Walking along the road at the entrance of the library is the road to the laboratory building.

Shi Yuan deliberately went to see what the large piece of pure green in the northeast corner of the school on the map was.

The answer is a large wooded area.

Shi Yuan was even stranger.

He pulled out the student code and looked at the map.

Sure enough, the laboratory building and an area to the east of the lake were dark green, labeled "grove".

The forest in front of him was a large area of light green on the map, without any markings.

It's all woods, why are they only marked with small forests?

Is it an omission?

Shi Yuan walked along the road, bypassing this large forest, and arrived at the back of the laboratory building, in front of the small forest marked on the map.

The air here is cold and doesn't smell good.

Unlike that large wood, this grove is surrounded by barbed wire and is completely off-limits to students.

Moreover, this grove is also much thicker, Shi Yuan can see a large number of shrubs under the trees, and there is no waste of space at all, it is almost as dense as the rainforest of Shi Yuan's last mission.

The grove has a door, but it's also locked, but the cylinder is not rusty.

Behind the gate is a path into the forest, which is not eroded by weeds.

This proves that this road is often walked, but what to do in it, Shi Yuan does not know.

The code and the sign in front of the door clearly stated that it was forbidden to enter here, so Shi Yuan did not plan to directly break the rules and force his way in now, so he could only take a look at the door first.

At least not yet.

Shi Yuan looked at the map and turned his head and walked towards the lake.

As soon as he got close to the lake, Shi Yuan already felt a more obvious coldness.

It was obviously noon, but the school was still shrouded in mist, so that Shi Yuan could not feel the heat of the sun.

The lake is located in front of the laboratory building, with Teaching Building No. 4 to the west and Administrative Building A, which is closed to students, to the south.

When he came to the lake, Shi Yuan was already too cold to stand it, although the lake was full of liquid water, but this lake was still like a big ice cave, transporting cold air to the surroundings.

It's so cold, there must be something big wrong with this lake, it's too obvious.

But what the problem is, Shi Yuan doesn't know, he can only observe first to see if he can see anything.

The surface of the lake is quite wide, with slight ripples.

Only a little reed can be seen by the lake, and the water of this lake should not be very shallow.

But the water is not clear, it is pale green, and you can't see anything at the bottom of the lake.

The fog at noon was thin, and the visibility was okay, and Shi Yuan could vaguely see several white buildings on the other side of the lake.

The buildings are marked on the map as the school's water treatment plant.

Nothing special.

Shi Yuan suddenly remembered, so he flipped to the student card and looked at it, the grades were still excellent, but the credits became 80.

It's changed again......

It's 78 in the classroom, 95 in the dormitory, and 80 by the lake.

Shi Yuan still couldn't figure it out.

The last place Shi Yuan wanted to see was the park in the southwest corner of the school.

The park also occupies a large area on the map.

When Shi Yuan came to the park, he found that when he entered the school gate, he saw a wall full of ivy on the left, which was actually the wall of the park.

Shi Yuan could see that the two gates of the park were open on the side of the main road of the school, and one gate was the main entrance, which was wide open, and students came and went from time to time.

The other is a closed back door.

Shi Yuan walked in the door and looked, and the first thing he saw was the lawn bench and willow pavilion that the park had, and he could also see a small fountain.

In the distance, you can see long hedgerows.

"Hey, Shi Yuan, there's a sign behind it." The bear behind the first emperor said.

Shi Yuan hurriedly turned around, and sure enough, he saw a half-exposed wooden sign under the ivy on the wall next to the door.

The wooden sign is nailed to the wall, it looks very shabby, the words on it look old, the color of some words is almost worn out, and the lower half of the wooden sign has old traces of falling off:

Park Bulletin

1. Always remember that there are two exits in the park, so if you can't find the other exit, you can go back the way you came.

2. If you are not prepared, do not challenge the hedge maze, you will get nothing.

3. The well in the center of the park has been abandoned, please bring your own drinking water if necessary.

4. Ignore the robin, you don't know

5. Cats are like lovers, original

6. Night

That's right, because this plank has been too long, the second half of the fourth or fifth sentence and the sixth full sentence of the announcement have completely fallen off, and Shi Yuan can't tell what was originally written no matter how he looks at it.

Shi Yuan frowned.

Compared to the instructions for students, several of the park's announcements are completely dumb riddles.

The first half of the instructions for students mentions that in the second half, "if you can't find another exit, you can go back the way you came." "Isn't that a nonsense? It is also written on the sign.

"If you don't prepare for the hedge maze, you'll get nowhere."

What does this preparation mean?

The third is quite normal and easy to understand.

The fourth is to ignore the robin, this student must know that it has been said, but what will be followed by the "you don't know"?

You don't know how scary a robin is?

Kind of makes sense.

Maybe that's true.

Article 5: Shi Yuan looked even more blind.

"Cats are like lovers"?

What does this say? A completely inexplicable sentence.

It is followed by the word "original".

Original what?

Originally?

Originally?

Cause?

Yes, why!

The latter half of the sentence is likely to explain the reason why cats are like lovers.

But what does this have to do with parks?

Shi Yuan couldn't figure it out.

He remembered the warning about cats in the Student Instructions: strange cats can spread diseases, stay away.

This warning and the park's announcement are incompatible.

Does infectious disease have anything to do with a loved one?

Could this cat be infected with syphilis and AIDS?

Don't, that's outrageous.

Shi Yuan could only put down this sentence first, and there was only one word left in the sixth article at the end: night.

What happened to the night?

Is there anything special about the park changing at night?

Then you can only come at night.

Shi Yuan briefly analyzed the announcement, and always felt that something was wrong.

He opened the student code and looked at it, and found the one about the park:

There is currently only one entrance to the park! Remember!

Shi Yuan looked up at the park's announcement again: Always remember that there are two exits in the park, and if you can't find the other exit, you can go back the way you came.

Shi Yuan was stunned.

Why are the contents of the two rules conflicting?

Which one should you believe?

Still don't believe it?
