Seeing the mention of the Firmament Nail in Su Xuan's diary,
the girls were all scratching their heads. Few knew what this thing really was or what it did exactly.
But the term [Divine Punishment] stood out glaringly.
Anyone could guess with their toes that this was punishment from Celestia upon the mortal world.
Across the sea, Raiden Ei's delicate frame shuddered violently.
Her gaze involuntarily turned toward Mondstadt.
Even separated by an endless ocean, she could feel the overwhelming pressure radiating from Su Xuan.
"Firmament Nail... He..." Raiden Ei didn't even know what words to use to describe Su Xuan, who was about to recreate the Firmament Nail.
Su Xuan's telekinesis was terrifying in its destructive power, no doubt.
But the Firmament Nail was the symbol of Celestia's verdict.
"For such a supreme symbol to be within his grasp so easily..." Raiden Ei murmured in a daze.
Fortunately, recalling Su Xuan's words—[Inazuma is yours during the day, but you're mine at night]—eased her tension a little.
"No, this isn't the time to think about random nonsense."
"I need to quickly join forces with Lady Miko to restore Inazuma to the right path. That way, when Su Xuan visits again, he can see my changes."
Dragonspine.
Two figures pierced through the swirling storm clouds atop the peaks, gazing down at the vast, majestic land below.
Eula sighed in awe, her heart deeply captivated by the freedom of soaring through the skies—a feeling she could only describe as romantic.
Legend had it that in Mondstadt, lovers sat under Starsnatch Cliff counting the stars, but compared to freely flying through the heavens, that was downright lame.
Of course, only someone like him with telekinesis could pull this off.
Glancing at Su Xuan nearby, Eula even felt the urge to take his hand.
Unfortunately, Su Xuan's full attention was on a stone pillar surrounded by floating debris.
Moments later, Su Xuan withdrew his hand from the Firmament Nail.
With a snap of his fingers, two identical nails—perfect and undamaged—suddenly hovered at his sides.
"Success?" Eula asked excitedly.
"Mm, success." Su Xuan nodded lightly.
Eula leaned in for a closer look, curiosity piqued. "You said this is divine punishment from Celestia. What exactly does it do?"
"I mean, how does it deliver the punishment?"
Su Xuan didn't answer directly, instead pointing at Dragonspine below.
"Do you know that the snow mountain under our feet used to be an ancient kingdom whose civilization was several times more advanced than modern Mondstadt?"
"Several times more advanced than Mondstadt?" Eula was stunned.
Eula, who frequented Dragonspine, knew it had once been an ancient nation—from the mountain steps and ruined buildings nearby.
She just hadn't realized its civilization was that superior.
"That's why this ancient kingdom ended up like this." Su Xuan pointed at the damaged Firmament Nail. "It happened in an instant."
Eula: "???"
[Firmament Nail (Celestia).jpg]
[After studying the Firmament Nail, I've successfully learned to recreate it.]

The girls all widened their eyes.
The two pristine Firmament Nails floating beside Su Xuan starkly contrasted the damaged one.
Scrolling further, the girls were so shocked they nearly wet themselves.
[As for what this thing does...]
[It can repair damaged boundaries of the Teyvat continent, mend Ley Lines, and suppress the Abyss.]
[Of course, it can also serve as a truth weapon to obliterate the land's surface.]
[Mondstadt's Dragonspine was once the highly advanced civilization of Sal Vindagnyr.]
[But the local priests misunderstood the immortal messenger's warning to protect the Silver-White Ancient Tree and not abuse it.]
[The priests thought the Silver-White Ancient Tree—a branch of the Ley Lines—was a gift from Celestia for their development.]
[So they built an altar beside it and harnessed Ley Line elements to advance their nation, reaching a level not inferior to Khaenri'ah.]
[In the end, Celestia dropped a Firmament Nail.]
[Sal Vindagnyr became Dragonspine.]
[And Sumeru's desert? It was once a rainforest—until a nail turned it into desert.]
[Teyvat's tech is pretty impressive, gotta say.]
[Even someone with the Authority of Lexicon like me can pick up some neat toys.]
[If a real fight breaks out, besides telekinesis, I can toss nails too.]
The girls: "???"
No wonder it was Celestia's [Divine Punishment].
The destruction it wrought on the continent was horrifying—one nail, and not just people and nations were wiped out, but the surrounding environment too.
Sumeru's desert had been barren for who-knows-how-many years, not a blade of grass in sight.
And based on Su Xuan's past feats and ability breakdowns...
His personal telekinesis grew stronger with him, scaling perfectly.
The Firmament Nail, however, seemed more like a technological product—Su Xuan's influence was on quantity replicated, not raw power.
Telekinesis was at least controllable by Su Xuan himself, while a Firmament Nail's power was fixed per nail—uncontrollable.
Tossing nails in a fight?
You'd wipe out everything around you!
Dear brother, just stick to your telekinesis, okay? At least it won't cause collateral damage.
Eula's beautiful eyes trembled as she stared at the two Firmament Nails orbiting Su Xuan.
If these dropped on Mondstadt, the city would become ancient history on the Teyvat continent.
Thankfully, Su Xuan only showed them off briefly before storing them away.
Then, he rubbed his stomach. "Haven't eaten since saving Dvalin. You hungry?"
"Let's head back and grab some food first."
Eula nodded eagerly like a pecking chick. "Okay... I have some food in my tent. I'll go prepare it for you now."
