The last human in the universe

Chapter 32 TNT Dynamite
After hearing Chen Feng's narration, Zhao Changxing's heart instantly became hot.He didn't speak, but directly turned on the portable computer, retrieved the relevant data and formulas, and immediately started the calculation.

When the calculation result appeared and completely matched what Chen Feng said, he let out a long breath.He stood up, patted Chen Feng on the shoulder, but didn't say a word.

At this moment, there is no need for words to say more.

Another meeting was called immediately.All adults participated in the meeting either in person or via video.

When Zhao Changxing announced Chen Feng's discovery, and everyone proved it was true through their own verification, long cheers erupted in the conference room.Finally, it calmed down under Zhao Changxing's restraint.

"Let me just say, there is no hurdle that cannot be overcome." Zhao Changxing's expression was still relaxed: "But everyone, don't be too happy. This just means that we have a glimmer of possibility. In the process of realizing this possibility, we are still needed. A lot of hard work has been put in. Moreover, even if we work hard, we may not necessarily be able to reap the ultimate success."

People's expressions gradually became serious.

This is indeed the case.

There are many possible surprises.For example, people did not open enough proper gas outlets for this asteroid, which may lead to substandard reaction force and lead to mission failure.It is also possible that the asteroid's own structure is not stable enough, which affects the gas venting, etc. Any accident will lead to final failure.

This is just a possibility.

"Of course, even if it's just a possibility, it's worth all our efforts. But we have to prepare with both hands. On the one hand, try our best to change its trajectory, and on the other hand, continue to implement the relocation plan! "

"Chen Feng, Qian Yue, Zhao Ye... the five of you, and me, we are responsible for making a feasible project plan. The rest, continue to implement the relocation plan!"

"Yes!"

Under Zhao Changxing's discussion and calculations led by Chen Feng and the others, a feasible project plan was quickly formulated.

The only way to "open" a proper gas release channel on this asteroid is blasting.It is unrealistic to open it through manpower and machinery.One is that there is not enough engineering force, and the other is that there is not enough time.

In the case of explosion, the nuclear bomb is ruled out first.Because at the moment people cannot build a hydrogen bomb or an atomic bomb.

Fusion generators exist, of course, but they simply cannot be converted into hydrogen bombs.Even if it could be retrofitted, people would not choose to do so.

It is so precious and is the main source of energy at this stage.Nobody can afford to lose a single fusion generator.

Nuclear bombs are not enough, so only chemical explosives are left.After analysis and screening, people finally selected the explosive trinitrotoluene, also known as TNT explosive.

In addition to the mature technology, relatively simple preparation and considerable explosive power, this kind of explosive also has one of the most important advantages: it has three nitro groups in its molecule as the oxidant, and it can explode without supplementing oxygen from the outside.This means that people only need to make a container and put it and the detonator in it, and then throw it on the asteroid to detonate remotely. Except for a set of simple constant temperature equipment, there is no need to get the rest The environment maintains equipment, and there is no need to carry other materials.

The location of the explosion has also been determined.

During this period of time, people have observed the geological composition and mass distribution of this asteroid in as much detail as possible, confirmed several geological weak points, and confirmed that even with the power of chemical explosives, it is enough to achieve the purpose of opening the gas channel .Combined with the asteroid's rotation rate, forward orbit and other data, it is easy to calculate which location to choose as the detonation point.

Then... the next thing to do is to produce explosives that meet the quality standards and are in sufficient quantity.

Just use a little too much.Through Xiaoxi's modeling and simulation, it was confirmed that the detonation point should be divided into three different places, and 1.2 tons, 0.8 tons, and 0.72 tons of TNT explosives should be placed in each place, and detonated at an interval of 5 milliseconds, in order to create a suitable gas channel.

This is a total of 2.72 tons of TNT explosives.

Creating that many dynamites is more difficult, but should be doable.

"Walk."

Without the slightest hesitation, Zhao Changxing immediately led the engineering team under him to start making explosives.The rest of the staff are still carrying out the relocation plan, bringing all kinds of precious materials to the Tinder spacecraft.

To produce so many explosives, the raw material reserves in the current chemical plant are obviously insufficient.There was no other way, Zhao Changxing and the others had to drive the space vehicle to continue running on Sedna, collecting raw materials and minerals everywhere.Moreover, making this thing is very dangerous, and it may explode if you are not careful.And, although the principle is simple, the specific operation process is much more complicated, and the combination of various factors makes the production process much slower.

"Let's do it 24 hours a day."

Zhao Changxing immediately made a decision.He divided the people here in the chemical plant into three groups, and each group worked for 8 hours, producing 24 hours a day, and must complete the task before the time window came.

The tasks are heavy and the time is tight. You must concentrate on your work and make no mistakes.Moreover, during this period of time, wartime control measures were implemented, and food was distributed regularly and quantitatively, which made this task even more difficult.

But none of those who carried out the task complained.Just like the people who carried out the relocation plan also didn't complain because of the toil and fatigue.

In extreme moments, everyone sacrifices part of himself in order to seek greater gains for the collective, which in turn allows individuals to benefit more. Everyone understands this truth.

And it seemed that they were aware of the busyness and fatigue of the adults. Although the 100 fourth-generation children did not understand what happened, they seemed to be more obedient and sensible.This makes adults see it in their eyes, feel more relieved in their hearts, and work more actively.

Time passed slowly, and when there were still about 18 days before the moment of impact, three parts, totaling 2.72 tons of TNT explosives, were finally produced as scheduled.The remote-operated electronic detonators and explosive containers took another two days, so with 16 days to go, it was finally finished.

The relocation work is now coming to an end.In plantation base No. [-], the last round of crops was fully harvested and no new seeds were sown.Various automated planting equipment also began to be dismantled and brought to the Tinder spacecraft, and even various gases were recovered.Here at the No. [-] comprehensive base, all livestock, poultry, and fish were slaughtered, and they were also taken into space to avoid possible disasters.

Zhao Changxing and the others drove the Falcon [-] and [-] spacecraft to the asteroid with three explosives.At the detonation point that had been measured in advance, with the assistance of some tools, the three explosives were successfully placed in different positions.

After a final check to confirm that there was nothing missing, Zhao Changxing and the others finally left here.

At this moment, there are still 14 days before the moment of impact.

Change the time window period of this asteroid, from the seventh hour to the fifth hour before it hits the Sedna star, that is, when it is 7000-10000 kilometers away from the Sedna star.Before reaching this window period, the tidal force is too weak to provide enough heat for its interior to achieve sufficient pressure.After this window period, the reaction force of the gas jet will not be enough to push it to change the orbit sufficiently.

So, while the final finishing touches were being carried out on the relocation work, people began to wait in the crowded Tinder spaceship.

All materials that can exist in a vacuum are placed outside the spacecraft.Only materials that must be stored in a specific environment will be placed in the cabin.But even so, the cabin was still extremely crowded.Most people don't have a fixed place to rest, but can only rest on the ground in the cabin.Meals also need to be done in batches.

Fortunately, the life support equipment of the Tinder spacecraft is still sufficient, so people are not in danger of hypoxia.

Time passed bit by bit, and the distance between the asteroid and Sedna's star was getting closer and closer.When the asteroid that was originally marked red in Xiaoxi's simulation screen suddenly turned green, everyone knew that the window period had finally come.

But Zhao Changxing did not press the detonation button.He is still waiting.

On the asteroid, the crack is still ejecting gas to the outside world day after day.But with the passage of time, its injection volume also began to increase slowly.

And this means that the pressure inside it is gradually increasing.

When the relevant observation data was captured by the instrument and sent back to the Pyro spacecraft, people became excited again.

Everything is as it is in the computer simulation!The pressure inside it was indeed enhanced by the gravitational tidal effect of Sedna Star!

"Then, it is now!"

Zhao Changxing resolutely pressed the detonation button.
