Li Yueqing picked up the water glass, hurriedly took a sip, then cleared his throat and continued: "Your Excellency, the three questions you mentioned are indeed like three mountains in front of us. Pen ~ fun ~ pavilion www.biquge.info but it is not without a glimmer of hope. ”

"Let's start with a brief discussion of a well-established closed ecosystem, which is not only a problem that the Interstellar Migration Project needs to solve, but also the underground city system of the Crisis Defense Systems research team. I believe that if all the experts in biology, ecology and natural environment on the earth work together, it is entirely possible to create a complex, perfect, and recyclable closed ecosystem. ”

"You're right, we can climb this mountain with more effort!" Frank nodded in agreement.

"A stable energy supply is indeed a big problem, unlike the underground city ecosystem, the space castle cannot use the abundant geothermal energy, nor will it be supported by the surface system, the daily consumption of human survival in the space city ecosystem, such as the energy required for lighting and heating, and the use of artificial sun to grow food, vegetables, fruits, etc. Therefore, we must find ways to develop more efficient and reliable energy sources. In the universe, light energy alone will certainly not be able to sustain the functioning of a huge society. Nuclear energy is perhaps our most reliable way to obtain energy at the moment. ”

"Nuclear power!?"

"How can we get so much nuclear fuel unless we can master controlled nuclear fusion technology!?"

"Indeed, the nuclear fusion energy contained on the earth is about 10 million times that can be released by the elements that can be used for nuclear fission, and there are 45 trillion tons of deuterium in seawater alone, which can be said to be an inexhaustible source of energy."

Other researchers also voiced their opinions.

"Therefore, it is imperative that the Earth civilization find a way to overcome the problem of controlled nuclear fusion, otherwise the energy supply of the interstellar migration program will inevitably be greatly challenged." Li Yueqing continued.

"Okay, we won't discuss the other details of nuclear fusion technology for the time being today, and move on to the next question." Frank nodded.

"Space gravity technology is the most critical technology to ensure that humans can survive in a giant spaceship or a space castle in good health. It is also the most difficult technology to solve at present. I'm ashamed to say that I have been working on unified force fields for many years, but there has never been a substantial breakthrough. Li Yueqing said with a regretful face.

"You don't have to mind, this is a problem that even Einstein didn't solve in his whole life." Frank said with a wave of his hand.

"If only Commander Yuan Haochen could find the relevant science and technology in the Alpha Centauri system." Li Yueqing said again.

"You forgot, the premise of our discussion today is that Future didn't find any of the science and technology we needed." Frank reminded.

"Then we can only build a rotating centrifugal artificial gravity system, so that the technical difficulty and engineering volume of the construction of the space city will increase precipitously!"

"Well, if we follow our current scientific and technological strength, even if the space castle can be built as desired, there will definitely be only a very small number of people who can successfully leave the earth in the end."

"The reality is so cruel!"

"Fortunately, this is just hypothetical, and we still have hope in the Alpha Centauri system."

The researchers began to discuss.

"Everyone, let's further refine the plan of the space castle......"

Frank had already made up his mind, and he began to split the work into teams of experts in different fields. Although this is a white lie, it is certainly not his style to come up with a plan that is full of running trains.

This is not that he does not have confidence in Hara's exploration work in the Alpha Centauri system, on the contrary, it is a sign of his strong confidence in Hara's report.

......

At the same time, in the middle of a beautiful island in the middle of a beautiful lake on Earth, stands an old castle full of heroic masculinity.

In the banquet hall of the old castle, a wrinkled Justter was still sitting peacefully by the warm fireplace as ever.

The old-fashioned banquet hall was quiet, save for the sound of the fire flickering and dancing in the fireplace.

Just's eyes narrowed slightly, staring straight at a middle-aged man with a white beard standing across from him.

"I'm sorry, Mr. Just, but our strongholds in Asia and Europe have been wiped out by local government forces."

The middle-aged man with all white hair put his hat on his chest and said in a nervous voice.

"A stronghold? Termination? Be careful with your wording! ”

The wrinkled Justter looked very kind, and the corners of his mouth were raising a faint smile, and he slowly opened his eyes and glanced at the middle-aged man with white hair in front of him.

"I'm so sorry, Mr. Just! I am extremely ashamed of the vulgar and inferior language just now. Seeing Just's smile and kind eyes, the middle-aged man with all white hair quickly bowed down and apologized as if he had seen a ghost, "Our bases in Asia and Europe have been shamelessly attacked by local government forces. ”

"Oh~"

Mr. Just's eyes narrowed slightly, and without saying more, dead silence fell back in the empty banquet hall.

"This ......," asked the middle-aged man with all the white hair, tentatively and softly, "and ask you, Mr. Just, how we are to proceed next, Mr. Just. ”

Still silent, after a long time, Justt opened his eyes, very calm and whispered: chaos, only chaos, we will have more opportunities. ”

"Chaos!?"

The middle-aged man with white hair muttered softly.

"Yes, chaos. Do you understand? ”

Just asked softly.

"Got it, I got it." The middle-aged man with all white hair hurriedly replied.

"Okay, you can step aside."

"Yes! To shatter the Crusaders!! ”

So, the middle-aged man with all white hair quietly turned around and walked through the banquet hall, heading towards the corridor that connected the banquet hall.

As he passed by the portrait of the current owner of the castle at the end of the corridor, Mr. Just.

"Ding~Dong, Dingdong~"

The ungraceful sound of a harp suddenly sounded, easily piercing the quiet castle ballroom and reaching his eardrums.

The middle-aged man with white hair was unconsciously startled, he subconsciously glanced at the portrait of Mr. Just, and then quickened his pace and hurried away from the old castle.

In the portrait, Mr. Just's lips are showing a faint smile, in fact, more like a sneer.
