Immortality: Starting with a grave, I'm invincible when burying corpses.

Across the desk, Mu An paid no attention to Xuan Yuan Wu Mu's shock, nor did she care what Xuan Yuan Wu Mu was thinking.

He came to this world only to find a way to prolong his life; otherwise, Mu An cared about nothing else.

Once the boy had calmed down a bit, he continued to ask.

"Since you are a member of the Taiyuan Empire's royal family, you must know many secrets. How much do you know about the true demons and great demons in the Demon Abyss?"

The voice in his ear remained as calm as water, but it was precisely these calm words that made Xuan Yuan Wu Mu tense up completely.

After much deliberation, he cautiously asked, "Where would you like to begin, senior?"

"Lifespan, how long do the Great Demons and True Demons in the Demon Abyss live? And are there any life-extending items in the Spirit Realm?"

Upon suddenly hearing the words "lifespan," Xuan Yuan Wu Mu abruptly raised his head to look at Mu An, but before he could examine him closely, realizing something was amiss, Xuan Yuan Wu Mu shifted his gaze back to the table.

Could it be that this senior's lifespan is coming to an end?

Such a thought flashed through Xuan Yuan Wu Mu's mind. It doesn't seem quite right, does it?

No, how could a junior like him, who is only at the Qi Refining and Spirit Transformation stage, possibly presume to understand such a senior?

Why would this senior ask such a question? Is he testing me?

No, no! Don't let your mind wander at a time like this, focus on answering the question!

After giving himself a warning, Xuan Yuan Wu Mu stopped thinking about it and carefully recalled the information he knew.

"So that senior may know, I do indeed know a little about things that can prolong life."

"Tell me about it." Even in an unfamiliar world, Mu An's words remained direct, without the slightest hint of tact.

He, the great philanthropist, really didn't know how to write the word "euphemism".

In the Nine Realms, if Mu An wanted something, others would always rush to deliver it to his residence; there was never any politeness involved.

With just a word from him, no matter where the treasure is or which race it belongs to, it must appear before him within half a month.

This is already considered very polite.

"For example, the most famous Taiyuan Fruit in Taiyuan City is grown deep within the imperial palace. Consuming it can extend one's life by five years, making it the most precious longevity treasure in the world; the Haiyuan Tea of ​​the Dinghai Sect can extend one's life by three years upon first consumption; the Cloud Mist Divine Flower of the Yunling Mountains can be used as a medicinal ingredient to make elixirs, which can extend one's life by three years upon consumption..."

The Crimson Flame Peach Tree of the Ten Thousand Flame Sect takes a hundred years to sprout, a hundred years to bloom, and a hundred years to bear fruit. It only produces two peaches every three hundred years. Consuming a peach can extend one's life by ten years, making it the most effective among all longevity treasures. Unfortunately, the production of the Crimson Flame Peach is too low, and it has never been circulated outside the sect…”

Seeing that Mu An's gaze was becoming increasingly strange, he tapped the table repeatedly with his free hand, making a series of crisp sounds.

Xuan Yuan Wu Mu was startled, thinking that the content he had said was too basic, things that ordinary people could know, which made this senior think that he was fooling him, and that was why he was dissatisfied.

Without bothering to continue introducing those life-extending items with little effect, Xuan Yuan Wu Mu quickly changed the subject and talked about what he thought was the most important thing.

"As for the Great Demons and True Demons you mentioned, senior, if I may be so bold, the Demon Race is fundamentally different from our human race. They are more like the spirit beasts of heaven and earth, born with a longer lifespan. If we must make a comparison, I'm afraid it's..."

Before Xuan Yuan Wu Mu could finish speaking, Mu An frowned and pulled a book out of the bookshelf.

The book pages turned automatically without any wind, flipping to the introduction of the Ice Phoenix Clan.

"The Ice Phoenix, blessed by Heaven and Earth, is a divine beast born in the coldest of lands. According to the book, an Ice Phoenix in the Immortal Realm lives for three thousand years, one in the Spirit Immortal Realm for five thousand, and even a True Immortal only lives for eight thousand. But as far as I know, the True Demons in the Demon Abyss can easily live for tens of thousands of years. What is the reason for this?"

It wasn't a senior member of the Ice Phoenix Clan after all?

After listening to Mu An's words, Xuan Yuan Wu Mu immediately had this thought in his mind.

But aren't the cloud whales of the Sea Ridge Clan the ones who despise humans the most? How could they transform into human form?

Growing increasingly confused, Xuan Yuan Wu Mu tried his best to suppress the growing curiosity in his heart and explained in the most objective way possible.

"Senior, as far as I know, no matter what kind of spirit beast it is, its lifespan is limited to eight thousand years. Even if it can extend its lifespan by various means, it is impossible to break through ten thousand years."

As for your statement that the true demons in the Demon Abyss possess lifespans exceeding ten thousand years, this junior is also unaware of this, as there is no such record in any of the ancient texts I have read.

However, I have two bold guesses, and I wonder if you would be willing to listen to them?

"explain."

"Our Spirit Blossom Realm has been at war with the Endless Abyss for five thousand years. In this long period of time, countless demons have died in the Spirit Blossom Realm, and we have come to know them to some extent."

According to the records of the Taiyuan Empire, most of the demons in the Demon Abyss have real names. Their method of inheritance is different from that of other races. They do not reproduce through normal means, but rather rely on their real names to inherit their lineage.

If real names were used as identifiers, it wouldn't be surprising if these demons could live for tens of thousands of years.

Mu An made a judgment in his mind immediately.

"True name? No, what was sealed in the Nine Realms was merely a great demon, yet it was able to live for eight thousand years within the seal. This is definitely not simply due to the inheritance of a true name. Rather, this Demon Abyss Will is truly very strange, unlike the normal Heavenly Dao, nor like ordinary living beings. Could it be..."

With some ideas in mind, and looking at Xuan Yuan Wu Mu across from her who seemed both expectant and nervous, Mu An spoke up again.

Tell me your second guess.

Xuanyuan Wumu nodded in agreement and continued.

"As for this second guess, it is merely a junior's conjecture, and I am not sure how accurate it is."

"It's alright." Mu An tapped the table, then with a flick of his sleeve, two cups of spiritual tea appeared before them. "Take your time."

Xuanyuan Wumu didn't stand on ceremony and picked up his teacup to take a sip.

A flicker of surprise crossed his eyes the moment the tea touched his throat.

"This feeling of spiritual energy..."

His confusion deepened, but Xuan Yuan Wu Mu continued speaking.

"As the senior said, even the lifespan of a spirit beast of heaven and earth is limited and cannot exceed the upper limit of eight thousand years. For a great supernatural being in the True Immortal Realm, it is far too few."

This junior believes that such a powerful being would not simply sit idly by and let himself pass away, but would instead try every means to prolong his lifespan.

"good."

Seeing that Mu An agreed with his point of view, Xuan Yuan Wu Mu showed a hint of joy on his face and continued.

"Thinking about the Demon Abyss's practice of keeping all living beings in captivity, I have a bold idea."

As he said this, Xuan Yuan Wu Mu paused for a moment. In front of Mu An, he looked up at the sky, as if worried that their conversation might disturb some unknown entity.

"Don't worry about it, just speak."

"The reason why the Endless Abyss keeps waging wars is to obtain a large amount of blood food. The higher the quality of the blood food, the more lifespan those demons can have extended... If I'm not mistaken, those powerful demons must have mastered a method to refine living beings and thus extend their lifespan."
