I saw that the line was already long, and Xiao Zhen could hardly see the head of the team.

The entire canteen on the first floor also looked gloomy against the backdrop of the crowd.

"Wow, there are so many people, when will they be in line to eat? Xiao Zhen looked at the long queue that had already lined up at the door of the cafeteria and said.

"Haha, don't worry, isn't there a staircase going up here? Anyway, there are so many people in front, why don't you go to the second floor and have a look." Lao Wu looked at the stairs pointed by the arrow on the left and said.

So, Xiao Zhen followed Lao Wu to the second floor.

Sure enough, the cafeteria on the second floor was almost empty, and the staff of several canteens seemed very relaxed and happy.

Staff A: "Why do you say it's so easy today, the supervisor also said that there may be a lot of people eating today, but only more than 20 people came after this order." ”

Staff member B: "Yes, in normal times, this chicken leg set has already been snatched up, but what is the situation today, no one has come to prepare such a good dish." ”

So, Xiao Zhen and Lao Wu immediately walked to the place where they were eating, showed their Chinese food coupons, and began to eat.

"It doesn't seem that there will be more people today, so let's give you more, it's a waste if no one eats anyway. Saying that, staff A gave Xiao Zhen two chicken legs.

Lao Wu and Xiao Zhen looked at the rich canteen meal, looked at each other and smiled.

At this time, the radio sounded: "Candidates and parents who eat in the cafeteria, please note that there are two canteens in our Huaxiong Middle School, the canteen on the first floor and the canteen on the second floor. Everyone is welcome to come to the cafeteria on the second floor to eat, thank you for your cooperation. ”

After the radio rang three times, there was a continuous sound of footsteps in the corridor, and waves of people rushed to the cafeteria on the second floor.

By this time, Lao Wu and Xiao Zhen had already eaten enough and sat on the side to rest.

"Alright, let's go to the library. Lao Wu said.

"Okay, that library is magnificent, and I'd like to check it out. Xiao Zhen said.

However, after walking over, Xiao Zhen found that the library was not open.

So, Xiao Zhen proposed to go to the observatory to have a look.

Lao Wu said: "Do you think that if the library is not open, the observatory will open the door for you to visit the astronomical telescope?"

So, Xiao Zhen quieted down, and followed Lao Wu to the pond at the entrance of Huaxiong Middle School to find a bench and sit down.

"You go to bed first, and I'll wake you up half an hour before the exam. Lao Wu continued.

Because he got up very early in the morning on this day and had a bumpy road, Xiao Zhen was also a little tired at this time, so Xiao Zhen snored while lying in Lao Wu's arms.

Looking at the little real who slept beautifully, Lao Wu also happily played with his mobile phone.

By the time Xiao Zhen woke up, it was already 1:40 p.m.

"Alright, I'm ready to go to the exam. Lao Wu touched Xiao Zhen's head and said.

Originally, Xiao Zhen's head was still a little dizzy, but after looking at the time on Lao Wu's mobile phone, he immediately sobered up.

After taking a sip of water, Xiao Zhen slowly walked up to the laboratory building, and when he entered the classroom, he found that everyone was already waiting in the classroom.

"Wu Zhenzhen, your dad is so good. Xiao Gang, who was sitting on the edge of Xiao Zhen, said.

Xiao Gang is also a classmate for six years, but he has never spoken to Xiao Zhen, so Xiao Zhen is also very surprised at this time.

"Haha, you haven't seen him angry. Xiao Zhen smiled and said.

"How I wish I had a father, even if he was angry with me, even if he beat me every day. Xiao Gang said as tears filled his eyes.

"I'm sorry to bring up your sadness. Xiao Zhen saw that this situation was not good, so he immediately apologized.

"Hehe, it's okay, I don't need pity. Xiao Gang said lightly, wiped his eyes with a napkin, and turned his face back.

Because of this episode, Xiao Zhen in the afternoon math exam has been feeling out of shape.

Problems that could have been done in one minute take two minutes to complete.

For those questions that require a slight turn, it is naturally more difficult.

However, there are not too difficult math problems in Huaxiong Middle School, so there are still a few minutes left after completing them.

However, Xiao Zhen was in no mood to check at this time.

Because of the conversation with Xiao Gang, Xiao Zhen's mentality seemed very confused.

He didn't know how to comfort Xiao Gang, and he didn't know how to adjust his affected psychological state.

However, in the end, Xiao Zhen's mentality was adjusted and he was no longer disturbed by this matter.

However, the time for the exam is almost over.

After handing in the test paper, Xiao Zhen remembered that there were two multiple-choice questions that he had made a mistake. However, by this time, there was no chance to make up for this mistake.

At this time, Xiao Zhen took a look at Xiao Gang's position and found that Xiao Gang had already left the examination room.

At the end, the invigilator gave an explanation to the effect that Huaxiong Middle School has launched a telephone scoring method, and after 9 o'clock in the morning on Monday, the examination room and seat number of candidates can be reported by telephone from the admissions office of Huaxiong Middle School to check the score.

Walking out of the classroom and exchanging moods with his classmates a little, Xiao Zhen followed the crowd and squeezed downstairs.

After squeezing downstairs, Xiao Zhen went downstairs and found Lao Wu lying on the bench by the pond, very comfortable, so he walked over step by step.

Approaching the pond, Xiao Zhen found that some frogs could be heard by the pond, and some dragonflies could also be seen on the lotus canopy.

When Xiao Zhen walked in front of him, Lao Wu saw that the time was only half past three, so he said, "It's still early, go out and take a walk." ”

After getting Xiao Zhen's consent, Lao Wu took Xiao Zhen on the No. 686 bus and stopped at the entrance of a riverside museum.

I saw a sign at the entrance of the museum that read: "Take you into the mysterious age of dinosaurs." ”

After buying the tickets and walking in, the little real discovery - this museum is full of big guys.

"I've wanted to take you to this dinosaur show for a long time, but I haven't had time for the past few weeks, so I'll take a closer look this week. Lao Wu pointed to the Tyrannosaurus rex skeleton a few meters in front of him and said.

Looking at all kinds of dinosaur fossils, Xiao Zhen seemed very happy.

"Wow, triceratops. Looking at the huge head shield and sharp horns on the nearly eight-meter-long Triceratops fossil, Xiao Zhen looked very excited.

Along the way, there are a variety of dinosaur fossils.

Among them, the largest Mamenxi dragon fossil, Xiao Zhen took a few minutes to go around twice and carefully look at each corner.

After getting closer, Xiao Zhen felt that the huge skeleton of the Mamen Xilong seemed to be telling something.

Next, following the various fossils of dinosaurs from huge land overlords to birds gradually soaring into the sky, Xiao Zhen suddenly felt very heavy.

"Dad, why did these guys disappear in the end, and why are only birds left flying now?" Xiao Zhen looked at Lao Wu and said.

"No one can answer this for the time being. Now we can only see the descendants of the dinosaurs still flying proudly, but they can't seem to tell us what happened. Lao Wu thought about it and said.

Xiao Zhen thought for a while and said, "This is really a desperate story, so many dinosaurs have disappeared like this. ”

"It's not entirely like that, it's their exit that gives the mammals a chance to really take center stage. Lao Wu thought about it and said.

However, the brainstorming still continues in the mind of the little real, and a series of question marks keep coming.

Why did these huge creatures spread to every corner of the globe for more than 100 million years, only to disappear without a trace in just a few hundred thousand years?

Only small and delicate descendants are left flying in the sky, and only huge fossils are left underground waiting to be explored by those who come after them.
