Ever since she was half-forced and half-tricked into buying the constant temperature suit, Di Lan's assistant Zhuzhu has been in a bad mood all night.

After the film festival ended that day, she took the time to check online for entertainment news as usual.

It was no surprise to see the entry for Dai Li.

Xiaohua's anonymous revelation did not cause a big explosion, but it still triggered a small-scale discussion, especially since there were more than one or two actresses who had been sold constant temperature suits by Dai Lidou.

[Today I went to bed early]: She dared to buy such a crappy dress for 500, why didn't she just go and rob it? It's also made of thermostatic material, it's so hot.

[Rabbit Bunny]: I said she wouldn’t stir up trouble for no reason. It turns out she walked the red carpet dressed like that just to promote products.

[A bald man pops up from the crowd]: Damn, this dress looks so familiar, isn’t this the dress that Dai Li put on her online store yesterday?

[A bald man pops up from the crowd]: Yes, I read that right. It’s the one that was put on the shelves yesterday. My classmate discovered it by accident, but it was reported and blocked due to false advertising. I still have the screenshots/pictures here.

[Let's get ashore safely together]: Speechless... I can feel the embarrassment just by looking at the screenshots. Look at what she wrote. I understand that Dai Li wants to make money, but she can't make money just by doing anything. She may earn dirty money, but she won't have the luck to spend it.

[Good luck on the postgraduate entrance exam]: Being reported is really justice from heaven, but it’s strange, why is there still sales volume?

[A bald man pops up from the crowd]: Oh, that’s my idiot classmate. He weighs over 100 pounds but has a rebellious bone structure.

[This is a small account]: Teacher Di Lan also bought it. I can only say that Teacher Di Lan is really kind.

[Christmas Eve Apples for You]: I can’t stand this! Is she so short of money? Why would she even lie to Teacher Di Lan?

[Open the door □□]: I feel sorry for Teacher Di Lan. I really hope that Teacher Di Lan’s kindness will not be wasted on people who don’t deserve it.

The more Zhuzhu looked, the tighter her brows furrowed.

Especially when I saw someone reveal that Di Lan also bought it.

After Di Lan finished greeting others, Zhuzhu handed the content on the phone to Di Lan.

"Look, Sister Lan, I told you not to buy it. She is indeed a liar."

Di Lan said nothing, his fingers quietly sliding across the comment page.

After looking for a while, I lost interest and returned the phone to Zhuzhu.

"I've already told you, just buy it. 500 yuan isn't a lot of money. You said it yourself, just consider it a good deed."

"I didn't expect anyone to see it. Now everyone knows you bought her clothes. If she borrows your name to sell her clothes in the future, won't our reputation be ruined by her?"

Di Lan thought about it carefully and felt that what Zhuzhu said made sense.

"Give me her clothes."

Zhuzhu took out the constant temperature suit from her bag.

When she took it out, she was a little puzzled. She had just balled up the clothes and stuffed them into the bag casually. How come they were not wrinkled at all after being there for several hours?

Shake it open and it will be as soft as new.

Zhuzhu suddenly felt that the fabric and texture seemed pretty good.

But she didn't have time to think about it and handed the clothes to Di Lan directly.

After Di Lan got the clothes, he took off his eco-friendly fur and put on the constant temperature suit.

"Sister Lan, you have to wear it." Zhuzhu was shocked.

Before Zhuzhu could stop him, Di Lan had already put his arms into his sleeves.

"You also said that she might use my name to sell clothes. No matter what, I tried them on in advance because I want to be responsible to the consumers."

Zhuzhu curled her lips: "If only she had one tenth of your sense of responsibility."

Di Lan pinched Zhuzhu's face mischievously.

Then he zipped up his clothes and shivered as he wanted to grab his fur coat to keep warm.

Suddenly, Di Lan felt that he was no longer cold. His whole body was warm, as if he was bathing in the spring sunshine.

Seeing that she didn't come to get her clothes, Zhuzhu quickly shook out her coat and said, "Sister Lan, what are you thinking about? Hurry up and put on your clothes. Be careful not to catch a cold."

"No need." Di Lan pushed his hand away.

"Ah? What's wrong with you?"

"Zhuzhu, I don't seem to be cold anymore." Di Lan couldn't believe it, as if he himself found it difficult to understand how he felt.

Zhuzhu couldn't understand it even more.

"Aren't you cold?"

“I think the temperature I’m feeling right now is very comfortable.”

"Ah? Comfortable?" Zhuzhu looked up and down at Di Lan's clothes. It was just a thin sun-protective jacket, and it didn't look like the temperature was comfortable at all.

"I want to wear it out and see it."

Perhaps the experience was too wonderful, Di Lan just wanted to wear it outside to feel it for himself.

"Sister Lan, our car hasn't arrived yet." Zhuzhu wanted to catch up, but she hadn't packed up all her things yet, so she had to pack up hurriedly.

When Zhuzhu caught up, Di Lan had been standing outside for several minutes.

She told Zhuzhu in amazement: "Zhuzhu, this dress is really warm!"

Seeing Di Lan with a rosy complexion and warm palms, he was completely different from the one who was shivering with cold and had a pale face in the conference hall.

Even though Zhuzhu still had many questions in her mind, she had to admit it.

It seems that Dai Li did not lie.

On the way to send Di Lan back, Zhuzhu also tried on the constant temperature suit. The feeling of being wrapped in the warm sun was an experience she had never had before.

After putting it on, Zhuzhu was reluctant to take it off.

She wrapped herself in her down jacket and suddenly felt that the down jacket was not warm enough.

"How come her dress is so magical? It's so strange, I won't feel cold when I put it on."

Di Lan thought for a moment and said, "I remember she mentioned something about constant temperature material. It might be the latest new technology."

"Sister Lan, go back and ask Brother Yu, he will definitely know."

Brother Yu refers to Di Lan's husband Yu Ruifeng.

"He's on a business trip. I'll ask him when he comes back."

"If it's really made of new material, I'll buy two pieces so I don't have to worry about the cold this winter." Zhuzhu felt happy just thinking about it.

Di Lan couldn't help laughing: "Isn't that little girl selling it? Just go buy it from her."

Zhuzhu felt a little embarrassed. When she thought about how she had doubted her before, she couldn't bring herself to go to her to buy it.

"Please ask Brother Yu first. If that doesn't work, I'll go find her to buy it."

As they were talking, the nanny car drove to Di Lan's residence.

It is a small five-story Western-style building.

From a distance, I saw a person waiting at the door, looking at his watch from time to time.

"Huh? Brother Yu is back?" Zhuzhu recognized Di Lan's husband at a glance and excitedly informed Di Lan.

Di Lan didn't expect her husband to come back early, so she ran out of the car excitedly as soon as it stopped.

Yu Ruifeng was very happy to see his wife at first, but when he saw the clothes she was wearing, his brows immediately frowned.

"You know you're not feeling well, but you don't dress properly. It's so cold, you only wear one layer. If you get frozen, you'll have to take bitter medicine."

"Zhuzhu, why don't you think highly of your sister Lan? I don't object to you going out to work, but you have to supervise her and not let her do whatever she wants."

Yu Ruifeng's face is definitely not a kind one. He has sharp brow bones and eagle eyes. You can tell at a glance that he is not someone to be trifled with.

Later, while serving in the fire department, his neck and jaw angle were burned, and knots grew on them, which added a fierce look to his face.

He frowned, the kind of man who could scare a child to tears.

Zhuzhu was also a little afraid of him.

Especially when he gets angry.

Zhuzhu smiled awkwardly and moved over to explain, "Brother Yu, it's not what you think. Sister Lan's clothes are very warm."

Yu Ruifeng didn't say anything. His silence clearly showed that he didn't believe Zhuzhu's words.

Di Lan quickly held his hand and said excitedly, "Look, my hands are warm, aren't they? It's because I'm wearing this coat."

Yu Ruifeng frowned in confusion. As far as he knew, Di Lan's hands had never been warm all winter, no matter how hard she tried. The doctor said that she had cold in her body, an illness she had contracted while soaking in ice water while filming in her youth, and she needed to recover slowly.

"What's going on?"

"Go inside first, and I'll tell you slowly."

Zhuzhu also followed him in, and she and Di Lan told Yu Ruifeng about the constant temperature suit.

"She said this is a constant temperature material. Is it a newly developed material?" Di Lan asked.

Zhuzhu: "Brother Yu, if this is a new material, when can it be mass-produced? I also want to buy one."

Yu Ruifeng studied the thin piece of fabric carefully and did not give an immediate answer.

After he was injured and retired, he started to engage in the manufacture and sale of fire-fighting equipment. Later, his business grew bigger and bigger, and he began to cooperate with the fire center to develop fire-fighting equipment, equipment and materials.

Therefore, Yu Ruifeng is very familiar with the new materials that have just been developed.

But he didn't say the material in front of him was good, he just felt it was very ordinary.

In fact, this material is not ordinary at all. He just tried it and found that it is indeed very warm when worn outdoors.

"What other properties does the clothing seller say this material has?"

Maybe it’s because of my job, but when I see materials, I want to analyze their performance.

Zhuzhu found a screenshot of Daili’s online store on the Internet.

Yu Ruifeng saw the promotional words above, "New constant temperature material, no matter how cold or hot it is, it keeps the temperature constant in one second when you put it on."

He frowned and muttered to himself, "It should have more than just this performance."

Di Lan covered his mouth in surprise: "Are there any other functions?"

"If constant temperature is possible, then this material's performance shouldn't be limited to constant temperature," Yu Ruifeng said firmly. "Constant temperature is just the most common characteristic among this material's additional properties."

Neither Di Lan nor Zhu Zhu quite understood what was said.

But Yu Ruifeng's interest has been ignited.

"Xiao Lan, who did you buy this dress from?"

Dai Li returned to the apartment hungry.

There was no seat prepared for her at the film festival dinner, and she came back directly before the event was over.

"I won't go to this kind of activities in the future." Dai Li said this to Sister Tu as soon as she came back.

It's so boring. The people around me are either pretending to be nice or trembling and trying to pose.

It would be better to stay home and do something useful.

Sister Tu no longer expects her to meet a famous director at the film festival. Now she just wants to know how many clothes she has sold.

Dai Li opened the fried rice noodles she bought downstairs and said as she ate, "I sold one."

"I sold one piece. That's great! I thought I wouldn't be able to sell any."

Dai Li:......

"Then you still want to pack three for me?"

Sister Tu smiled and said, "It's better to be prepared, but I didn't expect you to sell so smoothly."

Dai Li remembered the look Zhuzhu had given her at that time.

"It's not going well. Maybe the product will be returned in two days."

"Not really. After wearing your constant temperature suit, would you be willing to return it?"

Dai Li shrugged.

It's obvious that Di Lan is very particular. Buying her clothes is out of courtesy, but it doesn't mean she will wear them.

Her assistant is not an easy person to deal with. He might think of what happened today in a couple of days and come back to cause trouble.

Not long after, Sister Tu received a call from Zhuzhu unexpectedly.

Sister Tu just wanted to curse at that time, damn, he actually came to return the goods!

The other party specifically asked for Dai Li and didn't give her a chance to speak, so Sister Tu had no choice but to give the phone to Dai Li.

And told her with lip language: "Returned goods..."

Dai Li put down the electric screwdriver in her hand and answered the phone calmly.

Unexpectedly, the person was not Di Lan's assistant Zhuzhu, but a man.

"Hello, are you Miss Dai Li?"

"I am."

"Excuse me for calling you so late at night. I'm Di Lan's husband, Yu Ruifeng. Excuse me, did you sell my wife that constant temperature suit?"

"It's me, do you want to return it?"

"No, you misunderstood. We tried the clothes on and are very satisfied. I do have a question for you. Who developed the material of this clothes? Besides keeping the temperature constant, it should have other properties, right?"

Dai Li raised her eyebrows, thinking that the other party seemed to be an expert.

"Of course. The main properties of the material are antifreeze, fire resistance and toxic smoke filtering. It is not flammable, but can be degraded by soil."

Yu Ruifeng's heart suddenly skipped a beat and an idea popped into his mind.

He asked with a trembling voice, "I want to ask, can it be used for firefighting?"

Dai Li could already roughly guess that the other party's industry was related, and silently raised a smile: "Of course, constant temperature materials were originally used for firefighting."
