"So I picked it up?!"

Yang listened to the bickering between the brother and sister, shook her head helplessly and went to take care of her own things. As for Su Xuanhe, although he cursed with his mouth, his body was still very honest. He did whatever Su Qingluan asked him to do. Even if he retorted a few words, he did things without any delay.

At this time, Su Xueyan, who was looking for a playmate, ran to the kitchen and asked, "Brother, you are here? Come and play with me!"

"I don't have time to accompany you. Can't you see that I'm working as a temporary laborer for my sister?" Su Xuanhe said unhappily.

Su Xueyan said to Su Xuanhe seriously, "Sister must be feeling unwell, that's why she asked you for help!"

"Is she that considerate?"

"What is 'considerate'? Isn't it because you dislike my brother's clumsiness?" Su Xueyan has always been very good at complaining, especially when the target of her complaints is Su Xuanhe, then her words will be particularly sharp.

Su Qingluan was trying so hard to hold back her laughter that her intestines were about to get tangled, but she still said seriously, "Just help me move these two cleaned stones to the stove."

"Why are there stones here?" Su Xuanhe asked in confusion.

"I know, it's just like using stones to press down on pickled cabbage!" said Su Xueyan.

"It's a pity that Xueyan guessed wrong!" Su Qingluan smiled and pinched her sister's smooth little face. "The stones in the sauerkraut jar are to squeeze out the moisture in the cabbage, so that it can absorb more salt and keep the sauerkraut for a long time!"

As for the reason why it can be preserved for a long time, it is because it isolates oxygen and reduces oxidation reactions. There is no need to tell my sister. This is too beyond the scope for people of this era.

"Then why does sister want to use this stone?" Su Xueyan asked with a chubby face.
