【Birth Record: A zombie created by the first Demon King using the hero from the first Lamont family, because the Demon King thought it would be interesting for the head of the Lamont family to personally slaughter his descendants...】

【Material Drop: Hero Soul】

The information wasn't extensive, but Li Yue decided to chat with him more because of the "344%" predicted action success rate, to listen to the inner voice of the first hero—combining Isaac's identity as the first hero...the information gleaned from him would undoubtedly be a huge treasure.

Turns out the first hero was a big talker.

Li Yue didn't fully understand the "Weakness" column, guessing that Isaac's body stored too many hero souls. If he were to truly become his enemy, he should start from the angle of splitting the souls, which might offer a chance of victory.

The dropped material was also "Hero Soul"—Reedcott would definitely need this kind of material, and for Li Yue, if Isaac could really drop some souls one day, he wondered if the Bone Sword could directly manipulate them?

Analyzing this, Li Yue began to suspect that the numbering order within the Demon Encyclopedia, up to 100...was related to the birth time of these high-level demons—after all, Isaac was a demon created by the first Demon King, so ranking within the top 50 would be normal.

After reading the Birth Record, Li Yue found the first Demon King's amusement terrifying. First, Li Yue couldn't imagine how the grandchildren would feel meeting their grandfather personally killing them, and second, he couldn't imagine Isaac's state of mind when killing his own children and grandchildren...

"That hero, where did he come from?" Li Yue first asked about the swordsman, in order to better understand the overall situation of this world.

"Killed in the graveyard. He opposed demons and was called a hero." Isaac's answer was consistent with what he thought, and the logic was simple. He had never delved into the origin of that swordsman.

Incidentally, Isaac also supplemented Li Yue with the sentence "Don't go to the East" mentioned in Damon's notebook. Only then did Li Yue realize that the mysterious power from the East was so amazing, it was actually a graduation course of the "Death Ban"?

But Isaac didn't know any more than that. Li Yue decided to go back and ask Yingying and Dandan—they should have been present in that class.

"Why would you contribute the sacred object of the Isaac family?" This was the point that Li Yue had never understood—no matter what demon it was, there was no reason to offer it to a group of young demon children, especially a hero who had existed since the first Demon King. Why would he do something that seemed meaningless?

It was as incomprehensible as giving a gun to a brat.

Isaac curled his lips, still somewhat concerned about the lost treasure, but Li Yue heard the voice in his heart clearly.

【Mentor said...the demon children in this closed-door battle training...have the potential of a Demon King...】

Li Yue thought that there was indeed Mentor's shadow—since there was the influence of a Demon King tutor, it was definitely not a small matter.

"Could it be related to the future movements of Demon King City?" Li Yue asked again—what could Mentor interfere with, besides the growth of the demon children, the change of authority, the erosion of chaos...only this was left?

Li Yue still remembered that at the end of the closed-door battle training, the Demon King tutor would submit a report to the current city lord, which might decide whether Demon King City would open its gates.

If the city were to open, not only would a new demon expeditionary force be dispatched, but Demon King City would also have more interaction with human society—all of this would affect the future of the library, which was what Li Yue cared about.

【Mentor thinks...the demon children still need more growth...to cope with the possible...situation...in Demon King City...】

Isaac's inner voice also confirmed Li Yue's guess.

Possible situation in Demon King City? Does that mean Demon King City will open its gates?

Otherwise, why would they forcibly accelerate the growth of the demon children?

"The future of Demon King City has nothing to do with me, and it has nothing to do with you." From Isaac's own standpoint, whether Demon King City is open or not has little impact on him—anyway, except for the time of the closed-door battle training, this first hero freely enters and exits Demon King City, and has been active throughout the continent hunting heroes, with exclusive privileges.

"So...Mentor will advise the city lord to cautiously open the city?" Li Yue patted his holy whip belt, only asking the questions he cared about.

"I told you, it has nothing to do with you." Isaac said, but he couldn't completely hide his true thoughts.

【No...Mentor's suggestion...will be...Demon King City continuing to drift between chaos and reality...only...】

Li Yue almost asked "Only what?", but the completed blessing took effect and he swallowed it back, changing the question: "If Mentor advises to maintain the status quo, what will the city lord do?"

【The city lord is in recovery...but no one knows his true thoughts...Mentor speculates...even if he advises to maintain the status quo...he will still send a new round of demon expeditionary forces...】

Isaac's inner voice aroused a strong sense of crisis in Li Yue—although Li Yue hadn't figured out why...why the city lord was clearly weak but still wanted to launch an expedition, but this didn't prevent Li Yue from speculating about the situation in the most chaotic direction.

In other words, in the near future...Demon King City is likely to go to war with humans again?

How will the library deal with itself then?

Fortunately, since Li Yue came to Demon King City, a sense of unease had been lingering in his mind, and he had already strengthened the overall defense of the library—although it was not as strange as before Buddybog died, it was better at utilizing every bit of strength.

During this time, he needed to pay more attention to the atmosphere in Demon King City, perhaps a transformation was about to come.

"What to do is the city lord's business, you skeletons...just need to obey orders." Isaac reminded him, but he didn't know that Li Yue had nothing to do with the skeleton clan.

"That city lord..." Li Yue hadn't pried enough information from Isaac, but suddenly heard a hint of suspicion in his heart.

【This skeleton...can see through my thoughts?】

Isaac was, after all, a hero who had fought countless demons. Li Yue's targeted questions also aroused his suspicion, and he sized Li Yue up and down—had this annoying guy always had so many questions?

"That city lord...I wish him a speedy recovery." Li Yue took the opportunity to stop, immediately changing his words.

Anyway, he had also obtained an important piece of information—the city lord might send an expeditionary force, and Demon King City might return to reality.

While focusing on cultivating his own little plot of land in the library, Li Yue had not forgotten to pay attention to the situation, even if he could not yet tell whether this was good news or bad news.

Anyway, there was no seat for Brainlings in the demon expeditionary force...if a real fight broke out, the Blood Cocoon and the Forbidden Forest would be very busy, right? Would they be too busy to investigate the deaths of Bosch and Finley?

Li Yue thought casually, and was about to ask Isaac a few painless questions, pretending to be Scourge's innocence, but Isaac had already lost patience and only gave a reminder before leaving.

"This is the sacred object of the Lamont family. It is destined that it should end the bloodline of the Lamont family."

What's he talking about? Is he casting a spell with his words?

Li Yue didn't believe those mystical things at all, thinking that using it to clean up the Gnoll family was the right thing to do—whipping demons to death could be considered making the most of its use.

Such a long whip is just right for Yingying to use. As for when he can exert its power...he may have to wait until he turns it into a sensory object.

Isaac disappeared after stepping out of the door. Li Yue was thinking when he suddenly sensed the holy whip whipping the Bone Sword, and then the whip and the sword started fighting beside him.
