Start in Terra, immortal

"You brat! What are you doing? How dare you touch that book of prophecy? Looks like I'll have to kick you out!"

With a flick of his wrist, the boy knocked the large slingshot from Becky's hand to the side. Muttering to himself, he conjured a magic book out of thin air; its pages flashed with light, and constellation symbols began to illuminate.

"Wait!" Just as the boy was about to finish casting the spell, the adventurer arrived in front of Becky and stopped the boy's next move.

"Tch! I'll let you off the hook, out of respect for being an adventurer!"

The adventurer picked Becky up from the ground, and after seeing that she was alright, he continued to say to the boy, "You still haven't explained these books to us! Go on."

Seeing this, the boy stopped paying attention to Becky and continued to explain, "My master used magic to record his memories so that he could show them to one person. That person is you—the adventurer!"

You were guided here when they deemed you qualified to access these memories. Now that you're here, I'll grant you access to view these memories.

After speaking, the boy spread his arms in front of his chest, and seven magic books radiating a unique light appeared in the corridor.

"Wait a minute!" west Lan's loud voice suddenly rang out, "If we want to read these books, does that mean we have to learn these languages ​​too?"

Disdain returned to the boy's face: "Do you think we're fools? We were prepared for that."

With a "click," one of the seven books suddenly unfolded, gradually expanding into the shape of a door.

"Once granted viewing privileges, one can recreate the memories within these books. These books are essentially just passageways—passways leading to the memories of magicians. If one is prepared, one can enter at any time."

At this moment, Maisiell stopped Becky, who wanted to come in with him, and said, "Becky and I will stay outside to repair the navigation system on the Vahailt. You can go in."

Upon hearing this, the adventurer looked at Becky: "That's fine then. Becky, our safety on the road home depends on you!"

"Don't worry, this is a piece of cake!" As a special-type robot, Becky didn't think too much about it and readily agreed. In her mind, adventurers were trustworthy people.

"Before you go in, let me remind you one more time. These seven books are seven memories recorded by a mage during his travels around Arad. Each book corresponds to a different world."

"World? You mean a world like the heavens or the demon realm?" Alice asked.

The boy's face showed helplessness: "It seems I need to add something. The dimension where Planet Arad is located contains multiple worlds. Among them are those places you are familiar with."

The dimensional boundary where this library is located can also be considered a world. Explaining each of these worlds to you one by one would be too troublesome.

All you need to know is that the seventh book, which you enter first, is the last place the wizard visited before building this library—a world known as the "Never-Ending Hell of Sin."

"A never-ending hell of sin!?" Alice suddenly exclaimed, "I never imagined such a place actually existed!"

Seeing that the others were looking at her, Alice explained, "In the past, it was said in the Dark Elf Kingdom that the eternally restless Hell of Sin was a place where the disrespectful, neither alive nor dead, remained."

The necromancers of the Dark Elf Kingdom often make pacts with the undead there. I initially thought it was just a rumor about the necromancers' magical abilities, but I never expected…”

"Normally, only one adventurer was allowed to enter, but since you two have been through so much with him as companions, I made an exception and let you in!"

Soon, the three of them entered the world of Volume Seven—the eternally restless hell of sin—through the portal that opened from the book.

The moment they stepped inside, eternal darkness enveloped the three of them.

"In this dense darkness, a moment's carelessness could lead to being possessed by the spirits here." With that, Alice plucked a string from her harp, and a magic circle appeared beneath the three of them. "I will protect us with magic; proceed with caution!"

Along the way, the three of them moved slowly, occasionally encountering some mindless dark monsters, but none of them posed any real threat to them.

Until—they met a man who claimed to be the prince of the Spider Kingdom.

"My name is Nicholas, and I am the prince of the Spider Kingdom."

"He seems different from the undead we've encountered before; he seems to have consciousness," the adventurer said, somewhat surprised. This Nicholas before them was completely indistinguishable from a living person.

"Depending on the amount of resentment and power of the spirits here, some of them possess sentience," Nicholas explained.

"So, you're a ghost or a god?" west Lan asked.

"No, no, no, ghosts and spirits are people who have lost their bodies and only have their souls left. But someone like me, strictly speaking, cannot find peace and cannot die."

I was supposed to go to the underworld, but Charon stopped me from going there on the grounds of disrespect. So I belong neither to the underworld nor to the mortal world, and can only wander in this eternally restless hell of sin.

He paused, then continued, "I now follow the will of Moros, the ruler here, and wait for the opportunity to retaliate and turn me into this person."

"Speaking of which, you must be an adventurer to be able to tolerate this sinful atmosphere, right? Welcome, adventurer. Lord Moros, the Primordial Fear, has been waiting for you for a long time."

Upon hearing this, Xilan was somewhat confused: "Isn't this from my memories? Why would people from my memories know about adventurers?"

Alice shook her head, indicating she didn't know either: "It seems there are memories in the book that haven't been frozen in time..."

While the two were pondering, Nicholas had already engaged the adventurer in a fierce battle, seemingly testing the adventurer's strength.

The sparring match between the two quickly ended with Nicholas taking the initiative to lose.

"It seems you are indeed an adventurer." Nicholas took a page from his pocket. "This is the old man's memory page. Go inside, and you'll see him..."

After leaving behind the pages of memory, Nicholas vanished into the darkness. Only the glowing pages remained, shining brightly in the darkness of hell.

The adventurer sheathed his weapon and reached out to pick up the pages to study them. Unexpectedly, the moment he touched them, the three of them were pulled into the memories within the pages.

The first thing you see is a giant tree, entrenched in darkness and surrounded by glowing flowing water.

Beneath the tree, an elderly magician was kneeling on one knee, gripping his staff tightly with both hands, struggling to stand up.

"The darkness here is so intense that even light cannot withstand it. Without rifts connecting different dimensions, dimensional travel would be extremely difficult."

After slowly standing up, the elderly magician sighed, "It seems that this place is indeed no match for the underworld, where ghosts and gods gather, let alone the spirit world."

The boundary between life and death is forbidden, and it's almost impossible for anyone to interfere here. It's truly a more suitable place than the spirit world…
