After a short period of darkness, the two figures had reappeared outside the Ula underground base.
After being ravaged by floods, it looked like a huge battlefield, with broken trees and scattered stones everywhere.
"Go by yourself. If you need anything, you can use your watch to contact me."
"Thank you, commissioner!"
After Ivan took a deep breath, he walked towards the door of the ground passage.
Zhang Bei took a look and then crushed the teleportation crystal core again and returned to his prairie.
The troubles in the underground base are over for now, but there are two more important things in this world.
The first one is the group of saviors. According to their plan, the sun will be restarted in a few days. Although Zhang Bei has no hope for success, he wants to see what's going on with the disappearance of the sun's energy. .
They collected a lot of resources and built a huge fusion bomb. According to theory, the energy released by this thing in an instant is enough to compare with the sun's continuous operation for two months.
If according to their assumptions, the sun itself still has energy, the explosion of this bomb is indeed enough to release the energy of the sun and generate new fusion.
But unfortunately, the real reason why the sun is extinguished is that the huge energy is disappearing, and this plan is destined to fail.
Zhang Bei's purpose was to use some magic to try to see if he could find the reason for the disappearance of the sun's energy.
Energy, like a smile, does not disappear out of thin air, it only transfers.
Based on this conclusion, it should be speculated that something is absorbing the energy of the sun.
Zhang Bei knew this conclusion a long time ago, but he never used magic to observe the sun.
In order to bring the bomb closer to the sun, the rescuers first built a carbon composite protective layer on the outside of the bomb, which was also coated with a white ceramic layer.
Relying on these two materials to withstand temperatures close to two thousand degrees, they can pass through the chromosphere and transition zone and reach the corona.
After reaching the corona, the bomb will rush towards the sun at the fastest speed and detonate using the heat radiation of the sun itself.
This is almost the ultimate that a first-order civilization can achieve. It is in close contact with the sun and can completely absorb all the energy of the sun.
Anyone with a little knowledge of science and technology will know that this kind of technology can only be accomplished by at least a third-order or even fourth-order civilization.
Even though Zhang Bei is now only one step away from breaking through to the second level of transcendence, he still cannot be careless in the face of this threat. He relies on the fluctuating energy of the bomb launched by the savior when it explodes, so he can rely on magic to observe it.
Secretly, he used a Xuanguang mirror to determine the time when the savior would launch the sun bomb, and then moved his perspective to the spacecraft being built.
It has to be said that the two materials Zhang Bei produced can be said to have unlocked the prerequisites for the spacecraft.
The powerful properties of Alloy No. 9 can be used as the main body of a spacecraft, and nuclear fusion is an essential energy source for space navigation.
Although the spacecraft still lacks a weak artificial intelligence, it can be replaced by manual operation.
Compared to the troubles in most underground bases, their progress was smooth.
During the time when the flood came, various large machinery had already begun to build the spaceship according to the design drawings.
The difficulty with the spaceship, apart from materials and energy, is the design.
Although the current AI technology is not as good as weak artificial intelligence, there is still no problem in designing a suitable spacecraft blueprint with the help of supercomputing.
Compared to the savior's plan, which was full of unreliability, the elite group of people who built the spacecraft actually had great hope.
After all, after the earth lost the sun, it could be said that it had completely turned into a desert. It would take decades to recover even with the full set of second-order civilization technology given by Zhang Bei.
If any basic scientific problems are encountered, this time will be extended indefinitely.
In comparison, the certainty of the spacecraft is very high, as long as the spacecraft can successfully navigate in space, relying on a complete ecosystem and strictly controlled family planning.
Using nuclear fusion as energy to provide spacecraft acceleration, a planet suitable for human habitation can be found in up to three hundred and seventy years.
With better luck, this time can even be shortened to within two hundred years.
Although the next few generations may have to spend time on spaceships, the value of a new life planet will definitely far exceed that of the earth.
Zhang Bei silently estimated the progress of the spacecraft manufacturing, and could probably get an idea of the time when civil strife would occur in the spacecraft plan.
The IQ of this group of elites from different countries around the world is far beyond what ordinary people can match.
They all know the fact that the day the spacecraft can successfully take off, the priority pattern will be fixed.
Therefore, the only time they can take action is the day before the spacecraft is built.
At this point, Zhang Bei has figured out the general situation of this world. As long as he continues to pay attention, there will be no problem.
Time passed unknowingly while Zhang Bei was fishing, and in the blink of an eye it was already the last forty-nine days of the countdown.
Zhang Bei withdrew from his cultivation state, pulled up the Xuanguang Mirror and began to watch the savior's actions.
Today is the Savior's plan to restart the sun, and the huge fusion bomb is ready.
From the appearance, this guy is a large rocket, at least in terms of volume, far exceeding any rocket launched in human history.
This thing is something that the 1.3 billion people of the Savior have worked hard to create, and they have extracted resources from various countries.
Coupled with their continuous collection, this huge launch vehicle was finally completed.
The take-off weight of the entire rocket is a full 4,530 tons, a large part of which is fuel.
After all, unlike hanging two satellites in low-Earth orbit, this thing is going to the sun farther away, and it is impossible to reach it without enough fuel.
Millions of people are wearing shoulder straps with the savior logo, standing outside the launch base, watching the rocket that carries their great hope gradually take off in the countdown.
The huge smoke and dust obscured the sight of countless people, and the rocket quickly took off under the operation of the ground command center.
There are 1.3 billion people, including a huge number of scientists. With their capabilities, it is not a difficult task to send a rocket to the sky.
Regardless of the fact that it has been very difficult to get to the sky since humans created rockets, in fact the real difficulty of this thing is to carry people.
Otherwise, if you were to count the satellites in the sky, it would be very difficult to have so many usable satellites surrounding the earth.
