Chapter 4:

Tang Mo looked around, there were no other people in the quiet library, and there were no so-called angels and demons.
"Mr. Chen, you can turn off the computer for me. I will go and see if I can still pick up the books from the bookshelf."
The gods nodded and pressed the computer to close the computer.
Tang Mo’s gaze swept away from the right hand of the stick holding the mouse. He strode to the front of the bookshelf, took out a book, and put it back. "Now we can still pick up the books from the bookshelf, so let me confirm... Mr. Chen, have you heard that voice?"
The stick asked a little confused: "You mean let us help the little girl find a book, or else she will die?"
Tang Mo nodded gently, and the two sat on the desk in the service desk. He said: "At present, we belong to the angel camp." Tang said that Tang Mo extended his right hand. The gods sticked together and looked at it. They reacted at once and quickly extended their right hand. There was also an angel wing pattern on the back of the hand.
"Ah, I also have this."
Almost at the same time that the child said the word "angel", Tang Mo found that there was such a grain on the back of his right hand. This intention is more obvious, however, Tang Mo belongs to the angel camp. Most people in China are right-handers. He just asked the gods to help shut down the computer. He wanted to understand the camp of the gods without screaming.
But since the gods are angels, the problem is even more serious.
The stick obviously also thought of this question: "We are both angels, who is the demon?"
This library is exactly the same as the library where Tang Mo is working. Tang Mo opened his drawer and took out a piece of chewing gum from it. He slowly chewed the chewing gum, gave him a stick, frowned, and his fingers rang rhythmically on the table.
"The first possibility, the devil is not the same as us, the devil is not a human. The voice should be related to the black tower. We temporarily assume that this game is the game that Black Tower said three days ago. The black tower is an unknown creature. The devil is like the Black Tower, not human, just our opponent set by the Black Tower."
This said that the stick can fully understand: "So now we have not found other people in the library, only two of us, because the devil does not exist."
Tang Mo nodded: "Well, that's it. But this is a better situation. There is a second possibility, the devil is also human."
The stick is tightly gripping the explosion-proof stick: "He hid it?"
Tang Mo’s line of sight arbitrarily swept from the hand of the stick holding the explosion-proof stick. After a moment, he smiled and said:
It is possible.

An unknown opponent is always more horrible than the known danger.
Tang Mo and the gods and soldiers are divided into two ways. The stick is even thicker than Tang Mo. He went to find the demon who might hide in the library. Tang Mo is going to look at the first and second floors of the library.
Originally, the stick was still very scared. He did not dare to do this kind of thing alone, but Tang Mo said: "The voice said, prohibit violence."
That is to say, the stick is still a bit awkward. When looking for someone, the legs are trembled, and even the explosion-proof sticks are unstable.
But Tang Mo came back in a minute. His face is a bit ugly: "I can't get the stairs."
"what?"

There are two ways to go down the third floor. The first one is to take the employee elevator, and the second is to go down the stairs. I just took the stairs first, but the stairway seems to have an invisible wall to stop me from going. Then I went again. Looking for an employee elevator, the elevator did not start, and there is no way to go."
The gods’ mind turned:
It means that we can only move freely on the third floor. So what is the book we are looking for is not on the third floor?

Tang Mo also thinks this is the case, but the scope of the book is limited to the third floor...
The face of the godsman became very ugly at once. His head turned stiffly and his voice shook slightly: "How many bookshelves do you have on the third floor of your library?"
"Twenty-three."
The gods sticked their eyes: "Why so few!"
Tang Mo is also very helpless.
Which one is up to him?
In the past few months, Director Wang did not know what was mad, saying that he had to learn from the modern library experience in the West, and to transform his own library, he began to rebuild from the third floor. The Suzhou Library has a history of several decades, no different from other city libraries, and its facilities are all aged. After the director remodeled the third floor, he replaced all of the original one hundred bookshelves and bought twenty-three large bookshelves connected together.
Many readers complain that this kind of bookshelf is not easy to move around, and Director Wang has already planned to change the bookshelf next year. It is a pity that people are not as good as days, I am afraid that he has no chance to change bookshelves in his life.
If the scope of the book is limited to the third floor of the library, it is good for Tang Mo and the stick. Although Tang Mo is a library employee, he has been working on the third floor. His gods like to read books on occultism and religion. These books are on the third floor. Both of them are most familiar with the third floor of the library.
There are fewer bookshelves, and it is easier for the devil to burn books. The probability of burning the book is greatly increased.
When both of them were worried, the familiar footsteps screamed from the depths of the bookshelf. When I saw the little girl in the mosaic, Tang Mo had no way to spit out where she came from. The little girl held a small rice bowl in her hand and tied a small pig bib around her neck and snorted.
"Did you find my book?"
The gods shook their heads in frustration: "We haven't started looking."
The little girl said angrily: "You haven't even found it yet!! I was so hard that the teacher didn't pay attention. When I was eating, I sneaked out to find you. The first day was almost over, and I was going home after the afternoon class. If the mother finds it, then it will be finished."
Tang Mo said: "Do you have any clues, have you ever thought about the contents of the book?"
The little girl swayed the double ponytail: "I can't remember."
The gods hurriedly said, "Are you not giving us clues?"
The little girl suddenly said, "Oh, I remembered. I found this feather in the room this morning. Yes, this is the devil's feather! I know, it's definitely not that I lost the book, it was the demon. He stole my book! Their devils are the most bad guys who deceive people. I hate demons the most. Detestable demon, I must catch him, cut off his wings, and put it into the popcorn machine. I fry my favorite popcorn!"
The little girl handed a black feather to Tang Mo’s hand and jumped away.
"Hey! Angels get a hint of 'Devil's Feathers.'"
Tang Mo: "..."
God stick:"……"
After a while, Tang Mo: "...this is our prompt?"
The stick is also a bit aggressive. He thought for a moment: "Does this feather have any other effect?"
Tang Mo touched the feathers and took the feathers twice in the air. This seems to be an ordinary feather, without a magical mana. When Tang Mo tried hard to try out the magical power hidden by it, it was quietly kept as it was, silently mocking.
The light suddenly disappeared at this time.
The gods screamed scared.
The entire library instantly sank into the darkness, and Tang Mo’s heart missed a beat, just as he stood next to the desk, and he subconsciously opened the old-fashioned desk lamp on the table. Hey, the faint yellow light illuminates the one-meter range around the service desk, enveloping Tang Mo and the gods.
Tang Mo's eyes stared at the bookshelves shrouded in darkness.
Tang Mo held back the tension and tried to drive other lights. He found that except for the desk lamp on the desk of the service desk, all other lights could not be opened. The two leaned against the desk at the desk and sat down on the floor.
In this boundless darkness, fear becomes more apparent. The third floor of the entire library, only this dim light, how the light can not shine anywhere else. It seems that there is a huge beast hidden in these darkness, as long as they take a step outside, they will be ruthlessly swallowed into the abdomen.
"Have you heard any sounds!" The gods were afraid to get closer to Tang Mo.
As he said, Tang Mo is also a bit scalp numb. He listened carefully for a while: "No, I didn't hear it."
The gods swallowed his mouth: "How suddenly this day is dark..."
Tang Mo remembered the nursery rhyme that the children began to sing: "Three days and three nights do not speak, the angel devil wants it. Angels can get a hint during the day, the devil can burn a bookcase at night... The day and night of this game is not Is it different from our time flow rate?"
The gods are afraid to think at all.
Tang Mo tried to calm down: "It is two hours."
"what?"
"The game started at 17:52, now it is 19:58, and two hours is a day."
God stick: "Do you have such a good memory?!"
The stick vaguely remembers that before the child sang a song, it seemed that there was indeed a time. But at the time he was terrified, and he would pay attention to that time, let alone remember it. Tang Mo actually remembered?
In fact, Tang Mo was also very surprised. He also found that his memory is now surprisingly good. For example, he still remembers that the little girl's pink bag on Minnie's is a yellow bow with a pink lollipop in her hand.
When is his memory so good?
There is no time to think about this now.
Tang Mo calmly said: "For the time being, assume that two hours is a day, and the nursery rhymes say that for three days and three nights, the little girl will die after three days. So... this 'evening' is presumed to be two hours. At 'evening', the devil will come out to burn the bookshelves."
In the following time, Tang Mo and his gods eyes widened and looked at the darkly painted twenty-three bookshelves.
Although it is known that the game prohibits violence, this unknown fear sweeps over two people. They dare not relax and hold the explosion-proof stick, which is a kind of psychological comfort.
However, after an hour and a half passed, they did not see anyone, nor did they see the scene of the burning bookshelf.
God stick: "Is there really a demon?"
Tang Mo tightened his lips and his eyes turned on the stick: "There should be."
"So why didn't he burn the bookshelf?"
Tang Mo leaned on the desk of the service desk and said with a deep meaning: "I also want to know why he has not burned bookshelves until now."
God stick did not understand his words, Tang Mo has turned his head, clenched the explosion-proof stick and looked at the stick, his eyes deep and deep: "Mr. Chen, why do you think the devil has not burned until now..."
"Boom!"
The huge explosion sounded loudly in the library.
Tang Mo's eyes widened to the place where the explosion sounded. I saw the moment, the fire was shining, and the raging fire swallowed the seventh row of bookshelves. The huge flame looked terrible in the library, and the fire illumined everything. Tang Mo and the gods stick to them all the time, but they didn't see anyone appearing until the flames went out.
In the second day, the little girl walked over with the Minnie bag.
"You haven't found my book yet? Mom went to the uncle's house to be a guest today. I managed to hold her back. She hasn't found my book stolen. I don't know my mother, she will find it. When can you help me find the book?"
Tang Mo’s face was a bit pale, and he licked his temple:
Do you have any clues about the book today?

The little girl was very dissatisfied and said: "I said it, I don't remember, I don't remember, I don't remember!"
Tang Mo reminded: "This is the second day."
When the sentence fell, the little girl didn't talk anymore, but Tang Mo could feel that under this layer of mosaic, the little girl should look at herself with a very weird look. She said: "You are an angel. You have seen so many books. Of course you know the book. I am not an angel. I hate reading books the most. How can I know the clues of a book? You know it!"
"Hey! Angels get hints two ‘Despise from Mosaic’.

Tang Mo: "..."
