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

"Three years?"

The specific time requirement startled Mu Ling'er, and she couldn't help but mutter to herself.

Although Mu An hasn't mentioned anything about lifespan to her in recent years, if her intuition is correct, she probably only has five years left to live.

The life-extending items brought from the Spirit Blossom Realm did have some effect, but perhaps because Mu Ling'er had already consumed too many similar things, the natural treasures of the Spirit Blossom Realm did not have the desired effect, only extending her lifespan by a few years.

At this time, Mu An suddenly asked her to take care of such a child of mysterious origin, which inevitably made Mu Ling'er think a little more.

The name "Yongning" further fueled Mu Ling'er's doubts.

Upon hearing the name "Yongning," Mu Ling'er immediately felt that the name sounded familiar.

Memories surfaced in her mind, and Mu Ling'er quickly recalled a name she had heard when she was very young, a name that would occasionally be mentioned later.

Princess Yongning.

The first member of the Daqi royal family to invest in Mu'an, a rather legendary figure.

Strictly speaking, Mu Ling'er did not know anything about Princess Yongning, nor had she ever met her.

Princess Yongning passed away when Mu Ling'er was still young.

However, as an angel investor in Qishan Road, Princess Yongning's name was still somewhat familiar to Mu Ling'er.

If she remembers correctly, Princess Yongning's name should be Jun Yunxin.

And now...

Looking at the baby girl named "Yongning", Mu Ling'er's gaze became more complicated.

What kind of relationship does this child have with Princess Yongning from back then, and what kind of connection will she have with Mu Ling'er?

Mu Ling'er didn't think Mu An would do anything meaningless, nor did she think Mu An would harm her.

However, with Mu An not intending to tell her the details, the limited information and narrow perspective prevented Mu Ling'er from learning more, and she could only rely on guessing to deduce the situation.

After much hesitation, Mu Ling'er finally agreed.

"I'll take good care of this child, but... she punched right through my Five Elements Mystic Robe, and I feel like I can't withstand more than a few of her blows... Let me make this clear, I'm not afraid of such a small baby, nor am I afraid of pain, I'm just a little bit worried..."

The words, tinged with a hint of awkwardness and hesitation, startled Mu An for a moment before she burst out laughing.

He smoothed Mu Ling'er's hair, which had been ruffled by the river wind, and comforted her with a smile.

"Don't worry about that. The child's power will soon disappear. She may get sick often in the future, so you'll have to be patient."

"Sick? Can't it be cured?"

"Yes, it's very troublesome. Currently, only the World Origin can make her feel more comfortable. Although I have a world that is being nurtured, it also consumes a lot of the World Origin, so I can't give her much of it."

These words made Mu Ling'er frown and look at Mu An with concern.

"Using the very essence of the world to cure diseases? Wouldn't that affect the evolution of the Four Symbols World? Such a huge consumption, wouldn't it be too much of a burden for you...?"

As she spoke, Mu Ling'er walked towards the riverbank, muttering to herself.

"Such a troublesome person, let's just throw her back into the river. Isn't the old celestial master of Four Elephant Mountain quite free? Let's send him a message and have him take the child back. We don't want to get involved in this trouble. You're not in a good state right now, we can't let her affect you."

Although she said that, Mu Ling'er didn't really intend to do it. She didn't want Mu An to get into such trouble, but she wouldn't really bother with such a small baby.

He was pretending to walk towards the riverbank just so he could hear more secrets from Mu An.

Unexpectedly, this action made Mu An frown and give her a hard tap on the head.

"Nonsense! Be careful you don't get struck by lightning one day."

As soon as he finished speaking, as if his words had come true, a muffled sound rang out in the sky.

High above, a purple bolt of lightning traversed the sky, striking down from the illusory space where reality and illusion overlapped.

The lightning dragon rushing down from the sky left Mu Ling'er completely bewildered; she didn't even realize that the lightning was aimed at her.

Fortunately, Mu An was right beside her. Just as the lightning struck, a five-colored beam of light shot into the sky and collided with the purple lightning.

The falling lightning dragon also made Mu An's face turn ugly. He was just joking with Mu Ling'er, but he didn't expect that the broken mountain spirit would actually dare to strike people with lightning!

The mountain spirit of Holy Mountain is truly inconsiderate! How dare it attack Mu Ling'er! Does it think he doesn't exist?

With a cold snort tinged with anger, the phantom of the Book of Creation appeared behind Mu An, and a silver-white beam of light traversed space, sweeping towards a mountain range that existed between reality and illusion.

The beam of light shot out from the void and rushed straight into the underworld, which lies between reality and illusion, striking the rushing river above it.

The reaction was felt in the outside world, with a massive avalanche forming instantly around Tiansheng Mountain.

The towering Tian Sheng Mountain trembled again and again, and within the illusory Netherworld, several new scars appeared on the already cracked, pitch-black earth.

"You insolent mountain spirit! How dare you, a mere remnant soul, attack me! This time, I'm grateful for your loyalty in protecting your master, but if there's a next time, I will surely destroy your entire mountain body!"

The illusory holy mountain trembled and shuddered, before falling silent again after a hundred or so breaths.

The fleeting phantom of the Book of Creation also disappeared behind Mu An.

Conflicts in higher dimensions are difficult for ordinary cultivators to observe. Even though Mu Ling'er was right next to Mu An, she didn't know what was happening.

All she knew was that her heart skipped a beat, a wave of fear washed over her, and then she saw a bolt of lightning strike down from the sky. Mu An, who was clearly angry, pulled her behind him and used the Five Luminous Divine Radiance to disperse the lightning in the sky.

She had no idea what happened afterward, but even just what she saw was enough to leave Mu Ling'er speechless with astonishment.

"Wait...this...that lightning just now..."

Everything happened in the blink of an eye, but the moment Mu Ling'er was locked onto by the Purple Heaven Divine Lightning, she still broke out in a cold sweat.

Seeing Mu Ling'er still shaken, Mu An gently patted her head and comforted her softly.

"Don't be afraid, it's just a remnant soul that's a bit immature. I've already disciplined it. As long as you're not too harsh on this child, everything will be fine."

Seeing that Mu Ling'er still had doubts, Mu An continued.

"She is connected to my plans for the future and will play a very important role in the next few hundred years. But don't worry too much, you only need to take care of her for three years, and I will help you with any problems."

"Isn't there a student named Yun Wan at Sui'an Academy? You could have her come with you and help take care of Xiao Yongning. That would be of some use."
