My sister is Luna

"Are you really not bothered at all?" Shangguan Wan'er asked suddenly as she wrote.

Seeing Cain's relaxed demeanor, completely unaware of his severe poisoning and not taking it to heart, Shangguan Wan'er felt a surge of anger. It was a shame that she had been so worried about him not long ago.

"What do you care about?"

"Your strength is hard to improve. In the end, this world is still a world where the strong are respected. All the rules of society today were set by them. You have lost the qualification to enter the ranks of their kind. You can only live under the rules set by them. Why do you still act like nothing has happened? Is this the peaceful and ordinary life you want?"

"Do you want me to look that sad? To be honest, of course I do care, but I won't let it get me down. What's the point? I think that's very weak. Besides, there's more than just martial arts as a cultivation system in this world. There are also mechanisms and demonic paths, all of which can be used as power. Moreover, this world is so big. Can you say that we humans have explored it all? What we've seen is probably just the tip of the iceberg. There are other mysteries that exist. Once you think about it carefully, you'll suddenly realize that there's nothing to care about. If one path is blocked, there are other paths. I have no reason to stubbornly persist on this one path."

Cain rested his chin on his hand and smiled as he looked at Shangguan Wan'er.

"No wonder Dr. Sun said you have a strong mental fortitude and there's nothing to worry about. You have a broad perspective and must have seen many sights, much better than me, who has never left Chang'an. I'm sorry, I was narrow-minded and said some unnecessary things."

Shangguan Wan'er paused for a moment, then said with relief. The pen in her hand stopped writing; these words had given her some insight.

“It’s alright, you’re just concerned about me. If you’d like, I can tell you about the scenery I’ve seen along the way,” Cain said with a smile.

“Great! I’m very interested to know what the outside world is like as you describe it.” Shangguan Wan’er smiled broadly.

“Wait, I feel this is a bit unfair. I told you stories about the outside world, and you broadened your horizons, but I didn’t get anything in return. This is too unfair. You have to exchange something with me.” Cain suddenly moved closer to Shangguan Wan’er, his tone playful.

"What...what do you want?" Shangguan Wan'er panicked when she looked into those deep eyes so close to her.

"Then, use your body!" Cain said shockingly, sizing up Shangguan Wan'er.

"What?!" Shangguan Wan'er was stunned. A blush instantly crept up her cheeks. She was at a loss for words and was about to say something when Cain interrupted her.

"I want to write beautifully, so I'll use your body to teach me how to write, hand in hand, how about that?" Cain said earnestly.

"Oh, is that so?" Shangguan Wan'er breathed a sigh of relief, looking somewhat embarrassed.

"Yes, what did you think it was?" Cain looked at her with an innocent expression.

"No, no, it's nothing. I'll teach you to write. Is that fair?" Shangguan Wan'er said, blushing as she brushed it off.

"Oh." Cain nodded with a pleasant smile, making Shangguan Wan'er feel that he had done it on purpose.

"Oh, right, when I turn back into a girl, you can call me Wan'er." She suddenly remembered something and said rather formally.

"Ah? Wan'er?"

This time it was Cain's turn to be stunned. He had never thought of calling her "Wan'er" in such an intimate way. After all, Cain had only known her for a few days and they weren't comrades-in-arms, even though she had known him for more than half a year and had taken care of him.

"I'm so handsome, could it be that someone has feelings for me?" Cain's mind wandered.

"Pfft, don't misunderstand. I've already considered you a friend, that's why I let you call me that. Don't you want to?"

Looking at Cain's expression, Shangguan Wan'er couldn't help but laugh, while feeling a sense of exhilaration at having won the contest.

"How could that be, Wan'er?" Cain understood, and thus respectfully complied.

"Mmm!" Shangguan Wan'er responded, her face slightly flushed, as if she hadn't gotten used to being addressed like that yet.

What's going on? I only wanted to treat him as a true friend...

The sunset illuminated the sky and the two of them, and the setting sun witnessed the birth of this "friendship".

……

"Yuan Fang, how do you see?"

Under the candlelight, Di Renjie flipped through the cases and information in his hands, and without looking up, spoke to the short, half-demon boy beside him.

“Kain came from the West and ended up at the Great Wall for unknown reasons. He became a member of the Great Wall Guard and defended the Great Wall when the Dark Tyrant attacked. He defeated the tyrant and was then taken to Chang'an by Cheng Yaojin for treatment due to his serious injuries. After waking up, he was highly regarded by Her Majesty the Empress, but he refused to serve as an official. That’s all we know for now. We still have too little information about him,” Li Yuanfang replied calmly.

“That’s right. We know nothing about his past experiences, what he did in the West to come to the Great Wall, what his purpose was, what kind of person he was, etc. We don’t know any of these things. He’s an unstable person.”

“I don’t think there’s anything suspicious about him, Lord Di. His behavior is nothing like that of a Westerner, and he’s not ostentatious at all,” Li Yuanfang pondered.

"Isn't it suspicious to be a Westerner who doesn't look like a Westerner, or a Westerner who looks like an Easterner?"

"Then, Lord Di, should we arrest him and interrogate him? Or perhaps we could set him up as a sting operation?" Li Yuanfang's fluffy ears twitched occasionally, making him quite adorable.

"No, before there is evidence, he is only a suspect. We can't let the bad guys go free, nor can we wrong the good guys. So we need to collect evidence, decisive evidence, so that we can judge him, keep an eye on him, and see if we can find any clues."

Di Renjie closed the case in his hand, his sharp gaze fixed on the distance, and said:

"Moreover, if we can confirm that he is a stabilizing factor, we might try to recruit him to join our work. His strength is a good fit for our work, and it will also help us to carry out our work smoothly when we encounter some troublemakers in the future."

"Yes."

As Li Yuanfang was about to disappear into the darkness and begin his operation, Di Renjie said again:

"There's one more thing, please bring me a late-night snack when you come back."

"Lord Di, could you be a little gentler on my salary assessment next month?"

……

"~~~~~" The melodious and pleasant sound of the zither echoed continuously in the small courtyard filled with brightly colored peonies.

"Sister Yuhuan's zither playing is always so beautiful; it always makes me feel happy," said the lively bunny-eared girl.

"Some interesting things will happen in the next few days, Tiger, you'd better be careful." The handsome man in white, Fang Tu, fiddled with the peony, a meaningful smile on his face.

"Ah, I see. By the way, what's with that gloating look on your face?" the thin young man said lazily, leaning against the tree.
