?” Billy responded.
“Even if the Nine Dragons Cauldron doesn’t help you, as far as I know, the Heavenly Xuan Array Compass should be with you, right?” Greta said.
“With your combat power and the Heavenly Xuan Array Compass, Curtis Wade couldn’t possibly be your match…”
“You don’t blame me?” Billy asked.
“Why would I blame you?” Greta smiled. “You helped me get rid of an annoying fly without me having to bear any infamy. I should be thanking you!”
“Alright then!” Billy shrugged.
Why did it feel like he was being used by Greta?
“Anyway, thank you!” Greta bowed to Billy.
After a slight pause, she continued, “Wait here for a while. I need to handle something first. When I return, I’ll teach you how to comprehend the Heaven Book.”
“Can I ask what your current cultivation level is?” Billy asked curiously.
“I can only tell you that if the Nine Dragons Cauldron doesn’t help you, even if you use all your trump cards, you won’t be my match.” Greta smiled.
After saying that, she flew away.
“So strong?” Billy couldn’t help but say.
Greta was gone for two whole days.
Two days later, Greta returned to the small courtyard.
Then, she asked Billy to take out the Heaven Book from the Celestial Pavilion and began teaching him how to comprehend it.
Only then did Billy understand why Greta said last time in the Celestial Pavilion that copying the Heaven Book was useless!
Because comprehending the Heaven Book wasn’t about reading it!
It required one’s soul to leave the body and merge into the Foldspace within the Heaven Book!
The text and patterns on the Heaven Book were merely guides to enter the space.
Therefore, copying the Heaven Book was useless; the Foldspace of the Heaven Book couldn’t be copied!
Thinking back to when he had everyone copy the Heaven Book in the seventh-tier star domain to study it later, it seemed generous but was actually useless. His mouth twitched at the thought!
In other words, even if someone understood all the text and patterns, they would only know how to enter the ‘Heaven Book Foldspace.’
Without the Heaven Book as a medium, just knowing how to enter was useless!
Of course, even this first step was hard. Without guidance, even projecting one’s soul onto the Heaven Book wouldn’t allow entry into its space.
“Is this the Foldspace of the Heaven Book?”
Soon, under Greta’s guidance, they entered a strange environment.
It looked like a massive library with a vast area filled with chaotic bookshelves packed with countless books.
Each bookshelf was very tall. When Billy looked up, the tops of the shelves were shrouded in mist, making it impossible to see the end.
Billy felt like his soul in this place was as insignificant as a speck of dust in a vast ocean.
Moreover, the oppressive atmosphere here was terrifying. Billy felt like his soul could dissipate at any moment.
He finally understood why Greta said a month ago that they had to wait for her soul to heal before she could bring him here to comprehend the Heaven Book.
If one’s soul was severely damaged and they recklessly entered here, it would only make things worse.
“Yes!” Greta nodded. “This volume of the Heaven Book is the second volume, so we are now on the second floor of the Tower of Heaven Book!”
“The Tower of Heaven Book?” Billy was stunned.
“Yes!” Greta nodded.
“There are nine volumes of the Heaven Book corresponding to nine floors of the Tower of Heaven Book. Each volume of the Heaven Book is equivalent to a key for each floor.”
“The Tower of Heaven Book has ten floors. If you can gather all nine volumes of the Heaven Book, you can reach the top floor!”
“Really?” Billy was stunned again.
As he spoke, he thought of the Heaven Book Miss Fairy gave him. He wondered if it was the key to the first floor.
“Can we go directly from this second floor to the third floor?” Billy continued to ask.
“Unless you have the third volume of the Heaven Book!” Greta responded.
After saying that, she added, “The Heaven Book you got in the seventh-tier star domain is the key to the first floor, so you can also check out the first floor!”
“How do you know my Heaven Book is the key to the first floor?” Billy asked curiously.
“That volume of the Heaven Book came from the eighth-tier star domain.” Greta responded.
“A strong person obtained that volume of the Heaven Book and was besieged. Although he killed everyone in the end, he was seriously injured.”
“He knew staying in the eighth-tier star domain meant certain death, so he fled to the seventh-tier star domain.”
“But shortly after arriving in the seventh-tier star domain, he fell.”
“I see!” Billy paused and then asked again, “Is it true that each volume of the Heaven Book contains a supreme martial skill?”
“You think too much!” Greta said. “The true supreme martial skill is only one set that requires gathering all nine volumes of the Heaven Book and reaching the top floor to obtain!”
“Really?” Billy was slightly stunned. “Then what’s in each volume of the Heaven Book?”
It seemed that rumors were not trustworthy!
He always thought each volume of the Heaven Book contained an unparalleled technique!
“I only know that there are indeed techniques in the first three floors, but they are not supreme!” Greta responded. “However, if comprehended, they are still quite beneficial.”
“As for what’s above the fourth floor, I don’t know. There are no rumors about this in the eighth-tier star domain; probably no one has ever entered.”
“What technique is on this floor?” Billy couldn’t help but ask.
