Huo Xiake sighed: "Yes, we are the investigators hired by him. According to his wishes, the investigation was carried out in secret. ”

Zou Ping muttered to himself: "I thought that someone would murder him, but I didn't expect that he would actually freeze to death, it's too evil!" ”

Huo Xiake sighed: "We also feel incredible. ”

At this time, they suddenly heard someone expressing their opinions on this matter, and they couldn't help but turn their heads together, but they saw Zhuo Siwen talking eloquently, and the little girl Wang Mengxin looked adoring.

"Although I am not a professional, I have written mystery novels before and have a certain reasoning ability, and after watching the scene, I have several questions: The first is how did Zhang Tianyu freeze to death? You know, he has hands and feet, his mind is normal, if he feels cold, he will naturally be frozen awake, then he can leave the room to find someone to ask for help, and even hide in the quilt to die, but he just lay on the floor and was frozen to death, it is really evil. Secondly, how were the windows broken? It was because of the broken windows that the fierce cold wind blew in and froze him to death. Well, hostess, what is the approximate temperature outside now? ”

Zhou Xiaolan thought for a while and said, "It should be minus 25 degrees." It is colder at night, close to minus thirty degrees. ”

Huo Xiake interjected and said: "The second question, I can help you answer, the person who broke the glass should be Zhang Tianyu himself." ”

Zhuo Siwen asked curiously, "Why him?" ”

Huo Xiake said with a smile: "Everyone has seen the scene, have you noticed that there are not a few glass fragments under the windows of the scene." ”

In retrospect, it was.

Huo Xiake explained: "If the window is broken from the outside, then the glass chips will be carried into the room, and vice versa. There are almost no glass chips left on the floor of the site, and it can be seen that the windows are broken from the inside out. Also, there is a cliff outside the window, and there is nothing to break into. In addition......"

Huo Xiake asked Zhou Xiaolan: "Is there anything missing in Zhang Tianyu's room?" ”

Zhou Xiaolan recalled it carefully, and suddenly remembered and exclaimed: "Yes, the glass ashtray on the bedside table is missing." ”

Huo Xiake shrugged and said, "Maybe Zhang Tianyu smashed the glass of the window with an ashtray." ”

Zhuo Siwen asked curiously: "Why don't you think about it, what is the reason why a sleeping person will smash the glass with an ashtray in the cold and snowy winter." ”

Wang Mengxin immediately replied: "I know, I feel depressed." ”

Everyone immediately focused their attention on the little girl, and her little face immediately turned red and became embarrassed.

"Stuffy?" Huo Xiake turned to ask Zhou Xiaolan, "Is the structure of the room the same?" What's so special about Zhang Tianyu's room? ”

Zhou Xiaolan shook her head and said: "All the rooms are the same, the rooms are big, and you won't be bored if you stay inside, I think everyone knows it deeply." ”

Everyone nodded, and Wang Mengxin hurriedly explained: "Maybe it's a personal reason, such as a physical problem, it's easy to get depressed." I know a classmate who is very fat, easy to breathe, easily stuffy, and has to open the window to breathe. ”

Hua Jiao said: "It's not uncommon for men to be prone to poor breathing. ”

Huo Xiake said: "Okay, count Zhang Tianyu not breathing well. Then it can be expanded as follows: In the middle of the night, Zhang Tianyu suddenly felt stuffy, so he woke up, picked up the ashtray on the coffee table, fell off the bed, struggled to climb to the window, threw the ashtray over, smashed the glass of the window, and then was frozen to death...... Rank, do you think this thing is very contrary to common sense? ”

Hua Jiao said: "I think it's very strange, Zhang Tianyu's posture is very strange. If the average person wants to smash the window, he can pick up the ashtray next to him and throw it over in bed. But he crawled on the ground and got close enough to break the window. Breathlessness to the point where the body functions are uncoordinated, and it is even impossible to walk, and must crawl over, which is unlikely unless ......"

"Unless what?" Zou Ping asked anxiously.

Hua Jiao said: "In my experience, unless he has a physical problem, such as a sudden serious illness, or poisoning!" ”

Zou Ping immediately denied: "Impossible, Mr. Zhang's physique is very good, there is no problem with running a marathon, and there is no problem found in the routine physical examination, not like a sick person." ”

Hua Jiao said: "Diseases that can make the body's functions unbalanced are nothing more than cerebral hemorrhage, heart disease, stroke, etc. However, these diseases are very dangerous, once they occur, they can't even move, and their lives are normal. So I think there is a greater possibility of poisoning, such as drug poisoning, what medicine he took before going to bed, resulting in toxic effects or allergies. ”

Huo Xiake immediately stood up and said, "Everyone, you can accompany me to Zhang Tianyu's room to check his relics and see if there is any medicine." ”

Of course Hua Jiao went, Zou Ping also stood up, and unexpectedly, the young man Yun Ping'an stood up with great interest and shouted, "I'll go and see it too." ”

So these people, plus Zhou Xiaolan - she had to close the door and go to Zhang Tianyu's room together.

This time, everyone had experience and put on thick clothes, but when they opened the door, the cold wind still made everyone shiver.

Under the gaze of everyone, Huo Xiake opened Zhang Tianyu's bag with trembling hands, searched it, and found no medicine, and no residue of medicine was found in the trash can, which means that he had not taken medicine.

Everyone was shivering from the cold, and hurriedly ran away from the scene, helped Zhou Xiaolan seal the door together, and returned to the hall.

As soon as he returned to the hall and felt the warm fireplace, Huo Xia sighed with relief: "It's finally alive, it's so cold!" ”

Zhou Xiaolan said apologetically: "I'm sorry, I can't use the boiler, there is no heating." Luckily there was a fireplace in the hall and a fireplace in the room to keep warm. ”

Hua Jiao was suddenly stunned, and shouted in a lost voice: "Fireplace? ”

Huo Xiake asked strangely, "What did you think of?" ”

Hua Jiao said: "Since Zhang Tianyu didn't take medicine, I'm wondering if he will be carbon monoxide poisoning!" When the wood inside the fireplace is not burned sufficiently, carbon monoxide is produced, which is a toxic gas that is colorless and odorless. Once the indoor concentration exceeds 0.2%, a person staying for an hour can be life-threatening. When the concentration is greater than 0.5%, a person who stays indoors for more than a quarter of an hour will die! ”

Huajiao is knowledgeable and can often provide sufficient scientific evidence.

Huo Xiake thought about it carefully, and suddenly realized: "No wonder, this explains all the strange phenomena. First of all, when I examined Zhang Tianyu's body, I found that his lips were red, and people who froze to death were generally blue, and redness is a characteristic sign of carbon monoxide poisoning. Because of a certain situation, Zhang Tianzong woke up in shock, noticed that there was an abnormality in his body, realized that he was poisoned, he was eager to save his life, so he picked up the ashtray, struggled to roll out of bed, climbed to the window, broke the window, and ventilated. It's a pity that he was poisoned too deeply, and soon lost his mobility, but was frozen to death! ”
