Sophon spoke up after a brief silence, "We can do that, provided we exchange it for 'Where is the thickness of life?'"
Jiang Yu shook his head, "You should know that those two pieces of intelligence are not equivalent; I can only tell you the specific target of Plan 9 and the detailed implementation process."
Three to four seconds later, Sophon nodded, "Deal!"
Then she added, "We have observed the spacecraft of the Dark Forest Striker, its gravity is comparable to Jupiter's."
Cheng Xin exclaimed in surprise, "The enemy's spacecraft is that big?"
Jiang Yu and Sophon ignored Cheng Xin's question. After delivering the first piece of intelligence, Sophon quietly looked at Jiang Yu.
Jiang Yu started speaking, "Up until now, there have been two interpretations of Plan 9, one is Chief Ji's interpretation while looking at the trees in the yard; the other is Kong Xiang pointing at the ceiling's interpretation."
"Actually, they both represent one meaning: beyond the sky!"
"When Chief Ji was conveying the order to me, his gaze was distant, not looking at the trees, nor the buildings in the distance, but the horizon! Escaping to the horizon is the only salvation!"
"What Kong Xiang pointed to was upward, not the ceiling, but above the roof, space, interstellar!""
"That's right, Plan 9 is an interstellar escape plan!"
Cheng Xin, who had already been surprised many times today, was still not at the end of her astonishment.
When did Jiang Yu have an escape plan? Could the plan have failed?
Sophon went on, "But its volume is not large, and it's extremely agile, approaching the speed of light almost instantly."
Jiang Yu continued, "At the beginning, even the Wallfacer Project was a cover for Plan 9, because at that time, humanity was no match for the Trisolarans. Apart from escaping, there was simply no other road to take.
"The emergence of Teacher Luo Ji's Dark Forest Law was an accident!"
"Over sixty years ago, the first phase of Plan 9 was successful, and as I mentioned before, six fleets I dispatched are still on their way to their destinations.
"They didn't go through the Dark Battle, nor the lengthy reconstruction and resource plundering, so they're faster than Starship Earth."
Sophon continued, "According to our observations, the particle's mass inflation is due to speed, which means the opponent used energy to accelerate a tiny object to near-light speed.
"This requires huge energy, and we speculate this energy comes from the application of dark matter."
Jiang Yu said, "Plan 9 is still ongoing, previously to avoid the strikes from the Trisolarans, and now to avoid the Dark Forest Strike!
"You already guessed the specific implementation, I presume."
Sophon sighed, "If our star system had only one sun, we would do the same."
Cheng Xin anxiously said to Jiang Yu, "We cannot undertake interstellar escape! Human society will collapse! That way, very few people can actually escape! Do you really want to watch ninety-nine percent of people perish in despair?"
Logic suddenly interjected, hinting, "The first phase of Plan 9 did not lead to the collapse of human society, and Jiang Yu himself gave up the chance to escape."
Cheng Xin first released a deep breath, then asked hurriedly, "Can you tell me your plan? I want to join, to help more people escape the Solar System!"
Jiang Yu looked at Cheng Xin, "Didn't Sophon just give a hint? We are like a little bird standing under a Spotlight, so we could go outside the Spotlight."
Logic sighed deeply, "That's also good. The reason humanity has been reluctant to venture out may be because of the ties to our homeland."
Obviously, he had also guessed Jiang Yu's plan.
Cheng Xin started to carefully recall the hint Sophon gave, as well as Jiang Yu's and Logic's words, but she still couldn't figure out what Jiang Yu's plan was.
Sophon then asked, "How can we exchange for the information about the thickness of life?"
Jiang Yu replied, "The technical details of the Material Flow engine and Sophon's technology!"
"Impossible!" Sophon rejected without thinking!
Jiang Yu spread his hands, "You are about to enter the vast Dark Forest, and I know more than you do. Now, I am only interested in the next-stage engine and methods of real-time communication throughout the universe."
Sophon was stunned for more than ten seconds before saying, "We did not kill 171266; he is currently escaping from the Third Fleet fleeing from Trisolaris.
"If you tell us the intelligence we want, we will send him to the Solar System!"
This condition also moved Jiang Yu, no matter what 171266's intentions, the intelligence he provided was of great help for humanity to understand the Trisolarans.
Jiang Yu thought for a few seconds before saying, "Don't send him to the Solar System then, having just fled a Dark Forest Strike, to come to a star system potentially facing a Dark Forest Strike.
"This isn't saving him, it's harming him."
He paused then added, "But I hope you can treat him kindly, give him the best resources and living space.
"For this, I'm willing to provide a key piece of intelligence obtained from the Black Cuboid People, to a certain extent, as important as the intelligence you want!"
Sophon paused for more than ten seconds before saying, "Deal."
Jiang Yu took a deep breath, "The Dark Forest Law that our two worlds have been abiding by is not complete!"
As soon as these words were spoken, both Logic and Cheng Xin felt a chill run down their spines!
Sophon asked the question they all wanted to ask, "Not complete? How can it be incomplete? What part is missing?"
Jiang Yu shook his head, "My Strategic Department is also researching this issue, but for now, we can only be sure that it is indeed incomplete, without knowing what's missing."
Sophon, Logic, and Cheng Xin were sitting quietly, but their hearts were anything but calm!
Logic was most familiar with this feeling, as if peering into the hidden face of the universe, without understanding what he had seen exactly.
After a long while, Sophon finally said, "We feel your sincerity, 171266 will enjoy the same treatment as a Governor until his natural death."
Jiang Yu nodded, "Please convey my thanks to him."
Sophon asked again, "How can we get the information we desire?"
Jiang Yu smiled and said, "I already mentioned my bargaining chip."
It was then that Cheng Xin suddenly realized: Jiang Yu already had the stature to negotiate with the Trisolarans as equals!
In Cheng Xin's mind, the position of the Solar System State was somewhere between the Trisolarans and the PDC.
More advanced than the PDC, but still somewhat inferior to the Trisolarans.
Before coming to Sophon, she had imagined all kinds of ways to extract information, even thought of pleading with Sophon, determined to use any method to gain more intelligence.
But when the time came, she realized that if Sophon didn't want to speak, she wouldn't be able to get anything.
Yet Jiang Yu seemed to have countless chips, trading with the Trisolarans.
