Chapter 359: Activation of the Dark Oath Book

"Strange, why hasn't Xiandumu Aye appeared?" Lingyun looked at the battlefield where the curtain had already fallen, his brows furrowing involuntarily.

With a casual wave of his hand, the Array set up here gradually dissipated, eventually vanishing completely.

"Lingyun, it seems something has happened; my memories regarding the Dark Oath Book are gone," Nangong Nayue suddenly said to Lingyun.

"Memories regarding the Dark Oath Book are gone?" Lingyun's brows furrowed slightly, and then he suddenly felt a peculiar fluctuation rising from afar; previously, due to the obstruction of the Array and the chaotic battlefield, he truly hadn't noticed this subtle fluctuation.

Lingyun turned his head to look in that direction: "Is that... Private Saikai Academy?"

"This fluctuation is? The Dark Oath Book?" Also sensing this familiar fluctuation, Nangong Nayue couldn't help but have her pupils constrict, and she spoke with a look of surprise.

"The Dark Oath Book?" Lingyun's expression sank, and then he actually laughed out loud: "A feint to the east while attacking in the west; as expected of Xiandumu Aye, truly a clever method. It seems Xiandumu Aye really went to great pains for this plan. I think that from the very beginning, when she activated the No. 014 Grimoire, she never expected it to be a complete success, but rather placed all her goals on the Dark Oath Book. Everything done afterward was merely to distract my attention; looking at it now, she succeeded."

"Oh no, if the power of the Dark Oath Book shrouds the entire Itogami Island, the whole island will fall into a crisis of sinking, and by then, things will be beyond redemption," Nangong Nayue said in alarm.

"Beyond redemption? It seems you still care quite a bit about Xiandumu Aye, Yuejiang!" Lingyun looked at Nangong Nayue and said with a playful expression.

"You, now is not the time to be saying that. If we don't stop Xiandumu Aye, things will be a huge mess," Nangong Nayue said with an anxious look.

"So you, the Vampire teacher, are in this place. Are these guys all criminals from the Prison Barrier?" Just at this moment, a spirited voice suddenly rang out.

Nangong Nayue turned her head to look; Kirasaka Sayaka was carrying Xiao Gucheng on her back, running toward their direction, and following behind her was Sentomoku Yuma.

"Kirasaka Sayaka, aren't you responsible for protecting La Folia? Why have you appeared here?" Nangong Nayue asked.

"You are, Nangong Nayue? Xiao Gucheng said you were in trouble, and I didn't believe it; I never thought you would have turned into this state!" Kirasaka Sayaka looked at Nangong Nayue with a look of astonishment. "After Her Highness the Princess helped me defeat the Meiya sisters, she left Itogami Island in a hurry, seemingly having some important business to attend to, so my escort mission was completed."

Just at this moment, Kirasaka Sayaka suddenly felt two chilling auras lock onto her simultaneously, causing her to shiver involuntarily.

"Don't worry, she is different from them," Lingyun suddenly said.

Hearing these words, Liuli and Luo Yexi simultaneously withdrew their killing intent, and only then did Kirasaka Sayaka let out a long breath. She had a premonition in her heart that if she had shown any sign of making a move just now, she would definitely have suffered a devastating blow in an instant.

"Xiao Gucheng, what happened here?" Lingyun looked at Xiao Gucheng, who was being carried on Kirasaka Sayaka's shoulder and had already fallen into a coma, his brows furrowing involuntarily.

"We were attacked by Xiandumu Aye. Xiandumu Aye used some unknown method to actually erase all the power on this bastard, and he was also severely wounded. Now Xuelai has been taken away by Xiandumu Aye," Kirasaka Sayaka's expression was very ugly. "Vampire teacher, do you have a way to save Xiao Gucheng?"

"To actually be able to erase the magic power on Xiao Gucheng, Aye definitely used the power of the Dark Oath Book," Nangong Nayue said with a serious expression. "The reason this island can stand upon this ocean is by relying on the power of magic. By borrowing the power of the Dark Oath Book, Aye can eliminate all Supernatural Ability powers on this Itogami Island; the consequence of doing this is that this island will be completely destroyed."

"There is actually such a thing? You're lying, right!" Kirasaka Sayaka said, somewhat absent-mindedly, "How could such power exist in this world."

"This is the power of the Dark Oath Book; otherwise, the Dark Oath Book wouldn't be called the most dangerous Grimoire in the world and be listed among the taboos," Nangong Nayue said. "Lingyun, we must act quickly, or it will be too late!"

"Wait, didn't you say the Dark Oath Book could erase Supernatural Ability powers? Why do you still say we can stop Xiandumu Aye? If we were to fight Xiandumu Aye purely with physical strength, it would be too dangerous," Kirasaka Sayaka asked with a puzzled look.

"Some things are better left unknown than known!" Lingyun replied indifferently.

"Liuli, you few are responsible for suppressing the expansion of the Dark Oath Book's power," Lingyun said to the others, while simultaneously tossing several Jade Pendants into their hands. "If you run into those guys again, just throw these things out; I don't mind leaving them without a corpse."

Luo Yexi and the others nodded slightly, then quickly left this place.

Seeing that Lingyun was also about to leave, Kirasaka Sayaka suddenly asked: "Um, Teacher Lingyun, Xiao Gucheng, is he still savable?"

"If you want to save Xiao Gucheng, the method lies with Sentomoku Yuma," Lingyun glanced at Sentomoku Yuma, who had been silent, and said slowly.

"The method lies with Youma?" Kirasaka Sayaka looked at the girl beside her with some astonishment.

Lingyun did not say anything more, and taking Nangong Nayue, he turned into a stream of light and disappeared into the horizon.

"I never thought Caihai Academy would actually become the center for the activation of the Dark Oath Book!" Nangong Nayue looked at Caihai Academy below, which was shrouded by a Barrier, and couldn't help but sigh.

In Nangong Nayue's eyes, every space within Caihai Academy was inscribed with complex magic runes. This was also Xiandumu Aye's special ability; as long as she knew the knowledge of a Grimoire, she could rely on her own ability to write out the magic runes within it and make it exert the full power of the original Grimoire.

Although the Dark Oath Book had been destroyed by Nangong Nayue ten years ago, Nangong Nayue had also read the Dark Oath Book, and the knowledge of the Dark Oath Book existed in her memory. This was the reason why Xiandumu Aye wanted to strip Nangong Nayue of her memories; as long as she obtained the knowledge of the Dark Oath Book, she could rely on her own ability to once again exert the might of the Dark Oath Book.

"Caihai Academy must be a place with special significance for you, Yuejiang," Lingyun said, looking at Caihai Academy, which had become the carrier for the Dark Oath Book.

"Yes, this place holds many of my memories!" A rare look of nostalgia appeared in Nangong Nayue's eyes. "By the way, Lingyun, can you really resist the power of the Dark Oath Book?"

"If the level of the Dark Oath Book were several times higher, perhaps I would truly have some misgivings, but if the Dark Oath Book only has this level, it cannot do anything to me!" Lingyun said, and taking Nangong Nayue, he flew downward.
