That night, the five remaining members of the original Salvation Band had a rare reunion outside of the annual meeting period.

They returned to Caiweilou, set up the instruments of the past, and played "Never Walk Alone".

However, the image and voice of Zhong Lei were generated by holographic projection.

The other four people, except Chen Feng, have obviously aged.

But the image of Zhong Lei was perfectly reproduced by the holographic image, just as it was back then, breathtakingly beautiful.

In the hoarse performance, time seemed to go back to that evening of that year, and the Salvation Band, which had appeared briefly at dusk, reappeared in this way many years later.

Fatty Ou, who was already old with white hair but still looked energetic, burst into tears and cried bitterly, which made him even more sad than Chen Feng.

He wiped the sweat from his forehead and said with deep emotion: "I worked very hard to exercise this time, hoping to live longer. Although I still couldn't lose weight, my life has become longer. But why is Sister Lei... Alas!"

Fatty Ou finally listened to Chen Feng and started exercising for at least one hour every day since July 2020.

Unfortunately, it seems that he is fat and fat, and he can only lose a little weight occasionally due to overwork, but after a short rest for a month, he will be round again.

Fortunately, his exercise is indeed effective. He has not lost any fat, but has gained some muscles, and his physical condition has improved a lot, so he is still energetic now.

Fatty Ou knew that he was always the first to die in the rescue. This time he had a rare chance to break his fate, but he didn't expect that Zhong Lei, who was supposed to have the longest life, would die first.

Chen Feng patted him on the shoulder and comforted Fatty.

He smiled and said, "It's okay. Her life may have ended for you. But for me, it may have just begun."

Fatty was puzzled, "Ah?"

Chen Feng didn't explain, but just looked up at the sky.

He knew what kind of changes "The Sun in the Universe" would bring to human civilization.

Zhong Lei will continue to live.

She will live in the memory of mankind in a very stable form, and live in the quantum network established by the stars.

In the past, those "ordinary songs" left by Zhong Lei could constitute a complete star personality.

This time, Chen Feng completed "Stars" first.

Previously, "Stars" has been further absorbing and digesting all of Zhong Lei's works and a lot of information.

Now it has added another song "The Sun in the Universe" that conforms to the Grand Unification Theory.

Then, the traces Zhong Lei left for mankind will always accompany human thoughts and exist forever.

This deadline is not ten thousand years.

Even if "The Sun" disappears in the long river of time after ten thousand years, Zhong Lei's influence on mankind in these ten thousand years will last forever.

Zhong Lei's "death", in a sense, is only the death of the flesh.

Zhong Lei's thoughts will accompany all her works, with "The Sun" as the skeleton, and will always exist in people's hearts.

After a lot of calculations, Stars gave Chen Feng an answer.

If humans can really be eternal, then sooner or later, when humans evolve to a high enough level and their understanding of the universe reaches a deep enough level, "Zhong Lei" will come out of people's hearts again.

Chen Feng believes that if his true quantum immortality is also successful by then, the two will eventually meet again.

That night, the five people who had not drunk for a long time got drunk for the first time. The next morning

, Chen Feng, who was sleeping on the sofa, just opened his eyes and saw Ryan sitting opposite him, holding a large drawing in his hand.

The pattern on the drawing looked like a whirlpool, and also like a tablecloth that was grabbed in the middle and then twisted into several whirlpools.

In this day and age, probably only old-fashioned people like Ryan would use paper and pen to draw.

He also uses a computer on weekdays, and only when he is working on some particularly important and difficult projects will he take out the heirloom paper and pen.

"What is this?"

Chen Feng walked over and asked.

Ryan looked up at him and rubbed his slightly blurry eyes, "I designed the solar system rapid transportation network."

"Huh?"

Chen Feng went over the term in his mind, then picked up the drawing paper and looked at it carefully.

The center of the vortex is marked with the sun in small fly-head letters.

This is a large net that covers most of the solar system like a three-dimensional spider web.

The large net is divided into eight circles from the inside to the outside, and each circle is connected to each other by many arc-shaped pipes.

Ryan explained: "Eight layers of deformable rings will orbit the sun. These connecting arc tube networks are connected to the rings with movable buckles. The inside of the tube network is an ultra-vacuum environment, and we can allow train-like shuttles to enter the ring tube network from the arc tube network."

"Under the continuous acceleration of electromagnetic power, the speed of the space train can reach up to one-third of the speed of light. When switching between the arc and ring tube networks, it only needs to slow down to one-tenth of the speed of light. The transportation network will become the blood vessels of the solar system, transporting large amounts of materials from one place to another in a very short time."

"This can greatly improve the efficiency of resource allocation within the solar system, and further maximize the role of unlimited resources. When we complete the mass-energy conversion equation and the Dyson membrane, we can start implementing it."

Chen Feng watched intently for a long time. This kind of blood vessel-like network has never been adopted in the previous timeline.

He was not sure if this was the right path.

He asked, "When the technological level is not high enough, this may not be cost-effective. After all, we only have a thousand years."

Ryan smiled. "It is definitely cost-effective."

Chen Feng: "Why do you think so?"

Ryan: "You said that the solar system is very important to mankind, right?"

"Yes."

"In the ninth timeline, you said that the main force of humanity should not give up the solar system easily. Although those who left created a lot of new value in the shadow galaxy, it still did not meet your expectations."

Chen Feng nodded, "Yes. This time we will not give up the solar system easily."

There was one thing he did not say.

This time he had new ideas about the war layout in the 31st century.

Assuming that everything goes well, the remaining main force of humanity will be immune to ZS bacteria with the help of Zhong Lei's additional works such as "The Sun in the Universe" and "The Last Millennium", and humans will withstand this wave of biochemical eradication in the 26th century. Then by 3020, the dome must still be above the solar system.

By then, Chen Feng will let the descendants take advantage of the disadvantages of the dome's vague monitoring, so that the external performance of the solar system civilization will remain at a level similar to that in the eighth timeline, and only secretly accumulate technical strength.

When it is around 3000, use the mature planting warship technology to madly expand military strength in just 20 years and ambush the opponent.

Then, the compound eyes will inevitably be misled by the appearance observed in the dome, and the first wave of main combat forces will inevitably be prisms, and there will be no powerful reinforcements that arrived later in the previous timeline.

At the same time, the first choice target must still be the solar system.

According to Chen Feng's preview, the following situation is likely to occur.

The prosperity in the solar system is so high that the compound eyes decisively regard the solar system as the biggest threat.

If the prism fleet can break through the blockade set up by the Morning Wind Empire in advance and reach the solar system.

The opponent will maintain the dome blockade and millions of prisms will be deployed together until the solar system is completely destroyed, and then they will be divided into small pieces to pursue other humans in the galaxy.

But this time, Chen Feng will use the solar system to make them pay for it.

By then, the territory of the Morning Wind Empire will be infinite.

But the main battlefield of the first stage of the war will only be the solar system.

There will only be two directions for the war.

First, the compound eye found that the solar system was a tough nut to crack. Even with millions of frigates on their shoulders, they couldn't take down the solar system. The compound eye left the dome above the solar system, and the frigates dispersed, going out to find the "soft persimmons" first and destroying them one by one, while calling for reinforcements. The hardest bone to chew, the solar system, was saved for last.

Second, the solar system, in turn, used the dome blockade and the desperate strategy of killing one thousand enemies and injuring eight hundred of its own, burying all the millions of frigates in the solar system. Then the enemy's reinforcements will arrive in about 3520 years at the earliest.

The human beings in the solar system will use their own heavy damage as a price to strive for a possible stable development period for the entire Morning Wind Empire.

This can achieve the maximum benefit.

As for the second phase of the war, there are two possibilities.

Assuming the first scenario, the Solar System will be left as the last one.

Chen Feng will find a way to use the Grand Unified Formula to create a way for a small number of human main forces to sneak out of the dome in the 31st century, go outside to lead the war between the Morning Wind Empire and the Compound Eyes, and start the second phase of the war.

If it is the second scenario, even if it seems selfish, he must lead the leadership team in the Solar System to survive, and continue to guide the next 500 years of stable development, rapidly expand strength, and wait for the arrival of another second phase of the war.

If everything goes well, humans can wipe out the compound eyes and counterattack the enemy's lair to completely destroy it, or directly usher in the third stage of the war and face the real super civilization behind the compound eyes.

But no matter what the situation is, Ryan's proposal seems to be very meaningful.

First of all, Ryan's idea does not use too much super technology, which will not cause too much vigilance from the enemy.

Humans in the eighth timeline can complete it, but they were blocked by the dome at that time, and humans could not get out. The intensity of exploitation of the sun was not enough, and energy capture could only rely on the natural combustion of the sun.

With the material production capacity at that time, only ships and aircraft and other means of transportation were needed to complete the transportation work, so it was not done.

But this time, Chen Feng will keep the rapid development technology of stars and build the ultimate stage of Dyson membrane. By then, the material production capacity will completely overwhelm the transportation capacity of ships and vehicles.

Building the blood vessel-like space rail network proposed by Ryan just solves the productivity demand.

Thinking of this, Chen Feng was a little surprised, "Tell me how you came up with this idea?"

Ryan said, "I'm studying the space-time topology you taught me."

"Yeah."

"Although the experimental conditions are not available now, you have told me a clear answer. Mass-energy conversion is achievable, right?"

"Yes."

"Then you also described the Dyson membrane to me, describing a method that can steadily increase the burning speed of the sun. So, I speculate that when the dome arrives, we can only rely on the resources within the solar system. We may even completely burn out the life of the sun within a thousand years and wave goodbye to the hometown that gave birth to us. Then, if we want to maximize the efficiency of our resource utilization, we must build a space vascular network."

Ryan said loudly.

Chen Feng was silent for a long time.

He had to admit that he was shocked by Ryan's sudden burst of amazing analytical ability.

Ryan already had a long-term vision similar to his.

Moreover, his analysis of the development of civilization from a scientific perspective was more accurate and creative than Chen Feng himself.

Ryan's time-space topology had reached a high level.

Chen Feng had thought that it would take Ryan at least another twenty years to reach such a level.

Ryan gave him a big surprise.

Chen Feng habitually reached out and patted Ryan's shoulder, "Well done."

Ryan looked much older than Chen Feng, but he rarely showed a shy smile, "Thank you for the compliment. In fact, this idea just came to me last night. Zhong Lei did this for you, and even gave up decades of her life. I am also your comrade-in-arms, your compatriot. I think I can and must do it."

"Space-time topology is great, but I am older than you, and I don't have as long a lifespan as you. So, I'm sorry, I have to disobey your order this time. You have to train a new successor. Ou Junlang's son, Ou Tianwen, is a good choice. As far as I know, his awakening level is about to reach 30%, right?"

Chen Feng: "Yes."

"That's perfect. I can move forward boldly. Since my talent lies in scientific research and innovation, I want to live my life without regrets, so I must exert my greatest strength in the field where I am best. You once criticized me, saying that I was about to become a low-end project manager. I have kept your criticism in mind for decades. In the field of science, I will leave something that can be passed down for thousands of years, just like Zhong Lei."

After saying that, Ryan began to carefully introduce the core of the solar system rapid transportation network to Chen Feng.

Ryan completed two preliminary designs.

One is the construction plan of this first-generation transportation network.

When the first generation of Dyson membrane is completed around 2200 and mass-energy conversion technology becomes a reality, a large number of ordinary people will become engineers.

This step, using strong ropes to build a framework for the vascular network, requires a large number of workers to complete it manually.

Afterwards, the stars with super quantum intelligence will take over most of the remaining work, controlling large-scale engineering robots with mass-energy conversion functions to repair along the cableway.

Large-scale engineering robots that can produce materials and continuously complete construction only require a small number of manual operators.

According to Ryan's plan, as long as there are enough engineering robots, the first generation of vascular networks will be completed within 2,300 years at the latest.

Ryan's second design is the long-term direction of the vascular network.

The first generation of the solar system vascular network relies on ultra-vacuum and electromagnetic propulsion to achieve a material transportation speed of up to one-third the speed of light.

The second-generation vascular network's orbital trunks will be built in the curvature subspace below the gravitational lines, and can reach up to twenty times the speed of light. The coverage of the vascular network will be expanded to tens of light years, or even hundreds of light years, and can be popularized throughout the Orion Arm.

The third-generation vascular network is built on a foundation similar to Stargate technology. By utilizing the triple space, it can achieve ultra-fast material delivery similar to Stargate transmission, and can even be laid out throughout the galaxy.

As for the fourth generation, it is Ryan's ultimate theoretical goal. It is for humans to use the Grand Unified Theory as the foundation and build their own cosmic-level fast channel that is completely different from curvature and folded space. The ultimate speed of the third-level curvature space of twenty-five thousand times the speed of light is just the basis.
