For a whole afternoon, during the few hours that Zheng Xiuyan went to class, Zheng Xiujing had been sitting next to Li Junhyuk and listening to Li Junhyuk's various knowledge and tips about songs explained to him with relish.

In fact, the reason why the active Zheng Xiujing can listen so fascinated is because of Lee Jun-hyuk's rich knowledge. You must know that Lee Jun Hyuk has never been able to do without books, and even during this time, he was so busy on the spot in the crew, and he also found time to read three books on movies.

Therefore, in the explanation of every question and knowledge point, Lee Jun-hyuk can tell some very interesting stories to make Zheng Xiujing better understand. And Zheng Xiujing was also deeply attracted by Li Junhyuk's lecture style. It's like a different person, and I listened to Lee Jun-hyuk's explanation very carefully.

It wasn't until Zheng Xiuyan came back from class that Zheng Xiujing returned to her original appearance and ran downstairs to meet her sister.

"Ernie, you're back." On the stairs, Zheng Xiujing saw Zheng Xiuyan who was going upstairs and said excitedly.

"Well, Xiujing, how was your afternoon here, were you naughty?" Although Zheng Xiuyan is still a child, she is still very good at taking care of people when her parents are away.

"Of course not, Ernie, come and see the cookies I made, I just ate one, it's super delicious." During the afternoon break, Lee Jun Hyuk had already taken the baked cookies out of the oven. However, at that time, she needed to wait for the cookies to cool down, so although Zheng Xiujing looked greedy, she never ate them, and later she began to study with Lee Junhyuk. Didn't come out to care about these cookies again.

After hearing my sister open the door. When Zheng Xiujing ran out to greet her sister, she took two cookies from the pastry table. Ate one yourself. Then he handed the other one to his sister and said excitedly.

"Wow, this is so sweet, Xiujing, how much sugar did you put in it." Taking the cookie handed over by her sister, Zheng Xiuyan took a bite lightly, and then, the greasy sweetness spread in her mouth. So, Zheng Xiuyan asked with a frown.

"Sweet? No, the taste I just ate is just right, and it tastes super similar to what my uncle made. Hearing Zheng Xiuyan's words, Zheng Xiujing said strangely.

"Then try it, this one is really super sweet." Seeing her sister's innocent appearance, it didn't seem to be pretending, but the cookie in her hand was really too sweet, so Zheng Xiuyan handed the half-eaten cookie back to Zheng Xiujing and said.

"Wow. Why is this so sweet. Sure enough, Zheng Xiujing took her sister's cookie. She ate it in one bite, and then she immediately frowned and said.

"How so?" Swallowing the super sweet cookies into her stomach, Zheng Xiujing said strangely.

"Because I made a third of the cookies here, and although you made the shapes of these cookies by yourself, I took you to make them once when I made them, don't you forget?" Just when Zheng Xiujing was wondering, Li Junhyuk walked out of the house and said.

"Ah, by the way, uncle, you also made one, I said how could the food I just eat be so delicious." Hearing this, Zheng Xiujing suddenly realized.

"That's not right, I remember when I was making the cookie shape, I put the one made by my uncle and the one I made separately on the baking sheet, but when I took it just now, I also took it on a plate, it stands to reason, the taste of the two should be the same, why will one be normal and the other sweet." Immediately afterwards, Zheng Xiujing began to wonder again.

"I made that too, because the cookies need to be flipped while they're cooling, or they'll stick to the baking sheet." Lee Jun-hyuk explained again.

"I see, so in this way, among these well-made cookies, there is about a two-thirds chance that you will eat that kind of greasy cookie?" Hearing this, Zheng Xiuyan calmly analyzed.

"No, there should be only a one-in-three chance of eating this super sweet." Hearing Jung so-yeon's words, Lee Jun-hyuk said.

"What's the matter, isn't most of this place made by Xiujing?" Hearing Lee Jun-hyuk's words, Jung so-yeon asked puzzled.

"When I did it for the first time, I was always by my side, and every movement of Xiujing was also according to my demonstration, so it shouldn't be sweet for her to do it for the first time. As for these sweet cookies, it should be the result of the time when the two of us started practicing, Xiujing made it herself, I think, she wanted to make it sweeter, after all, the cookies in my store are still much lighter than the cookies in other places on the market, and Xiujing may want to put a little more sugar to make the sweetness of most cookies, but because she has no experience in making them, she will put more sugar, so that these cookies are so sweet. Lee Jun Hyuk guessed.

"Uncle is right, I just wanted to make it a little sweeter, and I didn't think there was much more sugar in it, how could it be so sweet." Hearing Lee Jun-hyuk's conjecture, Zheng Xiujing agreed.

"Because you're doing it for the first time, you have no experience, and it's okay to take it slowly." Seeing that Zheng Xiujing was still wondering, Li Junhyuk smiled and comforted.

"But, anyway, these cookies have been mixed into ordinary cookies, and now, every time you eat them, they are all 'blessed'. Alas, it's unpleasant to think about it. Zheng Xiuyan looked at the table full of cookies and said depressedly.

"Actually, it's not as bad as you think, because these cookies are in different positions in the oven, so they can still be distinguished by careful color differentiation, the top layer, usually the color will be darker, and the further down, the lighter the color." Seeing Jung so-yeon's depressed appearance, Lee Jun-hyuk said with a smile.

"Really, hehe, it's good now." According to Lee Jun-hyuk's words, Jung so-yeon tried it and found that as Lee Jun-hyuk said, all the darkest cookies were super sweet.

"Fortunately, there is also this method of yours, uncle, otherwise, Ernie would not dare to eat this." Seeing her sister's appearance, Zheng Xiujing breathed a sigh of relief. Said.

"Xiujing, you won't be making this cookie all afternoon, right?" The cookie matter was settled, and Jung so-yeon asked again.

"Of course not. I learned a lot about music with my uncle, especially singing, and I understand a lot of things now. Hearing her sister's question, Zheng Xiujing said in a coquettish voice.

"Yes. Tell me, what have you learned? Hearing Zheng Xiujing's words, Zheng Xiuyan continued to ask.

"It's those tunes that Ernie and Uncle practiced in the morning, and Uncle explained to me in detail all kinds of analysis and singing methods of these tunes in the afternoon, so I understand a lot about singing now." Hearing Zheng Xiuyan's question, Zheng Xiujing replied excitedly.

"How much do you remember?" Seeing Zheng Xiujing's cute appearance, Zheng Xiuyan couldn't help but touch her sister's head like Lee Jun-hyuk and continued to ask.

"Well, I've memorized a lot, especially a lot of tips on pronunciation and breath when singing, Uncle he told me, after an afternoon of practice, I now feel that I sing much better than before. If you don't believe me, I'll sing you one. Uncle, can you please help me accompaniment? Speaking of this, Zheng Xiujing was already completely excited.

"No problem, let's go to the stage on the first floor, there is a piano there, and a back-bought harmonic device, the sound source is much better than the one upstairs, let's do a super small concert for Xiujing." How about it, Xiujing, will you be nervous. Hearing Zheng Xiujing's request, Li Junhyuk agreed with a smile.

"I won't be nervous, I'll definitely surprise my sister after a while." Hearing Li Junhyuk's words, Zheng Xiujing said arrogantly.

Indeed, after an afternoon of explanation and practice by Li Junhyuk, Zheng Xiujing's singing skills have improved a lot, of course, this is also because she has not systematically studied vocal music, so she seems to have made such great progress.

"Well, Ernie, I've improved a lot." After singing two songs, Zheng Xiujing jumped into Zheng Xiuyan's arms, looking like "praise me".

"Of course, our Xiujing is so smart and cute, is it normal for us to have made such great progress." Zheng Xiuyan said with a smile when she saw her sister's appearance.

"Yes, sister, where am I cute?" Hearing Zheng Xiuyan's words, Zheng Xiujing was extremely satisfied. But then, she asked.

"Well, it's so cute from head to toe. Okay. Seeing Xiujing's unrelenting questioning, Zheng Xiuyan continued to praise.

Lee Jun-hyuk sat in front of the piano and watched the interaction between the two sisters with a smile, which was very interesting, and when he saw Xiao Xiujing's questioning, he saw Zheng Xiuyan doting and saying, "It's so cute from head to toe".

Suddenly, a flash of inspiration flashed in Lee Jun-hyuk's mind. (To be continued......)
