She subconsciously walked towards him with short legs, her cheeks upturned with surprise, and her eyes full of inquiry.

Ning Zhi guessed with his head: "Are you rinsing your mouth?" ”

Song Shenbai, who was brushing his teeth, lowered his head and met the little girl's curious black eyes.

Her ignorant and innocent appearance was like a little elk lost its way in the woods, which made him feel very soft somewhere in his heart.

He swallowed a little water, spit out the toothpaste foam between his lips, and nodded at her, "Yes, rinsing." ”

Ning Zhi's eyebrows were puzzled, pinching the corners of his clothes, and asking, "But why do you use a brush to rinse your mouth?" ”

She remembered that the people here all used willow branches to clear their teeth, or they would just drink some well water and then vomit, which was not much different from ancient times.

As for the brush, she really hadn't seen any of the villagers use this at home.

"It's called a toothbrush, and it's specifically designed to clean your teeth." Song Shenbai completely stopped brushing his teeth, leaned down to look at her, and patiently and gently explained: "If you add toothpaste, your teeth will be brushed very clean, which is better than willow branches." ”

"I see." Ning Zhi's face couldn't help but turn red after he understood, and he was secretly annoyed by his stupidity.

It's a pity that the dog prince is not here, otherwise he wouldn't know how to ridicule and laugh at her.

Song Shenbai lowered his eyebrows, looked at the washbasin she dropped on the ground, lowered his body to pick it up and asked, "I remember that I prepared a toothbrush for you, why didn't you use it?" ”

Ning Zhi's face turned even redder when he mentioned this, his fingers rubbed the hem of his clothes shyly, and the thin voice was almost inaudible: "I...... At first, I thought it was for me to brush my shoes......"

So when she came out to wash, she took it out and put it aside, thinking that she would use it again the next time she brushed her shoes.

Using a toothbrush as a shoe brush?

No matter how strong Song Shenbai's concentration is, he can't help but smile.

However, his smile was not half mocking, but his ink eyes were clear and pure: "It's okay, it's not too late to know its true usefulness now, why don't you try a toothbrush to brush your teeth?" ”

He raised the corners of his lips and proposed, a smile better than the light of the morning sun.

"Yes! Absolutely! "Ning Zhi, a little antique, naturally loves new things, so naturally he can't help but give it a try.

She retrieved the toothbrush from the room that had been set aside.

Song Shenbai squeezed some toothpaste for her, and intimately told her how to brush her teeth: "When brushing, brush up and down, lighter, don't touch the gums to avoid bleeding......"

The heads of the two children almost touched each other, and they looked fluffy in the gentle summer night, like little milk geese stuck together.

Ning Zhi listened carefully, for fear of missing something.

Then she brushed her teeth the way he had taught, carefully keeping the toothbrush close to the baby teeth.

When the toothbrush is in the mouth, the strong mint flavor of the toothpaste instantly occupies the entire mouth, refreshing and refreshing, like stuffing a piece of ice, clear and cool.

Ning Zhi opened his round eyes, and his surprised appearance was exchanged for a low laugh from Song Shenbai.

After brushing her teeth, Ning Zhi obviously felt that her teeth were several times cleaner, and her breath was fresh, like a mouthful of winter frost and mist.

This makes Ning Zhi proud, she is the first ancients to use a toothbrush!

Yikes!

If this was known by her group of ancient little sisters, they wouldn't know how much to envy her!

Song Shenbai stared at the little girl who was snickering at the toothbrush, her eyebrows were raised proudly, and her cheeks trembled excitedly, like the silly cat in the corner who stole a fish.
