"I won't force you to come home with me this time! I'm going to use the back room to change clothes and then settle down la la la la."

Ai Qinglan hummed an unknown tune and went to the backyard to find a room, leaving only Chen Feng slumped on the living room couch and Wang Qi, who had no idea what to say.

Wang Qi felt he should break the awkwardness first, so he said, "Senior Sister Ai really... speaks whatever comes to her mind. I've never seen any girl hint at 'something' with one sentence and then pat her chest to show her girlish heart with the next."

Chen Feng forced a smile, "What Sister Lan says... in some sense, isn't wrong. Her physical body has benefited from the Creation and Transformation techniques, and her lifespan is far beyond what any ordinary Golden Core could compare to... no, maybe she's even comparable to a Primordial Spirit now. But her spirit, it's still within the range of a mortal, at most just a bit unique. She might not easily get hurt physically, but her spirit is still immature, vulnerable, and can crumble..."

Cultivators who have mastered the Life Flame often advance to Primordial Spirit within decades, and since Modern Cultivation was established only two thousand years ago, there aren't any cases of Primordial Spirit Cultivators depleting their lifespan, no evidence until now that the Life Flame can prolong life.

Wang Qi patted Chen Feng's shoulder, "Look on the bright side. With Senior Sister Ai like this, you have less to worry about. No need to fret over her getting knocks and scrapes or getting injured during training."

Chen Feng shook his head, "It seems I only realized today, she doesn't need protection at all."

Ai Qinglan didn't even need a self-protection mechanism, so how could she require protection from others?

Wang Qi's eyes darted, "Actually, isn't this a blessing in disguise? I mean, aren't we at a bottleneck now? If we bring Senior Sister Ai into this..."

Seeing that Ai Qinglan wasn't going to leave, Wang Qi set his sights on her.

Before Wang Qi could finish, Chen Feng grabbed him by the collar, "That's absolutely not possible."

Wang Qi raised his hands, "Then what's your plan? Spit it out. Can you drive your wife away?"

Chen Feng had no reply. He knew what kind of person Ai Qinglan was. If he told her the truth, she would definitely choose to stay with him.

Seeing Chen Feng silent, Wang Qi continued, "There you see, if you can't drive her away, we might as well take her in."

Chen Feng covered his forehead, "We can manage with just the three of us. We didn't attract any Outer Disciples of Divine Capital before, did we?"

"It's a matter of skill," Wang Qi said. "Divine Capital is a Dead Land for Modern Cultivators. The level of research on Modern Cultivation here isn't particularly high, with limited benefits to bringing them in, but a high risk of leakage. But Senior Sister Ai is different, she alone is worth one and a half of you, perhaps even both of us combined."

Seeing Chen Feng still unwilling to relent, Wang Qi added, "Look, since Senior Sister is staying, and I also didn't make any fuss about it..."

Chen Feng's anger grew, "You never consider the consequences of failure. To put it nicely, that's called confidence; to put it bluntly, that's called arrogance. You still haven't thought about the consequences of Heavenly Sword besieging the city! And Youjia took part in that reckless real-world test with you, she was involved from the start! But what about Sister Lan? She's different!"

"Even if she stays in Divine Capital, she's the one among us least likely to die, right?"

"Even someone of her level would die if they lost more than 70% of their mass in an instant!"

"Why are you two fighting at this time?" Chen Youjia, who was collecting data outside, had just returned. Seeing the scene, she forcefully separated Wang Qi and Chen Feng, "Both of you, grow up. This isn't the time for quarreling! Have you forgotten? We still have a task!"

Wang Qi quickly recapped the situation for Chen Youjia. Her first response was not like to stake a position on "whether to bring Ai Qinglan into this," but rather, she uttered "Oh" and looked at Chen Feng, "Be careful tonight."

Clearly, she was teasing him about the incident from seven or eight years ago when Chen Feng nearly got forcibly pushed.

Chen Feng wanted to say something, but Ai Qinglan had already changed her clothes and bounced next to Chen Feng, hugging him, "Xiao Feng!"

"Sister Lan, don't do this..." Chen Feng struggled a bit symbolically before allowing Ai Qinglan to hug him. At the same time, he transmitted his thoughts to Wang Qi and Chen Youjia using spiritual sense, "Don't tell her anything before I decide!"

"Sure, sure." Wang Qi reached for Chen Youjia's hand, "Perfect. Senior Sister, give me the data you've collected, I just got an idea, and I need to check it out. To the room."

"'To the room'?" Ai Qinglan let out an "oh oh" mischievous laugh, teasing, "Junior Brother, it's broad daylight, daylight!"

Wang Qi raised the hand linked with Chen Youjia's, "As you see it, we're in that kind of relationship. And right now, my room doesn't even have a place to lie down, it's very safe."

"Is that so." Ai Qinglan nodded her head but secretly transmitted to Wang Qi, "Then remember to apologize to Xiao Miao later."

Wang Qi stiffened for a moment. He hadn't expected Ai Qinglan to suddenly bring up that.

Ai Qinglan had already greeted Chen Youjia, "Senior Sister Chen Youjia? You still look so much like you did back then!"

"Uh..." Wang Qi felt Chen Youjia's grip on his hand suddenly tighten. Chen Youjia squeezed out a smile, "Senior Sister Ai has become much prettier than back in the day."

After the two girls exchanged pleasantries, Chen Youjia dragged Wang Qi away.

In Wang Qi's room, the two once again began calculations and simulations. After processing the data, Wang Qi asked Chen Youjia, "Junior Sister, what do you think about me inviting Senior Sister Ai to join this matter?"

"This is not for us to decide. Even if Chen Feng sorts out his emotions, having Senior Sister Ai join won't make it more efficient."

Wang Qi was surprised and touched Chen Youjia's head, "Tsk, tsk, Junior Sister, you actually have such insight on these matters."

Chen Youjia pouted discontentedly, "I am, after all, a girl."

"Sorry, sorry." Wang Qi laughed twice and sighed, "Speaking of which, Chen Feng has it tough too. While others speak of how a little separation piques the passion of a new marriage, he finally gets to see his fiancée and has to start with a fight."

Chen Youjia stared at Wang Qi, "That's men's view. If you ask me, Chen Feng deserves it. A fiancé that ran away for three years must be fought first upon meeting, and then we can talk about other things!"

Chen Youjia made this comment with great vehemence, especially stressing the word "ran". Wang Qi couldn't help but feel a bit guilty, "Why are you looking at me… heh heh heh…"

That evening, Wang Qi once again entered the Ten Thousand Immortals Illusion Realm to report the day's progress to Feng Luoyi.

Over the past few days, their main achievement was still the "Refining God to Subdue Demon Grand Technique". Only this was a mature solution that could be widely disseminated. As for the "Divine Spirit" operating system, Wang Qi dared not use it.

After examining the cultivation technique given by Wang Qi, Feng Luoyi closed her eyes and pondered for a moment before asking, "Is this your answer?"

Wang Qi shook his head, "A temporary measure, or what might be called an emergency response."

The ground in front of Feng Luoyi suddenly lit up. Amid a burst of white light, a three-dimensional grid array appeared in front of Wang Qi. Feng Luoyi spoke, "Each unit here represents a member of the Human Clan. First, each unit has two states: 'survival' and 'death'. Second, each unit has multiple attributes, ranging from Mortal to Carefree. From Mortal to Carefree, one can ascend but not descend; third, Mortals automatically die after sixty-five time units, while Qi Cultivation Cultivators..."

Wang Qi immediately understood. This was a prediction of the future of the Human Clan's survival and proliferation under the simultaneous existence of the Heart Demon Curse and the Refining God to Subdue Demon Grand Technique. Content sourced from MV4LEMPYR – My Virtual Library Empire.

Feng Luoyi took a glance at Wang Qi, "This model was invented by you. You understand it, right?"

Wang Qi nodded lightly.

With a light tap from Feng Luoyi's finger, the powerful computational capability of the Ten Thousand Immortals True Mirror began driving the operation of the model.

Green represented uncontaminated areas, while red indicated areas that had fallen to the Heart Demon Curse System. The stage of an individual's cultivation was indicated by varying shades of color, with healthy Mortals represented by light green and the Qi Cultivation stage by a slightly darker green, followed by grass green, emerald green, all the way to the "black" of the Carefree stage.

Cultivators above the Qi Cultivation stage might have the chance, through practicing the technique invented by Chen Feng, to refine the Heart Demon Curse's spell power and switch their status from red back to green. Mortals, however, were beyond help.

Furthermore, although the Refining God to Subdue Demon Grand Technique could create inheritable Divine Skills, Mortals couldn't use them. Even if they forced activation, the Mana-less Mortals would only consume their Primordial Qi and shorten their lifespan.

In front of Wang Qi, the red and green squares flickered rapidly. At first, red and green could hold a stalemate within a limited scope. But soon, red started to lose control, like a reckless beast, engulfing the green areas with an overwhelming momentum.

This was a Chaos model, and every calculation could yield different results. After some time, the grid array in front of Wang Qi split again. Swiftly, a vast multitude of Cellular Automata models filled the space between Feng Luoyi and Wang Qi.

As far as the eye could see, it was a sea of red. The predicted outcome of all Cellular Automata models was that the Heart Demon Curse had infected all Mortals, and the foundations of Immortal Dao had been lost.

Feng Luoyi was neither disappointed nor mocking Wang Qi. She calmly closed the simulation, "Unqualified."

Wang Qi sighed softly. Indeed, the Refining God to Subdue Demon Grand Technique could form a resistance among the entire population, but it required several generations to be effective. In contrast, the Heart Demon Curse spread exponentially faster and faster as it progressed. In just a few years, it could thoroughly infest all of Shenzhou.

After verifying Wang Qi's results, Feng Luoyi did not send him away but handed him several papers. Pointing to the first one, she said, "The reply from Thousand Mechanism Pavilion to your last question about how to build protocols between conventional calculator systems and probabilistic algorithm systems is here. Additionally, these papers are from the Genting Sect, focusing on the domain of logic. There are also a few papers from the younger generation of the Primordial Spirit Stage of Wanfa Sect, mainly about the construction of the Ten Thousand Immortals Illusion Realm and Path Rank writing."

At this point, she paused, then smiled, "Now, everyone who can participate, from Wanfa Sect's Thousand Mechanism Pavilion, Yangshen Pavilion, and Innate Peak, is prioritizing solving your problems."

As Wang Qi's research progressed, the support Feng Luoyi provided also increased. Wang Qi's questions were often referred to specialists in the field by him, or he would solve them himself. Moreover, he often sent papers to Wang Qi, some of which included confidential technologies listed by the Immortal Alliance. The content Feng Luoyi selected was all urgently needed by Wang Qi or could open his mind to new possibilities.

Wang Qi's ability to get the Anti-Heart Demon Spell to this stage in a month was also thanks to Feng Luoyi's guidance and the skewed resources of the entire Divine Capital's research.

Subsequently, the two exchanged on Mathematics for a while.

Finally, when Feng Luoyi let Wang Qi leave, Wang Qi ventured his own question, "Teacher, now I want to bring another person in to help me research the Anti-Heart Demon Curse." (To be continued.
