After walking around outside all day and night, when Xu Jing went home once, Xu Lao stared at him for a minute, and then hesitated: "Where have you been?

Xu Jing subconsciously looked at the sky outside, and then replied: "When I came back from Jingtian, I specially picked a very early time, and now when I get home, it is not dark outside." The sun hasn't come out today, but it's clear that it's not the time for the sun to set. ”

Xu Lao shook his head: "I didn't say it was dark, I meant that you were getting dark." ”

Xu Jing looked at his hand very suspiciously, and did not feel that he had a tendency to turn black, and silently prepared to find a mirror in the room to take a look.

Then I found that the house was full of rough old men, and there was no mirror in the house that was easy to find, so I still rummaged through the cabinet for a long time before I picked up a broken mirror piece from the bottom of the cabinet.

It is estimated to be the wreckage left behind by the last broken mirror in the house.

When he first heard Xu Lao say this, Xu Jing didn't care.

In this big winter, he ran outside, where can he tan.

And he didn't stay in the kitchen, he lit the fire every day, and it was impossible for him to blacken himself.

Xu Jing subconsciously felt that Xu Lao's assertion was actually because Xu Lao's memory was wrong, thinking that Xu Jing was relatively white before.

However, after Xu Jing took the mirror over and took a closer look, he found that he was indeed a lot darker, and when he smiled, he showed a mouth full of white teeth, which was very eye-catching.

Xu Jing was stunned: "...... What's going on?"

Xu Jing confirmed that he was not basking in the sun and did not smoke himself bacon.

But I just don't know why I'm hacked like this.

Xu Lao was also very confused, walked over and touched his grandson's face carefully, and found that there was no messy thing on his face to coax him to play, but it was really dark.

It's good now, the starling who brought over has lost weight, and the grandson who chased after him has gone black.

I know that they traveled a year ago, and I don't know that I thought that he took these two out for military training.

And it's the kind he personally did as an instructor.

Xiao Zhang also came back early at this time, sitting in the hall drinking tea, and after hearing their words, he also glanced at Xu Jing, and found that he was indeed a lot darker.

But there's nothing surprising about that, Zhang explained.

"It's not the heat in the sun that tans people, it's the ultraviolet rays in the sun. So in the winter, although you don't see the sun too much every day, there are actually ultraviolet rays in the air. Xu Jingtian runs outside every day, bathed in ultraviolet rays, and naturally tans. ”

Xu Jing was strange: "But I haven't heard of any winter when you go out and can get a tan, so I'm also setting a precedent." ”

Xiao Zhang smiled: "In fact, in winter, there are generally more cloudy days, the clouds in the sky are thicker, and the weakening effect on ultraviolet rays is also stronger, so generally in winter, there are fewer ultraviolet rays, so the tanning effect on the skin is relatively less." ”

"If the average person is outside in winter, he will not tan so obviously as you do, but it can only be said that during this time, you spend too long outside, even if the ultraviolet rays are weakened, you will still tan. ”

Xu Jing just thought about the itinerary of these days, and found that he did run outside every day with dogs and birds, so it was no wonder that he looked like this.

After Xiao Zhang opened his mouth, he simply continued to talk for a while.

"When it comes to tanning, many people think that they only get tanned when they are standing in the sun, but in fact this is one-sided. Because ultraviolet rays sometimes have a refractive effect, even on a sunny day, you will be tanned by the refracted ultraviolet rays on the ground and other objects. ”

"And it's not just during the day, at night, because of the effect of the atmosphere, there is still a small amount of ultraviolet rays in the air at night, so it can also tan people at night. ”

"Those who don't have are fake, if you really want to raise yourself as Snow White, just nest in the house and don't come out. ”

Xu Jing had nothing to say, and felt that his three views had been forcibly refreshed again.

In the past, he only knew that standing under the sun would tan, but if he dared to love now, not only could he stand in the shade, but even if he went out at night, he would be tanned.

Xu Lao shook his head and sighed: "According to what you think, those little girls are really not easy, in order to make themselves white, they have to stay in the house every day for a long time." ”

Xiao Zhang thought it was funny again, and continued to explain to Xu Lao: "That's not necessarily, there are many ways for their girls to become white." When you go out, you have to wear an umbrella, and even if you don't, you have to wear sunscreen. After coming back, there is a series of whitening skin care or something, which will naturally become whiter. ”

Xu Lao's attention was not on playing an umbrella and wearing sunscreen, the first thing he noticed was what kind of whitening skin care.

This time, I indirectly brought my eldest grandson here, but I brought it back in black and black, and I didn't think it was good.

Although the boys' families are darker, they still look healthier.

But when he went home and showed his grandmother, he felt that he had tormented her eldest grandson, and when the time came, he didn't like to listen to it.

Xu Lao hesitated for a second: "That...... Xiao Zhang, do you know how to whiten?"

Xiao Zhang: ?

Xu Jing: !

It can be said that he is worthy of being an ancestor and grandson, Xu Jing suddenly guessed Xu Lao's thoughts, and suddenly Xu Jing was not very happy.

Although I don't know what the legendary whitening methods are, what they are.

But the thought of smearing or something on his face made him feel crooked.

With this time, it is better to go outside to play for a while, he remembers that under the cliff on that side, there is still a place to see, and the crow also wants to go!

Speaking of crows......

"Grandpa, don't think about whitening me or something, I'm happy to be so dark, look at the crow, it's so dark, I don't like it very much. Since Wanguan likes black, then I must be willing to be a little darker myself. ”

Zhou Jiu was made a shield for no reason, and he really wanted to stretch out his golden claws in front of Xu Jing's eyes, so that he could see clearly that his whole body was not completely black.

And golden!

How rich!

How joyful!

It's just blind.

Xu Lao has nothing to say this time, since he likes his granddaughter-in-law, what else does he have to say.

When his wife asks, he can also reply with this reason.
