Former Sword Champion of the Luofu, and the creator of the Cloud Knights' legends of undefeated might.
Now her name has been wiped from the records, and she is a traitor of the Xianzhou walking on the fine line between sanity and mara-struck.

A sword, 3 feet and 7 inches in length, that weighs nothing.
It was not forged from any ordinary iron, but condensed from a shaft of sharp ice. It glowed with a dim light, as if it were a sliver of moonlight held in the wielder's hand.

“A sword, 3 feet and 7 inches in length, weighing about 7 catties. Hold it in your hand, and stab the sharp end towards the enemy.”
With a gentle flip of her hand, the woman in armor called her sword. As if alive, the sword leapt out of the weapon rack, sliding into her grasp and out of its sheath in one fell swoop. The blade then stabbed into the air beside the girl, humming intently.
“You got that yet? If so, go fight the most common war beasts the borisin use in their ground forces. Once you've killed ten Bloodshot War Wyverns, I'll consider your first lesson completed.”
She remained silent, her eyes daring left and right. This was her first time stepping out of the ward since being rescued, and the first time ever in her life she had touched a weapon known as a sword.
“I have dismissed the healers and helpers. They won't come to you without my orders.”
“The calamity in Cangcheng left few survivors. I don't know what you've been through before the rescue arrived… But I don't want to see you wallow in past horrors like this for the rest of your life.”
“It's okay if you don't wanna talk. You can speak with this.”
“You can use this to vanquish the monsters that took everything from us. There are now few things as wondrous as this left in the world.”
The woman in armor remained composed, her gaze cast onto the long sword by the girl's side.

The mirror-like blade showed her reflection. Then, a swarm of razor shards swirled up in a tempest, dragging the girl into her past —
In the dimly lit sky, the demonic planet named Rahu was wailing and singing, hurling towards everyone with lands and mountains ablaze.
On the streets, people were screaming, writhing and rolling in apocalyptic despair, as the golden tendrils sprouted and grew feverishly in every orifice of theirs.
She watched everything unfold, paralyzed. Her organs felt like they were boiling. Something suddenly surged and churned in her Core Esse, like a ripe wheat grain about to burst out of its husk and swell to infinity. The mountains hurling towards her face made her realize, she was but a mayfly, about to perish at the mere flick of an Emanator's fingertip.

In that split moment before death claimed her, she grabbed the only thread she could hang by.
A sword, 3 feet and 7 inches in length, weighing about 7 catties.

A sword, 6 feet and 5 inches in length, weighing 14 catties.
This is a Cloud Knight greatsword that must be wielded with both hands. Its edge contains enchanted fire that can split open the mechabeast's inert armor at the moment of contact.
There are 12 Flying Swords providing support, connected into her spinal meridian from the acupuncture points of Dazhui to Yaoyangguan. She needed only to think for these swords to instantly span out like a blistering storm.
She was still unfamiliar with the way of the sword. She still had lots to learn.

The woman in armor had no time to teach her more before the woman was tasked with leading the army on the field. Therefore, the girl's second lesson is to be learned on the battlefield, taught by the enemies she would fell.
“Stab” is easy, but swift monsters won't run into the sword's tip on their own or let the girl execute them. That is how she learned “slash.”
“Entangle” is next. Against monsters with overwhelming strength, the girl learned how to parry with the back of the sword to deflect enemy attacks.
She believed she had learned enough of the sword and therefore leapt onto the mechabeast war pawn “Gigantes” that dwarfed her at least ten times over.
She broke all the swords she brought with her and only managed to leave a few dozen cuts on the opponent's gigantic body.
She was whacked away by an enormous hand. Lying in the blood-soaked mud of the battlefield, she was once again swallowed by horror. In that split moment before death claimed her, she finally understood that even the art of swordplay had its limits.
An arrow filled with blazing fire flew off the Gigantes' head. “Get up.” The woman in armor looked at her.

“I don't want to learn the sword anymore. It's… useless.”
“Useless? It's pretty useful in my hands. It is the wielder who was useless.”
“…“
“If you don't want to learn the sword, what do you want to learn? The alchemical arrows on the pilots' starskiffs? The blazing fire flung by divine crossbows? Or… The artillery of the Zhuming Xianzhou? Such instruments would also be enough to destroy that demonic planet. You want to learn about them? Fine. Those things can kill the enemy even from beyond visual range.”
”… I just don't understand why you insist on teaching me the sword!?”
“From the general to the smallest pawn, every Cloud Knight starts by learning the sword.
The various constructs provided by the Artisanship Commission can certainly kill the enemy for you, but those deeds are to the merit of the material rather than the person. If there comes a day that the quivers run empty, that the starskiffs crash, that the aurumatons freeze — Who will protect you and I, then? Who will protect the Xianzhou?
Hold this sword. Remember, it would not be a true fight for humanity if Cloud Knights didn't wield swords and march onto the battlefield themselves. Rather than letting ingenia do it the work for us, we will show our final victory to those inhuman abominations by our own blood and prowess!”

The woman in armor turned and departed, leaving the girl and the broken sword in the training room.
A sword, 2 feet and 1 inch in length, only its broken fragments remained.
