Song Bo pushed Mu Xingzhi's wheelchair into the yard, clasped his fists and bowed, then stood outside the door. Originally, Yang and Su Guangfu invited him to come in and sit down, but he was told that etiquette must be abandoned and he could not sit at the same table with the host.

After all, Mu Xingzhi, the host, was there, and it was difficult for others to say anything, so they had to give up. Then Mu Xingzhi and Su Qingluan began one of the "fixed procedures" of returning home, which was to serve tea to their parents.

Although Mu Xingzhi was in a wheelchair, Su Qingluan was obliged to kneel and perform the full ceremony. Fortunately, these were her parents. Su Guangfu and Yang Shi were reluctant to let their daughter kneel on the cold ground in the autumn. They basically pulled her up as soon as her knees touched the ground.

As for Mu Xingzhi, whether he was serving tea or performing formalities, there was not a single flaw to be found, as if he had practiced this kind of etiquette thousands of times.

In fact, Yang and Su Guangfu still have more or less a "Mr. Mu filter" for Mu Xingzhi - even though he has become their daughter's husband and their son-in-law, it is still the same.

After all, it's difficult to change a person's habitual thinking in an instant. Su Guangfu and Yang, in particular, didn't have much opportunity to ponder such an abstract question as "habitual thinking."

Even Su Qingluan could see that when her parents faced Mu Xingzhi, even though Mu Xingzhi's attitude was very welcoming and the two of them were visibly becoming more relaxed from being uneasy, this "relaxation" was entirely due to Mu Xingzhi's deliberate guidance. They were both subconsciously still a little uncomfortable with being "respectful" to Mu Xingzhi.

This wasn't intentional, but rather a long-standing habit. Of course, Mu Xingzhi had the ability to gradually lower people's guard, but it took time and couldn't be accomplished overnight.

So when the pleasantries were almost over, Yang used the excuse that the kitchen was busy and was about to push Su Guangfu over to "deal with" Mu Xingzhi. Mu Xingzhi smiled and suggested: "If my father-in-law and mother-in-law are busy, you can trouble Brother Xuanhe to stay here."

Theoretically speaking, it is very rude for a newly-married woman to return to her parents' home after three days without the company of her host family. However, no one can say that it is "rude" to let a child under the age of eleven to be the "guest companion". After all, although Su Xuanhe is not yet an adult, he is still a member of the Su family.

Except for the little girl Su Xueyan who was only busy studying her brother-in-law's "wheelchair", everyone understood that this was Mu Xingzhi's way of giving Su Guangfu and Yang a way out so that they could leave smoothly.

As expected, knowing that they no longer needed to maintain such a tiring social scene, Su Guangfu and Yang did not feel at all that they were disliked by their new son-in-law. Instead, they said happily, "Then we will prepare some more food for you while you chat." Then they quickly went to the kitchen.

...Su Qingluan felt that the footsteps that had become noticeably lighter could be described as "escaping to heaven."

Seeing this, she couldn't help but smile gloatingly, raised her eyebrows and glanced at Mu Xingzhi beside her: Wow! It seems that you are not very popular!

Although he didn't know what Su Qingluan was thinking, Mu Xingzhi could clearly see the gloating in her expression, so he put on a humble expression and lowered his eyes: It seems that the future is long...

Although Su Xuanhe has become much more sensible than the naughty kid who first traveled through time with Su Qingluan, he is still under eleven years old. It is really difficult for him to "entertain" Su Qingluan and Mu Xingzhi, although he has done a good job - first he served them snacks, and then served them fruit tea.

"Qingluan's snacks and tea are truly unique." Mu Xingzhi took a sip of tea gracefully and put a small, delicate snack into his mouth. "This snack is also very delicious."

Su Qingluan's mouth twitched: "Because these snacks or fruit teas were all made by me..." So does her younger brother count as "borrowing flowers to offer to Buddha"?

I have to say, it feels really amazing to have the snacks I made myself served to me.

After hearing what Su Qingluan said, Mu Xingzhi re-examined the snack: the texture was delicate and soft. Since Su Qingluan said it was made by her, it must have taken at least more than three days to complete.

However, this snack is still soft and delicate, no less than those freshly made snacks. In terms of taste, its slightly sweet taste with a hint of tea fragrance is even better than the snacks of many wealthy families.

Mu Xingzhi looked at Su Qingluan: "How did you do it?" Generally speaking, this kind of tea snack with a delicate taste and soft texture will undergo subtle changes in taste even after three hours, let alone three days.

For example, in this dry and windy autumn, even if this kind of tea snack is left indoors for more than an hour, the surface texture will become slightly cold, hard and flexible, making the taste dry and difficult to chew; and if it is a hot summer, this "wind-drying" effect will be even faster; as for rainy weather, it is also not a good option, because the pastries will easily deteriorate and grow turbid gray-green mold spots.

The piece of snack in Mu Xingzhi's hand still retained its delicate taste and fragrant smell, without any signs of deterioration.

Su Qingluan had been "working" with Mu Xingzhi for a long time. When she heard him ask this question, she understood that he probably wanted to expand this "technology" of preserving food to his own army to provide more options for military supplies.

She blankly interrupted the other person's inappropriate imagination: "It's not that I don't want to say it, but it's useless to say it. It's too troublesome and expensive, and it's very inconvenient to promote it on a large scale."

Mu Xingzhi nodded immediately after hearing this and stopped asking questions. After spending several years together, he had also figured out Su Qingluan's personality. If she decisively said "not feasible" for those seemingly fantastic ideas, it meant that there was no possibility at all, and she was not exaggerating or hiding it.

The same is true this time.

Thinking of this, Mu Xingzhi still felt a little regretful - if only fresh food could be preserved for a long time...

"Unless—" Su Qingluan's next two words attracted Mu Xingzhi's attention again, "Unless you can turn Liuli into something cheaper than sunflower."

Although "cabbage" in this era is also a common dish, it is still more valuable than the so-called "cheap cabbage price" in the previous life, so Su Qingluan turned to using sunflower cabbage, which is more common and cheaper in this era, as a substitute.

In fact, Su Qingluan's ability to "keep food fresh" is based on the earliest canning principles. However, in the early days, the bottom of the glass bottle was heated to expel the air inside, and then the plasticity of the glass was used to bend the bottle mouth to insert the stopper to create a "vacuum can."

In Su Qingluan's time, glass, also known as colored glaze, was produced in very low quantities due to limitations in forging technology, making it considered a "luxury product." Naturally, it couldn't be used to make cans and bottles. So, Su Qingluan used an ordinary large porcelain bowl as a "cover," placing it inside a dish of water one inch deep and burning a candle in the middle. This way, a vacuum could be created.

And because of the water surface, it can seal out the air while ensuring that the food surface will not dry out.
