I'm in the Teyvat running group

The group turned their gaze to the enormous engineering mech, which stood tens of meters tall, had four legs, and a huge support frame trailing behind it. The mech's chest had a transparent cockpit, inside which was a rather handsome young man from Fontainebleau, who skillfully brought the mech to a stop.

Several eight-legged mechs carried up several oversized components and firmly secured them to the huge support behind him.

"Four base pieces. Is there anything else I need to bring?" Lu Xi'an checked the integrity of the rear components and smiled at today's liaison: "This should be my last time coming up here today. This thing is a real hassle to break through space once."

"That's all. Remember to come early tomorrow. We need to transport a new batch of supergiant space anchors." The liaison smiled, then looked at the young man and joked, "You drive this thing back and forth between heaven and earth every day, and your old man Ives hasn't said a word to you?"

"A space fleet is still a fleet... Besides, isn't this more interesting than sailing a ship?" Lu Xian laughed as he activated his mech, and the six massive thrusters began firing at full power. He left with a boastful remark: "See you tomorrow!"

The massive engineering mech sped through space like a streak of light, its speed increasing rapidly. Half an hour later, it reached the edge of the atmosphere. With a few quick presses of buttons, a force field spread out from the mech, firmly enveloping it.

With all six nozzles at full power, the mech immediately charged straight down towards Teyvat!

The immense power and gravity acted simultaneously, and the powerful weight pressed down on him, but it was nothing out of the ordinary for this already legendary young man. He even had the leisure to watch the flames burn a series of red streaks across the force field, making his face flush red.

boom--!

After a series of decelerations at the end, the mech crashed straight into the large lake in Fontainebleau.

Then you can see the support structure at the back transform, and the entire mech turns into a huge transport ship, quickly heading towards the port not far away.

Upon reaching the port, Lü Xian drove the engineering mech ashore. After several eight-legged engineering mechs unloaded the cargo, he drove this behemoth to the side of the launch pad.

There haven't been many opportunities to rest lately. I have to get up early tomorrow morning and continue flying, twice a day.

The only good news was that he didn't have to handle maintenance and refueling. As soon as the car stopped, dozens of engineers rushed over to check the magic array and export the engineering data. Then another transport psionic vehicle came over, inserted the energy interface into the fuel tank, and barrels of No. 7 energy liquid were continuously added in.

"The cost of one flight of the energy liquid is 20 million Mora. Fortunately, it is wartime now..." Lu Xi'an shook his head, went to the bathroom to take a shower and change his clothes before going to the canteen to eat.

He got two bowls of food, picked up a few large loaves of bread, and collected his daily ration of alcohol before starting to eat.

During the war preparation period, logistics management was almost the same as during the war itself. However, there was still the benefit of having demons and immortals cook for us. These dishes were still prepared by Huang Ming and Xiang Ling and transported in a unified manner through a spatial array.

Of course, if it's a special meal during a mission, then it's not mealtime, so you can only eat the food prepared by Xiangling's disciples, which is still quite good.

"Starting tomorrow, you might have to make an extra trip to the lunar base." A voice suddenly rang out from across the table, and at the same time, a plate landed on the table.

"Sister Zhilin? Shouldn't you be at the Liyue headquarters these days?" Lu Xian looked at the person in front of him, who was actually the second-in-command of the Chamber of Commerce, with curiosity: "Is there anything important at the lunar base?"

“We only have four of these special transport mechs. Two of them will be deployed to the front lines in Pohyura tomorrow to transport special supplies.” Zhilin first downed a bottle of soda before continuing, “Starting tomorrow, you will also be responsible for transporting special supplies from the ground to the lunar base. This means you will have to go from the lunar base to the space station and then back from there.”

"That's quite a long way to go." Lu Xi'an raised his hand, making a triangle in the air, before saying with a hint of helplessness, "I originally thought this was an ace pilot, someone who would be on the front lines, which is why I signed up, but I didn't expect him to be transporting all sorts of large items every day..."

"How many people can you kill on the front lines? Even ace pilots like Inazuma mainly work with the maintenance team to maintain the battlefield..." Zhilin rolled her eyes at him: "Besides, these special transport mechs are ridiculously difficult to manufacture. The cost of each one is almost the same as my armor. You were selected because you are truly outstanding, but you also benefited from your father's influence."

Zhilin wasn't angry. Ives was a good person, and his son was well-educated. But these transport mechs were difficult to manufacture, and they were indeed important strategic equipment.

As mentioned earlier, Teyvat cannot build rockets, and many large supplies cannot be put into storage bags due to various special reasons, which directly leads to the inability to transport them via the space elevator, and even demigods cannot go there.

Putting everything else aside, it's questionable whether a demigod could withstand tens of thousands of tons of supplies without using the "Heaven and Earth Transformation" technique...

Ultimately, the only option left was to build this special transport mech. Its nozzles do not spew out flames, and strictly speaking, the jets are not rocket engines, but rather peculiar products ejected after activating particles.

This also resulted in the ejector and activation device being extremely difficult to manufacture, requiring a large number of completely different advanced technologies, and to date there are only four units.

This is a super mech that can pass through the atmosphere and the false sky and move freely in the universe!

Using this thing in war would be a complete waste!

"Alright, alright, I surrender." Lu Xi'an cupped his hands in a gesture of respect. "I'll set off first thing tomorrow morning."

“That’s how it is during the war preparation period. Once the war starts, things will actually be easier for you.” Zhilin rubbed his head vigorously. “At most, we’ll just need to replenish special supplies… well, maybe not.”

"It's better than releasing floodwaters, isn't it?"

"If things are still not as good as they were back then, wouldn't all these years of construction have been for nothing?"

"That's true. I heard that my dad didn't take a bath for five days back then."

"If your father hears you say that, will you still be able to drive tomorrow?"

Lu Xi'an didn't argue. After finishing his meal, he put his plate in the recycling area. Before leaving, he continued to pass by Zhilin and left two beautiful Patisha orchids.

Zhilin was taken aback. She picked up the two flowers, only to find a small card underneath.

"Sister Zhilin, now that the fight's over, how about we consider my suggestion from last time?"

“I’m fourteen years older than you…” Zhilin sighed, but still quickly put away the card and Patty Sharan.

Next, she still has to see Yunxiu. If her master finds out, she'll probably be bombarded with nagging about marriage again. She doesn't know when her master picked up this habit.

He couldn't share his marital happiness with his apprentices... so he turned into a marriage-urging expert.

"But speaking of which, Master's wife seems to be several hundred years older than him... Uh, why am I thinking about this?" She quickly finished the food on her plate, then swiftly returned to her office to organize all the information before crossing the spatial portal beneath the Fengdan Chamber of Commerce headquarters and arriving directly at the backyard of Wanmin Hall.

As soon as I arrived, I saw Yunxiu and Yanfei eating and discussing things.

The meal was simple for the two of them, but Yunxiu's children were also eating with her. When they saw her arrive, they all looked up and greeted her.

"Zhilin, have you eaten yet?" Yunxiu ate as quickly as ever. He smiled at Zhilin and said, "If you haven't eaten, you can have some too. Don't be so tense. The success or failure of the war doesn't depend on this."

His eyebrows twitched suddenly, and he looked at Zhilin with some curiosity.

"Why do I feel like there's other people involved... Is it because I'm in love?"

Yunxiu stood up excitedly: "Come quickly and tell Master, which family it belongs to..."

"Master, let's discuss the deployment of the mech forces first..."

Chapter 532 A Thousand Years of History: The Transformation of the Land

"We can talk about the deployment later, why wouldn't I trust you?" Yunxiu waved her hand with a rather gossipy air: "None of you disciples are getting married or dating, even Pingyan has a little fangirl recently, I've even met her once..."

"Master! Let's talk about work first!" Zhilin angrily threw all sorts of documents on the table. Yunxiu chuckled and didn't press her disciple any further, which finally put Zhilin at ease.

“Our current deployment is still being adjusted gradually. However, as the preparations for the early stages of the war progress, a large portion of the equipment needs to be transferred to space.” Zhilin handed over several documents, pointing to a few of them and saying, “In addition, there is another very important matter: the number of heavy transport mechs is still too small. Once a high-intensity war breaks out, it would be best to build two or three more.”

"This thing is hard to manufacture, and the materials were sourced from several planets... I'll try to find a way to squeeze in enough materials for two engines." Yunxiu sighed. The engine core with its ultra-stable particle activation technology is extremely difficult to manufacture.

It's not that there's a problem with precision manufacturing. Teyvat's current level of precision manufacturing is already very high. If we were to use the standards of the original world, the precision would have already reached the 100-picometer level. What does that mean?

If you were to create a sphere, roughly the size of a baseball, that you could hold in one hand, and then enlarge that sphere to the size of the Earth, the difference between its highest and lowest points would be about 16 millimeters.

What does this mean?

For a typical residential building, the allowable tolerance between the bases of the columns is 5 millimeters...

The problem is that once technology enters this field, the gap often becomes not a matter of technology, but rather involves the underlying principles themselves.

The internal conditions and elementalization of the False Heaven made it impossible to manufacture many things. Although this could be barely resolved in the short term, transporting things was even more impossible. Ultimately, with the combined efforts of two of the world's top alchemists, they developed an ultra-stable particle activation technology.

The principle behind this thing is actually quite unbelievable. This core can convert high-energy particles and eject energy, but it is extremely stable, so stable that it will not react at all in the environment of the abyss and the ethereal light realm.

Only by using specific laws and special forging methods can it be processed into an energy core. To date, only one top-tier demigod mage possesses these laws—Anya.

In other words, the processing method for this material only exists in stories; it is a purely conceptual product, which directly leads to extremely low production volume.

Using such precious materials for protective equipment would be too wasteful, so their main uses are twofold: one is to manufacture the core of this super mech, and the other is to manufacture the outer shell of the probe used for internal exploration in Poheyura.

However, Anya's strength is growing stronger and stronger. As her new stories begin to spread, she writes many strange and wonderful stories. The laws and powers derived from these stories are fed back into her, making her strength much greater.

"Then there's the maintenance of the mech units. Although there are over a thousand now, they're divided into two batches. This is because we didn't consider space warfare when we designed the first batch, so the logistics department suggested that the entire first batch be phased out and used to fill the gaps in the second-line units." Zhilin opened another document: "Manufacture the second generation to replace them all. That way, it'll be cheaper."

"You can decide these things. There's no need to talk about funding now. We'll settle everything after the war." Yunxiu nodded, then took out a small gadget from her storage bag and handed it to Zhilin: "Here, take this. I just figured it out recently. It comes with the effect of an Eternal Pure Land, which can keep you in top condition... Don't overwork yourself."

What he handed to Zhilin was a divine artifact he had solidified and refined himself. It wasn't anything particularly precious, costing only a few hundred million Mora. What was expensive was the solidified Eternal Pure Land and a series of spells, but it was nothing to him anymore.

Zhilin took the artifact without saying much. Her master often made these kinds of things, so she was used to it.

After seeing her apprentice off, Yunxiu stretched and took a rare stroll in Liyue Harbor with Xiangling. They hadn't walked far when they saw the sign for "Natasha's Kitchen." The proprietress, Katya, was making something at the entrance with a two- or three-year-old child.

Katya chopped up a large amount of beef and threw it into a pot to stew. Then she added all sorts of vegetables, beans, and sauces, stirring it up until half the street was filled with a strong aroma. The red broth contained large chunks of chopped beef and vegetables, and was stewed into a big pot of thick soup.

She ladled out the thick soup and put it into large tin cans. After sealing them, she affixed talismans for "constant temperature preservation" and "sterilization." After putting the large tin cans into a storage bag, the proprietress dragged out half a slice of beef from the kitchen, cut it up, and threw it into the pot to begin the preparation of the second batch.

"Boss lady, are you making canned 'Red Flavor Soup'?" Yunxiu smiled as she watched Katya bustling around, showing no surprise.

Although standardized production by logistics departments is the least labor-intensive, Yunxiu also allowed some private merchants to participate in the production of logistics meals. However, it was subject to an approval system. After they passed the approval, they would receive ingredients, talismans, and utensils from the logistics department to make the meals. Once the meals were made, they would be packed up and sent to the front lines. Settlement would be made after the battle.

These meals may not play a significant role in the same way as other logistical support, and may even require more effort, but Yunxiu believes they are necessary.

If soldiers are fighting on the front lines and civilians are only left in fear or working in factories, then their value becomes questionable. Letting them do what they can within their capabilities, and then having the government coordinate their efforts, might be the best option.

Putting everything else aside, for the soldiers on the front lines of Zhidong, after finishing the battle in the Abyss, eating the authentic red-flavored thick soup canned by the proprietress of Zhidong must be much warmer than eating the Fishy Chanting Party, right?

Although the nutritional value may not be significantly different.

"True Lord Yunxiu, you've arrived." Katya smiled as she watched Yunxiu approach. She then scooped up a spoonful of food, poured it into a bowl, and handed it to Yunxiu. "True Lord, please try it. Although it's a bit of a show-off in front of Miss Xiangling, it shouldn't be too bad."

“I think Xiangling’s red broth might not be as good as the proprietress’s.” Yunxiu smiled, took a bowl, tasted it, nodded in satisfaction, and then handed it to Xiangling before turning to ask, “Ristor isn’t here? I remember it shouldn’t be time to call up the reserves yet, and the training has only just begun.”

“He’s a restless person. He went to discuss with his old comrades whether to mobilize the reserves to form a transport team first.” Katya sighed helplessly as she stirred the mixture. “Nowadays, heavy transport trucks require both strength and technology. Although the number of vehicles being transported is a hundred times greater than before, the logistics department was still recruiting a few days ago.”

Yunxiu nodded. That was true. Nowadays, most heavy-duty spirit frames have self-loading and unloading capabilities. Moreover, because they directly inherit the storage device, transportation requires not only sufficient strength but also a certain level of technical expertise.

Generally speaking, one needs to be at least at the fifth level, and it takes one or two years of training to get started quickly; to do that would be legendary.

However, most soldiers in the reserves and regular forces need to master emergency response capabilities, so most of them already have a basic understanding. With some training, it is entirely feasible to deploy them to transport units.

He didn't ask any more questions, but gave a few more instructions before continuing to walk with Xiangling. Many other merchants on the street had also joined in this logistical support work.

At night, several spirit wagons would come to conduct unified audits, inspections, and record-keeping before loading them onto the wagons and sending them to the front lines. This wasn't just happening in Liyue; many other countries did as well.

Xiangling is now a high-level legendary expert. Under Yunxiu's influence, those around her with even a little talent can now reach this level. Those with real talent, like Qiliangliang, have already climbed quite a distance to the peak of the legendary realm.

So the two of them walked at a seemingly slow but actually fast pace. In less than half an hour, they were already standing on Mount Tianheng, looking down at Liyue Harbor.

"Now I understand why the Emperor often stands here watching over Liyue. It's quite poignant." Yunxiu looked at Liyue Harbor, which had expanded considerably in the past ten years, and the bustling, vibrant world around it, and said with some emotion, "Back then, my goal was just to get married and see if I could survive the apocalypse. I never expected..."

"Xiuxiu, did the end of the world really come back then?" Xiangling was somewhat surprised. This was the first time Yunxiu had spoken so lightly about such a heavy topic. "Weren't the Battle of Osel and the Flood Discharge War considered real major battles?"

“The scale of the flood discharge may be similar to that of the Battle of Kanria, but the battle we are fighting now is even larger than the Burial Fire of ancient times.” Yunxiu pointed to the large array above Liyue Harbor and said, “The Burial Fire tore the world apart, and repairs have not solved the problem. Many things that happened afterward were actually just cleaning up the mess left by someone back then.”

"Now, I've finally finished cleaning up. After I take care of this last piece, I should drag her out and beat her up. At least she'll have to pay some price."

"It feels like I'm talking about a disobedient child." Xiangling shook her head with a smile. "But, Xiuxiu, there's something I've always been curious about: how exactly did things develop from ancient times to the present? The Emperor often doesn't like to talk about it, and you haven't said much either..."

"Now is not the time to keep secrets anymore, since we've come to the last minute anyway. We need to go back a long time to this issue..."

Yunxiu stood on the platform with his hands behind his back and began to tell the story of ancient times little by little. This was the memory of the entire Teyvat past that he had finally read together with his previous clone after he severed his human avatar.

"Many records are vague, and many stories are told in a rather obscure way. We must start from the most ancient times. Where did the world itself come from? The answer is light."

"Light gave birth to the primordial fire, which then gave birth to seven elements. These seven elements constituted the world, and at the pinnacle of the elements were the seven giant dragons—Tuozi was one of them."
