The moment Su Xuan's diary mentioned the Skyfrost Nail, every girl reading fell into confusion.
Few truly understood what it was.
But the phrase "Divine Punishment" was impossible to miss.
Anyone with a brain cell could tell—it was something sent down from Celestia to punish the surface.
Across the sea in Inazuma, Raiden Ei's body trembled.
Her gaze lifted instinctively toward Mondstadt's distant horizon.
Even separated by a vast ocean, she could feel the suffocating pressure Su Xuan radiated while preparing to copy the Nail.
"Skyfrost Nail… he intends to recreate it?"
Even Ei, who once split islands and shattered gods, found no words to describe the magnitude of what Su Xuan was attempting.
Su Xuan's telekinesis was frightening enough—but the Skyfrost Nail was a symbol of Celestia's judgment.
For one to recreate such a thing…
"That such a sacred symbol rests in his hand as though it were nothing…" Ei whispered, momentarily dazed.
Fortunately—her mind steadied the moment she recalled his words:
「 In the daytime, Inazuma is yours.
At night… you are mine. 」
Ei's shoulders relaxed—if only barely.
"No. Now is not the time to think about… that."
"I must work with Miko to restore Inazuma—to show him, when he returns… that I have changed."
Dragonspine — Summit
Two silhouettes sliced through the swirling storm clouds atop the peak.
Below them, the land stretched vast and solemn.
Eula felt her heart lift—aching with longing.
This… this was freedom.
Not just staring at stars together on Starsnatch Cliff—this was romance you could feel in your bones.
Yet only he could do this—carry another into the sky as though gravity were beneath notice.
She dared glance sideways.
For the smallest moment, she wanted to reach out and take his hand.
But Su Xuan's attention was already fixed on the floating, shattered pillar of stone ahead.
The Skyfrost Nail.
A few quiet minutes passed.
Su Xuan finally withdrew his hand, then snapped his fingers lightly.
Two pristine, unbroken Skyfrost Nails materialized—one at his left, one at his right—floating in the air like fallen spears of heaven.
Eula's breath hitched.
"You… succeeded?"
"Mhm." Su Xuan nodded slightly.
"So… what exactly does it do? I mean—how does it punish?"
He didn't answer directly.
Instead, he pointed to the endless snowfields beneath their feet.
"Did you know that Dragonspine was once a nation?"
"A civilization far more advanced than modern Mondstadt."
Eula stared, stunned.
She knew the mountain was once a kingdom—but stronger than Mondstadt by several times?
"This land became what it is because of that."
He tapped the broken Skyfrost Nail.
"One strike. That's all."
Eula: "?"
Her diary lit up again.
Skyfrost Nail (Celestia).jpg
After analyzing it, I successfully reproduced it.
Skyfrost Nail (Mine).jpg
Every girl watching the diary froze.
The broken, ancient Nail hovering on the mountain—
and the two flawless new Nails orbiting Su Xuan—
the comparison was obscene.
And then the explanation came:
Its functions:
– Repairs the ruptured borders of Teyvat's world
– Stabilizes ley lines
– Suppresses Abyssal corruption
– …or serves as a planetary-level surface-erasure weapon
Dragonspine was once the prosperous kingdom of Sal Vindagnyr.
They misunderstood a messenger's warning:
The sacred silver tree was to be protected, not used.
They exploited its leyline power to accelerate national development—reaching heights comparable to Khaenri'ah.
So Celestia dropped a Skyfrost Nail.
The kingdom became Dragonspine.
The same happened in Sumeru—what was once rainforest became desert.
Teyvat's "technology" really is something.
With the Law of Reason, I might as well start collecting useful toys.
If I ever need to fight seriously—
I can throw Nails.
All the girls: "???"
Throw.
Throw.
A holy weapon that can erase entire nations—LIKE A ROCK.
No. Absolutely not.
Please.
Stick to telekinesis.
At least telekinesis won't accidentally delete a country.
Eula stared at the two Nails hovering near him, her heartbeat climbing.
If those fell on Mondstadt…
There would be no Mondstadt left to speak of.
Fortunately, Su Xuan dismissed them with a flick of his wrist.
Then, as if nothing earth-shaking had just occurred, he rubbed his stomach.
"Haven't eaten since I finished fixing Dvalin. Hungry. You?"
Eula nodded so fast her braid bounced.
"I—I have food in my camp. I'll… I'll prepare it. Right now."
