Mu Yanxin had never heard of something like life spring during the Qi Refining Stage in her previous life.
Not to mention the Qi Refining Stage—even when she reached the Nascent Soul Stage, there was never any mention of such a thing in her sect’s ancient texts.
Having a spring in one’s body that continuously gushed out spiritual energy meant that even if she was an ordinary person without any spiritual roots, she could still cultivate using the spiritual energy welling up from this life spring.
Right now, Mu Yanxin could feel the spiritual power flowing from her life spring slowly merging into her meridians, transforming into mana.
Although it was only a trickle, tiny as a thin stream, it was continuous and never-ending.
Mu Yanxin remembered something else.
Before the surgery, that female cultivator in the white dress had said that above life spring, there were higher grades: sacred spring, heavenly spring, divine spring, immortal spring, and others.
The spiritual energy flowing from her current life spring was still very little—if it were upgraded to a higher grade, wouldn’t even more spiritual energy come gushing out?
Previously, Mu Yanxin had thought that white-dressed female cultivator was just tricking her parents into wasting Spirit Stone on meaningless surgeries.
But after experiencing the effects of life spring herself, she only wanted to say: Sis, you were right. The sooner you awaken life spring, the sooner you can enjoy the benefits.
If one person awakened life spring while another didn’t, it would be like the former was constantly cultivating day and night, while the latter was stuck in place—the difference would only grow wider and wider.
Even if the spiritual power from life spring was minuscule, over time, the resulting gap would be enormous.
Mu Yanxin even somewhat regretted not following the white-dressed female cultivator’s advice to directly take a loan and open up the sacred spring.
Surely, the effects would be even better?
But this thought was dismissed from her mind within a second.
After all, it wasn’t her own spirit stone, and she couldn’t make her current parents bear any more burden, let alone borrow money.
She had to hold fast to her bottom line.
The effects of Jingmai expansion surgery and Tendon reinforcement surgery were that they could hold and absorb more spiritual energy.
They seemed to complement the life spring, but Mu Yanxin felt they were a bit useless.
She had no spiritual root, couldn’t sense or absorb spiritual energy from the atmosphere, and could only rely on that trickle from life spring, which wasn’t even enough to fill her previous meridians—let alone expanded ones.
With such a small flow of spiritual energy, there was no need to strengthen the tendons.
Perhaps it was useful for people with Heaven-level roots or above, but to her, it was meaningless.
As for the most confusing surgery, the infinite dantian operation—she really did feel like her dantian had become a bottomless pit that could never be filled, spiritual energy could be poured in endlessly.
According to female cultivator, this was a necessary procedure, but what was the point of it?
After confirming the surgery was a success, her parents happily signed the surgical paperwork and led Mu Yanxin out.
Halfway down the hall, Mu Yanxin deliberately lagged behind and whispered to the terminal ring, “What is the immortal brain?”
“Immortal brain is a type of auxiliary immortal chassis implanted into the human brain to replace the brain’s memory, thinking, and calculation functions. It’s also the highest grade of immortal chassis.”
“I previously told you about brain-computer interfaces; the Immortal Brain comes with its own interface,” the terminal ring replied.
Mu Yanxin sucked in a breath of cold air.
What on earth was an immortal chassis, and it could even be implanted in the brain?
Replacing memory and thought?
The brain is the most important part of the human body—how could anything just be casually implanted there?
The reason she couldn’t help but ask the terminal ring was that, during surgery, she was knocked out by anesthesia from female cultivator , and in the haze she felt something in her brain speaking, claiming to be the Lingxiao Palace 6000 Flagship Immortal Brain.
Even now, she could vaguely sense that thing inside her head.
“Xin’er, what’s wrong? Why are you lagging behind? Hurry and catch up, there are a lot of people here, don’t get lost.”
Her mother quickly noticed Mu Yanxin wasn’t following and called back.
“Okay, Mom.”
Mu Yanxin hurried to catch up.
She didn’t expect that when she reached her parents, her father casually asked, “Just now I think I heard you talking to the terminal ring—what were you asking about?”
Mu Yanxin’s heart thumped.
She’d been too hasty and shouldn’t have asked about the immortal brain with her parents still around.
Just as she was thinking of an excuse, the terminal ring honestly answered her father’s question: “Master was consulting me about the immortal brain.”
What the terminal ring actually meant was that Mu Yanxin had asked what the immortal brain was, but when it reached her father’s ears, he took it differently.
His expression changed, “You little rascal… uh, do you still want to get an immortal brain implant?”
Her mother’s expression changed as well and she shook her head, “It’s difficult, Immortal chassis surgery costs at least tens of thousands of spirit stone, and an Immortal Brain implant costs at least a million spirit stone. Our family can’t afford it.”
“No, that’s not what I meant.”
Mu Yanxin, seeing her parents misunderstood, quickly explained, “I don’t want to get an Immortal Brain implant, I was just curious about it.”
But in her parents’ eyes, being interested in the immortal brain meant wanting an implant.
If it had been the old Mu Yanxin saying such things, her father would have already started scolding.
But now that their son had become a daughter, and seeing Mu Yanxin’s somewhat unfamiliar yet refined face, her father found he couldn’t scold her at all, and could only say calmly, “We really can’t afford an immortal brain implant. Especially since the surgery just now used up a lot of our savings. You shouldn’t think about it anymore.”
“Xin’er, Mom knows you want to improve, but the immortal brain is really beyond our means right now. How about, once we save up some spirit stone, we first get you a brain-computer interface surgery, and then install a few immortal chips as substitutes.”
Her mother came up with a cheaper alternative.
“That’s not a bad idea. A cheaper brain-computer interface costs just a few tens of thousands of spirit stone, and a few cultivation method Immortal Chips are just a few thousand more.”
“It would make studying for the high sect entrance exams and entering the Taiqing Immortal Domain much easier—it’s definitely worth it,” her father said with a gentler expression.
Although she didn’t really understand what immortal chips were, Mu Yanxin still waved her hands, “No need, Mom, Dad, I was just casually asking. I don’t want any implant surgery, and I don’t need a brain-computer interface either.”
The hospital was still crowded as ever, and her father didn’t want to discuss it any further here.
He just nodded, “Alright, let’s get to the car first. We’ll discuss it more when we get home.”
The three of them continued walking toward the hospital exit.
Because of the talk about the immortal brain just now, the previously joyful atmosphere from the successful surgery had cooled off.
But Mu Yanxin was still thinking: the way her parents talked about the cost and burden of immortal brain implant surgery showed that the original owner of this body probably hadn’t received such an implant.
So, what was the thing in her head now?
How did it get there?
Was it really an Immortal Brain?
Thinking back, the only possible explanation was that it had something to do with the old man who kept appearing in her memories inside a cave.
With a feeling of unease, Mu Yanxin swept her divine sense across her own brain—a cultivator’s habit, always scanning unknown objects with divine sense first.
A dignified female voice sounded in her mind again:
