After Chen Xiaoyang's brain was knocked, he had a faint pain for three days, and he also got a big bag, after his grandmother used hot water to reduce his swelling, he applied safflower oil, and the external injury was almost healed, but it left internal injuries, the hippocampus of the cerebral cortex was impacted, his memory and learning ability were affected, his reaction began to become sluggish, his memory began to decline, but his logical thinking ability became stronger.

No one knew that all this change was due to the blow that Grandpa struck on his head.

Chen Xiaoyang was doing a mathematical thinking problem about distance and time on his winter vacation homework, after he read the problem, it took less than two minutes to find the solution idea, but when he calculated the 24+17 equation, he picked up the draft and counted his fingers, and calculated the result as 31, he felt incredible, and it took 30 minutes to calculate the correct result for a question.

Chen Xiaoyang's Chinese pinyin writing has also been affected every time, and the pinyin questions for his winter vacation homework are now filled in according to the Chinese language.

After that, his Chinese pinyin and mathematical calculations seemed to have become his eternal obstacles, and no matter how hard he tried, he couldn't get over.

Before I knew it, the New Year was over, and my parents still didn't come back after the New Year, but just called him and said, "Son, Mom and Dad are too busy, and they have to earn you tuition and living expenses, you must study hard, and you will have a good future in the future." There were no other words.

After the Chinese New Year, the school will start, and when families begin to send their ancestors to the school for renovation, the school will also begin to become laughter. But there are two exceptions.

"Meihan, where is the tiger grenade? , why didn't you come to school" After class, Chen Xiaoyang saw that the tiger grenade was not there, so he asked Meihan.

"I don't know about her either"

"You have such a good relationship with her, didn't she tell you?"

"Oh, by the way, brother, she came to me before school started, and gave me a letter, saying that I would hand it over to you when school started, and she ran away in a hurry after she finished speaking."

After Meihan finished speaking, she took out a letter from her schoolbag and gave it to Chen Xiaoyang.

Chen Xiaoyang took the letter, and a small locust tree was painted on the cover of the envelope.

Chen Xiaoyang opened the letter, "To my best friend Chen Xiaoyang, from the first time I saw you, I knew that you were my best friend in this life, you left a deep trace on my books, but also left a deep trace in my heart, in the past five years, the three of us have relied on each other, know each other, and left the most beautiful laughter under the ancient locust tree." Thank you for enduring the scolding of your family in order to help me get angry, you are the most handsome person in my heart, and thank you Meihan my best friend, because you gave me the happiest childhood, and finally I want to tell you a bad news, I am going to go to school with my parents in other places, they are afraid that my grandparents will not take good care of me when they are old, I will ask me to go over, I can't refuse, we can't see each other for a long time, I promise you that you will come back to see you every New Year, you must be happy and happy, and finally I want to say to you, I like you Chen Xiaoyang, and I love your girlfriend too. ”

After reading this letter, Chen Xiaoyang and Meihan were a little lost, the relationship between the three of them in the past five years was the best in the class, and now that the tiger grenade is gone, the two of them seem to be missing something.

The brother and sister sat under the ancient locust tree, silent, reminiscing about the time the three of them spent together.

"Brother, the tiger grenade is interesting to you," Meihan took the lead in breaking the silence.

"What's interesting, what are you thinking about in your little brain!" Chen Xiaoyang said as if he didn't understand anything.

"Hey, it seems to be just wishful thinking on the part of the tiger grenade!" Mihan sighed.
