"The air is very good, it changes a lot, don't you introduce it? You are the landlord of this plane. ”

Fang Yan said in a wheelchair, turned his head to look at the middle-aged Fang Yan pushing himself behind him, and then looked at the people and things around him, as well as the future Yanjing full of strangeness and familiarity.

"Then let's talk about the development of this world." The middle-aged dialect nodded, then recalled it slightly, and then spoke again, "Taking 2017 as the starting point, graphene batteries will be put into production and application in the private sector in 2024, and the various electric energy products that have evolved will replace most of the gasoline products in 2041. ”

"Among them, the development process of artificial intelligence is extremely fast, but at the same time, we also restrict, so in 2075, the whole society can be regarded as fully entering the era of artificial intelligence, and three years later, the outbreak of World War III, the original space industry suffered a devastating blow, and the base under construction on the moon was also destroyed."

The middle-aged dialect paused as he spoke, and then thought for a moment, "But the local war under the air-space war was only fought for 3 years, and then we developed a first-generation experimental spacecraft with a speed of 69 km/s, carrying a nuclear fusion reaction device. ”

"And at this time, it is also the end of the war, and after the coordination of all parties, the earth will fully enter the era of the star system." The dialect added.

"That's right, then the Earth Federation was formed, and the Joint Space Agency was established on April 9, 2083." The middle-aged dialect said, and then smiled, "In the next 5 years, nuclear fusion successfully entered the civilian market, and in 2093, the maglev transportation system will completely replace the previous electric energy transportation system, so the cars you see now are all floating." ”

"Not afraid of crashes? It's hard to do this with a population base, right? Fang Yan asked.

"Everything is difficult at the beginning, but it has been solved under intelligent control, and the population problem, although the population is still very large, our current population pressure is not so great." The middle-aged dialect said.

"Three wars?"

"Well, I don't want to mention it, but it's true." The middle-aged dialect nodded, "Our loss is actually not big, but our territory has increased, so the population pressure has also been alleviated." ”

"Interesting." Fang Yan smiled and nodded.

"They hit their heads against the south wall to come back, but they just happened to be cheaper for us." The middle-aged dialect also laughed, and it seemed that his mentality had returned to the age of the dialect, "But Yanjing is still the same, but it won't be stuck in traffic, and those transparent passages in the sky are our current rail system." ”

"Anything else?" Fang Yan asked.

"Education? Employment? Culture? Or whatever, I can talk about all of that. The middle-aged dialect asked rhetorically, and continued to push the dialect towards the front.

"You can talk about it, and it's okay to listen to it."

"Let's start with education." The middle-aged dialect nodded, and then spoke, "The system has changed somewhat, but most of it is still based on cramming education, but we will not limit the development of interests and hobbies, how to put it, it is equivalent to a fusion of foreign education systems and our education system." ”

"Mainly cramming, supplemented by openness." Fang Yan nodded.

"It's pretty much the same, but the main thing is that parents have changed a lot in the way their children are educated, which should be considered a fundamental reason." The middle-aged dialect added, "And then in terms of employment, due to the population and unemployment, intelligent machinery has only replaced a small part of the industry, and most of the industrial chain is still manual, so it has not changed much." ”

"Hmm!" Fang Yan nodded.

"But there are quite a lot of emerging industries, e-sports, virtual games, space tourism, interstellar network, and so on......"

"And after that?" Fang Yan turned his head and looked at the middle-aged Fang Yan behind him again.

"In 2084, we relaunched the lunar base program, as well as the earth defense program, and at the same time, the United States, through some of the information we gave, also launched the first generation in 2091, well, a dilapidated galaxy spacecraft, with a flight speed of 63km/s, followed by Lao Maozi, although ugly, but solid, can have a 64km/s."

"The lunar base was officially completed in 2093 and immediately put into use, and now the development of spacecraft has basically been transferred to the lunar base." The middle-aged dialect said, and a look of pride appeared on his face,

"In 2096, our first-generation galaxy-class space warship began to be finalized, this battleship series is the Whale Shark series, the prototype ship is named Whale Shark, with a speed of 135km/s, a length of 423 meters, a width of 54.5 meters, equipped with 6 nuclear fusion reactors to provide energy, can be equipped with 8 space fighters, equipped with 2 laser launchers, 4 electromagnetic railguns, and the attached attack weapon is missiles."

"But in the subsequent use, we found that it was too versatile, and then the actual combat capability was actually not so strong, so we redesigned it in 2104, and in 2115 produced the first prototype ship, named Whale Shark One, with a speed of 183km/s, canceled his combat cabin, leaving only one for special operations, and the armament remained the same, so his size was reduced, and at the same time, the speed and maneuverability were increased, and the main purpose was, Frontal assault and assault combat! ”

"And the other two warships were born at the same time, multi-purpose warships and supply ships, and our motherships are still being designed, and it is estimated that it will take some time to get them." The middle-aged dialect introduced, thought about it, and still revealed a message.

"The battleship that picked you up is the Whale Shark 2 experimental model, with a speed of 267Km/s per second, and I don't know much about the rest of the data, but the current American battleship is just enough for the tail of our Whale Shark 1."

"Not able to colonize yet?" Fang Yan pondered for a moment and asked.

"Cities on the Moon and Mars have actually already taken some prototypes, and small-scale migration is already underway to lay the foundation for large-scale migration in the future." The middle-aged dialect replied, and then thought for a moment, "It is expected that before I die, I should be able to see Huaxia carrying out large-scale migration in the solar system." ”

"Very good!" Fang Yan nodded.

"It's really good, it's the best of times." The middle-aged dialect also nodded, then scratched his watch, and quickly stopped a hovercar next to him, "Go up and sit down, because of your body, you can't go to the moon base and the Mars base, so you can only try these things." ”

"Okay!" Fang Yan nodded, and under the impetus of the middle-aged Fang Yan, stepped onto the hovercar.

"Where do you want to go?" The middle-aged dialect asked.

"Yanjing roast duck is still there?"

"Of course!" The middle-aged dialect smiled heartily, and at the same time entered the location on the main control screen of the maglev car, and then continued, "Although many traditional skills and cultures did not receive much attention during your period, they were properly inherited in the following time. ”

"Hmm!" Fang Yan nodded, and with the automatic lane change of the maglev train, he silently looked out of the window, quiet and comfortable......
