Sun Lingtong's heart was pounding and cold sweat broke out on her forehead.

He licked his dry lips and continued his performance: "Is that the secret formula? Of course I know it, don't worry."

"But the question is, which formula do you want?"

Butterfly Girl looked stunned: "What do you mean? I only have one secret formula."

Sun Lingtong shrugged, spread his hands and said: "For you, of course, there is only one secret formula."

"But we're not."

"We know too many secret formulas. After all, we are inspectors. When encountering a situation like yours, we have to use secret formulas."

"It's precisely because we know too much that we kind of forgot which secret formula you need."

Butterfly Girl was stunned.

Sun Lingtong continued: "So you can tell me some of the contents of the secret formula. I need some reminders."

Yang Chanyu: "..."

Butterfly Girl's expression changed, and she said thoughtfully: "What you said does make sense."

"Then I'll tell you."

"The content of the secret formula is, Yun'erfei, Yun'erfei... wait, wait a minute!"

"If I directly tell you the content of these formulas, doesn't this mean that I'm directly leaking the formulas to you?"

She finally reacted, staring at Sun Lingtong angrily with her eyes widened.

The momentum in her body continued to rise, and she was about to take action.

Sun Lingtong waved her hands quickly: "Wait a minute, don't rush to do it! I just asked you to remind me, and I didn't say directly tell me the content of the secret formula."

Butterfly Girl interrupted: "But you just understood."

Sun Lingtong also interrupted her: "What I just said may not be clear, and you may have misunderstood it."

"But that doesn't matter, does it?"

"Look, I'm a child and I can't speak clearly. Isn't that normal?"

"You just need to give me some tips, okay?"

"I didn't ask you to tell me the entire secret formula."

Rudie Niang tilted her head, stared at Sun Lingtong, and kept looking up and down.

Sun Lingtong stared at her with big watery eyes, looking at her with innocence.

She was touched again and thought that such a child could not be treacherous.

But after thinking for a long time, she said: "Well, I still doubt you a little, but I am willing to give you one last chance."

"My hint to you is that the secret formula is a nursery rhyme."

Sun Lingtong groaned: "Nursery rhymes..."

"Sure enough, it still doesn't work. Don't waste any more time. Sun Lingtong, come with me to do it!" Yang Chanyu secretly transmitted the message.

Sun Lingtong's eyes suddenly lit up and he waved his hand to Yang Chanyu.

"I thought of it."

"Thank you for reminding me. I know what your secret formula is?"

"Just listen to me singing."

The next moment, Sun Lingtong cleared her throat and started singing in a low voice.

The clouds are flying, the clouds are flying,

Flying over mountains, rivers and green hills.

The gurgling stream winds around the big trees,

The sun shines on the green grass.

…

The clouds fly, the wind chases,

Flying over rivers and stars.

The sky and the high ground are far more beautiful,

The clouds roll and relax, letting the wind blow.

…

The clouds are flying, my heart is tired,

Flying over rainbows and clouds.

The glow in the sky gradually fades,

The shadow of the moon quietly reflected the dark sky.

…

Clouds fly, dreams return,

Flying over the thoughts and sorrows.

Mother takes you home in her dream,

Go back to your hometown and sleep peacefully.

…

Rudie Niang's expression softened and she bowed deeply to Sun Lingtong: "I wrongly blamed you. Please take me out."

"Easy to say, easy to say." Sun Lingtong said with a smile.

The next moment, Butterfly Girl closed her eyes and really went to sleep.

Sun Lingtong decisively stuffed it into the storage bracelet.

Now, Yang Chanyu was completely impressed by him!

Before this trip, she thought she would be the main force. Unexpectedly, along the way, Sun Lingtong's performance repeatedly exceeded her expectations.

Yang Chanyu was full of doubts and asked directly: "How do you know this nursery rhyme?"

Sun Lingtong chuckled: "This is the most widely circulated nursery rhyme in Feiyun Kingdom, and it is often used as a lullaby for mothers to coax their children to sleep."

Yang Chanyu asked: "How did you know?"

"Reading thousands of books means traveling thousands of miles. There is a lot of knowledge that cannot be obtained by just reading." Sun Lingtong chuckled, but his eyes were dazed for a moment.

…

Two or three-year-old Ning Zhuo huddled in bed, sobbing.

Sun Lingtong came to the bedside and asked curiously, why are you crying? Why are you still not sleeping?

Xiao Ningzhuo poked his head out from under the quilt: "I, I miss my mother."

Sun Lingtong felt like she had a big head. She wanted to say something to comfort her, but she stuttered and couldn't say it well.

The more Xiao Ning Zhuo talked, the sadder she became, and tears flowed down her face: "I, I can't sleep. Whenever I can't sleep, my mother will sing to me. Can you sing for me?"

Sun Lingtong opened her mouth and thought: "How could I, a noble cultivator from the evil sect, do this... eh?"

He retreated under Xiao Ning's helpless and eager eyes.

"Okay, okay. What song do you want me to sing? I don't know how to..."

"It's okay, I can teach you. Yun'erfei, Yun'erfei..."

Sun Lingtong sighed deeply: "Okay, I will only sing it once. You have to go to bed quickly, do you understand?"

Xiao Ning huddled in bed and nodded weakly.

Sun Lingtong sat on the edge of the bed, her calves naturally hanging down, turning slightly sideways, suppressing a sense of shame, and sang in a low voice: "Yun'erfei, Yunerfei..."

"The sun shines on the green grass..."

Xiao Ningzhuo suddenly interrupted: "You sang it wrong, it's a haystack, not a haystack."

"Oh, oh. I'll sing it again... What's the beginning of it?"

After many pauses and corrections, I finally finished the song stumblingly.

Sun Lingtong was covered in sweat.

"Why aren't you sleeping yet?" He looked at Xiao Ningzhuo's bright eyes and felt bad.

Xiao Ningzhuo frowned, very distressed: "My mother is not like this when she sings. She is very smooth, her voice is very light and gentle. If you sing like this, I can't even sleep."

Sun Lingtong: "Then I will sing it again."
