Here is the translation of your text into English. I have maintained the light-novel style and tone.
Before the start of the original plot, on Bo Wu Lan's birthday, Sarra Jergal will die. A few days ago, I thought about how to defeat Di Shan. I figured that more hands would mean more chances. Sarra Jergal is the child of the head of the "Black Hound," so they can at least use magic. And Otto Jergal, the head of the family, won't turn into a scumbag.
"Why are you lying around?" Bayan asked. "Resting," I said. "Rest time is over, get up," said Bayan. "Now we need to train your concentration. Can you use two spells at once?" As she spoke, I stood up from the grass. "Yes." "Really?" She looked at me skeptically, raising an eyebrow. "And how do you do it?" "Yeah, I just memorize my thoughts first. For example: 'I want to drink,' 'Deed Video is a bad service,' 'The Red Prince is a good novel.' Then I loop those thoughts in my head simultaneously while also reciting the spell." "That sounds difficult..." Mid-sentence, Bayan's face changed to something between surprise and disbelief. "Then show me."
I split my consciousness in two and began to whisper: "Phantom-woven hand, I call upon thee, fulfill my will." Two purple hands burst forth from my back. "God, that's such an outdated method. They used that eleven centuries ago. Let me teach you a new way," Bayan said. "Go ahead," I replied. "You need to use connecting words. For example, say: 'Phantom-woven hand, I call upon thee, fulfill my will, and I command thee further!'" Two magical hands emerged from her back. But they were blue, and unlike my water-like ones, they looked as if they were made of grass—blue threads. "Fine, I'll use connecting words," I said. "You can sit down," said Bayan. First she tells me to stand, then she tells me to sit? I sat in the lotus position. "Now, open both your palms," Bayan commanded. She placed fire in my hands. I realized I had to maintain both flames while she distracted me. "You need to keep the flames going while wearing this chain," Bayan said.
Chain of the Imprisoned Rose:
-2 to Kir usage.
You will be slapped in the face with a fish at random intervals.
She lay down on the grass, resting her head on her hand. A few minutes passed; the fish hit me several times, but I managed to keep the flames alive. My cheek was badly swollen. A question popped into my head. "Why does my magic hand look like water and why is it purple? Yours isn't," I asked. "There are many theories about the diversity of auras," Bayan said. "Which is the most popular or the most scientific?" "Most explain it by saying people have different personalities. But people change over time, yet the aura doesn't. At least, no one has ever seen that happen." That was likely true; in the game, Sven's aura was gold and had a steam-like texture, just like Arthur's father. "Is that the correct theory?" "You decide. But it's the most popular. The version I believe in says that color and shape don't depend on anything. You're born, and your aura already has its color, texture, and shape. But don't worry, they'll teach you how to change it at the university using metamagic anyway."
A fish appeared out of thin air and struck my already swollen cheek. The flame in my left hand vanished. "You didn't do too bad," Bayan said with a smirk. I used "Awakened Mind" and imagined a loud, soul-piercing scream. AAAAAAAaaaaaaaAAAA "Aaah!" She jumped in fright, covering her head with her hands. Realizing it was my spell, she grew angry. She said through gritted teeth, "Why, you little..." Several fish appeared in the air in front of her and flew at me, hitting me multiple times. "Hahaha, did I scare you that much?" I said. But then I saw her eyes staring into nothingness; she was breathing heavily, trembling, and were those tears in the corners of her eyes? "Are you okay?" I asked. I walked over and shook her with one hand. Al Bayan suddenly bolted to her feet. A small blue tornado swirled around her, and she flew away, leaving a blue trail of aura behind her. "I'm sorry!" I shouted after her, but it was too late; she had flown too far.
God, oh God, what have I done? I thought. I brushed the dirt off my pants and shirt. This was only our third lesson, and she had already run off. What am I supposed to tell my parents?
I sat on the back porch for another half hour, practicing in the spiritual world a few times. I began to see even the smallest particles within a meter of me; anything further away appeared only as large white particles. Still, without an artifact, I couldn't truly see the spiritual world.
[The spiritual world is the world beyond our eyes; it is a more complex, real world. My artist friend used to say that to draw, he breaks things down into simple shapes. Likewise, the ordinary eye sees a simplified form. Every color is a wave; even that wave is a mathematical formula.] I remembered these lines from Ryu Manju's book. He wrote that he first saw the spiritual world while on mushrooms that work like Modafinil but are ten times stronger. Hehehehe, I'll buy some at the shop and use them now.
