The sea outside Liyue was turbulent.
The Guizhong Ballista's attack had completely enraged Osial.
Its five heads simultaneously raised, gathering an energy ball from their mouths together.
The blue-white energy ball illuminated the entire sea, which was shrouded by dark clouds.
Lumine was still live-streaming, her face showing her signature silly and innocent look.
[Uchiha Madara: "It's very powerful; even through the screen, there's such a strong sense of oppression."]
[Zeref: "Indeed, it's no exaggeration to say this power belongs to a god."]
[Lumine: "Aside from its appearance, Osial's strength is among the strongest of the Gods. Even a tiny leak of its power isn't something Liyue's Adepti can easily suppress."]
While Lumine was speaking in the Chat Group, Osial shot the gathered giant energy ball towards the sky.
Like a terrifying laser beam, it pierced through the entire cloud layer, making the dim sky as bright as day.
A moment later.
The sky shimmered with a brilliant blue light.
The energy Osial shot into the sky transformed into countless Hydro-elemental light arrows, falling like meteors towards the ground.
The first to bear the brunt was the Jade Chamber floating in the sky.
Countless water arrows struck the Jade Chamber, causing explosions.
With the array's blessing, the Jade Chamber's defenses were still strong, but the Guizhong Ballista used to counter Osial was completely damaged. The Liyue Millelith guarding the Guizhong Ballista had no choice but to retreat from the outside to the inside.
As the outer array shattered, Aether missed his footing.
"Brother!"
Lumine gasped, her body transforming into a golden light as she flew towards the Jade Chamber.
On the other side, Xiao saw Aether lose his footing and fall. He leaped a few times, intending to catch the falling Aether.
"Hm?"
A golden light streaked past him, and Aether vanished in the blink of an eye.
"That was just now..."
The direction the light flew was precisely toward the Jade Chamber.
Xiao was silent for a moment, then vanished from his spot.
The golden light surrounding Lumine disappeared, and Lumine, carrying Aether, had already arrived at the Jade Chamber.
"Long time no see, Brother," Lumine said.
Aether's eyes were filled with disbelief, and his shoulders, held by Lumine, trembled slightly.
"You are... Lumine?"
"It's me, no doubt about it."
Lumine smiled, and that smile felt familiar to Aether.
"The rest, let's talk after Osial's matter is over. Now isn't the time to discuss this."
In the Chat Group.
[Kumoko: "Eh? @Lumine, are you going to help your brother?"]
[Lumine: "No, this is his journey. I just instinctively saved Aether. I already regret it."]
Watching her brother lose his footing and fall, Lumine unconsciously had the urge to save him, but after catching him...
Her mind was like, 'What the heck?'
'Where is this?'
'What am I doing?'
But, since she had already saved him, she couldn't just let go and drop him, could she?
No matter what, he was her blood relative.
Helpless, Lumine could only bring Aether back here first.
[World's No. 1 Princess: "Lumine, what are you going to do next?"]
In the Genshin Impact plot, this didn't seem to happen, or maybe Lumine wasn't on the scene at the time, so she didn't save Aether, allowing Xiao to succeed.
[Lumine: "I'm not going to give up. I don't believe Morax would dare to drag Liyue into a fight to the death with me just for a mere Osial."]
[World's No. 1 Princess: "..."]
You're very short-tempered, Lumine.
After Lumine saved Aether, she didn't wait for Aether to ask anything.
The people of Liyue had already gathered around.
"Traveler, this is..." Ningguang looked at Aether, then sized up Lumine for a moment.
"My sister Lumine. I've been looking for her because we were separated before," Aether replied.
"So it's your sister." Ningguang had thoroughly investigated the Traveler's information and knew that when Aether was in Mondstadt, he had asked the Knights of Favonius to post missing person notices.
"Lumine, it's a pleasure to meet you." Ningguang was very interested in Lumine. Putting everything else aside, being able to save her brother in such a situation just now already demonstrated her strength.
Seeing Lumine nod without speaking, she found it difficult to strike up a conversation.
Ningguang also knew that now was not the time for such things; no matter how curious she was, she had to deal with Osial, who was blocking their way, first.
Lumine had no intention of interfering with Aether and Liyue's affairs.
After saving Aether, Lumine turned and flew down from the Jade Chamber under everyone's gaze, waving her sleeve without taking a single cloud with her.
Osial let out a long, piercing dragon roar, emitting a deafening sound wave that made people's ears ache.
Seemingly seeing the solitary Lumine, one of Osial's snake heads opened its mouth.
A hydro-blue energy beam shot straight towards the direction Lumine was descending.
"Lumine!"
Aether's face turned pale with fright at the sight.
However, Lumine had already flown too far, and even if Aether wanted to save her, there was nothing he could do.
"Hmph—"
Lumine sighed, "Do you really want to be caught that badly?"
A slender sword with golden patterns appeared in Lumine's hand.
She casually swung it at the incoming beam.
In an instant, Osial's attack was dispersed.
The next moment.
Boom!
Osial, who originally had five heads, had the head that attacked Lumine, including its body, directly explode.
"W-wah~"
A mournful cry came from Osial's direction.
Lumine did not continue to attack Osial; the sword in her hand disappeared.
She continued to descend towards the ground.
And this scene was fully witnessed by everyone on the Jade Chamber.
"That weapon... has Lumine regained her strength?" Aether's murmured voice carried a slight tremor.
Moreover, Aether vaguely felt that Lumine's current strength might be even greater than when she fought that god.
"A casual strike, and it has such power?" A flicker of surprise flashed in Xiao's eyes.
When he went to save Aether just now, he felt the aura from the Traveler's sister up close.
That suffocating feeling, he had only ever experienced from the Geo Archon.
Everyone hadn't yet recovered from Lumine's terrifying power.
But Osial began to attack, having one of its heads directly obliterated completely enraged it.
It couldn't find Lumine, so it could only vent its anger on the conspicuous Jade Chamber in the sky.
"Fellow Adepti, now is not the time to overthink..." Seeing Osial's fury, Ningguang spoke up to draw everyone's attention back.
Ningguang continued to explain the 'Falling Jade Chamber' plan to everyone.
Osial, having lost one head, was slightly weaker than in the original story.
After everyone made their arrangements.
The Jade Chamber fell, accompanied by a terrifying crash and Osial's mournful cries.
On the surface of the sea, a giant mushroom cloud slowly rose.
Osial was sealed once again.
After the matter concluded, everyone returned to Liyue Harbor.
"Brother, you've worked hard," Lumine said to the returning Aether.
Since they had already met, there was no need to use the original plan to send him away.
"Lumine, you..."
"Whatever you want to say, wait until you've traveled through the Seven Nations. I'll be watching you," Lumine interrupted Aether.
"Then, farewell."
Behind Lumine, an oval portal appeared.
"Wait, Lumine!"
Aether reached out, trying to grab Lumine, who was about to enter the portal.
"We will meet again, but not now..."
Lumine's figure disappeared, and the portal began to fade. Aether's outstretched hand passed directly through the portal to the other side, but failed to enter the portal.
