The basic engineering course was completed quickly, but what shocked Zhang Chengyuan was the English class. When the homeroom teacher and English teacher of the first class walked into the classroom of the second class, when Zhang Chengyuan saw the face of the English teacher, his surprised expression froze for a long time. This English teacher Zhang Chengyuan is not unfamiliar, and can even be said to be very familiar. This English teacher's name is Wang Yumei, her good brother, the mother of her good neighbor Leng Changhe, and the kind and kind Aunt Wang she has known since she was a child.

But for a long time, Zhang Chengyuan thought that Aunt Wang was a teacher at Lanqi University, but now standing in the second class classroom of Qihang School is clearly Leng Changhe's mother Wang Yumei.

Why didn't she tell me before that she was a teacher at the Voyage School?

"Since Aunt Wang is the homeroom teacher, I have such a good relationship with Leng Changhe, why do you ...... when you are assigned to a class? Is it ...... to be separated?"

The words Ruan Xiyue said to herself last night echoed in Zhang Chengyuan's ears again.

"Xiyue, we're together, then, what about the cold long river?"

“…… So, do you want me to be with him? ”

"Don't want to ......"

"The two of us were naturally together, he ...... Emotional matters, barely come. ”

"But...... Shigetsu, he's my best brother, and besides, he used to mistake me for annoying you. Once he asked me if I hated you, and he said that he liked you very much, so let me see that it is not difficult for you in his face. I didn't tell him the truth at the time, I didn't say that I liked you too, and I promised to help him. And now, I'm with you, Changhe must feel that he has been deceived, I, I can't bear to ......"

"When?!"

"What, when?"

"When did he think you hated me?"

"Freshman of high school, you just came to our class."

“……”

"So I think that when we are together, I am very sorry for Leng Changhe."

"You're so naïve...... You don't have to worry about it. ”

"What?"

"He, when he was a freshman in high school, observed that it didn't seem normal between the two of us, and he asked me in private if I liked you? He deliberately asked if you hated me, and deliberately made you think that he thought you hated me, so that it would not be considered to be robbing you of the girl you like. Cheng Yuan, you don't need to be so guilty. ”

"No way, we're the best brothers."

"However, I have always heard that when two people like one person at the same time, no matter how good a brother is, there will never be friendship anymore."

"I don't believe it, let's not discuss this, okay......"

……

Suddenly, Zhang Chengyuan seemed to understand why he was assigned to the second shift, and suddenly, his guilt towards Leng Changhe also decreased.

Zhang Chengyuan didn't listen to the whole English class at all, he was re-examining his relationship with Leng Changhe, it came too suddenly, he couldn't accept it for a while, and he didn't want to believe that Leng Changhe knew that he also liked Ruan Xiyue, and deliberately pretended not to know, to earn ...... with him

"Cheng Yuan, let's go eat!"

Until the bell rang at the end of class, the classmates walked out of the classroom, and Sun Wanyang called Zhang Chengyuan to eat together.

Zhang Chengyuan nodded, and the two walked towards the cafeteria.

Today, at noon, there are exquisite pork rib noodles in the canteen, the noodles have a chewy taste, the pork ribs are delicious, and the soup is rich, and everyone eats with relish.

"I felt like you were staring at the teacher in class just now, what do you think?" Sun Wanyang asked while eating.

Zhang Chengyuan hesitated, swallowed a piece of pork ribs in his mouth, nodded and said, "To tell you the truth, she is my neighbor, but I didn't know until today that she worked at Qihang School!" And her son, who is also my good brother, is now in the first class. I have a lot of buddies in the first shift, but I am the only one who has been assigned to the second shift. ”

"That's it! No wonder you feel preoccupied. If you want to start a little bit, you will be assigned to the second class, so that you will have the opportunity to meet more new friends! Sun Wanyang said with a sunny smile.

"Yes!" Zhang Chengyuan nodded, patted Sun Wanyang on the shoulder and said, "You are the first good brother I have met since I came to the second class!" ”

Both of them ate all the noodles and drank all the soup by the way. Zhang Chengyuan habitually poured out two pills from his pocket and swallowed them.

Sun Wanyang frowned when he saw him taking medicine, and stopped talking.

"You didn't bring any medicine?" Zhang Chengyuan noticed Sun Wanyang's expression and handed over his medicine bottle, "Eat mine!" ”

Sun Wanyang shook his head, hesitated for a moment, and then said to Zhang Chengyuan: "Dude, my family is from a pharmaceutical factory, so I know a little bit about pharmacology. ”

Zhang Chengyuan was listening.

"This, trace element tablets, is actually not necessary to eat. As long as we pay attention to a reasonable diet, in fact, we do not need to supplement trace elements. Sun Wanyang seemed to be saying very seriously.

Zhang Chengyuan nodded slowly. He was hesitating. Out of kindness, Zhang Chengyuan wanted to tell him the true effect of the medicine, but he didn't dare to say it. Once this news spreads, it will be very unfavorable to Wei Hengyi. But if he didn't say it, he wouldn't be honest with Sun Wanyang.

"There is some truth in what you said, but since the medicine is uniformly distributed to our students, since everyone is taking it, there must be a reason to take it. There's no harm in not eating it, we don't know, but there's no harm in eating it, right? Zhang Chengyuan didn't dare to tell the truth, but he still tried his best to persuade Sun Wanyang to take medicine.

Sun Wanyang shook his head helplessly and said: "The so-called medicine is three points poison, and the pharmacology is the same as fighting a war, with eight hundred self-losses and one thousand enemy injuries. Although general drugs can play a therapeutic role, they can also damage one's own vitality. To take the simplest example, most Chinese herbs are taken for a long time, which is a great load on the kidneys. ”

"But trace element tablets are health care drugs, and they can't be compared with therapeutic drugs!" Zhang Chengyuan said.

Both of them stopped talking, and before they knew it, they both raised their voices, attracting the attention of the classmates around them.

"Zhang Chengyuan!"

The two turned their heads to look, and Principal Yu suddenly came to the two of them at some point, and looked at Zhang Chengyuan curiously with a pair of eyes.

"Hello Principal Yu, is there anything wrong with me?" Zhang Chengyuan was slightly surprised.

"Come to my office." Principal Yu's tone was calm.

Zhang Chengyuan didn't know why, so he said hello to Sun Wanyang and left with Principal Yu.

"You don't have to be nervous, I'll talk to you casually." When he came to the principal's office, Principal Yu said kindly, "Don't be restrained, sit down!" ”

Zhang Chengyuan sat on the sofa obediently, but he was still very worried in his heart, and he was thinking about the reason why Principal Yu was looking for him.

"What did your parents do?" Principal Yu asked calmly.

"My parents are both teachers at Lanqi University." Zhang Chengyuan couldn't hide the pride in his heart.

"Are you still used to coming to school?"

"Habit, everything is fine here."

"Some students, after coming to the school, may be a little uncomfortable, so I immediately asked a few students to investigate. If you or any of your classmates are feeling unwell, please let me know in time. ”

"Thank you Principal Yu for your concern!" Zhang Chengyuan felt a warmth in his heart.

"Do you want to live in the Pure Land?"

"Yes! Absolutely! ”

"Then work hard and don't let yourself regret it. Well, so be it. There is a boy named Cambridge Liu in your class, do you know him? ”

"I don't know." Zhang Chengyuan replied from afar. On the second day of school, most of the thirty people in the class he didn't know yet.

"Then, what about Zhang Luoqi?"

"Zhang Luoqi, I know."

"Let's go, let Zhang Luoqi come to my office to find me." Principal Yu said kindly.

Zhang Chengyuan respectfully said goodbye to President Yu and left.

Principal Yu lit a cigarette and picked up a stack of specially marked medical examination reports on his desk. There are seven copies in total, and the first one is Zhang Chengyuan's.

Principal Yu drew a check mark on Zhang Chengyuan's physical examination report, threw it aside, and flipped through several other physical examination reports.

"Liu Cambridge, Zhang Luoqi, Chen Jiatong, Zhu Tiancao, Leng Changhe, Ruan Xiyue." Principal Yu glanced at the names of the owners of several physical examination reports, took a deep puff of cigarette, and then slowly pulled out Chen Jiatong's physical examination report, looked through it, spit out the smoke ring, and silently tore off her physical examination report.

Next, President Yu had similar one-on-one conversations with Zhang Luoqi, Liu Cambridge, Zhu Tiancao, and Leng Changhe. Several students went in with great curiosity and came out in a daze. Especially Leng Changhe, the fact that his mother is his homeroom teacher was enough to shock him, and the conversation with Principal Yu made him even more confused.

Before Leng Changhe left, Principal Yu asked him to call Ruan Xiyue over.

While waiting, Principal Yu casually flipped through Ruan Xiyue's physical examination report. Judging from the photo, it was a sunny and beautiful little girl, and Principal Yu had a kind smile on her face. Just as he wanted to put down Ruan Xiyue's physical examination report, a few sensitive words caught his eye.

These words seemed to have a powerful deterrent effect, which made Principal Yu couldn't help but take a long breath of excitement, and even the hand holding the physical examination report was trembling.

In the blood type column of Ruan Xiyue's physical examination report, it is clearly printed in bold font - RH Yin AB type.

RH Yin AB type, the legendary panda blood. This blood type is quite rare in the population. Yu Tao looked at this blood type, his breathing became heavier and heavier, and his emotions seemed to be excited.

A soft knock on the door interrupted Principal Yu's thoughts.

"Please come in!" Principal Yu replied, hurriedly lighting another cigarette.

The door opened, and it was Ruan Xiyue who entered.

Principal Yu looked at the girl in front of him, and there was a bit of kindness, joy, and sadness in his eyes.

"Principal Yu ......" Ruan Xiyue broke the silence.

"Ruan Xiyue, right? You may be seated. Principal Yu's voice was as plain as possible, and his eyes were quite kind, "I came to you, just to talk casually, you don't have to be nervous." ”

"En" Ruan Xiyue replied and sat on the sofa.

"What do you, Mom and Dad do?" Principal Yu asked with a smile.

"President Yu, my father is the president of Lanqi University, and my mother is a nurse at the university hospital." Ruan Xiyue replied.

Although her father also has a high status in Lan Qicheng, she is not proud of her father because her father once broke up her and Zhang Chengyuan.

"How's Mom and Dad?" Principal Yu continued to ask.

"Thank you for your concern, my parents are in good health." Ruan Xiyue also relaxed when she saw Principal Yu chatting about family life.

"Just be in good health!" Principal Yu smiled kindly, "Will you be homesick when you come to Qihang School?" ”

"It's okay, I miss my mother a little." Ruan Xiyue said.

"Good boy!" Principal Yu nodded and said, "If you are homesick, you can talk to the psychology teacher, and if you are in trouble, you can come to me." ”

"Thank you, Principal Yu, for your concern." Ruan Xiyue replied with a smile.

"Do you have any hobbies?" Principal Yu asked.

"I love swimming, dancing, running...... There are also engravings. Ruan Xiyue replied.

"Engraving...... Ah, and a lot of talent. I didn't have anything else to do with you today, but I just started school, and I interviewed a few classmates randomly to see if I was suitable for life here, and it seems that you have adapted well. "Yu Tao is as kind as a father.

"Scared the hell out of me!" Ruan Xiyue breathed a sigh of relief and said, "I thought I had made some mistake!" ”

"You have to work hard! You can't always think about getting by without making mistakes. Okay, it's okay, you can rest early! ”

Ruan Xiyue happily said goodbye and left.

Principal Yu looked at the photo on Ruan Xiyue's physical examination report and was silent for a long time.

…………

At night, Zhang Chengyuan and Ruan Xiyue are happily together, and this sweetness of first love may be the most unforgettable time in a person's life. The moonlight sheds a little bit of light, sending blessings to them.

Sun Pengcheng stood dozens of meters away from the tree, holding a steel ruler in his hand, fascinated by one eye.

"What are you doing?" Wu Hao asked puzzled.

"Surveying and mapping."

"Huh?"

"Look how tall these trees are."

"Do you need quantitative calculations? What's the point? ”

"Meaningful!"

Sun Pengcheng put down the steel ruler in his hand, closed his eyes, and said after a silent calculation in his heart: "The average altitude of these redwood trees is twenty-eight meters high, and the height of the main trunk is calculated according to twenty meters, and the diameter is conservative, according to 800mm, I checked it in the library, and the density of redwoods is about 0.7g/mm3, so that a redwood tree has at least 7 tons of weight in the trunk alone." Counting the roots and branches, a tree weighs more than ten tons. ”

"What are you doing researching this?"

"Instructor Lu said that the trees were all transported by air, and I was thinking about how to transport them. Looking at the carrying specifications of Chinese transport aircraft before the end of the world, there are only a few dozen of them that can complete such a job. Look at the fact that there are so many redwoods on campus, and there are several schools like the Sailing School in the country, how many trees have to be transported, and what a huge project this is! ”

Wu Hao listened to Sun Pengcheng's analysis, and unconsciously felt a chill welling up in his heart.

"So I think that the country transplanted these sequoia trees at a huge cost, there must be other meanings, Wu Hao, you have a smart brain, help me think about it!"

“…… You're so bored, I'm not interested in thinking about that. ”
