"Haha, our earth's soldiers and armor are not lost to alien technology at all. They have even played a draw!" Lieutenant General Monroe took the lead in clapping.

"Yes, yes! Since this weapon is so powerful, why didn't it be put into the battlefield at the beginning?" a general asked puzzled.

"Very simply, we can't solve the problem of its power supply. Yinggang has a very heavy weight due to its dense structure. Just starting it has consumed huge energy. According to the general chemical energy, it is equivalent to a person carrying a 'fuel tank' as large as a container to walk, not to mention fighting..."

"Why not use controllable nuclear energy?" Hao Zhi took back his ghost face blue armor and came back.

"Controllable nuclear fusion power energy is our only choice before, but its energy level is still not enough. If it is miniaturized, a soldier has to carry a fusion capsule the size of a schoolbag. Moreover, as you have just seen, it can only maintain a endurance of about half an hour. For interstellar warfare, this is also very impractical!

So this project has been put on hold. Now... With this material containing huge energy, we can finally build our own space combat robot team! "

The sixth master thought for a moment and asked, "how many neutron energy batteries can that piece of neutron material support the production? If you start making yourself now, how long can mass production be achieved?"

"We also need the support of the local country. After all, Yinggang resources are strictly controlled by the local country and must be supported by the earth base. If you agree, I will immediately get up and go back to the production base on the earth. If I can obtain the approval and support of the head of state, we will put into production on the earth and put it into the battlefield as soon as possible in ten days!"

"Good! Do it. I'll send someone to contact the head of state immediately, and he will strongly support it!" Bai Zimo turned to the generals, "We still need support for the next stage of fighting with the blood moon people. The combat base on Saturn will enter the battlefield soon. We need to be ready to launch a full-scale war before that. Everyone should protect according to our established battle array. I estimate that the blood moon people will make a comeback soon after they are silent!"

At the flagship base of the Kirin fleet, Hao Zhi was again called by the sixth master to his office for tea. The sixth Master seemed to like to sit and talk, especially for Hao Zhi.

Unlike last time, the two made a pot of jasmine tea and tasted it slowly in a porcelain bowl imitating blue and white.

"I've seen the information of your whole activities on the ship star, including all the recordings..." the sixth master slowly opened the conversation.

"Hmm!" Hao Zhi answered. He didn't know what he was going to say.

"What do you think of the enemy?" the sixth master still asked Hao Zhi's opinion quietly.

"Evaluation? Overall or individual?"

"For example, their head of state, general or something..."

"War maniac, conceited and arrogant, bloodthirsty nation..." Hao Zhi summarized a few words.

"It feels the same as me, but, zizicarlo... What do you think? After all, he is the only guy who shows a sense of morality similar to us!"

"He let go of Lele after catching us. To be honest, I was quite moved at that time. I thought he was a general with a bottom line. However, there was one thing I couldn't tell clearly. That was his eyes. I always felt that he hid something, but I didn't know what the Tao was. To be honest, I was very confused!"

"We need to know the blood moon race and our opponents before we can respond according to the situation. Your action has obtained a lot of useful battlefield information, which plays a vital role in the decision-making of the land country... To be honest, the head of state and I once had the idea of accepting the discussions and requests of the blood moon people, but this time I saw the blood moon people's terrible breeding After the ability, it was eliminated. "

"Yes, I used to think it's best not to fight, and the blood moon people don't want much. It's just a place to stand, but now I don't think so. If they are allowed to reproduce, the living space of people on earth will soon be extremely limited!"

The sixth master nodded approvingly, suddenly changed the topic and asked, "have you ever thought about the reasons behind such terrible reproductive ability?"

After listening to his question, Hao Zhi considered this question for the first time. Isn't it the nature of a species? Is there any other information hidden?

"Hey, I'm afraid you didn't even notice the hidden information you brought back for us..." the sixth master smiled proudly, "at least help us see what kind of race the blood moon is!"

"Oh? What do you think?"

"Have you heard of the population density theory?"

"I'd like to hear the details..." Hao Zhi looked at the sixth master curiously.

Bai Zimo picked up his tea bowl, gently shook the clear and transparent tea, blew the tea floating on it, and drank: "just like this tea, the proportional relationship between it and water, more tea and less water is bitter, less tea and more water, and tasteless..."

"You mean there is such a relationship between biology and environment?" Hao Zhi said carefully.

"Yes, in a certain natural environment, the number of biological populations is fixed. Beyond this range, if the population is allowed to reproduce, the living space of a single organism will be small and the food resources will be insufficient, which will affect the overall quality of the population.

For example, in a piece of land, the total amount of nutrition in the land is fixed, so the height and density of the grass growing on it must have a certain proportion. If the density is too large, if you want to obtain more sunshine resources, you must strive to grow up and be a head higher than other grass to obtain survival resources, and unrestricted growth will soon deplete the nutrition in the soil, which In that case, everyone will wither and die.

Therefore, in order to balance, when the grass grows wildly, sheep will eat the excess grass, so that the remaining grass can get more nutrition distribution and grow better.

If the sheep grow unrestricted, the only result is that the grass will be eaten up soon, and the sheep will face the situation of starvation... "

"So there must be wolves to eat part of the sheep!" Hao Zhishun continued with the words of the sixth master.

"Smart... In this way, there is a food chain and energy flow between biological populations, which creates the whole biological world. The environment nurtures organisms, and organisms change the environment in turn... But one law is firm, that is the principle of competition exclusion!"

"Competitive exclusivity?"

"Yes! This was first proposed by Darwin. After several generations of biologists' research and promotion, it was finally named competition exclusion theory, also known as competition substitution theory, by Professor Harding in 1960. It means that food and other species with similar living requirements can not continue to coexist in the same place due to the results of the struggle between populations. The only possible result is that one of them will retreat Out of competition, eliminated.

It is needless to say that carnivores delimit their own territory. Even herbivores, it seems that antelopes and bison live in the same space. In fact, their food is also different. Some specialize in grass leaves and some specialize in stems... "

"That's why you think earth people and blood moon people can't coexist?"

"The negotiation and survival of the blood moon people buried their great confidence in their survival ability, but it also vaguely reflected a more important thing!" the sixth master's words became sharp gradually.

Hao Zhi almost said this sentence at the same time, his body shook, and the cup in his hand almost couldn't hold it and fell to the ground: "symbiosis is exclusive!"

"Yes, symbiosis is exclusive! Those who can't live will perish, or escape into the deep space..." Bai Zimo said this, and both of them fell into silence for a long time
