"As for the more powerful black hole bombs, two-dimensional plane space weapons, the former can artificially create black holes, but the appearance of black holes will swallow everything in this world without limits, and it is an irreversible weapon of destruction, unless we want to die, we will not use it easily, the latter is space technology, we have no clue, and we can't start it at all."

"Not to mention these destructive weapons, even force field weapons and gravity bombs all require sixth-level crystal nuclei as energy sources, and we can't afford to consume them." The nursery rhyme shook her head, her tone a little helpless.

Zhang Yifeng smacked his tongue when he listened, and finally had an intuitive understanding of the ghost spaceship, it was terrifying, but the premise of horror was that it needed enough energy, and it was often a sixth-level crystal nucleus, a seventh-level crystal nucleus, and it was really unaffordable.

"Don't worry, I won't use the Dark Forest Ship to go to dangerous places." Zhang Yifeng assured the nursery rhyme.

"Well, you have to come and get it when you use the ghost ship, otherwise the ghost ship will burn the crystal nucleus when it moves."

"Okay."

After finishing the matter, Zhang Yifeng said casually: "By the way, when I came here just now, I found that the production lines of robots, laser weapons, and God of War mecha were all suspended, what is going on?"

"Without sufficient materials, it is difficult for a clever woman to cook without rice, otherwise why are we studying the fog beast, the speed of scientific and technological development is too slow, the world is too barren, the resources are insufficient, and a lot of scientific and technological research cannot be carried out, for the continuation of human beings, we can only focus on the field of biological evolution, as long as the fog beast is raised, we will continue to cultivate a large number of sixth-level evolutionaries, and when the Yuan Energy Beast studies and understands, the sixth-level evolutionaries will soon become seventh-level evolutionaries, which is a more promising path for human beings."

"I've decided to mothball those weapons lines, ·com"

Zhang Yifeng suddenly, it is true, compared with the growth of the strength of the follow-up, the development of science and technology is really too slow and slow, and the previously powerful God of War mecha can explode with one punch in front of Zhang Yifeng, like a paper thing.

"Let's discuss, you can also put these production lines away, why don't you give them to me." Zhang Yifeng licked his face and begged.

Nursery rhyme chuckled, "Yes, you can exchange the recipe for Life One." ”

"I've already said that even if I give you the formula, you won't be able to produce it." Zhang Yifeng politely refused, Life No. 1 is his unique hole card, and he has already made a lot of money in the wasteland world, how can he give nursery rhymes.

"That's right, if I give you the production line, you won't be able to produce a God of War mecha, because you can't find special metals in that world, and without these metals, the mecha won't have much power to build."

The nursery rhyme is obviously rejecting Zhang Yifeng, but her words make Zhang Yifeng unable to refute, many materials of God of War mecha, laser weapons, and even robots are not available in the real world, and robots produced in the real world can't even carry firearms.

It is difficult for a good woman to cook without rice.

This applies to the real world as well.

The nursery rhyme doesn't want to give, Zhang Yifeng didn't force it, the things in the real world can completely make the PNG Kingdom lead the world, the scientific and technological achievements of the wasteland world are awesome, and getting over is also the icing on the cake, moreover, Zhang Yifeng has always felt that the technology of the wasteland world is deformed, it is a castle in the air, there is no solid foundation, he doesn't want the real world to fall into such a predicament.

After negotiating with the nursery rhyme, Zhang Yifeng left the Academy of Sciences and sent a communication to Jin Shengzhe of the Sanjiu camp, the golden god of war of the Northern Star Freedom Alliance, and Chisen of the European Federation, inviting them to come to the City of Life as guests, and by the way, talk about the food trade, if it was a simple guest, they would definitely not come so far, but if it was food, they would come to the fart.

Speaking of which, I have to mention Chisen, Moses and Anasta of the South American Alliance, these three guys have a big life, when they fought with the Yaqi Snake, the Yaqi Snake blew itself up, and the aftermath shook the three of them away, because they were not affected much, they did not fall into a coma, and ran away before the black hole was formed, so they regretted missing the trip to the Blue Spirit Space.

The news that they are not dead still broke out on E3.

As expected, I heard that Zhang Yifeng had a large amount of food in his hands, Jin Shengzhe, Arnoldax, and Chisen couldn't sit still, and were ready to get up and come to the City of Life, with their strength in the late seventh level, as long as they didn't die by themselves, there was no problem in being safe to the City of Life, and at the end of the communication, Zhang Yifeng vaguely mentioned that the City of Life could be traded with gold.

The bewildered expressions of the three of them at that time made Zhang Yifeng laugh secretly.

After doing this, Zhang Yifeng relaxed, and went back and forth between the City of Life, Tianfu City, Linhai City, Spark City, Guangming City, Gaolan City, and Tianming City, Cloud City was destroyed by Blue, and the survivors merged into the City of Life.

Between the six cities, there are a large number of mutant beasts, zombies, and mutant beasts are not led by kings, they are completely scattered and brave, zombies are different, and they continue to attack humans under the command of Lan, but they have not launched large-scale attacks on human cities, so that there are constant battles between the six cities, which is exactly what Zhang Yifeng wants to see.

Zombies, mutant beasts, and humans coexist, what a beautiful picture.

A steady stream of crystal nuclei represents an inexhaustible source of wealth.

Coming back from the farthest Guangming City, Zhang Yifeng stayed in the City Lord's Mansion to teach his son to read and write, Xiao Tianyi, who was a few months older than Qingqing, could walk, talk, and was very sensible, but Zhang Yifeng looked at him with a very complicated gaze, and the sound of reading came from the little guy's mouth, and he didn't notice any change in Zhang Yifeng's demeanor.

"Sister Yiqiu, don't be sad......"

"Well, Bai Ling, I'll go back first."

Bai Ling walked in the door, saw Zhang Yifeng and Xiao Tianyi in the hall, with a thick smile on their cold faces, walked to Xiao Tianyi's side and hugged him, Xiao Tianyi smiled at his mother obediently, continued to bury his head in reading, and from time to time he was still writing crookedly on the paper, and his sensible appearance was very pleasing.

"It was Yuan Yiqiu who spoke just now?" Zhang Yifeng asked with a smile.

Bai Ling nodded, "It's Sister Yiqiu." ”

"What's wrong with her?"

"It's okay, it's just that Huang Tianxing doesn't know what's going on, he pulls the guards out to hunt zombies all day long, I heard Sister Yiqiu say that he hasn't been home for a few days, and he doesn't care about Sister Yiqiu when he returns home, Zhang Yifeng, do you say that men like the new and hate the old, it was so good at the beginning, but after a long time, I got tired of it."

"You mean I'm treating you badly?" Zhang Yifeng asked funny.

"Don't change the subject, I didn't talk about you, I'm talking about Huang Tianxing."

"Who told you to beat all the men to death with a stick?" Zhang Yifeng smiled, "The Huang Tianxing I know is not the kind of man who likes the new and hates the old, there should be something wrong, the matter of the two of them, don't mix with it, it's annoying." ”

"Well, if Huang Tianxing dares to start and give up, I can't spare him." Bai Ling waved his small fist and said viciously.
