Xia libing took that pair of chopsticks and tried to do the action of sandwiching vegetables, as expected.

Nana has praised the chopsticks that she sent to Kun more than once in the group. Before, she often didn't catch the chopsticks accidentally, especially when eating out with pointed chopsticks. But with the chopsticks sent to Kun, she was very handy, especially stable.

Nana even said that this pair of chopsticks may be one of the culprits for her weight gain in recent months

Although the chopsticks on Xia libing's hand are almost different from Nana's, they are much longer than ordinary chopsticks. The back is square, and then gradually changes to the front circle. Compared with the pair of chopsticks that Xiang Kun gave to Nana, the chopsticks have many sharp heads, but in Xia libing's hands, they are very flexible, labor-saving and harmonious Hands.

In Xia libing's view, eating with chopsticks is a "one handed, high frequency, laborious lever movement".

Therefore, from the perspective of simple work, the lighter the material of chopsticks and the closer the center of gravity is to the fulcrum, it is the best. Of course, there are many other factors to consider when using chopsticks.

Although most people can use chopsticks, in fact, everyone's way of using chopsticks may not be the same. Parents usually don't pay too much attention to correct them when they are young. Anyway, as long as they can clip them up, just like writing with a pen or typing with a keyboard, there are also various hand techniques. Therefore, different chopsticks are suitable for different people, different hands and different postures The degree of response is still different - although the same can be served with vegetables.

For example, Nana's way of holding chopsticks is quite "nonstandard". Similar to holding a pen, the ends of chopsticks often cross when picking vegetables. Therefore, the front end of chopsticks can only be closed at most. The two chopsticks are parallel. It is difficult to fully close the front end with those pointed chopsticks, and it is easy to clip vegetables stably. Therefore, the chopsticks sent to Kun are flat headed and she uses them It's very handy, and the length and center of gravity are just right.

However, Xia libing's way of holding chopsticks is relatively standard. The main reason is that the chopsticks on the top are moving and opening. No matter whether the chopsticks are opened or closed, the tail keeps a little distance. Therefore, the pointed chopsticks are easy to use. Not only will the overall weight of the pointed chopsticks be lighter and easier to use, but also the center of gravity will be closer to the fulcrum, so it is easier to carry out some fine operations, such as picking fish bones.

"How is it going?" Looking at Xia libing holding chopsticks, he asked with a smile to Kun.

Xia libing looked up at him and nodded: "very good."

She pondered: it is obvious that when Xiang Kun delivers chopsticks to different people, he has the habit of "customizing" different people. But according to the feeling of using the chopsticks, the degree of "customization" is a little too high.

The method of holding chopsticks is suitable for pointed and flat heads. It is also said that it can be judged by careful observation. However, the chopsticks sent to Kun are very suitable in terms of length, center of gravity and thickness. It is very labor-saving and free to control the movements of clamping, opening and closing, which requires a lot of observation.

At least Xia libing thinks that if she is the one who makes chopsticks, she does not consider the difficulty of making chopsticks. She only needs to collect the data of using chopsticks, which requires a lot of observation samples and detailed adjustment. It is best to have the user to cooperate, through the use of semi-finished products, feedback again and again, fine-tuning again and again. In this way, it is possible to achieve the current degree of fit.

But Xiang Kun didn't do that. When she left Tongshi a few days ago, she suddenly said that she wanted to send her chopsticks. Now there are finished products. Judging from the details of the chopsticks, they should have just been made. That's right. His performance is obviously sure that the chopsticks are perfect and will fit his own way of use. He has not received his own feedback once. Why can he be so sure? Why are you so confident?

Xia libing took out the chopsticks and played with it for a while, then took it back into the box, and then put the box into the backpack that Xiangkun put her clothes in.

She has other doubts, but she will have to wait until she gets back.

"Don't you order a drink?" Xia libing looked at the American coffee in front of him and asked.

"I just came over from dinner. I'm very full." Back to Kun.

Xia libing also did not ask him what to drink, but said: "let's play a game."

"Play games?" Xiang Kun was still thinking about what kind of excuse to let Xia libing put his chopsticks in his bedroom after he went back tonight and tried to get closer to her bed. Suddenly he heard such a proposal and was greatly surprised: "what game do you play?"

Xia libing took out a one yuan coin from his pocket and said, "let's play and guess coins."

Xiang Kun can see at a glance that the one yuan coin lying in the palm of her hand is the one she wanted to go to before she took her to the motor train in Tongshi town a few days ago.

Guess the coin?

Isn't this a bonus?

When Lao Xia was in Tongshi Town, she offered to ask for coins. Xiang Kun knew that she saw that there was something wrong with Nana's "lucky coin". Now, is this a direct verification?"Guess what Xiang Kun said with a smile, "you can't just play alone. It's interesting to win or lose."

Xia libing nodded: "then lose once, please a meal."

“OK。” Xiang Kun smiles secretly. He doesn't mind being found out that there is something wrong with the coin by Lao Xia. On the contrary, he expects Lao Xia to "find" something on the coin.

So, guess the coin or something, he's not going to let it go.

Lao Xia asked him to guess a few times, so he was ready to invite a few meals, although he didn't like to eat.

Xia libing holds the coin in his hand, carries it back to his back, and exchanges it for a while, passing it from the right hand to the left hand, and then from the left hand to the right hand, and then puts his fists in front of him to let him guess.

Xiang Kun didn't hesitate and disguise at all, and he made a virtual point of her right fist.

Summer from ice nodded, very frankly said: "I lost." There was no sense of surprise or chagrin, as she had known for a long time.

Four times in a row, Xiang Kun still guesses seconds every time.

But Xiang Kun is a little funny that at the beginning of the third time, Xia libing secretly replaced the "super sense connection" Coin - put the coin under his thigh and pressed it, and then replaced it with an ordinary coin.

Xia libing's technique is actually very secret and fast. However, Xiang Kun has a "super sense connection" with that coin. Basically, he can sense its exact position at any time, so he immediately knows when it is replaced.

Although there is no way to open the coin by "super sense connection", Xiang Kun can still easily guess which hand the coin is held in with his "strength".

He can switch the infrared thermal imaging visual mode to observe. Thermal imaging is not X-ray, and can not directly penetrate to see the situation in the fist. However, there is a slight difference in blood flow between the fists holding coins and those without coins. Therefore, there is a difference in heat. If there is a preset target, he can immediately find the difference between the two and make a judgment.

So just like guessing the coin of "super sense connection", there is no hesitation or mistake.

After a total of five times, Xia libing stopped playing with Xiang Kun. He put away the coins and said, "I owe you five meals. When do you have time to tell me that I have prepared the ingredients, you come to my house."

Xiang Kun was stunned for a moment, and then asked, "that Let me ask, you have the ingredients Who's going to do that? "

"You." Xia libing said very simply, firmly and naturally.

"Ah, ah? It's not right... " Xiang Kun pointed to himself, and then pointed to Lao Xia, comparing five fingers: "it's me, I won you, five meals!"

Xia libing nodded: "yes, I'll treat you to dinner. I bought the ingredients and invited you to come. You don't want to eat them raw, so you can cook them. Salt, oil, other seasonings, pots and other cooking utensils are also available. When you came last time, you bought them. If you need anything, you can tell me and I will prepare them in advance. Of course, you can eat it raw. "

Looking at Lao Xia's serious and natural way of saying this, he couldn't help crying and laughing to Kun: "you're not old Xia, are you? You are Yang Laosan in old summer skin... "

Summer Li ice suddenly stare big eyes, a face "surprise" expression to look at him: "how do you see it?"

Xiang Kun laughs. Lao Xia is an excellent comedian. He is worthy of being a cousin of Yang Laosan. Most of the time, he is indifferent and estranged, but the gene of doubi in his bones is the same. However, from the perspective of various sensory information monitoring, Lao Xia still has no big emotional fluctuation from the beginning to the present, at least from the physiological feedback of heartbeat, breath, smell and micro expression, which is the same as before.

In contrast, Xia libing's mood will really have a big and obvious change, or when eating.

"You are Xiao Kun? " At this time, a woman about 40 years old, who was diagonally opposite a table, looked at Kun for a few times, then suddenly got up and came over and asked him directly.

Xiang Kun Xun's reputation went and made a surprised expression. It seemed that he had just seen her, and then turned into a surprise: "ah! My cousin, what a coincidence

This middle-aged lady is Xiang Kun's father's cousin's daughter-in-law, that is, his cousin's wife, just entered the coffee shop not long ago.

In fact, Xiang Kun noticed her as soon as she came in. However, according to Xiang Kun's judgment, the last time she saw herself was during the Spring Festival last year. Now he has changed so much, not to mention ordinary relatives. Even his mother didn't recognize him when he first met him, and his cousin would not recognize him, so he didn't intend to take the initiative to say hello.

But unexpectedly, my cousin really recognized it?

"When I was two or three, I went to the table with my aunt. I heard her say that you are playing" personalization "and have a bald head. As soon as I saw your head, I remembered what my aunt said. I thought it was time for you to come back for the Spring Festival. The more I looked at it, the more familiar I felt. I didn't expect it was really you As she spoke, her gaze swam between Xiangkun and Xia libing. Her eyes narrowed gradually, as if hiding her flaming fire of gossip.

"Yes, I just arrived at Erythrina in the afternoon. Do you come to have a drink with your friends, sister-in-law?" Xiang Kun was staring at the table where his cousin came. The middle-aged lady with eight trigrams on her face gave a friendly smile and nodded her head as a greeting."Yes, it's a coincidence that some of our old classmates and sisters come out to talk! This beautiful lady is so beautiful. Is she My cousin looked at Xia libing and asked.

Pointing to Kun, she pointed to the backpack now placed at the feet of Lao Xia and said, "this is my friend's sister, who works in Erythrina. When I come back, my friend asked me to bring her something."

"Oh, my friend's sister, should take care of, should, you chat, you chat ha! You should not go back to work until after the ninth day of junior high school, right? Remember to come home sometime after the new year. Haven't you come to my house for a long time? You two nephews have been greedy for your red envelope for a long time! " After she said a few words with a smile, she went back to her classmate's table, and then from time to time handed over a look of "come on", "I'll take good care of you" and "hey hey hey".

Xiang Kun looked at his mobile phone helplessly and said to Xia libing: "it's not too early. I'll send you back. What's your arrangement for tomorrow evening? Have you been to your uncle and aunt's house? "

Xia libing took the knapsack that Xiang Kun brought her to get up and said, "on duty."

"Worth one night?" Ask Kun.

"It's worth one night." Xia libing affirmed.

"Well, I'll see later tomorrow night and send you some supper?" Said Xiang Kun.

"Good." Xia libing nods.

Two people walk out of the coffee shop, originally said to send Xia libing back to Xiang Kun, but after a look at her, said to her see you later, and then went directly in the opposite direction.

Xia libing's expression did not change at all. After saying goodbye, she still went to the community where she rented, and did not ask Xiang Kun or any surprised performance.

The neighborhood she lived in was not far away from the cafe. She could walk about 15 minutes on foot. So she didn't call a car and walked with her bag on her back.

Before walking for a while, she picked up her mobile phone and saw a message sent to Kun on wechat: "someone is tracking you. Don't look back. Keep going home. I'll see what he wants."

Xia libing's expression is still very indifferent. After returning to a OK expression, she continues to walk home without any illness.

Not far away, the young man who used to play mobile phones in the corner of the outer wall of the coffee shop looked up and saw Xiang Kun's back disappear at the corner of the street, and then walked towards the direction of Xia libing's departure, and at the same time, he was sending messages with his mobile phone.

But what he didn't know was that Xiang Kun stopped at the corner for a moment, and then confirmed that the man didn't look at the side of the road through the glass reflection of the car, and then came back.

Just arrived here, before entering the coffee shop, Xiang Kun noticed the man who was cold like a quail in the water outside, playing with his mobile phone.

Because he found that the man seemed to be playing with his mobile phone, but his attention was in the direction of the cafe. But at that time, he didn't know that this man was aiming at old Xia, so he didn't care too much. But when he and Lao Xia came out, they noticed that the man's glance was locked on them, and his body was obviously tight. He immediately realized that this man was staring at Lao Xia outside the coffee shop.
