The book-crossing case happened! The villains all want me to go to jail

One afternoon, the sun was blazing, and Xie Xuan arrived early at the gate of Xie Ran's school to wait. The school bell rang, and students poured out of the school like a tide. Xie Ran's tall and thin figure appeared in the crowd, his ears slightly red from the heat, and his eyes were indifferent.

Xie Xuan'an walked up quickly, with a flattering smile on his face, handed over the beautifully packaged book with both hands, and said, "Xiao Ran, I heard that you like photography, so I bought this book for you." Xie Ran was slightly stunned, hesitated for a moment, but still reached out to take the book, muttering softly, "You still have some conscience."

Xie Xuan'an struck while the iron was hot, his eyes full of anticipation: "Xiao Ran, how about we go to the suburbs to take photos together on the weekend?" Xie Ran raised his head, his eyes somewhat evasive, and was silent for a long time.

Xie Xuanan quickly added: "I know a very beautiful place, I guarantee you will be able to take satisfactory photos." Xie Ran pursed his lips and finally nodded, "Okay, I'll give you credit for your sincerity."

On the weekend, the two brothers came to the suburbs carrying heavy photographic equipment. Along the way, Xie Xuan was carefully looking for topics to communicate with Xie Ran. Although Xie Ran didn't respond much, the atmosphere was not that awkward.

When they arrived at their destination, the picturesque natural scenery in front of them was fascinating. Xie Xuan took the initiative to help Xie Ran with the equipment, and his eyes kept looking for the best shooting angle.

During the filming process, Xie Xuan'an stood behind Xie Ran. Looking at his brother's serious look, he couldn't help but praise him: "Xiao Ran, your shooting skills are getting better and better!" As he said that, he gently patted Xie Ran on the shoulder.

Xie Ran's mouth corners slightly raised, with a hint of pride in his eyes: "Of course!"

Suddenly, the lens cap of Xie Ran's camera accidentally rolled down a steep hill. Xie Xuan rushed over without hesitation, slipped, and fell to the ground, with a large scratch on his arm.

Xie Ran was horrified and ran over to help him up, his eyes full of concern: "Brother, are you okay?" As he spoke, he gently brushed the dust off Xie Xuan'an's body with his hand.

Xie Xuan'an endured the pain and said with a smile: "It's okay, as long as I can help you pick up the lens cap, this little injury is nothing."

At that moment, Xie Ran's eyes revealed a long-lost concern and emotion.

In the evening, the afterglow of the setting sun sprinkled on them like a golden veil. Xie Ran lowered his head, rubbed the ground with his toes, and whispered: "Brother, I actually want to make peace with you, but..."

Xie Xuan'an put his arm around Xie Ran's shoulders and interrupted him: "Xiao Ran, the past is in the past, let's be fine together in the future."

At that moment, it seemed as if a piece of ice began to melt in the hearts of the two brothers. They knew that the road ahead was still long, but as long as they treated each other sincerely, the bond of family affection would never be broken.

They reconciled and successfully moved back into the same house.

The bell of winter vacation rang, and Xie Ran reluctantly moved in with his brother Xie Xuan. Thinking of his brother's chilling indifference when his mother was seriously ill last time, Xie Ran's heart was like covered by a thick layer of frost, and he was full of reluctance and resistance to his brother.

Snow fluttered down, covering the world with a layer of white. In the early morning, before it was completely bright, Xie Xuan walked into the kitchen quietly. His tall figure was busy in the kitchen. The morning light shone through the window on his well-defined face. His high nose bridge and his deep and bright eyes were like twinkling stars in the night sky. His thick eyebrows were slightly raised, adding a bit of heroism. His short black hair was neat and tidy, exuding the vitality of youth. Xie Xuan prepared breakfast seriously, his eyes focused and gentle.

"Xiaoran, get up and have breakfast, otherwise it will get cold." Xie Xuan'an's gentle voice reached Xie Ran's room, with a bit of caution.

Xie Ran pulled the quilt up, covered his head, and pretended not to hear. He muttered to himself, "Humph, it's too late to show your affection now!"

However, hunger eventually triumphed over stubbornness. Xie Ran lingered over and came to the dining table. Seeing the steaming millet porridge, golden and crispy fried dough sticks, and carefully prepared side dishes on the table, his brother's expectant and slightly nervous eyes made him slightly stunned. His heart trembled unconsciously, but he didn't want to admit it, so he quickly turned his head away and sat down to eat without saying a word.

One night, the lights in the room seemed a little dim. Xie Ran sat at his desk, frowning, scratching his head at a difficult math problem for senior high school students. This was a question about the comprehensive application of functions and derivatives: Given a function , if there exists , such that , find the value of .

Xie Xuanan gently opened the door, and seeing his brother's distressed look, the corners of his mouth slightly raised, he walked to Xie Ran's side, and said softly: "Xiao Ran, don't worry, brother will help you."

Xie Ran ignored it at first, threw down his pen and turned away.

Xie Xuanan didn't care. He patiently picked up the pen and wrote on the draft paper: "First, we take the derivative of the function , . Because there exists , so that , so we let , that is . This is a quadratic equation, we can use the root-finding formula , where , , .

First calculate the discriminant .

Because , the equation has two different real roots.

.

Because , so . "

While Xie Xuan'an was explaining, he observed Xie Ran's reaction.

Xie Ran secretly glanced at his brother and saw that he was focused, his eyes were firm and confident, and beads of sweat appeared on his forehead because of thinking. Somehow, Xie Ran's resistance gradually dissipated and he began to listen seriously.

Finally, Xie Ran suddenly understood and a happy smile appeared on his face. Xie Xuanan patted him on the shoulder gently, "It's good that you understand. Don't worry when you encounter difficulties in the future."

One day, Xie Ran accidentally fell in the snow and caught a cold. He lay in bed, pale and weak.

After Xie Xuanan learned about it, he hurriedly put down what he was doing, touched Xie Ran's forehead with his hand to see if he had a fever, and then hurried to the kitchen to boil ginger soup. He walked into the room with the ginger soup, sat by the bed, and coaxed Xie Ran softly: "Xiao Ran, come, drink the ginger soup, you will get better faster."

Xie Ran looked at his brother's concerned eyes, and felt a little touched, but he still turned his head away unwillingly, "I don't want to drink it, it's too hard to drink."

Xie Xuanan smiled helplessly, "Be good, drink it so you can get better quickly. Brother has prepared some candy for you, you can eat it after you drink it."

With his brother's patient persuasion, Xie Ran finally drank the ginger soup.

On the weekend, the snow outside stopped, and the sky and the earth were covered with silver. Xie Xuanan looked at the beautiful scenery outside the window and suggested: "Xiao Ran, how about we go out and make a snowman?"

Xie Ran wanted to refuse, but looking at his brother's expectant eyes, he hesitated for a moment and nodded reluctantly.

When they arrived at the snow, Xie Xuan'an rolled snowballs with great interest, and occasionally threw some snow at Xie Ran. His gentle face was even more charming against the backdrop of the white snow, and his smile was as warm and bright as the sun in winter. Xie Ran was irritated and began to fight back, and the two laughed and played in the snow.

When Xie Xuan'an was making a snowman, his hands were frozen red, but he was still concentrating on shaping the snowman. Seeing this, Xie Ran felt a little sorry and helped silently.

After a while, a cute snowman was built. Xie Xuan looked at the snowman, then looked at Xie Ran, and smiled happily.

One night, Xie Ran was awakened by a nightmare and couldn't fall asleep. He walked into the living room and found Xie Xuan sitting on the sofa, holding a family photo in his hand, his eyes full of guilt and longing.

Xie Xuan'an's handsome profile looked particularly deep in the moonlight. He gently stroked the photo and murmured to himself: "Mom, I know I was wrong. I will definitely take good care of Xiaoran."

Xie Ran stood there quietly, looking at his brother. Hearing his brother's words, the ice in his heart melted a little.

At the end of the winter vacation, Xie Xuan'an took Xie Ran to the park he often visited when he was a child. The lake in the park had frozen over, and the branches were covered with crystal icicles.

Xie Xuanan took out a carefully packed box from his backpack and handed it to Xie Ran, "Xiao Ran, this is for you."

Xie Ran opened the box puzzled and found the photo album he had always wanted inside.

Xie Xuan'an looked at his brother's surprised expression and said, "Xiao Ran, I was wrong before. I will take good care of you in the future and will not let you suffer any grievances again."

Xie Ran's eyes were moist. He raised his head and looked at his handsome and sincere brother. "Brother, I am also wrong. I shouldn't have ignored you all this time."

This winter vacation, with his brother's care and efforts, Xie Ran's resentment gradually dissipated, and the warmth of family affection melted the ice in his heart like a spring breeze.
