Lang rode a bamboo horse roaring

"I'm sorry, I'm a little late. The number theory test was delayed by 5 minutes." Su Siting hurried into the cafeteria and sat down opposite Bai Zhou.

She and Bai Zhouyi participated in the International Mathematics Olympiad and were admitted to the same university. They are classmates again, but their research directions are different, and it is not common at ordinary times. The appointment at this moment is because it will be another month. It was Su Siting's birthday, and Lanshan was far away in Paris, so he specially asked Bai Zhou to bring a gift there, and told Bai Zhou to say hello to himself.

"It's okay." Bai Zhouyi took out the gift box from his bag and handed it over, "Lanshan wishes you a happy birthday."

"Wow, thank you!" Su Siting accepted it with a smile, and said pleasantly after opening it, "Perfume, this is the first time I have received such a beautiful gift."

She shrugged to Bai Zhouyi and joked, "There are always people who think that girls who study mathematics don't like this kind of 'superficial' stuff."

Bai Zhouyi said: "Just like it."

Su Siting looked at the gift box fondly for a while, then raised her head and asked, "How is Lanshan?"

"It's pretty good." Bai Zhouyi said, "I had an operation, and I almost couldn't even walk."

"..." Su Siting paused when she received the gift box, and when she raised her head, her expression was subtle, "Okay... where are you?"

"Mentality."

"..." Su Siting observed Bai Zhouyi for two seconds, and said clearly, "He did the operation without telling you?"

Bai Zhou hummed flatly.

"Sure enough, it's Lanshan..." Su Siting sighed, and for the sake of the perfume, she dared to say something for Lanshan, "Maybe it's because I'm afraid you're worried, but it's also a good intention. Don't be too angry."

Bai Zhouyi said, "I'm not angry."

Su Siting teased at his cold face, smiled and said nothing.

While the two were chatting and eating, Bai Zhou's cell phone kept ringing, and he kept sending WeChat messages. Lan Shan was extraordinarily hospitable after being "cold war". As soon as the break time came, he started bombarding with messages, emoticons mixed with selfies and cold jokes hair.

Bai Zhou turned a blind eye, Su Siting looked at his phone a few times, and finally couldn't help reminding: "There is a message."

"It's okay." Bai Zhouyi said.

"Do you want to mute it?" Su Siting suggested.

Bai Zhou flipped his phone on the table and said, "It's okay."

Su Siting: ...

She probably guessed who the news was, and she mourned for Lan Shan for a second in her heart.

The meal was almost finished, and Bai Zhouyi returned a message to Lan Shan, saying that he was having dinner with Su Siting.

Lan Shan sent a series of exclamation points, and the next second, a voice call came.

Bai Zhou died straight away.

Su Siting looked at him strangely, and was wondering, "Is it Blue Mountain?" when her cell phone rang.

She took out her phone, glanced at someone, was stunned for a moment, looked up at Bai Zhouyi, and then picked it up: "Hello."

"Tingting!" Lan Shan called affectionately, "Long time no see, how are you?"

Su Siting was covered in goosebumps when he shouted, and said, "It's fine, how about you, I heard from Bai Zhouyi that you were injured."

"Listen to him talking nonsense..."

Bai Zhou looked at Su Siting on the opposite side with sideways eyes, hummed a few times, and finally agreed, and handed over the phone: "Lanshan let you pick it up."

It turned out that it was the idea of ​​playing around.

As soon as Bai Zhou took it, he said lightly, "Hello?"

"What are you doing?" After finally getting on the phone with Bai Zhou, Lan Shan asked nonsense in a cheerful voice.

"Have a meal."

"Did you eat well?"

"good."

"I miss you!"

"..." Bai Zhouyi didn't respond, and said indifferently, "There are still three days until the end of the Cold War."

"..." Lan Shan was listless, and said pitifully, "Bai Zhouyi, you are so cruel."

"Yeah." Bai Zhouyi said, "It's dead."

"Hello—" Lan Shan continued to say, but Bai Zhouyi had already hung up the phone.

He returned the phone to Su Siting and said, "Thank you."

Su Siting put away her mobile phone and looked at him teasingly: "You're laughing."

Bai Zhou closed his mouth and said calmly, "I didn't."

The timing of Bai Zhouyi's birthday is very awkward. The date is one week before the final exam. All classes have been suspended during this time period. The time left should have been used for review, but Bai Zhouyi ran to Paris without looking back.

I ran back the day before the first exam.

Fortunately, mathematics is not something that can be forgotten after three days of learning. Bai Zhouyi still easily completed the paper, and was the first to step out of the examination room with the envious eyes of his classmates.

After more than a week of exams, the school completely let him go.

For a top student like Bai Zhouyi, the vacation is just the beginning of another stage of study. As an undergraduate who was exceptionally admitted to the Chinese Academy of Mathematics, Bai Zhouyi will participate in various seminars and learn various kinds of topics.

But before that, he took advantage of the rare vacation to return home.

"Is the coffee boy okay?" Pan Shi was very happy when Bai Zhou went back. She sat down and asked Lan Shan at the first meal when she reunited with her son.Fortunately, Lan Shan is the godson and daughter-in-law of the Bai family, and he is an "insider" both emotionally and rationally, so Bai Zhouyi will not feel offended.

Pan Shi asked very carefully, "How is he eating, is he sleeping well, is he injured?"

"Mom." Bai Zhou put down his chopsticks and said helplessly, "Lan Shan is also an adult."

"Adults should also pay attention to their health." Pan Shi said, "Your father just doesn't pay attention. Recently, he keeps complaining about his back pain, and I dare not give him a casual massage. He works too hard. I will give you the money to marry his wife." If we earn it, we will retire and enjoy ourselves.”

"Did the physical examination result come out?" Bai Zhouyi said, "Dad will rest when he is tired. Don't worry about me. I can take care of myself."

"There is no result." Pan Shi nodded his head, "How can I not worry about you, you have such a boring personality...Which girl would like to be with you in the future."

Bai Zhouyi was noncommittal: "He also works overtime today?"

"He won't work overtime one day." Pan Shi smiled and sighed, the phone rang, she looked at the screen and smiled, "Yo, say Cao Cao Cao Cao is here."

"Hello—Old Bo." Pan Shi answered the phone briskly, and her smile froze after listening to the other person's words, "Where did you fall?"

Bai Zhou raised his head suddenly and stared at her.

"Which hospital...Okay, I'll go there now."

Pan Shi got up in a hurry with an ugly expression, and Bai Zhouyi also stood up, and asked in a deep voice, "What's wrong?"

"Your dad slipped in the company. I don't know why he fell and couldn't get up. Now he is in the hospital."

Bai Zhou picked up the phone: "Which hospital, I will call a taxi."

Pan Shi told him.

As soon as Bai Zhou called a car with the software, he reminded Pan Shi who was about to go out: "Coat, don't be caught by the wind."

The older you get, the more you can't bear to fall. Although Bai's father is not "old", his body can't bear the hard fall after working overtime and staying up all year round. When he fell down, he only felt back pain, but he soon found that he could not stand Woke up.

When Bai Zhouyi and Pan Shi rushed to the hospital, Father Bai had already done a preliminary examination.

"In this case, there are two solutions. Conservative treatment uses massage and moxibustion. The patient can take a good rest for a period of time to delay the nerve strain." The doctor looked at the examination results and said to the two.

"Can it be completely cured?" Pan Shi asked.

"The probability is not high, it mainly depends on the patient's own condition."

Pan Shi whispered a word of thanks, and fell silent.

Bai Zhou took over the conversation and asked, "What about another method?"

"Another method requires surgery. A small incision is made at the position of the tailbone for minimally invasive surgery. The risk of this operation is relatively small. If the recovery is good, you can live normally two months after the operation... "

"What if the operation fails?"

"There could be a risk of paralysis."

The doctor suggested an operation, and after discussing with Bai's father and agreeing, Pan Shi paid the fee.Father Bai fell and wiped a large piece of skin off his waist, which happened to be where the surgery was going to be performed. To be on the safe side, the doctor decided to perform the operation after the wound healed. During this time, Father Bai was hospitalized to rest.

Pan Shi was worried and wanted to accompany her in the bed, but neither Bai's father nor Bai Zhouyi agreed. She was weak and would get sick easily if she didn't rest well.Father Bai lay on the bed and told them all to go back, and he could do it by himself.

But Bai Zhouyi stayed in the end, because Father Bai couldn't stand up, and someone had to help him to the bathroom.

In the evening, after Bai Zhou wiped Father Bai's body and took him to the bathroom, he sat down on the bench by the door.The beds in the hospital are tight, and he does not have a companion bed configuration for the time being.

Bai Zhou didn't feel tired until he sat down. He didn't have much experience in taking care of people. In the past, he could only help Lan Shan blow his hair and wash his clothes, but now he has to accompany the patient with limited mobility.

Father Bai was very quiet in the ward, probably fell asleep. Bai Zhouyi waited for a long time before he took out the phone dully, moved his fingers aimlessly, and operated it without thinking.

It wasn't until the call page appeared on the screen that Bai Zhouyi realized that he had dialed Lanshan unconsciously.He waited for a while, but no one answered on that side.Bai Zhou rubbed his face helplessly when he saw the notification that the call failed, and then realized that there was a jet lag in Paris. At this point, Lanshan was still training, and he was really anxious.

He opened the chat history with Lan Shan again. The two were still in the cold war period, and there was an endless stream of messages in the chat box.As soon as Bai Zhou sat in the darkness, he looked around, and Lan Shan's lively remarks slightly suppressed his restless mood.He turned to the bottom, sent a sighing emoji, and quickly sent it again, I miss you.

He didn't think much about it when he sent it out, but the sentence of "missing you" seemed to open the gate of catharsis. Exhaustion and longing rushed down, and Bai Zhouyi was almost crushed by the surging emotions. He missed Lanshan all the time, but never There was a moment so intense.

His straight waist was slightly relaxed, his elbows rested on his knees, and his head was buried in his palms.

Bai Zhouyi sat like this for a long time, during which Father Bai woke up a few times in pain, he went in and helped him turn over a few times to make him sleep more comfortably, and then came out and sat down on the bench.

After coming down three or four times, Bai Zhouyi was even more tired. He sat at the door exhaustedly, his back was not strong enough to straighten up, and someone was coming from far away in the corridor, but he didn't notice.

"Bai Zhouyi!" Until Lan Shan hurriedly stood in front of him, wearing a heavy down jacket that had nothing to do with southern cities, he grabbed Bai Zhouyi and said anxiously, "Where is godfather? Godfather is okay."

Bai Zhou raised his head as if he didn't know him, remained motionless for a while, and said after a few seconds: "He's fine, he's asleep."

"That's good." Lan Shan heaved a sigh of relief, then raised his hand, touched the thick dark circles under his eyelids distressedly, and said, "Are you okay..."

Before he finished speaking, Bai Zhou reached out and grabbed the edge of his down jacket, and slowly buried his head in his arms.
