After chatting with Zhang Keke, Zhao ChuChu went to his bunk, lay in bed, looked absently at his books, but looked at Feng Qiming lying in the lower bunk opposite from time to time.

More than two hours have passed, and Feng Qiming still doesn't wake up.

Zhao ChuChu was really worried. After hesitating for a moment, he couldn't help asking Su Su on the opposite berth, "Miss Su, didn't you say that Mr. Feng would wake up in half an hour? Why is he still not awake? "

Su Su obviously didn't expect Zhao ChuChu to ask her such a question. She was stunned for a moment and replied, "maybe the boss was just tired, so maybe he went to sleep." After saying that, seeing Zhao ChuChu's eyebrows do not show, he added, "don't worry, Miss Zhao, that tranquilizer is very safe and won't hurt your body."

Zhao ChuChu nodded slightly, didn't speak, took back his eyes and continued to fall on the page.

As time went by, towards the evening, Zhao ChuChu couldn't stand the oppressive atmosphere after all. He got out of bed and was ready to go out for a walk.

"Coco, let's go to the corridor and get some air." Zhao ChuChu proposed.

Zhang Keke readily agreed, "OK, this bed is too hard. I'm worried about backache. I'll have a good time walking." With that, Zhang Keke took his coat and followed Zhao ChuChu out of the box.

There was a cool wind blowing in the corridor. Zhao ChuChu felt refreshed instantly. The more sober his mind was, the more worried he was about a series of problems.

Zhang Keke seemed to see Zhang ChuChu's thoughts and comforted him: "ChuChu, as long as we get off after tonight and tomorrow morning, don't think too much. If we don't behave well, let him go."

"But everything I found today is too strange." Zhao ChuChu said as if talking to himself. His eyes fell out of the window, looking at the fast retreating plants and trees, and frowned slightly.

When Zhang Keke was about to speak, he suddenly heard a child's cry. The cry came suddenly, like a knife cutting through the air. It was terrible. Zhang Keke couldn't help but tremble.

"What's the matter?" Zhang Keke's eyebrows were tight when he spoke. "I didn't hear the cry of a child from getting on the bus to just now. Why did such a sad cry suddenly come?"

Zhao ChuChu was also frightened and instinctively grabbed Zhang Keke's hand. "The child's cry seems to come from the box on the right. Let's go and have a look."

"OK, let's go." Zhang Keke nodded.

They hurried to the box and saw the door crowded with people from a distance. It seems that the child's cry surprised other passengers.

Zhao ChuChu and Zhang Keke couldn't squeeze in, so they had to stand outside the crowd and look inside. The crying child was held by a young woman, and the woman kept coaxing, "the baby is good, the mother is here, not afraid..."

The young man sitting next to him seemed to be the father of the child. He was talking to other passengers. Zhao ChuChu leaned his ears and listened carefully to what they said.

"Although my children are only three years old, they are very quiet on weekdays. They don't cry or make noise. You know, since we got on the bus in the morning, my babies are very obedient and bought just now. I don't know why they suddenly cry. They cry very fiercely, as if they were grabbed by meat."

The middle-aged woman opposite the child's father nodded and echoed, "yes, I got on the bus with three of your family. Your child has always been quiet. I was startled by the sudden cry just now. The cry is so sad. I'm not hungry."

"I can't be hungry." The child's father frowned and shook his head. "My baby has always had a good appetite. When the dining car was pushed over half an hour ago, I bought him a box lunch and ate most of it. Later, I ate fruit and drank milk. How can I be hungry?"

The middle-aged man nearby said, "is the child sick? Why did you cry when you were uncomfortable? "

"My wife and I thought so, so we asked the baby for the first time, but she shook her head. I think it shouldn't be uncomfortable." The child's father paused and continued, "besides, my baby has always been in good health and rarely gets sick."

The middle-aged man sighed, "is that strange? Was he frightened by something? "

"I thought I was scared." The child's father said seriously, "just now my wife and I were sleeping. The baby was sitting at the head of the bed. I think which passenger frightened him."

Hearing this, Zhao ChuChu looked back at Zhang Keke and hesitated for a moment before whispering, "Keke, will this matter have something to do with the morning?"

Zhang Keke pulled ChuChu aside and whispered, "ChuChu, in the morning, Mr. Feng and the middle-aged man in the box next door suddenly went crazy. It is likely that there was something wrong with the box lunch. Just now the child's father said that the child ate the box lunch half an hour ago, so..."

"You also think there is something wrong with the lunch box in the car?" Zhao ChuChu frowned deeply.

Zhang Keke nodded. "Clearly, do you remember the steward named Xiao Liu? At noon, he seemed to be ill. I think there is probably something wrong with the boxed lunch in the car." Zhang Keke sighed and continued, "but this is just our guess. Without evidence, we can't solve this matter at all."

Zhang Keke's words are not unreasonable. Zhao ChuChu thought for a while before opening his mouth, "Keke, let's go back first. Mr. Feng should have woken up by this time. Let's confirm with him."

"OK, let's go." Zhang Keke nodded and turned around to see Lu Xingdao coming this way. "Clearly, Lu Xingdao is coming."

Zhao ChuChu looked up and saw Lu Xingdao's eyebrows slightly. He guessed that Lu Xingdao should have gone to the box. He didn't find her. He was worried. Zhao ChuChu stepped up quickly.

"Orbit."

Lu Xingdao saw Zhao ChuChu and hugged Zhao ChuChu in his arms without saying a word. Yes, he was really worried. Just now he saw the empty berths of Zhao ChuChu and Zhang Keke in the box, Lu Xingdao was worried.

So many strange things happened that he had to worry.

After a while, Lu Xingdao let go of Zhao ChuChu. "Why don't you stay in the box?"

"After lying in the bunk all afternoon, I felt a little stuffy, so I went out with cocoa to get some air." Zhao ChuChu patiently explained and smiled faintly, "I'm sorry to worry you."

Lu Xingdao sighed slightly, "I'm too nervous, but what happened just now is really scary. Although it's artificial, the people in half the carriage are terrified, so I'm worried about you two."

"What happened?"

"What happened?"
