The watch in the small box was a little old, with tiny scratches on the glass cover, the outer bezel of the case was badly worn, and the second hand had stopped, making it look like it had been sitting for many years.

It is not a precious watch, probably for children to learn to see the time, marked with sixty small dots, twelve numbers are written clearly, neatly, all painted in color, the color of each number is different, it is easy to attract the attention of children.

The hour hand of the watch points to 1 o'clock, the minute hand points to 11 minutes, the second hand points to 12 seconds, and although the three hands all point to different numbers, they all point in roughly the same direction, all pointing to the upper right, and a small crescent moon is drawn on the back of the watch.

"What is the connection between these three numbers? 13:11:12 seconds, the average value of the three numbers is 12, the password must be a number, you have to add up the single digit and the ten digits, there is only one truth! The password is ...... No, it's not 3, there's a moon behind it, it means that the time is night, the hour hand is not 13 o'clock, it's 1 o'clock in the morning, the average value of 1, 11 and 12 is 8, and the password is 8! Zhou Yu said and made a gesture of holding his glasses.

Nie Sha was in no mood to joke, shook her head, and said, "It's zero." ”

"Zero? How can I not tell that it is zero, these three numbers have something to do with zero? Zhou Yu put down his hand in embarrassment.

"The hour hand refers to 1 o'clock, and that's right." Nie Sha explained: "If you just add up and then take the average, the meaning of the table is not much, it is better to write directly 1, 11, 12 three numbers, 01, 11, 12 The sum of the three numbers is 24, the first place of the three numbers adds up to 2, the second place adds up to 4, it is also 24, you are right to add up the number and the ten digits, if you add it up, it is 6, but when expressing the time, 24 points is very special, it is 0 points, so you don't need to add it." ”

As soon as she finished speaking, the classroom door shattered again.

Chen Fang was still tirelessly chasing after Nie Sha, wanting to tear off her head to avenge the stuffed rabbit, which was not a big threat, but now the second puzzle had been solved.

"Nesha, you're always late, it's hard for me." The tallest boy on the roof walked in through the back door of the classroom, holding a stainless steel ruler in his hand, which was not sharp, but it was still possible to cut me in half.

"Ma Tao......" Nie Sha screamed in surprise, turned her head to Zhou Yu and asked, "He is also a powerful ghost?" ”

Zhou Yu picked up a chair and threw it over, Ma Tao didn't avoid it, his bloodshot eyes stared at Nie Sha, his face was dark and black, and the chair passed directly through his body and hit the wall.

"It's a ghost." Zhou Yu frowned, Ma Tao's movement speed was a little faster than Chen Fang's, but he was still walking, not running.

After going around in circles and rushing out of the classroom door, the two came to the third floor and continued to rummage.

Before he finished looking for a classroom, Ma Tao walked into the classroom, and it was also violently broken, but its strength was smaller than Chen Fang's.

"It seems that there is also a point limit, and if you point strength, you can't point agility." Thinking so, Zhou Yu and Nie Sha moved to another classroom.

Ma Tao's speed greatly reduced the efficiency of finding puzzles, and most of the time was spent on transferring.

Zhou Yu was a little anxious, he didn't believe that other dream hunters hadn't experienced nightmares, ghosts or something should be very common, it was impossible to only have [Ash] as an attack method, otherwise wouldn't the person who had never been able to get [Ash] have no way to do the task?

There must be some way to deal with spirits, what could it be?

The first thing that comes to mind is salt, there are legends that salt can deal with ghosts all over the world, and there are dog blood, donkey hooves, raw rice, peach wood, rush grass, incense, gourd, realgar, cinnabar, red rope, bronze mirror and many other props to ward off ghosts and evil spirits, but these things are unlikely to appear in schools, and the canteen is good to say, it should not be a problem to find salt, but you can't find that thing in the teaching building.

"That's right!" After thinking about it for a long time, Zhou Yu suddenly thought of a method, he didn't know how other dream hunters did it, the only thing that was certain was that that method couldn't be done by other dream hunters.

Yuecheng can swallow the open sky, why can't the teaching building swallow ghosts? It's all dreams, and even if you can't "chew" them to death, it shouldn't be a problem to get trapped.

The question is what to do? It was not his subjective will for Yuecheng to devour Kaitian, and it could only be judged from the fact that Zero Force was taken out to have something to do with him, Zhou Yu didn't know how to control it at all, so he could only recall the mood at that time and let himself enter that realm.

What was your state of mind like at that time?

A hand axe was cut off on his back, his right shoulder was directly chopped with a big hole, his shoulder almost fell off, there was a tempering of white lightning, his ability to withstand pain has far exceeded ordinary people, but the angel had a [phantom pain], which magnified his pain, and he was so painful that he couldn't exert his strength at all, and fell to his knees.

At that time, he was desperate, he didn't want to win, he just wanted to draw, but in that case, a draw was no longer possible, Kaitian was cut in the abdomen by him, but there was still strength left, and he couldn't move.

"Is it just pure despair? It should be more than that. Zhou Yu tried to remember, but was interrupted by the sound of Ma Tao breaking the door, and at the same time, Nie Sha also shouted: "Found it!" ”

She took out a small round object from the podium, pinched it in her hand, and rushed out of the classroom with Zhou Yu.

"Go straight up to the fourth floor." Zhou Yu continued to reminisce and ran up the stairs.

Once the puzzle is in hand, it will be the same wherever it is solved, and after solving it, there will definitely be a chasing ghost, maybe it will appear directly on the third floor, so that they will directly buy time to go up the stairs.

Arriving at a classroom, the two pushed open the door and stood in the doorway, looking in the direction of the stairs while inspecting what they had gotten.

What Nie Sha got was a small round purse, made of imitation leather, only the size of the palm of his hand, which should be a wallet specially used to hold coins, and the front of the wallet was pasted with a three-headed Q version of the Little Mermaid.

Unzipping it open, Nisha took out a small note from her purse, and there were only three symbols written on it: "∠=?" ”

"It's more difficult, and there's no hint at all." Zhou Yu didn't understand how to solve the mystery this time.

Nie Sha also seemed to be stumped, frowning slightly, rummaging through it, and there was nothing else in her wallet.

She looked down and pondered for a moment before saying, "The answer is 4." ”

"How did you get out?" Zhou Yu was very curious.

"∠ is a symbol for corners, and the note is asking how many corners there are." Nisha explained, turning over the table again.

"The wallet is round, there are no corners, and I can only think of zero." Zhou Yu also thought about this problem, but always felt that the puzzle should not be so simple.

Niesha explained: "It's not the horns of this purse, but the 'mermaid's purse' - the eggs of the rays, which are rectangular in shape and have four horns, which are relatively rare in the animal kingdom. ”

"It's a little harder, it's hard for you to come up with it." Zhou Yu gave a thumbs up.

The third puzzle is solved, the first three digits of the password are 2, 0, 4, there are three digits left, there are 1000 combinations, and it can be solved by brute force, but for now, continuing to solve the puzzle is the fastest way.

The puzzle was solved, and without accident, the third ghost also came out, it was a boy who had not spoken on the roof of the building, this time he spoke, walked upstairs with Ma Tao, and said in a deep voice: "Isn't it just looking for you to borrow money to buy a pack of cigarettes?" It's so stingy, it's better to die. ”

He was holding a dagger.

"Hopeless? It can't be just despair, there must be something else in it. Zhou Yu was still thinking.

If devouring happened because of desperation, then there was nothing he could do, his concern for Nie Sha could not be compared to Xiao Hei who fought side by side, even if one was a human and one was a snake, one was real, and the other was just a simple nightmare.

"No, not emotions." Dangerously transferred the two chapters of the classroom, Zhou Yu had an epiphany: "Emotions are generated because of obsession, without the idea of protecting Xiao Hei, there will be no despair, if you want to affect Yuecheng or dreams, you must have a deep obsession." ”

And when he came to Moon City for the first time, the huge transcendent nightmare would be attracted to him and stare at him, also because of his obsession, he was anxious at the time, hoping that the transcendent nightmare would not leave, otherwise it was very likely to be quietly killed by the hidden dragon, and the strong thoughts affected the nightmare and made it stop.

Probably because the nightmare found out that the guy who stopped him was just a poor worm with almost no zero power, and he was still "ordering" it, and he felt angry, so he stared at it.

There must be obsession.

Judging from the current situation, the obsession should be to protect Nie Sha from being harmed by these ghosts, but such thoughts can't be persistent, and no one will have a very strong obsession with a person they meet for the first time, that's too bullshit, and it's not perverted.

It's good to complete the task and get the obsession of zero force.

If you want to increase your zero strength, you have to complete the mission, you have to protect Nesha, and if you want to protect Nesha, you have to prevent these ghosts from approaching......

Looking at the approaching ghosts, Zhou Yu concentrated all his attention.

His attention is easily distracted, but he can also be highly concentrated, and if he is playing a game, then a few hours of high concentration are not a problem, and now it only takes a short time to get through it by willpower.

After a few seconds, the effect appeared.

The ghosts were the first to be affected, they originally only chased Nie Sha and didn't pay attention to Zhou Yu at all, but at this time, the three ghosts all looked at him at the same time, and Ma Tao, who was closest to him, even froze for a moment.

That moment was very short, but Zhou Yu could see it clearly, this was a great improvement.

They had searched the classrooms on the fourth floor, and were now in the teacher's office, which had been rummaged through by Nisha, and finally, under the keyboard of a computer, she found a piece of paper.

There are two paintings on the paper, one is composed of straight lines, the upper left corner is a "ten", there are two short lines on the right side of the cross, like a flush "two", and below the cross and two words there are two long lines, parallel to the two characters, and the two ends of the long line are flush with the "twelve" above.

The other painting is of a crucified baby.
