After everyone ran outside from the cave in a panic, Chen Zhijun nervously asked Professor Chen, "Dad, what is that black smoke?" You're so scared. ”

Professor Chen said to Chen Zhijun with a serious expression: "It's not that I'm afraid! That smoke is poisonous! ”

Chen Zhijun was shocked when he heard this, and continued to ask with wide eyes: "But how did you know that it was poisonous?" What kind of poison could that be? ”

Zhang Gong saw that what Chen Zhijun asked was his strength, so he grabbed the topic and replied: "Brother Gongzi, how can there be smoke in a good coffin?" Think for yourself. ”

"If you think so, I'm going to ask you? This teacher is not qualified at all! ”

"Okay, for the sake of Chen Gongzi's studiousness, let me tell you, the smoke is formed by the spontaneous combustion of white phosphorus or some similar substance hidden in the coffin, and the coffin itself is sealed into the copper coffin, and there is no chance to contact oxygen, because the corpse in the coffin has undergone limited decomposition, and the oxygen in it is slowly consumed to form a relative vacuum environment, and after the water of the corpse is slowly decomposed, in the relative vacuum negative pressure environment, white phosphorus will not have any reaction, when we destroy the environmentThe air entering from the gap in the coffin will squeeze the gas inside to do work, and it will form a short-term heating phenomenon, and the short-term heating is enough to meet the conditions for spontaneous combustion of white phosphorus, then you will know what will happen. ”

"I know that compressed air will produce heat, but you don't explain it in detail, but I can understand it, but this is not compressed air, how can there be instantaneous high temperatures? The smoke of white phosphorus is white, and it smells of garlic, but the smoke here seems to be black, and I don't know the taste, so I ran out before I could smell it. ”

"The air is not completely compressed to produce heat, when a closed space instantly air enters, it will also produce heat, about this you can go back to the school to process your learning, white phosphorus spontaneous combustion smoke is white, if you put white phosphorus into what container for spontaneous combustion, what kind of phenomenon will it be? In addition, the guy in this coffin has a certain sense of revenge, and before he died, he explained what strange chemicals were mixed in it, so what would it be like to burn again? ”

Faced with Zhang Gong's rhetorical question, Chen Zhijun surrendered, but he was still puzzled and continued to ask: "Uncle, how did there be chemical things in ancient times?" I can't figure it out. ”

"In ancient times, many of the tricks of the charlatans were actually the result of chemistry, and most of them deceived people by adding chemical reactions at the same time, but it was not called chemistry, and some things were estimated that they didn't know what they were called at the time, but they just knew that there was such a reaction result."

"Then through the spontaneous combustion of white phosphorus, what does it mean that the people in this coffin are in a state of mind?"

"He must know that phosphorus pentoxide released by spontaneous combustion of white phosphorus can cause damage and death of human organs, and if he wants to poison us, what else can he have?"

In Lao Zhang's explanation, Chen Zhijun finally knew what was going on with the gas released by the zombies in the coffin before jumping out to hurt people in the movie, and after hearing these explanations, he also had a new interest in those magical things in the ancient tomb. Through the discovery of the past few days, several elders from Beijing, including his father, are all equipped with unique skills, and their combination is enough to make everything that happened thousands of years ago without magic. Their knowledge covers all aspects of ancient and modern times, which makes him deeply admire these archaeological team members.

Seeing that there was no smoke inside, Professor Chen asked several team members to wear gas masks and re-enter the cave.

Professor Zhang continued to probe the hole drilled out of the coffin, and then made a general probe of the surrounding environment, and after seeing that there was nothing abnormal in the air, he took off his gas mask and said: "It's okay, some toxic gas residues were detected in the hole in the coffin just now, but I can't be sure what it is. ”

Seeing that there was no threat, Zhang Gong asked Professor Chen: "Old Chen, I feel that the guy here is quite insidious, I will continue to use the snake camera to look inside now?" ”

"Well, take a look, it doesn't hurt, but be careful not to touch what's inside, thinking he'll still be hiding something evil in the coffin."

"Don't worry, if he dares to be dishonest, I'll set him on fire!"

After speaking, Zhang Gong scolded and began to inspect the coffin with a snake camera. After a while, Zhang Gong called Professor Chen to him and said, "Old Chen, the corpse inside is wearing fish scale armor and holding a bronze sword, and there is an iron jar at his feet, and nothing else has been found." ”

Professor Chen moved the camera to the tin can and looked at it and said: "It should be that white phosphorus is placed in it, you see the piece of cloth covered on it, the middle part has been burned, and the black smoke should be released by igniting the cloth through the spontaneous combustion of white phosphorus, and there must be articles on that cloth, which may have soaked something on it." ”

After the plexiglass container was delivered, Lao Ma and the others wore gas masks and pried open the lid of the coffin, and nothing unusual appeared inside.

Professor Chen: When they saw that the coffin had been opened, they all walked up to the coffin and looked inside. Zhang Gong scolded Lao Zhang as soon as he saw the shriveled head inside: "This sharp-beaked monkey's gills are not a good thing at first glance, girl, and there is white phosphorus hidden in his face to make trouble." ”

Professor Chen shook his head and said to Zhang Gong: "You can accumulate some virtue in your mouth, it is normal for people to use small means to protect their corpses." ”

"Is he like this or is it to protect his body? Lao Chen, it's not blowing, there must be other hidden weapons on this product, I don't believe it, I'll try it later! ”

"Let's talk about that later, it's up to you to solve it, you first look at the fish scale armor is the same as the one in the ear chamber of the general's tomb, and the shoes and hats are consistent with that era," said Professor Chen, who gently touched the corpse with his hand, and then said in surprise: "There is also elasticity!" ”

Seeing Professor Chen say this, Chen Zhijun also squeezed up and looked at the corpse in the coffin carefully. The corpse inside is indeed the same as what Zhang Gong scolded, with long sharp-beaked monkey gills, which looks ill-intentioned; The corpse's face and hands were covered with a waxy substance.

Chen Zhijun asked puzzledly: "Dad, why did this person put wax on his body when he died?" Is it to lock in moisture? ”

Hearing this, Professor Chen couldn't help laughing, and Zhang Gong on the side also laughed and said, "Fool, that's corpse wax, not artificially smeared." ”

Chen Zhijun, who looked confused, asked in a daze: "Corpse wax?" Naturally formed by the human body? How does it work? ”

"To put it simply, this is just a cadaveric phenomenon, the corpse decays slowly in water or in a confined moist space, and after a period of time, the subcutaneous fat will be broken down into fatty acids and glycerol, and then into ammonium fatty acids, which will then combine with calcium and magnesium in the water to form cadaveric wax."

After speaking, Zhang Gong gently took out the bronze sword and handed it to Zhu Gong, carefully touched the arms and armor on both sides with his hands, and after a while, Zhang Gong smiled and scolded the dead body: "Old thing, you still play with me, and this kind of indiscriminate trick is also taken out for me to show." ”
