A strong fighting race doesn't need the help of others; Yang Zheng looked at Gao Shou with some surprise, but Gao Shou smiled and explained: "No matter how strong a strong woman is, deep down in her heart she longs for protection, help, and care, but it's just a good disguise." ”

Yang Zheng thought for a while and asked, "They are a matriarchal society, I'm afraid it's different, right?" ”

"It's really different, but it's all women, the nature of the human race is almost the same, at most the mind that needs help is much smaller, it doesn't mean that there is none, in addition, the Japanese country will set up a base here, unintentionally disrupting their lives, there will definitely be conflicts, and even wars, no matter how strong the primitive natives are, they can't beat the hot weapons, otherwise the base of the Japanese country can't be established here, and it will be withdrawn long ago." Gao Shou said.

"You mean that the female warrior clan and the Japanese have hatred, and we help them take revenge and destroy the base, with a common goal, but there is no conflict of interest, because we don't occupy there, so we have the possibility of cooperation?" Yang Zheng said in a deep voice.

"That's right, help aside, we have a common enemy, why not? Even if we don't cooperate, we won't be attacked by the female warrior clan when we attack the base, they may choose to watch the fire from the other side, or they may choose the yellow finch behind, but at least they won't do it when we attack the base, once the base is destroyed and we evacuate quickly, they won't be too embarrassed. Gao Shou carefully analyzed.

"Makes sense, it seems that we have to visit them first before the mission, but how do we find them?" Yang Zheng said, pondering.

"It's not difficult, find the nearby indigenous tribes, I heard that there are many so-called guerrillas here, in fact, they are bandits, drug dealers and illegal armed forces, but they like to use the name guerrillas, they should know some clues." The high leader proposed.

Yang Zheng really didn't know that there were so-called guerrillas in this forest, thought about it, and said: "It's too risky to find guerrillas, the first choice is the local tribe, the local natives must know a lot, followed by the so-called guerrillas, fatty, check it out, see how to deal with these tribes or guerrillas?" Yang Zheng said.

"Yes." The fat man, who was busy, hurriedly agreed.

"One last question, what's going on with this wave of energy?" Yang Zheng said in a deep voice.

Gao Shou shook his head and said with a wry smile: "This is the biggest problem, I'm worried that it is a kind of radiation, didn't Ah Mei say it, the story mentions that this forest makes people dizzy, if it is radiation, we are afraid that we will not be able to enter, unless we find a solution to radiation, otherwise, we will faint when we go in." ”

"Radiation? You are more educated than me, tell me, what kind of situation is there radiation? Yang Zheng asked.

"Radiation sources can be divided into natural radiation sources and artificial radiation sources, and natural radiation sources are divided into cosmic rays, terrestrial radiation sources, radiation sources in the air, radiation sources in water, and radiation sources in the human body; Artificial radiation sources can be divided into medical radiation sources, public radiation sources and occupational radiation sources. Gao Shou said.

"Why can't it be an artificial radiation source? There's a base here, can't it be the radiation they made? Ah Mei suddenly reminded.

"I don't rule out this possibility, but I don't think it's very likely, the Japanese base will not be here for too long, and your story doesn't say that a long, long time ago, this forest made people dizzy, that is, the radiation source was there before the Japanese built the base." Gao Shou explained.

"Makes sense, but what kind of radiation would it be? The Japanese were able to build a base here, how did they solve the radiation problem? Yang Zheng asked, without higher education, the disadvantages of insufficient culture have been exposed.

Fortunately, Gao Shou is highly educated and knows a lot of things, so he thought about it and shouted: "Magician, you are good at magic reform, and you are better than me in the fields of chemical industry and materials, let's study it together." ”

"Here we are." The magician, who was looking up the information, agreed, and hurried over.

Yang Zheng poured a cup of tea for the magician and said with a smile: "You have a high level of education, it depends on you." ”

"I tried my best, mainly because of the lack of clues, and it was difficult to deduce." The magician smiled wryly.

"Elimination method, one by one." Yang Zheng said with a smile.

"Yes, your idea is good, let's use the elimination method, first exclude artificial radiation, start with the analysis of natural radiation sources, cosmic rays, terrestrial radiation sources, radiation sources in the air, radiation sources in water and radiation sources in the human body, there are just a few of them, which do you think is the most likely?" Gao asked rhetorically.

"Cosmic rays are high-energy particle radiation from the universe, which is mainly composed of some protons, α particles and atomic number Z>3 nuclei, cosmic rays have a strong penetrating ability, when shooting to the earth, collide with the atoms of matter in the atmosphere, and various types of reactions occur to produce secondary cosmic rays. Due to the shielding effect of the atmosphere, the total amount of cosmic radiation reaching the Earth's surface is greatly reduced. The magician said in a deep voice.

"I haven't read a book, tell me something I can understand." Ah Mei said a little anxiously.

"Well, actually, I don't understand that when neutrons in cosmic rays interact with nitrogen atoms in the atmosphere, they produce a very important radionuclide 14C, which reacts with 14N (n,p) 14C. With a half-life of 14C of 5692 years, it will diffuse into the lower atmosphere, where it will be absorbed by organisms. The magician explained.

Maybe I think it's too professional to say this, but after thinking about it, he explained: "Let's put it this way, cosmic rays come from the universe, and they are not aimed at a certain place alone, and we are fine here, which means that this is not the case there." ”

"I understand what you say." Ah Mei smiled awkwardly.

The magician also smiled bitterly, not knowing how to answer, Yang Zheng smiled: "My sister and I haven't gone to school, I really don't understand, but you don't need to worry about anything, just say it, continue." ”

"Yes." The magician hurriedly agreed: "The second is the radiation source on land, there are two major types of natural radionuclides on the earth, one is the radionuclide with a decay series, that is, uranium, thorium, actinide, each system can decay more than a dozen times in a row before becoming a stable nuclide offspring, the parent elements are heavy natural radionuclides with atomic number greater than 83, and the half-life is more than 1010 years; The second category is the natural radionuclides of the non-decay series, such as 40K, 87Rb, etc. ”

After speaking, the magician looked at Yang Zheng, saw that Yang Zheng was at a loss, and explained with some embarrassment: "Captain, let's put it this way, some areas of the world have a relatively high radioactive background, and I suspect that there is some kind of mineral under this forest that we don't know, emitting a radiation wave that affects the ecological environment of this forest." ”

"Are you sure it's minerals?" Gao Shou asked.
