The technology tree of prehistoric civilizations involves various aspects, and Shang Yue first chose the classification of weapons and equipment.

The pinnacle of weaponry technology is undoubtedly starship.

Even the smallest starship has its own life support and circulation system, has dozens of independent small combat mechs and spacecraft, has its own weapon system and defense system, has different amounts of energy sources, and guarantees self-recovery in the event of some energy source failure or damage.

Starships can operate independently on the powerful AI Starship Core. Of course, if you want to use the full power of a starship, you need hundreds or thousands of crew members or specialized robots to take care of each task independently.

Shang Yue was already enthusiastic when he saw this introduction, if he brought himself a starship, it would be really cool.

"Mina, how much energy does it take to build a starship?" Shang Yue asked curiously.

"Many, many, many." Mina shook her calf, "In the prehistoric civilization, a total of seven starships were built. The eighth starship was still under construction, and the third cosmic war broke out, and the end was that before the eighth starship was built, the galaxy was destroyed. ”

"Damn, that's no play, then Niu X's prehistoric civilization can only build seven starships, I think I'm afraid there will be no play before I die." Shang Yue gloomed.

Mina thought for a moment, "You can't say that. In fact, this is the thing, because the technological civilization of prehistoric humans has long stood at the top of the galaxy, so no alien race dares to argue with humans, and they hide far away when they see humans. That's why human beings don't have any pursuit of technology. Starships or anything are built casually, and they don't matter. ”

"Prehistoric humans are so powerful, what is the reason why human beings need to choose to die with the galaxy in the third cosmic war?" Shang Yue became more and more curious.

Mina's answer to this question is as always: "When all prehistoric civilizations are restored, we may know." ”

Shang Yue studied all kinds of weapons, and it can only be said that the weapons of prehistoric civilizations are a little too explosive, and he didn't choose them well after looking at them for a long time. It was the energy shield in the defensive weapon that made Shang Yue's eyes shine:

[Energy Shield]: Use stored energy to form a protective network around the human body, and use energy to resist any ** damage.

Required: Evolve (recommended) or Power Armor x1, Energy Storage Core x1

With this shield, there is no need for the weapons of prehistoric civilizations that are too explosive, as long as you use the current weapons, you can completely defeat one against a hundred.

The point is that this energy shield is still at the bottom of the tech tree, and it is estimated that it will not be too difficult to recover.

Shang Yue immediately asked Mina: "Mina, what does evolution mean in the need for this energy shield?" ”

"Evolution?! Are you going to evolve? I can help you evolve! Mina suddenly replied excitedly.

"Wait!" It was the first time that Mina was so excited besides eating, which inexplicably made Shang Yue vigilant: "I don't want to evolve!" I'm just asking what evolution means, and there are a lot of technologies that need to evolve in addition to this energy shield, especially weapon technology. ”

"Hmm. Evolution refers to the transformation of your body, so that there are countless nanomachines in the body, these nanomachines have countless benefits, the simplest is that you will never get sick again, the body will be unprecedentedly strengthened, because they are all machines, the strength of the body will also be unprecedentedly improved, according to your current level of civilization, you will not die without throwing a missile on your head. Because nanomachines can also use energy to help you heal your wounds quickly. Mina introduced with great interest, "There are many, many benefits that are simply countless, so, do you want to evolve?" ”

Although it sounds quite tempting, Shang Yue still finds it a bit difficult to accept that he has evolved into a cyborg: "Doesn't this so-called evolution turn people into cyborgs?" Or is it a thinking robot? ”

"You can't be wrong to understand it that even in prehistoric civilizations, only a small number of people were able to accept evolution. Most people still can't accept that they have become cyborgs. Even from another point of view, they would appreciate and adore those who have chosen to evolve," Mina explains.

"I guess it's because of some side effects of this evolution. So only those who seek fame or fortune or want to be worshiped will choose to evolve. ”

"There are no side effects, and if two evolutionary humans marry and have children, their children will be born with machines. Evolved humans by nature. Mina explained.

"Huh? Is it okay to even have children? The side effect that Shang Yue said was indeed that if he became a robot, he might not be able to have children, "Then why are there still so few people who choose to evolve?" ”

Mina pouted: "One reason is that I can't accept myself as an evolutionary person conceptually. There is another important reason that has just been mentioned. Human beings have long stood at the top of the galaxy, lost their pursuits and ideals, and basically all everyone has to do when they are born is to enjoy a happy life until they die. Only the adventurous would consider allowing themselves to evolve. In addition, only all members of the Human Defense Force are required to evolve. ”

"That's it" Shang Yue hesitated, it sounded infinitely tempting, and there were no side effects.

"Uh-huh! So, are you going to evolve?! Mina looked like she was about to act.

Shang Yue was already a little tempted, and when he saw Mina's appearance, he was a little weak-hearted, Mina has always been sometimes reliable and sometimes unreliable, who knows if she will be reliable or unreliable, "Give me a few days to convince my heart." Thank you. ”

Mina shrugged in disappointment.

"And what about power armor? Isn't it okay to have power armor? ”

"Power armor is the equivalent of a robot warrior as you understand it now, and then you go into the operation compartment to control him, do you think it's okay?"

"Damn, you're a mecha warrior?" Shang Yue shook his head, so swagger or forget it, do you really want to evolve? Not only is it completely indistinguishable from the outside, but it also has this super ability. Hey, no, no, I still can't convince myself to become a cyborg!

"What about the energy storage core? How do I need to recover it? Shang Yue put aside the issue of evolution for the time being, and see if this energy core is easier to handle.

Compared to Mina, who was impassioned just now, she was a little absent-minded now: "Don't think about that thing, because I'm a super energy core myself, otherwise how do you think I've been storing so much energy all along?" ”

"Mina, why are you suddenly absent-minded, you really want me to evolve?"

"I'm waiting for the apple."

Damn, this little guy has learned to play with his temper, and he can't believe that Mina is an artificial intelligence anymore!

"The ultra-reliable artificial intelligence Mina will keep pace with the times! In addition, Mina is indeed just a super reliable artificial intelligence. ”

"Don't spy on my mind."

"I just want to know what the hell you think about evolution."

The phone on the table rang, and the caller was Song Liming, and Shang Yue picked it up.

"Shang Ancestor! What the hell are you messing with the Fang representative! 109 cable factory just sent me a notice to terminate all cooperation from tomorrow! What can I do? Song Liming's anxious voice.

"Termination, termination? Aren't there many other cable factories cooperating with us? Shang Yue didn't care.

"But the processing fee of those cable factories together is estimated to be only one or two million a year, and 109 alone has 70 million!" Song Liming's tone was anxious.

Shang Yue was confident: "One or two million is not enough?" That's enough to pay you and the workers. As for 109, hmph, sooner or later they'll have to come and beg me. ”

Song Liming was about to scold his mother when he heard Shang Yue's words: "Oh, ancestor, don't be hard at this time, how can people beg you?" ”

"Okay, okay, you can watch the show with peace of mind." Shang Yue said, "You, it was still a problem when Su Xiao was turned positive with Neiding, and he was short-sighted!" ”

After speaking, Shang Yue hung up the phone.

Song Liming scolded his mother with his hung up mobile phone, Shang Yue, this kid doesn't know how thick the sky is, right? Such a big financier has been annoyed by him, I am anxious for him and worried about me or my short-sightedness? Yes, the emperor is not in a hurry, the eunuch is in a hurry, pull it down! Anyway, it really won't affect his salary income, how he likes to toss and how to toss!

Shang Yue hung up the phone and secretly scolded Fang Guning a few words, but he didn't scold him for cutting off his wealth or anything, but simply felt that this kid was too stupid, he was simply a second shortage!

Shang Yue took his mobile phone and dialed Su Xiao's phone by the way, but he didn't expect that no one answered, why did Su Xiao disappear when he went home? If she hadn't sent a message saying that she slept at home, Shang Yue would have to worry about whether she had lost it.

"Mina, when do you want to see that apple tree? I'm going out to eat. As for evolution, give me some time to think about it. ”

Mina keenly grasped the point of Shang Yue's whole sentence: eating?!

Then Mina rushed into Shang Yue's study with lightning speed: "What are you going to have for dinner?" ”

"I don't know, let's go out for a walk. It's annoying to think about what to eat every day! Shang Yue took Mina's hand and drove to the snack street to eat.

Without hesitation, Mina ate all the stalls on the snack street, and finally Mina stared at a signature "Daidiaoyaki" as if she had discovered a new world!

When it comes to eating, Shang Yue will never be able to resist Mina, so he can only buy one to satisfy Mina's curiosity. I didn't expect Mina to finish eating this one but she was out of control, can you imagine a five-year-old girl with two ponytails standing on the street eating big DIAO grill one bite at a time and looking satisfied? (Please use your imagination to yourself, if you say too much, you will be a sissy).

PS: Around 11 o'clock 3 watches, Shangyue finished the 109 special cable factory. Book friends who went to bed early collected it to read tomorrow. The new books in this issue are all great gods, and Xiao Mina is going to be drowned by the great gods, and the book friends ask for help! Vote for a lot of recommendations!! Mina rolls and begs~~~ The collection can't be less!
