Qin Feng mentioned a theory in economics called the marginal diminishing effect.

Qin Feng said to Li Lingjia, "Do you know what marginal decline is?"

Li Lingjia replied, "I have learned it, but I have forgotten it."

Qin Feng explained: "That is to say, no matter what happens, people's satisfaction will not always rise, it will reach a peak, and then tend to level off, just like drinking soda, the first sip is always the sweetest and the most satisfying."

Li Lingjia asked, "You compare love to drinking soda?"

Qin Feng replied: "Love is actually the same, some people say that the ambiguous period is the peak of love, because the ambiguous period is when love begins to form."

Li Lingjia looked at Qin Feng and asked, "So, what do you want to express?"

Qin Feng took a deep breath and said, "So, I think every day is an ambiguous period, in this way, the freshness will never go out of style."

Li Lingjia immediately picked up the pillow, smashed Qin Feng wildly, and said, "It turns out that you are waiting for me here, is this the reason why you have not officially announced it? Scumbag!"

Qin Feng immediately said, "Who said I didn't make an official announcement? I'm ready to make an announcement."

Li Lingjia asked excitedly, "When and with whom will it be announced?"

Qin Feng frowned and said, "Why are you so excited, it's definitely not with you."

Li Lingjia said angrily, "It's okay for me to ask?"

Qin Feng replied, "When my parents come back, I will make an official announcement during the Chinese New Year."

Li Lingjia smiled and said, "It's amazing."

Qin Feng asked, "I officially announced it, you seem to be very happy?"

Li Lingjia replied: "Yes, after the official announcement, you can't blatantly flirt with your sister, you know, now watching you flirt with your sister all day long is even more uncomfortable than my aunt."

Qin Feng said in a cold voice, "Are you cursing me every day behind my back?"

Li Lingjia smiled and said, "Yes, I also gave you a villain, how about it?"

Qin Feng said, "No wonder I sneeze every day."

Li Lingjia said, "Hurry up upstairs, Qingqing will thank you for waiting for the flowers."

Qin Feng got up, held the flowers, and said, "It doesn't matter if the flowers are gone, as long as they don't ...... early Haha, forget it, don't talk about it."

Li Lingjia angrily scolded: "Qin Feng, get out of here."

It turns out that men are not bad, women are not loved.

The more bad boys like Qin Feng are, the more girls like them.

Soon, Qin Feng came to the Qingqing room and knocked on the door.

There was no movement.

"Qingqing, are you asleep? Can I go in?" Qin Feng asked.

There was no sound in the bedroom, and Qin Feng thought that Qingqing was asleep.

Just as Qin Feng was hesitating to go in, Jiang Xiaqing opened the door.

At this moment, her eyes were red, and she looked pitiful, like a wronged kitten.

Qin Feng hurriedly took out the blue roses he had bought in advance.

"Give you Flowey." Qin Feng said with a hippie smile.

Jiang Xiaqing did not reach out to receive the flowers, but grabbed Qin Feng's hand and pulled Qin Feng into the bedroom.

In the dimly lit room, only the mood light at the head of the bed is on.

Jiang Xiaqing hugged Qin Feng quietly like this, choking up and crying.

Qin Feng's heart softened suddenly.

"What's wrong? Clear? Is it because I didn't reply to your message, and I'm angry? Can I examine myself?" Qin Feng comforted.

Jiang Xiaqing said, "No, I'm not angry with you, you should have your life, I shouldn't force intervention."

What Qin Feng is most afraid of is that the girl is not angry, if she really wants to be angry, the problem is very easy to solve.

Qin Feng could only see the move, and asked tentatively, "Then why are you crying? Missed me? Or ......"

Suddenly, Jiang Xiaqing let go of Qin Feng and whispered, "Qin Feng, this may be the last time I will hold you, in the days without me, you must be well, don't get a hangover again, a hangover is equivalent to an acute hepatitis."

Qin Feng was confused when he heard this, and he hurriedly asked, "Why is it the last time?" What do you call a day without you? I'm a little confused, Qingqing, what the hell is going on?"..

Jiang Xiaqing wanted to speak and stopped, she wiped her tears with her hands, turned around and sat on the edge of the bed, and said, "Qin Feng, don't ask, don't come to me in the future, today is the last day."

Good guys, it's a big game now.

Jiang Xiaqing wouldn't say such things for no reason, there must be something hidden in this that Qin Feng didn't know.

Qin Feng came to Jiang Xiaqing's side and comforted him softly, "Qingqing, I will always be a shoulder you can rely on, so if you have anything to say, you can tell me without any worries."

Jiang Xiaqing looked at Qin Feng with teary eyes, and said in a choked voice, "Brother, I have a terminal illness."

As soon as these words came out, Qin Feng chuckled in his heart.

Qin Feng's brows furrowed into twist, and he asked nervously, "What nonsense are you talking about? How did you get a terminal illness?"

Jiang Xiaqing said, "I didn't dare to tell anyone, including Jiajia, I was going to check it alone tomorrow."

Qin Feng asked with a serious expression, "What is uncomfortable, tell me, I am the doctor."

Jiang Xiaqing whispered: "My chest is uncomfortable, and there is a small pimple, it hurts when I touch it, I checked it on my mobile phone, and said that it was that, and there is not much time left for me."

Qin Feng said embarrassedly, "Self-check on the phone? Don't scare yourself if that thing isn't accurate."

Jiang Xiaqing said: "The mobile phone said that the pimple is a metastatic lymph node, Qin Feng, I know very well that if the tumor metastasizes, it will first metastasize to the lymph."

Qin Feng asked, "Does that little pimple hurt?"

Jiang Xiaqing replied, "It hurts when you touch it."

Qin Feng asked again, "Is the lump hard?"

Jiang Xiaqing shook his head and said, "It's not hard."

Then, Qin Feng said in a serious tone, "I'll check it for you, is it okay?" I promise that I will only check your body and will not take advantage of you."

Jiang Xiaqing nodded and said, "I believe in you, Qin Feng."

Subsequently, Qin Feng carefully checked Jiang Xiaqing and concluded that she was not terminally ill.

Qin Feng wiped Qingqing's tears with his own hands and said, "If you feel uncomfortable in the future, tell me first, go to the hospital second, and finally remember, don't check your mobile phone, what is often listed on your mobile phone is the worst case, you are just an ordinary fire and inflammation, not a tumor at all."

Jiang Xiaqing whispered, "But I also have small bumps under my armpits, are they lymph nodes?"

Qin Feng replied: "Yes, lymph nodes are immune organs in the human body, when there is inflammation in the body, there will be swelling, for example, we usually have bacterial infections, colds and fevers, lymph nodes will swell, generally in this case, lymph nodes, you will feel pain, and its texture is smooth, like a small ball, moving back and forth under the skin."

Jiang Xiaqing listened very carefully, and she asked again, "What does lymph node metastasis mean?"

Qin Feng continued to explain: "If it is a tumor metastasis, the lymph nodes will also be swollen, but in this case, the swelling is often painless, there is no pain at all, and the lymph nodes will be very hard, just like stones, understand?"

After Jiang Xiaqing listened to Qin Feng's words, it was like taking a reassuring pill.

She threw herself into Qin Feng's arms and said excitedly, "Qin Feng, then I don't have to leave you, it's good."

Qin Feng touched her head and said, "Silly Nizi, you scared me to death, I thought you were really terminally ill."

Jiang Xiaqing wiped away her tears and asked with a smile, "What if it's true?"

Qin Feng hurriedly said, "Hurry up and give me a bah."

Jiang Xiaqing was obedient and obedient, and snorted three times in a row.

Afterwards, Jiang Xiaqing said again, "Qin Feng, will you dislike me for being too stupid? It's stupid."

Qin Feng smiled and asked, "Have you ever been out today?"

Jiang Xiaqing shook his head and said, "No."

Qin Feng nodded and said, "That's really stupid

It's home, hahahaha."

Jiang Xiaqing sighed and said, "Qin Feng, you laugh at me, I ignore you."

Qin Feng hugged her and said, "Wait for me, I'll go get a silver needle and give you a few stitches, tomorrow, I'll accompany you to the hospital for a comprehensive examination, symptomatic medicine, and it will be fine soon."

Jiang Xiaqing said shyly, "Qin Feng, if you prick a needle, where are you going to pierce it?"

Qin Feng didn't answer directly, but stretched out his finger and pointed.

Jiang Xiaqing said nervously, "Qin Feng, don't forget it, if it's just a small problem, I can bear with it and go get the medicine tomorrow."

Qin Feng said: "Small problems, if not treated in time, it is likely to develop into a major problem, what about me, the doctor is benevolent, I want you to recover as soon as possible, but I didn't expect you to be precautionary against me, alas, my heart is cold."

Jiang Xiaqing hurriedly said, "Qin Feng, don't get me wrong, I didn't guard against you, I'll cooperate with you, is it okay?" I fully cooperate with you."

Qin Feng smiled and said, "It's pretty much the same."

Soon, Qin Feng took the silver needle.

Jiang Xiaqing also changed into light pajamas, lay on the bed, and waited quietly for Qin Feng.

For half an hour, Qin Feng was engrossed, and sweat flowed from his forehead.

Jiang Xiaqing felt much more comfortable.

After receiving the needle, Qin Feng washed his face and said, "In the past half month, don't eat spicy, don't drink, and don't stay up late."

Jiang Xiaqing obediently said, "Okay, brother, I will listen to you."

This brother made Qin Feng very happy.

However, Qin Feng was not lost in this elder brother.

Qin Feng said soberly, "Come on, pay the medical bills."

Jiang Xiaqing asked curiously, "Medical expenses? What are the medical expenses? Do you still charge for the two of us?"

Qin Feng nodded and said, "Of course, this is the rule."

Jiang Xiaqing said, "Okay, how much is it?"

Qin Feng smiled evilly and said, "I don't want money."

Jiang Xiaqing covered his chest and said, "Qin Feng, you don't want money, do you want someone?"

Qin Feng replied, "Yes, kiss me, this is not too much to ask, right?"

Jiang Xiaqing said shyly, "Then come over and let me kiss it."

Qin Feng said happily, "Okay."

Qin Feng walked in front of Jiang Xiaqing, the two were thirty centimeters apart, and under the ambiguous light, everything seemed so beautiful.

Qin Feng's eyes stared at Jiang Xiaqing, Jiang Xiaqing was very embarrassed.

Jiang Xiaqing said shyly, "Qin Feng, how can anyone kiss with his eyes open? You close your eyes."

Qin Feng smiled and said, "OK, no problem."

Next, it's time to witness the miracle.

Just as Jiang Xiaqing was about to kiss him, Qin Feng suddenly said, "Wait a while, it's a little hot in your room, I'll take off my coat first, let's continue."

Jiang Xiaqing thought to himself: What a bad man.
