The first ray of sunshine in the morning shone on the island, and the seabirds began to wake up. They spread their wings in the wind and rain and hovered over the island.

With the passage of time, the rain gradually stopped and the wind became smaller. After the typhoon, the island was shrouded in a faint mist, like a cloud of smoke.

In the happiness hotel of Nansha Island, the day has just begun.

Uncle Wang looked out from the floor-to-ceiling windows of the living room. From this angle, he could see that in the past, only the front hall was left of the cake house with colorful lights, and the back part had been burned into a mass of charred ruins.

In the typhoon this morning, two people were killed in the cake house because of the explosion and fire.

Those are all living people, who are still talking and doing things at night, and in the early hours of the morning, they are buried in a sea of explosions and fires.

That family seems to be cursed, and is frequently loved by death.

Uncle Wang lived so close, so he knew a little bit about the secrets of the cake house. He also found that some guests behaved strangely. The hotel cleaners found some balloons in the room while cleaning. He has always wondered whether the disappearance of the girl before had something to do with the cake house.

The people in the village talked a lot about the cake shop, but no one tacitly agreed, and there was no other reason. Everyone had no grudge against Qian.

The cake shop can attract tourists to this small island. If there are customers, there will be business, and everyone's life will be better.

Even, Uncle Wang was afraid in his heart, and hoped that the business of the cake shop would be better.

Thinking of this, Uncle Wang let out a long sigh.

By now, it seems that it is too late to do anything.

The cake shop has been destroyed, but the life of the people on the island has to go on.

This might be a bad thing, it might be a good thing.

At least, he will no longer be afraid, afraid of being implicated by what the cake house sells and what he does.

Uncle Wang got up and went to prepare breakfast for the guests as usual.

At eight o'clock in the morning, the typhoon had already passed, but the communication had not been restored.

The islanders on the island should have also heard the loud noise last night and saw the fire, but they did not dare to go up to the cliff to check. Over the years, the upper and lower cliffs have long been two distinct worlds. Although they communicated, they did not interfere with each other.

Several people in the hotel did not sleep well last night.

In the early morning, when Qiu Lan woke up, she found that the girl had woken up a long time ago. She was wearing a T-shirt that Qiu Lan gave her, lying beside the hotel window, staring blankly at the cake house after it burned. of the ruins.

Qiu Lan walked over and looked in that direction, which used to be the girl's home. Qiu Lan touched the girl's hair, and the girl turned to look at her. The little girl's big eyes were still swollen and looked pitiful.

Qiu Lan felt sorry for this girl, afraid that she would catch a cold, so she brought her a red coat and a pair of cropped trousers. Li Ting'er was not very old, but her neck was slender and her height was not low. Although Qiu Lan was an adult, she was not taller than her. how high.

The girl put on Qiu Lan's clothes, which were only slightly larger, and a hoodie wore a cloak effect. Reminiscent of Little Red Riding Hood in the forest.

At eight o'clock in the morning, the two took the girl downstairs to have breakfast together.

When passing by the hall, the two girls glanced out. Various plants outside had already been blown up and down by the typhoon, and many low-lying places had also flooded, leaving traces of the typhoon raging everywhere.

Qiu Lan was a little scared, and she quickly looked back. She didn't know how the people who were still in the cake house yesterday would be burned at this time. A charred mummy automatically appeared in her mind, and she was a little scared...

Li Ting'er followed behind them, walking with her head down, not knowing what she was thinking.

By the time they walked to the restaurant downstairs, the hotel's breakfast had already been set up, and those breakfasts were not much in style, but they were still steaming hot.

Teacher Su has also sat at the dining table and greeted them.

The door of the restaurant was still ajar, and they didn't have time to eat breakfast. They just brought a few samples to the girl when they saw Lu Siyu and Song Wen walking downstairs.

Early in the morning, the two of them didn't know where they had been, and the corners of their clothes were still a little wet.

Song Wen saw the two girls, and then his eyes fell on the little girl, he stepped forward and said to Qiu Lan: "About the explosion last night, we still have something to ask this girl, you and Jiang Jiangneng Can't you just avoid it?"

Qiu Lan was not on guard, Song Wen suddenly took the initiative to talk to her, and suddenly became nervous: "Ah... that... Then let's take breakfast and eat."

Then she and Jiang Jiang discussed a few words, and the two of them took the tray and took the breakfast upstairs.

Mr. Su stood up and said, "What are you asking? Would it be better for me to avoid it?"

Lu Siyu turned his head and said, "Mr. Su, you are here. You'd better be a witness when we ask her."

Teacher Su sighed and sat back again.

Song Wen closed the door of the restaurant, and there were only four of them in the room for a while.

The milk for breakfast is hot, and the porridge is steaming hot.

Song Wen got up and wanted to get breakfast, but Lu Siyu took into account the injury on his wrist and helped him get a few items before serving himself a bowl of porridge.

Song Wen took it with his other hand and sat on the opposite side of the table with him.

The girl, the teacher, and the two policemen sat on both sides of the long table, looking at each other, silent for a while. It seems that everyone gathers here just to enjoy this not-so-heavy breakfast.

Song Wen was not in a hurry to start, and pulled up his sleeves with his hands, seemingly inadvertently opening the scene: "This morning, after getting up, we went to see the scene of the fire last night."

Teacher Su was a little surprised: "No wonder... you got up so early." Then he asked again, "In that fire scene... Is there anyone else?"

Song Wen shook his head and said, "In the explosion last night, there were no other survivors."

Teacher Su said: "Then you have seen..."

Song Wen nodded: "Two scorched corpses were found."

Teacher Su suddenly felt that the breakfast in his hand was not fragrant, and Li Wan'er also opened her eyes wide in fear.

Lu Siyu was accustomed to these topics for a long time, and he drank his porridge calmly by the side.

After a while, Teacher Su lowered his head and sighed.

Li Ting'er raised her head and asked in a low voice, "The baker and my mother, they were all burned to death, right?"

Song Wen snorted: "The two corpses should be your mother and the cake chef Yang Ling."

Li Ting'er lowered her head, her eyes were slightly red, but her expression seemed to be relieved.

Song Wen continued: "But... we found some traces over there this morning. We suspect that last night's accident was not an accident. So, Li Ting'er, can you give us some more clues?"

Professor Su, who was on the side, heard this and let out an "ah". Then he looked at the girl beside him in surprise.

"No... Impossible!" Li Ting'er said these words subconsciously, and then she whispered, "I... I think the explosion this morning was very sudden, it should be an accident, why do you say that?"

Lu Siyu suddenly stopped drinking porridge, turned his head to look at her, and asked softly, "You don't want to know, why did your mother and the baker get killed?"

The girl was sitting on the high chair in the restaurant, still much lower than Lu Siyu. At this moment, she raised her head, her face full of innocence and innocence, she shook her head timidly and said, "I can't think of anyone. would want them dead."

"Who on earth wants them to die?" Lu Siyu turned his head sideways, Junxiu's face expressionless, "I think I should ask you this question."

After hearing this, Teacher Su was stunned.

The girl raised her eyes as if she didn't understand, and asked, "What?"

Seeing the girl pretending to be confused, Lu Siyu didn't want to say more, so he buried his head and enjoyed the breakfast in front of him.

Song Wen looked at the ten-year-old girl in front of him and continued to explain: "We originally thought that the explosion last night was an accident, but this morning, we checked the scene carefully and found something interesting. ."

"What we found was a few pieces of plastic scattered in several places in the storage room. The contents were burnt to a scorch, but it was still recognizable. It used to contain flour. I started to think it was made of The cake container, and then we figured out that the explosion was a deliberate murder, and it was probably a dust explosion."

"Dust explosion?" Professor Su was even more surprised when he heard these words, "How did this dust explosion cause?"

Song Wen explained: "The essence of dust explosion is a violent oxidation reaction. When there is 9.7g of flour per cubic meter of air, it will explode when it encounters an open flame."

"The elements required for a dust explosion are the following: a relatively closed confined space, combustible diffusing dust in the air, and the thermal energy that causes the dust explosion, which is an open flame."

Song Wen's clear voice continued, "That hut should be the storage room of the cake shop, there is not much space there, not only the flammable laughing gas is stored, but also a lot of flour, coffee powder, sugar powder, etc. for making cakes. Dust. Dust explosions are characterized by low ignition energy, multiple explosions, and strong destructive power, not to mention that there are many other flammables in the storage room.”

9.7g of flour per cubic meter, this figure and conditions are actually very easy to achieve, and because of this, many flour mills and dust-raising factories prohibit open flames.

Professor Su frowned and said, "Then so... it was a fire caused by a dust explosion last night? But why do you say it wasn't an accident..."

"Someone put flour in some plastic buckets filled with sand in advance, and then made a simple little trap to hang several buckets full of flour with ropes and connect them to the door of the storage room, once someone opened it. The door, those kegs fell to the ground, and the dust was raised, and at this time, just a small spark would…”

Song Wen's eyes were fixed on Li Ting'er, not letting go of any subtle expressions on the girl's face, and then he made a gesture of opening his fingers, "At that time, there will be a bang, causing an explosion and turning everything into a bang. For nothing."

Hearing this, the little girl lowered her head and pursed her lips, which was obviously a nervous action. Such an expression naturally could not hide from Song Wen's eyes.

"Last night, there was a sudden power outage in the cake shop. Due to the typhoon, wind and rain, the storage room should have leaked water in the past, so Yan Min, the owner of the cake shop, has the habit of checking the storage room. She woke up in the middle of the night, She wanted to see if there was a leak in the storage room. She should have taken a mobile phone or a flashlight, but she didn't expect that as soon as she opened the door of the storage room, she heard a few strange noises, and then there was fog, and the light of the flashlight was not enough to illuminate the inside. , can't see the situation clearly."

Song Wen paused and looked at Li Ting'er, "Just using a small bucket to fill the hut with flour, even if you are found, you can tell your mother that it's just a prank. If your mother was calm enough back then , will find that the crisis is around, she will close the door and go out, and the tragedy will not happen."

"It's a pity that in the middle of the night, she slept in a daze, and her awareness of preventing dust explosions was not strong. At that time, she subconsciously took out the lighter she was carrying and wanted to light the candle, and the accident happened... "

It was just a subconscious action, such a small flame, when it encountered dust, caused a disaster. A series of violent explosions followed, and the fire ignited the flammables in the cake house storage room, causing a disaster.

In the restaurant of the homestay, it was quiet for a while, and the others stopped, only Lu Siyu was eating leisurely.

Song Wen waited for the old man and the young man in front of him to digest his words. He had just described the entire incident.

Professor Su frowned and looked at the little girl sitting beside him, it seemed unacceptable, all these things were done by this innocent looking child in front of him.

If it was really done by a girl, then she probably planned it for a long time.

How does a ten-year-old child carry out such a seemingly complicated plan? How did you come up with this murder method? Why did she kill her own mother? Why does it seem so calm...

Thinking of this, the food in front of Professor Su could no longer be eaten. He took out a tissue and wiped the corner of his mouth.

Li Ting'er was stunned for a few seconds, looked at them and asked in a low voice, "I don't know what kind of bucket, what kind of flour, and, it sounds like this, isn't this an accident?"

Song Wendao: "You can argue or deny it, but we have also found other evidence..."

Li Ting'er's face suddenly turned pale, as if she had remembered something. She opened her eyes wide, still pretending to be innocent, and said stubbornly: "What are you talking about? I don't understand..."

She looks innocent and innocent, dressed in red, just like Little Red Riding Hood in a fairy tale, but she doesn't know that this indifference and calmness far beyond her age betrayed her.

If it was a normal child, I would have burst into tears at this time, and I don't know how to argue.

Lu Siyu had almost eaten, pushed the bowl in front of him, and explained everything more clearly: "Last night, the power outage in the cake house was not an accident, but someone deliberately pulled the switch, that person is you Well... you may have been careful not to leave fingerprints, but you overlooked a little..."

They hadn't figured out why they were also located on the cliff. Yesterday, only the cake house was affected and the power went out, but the hotel where they were staying was business as usual, until Song Wen discovered the hidden traces...

Li Ting'er followed Lu Siyu's question and asked, "What is..."

She didn't realize that she had already revealed her flaws, and the person who wasn't the murderer should say that she didn't do it at this time, instead of asking where the omission was.

Lu Siyu licked his lips and continued: "Because you have just been to the storage room at home, when you were packing the flour, your feet got some flour on your feet. You came out of the storage room and walked through the short open air. , into the hallway. That's when the flour on your feet turns white in the rain and turns into white slime."

"You hurriedly walked through the corridor without leaving too many traces, but when you stood on tiptoe in front of the electric box, and carefully pulled the electric switch, the flour water ran down your trousers and shoes, on the ground. leaving traces..."

Song Wen cooperated and showed Li Ting'er a photo with his mobile phone. It was taken when he and Lu Siyu were surveying the scene in the morning. Lu Siyu used a high-end camera, and he casually took it with his mobile phone.

It was some tiny white marks on the ground.

Li Ting'er looked blankly and asked, "What is this?" Her voice began to tremble.

Lu Siyu leaned his body against the back of the chair and said, "Your footprints." He elaborated again, "The footprints you left under the electric box."

People leave different footprints under different circumstances, and these footprints can reveal the trajectory of movement and various information.

Such a size and such a pattern are enough to prove that the girl once stopped there, and the traces in front of the footprints are more obvious, indicating that she once stood on tiptoes there and tried to pull something. The white elements in the footprints are more obvious. It was able to prove that she had just come out of the storage room.

Lu Siyu looked at Li Ting'er: "Unfortunately, although the fire area was large yesterday, it didn't burn here. Your footprints stained with flour are enough to prove that those buckets of flour are related to you. Last night The power outage was not accidental, but man-made... After the explosion, in the panic, you didn't have a chance to pull the switch back, so you kept the switch off."

Li Tinger may not have thought that the fire did not spread to that part, and the typhoon did not blow there, so her footprints were completely preserved.

As long as it is a man-made plan, no matter how careful it is, it will leave traces. So far, relevant evidence has emerged.

Hearing this, Li Ting'er blinked, she understood, where did she go wrong, the girl still stubbornly retorted: "I don't understand what you are talking about, I was almost burned to death by the fire last night..."

"Last night, there was a sudden fire and thick smoke billowing. That baker Yang Ling didn't even have time to escape the house and was burned to death. How did you, a child, get up from the bed indifferently, put on your shoes, and run out of your room? what?" Lu Siyu asked her.

Li Ting'er looked at Lu Siyu with those big eyes and remained silent. She is very beautiful, innocent, pure and beautiful, she looks like a little angel, and she deserves all the beautiful words to describe her.

Unfortunately, these are just symptomatic phenomena.

Lu Siyu's voice was indifferent and ruthless, and mercilessly pierced through her painted skin: "Because, you were hiding in the front hall, and you had enough time to escape, in order to play the role of a victim, you deliberately did not If you ran out too early, you heard someone entering the fire, you hid under a safer table in the back kitchen, cried, and then pretended to faint."

Under the layers of reasoning, the criminal process and the evidence of the crime are all presented.

Last night, they risked their lives to rescue the culprit of the explosion from the fire.
