Jon wandered around the Hope spacecraft a bit, and didn't go everywhere.
It was mostly his own living area.
Ella had prepared it for him in abundance.
A huge 20 square meter bedroom with a 1000 inch giant movie screen in the AV room, a kitchen, a game room, a study, a gym, and of course, the essential - a toilet.
A very rich living area.
Of course, in addition to these there is also "a street" made after the Earth, a street that is enough to make it look real, simulating the sky and the ground, but there is no one.
It added up to a total of square meters.
Holding a tablet in his hand, Jon was zooming in on a video.
The view of the video was exactly the scene of Earth.
In 100 years, the Earth had been completely torn apart, and if there had been a one in a billion chance of the original Earth's humans surviving, there was none now.
It had been hit by the moon long ago, and along with it pieces of the moon had been pulled into a long string.
Only tiny fragments are visible in the video.
But each piece of that debris could have been a city, a country, of the original human race, inhabited by dozens and dozens of millions of humans.
And now, there should be millions of human skeletons lying inside.
Jon was inevitably a little despondent.
Ella appeared on a screen in front of him and reminded.
"Jon, we will depart in six months."
"The fragments of the Earth and the Moon are already going to reach the surface of the Sun, and when they impact, that's when the solar system will undergo a huge change."
"By then, we will only be mercilessly destroyed if we are still in the asteroid belt."
It had been 100 years, and it was time for Earth to sink into the arms of the sun.
Jon perked up at that.
"Show me out to the third generation controlled fusion device."
Ella led Jon towards the outside.
Of course, there were spacesuits to be worn.
But compared to 100 years ago, the spacesuit Ella had created specifically for Jon had turned pitch black, with only a thin layer that fit his skin, and although it still had a huge bulb-like hood, it was so much easier and simpler than it had been 100 years ago.
Leaving the spacecraft with his feet on top of the steel frame, Jon realized just how large the view of the outside of the spacecraft he had just seen was.
The platform he was standing on alone was over 200 meters wide and over 5000 meters long.
As he stood here, it was like a tiny mole cricket lying on a piece of a4 paper, or even smaller.
Looking back at the Hope, it was even more shocking.
The dark body of the ship in the dark background is deep and profound, slightly metal reflections to add a hint of cold meaning, it is like a huge beast quietly prostrate, waiting for the awakening.
Not much time.
A burgundy streamlined magnetic supercar parked in front of him, looking somewhat like a Bugatti.
This supercar was not constrained by gravity because it was in cosmic space, and it looked big, six meters long and more than three meters wide.
Jon sat in it very spaciously.
The moment the door closed, the hypercar boosted to 300 kilometers per hour in one second, a five-kilometer platform in just a minute.
Then it entered the surface of the asteroid and took another two minutes to stop outside a huge factory that was 180 meters high and covered an area of over a million square meters.
The factory was numbered A-283.
Ella had set an engineering importance level for the factory, with A being the highest and F the lowest.
Jon entered the factory.
The first thing he saw was a huge device.
The height of the device was more than 70 meters, the diameter was more than 200 meters, and the most striking thing was the transparent ring-shaped device, which was hollow inside, and the flashing and jumping electric currents could be seen.
Each current was as thick as Jon's arm.
"Electromagnetic confinement?"
The controlled fusion device itself needed high intensity magnetism for constraint, and this kind of super-strong magnetism where currents appeared was a bit over the top for Jon.
Just the sheer size of it was enough to illustrate its terrifying performance.
"Jon, the third generation controlled fusion device is now in its final testing phase, please look."
Ella pointed towards that side.
An ear-piercing roar followed, it was as if an oversized fan was turned on blowing straight in the ear, the noise was pulled straight to full capacity.
This was space, and the only reason there was sound was because Jon was standing on the ground, and sound could travel through solids.
Jon jumped up and left the ground at once.
The sound then all but disappears.
Looking again at the controlled fusion device, the entire ring container had been turned into light, it was impossible to see straight.
It was still essentially a Totamak device, called a small sun.
The nuclei of heavy hydrogen "deuterium" and super heavy hydrogen "tritium" are fusing, releasing powerful energy.
This energy is captured in the device as heat, which is then converted into kinetic energy.
It's still "boiling water".
This device was one of mankind's greatest pursuits a hundred years ago.
Controlled fusion means inexhaustible energy.
And Jon and Ella have made this giant leap forward for the entire human civilization.
Shocking!
There was nothing but shock in Jon's heart.
The third generation controlled fusion device was rigorously ignited for thirty-seven tests and began to be loaded.
Jon still couldn't believe it when the huge device was shoved into the spacecraft.
After all, his consciousness was still stuck a hundred years ago.
"Jon, after the third generation controlled fusion device is loaded, the power bottleneck of my mainframe will increase again."
"In a hundred years, my code has gone through 23 rewrites, and I would also like you, one of my creators, to check the code for me."
Ella swiped and pulled at the screen and a large amount of code appeared on the screen in front of Jon.
As a computer engineer, Jon instantly felt sick to his stomach at the sight of the string of code, and especially after seeing the number of lines, he couldn't tense up.
The number of lines of source code - lines!
Despite the dizzying look, Ella was his main safeguard afterward, and Jon scrutinized the code, including the three principles at the bottom.
After all, there were 180,000 lines of code that Ella had written for herself over the years.
The code had gradually gone beyond the level of what human society should be.
Ella's willingness to let him inspect it, presumably because she wanted him to feel comfortable with it, was sideways evidence that Ella had become more human-like over the past 100 years.
It took a month.
"Inspection complete, very ok."
From Jon's perspective, there were no flaws.
"Yeah!"
Virtual Ella jumped up and down in excitement.
And at that moment, the Hope had finally finished installing the third generation nuclear fusion device.
Jon sat in the huge cockpit, the screen around him was filled with scenes from various factories, some robots were still working.
All the things here one Hope ship would not fit.
These things would have to stay here.
"Ella, is it possible for them to escape the solar storm?"
Ella replied seriously.
"It's less than one in a thousand possible, Jon!"
"It's too close to the sun."
Jon sighed.
"At least there's a slight possibility, right?"
"Write them a set of AIs, and if they survive, let them develop on their own."
"This is, after all, where humanity originated."
"Their birth is also an extension of human civilization."
"We are leaving the solar system this time, and we don't know whether we will live or die, we only hope that, if they, the machines, can survive, they can also inherit the human will."
Ella nodded her head, her white hair ruffled, and she also learned to show a sad look.
"Okay, Jon!"
In less than a minute, all the work was done.
"Light the fire, Ella."
"The target remains the planet Beale."
Jon looked through the screen at the factory outside.
He was genuinely unsure if he would ever return from this trip.
"Okay, Solar System Asteroid 001 starport retraction commencing, calipers disengaging, spacecraft departing port, have reached scheduled takeoff position!"
"Target course confirmed, setup complete for optimal course, all magnetic valves open, all electromagnetic thrusters beginning to feed."
"All preparations complete."
"Five!"
"4!"
"3!"
"2!"
"1!"
"Ignition ..."
The spacecraft awoke, a horrific wave of ice-blue heat erupting from the tail that felt capable of melting everything, and a shooting star left the asteroid.
It was, perhaps, a goodbye forever.
On the asteroid, all the robots came out and saluted in the direction the Hope spacecraft had left!
