"You mean you took the tour of the courtyard but went out for a spring outing?" Xiaomei asked.

"What's wrong? Is there any problem?" Su Yue replied.

"And I only brought food for two people? Why are they from two people?" Lulu asked at this time, and then her stomach roared.

"You all know that I am a sports student. It's normal for me to eat more than a girl? It's not too much to have more than a boy, right? So for girls, it's the amount of two people. Are you satisfied with this answer? And why do you question me together now? I think if I admit it last night, everyone would probably be hungry again this morning. Isn't this kind of thing effective the later it is? After all, the food is not enough." Su Yue said and opened her schoolbag, which contained six bentoes.

There was a universe in Su Yue's schoolbag, and it was all displayed in front of everyone at this time.

I was very surprised after seeing it. It was a double-layer structure.

You can see that the inside of the schoolbag is a layer of wool coat, which is not common today.

The sleeves and collar of the military coat are completely sealed and filled with cotton, and layers of ice packs are placed on the surface.

These ice bags are ice tiles made of water in advance and then frozen in the refrigerator. At this time, they are all-roundly attached to the outside of the entire schoolbag, and there are six boxes of Locks wrapped around Locks, which are also frozen into ice cubes.

Lulu was really hungry, and after touching her, she said helplessly: "This thing is cold."

I looked at the opening and said, "I have heard that the old man who used to sell ice strips. In the summer, there is no refrigerator, and it can be stored for a long time. Ice strips can be sold on the street. How did you think of this thing, Su Yue?"

"This is what you are planning to use for a spring outing, isn't it a scam? To put it bluntly, you are more like a famine." Xiaomei felt incredible when she looked at it.

At this time, Xiaowen reacted and said, "I have learned that there are three ways of heat transfer: conduction, convection and radiation. Quilts, down jackets and thermos cups are used to isolate objects from the outside air through poor thermal conductivity materials or vacuums, reducing heat conduction and heat convection between the two. It is not surprising that you can think of this method. But can you explain why you are ready in advance, just like you know something like this will happen?"

Lulu found something at this time and reached into her schoolbag and was startled: "No, the ice will definitely melt at room temperature. But the schoolbag seems to be still cooling very cold."

Indeed, it has been more than twenty-four hours since yesterday afternoon to now. It is impossible to keep insulated for six hours so exaggerated. Such a long time can only prove that the schoolbag can be kept below at least four degrees.

Su Yue shook her head at this time: "There are semiconductor refrigeration films in the four corners inside, part of which is from Taobao, and part of which is removed from the water dispenser. Three yuan per piece, the cost here is about 30 yuan. As for the power generation, it is very simple not to tell you. I have a power bank and electricity, but after I tell you, you will find that I have food. The problem now is that I am willing to share with you what I have. Don't ask so many strange questions, put your heart in your stomach. I won't harm you, but I don't want to explain."

Su Yue said as she took out two boxes of bentoes that were still cold.

"How do you heat the cold?" Xiaomei asked in confusion.

At this time, Su Yue took out a bag of powder from the interlayer of her schoolbag, and put a bag of almost melted ice cubes on the fan of the heat conductor flake on the side of the schoolbag. The fan of the heat conductor flake absorbs heat and releases heat. At this time, the ice cubes turned into bags of water.

Pour the bag of water into the bag of powder and it will soon start to heat up or even smoke.

Su Yue placed the entire upper and lower two-layer box and soon began to react.

Xiaowen explained almost immediately: "Quicklime was heated by water. Is this thing taken out of the self-heating bento?"

"No, it was removed from the expired warm baby. Take the road and bridge a little further." Su Yue retorted.

I did it naturally, and soon I saw thick smoke rolling.

About fifteen minutes later I uncovered the lid and two boxes of bento appeared in front of me.

I immediately returned to everyone with the food.

Su Yue said at this time: "I suggest that this is the case, those with the ability to handle the processor. Shu Xiao and Lu Qiao eat a box. The rest are the ones like us who are sickly Xiaowen, who are full and have no energy, and Lingling, who has been hungry for too long, and I, let's divide it into one box for four of us."

Obviously no one has any objection to Su Yue’s request.

Everyone was quite pleased to be able to get food.

Then Su Yue took out a pack of ice cubes and placed the ice water in front of the fan of the previous heat conductor. After dinner, a bag of ice water was divided into one mouthful of each other.

If everyone was still living in despair the previous second, they were relieved a lot in this second.

But in contrast, everyone looked at Su Yue after eating and drinking.

"You are a sports student, and I know that your grades can barely be maintained at the passing line. It's not that I suspect you can't make these things, but that you are a little incredible with these things at the right time, right?" Xiaowen asked.

"Xiaowen is what I want to say. No wonder you don't want anything we eat yesterday." Xiaomei said.

"If you are not wrong, you will not have any problems if you are locked up here for three days. And you also brought two people to the limit. If I read correctly, you asked Lu Qiao to go to the gymnasium at the beginning." Lulu also expressed her thoughts at this time.

"You... we have been arguing these few times, and you have been repeating it all the time. We said we shouldn't have followed us at that time, we didn't run in panic. Maybe we wouldn't have thought of hiding in the warehouse, but it seemed that you found it for us. The door here is so heavy, and now it's the situation. So if we don't follow us, what will happen to you and Luqiao in the gym? You two will be locked up in this utensil? Your food is just enough for three days, right?" Shu Xiao pointed the idea of ​​the matter at this time.

I was thinking at this moment, covering my mouth and nose, bent down and picked up the volleyball that had been rolled aside by Su Yue before, so I was so good that I was on the shelf at this time.

At this time, the light of Xiaowen just shone on Su Yue and the other four below, and I tried to throw the volleyball at Su Yue again.

Su Yue acted almost the same as before and blocked her face with her hands, and begged to the ground with her arms obliquely.

This action was not a reaction that an athlete could make at all. I stepped forward and grabbed Su Yue's hand again.

"Luqiao, why are you smashing Su Yue?" Xiaomei said in confusion.

"What are you doing to grab my hand?" Su Yue also retorted at this time.

I spoke, "I actually have a problem. Su Yue is the volleyball school team. I believe that as long as a person who has received a little training, it is impossible for him to catch a flying ball. After all, it is not certain how many volleyballs he has to play back every day when he is training. The first time it was because of the lighting problem, there was no problem with the lighting this time. Also, although I have never touched Su Yue's palm, I know that she usually has to wrap gauze and finger covers on her hands during training. When you pulled me to the gym, there was no calluses on her hands. At first I was surprised, but now everything is understandable. You are just a person who looks very similar to Su Yue and knows that Su Yue is used to it."

As soon as these words came out, Su Yue smiled.

"Su Yue, why are you laughing at?" Xiaomei looked at Su Yue with a little cunning look.

"You are very smart, most of them guessed correctly. I am indeed not Su Yue, but you should understand who I am Luqiao?" Su Yue looked at the strawberry-patterned card taken out of the compartment of her schoolbag.
