"I'm wondering where all that stuff went?" Zhu Run looked at the big dog's still shriveled stomach with a sweaty head, and said in disbelief, "This guy ate all the things I could eat for a week in one go, and now he doesn't react at all, does this guy's stomach be a dimensional bag?"

"Of course not!" The customer service girl shook her head and said, "Its body has been strengthened in all directions now, and the digestive system is the same." Your little stuff was almost digested as soon as it entered the stomach, and it is estimated that there will not be much residue left. ”

"Digested all?" Zhu Run was taken aback, "But so many things have been digested and absorbed, why doesn't it have any effect on it at all." ”

"Because there is not enough nutrition!" The customer service replied as a matter of course, "Think about it, if an airplane is going to fly three times as well, how much aviation gasoline does it take?" If a person doesn't eat, it is estimated that he will have to run out of anemia after running ten kilometers. ”

"Uh, is that what you say?" Zhu Run was a little confused, "But I always feel that something is wrong." ”

"Of course, that's the way it is," the customer service girl said with a heartfelt voice, "whether an airplane burns oil or a creature eats, it is essentially a process of converting matter into energy, and then dissipating and consuming it." If your food is converted into energy, do you think it can support the energy consumption of Wangcai? It's a triple! ”

"Like...... There seems to be some truth. Zhu Run scratched his scalp with some trouble, and then his heart suddenly lit up, as if he had grasped something crucial, but he couldn't figure it out for a while.

He frowned and thought hard for a while, and finally said with some uncertainty: "Xiaoshan, I asked you about energy civilization and technological civilization earlier, and you asked me to ask Wangcai, you won't be talking about this, right?" ”

"That's right!" The customer service girl nodded with a smile and replied: "Why is it that the fifth-level energy civilization that is all illiterate can be called a fifth-level civilization!" And the body is equally powerful, and at the same time, it also has a fifth-level technological civilization that reaches technology, but it can only be a fifth-level civilization! The answer to this question is simple, just two words: eat. ”

"Poof!" Zhu Runting fell to the ground when he heard this, then got up and shouted to the customer service girl with black lines on his face: "Xiaoshan! You're kidding me! You have been mysterious for a long time, and you don't answer when I ask you the difference, let me be true to myself. As a result, you told me that the difference between the two is eating, and you are teasing me! You're definitely kidding me! ”

"Who teased you!" The customer service girl said dissatisfiedly, "I mean seriously, the key difference between them is in the meal." Of course, eating is only a superficial statement, but in fact, it is really a complicated matter. ”

Zhu Run heard this, frowned and thought for a long time to understand what the difference was, and finally had to give up and said to the customer service girl: "Okay! Explain it. Anyway, I can't understand the difference, isn't it just a meal, can it be related to the high level of civilization? ”

"Of course it does, and it's critical." The customer service girl said, "Do you think it's so easy to maintain a strong body?" If you think about it, in the army of your earthlings, if you do a lot of physical training, you have to supplement people's nutrition, and if you encounter a battle, you must also have high-calorie food, otherwise you can't maintain your body in high-intensity combat.

The physical strength of the cosmic race, the fourth level is just the threshold, and the fifth level is considered the official cosmic race. How powerful that kind of body is, they are completely free from the various innate restrictions brought to them by the planet, their bones will not become fragile because they live in a gravityless environment, their internal organs will not be diseased because they have been away from the planet for a long time, they will not be killed by various cosmic rays because they have lost the protection of the atmosphere, and they can bear hundreds of g's gravitational increase when they enter the planet. And like Wangcai, it can run three times as much.

Yes! They are all very powerful, but all of them must have a premise, that is, they have to be well fed and have enough nutrients. An ordinary person only needs about two kilograms of food and water a day to meet the needs of survival, while a blue whale needs 2~4 tons of krill every day to avoid starvation. So how big is the gap between the nutritional needs of an ordinary human and an individual of a cosmic race? I think it's definitely bigger than the gap with the blue whale, at least the blue whale will not end up much better than humans in space. ”

"Ugh! I can understand this," Zhu Run said with some embarrassment, "but now you seem to be a little far away, we are talking about the difference between energy civilization and technology civilization in terms of level, right?" Does it have anything to do with how much the cosmic people eat? ”

"Of course it does!" The customer service girl answered him, and then asked him a question, "How do you think the types of civilization and the level of civilization are divided?" And where does the standard of the cosmic race come from? ”

"Ugh! Isn't this the founder of the interstellar Taobao black market, Lord saInaTan? Zhu Run asked strangely, "Isn't it?" ”

"Of course I know it's salient saInaTan," the agent rolled his eyes, "I'm asking why he did it in the first place, and what is the basis for the criteria?" He can't just point to this and say that this is an energy civilization and a scientific and technological civilization, right? Many energy civilizations still use technological products after entering the universe, and I haven't seen them being classified into technological civilizations. And the division of the cosmic race is the same, he can't always look at this pleasing to the eye, just say that he is qualified to become a cosmic race, that is not pleasing to the eye, right? ”

"This ......" Zhu Run thought for a while and said, "I really don't know about this, to be honest, I really haven't thought about it." ”

"Actually, it's very simple," the customer service girl doesn't sell off, "It's something that happens almost every day to you earthlings, and that's war." ”

"War? Oh...... I understand," Zhu Run nodded suddenly, "Indeed, only war is the easiest way to distinguish between these things. Could it be that it was because there was once a fifth-level energy civilization that was all illiterate that defeated a fifth-level scientific and technological civilization, so the two levels would be the same? ”

"That's right!" The customer service girl said, "Wars between the universe are happening every day, and Lord saInaTan has seen countless wars. Originally, the boundaries of various civilizations in the universe were not very clear, and there was no such thing as a cosmic race. Most of the cosmic civilizations are roughly divided into their respective civilization levels based on the average combat effectiveness of the main warships of their respective civilizations. And the social system is still in the Middle Ages, and there is hardly any scientific and technological energy civilization, so it is natural to be considered a primitive civilization that has just exhibited the fire of civilization.

But then a classic cosmic war was born, and it was this war that separated the energy civilization that was originally considered a primitive civilization, and also formally established the standard of the cosmic race. ”

"What kind of cosmic war is it?" Zhu Run asked curiously, "When did it happen?" ”

"It's been a long time, it is said to be in the primeval era of the universe," the customer service girl replied, "The specific time is not recorded and cannot be queried, but the general thing has been widely circulated in the universe, so I will tell you about the information I found."

It is said that this war is actually not big, and at the beginning it was just a routine occupation operation of a fifth-level cosmic civilization against a newly emerged primitive civilization, and generally speaking, it was not difficult at all. In fact, the medieval planet, which was still ruled by religion, had almost no resistance under the call of religious personnel, and everyone became slaves of this fifth-level civilization.

At this point, if this is the end of the matter, then there will be one more slave civilization in the universe at most. Perhaps in a few years, this civilization will die out on its own, and it will have no effect on the entire universe. But the problem is that that fifth-level civilization made a stupid decision.

In the eyes of that fifth-level civilization, this primitive civilization race may not be worthy of being called intelligent creatures at all, because their civilization is too backward and has no use value for them, and even the most basic housekeeping machine qì people are better at working than them. They thought that instead of letting these guys occupy the planet alive, it would be better to destroy them and take the planet for themselves. And at that time, the race of that primitive civilization, under the bewitchment of those religious personnel, had already regarded the people of that fifth-level civilization as gods, so they didn't think about guarding against them at all. And so, the massacre began......

In the end, there was only one million left on the entire planet. These millions of people were transported to the colonization planets of this fifth-level civilization, and then kept in captivity in zoos to let people witness their bravery and ...... backward civilizations Benevolent.

Well, although I don't know exactly where the mercy is, that's what the official explanation says.

Things soon take a dramatic turn for the worse, as the survivors of the zoo survive the first difficult and frightening days. They were amazed to see how fragile the guys they had always thought were gods. These so-called 'gods' are not as strong as their newborn babies, and they need steel vehicles to make sounds. They need strong defenses to safely break through the planet's gravity and reach outer space. In some colonial stars with harsh natural conditions, in order to isolate various rays from the universe, they even built a canopy that can block the sun......

Therefore, primitive civilizations have a common feature, that is, the worship of the strong. When that fifth-level civilization descended from the sky, under the bewitchment of religious personnel, these turtles who had never flown to the sky naturally believed those nonsense and regarded this civilization as gods. It was when they were slaughtered that although their hearts were full of grief and indignation, they were more resigned to their fate. For in their view, the slaughter of the weak by the strong is justified, and they themselves often do so. Moreover, they believe that they are not capable of rebelling against their 'gods' at all.

However, when they realize that these so-called 'gods' are actually so vulnerable, they naturally think of themselves as strong beings. Thus, a great catastrophe began, centered on the zoos of the various colonies, and all the more prosperous administrative planets of this civilization exploded into a massacre. These guys who came out of the zoo met this civilians of the fifth level civilization, like lions breaking into a flock. No, or should I say more like a man breaking into a flock of sheep and kicking several to death with a single kick. The number of people imprisoned in the zoo on each planet may not be large, but there will always be thousands, which is equivalent to thousands of people killing people on Earth at the same time.

Although the technology of the fifth-level civilization is reached, the power of the weapons is naturally very powerful. However, as civilians, at most, they have some weapons for self-defense, and it is impossible for them to have powerful weapons. It's like your country on Earth, where citizens have the right to buy guns, but they can't buy cannons. Well, maybe cannons can be bought, but shells certainly can't be bought.

These self-defense weapons are as ridiculous as toys against those who can achieve the sound, and it is impossible to even hit. Moreover, it is impossible to station a large number of troops inside the prosperous planet, just like those big cities on the earth, so by the time that fifth-level civilization reacted, countless planets had already fallen. The most unfortunate one belonged to their Duxing, where there was the largest zoo, and the number of the race imprisoned in it reached 100,000, but this Duxing was slaughtered in the first place, making this fifth-level civilization completely lose its leadership system.

After this fifth-level civilization established a new leadership system again, they were stunned to find that except for a few planets without zoos, all the planets were controlled by these primitive races. The surviving civilians of those planets have become hostages, and unless they use high-powered weapons regardless of their casualties, it is impossible to wipe out these civilians. Of course, civilian casualties are acceptable for the sake of civilization if it is really necessary. But what's worse is that those planets also include 9o% of industrial stars, and if you really want to use high-power weapons, then the entire civilization will be over. So they had no choice but to sit down and negotiate.

But there is no doubt that two races with a deep blood feud cannot negotiate anything at all, and the asking price of each side is simply impossible for the other party to accept. So a peculiar war began, the fifth-level civilization that occupies absolute technological superiority has powerful space warships, but because of the fear of civilians and important industrial facilities, there is nowhere to go, and the backward primitive civilization is helpless against the warships in space, so the two sides can only stalemate each other in a small-scale ground war.

Time passed day by day, and now that the fifth-level technological civilization was worried, this primitive civilization had begun to let those who took refuge in them teach them to use technological weapons. With these weapons, combined with their incredibly powerful bodies, it will one day make these guys unmanageable. And this fifth-level civilization, after losing so many industrial planets, even the basic supply of weapons is almost a problem, so this fifth-level civilization began to rack its brains to study countermeasures. In the end, they think that the only way to solve the problem at the least cost is to make their bodies as strong as their opponents, and then have a fair fight with them on the ground.

They took the body of this primitive race as the research direction, and finally developed the first genetic modification liquid in the universe based on the body of this race. This kind of genetic modification liquid can make the body of their own race as powerful as the original race that they have modified. Then they were pleasantly surprised to see how perfect the body was transformed by this race. The explosion of physical and physical combat power is only a small meaning, and more importantly, as long as they are transformed, they can survive freely in the universe. The physiological discomfort that used to require a lot of instruments and drugs to get rid of is now completely out of the question for them.

Since it was during the urgent war, they put it into actual combat after a short period of practice. They named this genetically modified liquid the 'Stairway of the Universe' and used it as a symbol of the peoples of the Six Lands truly stepping into the universe. At the same time, they also understood the name of the 'cosmic race' and called themselves the first cosmic race in the true sense, which is the origin of the so-called cosmic race. ”

"I see," Zhu Run was attracted by the story told by the customer service girl, and savored it carefully for a long time before he couldn't help but sigh, "I didn't expect the origin of the name cosmic race to be so tortuous, and the genetic optimization liquid actually appeared because of this incident."

And what about later? Since the next fifth-level civilization has been transformed, it must be the last to destroy that primitive civilization and finally succeed in regaining the planet? Well...... No, according to what you said earlier, it seems that the primitive civilization defeated the fifth-level technological civilization, so the energy civilization and the technological civilization can be compared in the future.

"That's right! You guessed it," the customer service girl smiled, "Although that fifth-level civilization understands the genetic optimization liquid according to the body standards of that primitive civilization, they haven't delved into why that primitive civilization's body is so powerful." In other words, do you think that just ordinary eating and drinking, plus some physical exercise, can exercise the strength of the body to the level of running sound? ”

"Of course not!" Zhu Run shook his head, "If that's the case, the whole world will be human." ”

"That's the crux of the matter!" The customer service girl said, "That fifth-level civilization doesn't know that the most difficult thing about that primitive civilization is not the strength of his body, but why his body is so strong." ”

"I think I already know," Zhu Run understood everything when he heard this, "they are strong because their bodies are able to absorb the energy of nature. Come to think of it, this is also the origin of the name of energy civilization. ”

"That's right! That's why after this war, Lord saInaTan named that type of civilization so much," the customer service girl nodded, then spread her hands again, and said, "You know it now, but the fifth-level civilization didn't know it at that time!" After they had done a short period of practice, they transformed all the warriors, and then they couldn't wait to send them to the ground battlefield.

If you think about it, when that primitive civilization is fighting, it can replenish energy from the natural world at any time, so it can fight for a long time, but the technological race of that fifth-level civilization is different! All their strength comes from the food they eat every day, and even if they don't fight, they can eat a little more to maintain their daily needs. But once they encounter a high-intensity battle, how much food do you think they need to eat in order to maintain that strong combat effectiveness? ”

When Zhu Run heard this, a drop of cold sweat suddenly dripped from his head, and he looked at Wangcai, who was sluggish, and his expression became very speechless. There is no doubt that the fate of these guys will definitely not be much better than that of Wangcai, and Wangcai ...... It seemed that it didn't add up to a few minutes before he collapsed on the ground hungry.

"So the biggest joke in the history of cosmic warfare was born," the customer service girl couldn't help but laugh, "The fifth-level civilization at the beginning of the war was indeed very good!" After descending to the ground, those high-spirited commanders gave an order, and those transformed warriors immediately rushed towards the position of that primitive civilization like a tiger descending from the mountain. The amount of the tide scared everyone of that primitive race into peeing, but the result ......," the customer service girl rolled her eyes at this, "but before they could rush halfway, they all lay down!" ”

"Hungry?" Zhu Run couldn't help but roll his eyes.

"Hungry!" The customer service girl nodded, "Everyone is starving, and that primitive civilization didn't even bother to do anything in the end, so it directly let these guys starve to death." Then this primitive civilization won the war, occupied that technological civilization, and turned all the people of that technological civilization into its own slaves. Well, it's said that this civilization has now reached level 16! ”

"They all starved to death," Zhu Run listened embarrassedly, "The creator of the cosmic race standard ended up like this, is this the most outrageous sling I have ever heard of counterattacking the rich and handsome?" ”

"No way! It's hard to believe," the customer service girl said, "but that's the way it is." Now you understand why energy civilizations, even if they are all illiterate, can be classified as a level 5 civilization! ”

"But this seems to be a hero based on success or failure!" Zhu Run frowned and said, "If the war was born in the universe at that time, and that fifth-level scientific and technological civilization didn't need to throw a rat trap, then wouldn't they be dead?" And according to what you say, if there is enough food, then I will transform all the people on the earth into a fifth-level civilization, so can't it also be called a fifth-level civilization? ”

"Theoretically, that's what you can say!" The customer service girl smiled, "But there is another characteristic of energy civilization, that is, they can absorb energy and then keep upgrading." For them, the fifth level of physical strength is just a process and not a destination. When you reach the ninth level of civilization, you can survive in the universe without relying on any technological items, and it is not impossible to fight against ships even in the flesh. Moreover, if they can continue to evolve, then maybe one day, they will become the top civilization of level 2O.

But the ordinary cosmic race can't, basically the fifth-level strength body is the end, because their body can't absorb the energy from the outside world at all. Do you remember the bottle of Level 10 Genetic Optimization Liquid you bought, and the combat effectiveness of that little flat head was not much higher after using it. Level 10 Gene Optimization Solution, to put it bluntly, means that the optimization success rate is higher and safer. Of course, other biochemical civilization is another standard, so I won't discuss it here.

If you do what you said now, transform all the bodies of earthlings into level five. So in addition to being physically stronger, you don't have the technology to reach it, and you can't absorb energy to evolve like an energy civilization, so why do you think you can be called a fifth-level civilization? ”

Zhu Run was dumbfounded when he heard this. Indeed, if this can also be regarded as a fifth-level civilization, then civilization promotion is too simple, just buy a genetic modification device.

"And! The big question is," the customer service girl laughed, "do you really think there will be enough food?" Just look at Wangcai, you can see that if you eat food for a week, it's not enough for people to stuff their teeth. If all the earthlings are really transformed, not to mention the improvement of civilization, it is estimated that within a week, all the earthlings who have eaten up the stored food will starve to death. ”

"Ugh! It seems to be true," Zhu Run pressed his temples with a headache, "So, what is the use of us buying that genetic modification device?" Is it just to create a prosperous fortune? ”

"Of course it's useful," the customer service girl smiled, "Isn't there still that Scaron and those Earth cultivators to study now?" They can also be regarded as energy civilizations, and they may be able to study something when the time comes. Well, don't talk about this first, get something to eat for Wangcai first, otherwise it will starve to death if it continues like this. Well, ordinary high-energy nutrient solution, specially designed for emergency nutrition replenishment of ordinary cosmic races. Do I need to buy 10 Star Coins? ”

"Okay!" Zhu Run looked at Wangcai, who was almost faint from hunger, and sighed helplessly, "Then buy it!" You can't watch it starve to death, so let's think of a way to talk about it later. ”
