"Brother." Yan Bubu shouted.
Feng Chen had already walked to the door of the classroom. When he heard the voice, he stopped, turned to look at him, and a smile appeared on his face.
"Hehe." Yan Bubu was held by the soldier and smiled at him. Then he suddenly frowned and said, "Go back to your classroom."
Yan Bubu watched Feng Chen enter the large classroom with eager eyes, then returned to his own classroom in disappointment.
The soldiers carried the food into three classrooms. After breakfast, the three classes of large, medium and small started classes.
The students in Feng Chen's large class are all about the same age as him. They have all experienced several disasters or the death of relatives and friends, and their personalities have more or less settled down. They don't talk to each other, but just eat quietly, wait quietly in their seats for the teacher, and listen quietly to the students in the small class next door singing.
"The puppy woofs, the duck quacks, the lamb bleats, the rain gurgles..."
Feng Chen found a dried ballpoint pen from the table and turned it rapidly between his fingers while trying to identify Yan Bubu's voice in the song.
Yan Bubu's singing was always out of tune and his voice was loud. Feng Chen quickly recognized his voice and also heard that the children were being led by him to sing out of tune.
"Stop, stop, stop, start again, sing along with the teacher..."
When Yu Yuan entered the classroom, she saw Feng Chen at a glance and saw the happy smile on his face.
"Okay, no matter what you're happy about, calm down and get ready for class." Yu Yuan walked to the desk, unbuttoned the top button of his military uniform, and rolled up his sleeves. "My name is Yu Yuan. I believe you all know me. I'm Colonel Yu of the Western Alliance."
Yu Yuan rolled up his sleeves and glanced across the faces of these half-grown children. "I am standing here now. I am not only Colonel Yu, but also your teacher. I will be teaching your first lesson, and the content of this lesson is called how to survive."
Yu Yuan talked about very practical things, such as how to take shelter effectively when encountering sudden incidents, how to rescue dying people, how to bandage your own wounds, etc.
Although Feng Chen knew this knowledge, he listened very carefully because what Yu Yuan said was very different from what was in the book or what the instructors at the training camp said.
He removed some written content and some unnecessary procedures, which seemed to be inconsistent with the process and rules, but was more practical.
Halfway through the class, the kids from the small class next door started queuing up to go to the toilet. When they passed by the door of the big class, they all poked their heads in and called out "brother or sister" in surprise from time to time.
Feng Chen had been looking ahead, but now he turned and looked towards the door.
The children's chattering was too loud, so Yu Yuan stopped teaching. He didn't close the door. He just supported the desk with both hands and looked at them with a smile.
Yan Bubu was in the middle of the team. When he walked to the gate hand in hand with a little boy, he naturally saw Yu Yuan first and waved to him.
Yu Yuan smiled and nodded, and waved slightly at Yan Bubu with her left hand hanging behind the table.
Yan Bubu continued to look around the classroom, but when he saw Feng Chen sitting next to the bed, he immediately wanted to shout to him, but Teacher Yu said at this time: "Students, please don't make any noise. It will disturb the older brothers and sisters in class."
