After a night's rest, everyone finally set out on a journey to find the ancient tomb today. "Hurry up, Xu Xia, we're leaving soon." "Oh, here we are." Xu Xia picked up his backpack and said to An Ran and Chen Tangtang who were standing beside him: "An Ran, Tangtang, you just wait for me at home, so you don't have to go with me." "Brother Xu Xia, you must come back early." An Ran looked at Xu Xia and said with a worried expression. "Don't worry." Xu Xia smiled at her and turned to leave. "Xu Xia, you must come back." Looking at the back of Xu Xia leaving, Chen Tangtang's hand clenched tightly. "Xiaofu, let's go." Seeing Xu Xia come out, Uncle Tang said to Xiaofu. Xiaofu didn't say a word, just nodded and walked forward. Everyone followed behind him and walked towards the depths of the Qin Mountains. Xu Xia and his party walked on the path near the edge of the cliff, and a thick fog began to rise around them. "Everyone, stop." Leng Xuan, who was following behind everyone, suddenly spoke, and everyone stopped. "Little brother, what's wrong, what's going on?" Uncle Tang turned his head and asked suspiciously. "This fog is poisonous, get out of here." Looking at Uncle Tang's puzzled eyes, Leng Xuan said lightly. "What, the mist is poisonous." Xu Xia and the others were all taken aback, and Xu Xia opened his mouth and asked, "Little brother, what's going on?" Leng Xuan glanced at him lightly and said, "This is not a mist, but a miasma containing a highly poisonous miasma." "Miasma?" Hearing Leng Xuan's words, everyone was taken aback. "What is miasma?" Looking at the frightened appearance of everyone, the fat man couldn't help but speak. "Sure enough, those who don't know are not afraid. Xu Xia, you tell him, what is this miasma? Uncle Tang glanced at the fat man and said. Xu Xia grabbed the fat man's shoulder and said: "Miasma is the poisonous gas generated by the decay of animals and plants in the tropical primeval forest, the main reason is that no one can effectively dispose of the dead bodies of animals, and the tropical temperature is too high, which creates favorable conditions for the production of miasma, so miasma is generated." However, "miasma" is not necessarily "qi", and people's understanding of miasma in ancient times was very limited, and most of the actual pathogenic miasma was caused by mosquito swarms. A large number of mosquitoes with falciparum malaria bacteria gathered together to fly, and from a distance it looked like a black and dreary gas. Humans and animals are infected with falciparum malaria when they are bitten by them. We often see in movies that people fall down after the miasma of smoke in the forest, which is actually caused by swarms of mosquitoes, which can transmit falciparum malaria. Chinese call malaria miasma, and in Italian, malaria is called "yin wind", which can be described as the same. There are a few folk songs in Xishuangbanna, China: "Ten people go to Mengla, and nine people are difficult to go home; To get to Che Fonan, first buy a coffin board; If you want to go to Bodhisattva Dam, marry your wife first" very vividly describes the harm of malaria to human beings. Xu Xia's words made the fat man in a fog, and he asked suspiciously: "Xu Xia, what do you mean by this?" "Well, IQ is really a hard injury." Xu Xia couldn't help but shake his head and said: "Miasma has two meanings, one is the poisonous gas generated by the decay of animals and plants in the tropical primeval forest, and the other is what we often call malaria.

Now you get the idea. "Understood." The fat man nodded, and said dissatisfiedly: "Xu Xia, it's not good for you to do this, I won't understand if you said this earlier." "Who is like you, you don't study hard, and you only know how to play lol all day long." Xu Xia looked at him and couldn't help but shake his head. "Alright, let's not linger here." Uncle Tang opened his mouth and asked, "Xiaofu, is there any other way here?" Xiaofu nodded and walked into the woods beside the path. The people followed him and went into the grove. "Whew." Everyone walked out of the grove with a long sigh of relief. It was a forest, and the whole was a mass grave, all kinds of graves, and even the white bones that emerged from the ground, and the stench of corpses filled the entire grove. "Gross." As soon as he walked out of the grove, the fat man threw up violently while holding on to a small tree beside the road. "It's not comfortable." Xu Xia patted the fat man's shoulder and said with a smile. "Xu Xia, why don't you have anything to do, I'm almost sick to death." The fat man raised his head and looked at Xu Xia with a prostrated expression. "I don't feel it at all." Xu Xia looked at him with a smile and said, "I'm an archaeologist, and I often deal with corpses and skeletons, so I don't feel it at all. "I kind of understand why some people say that archaeologists are all non-humans, this is too strong to bear." The fat man looked at Xu Xia and spoke. "Huh." Xu Xia smiled and said, "Okay, have you finished vomiting, after vomiting, we should leave." "Let's go, let's go." The fat man waved his hand and straightened up. The fat man staggered, swaying towards the front, looking at his appearance, Xu Xia couldn't help but shake his head and said, "Forget it, I'll help you go." With that, Xu Xia helped the fat man and walked forward. To be continued.
