There was nothing outside the window.

The strange "hissing" sound seemed to come from the water pipe next to the window. And this water pipe has been leading from the eaves to the well cover in the downstairs alley. Its function is naturally to pour rain on rainy days.

Of course, little Kevin doesn't understand this - he's even too small to stick his head out of the window, let alone look at the pipe close to the outer wall.

After thinking about it for a while, he finally gave up looking for the source of the sound and yawned and went to bed.

So I was speechless all night.

Until the next morning, when the window slowly changed from dark to name, and then it was bright again. Little Kevin's mother, who had been busy all morning, finally pushed the door in and woke him up.

Yesterday was Sunday, and today is another Monday - she has to pinch the time to send her child to preparatory school.

I can't help it. After all, I'm a mother. I always hope my children can get more sleep. But school obviously can't be delayed. In two years, the child should go to private middle school like little Demi next door.

She helped her son wash up in a hurry, and then had breakfast safely. She picked up her schoolbag and took the child to the independent preparatory school not far away.

"Hey, Kevin! Come here quickly!"

Just across the street from the school, little Kevin heard a familiar voice calling his name.

He was about to cross the road with his mother. He looked at it carefully. Sure enough, it was his best friend Candice at school. She was waiting for herself at the school gate today!

"Mom, I went first!"

"Wait, look across the street... Oh, really, what if something happens?"

When little Kevin's mother didn't catch it, she saw the child grab the schoolbag in her hand, quickly cross the street and go straight to the little girl standing next to the school gate.

"Tut," but listen to his mother, even if he smashed his tongue, "this boy, just like his father, ran away like a pug when he saw a girl, and he couldn't hold it!"

But after such a murmur, she suddenly couldn't help laughing. After watching her son and the girl walk into the school gate together, she turned and left safely.

However, almost as she turned the other corner, the little girl in the school vestibule reached out and grabbed little Kevin's clothes.

"Wait a minute!"

The girl named Candice looked back and confirmed it carefully before she came up to Kevin with an unknown face and whispered:

"Come with me!"

After that, she didn't give little Kevin time to think. She dragged his clothes and ran to the playground on the right side of the school court.

"Hey! How -"

"Take it easy!"

Kevin wanted to ask a question, but Candice immediately lowered her voice and interrupted him.

"Don't let the teacher at the school gate hear... Of course, let her see! Quietly, just come with me..."

Candice said and ran. She took Kevin all the way through the playground and ran to the small tree forest at the edge of the playground. Although her little hand had not been able to hold on to Kevin's clothes on the way, the latter subconsciously followed her and ran all the way to the innermost wall in the woods.

Until this time, the two children finally stopped running and held the trunk for a long time.

When he was able to speak, little Kevin said intermittently:

"Candice, you... What are you bringing me here for? The teacher will be in the classroom in a while. Do you want us to be late?"

But soon, he saw a proud smile on the face of his good friend opposite.

"Late?" Candice straightened up and forked. "No! To be exact, it's' truancy '!"

"What --"

Little kevin opened his mouth and shook his head.

"No, no, no, why do you suddenly want to play truant... I can't go with you. If my mother knows, she will hang me on the street lamp outside my house!"

"Oh, what a terrible mother!" Candice brushed her lips disapprovingly, and then said with great air. "I tell you, one of my brothers told me that everyone will play truant in middle school - because such students are the coolest, okay?"

"What does that have to do with me?" little Kevin stood up straight, gestured on his head, and then said sadly, "I'm the shortest in the class. I'm sure it has nothing to do with the word 'cool' when I go to middle school! Look, this is not a problem that can be solved by skipping school."

"Kevin!"

Seeing that her good friend refused to play truant, Candice bit her lip and seemed a little angry.

"Didn't you promise me? You can do what I want with me. Why do you go back now? OK, you don't go. I'll ignore you later!"

With this angry remark, Candice turned and walked along the wall. She really didn't want to pay attention to Kevin.

Seeing this, little Kevin behind him immediately tangled in place with embarrassment on his face. For a moment he looked at Candice, who was fading away, and for a moment he looked back at the school at the other end of the forest. His heart was full of hesitation.

But he also knows that Candice is a very boyish girl, and her character is even more direct than most boys. She said that if she ignored herself in the future, she would never be friends with herself again.

After measuring the rebuke between his friend and his mother several times, little Kevin finally gritted his teeth and ran after Candice's back.

"I don't care!"

……

A moment later, under a broken wall at the back of the school, two small figures came from the small wall hole one after another.

"Look! You can come out from here!"

As soon as Kevin came out, before he got up, he looked up and saw Candice cross up again with a proud face.

He nodded helplessly. After carefully looking left and right, he said with a bitter face:

"Well, you're great... Candice, you see I've accompanied you out of school. Should you forgive me?"

"Hum?"

Candice looked at him up and down when she heard the speech. After a while, she said reluctantly:

"All right! For the sake of not running back, we are still good friends."

However, when children are keen on something, they are always very forgetful. No, just finished, Candice immediately waved her hand and a bright smile reappeared on her face.

"Don't stop, it's just the beginning! Follow me!"

After that, she dragged Kevin's clothes and dragged her to the opposite side - there was a river behind the school. It seemed that she wanted to go to the river with Kevin.

And when little Kevin flatted his mouth and dragged along with Candice to another forest across the path, he heard Candice in front say excitedly:

"Kevin, you know what? Yesterday my father took me to visit an uncle near the school. When my father and uncle talked about things, I came here to have a look... Guess what I found?"

"What?" Kevin wondered.

"Guess what!" Candice made a deliberate effort and immediately pulled him reeling. "If I told him directly, it would be boring... It's easy to guess. Do you remember what you said last week?"

"Last week?" Kevin thought as he walked with his head tilted. After taking a few steps, his eyes suddenly lit up. "Is it difficult... Did you find the tree house here?"

I still remember last week, a classmate talked about his older brother after class, saying that his brother built a tree house in his backyard.

It's obviously cool for every child to have such a secret base - at least it's much cooler than playing truant and so on!

At that time, little Kevin said that he also wanted to have his own tree house, and said he was willing to invite Candice as his first guest.

Unfortunately, he can only think about it like that. After all, there are no such strong trees near his house - besides, he can't build a tree house?

However, just as little Kevin was looking forward to looking at Candice's long brown hair behind her head, he shook his head when he saw the other party following him.

"Not a tree house."

The full expectation suddenly failed, and Kevin immediately became listless - indeed, it's wrong to play truant. I'd better try to persuade Candice back later!

But just as he thought about what reason to explain to the teacher about being late, Candice turned to say:

"But... Although it's not a tree house, it's more interesting than a tree house, and it can also be regarded as a secret base that only belongs to the two of us!"

As Candice was saying this, she saw a sudden light in front of her - they finally walked out of the woods by the road!

And that was the moment they came out of the woods. At the bottom of a downward sloping slope, the wide river immediately came into their eyes.

"Right there! See?"

Candice looked at the calm river for a while before reaching out to a place near the river below the slope. When little Kevin heard the sound, he couldn't help looking at it along her finger.

"Oh! What's that? It looks dirty -"

What Candice meant was not difficult to find. Soon he saw a sewer outlet with a large diameter. But it seems that the drain has not discharged sewage for a long time. Although it looks dirty, there is no water trace.

Not long after, the two children walked slowly down the slope and came to the side of the drain.

"I went in yesterday and looked inside -"

"Shh!" little Kevin suddenly covered her mouth and sideways said, "I seem to hear something... Ah! That voice again!"
