Cen Yun was so angry that she reflexively snorted.

Cen Jia didn't care and walked out with the box.

Come to the park gate.

Cen Yun said proudly: "Jiajia, you are so good, you actually met with a fixed color, I really underestimated you in the past, but I didn't expect you to be a good hand at making pastries, and in the future, our steamed bun shop will not worry about no one inheriting it." ”

Qiao Qiao bit the bun, and her smiling face was full of worship: "Sister Jiajia was so amazing just now!" ”

Cen Rong looked at Cen Jia with a dark color: "What can you do to make steamed buns, Jiajia, you have this time, let's use it more to study." ”

Cen Jia nodded, although the aunt said this for her good, she was not very comfortable in her heart.

"How about you two go back?" Cen Rong then asked: "I won't go to work today, I'll take Qiaoqiao to my mother later." ”

Cen Yun yawned and said, "Well, I'll go back, just in time for a good night's sleep." ”

Cen Jia shook his head: "I'm going to call my mother, or sister-in-law you and aunt go back, I'm walking to the street, and there is not much way." ”

It is only a ten-minute walk from the optical factory to the city center.

Cen Jia tied the foam box to the back seat, Cen Yun stepped on the bicycle, looked at Cen Jia's waist bag and said, "I'll bring you the money back, it's not safe for you to bring so much money with a little girl." ”

Cen Rong frowned: "I'll keep it for you." ”

Cen Jia's pocket not only has 56 yuan from today's business, but also more than 20 yuan from taking out change, a total of more than 80 yuan.

Of course, it is much more reassuring to hand it over to Cen Rong than to Cen Yun, and Cen Jia only left five yuan.

Cen Rong is not happy to see it, how many years has her brother and sister-in-law been divorced, and this dead girl can't forget her water-based Yang Hua's mother, who used so much money to make long-distance calls to her.

"You go home early after the call, don't go crazy outside." Cen Rong explained, rode a bicycle, and went back to her parents' house with Cen Yun.

Cen Jia stood in place, speechless at the attitude of the aunt, is she so disgusted with her?! No wonder her personality was so cowardly when she was a child, it is strange that she has such an aunt who blows from time to time, and her personality can be confident.

Cen Jia was about to leave, but someone stopped her.

"Little girl, don't be busy walking, I have some questions for you."

Cen Jia turned around, and it turned out to be the old man who had bought her ten buns in one go just now.

"Hello, grandpa."

The old man had been waiting for Cen Jia to be busy before he stepped forward to talk, and a smile tugged at the corner of his mouth: "Do you know what the principle is for your solid color formula?" ”

Cen Jia glanced at the old man up and down, and a thought popped up in his heart, this old man looked like he was knowledgeable, could it be that he was a master and was testing himself with this question?

In fact, this problem is also simple, it is nothing more than some simple chemical reactions.

However, no matter how simple it is, it is not something that Cen Jia, a twelve-year-old girl, can learn.

What happens if the answer is answered?

Cen Jia smiled politely: "Grandpa, spinach is rich in chlorophyll, adding baking soda can prevent the loss of chlorophyll, so that the spinach juice can naturally keep the spinach juice green, and purple potato beetroot is different, beetroot is rich in anthocyanins, turning blue when alkalin, and red when acid, so adding vinegar can keep the bright red." ”

The old man stroked his palms with satisfaction: "Well said, it is indeed such a principle, there is no dead study, you can use the knowledge you have learned in daily life, you little girl is really good!" ”

Cen Jia modestly politely said a few words, thinking that the old man would give her something, but the old man just asked Cen Jia if he would come to set up a stall tomorrow.

After receiving Cen Jia's affirmative answer, the old man left with the bun.
