A trace of disappointment crossed Rose's face when she heard Lin Guang's words.
Seeing her disappointment, Lin Guang forcibly suppressed the stirrings in his heart and said, "You're still a demon. Although you've escaped Muzan Kibutsuji's curse, you still need to consume blood, don't you?"
Rose nodded. "Master, you're right. But since you won't allow me to hurt humans, I can drink the blood of wild beasts instead. It won't be a problem."
Lin Guang smiled in satisfaction, then said, "Come here."
Rose walked up to him and looked up at his face. "What is it, Master?"
Lin Guang's hair gradually turned white, and his eyes became ice blue. Then he cut his finger and said softly, "Open your mouth."
Seeing what he was doing, Rose asked in surprise, "Master, what are you doing?"
Lin Guang said impatiently, "Why all the questions? Hurry up."
Rose looked at the blood on his finger. Although she instinctively craved it, she still had questions.
"Master, are you going to give me your blood?"
Lin Guang nodded, then said, "I fed my blood to a little girl before, and she ended up gaining the same ability as me. I want to see whether my blood was the reason."
Rose was astonished once again by his words.
"Master, is that true?"
Lin Guang gave a dismissive smile. "Do I have any reason to lie to you? Besides, if you don't hurry up, my wound will heal."
As he spoke, he urged Rose to get on with it.
"Then please excuse me, Master."
Rose first lowered her head in apology, then cradled Lin Guang's hand in both of hers and took his bleeding finger into her mouth.
Lin Guang hadn't expected her to do it so directly, and he couldn't help thinking to himself.
It's warm. Feels pretty nice, too.
Then Lin Guang felt his blood being drawn out little by little. When he reckoned she had taken about a hundred or two hundred milliliters, he said, "All right, that's enough."
Hearing his words, Rose reluctantly opened her mouth, giving his finger one last lick before releasing it.
"Your blood is so cool when you're like this, Master. It has a faint fragrance, too. It tastes wonderful."
Lin Guang gave her a hard rap on the head.
"Who asked you about that?"
Rose held her head and said miserably, "I don't feel anything else."
Hearing that answer, Lin Guang rubbed his chin in puzzlement.
Was my guess wrong? But that shouldn't be possible! There must be something I'm missing!
Then Lin Guang glanced at Rose and said, "All right, it's getting late. Dawn should be coming soon. I have one last task for you."
At the mention of a task, Rose sat upright in front of him.
"Please tell me what it is, Master."
Lin Guang said slowly, "From now on, kill any demon you see hurting people. If you run into members of the Demon Slayer Corps, help them if you can. But if you encounter any powerful members, there's just one thing to do: run. Understood?"
Rose nodded. "Understood."
Lin Guang turned and walked to the door of the dilapidated hut, and Rose instantly retracted all her threads.
"Remember, your life belongs to me. Neither another demon nor another human is allowed to take it."
Lin Guang glanced back and left her with those words before walking out of the hut.
Rose stood motionless inside the hut, watching his retreating figure with a beautiful smile.
Suddenly, Rose felt the blood in her body gradually growing colder, and a hint of drowsiness came over her.
Just what I'd expect from Master's blood. I've only absorbed a little, and my body already feels cold. It also seems to be eating away at my body.
Clutching her lower abdomen, Rose staggered out of the hut. When she saw a faint glow along the horizon, she knew dawn was approaching.
She rushed into the mountain forest and found a cave, then sealed its entrance completely with spider silk and rocks. By then, a layer of frost had already formed on her face.
Once she had finished, Rose lay down on the ground and fell into a deep sleep.
Meanwhile, apart from a slight chill in the spider mark on his arm, Lin Guang felt nothing unusual.
He passed through the small village, crossed a vast stretch of woods, and climbed over a mountain before returning to the Butterfly Mansion.
Entering the Butterfly Mansion's courtyard, Lin Guang activated Mind Perception and quickly located Shinobu Kocho.
When he arrived at the medical room, he saw Shinobu Kocho looking through her notes before picking up a cup of water infused with wisteria.
Lin Guang snatched the cup from her and poured it out. "You should stop drinking this from now on."
Shinobu Kocho looked at him with a faint smile.
"Lin Guang, you're back. It looks like this mission was an easy one."
Lin Guang said, "With me here, you don't need to keep taking this stuff. Trust me, all right?"
Shinobu Kocho grew calm, then looked into his eyes and said slowly, "I know you want to help me. You even developed Ice Breathing. But I still want to take revenge myself."
Lin Guang smiled softly. "All right, then. Since you're good at developing medicines, I happen to have something useful for you."
With that, Lin Guang slipped his hand into his pocket and took four bottles of potions out of his Spatial Ring, pretending to pull them from his pocket before setting them in front of Shinobu Kocho.
"I came across these four potions by chance. All four can enhance the body's functions. Study their ingredients and see if you can reproduce them."
Shinobu Kocho picked up one of the bottles and looked at him. "Have you tried all of these yourself?"
Lin Guang nodded. "Of course."
Then Lin Guang explained to her what each one did.
Shinobu Kocho's mouth fell open in astonishment.
Seeing her surprise, Lin Guang said, "If you don't believe me, you can try a bottle first."
Shinobu Kocho immediately opened one of the bottles and drank it.
As time passed, Shinobu Kocho felt her body fill with strength, indicating that the potion she had just drunk was the strength-enhancing one.
She immediately challenged Lin Guang to an arm-wrestling match. Although she still lost, she could genuinely feel that her strength had increased.
"Amazing! My strength nearly doubled. If Mr. Gyomei used it, the effect would probably be even more obvious."
Hearing Shinobu Kocho's words, Lin Guang felt rather pleased with himself.
Of course. Anything the system produces is top quality!
Shinobu Kocho couldn't resist drinking the other potions as well. After testing their effects, she found that her stamina and speed had improved dramatically, and even her mind worked faster.
After discovering these results, Shinobu Kocho looked at Lin Guang with sparkling eyes. "Lin Guang, do you have any more of these potions?"
Lin Guang smiled faintly, then took out another four bottles, again one of each kind.
"These are the last four. If you ask for more, there won't be any left."
