Through the bright moonlight, looking at the modern buildings on both sides of the dark street that are like building blocks piled up, Yifei did not have the previous disgust for the steel city, but a burst of indescribable excitement welled up in his heart, and he whispered to himself: "I'm finally back, my hometown!" ”

"I'm finally back, my hometown!"

…….

"I'm back!" As he continued to whisper to himself for dozens of seconds, he suddenly shouted loudly and excitedly, in the quiet night sky, a deafening voice suddenly sounded over the entire city, and suddenly there was a barking of dogs everywhere.

Immediately, the lights in the dark city began to be lit one after another, and at the same time, noisy sounds began to appear.

"What a bastard boy, screaming in the middle of the night!"

"Grass, I don't sleep in the middle of the night, who is screaming ....... ghost"

…….

Seeing this scene and hearing the sound of complaining in his ears, Yifei suddenly found that he had made a big mistake, and suddenly his figure flashed, and he hid in a dark place on the side of the street, and then a system dialog box popped up in front of his eyes.

[Clerk: Your Majesty, you have found a plane that imitates four-star technology, do you record the coordinates?] Be? Not? 】

Imitation of the four-star technology plane? Looking at the content of the dialog box that popped up in front of him, Yifei couldn't help but wonder why the system would define the Earth in the 21st century as an imitation four-star technology plane?

Thinking of this, he asked in his heart, and then a large amount of information poured into his mind, and as he sorted out the information in his mind, he suddenly understood why the system said that.

According to the setting of the fort level in the system. With the exception of the first era of chaos, the era before the four stars was the foundation for the future. It's like the Age of Steel and the Age of Magic. The most distinctive representative of the Iron Age is the mastery of steel technology, and the Age of Magic Energy is the mastery of energy technology. Only after the foundation has been laid solidly. in order to enter the next era.

And the current situation of the earth is that it has mastered most of the technology of the Iron Age, and has entered the age of magical energy. This originally had nothing to do with it, after all, there was always some correlation between adjacent eras. But the strange thing is that when the earth had just entered the early stage of the era of magic energy, it suddenly came to a ****** again, directly entered the pre-technological era, and began the research and development of various technologies in the technological era.

Instead, they neglected the research and development of the technology of the Iron Age and the Age of Magic Energy, as if the invisible hand behind the earth suddenly raised the civilization of the earth by a large margin. Let it enter the era of science and technology under the condition of unstable foundation.

Without the support of the technology of the Iron Age and the Age of Magic, the earth suddenly entered the age of science and technology, and the rough use of various materials and energy seriously consumed the earth's own resources, resulting in the development of today's civilization suddenly entering a misunderstanding.

By sorting out the information transmitted from the system in his mind, Yifei knew that no matter which civilization it was, after entering the era of real four-star technology. They should have enough strength to develop the resource planets near their own planets, and use the resources of the resource planets to continuously promote the continued development of their own civilization, so as to enter a more advanced era.

And what about the Earth today? In the case of unstable foundation, it constantly consumes its own resources. The progress of civilization has stalled, and it is likely to become a dead planet.

Dead Planet, a planet that can't make it to a post-tech era. Bound to one day, it will be due to the lack of resources. lead to the destruction of an entire planet, to the destruction of an entire civilization. Thus entering a long ice age, waiting for the recovery of the planet, waiting for the recovery of civilization.

Destroy! The destruction of civilization!

At this time, after Yifei understood what was going on, he couldn't help but be anxious, and hurriedly asked in his heart: System, is there any remedy for this?

He knew very well that his future was not here, his future was in that other world, that is, that other plane. The heterogeneous plane that doesn't know how many galaxies it is separated from Earth. At least until he stepped into the seventh-level post-space age, he could only rely on the power of this wish to stay on Earth for a short time.

Only when he enters the post-space era and develops space-time black hole technology, can he lead the space warship to officially visit the earth with the technology of space-time black hole. And at that time, what age the earth was in, he didn't dare to guarantee, after all, where the node of time was.

But when he knew that his hometown would come to an end in the future, he was still anxious, and the kind of attachment in his bones made him unable to watch his hometown go into extinction.

Stronghold Five Stars: Post-Tech/Bio Era; Stronghold Six Stars: Space Age; Fortress Seven Stars: Post-Space Age; Stronghold Eight: Age of Galaxies; Stronghold Nine: Starry Sky Age.

As his question was asked in his heart, the system quickly gave him an answer, looking at the answer given by the system, Yifei couldn't help but breathe a sigh of relief, fortunately, there is still a remedy - to complete the basic technology, before its own resources are exhausted, enter the real era of science and technology, and then develop the resource planet near its own planet.

After getting the answer given by the system, Yifei thought in his heart, completing the basic technology, this matter is simple and simple, and complex and complicated. If the people of Earth realized this and began to vigorously develop basic technology, with some tools from the crude technological era that they already have, it would be possible to do so.

But what if they don't realize it? At this time, Yifei thought of this, and couldn't help but feel a little embarrassed, could it be that he wanted him to go to them directly? Will they believe it? Will you think of yourself as a neuropath?

Just when Yifei was thinking in his heart, a system dialog box suddenly popped up in front of his eyes, and looking at the content of the dialog box, Yifei was suddenly startled.

[Tips: Host, this civilization is too chaotic, a small planet, there are more than 100 forces, the basic technology is not solid, the loss of its own resources is too great, it is estimated that it will enter the rebirth stage in 1745....... it is recommended that the host does not record the coordinates, and the civilization cannot become a cooperative planet in the future of the host......]

And 1745 is about to be destroyed? Looking at the content of the dialog box in front of him, Yifei couldn't help but be stunned, and hurriedly asked in his heart: Why, how is this calculated?

[Tips: According to the development progress of the civilization, the resource consumption of the planet where the civilization is located, and the energy consumption of the center of the earth...... If the civilization continues to consume the resources of its own planet in this way, in 1745, the planet will inevitably have a war for survival due to the lack of resources...... (To be continued. )
