I'm in the Teyvat running group

Yunxiu glanced through the list and found that a total of 280 nine-ring level magic arrays and more than 800 eight-ring level magic arrays were needed, along with a large number of Returning Machines, soldiers, and materials. Among them were even a few special combat weapons—mechs!

"This mecha..."

The battle fortress requires constant maintenance and replenishment of highly mobile forces; this mech is designed for that purpose.

"Isn't high-intensity combat necessary?"

<The world's magic hasn't developed to a sufficient level yet; the ability to create this kind of mech, which is both repairable and combat-capable, already assumes the existence of an alchemy master.>

Okay, I know you're right, but this is way too expensive.

The entire magic array cost hundreds of billions of Mora to build, and a single mech costs tens of billions!

Even if you don't need to spend your own money, you still need to put in your own effort!

Moreover, Yunxiu looked at the dense layers of data on the mecha and the formation, and her head almost split open.

After carefully considering it in her mind, Yunxiu shook her head helplessly.

"Let's get people here. It's not easy for Inazuma to find a group of people who can understand blueprints."

As for where to start training, the answer to that question is already inevitable. Currently, apart from Liyue, no other country on the entire continent has established a complete training system.

Only Liyue could produce so many spellcasters.

Chapter 162 Night Palace Mecha at Triple Speed ​​(Second Update on Thursday!)

Therefore, four days after Yunxiu sent out the message, a group of students from the Imperial Academy, led by Kaiyangxing and Xiaoyue Zhuyang Zhenjun, arrived at Daozu.

As for the student leader, he was actually an acquaintance, Yunxiu's cousin Yunce.

After a few months, Yun Ce had become a mage of the Energy Shaping School in the Fourth Ring, and was considered one of the best among the students.

As for the magic arrays on the islands, Yunxiu has finished carving the basic structure in the past few days. As for some details, they can only be left to others to handle. Apart from the six core magic arrays, the other magic arrays are not difficult.

Yunxiu's most important task right now... is, of course, to build the war fortress.

In the past few days, he has sorted out all the blueprints, handed over the list to the three current officials to prepare supplies, and even made a special trip to Heguan to set up a teleportation array.

Although with his current strength he can't solve the problem of stabilizing the internal space of the human body during teleportation and can't teleport living beings, being able to teleport supplies already saves him a lot of effort...

The question of how to stabilize the internal space has been mentioned before; it involves legendary wishing techniques, and Yunxiu hasn't found a suitable method yet...

Large quantities of supplies were transported from Liyue and Winter Solstice. Liyue mainly received a large amount of data, manpower, and related rune materials, while Winter Solstice brought various ores, monster materials, and accessories.

The port on the outlying island was almost completely full, and the warehouse of the She Fengxing family was also piled up with a large number of precious materials. Thousands of nine-ring level monster materials were collected, including several legendary materials.

For Inazuma, this was basically a huge investment.

Of course, if you lose, you lose everything; only by winning can you recoup your costs.

Whether it's the Dark Outer Sea or the Sumeru Dead Zone, the forces that can be concentrated are limited in most cases. After this explosive attack ends, there will be at least a four- to five-month period of calm.

Therefore, when various countries provided aid to Inazuma, most of the supplies were sold or given away at half price, and the legendary powerhouses did not even mention any reward.

Of course, Raiden Zhen did open the treasure vault, allowing all the powerful warriors to choose freely.

However, the construction of the war fortress itself was actually the most difficult part.

Have any colossal structures ever been built on the continent of Teyvat? Of course, they have. Whether it's the Great Sun Chariot, the Crimson King's Tomb, or even the main city of Sumeru, they can all be considered super-colossal structures.

Even so, no war fortress of such enormous size has ever been built.

The only relatively close one might be the fortress built by the executive "Puppet" on the basis of the Lunar Force Laboratory during the Nordkale era, but its actual combat power was quite limited.

At least, they are far from being a match for Rael, who has not yet fully recovered.

There are just too many problems in building such a giant weapon of war.

The most pressing issue was energy. This problem was temporarily solved after several legendary experts moved the Yuying Furnace Core from Tasha to Heguan.

The Shadow Furnace Core is, after all, the energy core of the Demon God, and it is more than enough to provide energy for the war fortress.

Next came the main combat weapons, which, because it was a world of magic, were designated as the Returning Machine and a solidified charging array.

After discussing with several legendary powerhouses, they ultimately chose Yunxiu's [Meteor Fusion] and Gaoling Shuangyue's [Frost Moon Slash], mainly because both of them are energy-generating spells, which are relatively easy to use and have sufficient power.

【Frost Moon Slash】is a legendary combat skill, but Gaoling Shimotsuki has been studying it since childhood, so there is also a nine-ring version. It was quickly analyzed by Yunxiu, who also inscribed the relevant spell runes.

【Frostmoon Slash】Ninth Ring/Energy System

以一点为核心，向前方150米内释放出巨大的剑刃冲击，带来12D8穿刺伤害、12D8冲击伤害和15D10冰冻伤害，此伤害可叠加并且会对敌人造成75%减速效果。

If Takane Shimotsuki were to unleash a full-force sword strike, its power would be at least a hundred times greater, and its coverage area would be a thousand times stronger, making it undoubtedly a super-wide-range attack.

As for the output of the magic array, its biggest advantage is that it is tireless. As long as the charging speed of the magic array is sufficient, it is not a problem to release hundreds or thousands of magic arrays every day. At least hundreds of magic arrays can be deployed on a war fortress.

Besides [Meteor Fusion] and [Frost Moon Slash], there are also a large number of magic arrays with powerful burst capabilities, as well as legendary crossbows personally controlled by 'Genshin Impact' level powerhouses in the army.

With the addition of several hundred Return Machines and eight warships that have already arrived, the combined force this time is actually no less than that used to deal with Oser.

The deployment was also adjusted, and the four who were stationed on the front line of the Dark Sea were replaced by Minagi, Funina, Tsukihime, and Kaiyo.

The first three are all legendary peak powerhouses with formidable strength, and the main reason why Kaiyang Star is here is that he is the most skilled in commanding military formations, and can be said to be the only one in the entire Teyvat continent.

Yunxiu finally met the legendary Inazuma's strongest warrior, Gennagi.

To be honest, you can't really guess who it is just by looking at them...

Because she was simply a person, wearing a red robe and casually tied around her waist with a rope.

A silver-haired girl with a simple hair clip in her hair and an ordinary straight knife slung over her shoulder, who would be virtually undetectable in a crowd!

The only difference might be the two dog ears that droop diagonally over her head—that's right, she's a dog girl.

Even from the moment she entered her room at the war fortress in Heguan, she didn't utter a single word.

He would quietly come out to eat three meals a day, and spend the rest of his time meditating and practicing in his room.

"This person's personality is really interesting." Yunxiu said, looking at the first mecha that was gradually taking shape. "I wonder how she lives in Sumeru."

“Lady Nagi has always had this kind of personality. It is said that she was a yokai who followed Lord Kitsune-no-miya back then.” Sasa Yura, who was helping Yunxiu inscribe runes, said, “Since she has fewer and fewer friends, she has also started to speak less and less.”

"Lifespan..."

"But Lady Nagi is actually quite mentally healthy; she just doesn't like to talk."

"Oh...it's done."

With the last rune engraved, the main body of the mech was almost complete.

Yunzhi provided many different designs, but Yunxiu, with a rather wicked sense of humor, chose one that resembled Gundam and made some minor adjustments.

So after this mecha was built... it really did look quite like a Gundam.

However, this mecha is much larger than Gundam, reaching a height of over thirty meters. In terms of size alone, it is only slightly smaller than the three giant mechas of Sumeru, and not much different from the Twenty-Year Eternal Calamity Dragon Beast.

The materials were made from the body parts of a large number of level 8 or 9 monsters, and the energy source was modified from the perpetual core of the Eternal Calamity Dragon Beast. Three of them were used to ensure long-term combat.

In terms of operation, Yunxiu chose a mind control-like mode. The person does not actually need to move or press the control lever. They only need to touch the two crystals embedded next to the cockpit and think about them.

The weight reached more than 700 tons. In order to make it fly, Yunxiu specially studied the flight mechanism of the Eternal Calamity Dragon Beast. The final choice was to activate the floating stone and adjust the direction using the flight mechanism.

As for combat ability...

This mech only has basic self-defense capabilities and is equipped with only two sets of offensive magic arrays and a greatsword. Of course, dealing with ordinary level 7 or 8 monsters is still a piece of cake.

Its advantages are excellent mobility and protection capabilities, and its two robotic arms are very flexible, making it convenient to perform maintenance and rescue tasks in high-intensity combat.

As for who was the driver of the first one...

Xiao Gong had already volunteered himself a long time ago.

"Xiaogong! Xiaogong! The test is ready!" He shouted to the girls who were still chatting nearby.

"Here I am!" Xiaogong rushed over quickly, and seeing the mecha in front of him that had been painted in red and orange, he jumped into the mecha's control room with a whoosh: "I'll give it a try!"

"Okay... Now we'll proceed with our first simulation project: battlefield emergency repair." Yunxiu glanced at the design drawings, made a slight adjustment, and then sent the information to Xiaogong via the locally deployed local spiritual realm:

"Next, I will deploy a batch of magic arrays to launch a full-scale attack on you. You need to repair the seventh and ninth points under the siege... Repair instructions are on the next page."

"Hehe, of course, no problem!"

With a slight shudder, the mech's eight thrusters on its back activated at full power, unleashing a burst of orange-red flames that shot more than three meters away, instantly accelerating the mech, which had just flown out of the tunnel, beyond the range of a sonic boom!

Yunxiu couldn't help but marvel at Xiaogong's wildness. Accelerating from zero to over 200 meters in less than 50 meters—that must be 30G of overload...

Only Teyvats could withstand such violent acceleration. If it were an Earthling, they would most likely be crushed into mincemeat, becoming a true Yoomiya-chan...

Xiaogong also demonstrated excellent mecha piloting skills. The orange-red mecha charged left and right amidst the encirclement of dozens of magic arrays. The eight nozzles behind her and the two nozzles under her feet constantly and flexibly challenged the direction, allowing her to draw a beautiful arc in the air and cover a distance of more than ten kilometers in less than twenty seconds!

After reaching the turning point set by Yunxiu, the mech performed an aerial somersault, reversed its thrusters, and charged back.

Despite weaving through a sky full of spells, Xiao Gong didn't even get a single spell near him.

In fact, when Yunxiu designed this mecha, he piled up its protective capabilities to an extremely high level, so that even if several nine-ring spells were fired at once, it would not have much of an impact.

But unexpectedly, this girl was actually a true genius pilot, able to bring the performance to near its limit on her first try!

After quickly pulling back and forth a few times, the mech seized a gap in the firing and hovered outside the seventh position. It used both hands to pop out the rune repair mechanism, directly removed the broken rune plate and replaced it with a new one, and quickly performed a welding operation.

Then, she repeated the same move, another extremely powerful turn and shuttle, almost pushing the mecha's performance to its limit, and then, seizing an opening, repaired the ninth position.

After the repairs were completed, the mecha gave a slight jolt, and Xiaogong roared at full speed toward the warehouse on Yunxiu's side. It then made a skillful emergency stop on the ground, bringing the mecha to a steady stop at its starting position.

"Fun! So much fun!" Xiaogong skipped and jumped out of the control room, landing directly in Yunxiu's arms. "Can this only be used in this war? Is it very expensive to make?"

"Um... if you like it, I'll build you one after the war is over, one that's even bigger than this one."

Really? Really?

"Of course it's true." He patted Xiaogong's little face affectionately, then put her down and said, "Alright, you should familiarize yourself with the fortress a bit more. In a few days, it will be your time to show your skills. Right now, I need to continue building."

"Hmm! So what's the name of this first one?" Xiaogong asked curiously.

“Hmm…” Yunxiu glanced at Xiaogong and said:

Let's call her 'Fireworks'.

Chapter 163 Ripples in the Void Sea (Third update on Thursday!)

Manufacturing mechs is actually difficult at the beginning, but once you get started, it becomes much easier.

After testing the first mech to its limits at Xiaogong Palace, Yunxiu roughly estimated the capabilities of this repair mech.
