I'm in the Teyvat running group

It would take them three days to understand this paper.

This allowed Shatang to have a rare few days of rest and spend a complete family reunion day at home with her children and other sisters. This is a day that happens once a month. Generally, it is chosen around the same time as the birthday of a child or a wife. Yunxiu's wife does not have a birthday in May, but Liuying's child, Yunpinghai, is born on May 23, so the family reunion day in May is this day.

Fireflies also rushed back from the lunar base.

The whole family gathered together, chatting about recent events and the progress of their various projects. Most of them were doing what they enjoyed, though some had changed. For example, Ayaka Kamisato, who had been managing the company's administration, had gradually started to delegate more of her work to her brother in recent years, while she herself stayed in Liyue year-round. After all, she had become Gan Yu's apprentice ten years ago and was now a powerful figure who had just entered the Legendary realm.

For Ayaka Kamisato, the growth of power might be more attractive than power right now, which isn't a big problem. In the world of Teyvat, if you're stronger than the Thunder General, then you can also become the Thunder God.

The biggest change in the Seven Gods over the past decade was that Fryna officially retired, and Mavica stepped down as the God of Fire. The current God of Fire is Kinich. After retiring, Fryna continued to be a big star. The Grand Governor of Fontaine was replaced. After Kares, a scholar from the Fontaine Academy of Sciences took over as the new Grand Governor. Navia continued to do her job as the Rose of the Thorns.

After retiring, Mawika's most frequent place is Mond, where she also formed a band. Most of the time, they perform for free as a hobby, but their level of skill is quite good.

Nata didn't have a retirement pension plan, but since Mavica was the retired God of Fire, Yunxiu was unlikely to neglect her. So, he arranged for her to be an advisor to the elite squad of the Chamber of Commerce, and to fight with Serene from time to time. Surprisingly, Mavica taught quite seriously.

The happiest person was, of course, the young master. What could be better than fighting against such a powerful opponent every day...

On the Liyue side, perhaps besides the retirement of Tian Shu and Tian Ji, the biggest change is that Tian Xuan suddenly broke through to the Legendary level one day, and now has a jade pendant around his neck. The powerful life force keeps Tian Xuan in good physical condition.

No one really bothered to figure out who was behind all this. After all, Tianxuan had originally planned to retire as well, but Liyue couldn't find anyone else to replace her. Qixing had also tried to get someone else to take over, so they set up a test. Anyone who scored over 70 points could work under Tianxuan.

The highest score for this paper at Yujingtai was 22 points.

In the end, Tianxuan had no choice but to work for a few more years. But after all, a person's lifespan is limited. So one morning, she woke up and told the person sleeping next to her about it. This person then used some methods to further improve Tianxuan's physical condition.

With the passage of time, working a few more years shouldn't be a big deal.

It can only be said that even with the Spirit Realm and various auxiliary methods, an excellent Seven Star is still indispensable...

After slacking off at home for four consecutive days, Yunxiu finally got the news from Sugar. She followed Sugar and Yunpingsi to Ochikanata. From there, they could take the space elevator to quickly reach the original Sky Serpent Ship at the top, which was also the space station. Yunxiu renamed it Lingxiao Palace, since it was a name that suited the tastes of the people of Liyue.

Starting from Lingxiao Palace, you can quickly reach the moon.

The restored Ochikanata is completely different from before. Teyvat is actually a planet slightly larger than Earth. According to Zhiqiong's mapping data, its radius is 7645 kilometers, and its gravity is also slightly lower than Earth's. Here at Ochikanata, it is about 0.95 times lower. The length of a day is also slightly longer, at 24 hours and 4 minutes. Therefore, the height of the space elevator reaches 3.93 kilometers.

Moreover, the launch method is completely different from the traditional space elevator. There is actually no "cable" here, but a "force field rope" composed of a space anchoring array, a lightning element constraint array and a lunar distance force.

This directly resulted in the launch mode actually being three-stage.

At the bottom is the lunar distance force ejection, which of course varies in ejection power. Currently, the space elevator is not open to ordinary people for travel, so most of the time it is a high-power ejection with an acceleration of about 4G. This intensity is sufficient for ejecting cargo and most spellcasters who are currently heading to the lunar base.

The middle section begins to use phlogiston technology for traction, released from the Lingxiao Palace at the top, to "pull" the space elevator car up. After reaching the Lingxiao Palace, it is propelled by a lightning element array to fly towards the moon.

The launch speed is fast, and the phlogiston technology makes the launch relatively smooth. However, it mainly depends on the initial velocity of the launch. Generally speaking, barring any unforeseen circumstances, it usually takes about 30 minutes to reach Lingxiao Palace. Then, you can take a connecting spaceship and reach the lunar base within an hour.

Yunxiu was naturally unconcerned. Although Yun Pingsi was only eight years old this year, his strength had already reached the level of the fifth ring, which was more than enough to withstand this acceleration.

Therefore, the three of them arrived at the lunar base in just over an hour by taking this space elevator.

Speaking of the architecture of the lunar base itself, the style is not actually that strange. It is not much different from some ancient buildings in Liyue Sumeru and Nata. The main reason is that the projection capability of the space elevator is quite good. With the application of protective magic array, there is actually no need to worry too much about causing any impact. However, it is precisely because anything is acceptable that it was ultimately built to resemble those countries, since those countries have the most technical personnel.

This place is about 10 kilometers long and 5 kilometers wide. It is a city that looks roughly rectangular. It is surrounded by a twelve-ring protective array set up by Yunxiu himself. Inside is a life cycle array set up by the Little Auspicious Grass King. Except that the gravity is only one-sixth of that in Teyvat, it is not much different from the ground.

This place is home to approximately 150,000 people, mostly mages and alchemists, many of whom are high-level experts. Of the twenty-three legendary peak mages in the academy, eight reside here permanently, and two legendary alchemists are also frequently stationed here. In terms of sheer academic concentration, it is undoubtedly the number one in Teyvat.

The downside, of course, is that most people completely ignored Yunxiu's existence and started enthusiastically discussing all sorts of issues with Sugar and Yunpingsi...

After chatting enthusiastically for over an hour, it was finally the legendary mechanic, Aino, who was already twenty-five years old, who stepped forward to invite Yunxiu to come and see their experiment.

"So, this is what Sugar is working on?" Yunxiu looked at the huge but still much smaller than the Demon God's energy core and asked, "Is Pingsi's theoretical model useful? Didn't he only solve part of the problem? It seems to have specific conditions?"

“Having specific conditions means we can make presets, and with presets, we can naturally implement them! You’re really not very smart in this regard!” Ai Nuo casually picked up a crystal plate and handed it to him, pointing to the data on it and saying, “Here, we tested it yesterday. Under low power operation, running at 20% power, it reached the level before the upgrade of the Shadow Furnace Core. Today is the full power test. If there are no problems, it can be applied to the Jade Pavilion and the War Fortress soon, and it can even be used to build space battleships!”

Yunxiu nodded. One of the main reasons why the upgrade of Qunyu Pavilion has stalled is energy. Originally, it was powered by high-purity energy crystals, but it is impossible to carry too much. Even with storage bags, it cannot burn them all instantly. Relying on the charging array will lead to insufficient charging speed. The power upgrade of Qunyu Pavilion has actually been stagnant for about three years. These three years have mainly been spent optimizing monitoring and tracking.

Although it was said after the war that no more ships would be built, after weighing the options, four more were eventually built, bringing the total to eight ships in the Qunyu Pavilion fleet. The original ships were also upgraded.

On the one hand, this thing is not expensive relative to its effect. The construction cost in the later stage can be reduced to about 1000 billion Mora. This is after a lot of upgrades. On the other hand, the effect is excellent. It has freed up a lot of the combat power of the Dead Zone. Now the troops in the Dead Zone are basically less than one-third of what they used to be, but the attack efficiency has increased several times.

The benefit of this is that the dead zone is gradually shrinking.

In ten years, the Dead Zone has shrunk by a full third. Part of the terrain of the Thousand Ravines Sandy Land and the Sweet Dew Flower Sea, which were originally polluted, has been revealed. Even though it is not something that can be resolved in a short time after being polluted by the abyss for hundreds of years, there is finally hope.

Secondly, the defense zones of the Northern Territory and He Guan in Zhi Dong also require the deployment of the Qunyu Pavilion. Many of Zhi Dong's original strongmen have left. Although the development in the last ten years has brought many people back and created a new batch of strongmen in Zhi Dong, it is still a bit wishful thinking to expect a short-term recovery. In recent years, although the pressure on the False Heaven has decreased, the pressure on the Dead Domain, the Northern Territory, and He Guan has increased.

However, with the support of the War Fortress and the Jade Pavilion, the pressure on the defense zone is actually relieved.

If this energy project is successful and allows humanity to obtain a stable and powerful energy core, then the Jade Pavilion can be further upgraded. It might even be able to be transformed into a space battleship. After all, as long as there is enough energy, it is theoretically possible to fly out of the atmosphere using the repulsive force array. The Jade Pavilion only needs to shut down the space array in advance, and after leaving the atmosphere, it can be modified and reinstalled on the moon.

"Start deployment, full-power test." Sugar, standing on the command platform, glanced at Ping Si beside him and nodded.

Yun Pingsi calculated the last few data points on his terminal and sent the calibrated data to all the technicians present. After inputting the data, the first full-power test was finally about to begin.

"One group, release the Langqi..."

"Group Two, continue supplying ignition energy, it's Ms. Sugar's Energy Liquid No. 4!"

"Group 3, continuously monitor the energy outlet and read the output data!"

Seeing that several sets were ready, Sugar quickly pressed the start button.

A standard-sized dragonfly, its stem, is a type of dragonfly. The text describes the process of shaping a dragonfly, its shape, and the characteristics of its shape. It mentions the characteristics of a dragonfly, its shape, and the characteristics of its shape. The text also mentions the characteristics of a dragonfly, its shape, and the characteristics of its shape.

Under the constraint of the magic array, the two liquids reacted violently with the peculiar plasma that had already been ignited and reached a sufficiently high temperature. Powerful energy was instantly released from the surrounding magic array and directly transmitted to the energy outlet, where it burst into a huge burst of light and was launched straight out of the base!

"Not good!" Yunxiu immediately cast a bunch of shields on herself, directly blocking the huge energy. Once the protective array here is broken, the problem will not be as simple as just a few people dying!

The power of this energy was indeed beyond everyone's imagination. Even the arcane defense on Yunxiu's body was shattered by the continuous impact. More than 200 layers were broken in just a few dozen seconds. The original 168 layers were almost completely blown up instantly, forcing him to continuously refresh the shield. He refreshed it for nearly 100 layers before the huge energy of the first wave was completely reduced.

"Without any magic array guiding it... it wiped out a full seven billion of my shield power? What kind of heaven-defying energy source is this?" Yunxiu exclaimed as she landed in front of this strange product, looking at the thing that had stopped reacting and asking in surprise, "What are these energy liquid and catalyst?"

"The energy fluid was extracted from the soil of the moon..." Sugar buried her head shyly in Yunxiu's arms. "I got it from the moon's soil... I've been searching for it for ages, and I've never had it before. It's so precious, so incredibly precious!"

"I'm fine, so this is what you made..." Yunxiu suddenly realized. Although he wasn't an alchemist, he knew what Sugar had made.

This is a peak that humanity in the original world might not have been able to reach in two hundred years—pure helium-3 fusion!

The substance extracted from sugar is helium-3 in this world...

"No wonder...then perhaps we really can create a true Steel Demon God." Yunxiu looked at the peculiar creation before her, picked up Sugar, and kissed her twice: "This is truly a super big surprise!"

"There are so many people...and my son is there too!"

Chapter 467 A Ten-Year Journey of Mother and Son's Legacy

“What does it matter if my son is here? He’s not an outsider…” Yunxiu picked up Shatang, teasing her while looking at the huge device in front of her. However, this hugeness was mainly relative to a person. In reality, it was much smaller than the Yuying Furnace Core and about the same size as the energy core of the Qunyu Pavilion. However, the core of the Qunyu Pavilion was mainly high-purity energy crystals. Although the storage bag provided some protection, it didn’t have much to worry about in terms of energy storage, but the output was not large enough.

Even though Xiaoyue used spatial magic to compress the area of ​​the energy chamber, the upper limit of output remained within the range of the familiar level. It was only by using the charging array to amplify it and stacking it multiple times that it could reach the level of killing god-level monsters.

“Yunxiu…Mr. Yunxiu!” Sugar shyly covered her head. “Put me down quickly, there are still many things to do.”

"Alright, alright..." Yunxiu put the alchemist down with great affection, even though she was already a mother, she still often acted this way. Then she looked at Yun Pingsi, who was rapidly looking at various data, and said with a smile, "Pingsi, how did you manage to find a stable solution to this equation? With just this one paper, you should be able to become a Sage in the Academy."

“That’s right. If Pingsi is willing to study at the Order Academy, our Number Theory School will definitely be willing to hand over the position of Sage to him.” The current Sage of the Number Theory School, Huma Yi Dina Zede, came up to Pingsi with a smile and said, “However, Pingsi is actually already very capable. His paper published two years ago was very insightful.”

"Um... what paper?" Yunxiu suddenly asked curiously, Pingsi hadn't mentioned this at home.

“It’s normal that you haven’t heard of it, because it actually solves a small branch of the problem. Although it’s very important, it’s not surprising that scholars in other fields are unaware of it.” Chu Li, the current head of the Department of Conjuration and a legendary high-level mage, handed Yun Xiu a crystal plate and pointed to the paper, smiling, “It’s this one, ‘The Application Prospect of the Moon-Alice Gauge Field in Three-Dimensional Resistive Magnetohydrodynamic Equations.’ This paper solves the problem of generalizing the gauge fixation method in the ring constraint problem. When my master was reviewing the manuscript, he even asked me if Ping Si had studied under anyone else.”

Yunxiu took the crystal plate, glanced at it briefly, and quickly understood what the paper was about.

Although he was somewhat confused about Ping Si's current research, he was quite familiar with the Moon-Iris Gauge Field. It mainly explained how the Light Realm Force and the Void Realm Force were transformed into the Seven Elements, and how the Seven Elements Force formed space. He was also studying related spells and papers, because from a defensive perspective, using the space layer itself for protection necessarily required understanding the conversion relationship between space and elemental forces.

Alice's main contribution here is solving part of the problem of how to anchor the wish spell to the spatial array, that is, using runes to construct the stability and continuity of the space itself.

“Pingsi even consulted me about electromagnetism…” Lisa swayed gently as she walked up, patting Pingsi’s head. “Pingsi has studied my paper, ‘The Propagation of Lightning Force in Non-homogeneous Media,’ very thoroughly. I was the one who got his ‘first academic paper’… He provided a corrected formula that solved many problems.”

As a legendary high-level lightning element enchantment archmage, Lisa has indeed published many related papers, and she is a theorist. Although Yunxiu occasionally publishes some, they are mainly analyses of the spells themselves, which are mainly for teaching purposes. Of course, he has also studied the spells of Xiaoyue and Alice, but he knows nothing about the area that Pingsi studies.

"And then there's your paper, Father, 'The Hierarchical Structure of Protective Spells and the Existence of Solutions,' and Master René's 'The Mathematical Foundations of the World: A Unified Description from Ley Lines to Elemental Forces.'" Yun Ping thought for a moment, then continued, "There should also be Mother and Master Abedo's paper, 'Thermodynamic Limits of the Core of an Artificial Demon God and the Viscosity Problem of Three-Dimensional Incompressible Fluids'..."

After thinking it over carefully, he finally spoke up: "There shouldn't be any more. It's mainly these few papers. I will cite them when this paper is published, and then you, Father, will be the ones to review them for me."

Yunxiu looked at his son intently. With more than twenty children in the family, it was already quite an achievement for him to remember some of the important events of each of them. Pingsi had a very strong talent for mathematics and physics when he was three years old, and it was Yunxiu who personally took him to study with Abedo.

However, most of the time the child is at home quietly reading and researching. Occasionally he will come to ask me some questions. I only need to care about whether he is growing up healthily. The father and son do not talk much every day. When they do talk, it is mostly about academic issues. Pingsi's research direction is also relatively niche.

This is the daily routine for most mages and scholars. After all, once you reach the legendary realm, the difficulty of studying spells across different fields becomes unbelievable. Even for a genius like Yunxiu, this is the same. His high intelligence allows him to see and apply many spell runes, but that doesn't mean he can understand and develop them.

His magical abilities are mostly limited to defense and a portion of spells. Defense and anti-defense, or stripping, are his areas of expertise, while his offensive capabilities so far consist of only three legendary offensive spells.

“Okay, I will definitely try my best to find out the problems with the runes in terms of space and protection.” Yunxiu smiled and pulled Pingsi over, looking at the child whose strength was only around the fourth ring and said with a smile, “But today is a day worth celebrating. Let’s go home and have Xiangling’s mother cook you a good meal.”

Ping Si nodded, and Yun Xiu smiled and called out to the scholars around her, "Since it's a day worth celebrating, let's all come to my house for dinner today! Everything at Wanmin Hall is free today!"

"Great! I've been so busy, I haven't had a chance to eat the Goddess Chef's food!"

"Who can argue with that? I've been really confused by Miss Sugar's magic circle lately, but today I've finally seen the light!"

"This thing is a success! My paper can finally be published. Sigh, the Academy of Educational Sciences is now a 'publish or perish' system. With this paper, I can finally become a research fellow."

"By the way, which company did you invest in?"

"The Imperial Academy Gazette from Liyue has a very strict review process, and it's said that it's often reviewed by the immortals themselves, but the coefficient is high!"

"It's pretty good, but it's too difficult to get published. Even the Ramanaja Academy Journal of the Number Theory is hard to get published in. I just don't know where this article will be published."

"Of course it's the 'Academy Gazette,' after all, he's from Liyue... Hmm, Mondstadt's 'Alchemy Journal' also has a chance, many of the key introductions in this article come from Mondstadt."

A group of scholars boarded the shuttle ship in a noisy manner. Yunxiu also boarded the ship with Sugar and Pingsi. Soon they arrived at the entrance of the space elevator of Lingxiao Palace and quickly went down to Ochikanata. Yunxiu casually opened a space gate directly at the entrance of Wanmin Hall. Xiangling, of course, already knew about this news and had prepared food and was waiting.

Everyone was quite happy to celebrate the news together. Of course, Yunxiu did pay the bill in the end, and even the people who were eating at Wanmintang were exempted from paying. Wanmintang is quite large now, with seven floors that can accommodate thousands of diners at a time. Although this has brought in an expense of over a million Mora, it is nothing compared to the investment over the years and the results at this moment.

Sugar obtained the rights to the crystal ten years ago. However, the limitations of the crystal, particularly the "Death Slave Crystal," stemmed from two factors: firstly, its extremely corrosive nature; and secondly, the inherent properties of the crystal, particularly its ability to penetrate and destroy it. This limited the crystal's corrosive properties and its ability to effectively control the crystal's structure.

Teyvat's energy crystals are not actual minerals, but rather a renewable resource. However, they are difficult to collect. High-purity lightning element is condensed into crystals, requiring a powerful individual at the level of a lightning elemental god to collect them relatively easily. Moreover, due to the disorder of elemental forces, a single powerful individual can only collect a limited amount. Inazuma's annual collection volume is only tens of thousands of cubic meters.

However, with the storage bag, this problem changed. A powerful expert at the eighth or ninth ring level could mine several thousand cubic crystals a day if they wanted to. Under such circumstances, even if she used the Langya Sword, she could still obtain more crystals.

So Sugar has been looking for a better way. Four years ago, she finally managed to convert the energy liquid. Although the energy was huge, it was extremely unstable and could easily explode. After blowing up several devices, she moved her own device to space so that at least the explosion would not have too much of an impact. Occasionally, Firefly would help her clean up some of the mess.

She eventually managed to find a stable method and built new experimental equipment at the lunar base.

Preliminary tests were conducted, but the leakage and control of the energy liquid itself could not be restrained. Over the years, it has exploded countless times and hundreds of billions of Mora have been invested. Finally, Yun Pingsi found the last loophole.

Of course, the results are remarkable.

After Yun Pingsi's paper, "Global Well-Constant Properties of Three-Dimensional Resistive Magnetohydrodynamic Equations: Existence of Equilibrium State and Nonlinear Stability under Circular Magnetic Confinement Geometry," was reviewed and approved by several legendary and god-level powerhouses, including Xiaoyue, Alice, Abedo, Rene, Lisa, and the Great Tree King, a month later.

This groundbreaking paper was officially published in the "Taiyuan Journal," and as soon as it was published, it sparked a wave of excitement throughout Teyvat!

Chapter 468 The Myriad Phenomena of the Dao and the Future

Although many people cannot understand such a long paper title, once they see the solution to the mystery of the "Demon God's Energy Core", everyone understands the term.
