Earth Era

The reason why Zhao Lan felt pain and self-blame was naturally because he did not come up with a way to separate the maintenance cabin and the hydrogen bomb spacecraft early. If this method could have been thought of an hour earlier, no, just half an hour earlier, the distance between the maintenance cabin and the hydrogen bomb spacecraft would have been extended to more than fifty kilometers, and the calculation is based on the damage to the maintenance cabin at the current distance. In terms of basic points, if the distance can be extended to more than fifty kilometers, then the damage suffered by the maintenance cabin will be completely within the tolerable range.

That's why Zhao Lan feels so self-blame and painful. Because Zhao Lan believed that he had caused the current consequences and that he had ruined everyone's lives. Under this situation, the flash of light that appeared deep in Zhao Lan's soul made Zhao Lan feel like he had grasped a life-saving straw, and he felt that his spirit was suddenly lifted.

Zhao Lan didn't find a specific way to deal with it, but that fleeting flash of inspiration made Zhao Lan realize that the situation was not completely hopeless. I still have a chance to solve this problem.

So...how to do it?

Zhao Lan began to carefully analyze the dilemma he was facing now. Zhao Lan classified the complicated affairs and summarized them one by one according to logical thinking. Finally, Zhao Lan divided all the difficulties he was facing into two.

The first dilemma is how to survive in this damaged maintenance cabin for more than half an hour. Because only half an hour later, the military spacecraft could come to rescue him.

Faced with this problem, Zhao Lan's thinking result was that there was no solution. But just because there is no other way, it doesn't mean that he will not be able to survive this period of time. The air purification circulation system has stopped working, so... can it be sustained for half an hour simply by relying on the existing air reserves in the maintenance cabin? The thermal insulation system has failed and the temperature in the maintenance cabin will drop quickly. So under low temperatures, can he and An Liya survive for more than half an hour?

These are all uncertain. Uncertainty means that you may not necessarily live, but you may not necessarily die either.

The second dilemma is how to send a signal to the military combat spacecraft arriving later so that they can discover themselves.

The only dilemmas Zhao Lan faced at the moment were these two. In the first dilemma, Zhao Lan chose to leave it to luck. Or maybe it’s fate to choose, but the second dilemma won’t work. Zhao Lan must find a way. After the military combat spacecraft arrives, deliver the message to them so that they can rescue you. If the message cannot be conveyed, there will be no rescue. Even if it can survive the rising carbon dioxide concentration and low temperature environment for half an hour, everyone will die.

So the key point of the problem comes here, that is, how to convey information?

Just find a way to deliver the message for help. Everyone has hope of continuing to live. If no way is found to deliver the distress message, everyone will die here.

At this moment, Cruise's lighter had gone out, and complete darkness returned to the maintenance cabin. In this completely dark environment, Zhao Lan's brain was running at high speed.

This is a dark and empty space. Zhao Lan and others were traveling in a maintenance cabin of a hydrogen bomb spacecraft that had lost its power supply. This maintenance cabin has no power and cannot make any autonomous acceleration, deceleration, or course change. This means that Zhao Lan can do almost nothing.

But the flash of inspiration that just appeared made Zhao Lan realize that there must be something he had forgotten, and there must be a way to achieve the purpose of transmitting the message.

Zhao Lan huddled in the corner of the maintenance cabin. Thinking hard about this problem.

How to convey information? How to convey information in this empty and dark universe?

The answer can only be through electromagnetic waves. Radio signals are also a type of electromagnetic waves, but now radio equipment can no longer be used. So, what about electromagnetic waves other than radio signals?

A noun flashed in Zhao Lan's mind. Zhao Lan thought of a word, this word is. visible light.

Visible light can certainly be used to transmit signals. In ancient beacon towers, when a beacon fire was lit, people far away could see the smoke column and get an early warning. From a strict perspective, this was actually the use of visible light to transmit information. Modern lighthouses, neon lights, and signboards can also be counted as examples of visible light transmitting information.

So...how do I get visible light? Don't forget that the lighting equipment in the maintenance cabin is no longer usable due to the loss of energy supply.

Then the key point of the problem comes to the energy supply. Zhao Lan continued to think hard, think hard...and then, it was as if the thoughts that had been suppressed for a long time suddenly exploded. Zhao Lan suddenly thought of a possibility.

This maintenance cabin was also designed and built under the leadership of Zhao Lan, who was familiar with every structure of it. So now Zhao Lan suddenly remembered. There is a small battery installed in the filter module of the air circulation system. To remove it, you do not need to go outside the cabin. This task can be completed inside the cabin. Although the air circulation purification system was destroyed, the small battery was still very likely to be intact. As long as it is removed and connected to the lighting system, will the light be restored in the maintenance cabin? As long as the maintenance cabin can be restored to light and controlled to flash on and off according to a certain pattern, then it is likely to attract the attention of nearby spacecraft. Although the chance of attracting attention is still much smaller than calling directly through the radio, this... is still a hope, right?

After understanding this, Zhao Lan immediately regained his energy. Zhao Lanman said eagerly: "Cruise, Cruise, I have thought of a way for you to try. There is a small battery in the filter module of the air circulation purification system. I want you to dismantle it." Come down and connect it to the lighting equipment. After the military spacecraft comes within a certain distance from us, we can ask for help from the military through visible light!"

Cruise immediately said: "Can it be disassembled in the maintenance cabin?"

"Yes!" Zhao Lan gave an affirmative answer, "You don't need to leave the warehouse to disassemble it!"

Suddenly she had hope again, and An Liya's voice began to become urgent: "Zhao Lan, please point out the location quickly, Cruise, it's time to show off your mechanical genius!"

"Leave it to me." Cruise replied briefly. Under Zhao Lan's guidance, he found the place and started working immediately.

Cruise's fingers are thick and short, but extremely flexible. He completed the disassembly of the battery without using any tools. After completing this task, Cruise immediately opened the cover of the main lighting lamp, then pulled out the wire directly and cut it off.

"I need to make a small transformer device to solve the problem of voltage asymmetry between the battery and the lighting." Cruise said in a low voice, "This will take ten minutes."

"It is expected that the military spacecraft will enter the fifty kilometers around us in fifteen minutes." Zhao Lan also replied in a low voice, "This is the limit distance. In order to prevent the impact of the residual radiation from the hydrogen bomb explosion, they will not get closer. .The exact time they will stay here is unknown, but it is expected to be no more than ten minutes. This is our last chance."

"Okay." Cruise agreed and immediately started busy. Under the operation of Cruise's dexterous hands, a strange-looking thing gradually took shape. It was very rough and messy, and even its lines were simply twisted together without any welding or isolation. , but after the main lighting line was connected to it, the lighting turned on.

Zhao Lan's spirit immediately lifted, but the lights went out the next moment, and darkness returned to the maintenance cabin again.

"What's wrong?" Zhao Lan asked in a low voice.

"This battery has a limited amount of power. It can only support the lighting for one minute at most." Cruise replied, "It was just a test to determine whether it could be used."

"Okay, let's start waiting." Zhao Lan said.

The battery can only support one minute, so naturally Zhao Lan and others are not willing to waste this precious lighting time now. It is most appropriate to turn on the lights after the military spacecraft approaches a certain distance.

So now all we can really do is wait.

"Everyone try to slow down your breathing and don't make big movements, so as to save oxygen. Also, everyone should get together. The temperature is getting lower and lower, and everyone getting together can help keep warm." Zhao Lan said.

So An Liya and Cruz gathered together towards Zhao Lan. Zhao Lan placed the unconscious Zhou Xiaoming in the middle, and the three people who were still conscious surrounded Zhou Xiaoming, trying to warm Zhou Xiaoming's body with their own body temperature.

Under the near-absolute darkness, the passage of time seemed to slow down. It was so quiet here that Zhao Lan could almost hear his own heartbeat and breathing. The heartbeat and breathing seemed to have a strange rhythm. Under the beating sound of the heart, people felt dizzy and wanted to fall asleep.

Then Zhao Lan realized that the carbon dioxide concentration in the maintenance cabin must have risen to a very high level, and he had shown slight signs of carbon dioxide poisoning. This won't work. Zhao Lan knew that as long as he fell asleep, he would never wake up.

So Zhao Lan opened his mouth and said slowly: "Idle time is also idle, let's chat? Anlia, how did you join the adventurer team in the first place? Cruise, what about you? "(To be continued~^~)
