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

"Ordinary human immortals on land live for no more than a thousand years. This is not the will of Heaven, but a limitation that has existed since the beginning of the world."

Mu An frowned. He vaguely sensed something: the Heavenly Dao of this world was probably just a hazy will, far from being perfect.

A nascent Heavenly Dao cannot possibly constrain the entire world; logically speaking, there should be many loopholes to exploit.

"What does that mean?"

The spring breeze blew through the gaps in the mountains and onto the water, creating ripples that transformed the water mirror into three thousand fine threads.

"There are three thousand Great Daos. Heaven and earth were born from chaos and were nurtured by the Great Daos... Fellow Daoist, what do you think would happen to the world born from a higher-dimensional Great Dao if it were flawed?"

The Great Way?

Mu An narrowed his eyes. He naturally understood what the old master was saying.

He had already discovered the fact that there was no way to achieve immortality in the world through repeated experiments.

only……

The Great Way is flawed...

Why is it missing?

Mu An had a suspicion in his heart that he was unwilling to admit, and the possibility of this suspicion was not low.

"Isn't there any other way? But extending lifespan should be much simpler," Mu An asked again.

The old master gave him a meaningful look and gave a seemingly plausible but ultimately ambiguous answer.

"There are three longevity-promoting spiritual plants in the world: one in the Four Symbols Mountain, one in the Spirit Mountain Temple, and one in the Myriad Spirits Domain."

All three spiritual plants bloom once every hundred years and bear fruit once every hundred years, with each fruiting producing forty-nine fruits.

The same longevity fruit, when consumed for the first time, can extend lifespan by five years; the effect diminishes with each subsequent consumption. However, if one consumes three different fruits, although the effect will gradually decrease, the total lifespan can still be extended by ten years.

Seeing the joy on Mu An's face, the old master added another sentence.

"As far as I know, the longevity fruits of Lingshan Temple have been exhausted, and the next harvest will be in forty years... while the longevity fruits of Wanling Domain will be harvested in three years."

Mu An was not disappointed that Lingshan Temple did not have longevity fruit, but instead thanked the old celestial master directly.

"Thank you for informing me, senior. If I obtain the Longevity Fruit from the Myriad Spirits Domain, I will certainly donate three to the Celestial Master's Mansion."

"good."

The Celestial Master didn't ask Mu An if he was confident he could obtain the Longevity Fruit from the Myriad Spirits Domain, and Mu An didn't ask the Celestial Master if he knew what abilities the Cangyue Demon Saint, ranked fifth in the world, possessed.

Rankings are just for reference; take them with a grain of salt.

Only a fight will tell who is stronger and who is weaker.

Neither of them spoke again. Only the mountain breeze rippled across the water, and every now and then a large fish would leap out of the water, making a splashing sound.

"Senior, do you know if reincarnation exists in this world?"

This time, the old master did not give an answer, but stared at Mu An for a long time before asking a question.

"I do not know, but you, my fellow Daoist, should know the answer to this question better than I do... If you ever find the answer, I hope you can enlighten me then."

"If we can find the answer, I will certainly not hesitate to share it."

A gentle breeze begins to stir, and the small boat bobs on the water.

"Fellow Daoist Mu, I have one more piece of advice."

"Please speak, senior."

"On the great road, one should sever the ties of cause and effect and end worldly ties, for the world is full of heartless immortals."

……

Mu An stayed at the Celestial Master's Mansion for a month.

During this month, the old master had many conversations with him, which benefited Mu An greatly.

With the tacit approval of the Old Celestial Master, the world's largest library, the Boundless Library of Four Symbols Mountain, opened to Mu An, and the vast collection of books captivated him.

If given the opportunity to savor and read the classics in the Boundless Library, Mu An felt that his understanding of the universe would improve considerably.

Unfortunately, Mu An's time was very tight. He only stayed for a month, searched for some books about Tian Sheng Mountain, and left the Celestial Master's Mansion early.

Perhaps hoping to forge a good relationship and not wanting to be on the opposite side of Mu An in the future, the old Celestial Master was very polite to Mu An and even gave Mu An a jade tablet representing the Celestial Master's Mansion.

From now on, Mu An can also use this jade token to enter and exit the Boundless Book Pavilion.

This attitude made Mu An wonder if he was too ruthless to believe that the Celestial Master's plan was something that no living being could tolerate.

In a moment of reflection, Mu An rejected this viewpoint.

He was probably right; it's just that the Old Master's concept of good and evil differed from his own.

Mu An didn't want to think too much about the future. After returning to the Mu residence and spending a few days with the three of them, he went straight to Yongning County to see Lin Li, whom he hadn't seen for a long time.

Mu An planned to bring Lin Li along when going to Tian Sheng Mountain, since Lin Li was the person closest to Princess Yongning.

After not seeing each other for more than ten years, Mu An almost didn't know how to start the conversation when she saw Lin Li and the flower-arranging granny again.

The former senior is now very old, relying solely on his cultivation as a Celestial Martial Saint to maintain his body, with less than three months left to live.

Lin Li remained cold and aloof, but the flower-arranging grandmother was delighted.

Her life was nearing its end, and seeing her old friend was a truly joyful thing.

The elderly martial arts master pulled Mu An aside for drinks, recounting their past experiences and telling her own stories from her youth.

Lin Li tried to stop her from drinking at one point, but seeing how happy the flower-arranging grandma was, she gave up her plan to snatch the wine.

On the other side, seeing Lin Li and the flower-arranging grandma getting along like family, Mu An swallowed back the words she was about to say.

After chatting for a long time in a harmonious atmosphere, Mu An hesitated for a long time before finally asking the purpose of her visit.

"Miss Lin, I have something I'd like to ask you."

"Oh? Just say it."

"I'd like to know, when the princess was still alive, did she mention anything about the cycle of reincarnation and the underworld to you, Miss Lin?"

Before Mu An could finish speaking, the coldness on Lin Li's face vanished, replaced by red eyes and a hurried tone.

"What do you mean by that? Does it mean you've found the princess's reincarnation, Lord Mu?"

Mu An shook his head and pressed Lin Li, who was so excited she almost pounced on him, back down.

"That's not it, I just wanted to ask you, Miss Lin, about some things."

Suddenly pressed down, Lin Li calmed down from her excitement. She stared at Mu An for a while, took two deep breaths, and tried hard to recall.

After thinking for a while, Lin Li suddenly slammed her hand on the table and shouted at Mu An.

"It happened once! When the princess was little, she had a high fever and unconsciously murmured words like reincarnation and the underworld. At the time, I just thought the princess was scared because she was sick and didn't think much of it."

Lin Li's tone became increasingly agitated, her eyes never leaving Mu An's face for a moment.

"Lord Mu, you are incredibly powerful and your cultivation is unfathomable. Have you discovered anything related to the princess? I will do my utmost to help you in any way I can."

Mu An, whom she hadn't seen for over ten years, suddenly came to find her and asked about matters related to the princess. This made it hard for Lin Li not to speculate about various possibilities, and someone who had long given up hope suddenly felt a renewed sense of hope.

She clenched her fists, extremely excited, eager to hear what she wanted to hear from Mu An immediately.
