If Bai Yu hadn't already gone through one transmigration experience, he wouldn't be as calm as he is now.
The moment his sword heart broke through to the Wuchen realm and entered the Mingjing realm, his consciousness was pulled away from his body by a force, then crossed the world barrier and arrived in Teyvat, possessing the Traveler Lumine, who had just entered Mondstadt.
Fortunately, Bai Yu quickly sensed his own body and discovered that there was still a faint connection between his consciousness and his body. He could clearly sense that his body was still sitting cross-legged on a cushion, and he breathed a sigh of relief.
His current state was like having a very clear dream. He was aware that he was dreaming, but he still had a faint perception of his physical body in reality.
The connection between his consciousness and his body was faint, but Bai Yu was able to instantly distract himself to control twelve flying swords. With this thread of connection, which seemed like it could break at any moment, Bai Yu tried to return his consciousness to his original body, only to feel the same pulling force again.
He finally felt relieved and temporarily suppressed the urge to return.
After briefly guiding Lumine with a few words, Bai Yu began to silently study his current situation.
While fighting against the Stormterror, Lumine couldn't help but have various thoughts. Her confusion about the current situation, her curiosity about the voice (Venti) she heard earlier and the voice's owner in her mind, all these thoughts were not hidden from Bai Yu's perception.
Bai Yu tried to silently communicate with Lumine in his mind, but he didn't receive a response.
(So, is this open-minded thinking one-sided?)
(Is it because I am the 'possessor'?)
(Furthermore...)
Bai Yu realized that even though his consciousness possessing the body prevented him from bringing his physical strength, the transformation of his body from the sword heart condensation and the absorption of destiny power was comprehensive. This transformation naturally included his consciousness and soul.
As luck would have it, the Great Void Sword Qi didn't focus much on the sword moves themselves. It prioritized the cultivation of the sword heart and the realm, which were brought along with his consciousness.
Just as he thought this, Bai Yu heard Lumine's plea for help.
Surprised that Lumine didn't follow the plotline he remembered and let Stormterror escape, instead asking for his help to capture the dragon, Bai Yu reacted quickly and said:
『Simple, if you really want to capture Stormterror, just give me your body.』
"What…what do you mean give you my body—Oh, oh, oh, oh, oh!?!?!"
Before Lumine could be surprised by Bai Yu's words, which were easily misunderstood, she was shocked to discover that her body had become uncontrollable!
The girl was momentarily stunned, and Bai Yu took control of her body.
In the sky, Bai Yu didn't expect to take control of the body so smoothly. He simply thought about it, and he successfully "logged in."
With a little thought, Bai Yu understood the reason.
"Is it because my sword heart is condensed, and my mind is strong, while Lumine's power has been sealed, lowering her resistance in this area?"
"Lumine? What are you talking about!?"
Paimon cautiously looked at her traveling companion, who had suddenly become unfamiliar.
Just now, Lumine had mumbled to herself, and her expression had changed drastically.
Bai Yu glanced at Paimon and smiled, stroking her head with his slender fingers, his lips slightly curved in a charming smile: "Hello there, emergency food."
Paimon: "——!!!!!"
At the same time, due to Bai Yu's "login," Lumine's consciousness retreated to her mind, where she could only share her five senses with Bai Yu and completely lost control of her body.
(What's going on!?)
(You're controlling my body!?)
(Who are you!?)
(Give me back my body!)
"So noisy…be quiet. Didn't you say you wanted me to help you capture Stormterror?"
Bai Yu used his finger to scratch his ear. This rather unladylike action made Paimon dumbfounded.
She vaguely sensed that something was different inside Lumine.
(I…I don't need your help anymore QAQ, just give me back my body!)
"That's not possible." Bai Yu pursed his lips, "It's not that I have to help, but I just want to use this opportunity to do an experiment…uh, is the Prototype Amber still there? Good, but it doesn't matter if it's not."
Bai Yu curled his lips, staring at Stormterror, whose form was now a small figure. He casually stretched out his hand, and the Prototype Amber appeared in his hand.
"Where the heart reaches, everything in heaven and earth can be a sword!"
In an instant, Bai Yu (Lumine?) retracted his wind wings, but his (her?) body didn't fall down. Instead, he (she?) stood firmly in the air.
The wind stopped.
The entire world became incredibly quiet in an instant.
On a distant mountain ridge, Venti's pupils shrank to the size of pinpricks.
In his line of sight, the Traveler in the sky seemed to suddenly turn into a divine sword that could break through all shackles in heaven and earth!
Even from a distant distance, Venti could vaguely feel his face being pricked by the invisible but omnipresent sword glow.
If Venti felt this way, Stormterror, who was directly targeted by Bai Yu, was even more miserable.
Stormterror, who could easily fly far away with just a light flap of his dragon wings, felt like the air around him had suddenly become incredibly viscous.
No matter how hard it flapped its once powerful dragon wings, its body felt like a rat stuck on a glue trap. It could only struggle in vain and waste its energy, unable to do anything to free itself.
(Has the sword heart breaking through to the Mingjing realm, penetrating the self's back, achieved such an effect?)
Even Bai Yu himself was slightly surprised by this scene. In the Wuchen realm, he could easily lock onto his target with his mind and control the flying swords to attack at will, but he couldn't do what he was doing now. Relying on his sword heart to lock onto a target, he could make someone weaker than him stand there like they were petrified, unable to do anything but take a beating.
With a thought, Bai Yu was surrounded by a gentle breeze.
Lumine's body had only unlocked the power of the Anemo element. Although Bai Yu could do things that Lumine couldn't, it would be too complicated.
The wind was enough.
In an instant, under Paimon's astonished gaze, the "Traveler" became a swordsman from a myth, condensing twelve Anemo flying swords around him (her) in the blink of an eye.
"Use the heart as a sheath and nurture a sharp sword!"
The sword flew out.
The world changed color!
