From now on, Mu Yanxin would be called Mu Yanxi.
Although it sounded like just a single character’s difference, the name indeed had a slightly feminine air to it.
Still, it barely remained within the range she could accept.
After returning home, Mu Yanxi went straight to her room and closed the door behind her.
She had many questions to ask the Immortal Brain, but there had been so much happening along the way that she hadn’t been able to calm down and think things through carefully.
Even so, under her mother’s urging, she took off the silver combat uniform she was wearing and changed into the newly bought home loungewear.
The loose and soft clothes were indeed extremely comfortable.
Mu Yanxi even began to doubt whether, if she returned to her original world, she would still be able to get used to those rough linen garments.
Even the large bed she was sitting on was far more comfortable than the cave residence she used for closed-door cultivation in her past life.
According to what the Immortal Brain showed her, the mattress was made of Jade Silkworm Silk and Heavenheart Cotton.
Although they were only the products of low-grade Demonic Beasts and spiritual plants, they were soft and smooth.
Lying on the bed could even make a person sink in, making her not want to get up—its allure was truly frightening.
This gave Mu Yanxi a strange sense of contrast.
Her cave residence in her previous life had been luxurious and spacious, yet it was cold and lonely, and not comfortable to live in at all.
One could only say it provided a place to cultivate.
But this home, her own room—even though it wasn’t very large and the decorations weren’t that fancy—it was filled with a sense of warmth and comfort that made her completely relax.
If given the choice, Mu Yanxi would say she liked this room better.
The civilization of this world was highly developed—this was the conclusion Mu Yanxi reached after going out to see the city, hospital, and marketplace.
This was absolutely not the result that could be achieved by a few or a dozen cultivators relying on their personal might.
In her previous world, all cultivators were nearly obsessed with bitter cultivation, not sparing a thought for life or entertainment.
As for technological advancement, no one cared about that at all.
Mortals were also suppressed by cultivators with unseen hands.
For tens of thousands, even hundreds of thousands of years, they maintained a life of farming and self-sufficiency.
Immortals maintained the emperors they supported, used spells to ensure favorable weather for the people, and would intervene to suppress rebellions when necessary.
So, for countless years, nothing had changed—and it seemed as though things would always remain that way.
Once, Mu Yanxin had thought this was only natural—that this was the law of the Heavenly Dao.
No one questioned this way of life, and no one tried to change it.
Or maybe some had tried, but they never caused even a ripple.
But today, Mu Yanxi saw the nooks and crannies of Yuzhen City.
She saw the depths of the hospitals and marketplaces, witnessed countless unbelievable technologies, and saw a world where everyone was a cultivator.
Yesterday, she had just regarded this as a difference between two worlds—though strange and dazzling, it was only another world.
Today, she truly understood—this was the result of Immortal Way technology flourishing.
Or perhaps, not the result, but the process itself.
Even the cultivation system seemed vastly different from her previous life.
Why had no one questioned this before in her past life?
Everyone cultivated along a fixed route, thinking it was the only path to immortality.
No matter how many changes there were in cultivation methods, the essence of the realms never changed.
Perhaps this was the broad road refined by countless ancestors through repeated tempering.
Some geniuses might wish to improve it, but relying on their own power, they could only make small tweaks and minor repairs—never true reform at the root.
Thus, Mu Yanxi’s first question was: “Immortal Brain, what exactly are Life Spring and the Infinite Dantian?”
