I Became the Mentor of the Weakest Demon King

### Chapter 272

Having safely obtained the permit, Nahun was able to reach Hell without any issues. Unlike when he had just crossed through the Gate, this place felt like the very beginning of Hell.

If one followed this path, which looked like a small branch, they would arrive at the central trunk of a tree. That was the Tree of Evil, Klifirot. This was the very place commonly referred to as Hell.

Surprisingly, there were many inhabitants of the Demon World at the entrance of Hell. That is to say, the demons. There were residents from the first layer, as well as those who had come for commerce. This was possible because this place, being the entrance to Hell, was merely a branch of Klifirot.

Dangerous Massu, strong demons, and spirits that cried out in pain every day did not exist here. Such things would only appear once one ventured into the larger branches.

Most merchants stayed in this area to conduct trade with the demons who came at the behest of the Great Ones, exchanging goods and receiving money.

No one dared to walk along those large branches.

“…Huh? Hey!”

“Hmm? Wait, where is that friend going?”

“If you go there, you’ll die!”

However, just coming over from the first layer, Nahun shoved his hands into his pockets and strode forward confidently. Seeing him walk as if he were in front of his own yard, several demons called out to him urgently.

“Stop! I said stop!”

But Nahun did not realize they were talking about him. It wasn’t that he was too foolish to understand; he simply did not perceive that their voices had grown urgent because of him. After all, unlike them, Nahun did not feel that this place was dangerous.

When someone shouts that there is danger on an ordinary street, they generally think it doesn’t concern them. Nahun stepped away from the small branches and moved forward.

And then….

“Kyyaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaak!!!!!!!!!!!!!!!!!!!!!!!”

“Dieeeeeeeeeeeeeeeeeeeeeeeee!!!!”

The spirits began to wail. Their cries echoed all the way to the small branches. Fortunately, Nahun hadn’t entered the larger branches yet, so he wouldn’t go mad from the spirits’ screams, but….

“This is bad…”

“Crazy, I told you not to go…”

“Haah, another one is going like that.”

People genuinely felt sorry for his demise. Spirits filled with unthinkable grudge began to stack up like a tower among themselves. In an instant, they climbed up to the branches, all the way to Nahun’s eyes.

“You too!!! With us!!!!!!!!!!!!!!!!!”

A scream that seemed like it would burst eardrums rang out, piercing the brain. If he were an ordinary person, his eardrums would have long since shattered, and he would have gone mad from that scream, mixing into the horde of spirits.

However, Nahun merely raised his eyes slightly without any reaction.

As his golden eyes gazed into the vacant pupils of the spirits, the spirit that was screaming at the top suddenly hesitated.

Nahun scolded that spirit easily.

“Shut up.”

“…Ah…ah??”

The spirit looked at him. It beheld the golden eyes staring at it.

Among the great entities that governed the Tree of Klifirot, it was the most powerful being.

It witnessed that.

“Go back.”

At Nahun’s brief scolding, the spirits reacted immediately.

“Kyaaaak!!!!! Kyaaaak!!!!”

“Kieeeeeeeeeek!!!”

As soon as they realized that, the spirits fled in fear. Despite being filled with grudges, typically unable to distinguish between a great demon and an ordinary demon, they recognized this man and felt a threat to their lives upon seeing him, running away.

He hadn’t shown any intent to kill. He had merely been annoyed by the noise and scolded them slightly, but with that alone, the spirits fled in terror. It took less than five seconds for the tower of spirits to collapse.

‘It’s nice and quiet now.’

Delighted by the quiet surrounding him, Nahun walked forward again. Meanwhile, the demons watching from behind were….

“……Wh, what?”

“The spirits retreated by themselves…?”

“They can’t even distinguish who the Great Ones are, and those guys are blocking the path…”

They couldn’t contain their astonishment. And among those who were lingering around the smaller branches for trade, some demons also….

“…What is that?”

“The spirits retreated on their own?”

“…Has there been a case like this aside from the Great Ones?”

“Taumiel wouldn’t have come out of the palace…”

Such a thing was possible only by one person in this Hell. The demons thought to themselves that they needed to inform their masters of this situation and hurriedly finished their transactions.

#

Unknowingly causing a great uproar, Nahun headed towards the Ninth Klifirot, Gamaliel. Though it might have been easier for Golraph to deal with her, there was a reason why he chose to go to Gamaliel instead.

‘Taumiel is most likely to have information.’

However, he didn’t know what would happen if he approached Taumiel directly, so he chose to go to Gamaliel, who was very close to her, that is, Lilith. Of course, this option had its risks as well….

“…If it’s her, I can overpower her.”

Even in a sealed state, he could handle someone like Lilith. She was a great demon that fell into the category of weaker ones, and two End-Time Massus were by Nahun’s side.

“Muung!”

“Pii!”

Perhaps because it had been a while since he returned to Hell, the two Massus revealed themselves without waiting for Nahun’s command. However, Nahun did not stop them.

After all, this was Hell. Unlike the Demon World, they didn’t need to hide their presence here. Watching the two Massus, who were excited to be back in a familiar place, Nahun smirked.

“I should have brought Leviathan too.”

“Muu, Muung!!”

It seemed Behemoth was saying that they could leave that one behind. Gize also chirped in agreement. Seeing that, Nahun chuckled.

“…It’s hard to tell if you two get along or not.”

“Muung?”

“Pii?”

Nahun moved along the branch connecting the Klifirots, the “Path.” The Klifirots were all intertwined organically, so even if one didn’t know the direction, eventually, if they kept going straight, they would arrive at their destination.

Due to memories sealed by the gold, Nahun could not recall the way to Gamaliel, but nonetheless, that was the reason why he walked aimlessly. He thought he would arrive eventually.

However, he wasn’t completely wandering around; he knew that Gamaliel was the Ninth Klifirot of Klifirot. In contrast, Nahun’s governing Klifirot, Nehemot, was the Tenth and the highest layer of Klifirot… so he assumed Gamaliel would be nearby as well.

Fortunately, he knew the direction to Nehemot, so he felt he could find Gamaliel’s location soon. As he walked with that mindset, a demon fluttered its wings and approached Nahun. It was a face he had never seen before. Thus, the Massus, who had been joyful, began to show their aggression and growled.

“Who are you?”

“Please do not be too wary, Great One. I am the guide sent by Gamaliel.”

“…Gamaliel?”

“That’s right, Great One. I will guide you along the fastest path.”

It seemed she had discerned his arrival almost eerily well. Setting aside how she had figured out Nahun’s visit, since he intended to go there anyway, it was a suggestion that wasn’t bad.

“Guide me.”

“It is my honor.”

Surprisingly, this demon, who was a subordinate of Lilith, did not have an unusual outfit and was quite normal. Considering the disgraceful attire of her master Lilith, it seemed she was not like that.

“Great One.”

“Hmm?”

“I am not permitted to proceed from this point, so you must go alone. Just continue straight along the path, and it shouldn’t be difficult to find.”

“Okay, I understand.”

Seeing that Lilith’s subordinate could not proceed indicated they had reached a place where Lilith’s base was located. It appeared they had already arrived at the Klifirot of Gamaliel.

Just when Nahun was about to walk twenty steps ahead after parting ways with the demon, he frowned at an unpleasant sensation.

“…Let go.”

Before he knew it, a delicate white hand was wrapped around Nahun’s waist. As he swiftly tried to shake it off, a thin, alluring voice gently flowed from behind.

“Oh my, aren’t you being too cold towards me?”

“I’ve never been in a situation where I would be called anything close to being connected with you.”

“Hehe, you’re still as very stubborn as ever.”

Releasing Nahun, she lightly chuckled and stepped in front of him. Despite a change in clothing, it was still an overly provocative outfit worn by the Great Demon.

“Lilith, I’m not here to make jokes.”

“Of course you’re not. You always visit for boring and serious reasons. So, why have you come to Hell this time? Oh my, are you finally tired of the pleasures of the Demon World?”

“It’s not that; I have a question about the Heavens.”

“The Heavens?”

Lilith seemed slightly taken aback by the unexpected question. However, after a brief moment of surprise, she regained her composure and smiled alluringly.

“Interesting, I never thought you’d ask me about the Heavens.”

“What’s so interesting about it?”

“Well, in matters of the Heavens… in truth, there’s no one who knows better than I do in this Hell. You might know more about the Heavens than Taumiel does, hmm, indeed, it seems the seals have tightened your constraints.”

“Have you heard any recent news?”

“Recently?… Ah.”

Lilith nodded slightly.

“That was your doing, wasn’t it? No wonder, Kamiel wouldn’t have backed off against demons otherwise.”

“…Aside from that talk, do you have any additional information? Perhaps from Taumiel?”

“Oh my, are you trying to extract information from me now?”

“Who’s ‘my dear’? As I said before, if you keep babbling nonsense, this conversation ends there.”

“You seem a bit more sensitive than before?”

Lilith chuckled. It was not in her nature to laugh so much. Yet, she found herself smiling at each of Nahun’s actions because he exhibited responses that would typically be uncharacteristic of him.

The old Nahun would not have batted an eye, regardless of how much Lilith teased or made lewd comments.

“The seals must have changed your personality quite a bit.”

“Then, do you know or not? Just tell me that.”

“You’re asking for information, yet you seem so insincere. If I told you something here, what benefit would I gain from it? I wouldn’t support you unless I have some clear benefit myself.”

Nahun narrowed his brows slightly. However, since Lilith was not wrong, he was left with no choice but to speak.

“What do you want?”

“I want to spend a night with you….”

“I refuse.”

“Oh?…No, you. I’m truly curious. How can you deny wanting to sleep with someone as perfect as me? How can you not feel a desire to sleep with such a flawless woman? Are you perhaps genuinely a virgin?”

Lilith was a beauty, objectively stunning and voluptuous, while still maintaining a youthful appearance, striking the perfect balance.

However, to Nahun, none of that mattered. He had already become involved with someone and had just poured out all his desires to that person not long ago.

He had truly reached a point where he could view other women as mere distractions. Nahun clicked his tongue and said.

“Go to your devoted one. Don’t start spinning your body around unnecessarily.”

“Oh my, are you worried about me right now?”

“…How does that even count as worrying?”

Nahun showed a reaction of not understanding, but Lilith spoke with an expression that showed she didn’t care at all.

“Alright, since you’re worried about me, I suppose I won’t be too resistant, right?”

“So I didn’t particularly worry….”

“One thing.”

“Hmm?”

“I’ll answer one thing. There are things I don’t know in detail, but this is something Taumiel told me not to talk about at all. But because it’s you, I can share at least this much.”

“What is it?”

Lilith gestured for Nahun to bow his head slightly. Nahun hesitated, suspicious of her actions, but he could not afford to abandon the inquiry.

“There are rumors that the divine authority of the Heavens has perished, and Metatron has succeeded it. It’s merely speculation, so I’m not sure of the accuracy…”

“…The divine authority of the Heavens has perished, and Metatron has inherited that power?”

This meant, according to Lilith’s words, that Metatron had inherited divine authority. Upon hearing this, Nahun remembered something that came to mind.

‘…Then is that the reason for Kamiel’s changed attitude?’

“It doesn’t seem complete, but given the current situation, it seems highly likely. Not long ago, even during the Great Celestial War when they intruded into Hell, there seemed to be an oddity in their forces, and even though they lost an outstanding general named Mikael, their response was lukewarm, which is strange. If they had such an opportunity, they should have engaged the entirety of their forces from the Heavens.”

Lilith’s explanation clearly resonated. Nahun thought slowly for a moment.

“Isn’t divine power something that even great demons cannot contend against?”

“They cannot contend. If it’s real power from a ‘God,’ not merely angelic strength.”

“Then action must be taken beforehand.”

“Taumiel will probably reach a conclusion soon.”

“…What conclusion?”

“Given that Mikael is dead and Kamiel has weakened, it appears they’re contemplating the best time to invade from our side. Additionally, they are considering deploying someone exceptionally strong to ensure that does not happen.”

Nahun spoke with slight unease.

“Someone strong?”

“Yeah, you’re talking about that person, right?”

Lilith simply explained to Nahun.

“A ‘kingdom’ invasion through Nehemot is one of the targets Taumiel is thinking about.”
