Earth Era

The reason why Zhao Lan felt pain and self-blame was naturally because he didn't figure out a way to separate the maintenance cabin from the hydrogen bomb spacecraft. If it can be an hour earlier, no, as long as this method is thought of half an hour earlier, the distance between the maintenance cabin and the hydrogen bomb spacecraft will be extended to more than 50 kilometers, and the calculation is based on the damage to the maintenance cabin under the current distance. From the base point, if the distance can be extended to more than 50 kilometers, the damage suffered by the maintenance cabin will be completely within the tolerable range.

That's why Zhao Lan is so self-blame and painful. Because Zhao Lan believes that he caused the current consequences, and that he ruined everyone's lives. Under such circumstances, the flash of light that appeared in Zhao Lan's heart made Zhao Lan feel as if he had caught a life-saving straw, and felt that his spirit was lifted all of a sudden.

Zhao Lan didn't find a specific way to deal with it, but that flash of aura made Zhao Lan realize that it wasn't a complete desperation. I still have a chance to solve this problem myself.

So... how exactly?

Zhao Lan began to carefully analyze the current predicament. Zhao Lan sorted out the complicated affairs and summarized them one by one according to logical thinking. In the end, Zhao Lan divided all the dilemmas he was facing into two categories.

The first dilemma was how to survive for more than half an hour inside the damaged repair bay. Because only after half an hour, the military spacecraft may come to rescue itself.

Facing this problem, Zhao Lan thought that there was no way. But it doesn't mean that you can't survive this period of time. The air purification and circulation system has stopped working, so... can it last for half an hour simply by relying on the air reserve in the existing maintenance cabin? The insulation system has failed, and the temperature in the maintenance compartment will drop quickly, then below the low temperature. Can you and Anlia last for more than half an hour?

These are uncertain, and uncertainty means not necessarily living, but not necessarily dying.

The second dilemma is how to transmit signals to subsequent military combat ships. Let them find themselves.

There are only two dilemmas facing Zhao Lan at the moment. The first dilemma, Zhao Lan, chose to leave it to luck, or fate to choose. The second dilemma does not work. Zhao Lan had to find a way to send a message to them after the arrival of the military's combat spaceship, so that they could rescue him. If the information cannot be transmitted, there will be no rescue. Even if the carbon dioxide concentration continues to rise and the low temperature environment can last for more than half an hour, everyone will be greeted by death.

So the key point of the question comes here, that is, how to transmit information?

Just find a way to deliver the distress message. There is hope for everyone to continue living. If there is no way to deliver the message for help, everyone will die here.

At this moment, Cruise's lighter has been extinguished, and complete darkness has once again returned to the maintenance cabin. In this completely dark environment, Zhao Lan's brain was running at a high speed.

This is a dark and empty space. Zhao Lan and the others were in the repair cabin of a hydrogen bomb spacecraft that had lost its power supply. This maintenance cabin has no power and cannot do any autonomous acceleration or deceleration or change of course. This means that Zhao Lan can hardly do anything.

But the little light that just appeared made Zhao Lan realize that something must have been forgotten by him, and there must be a way to achieve the purpose of transmitting information.

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

How should the information be conveyed? How to transmit 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 the radio is out of service. So, what about electromagnetic waves other than radio signals?

A noun flashed into Zhao Lan's mind, and Zhao Lan thought of a word. The word is, visible light.

Visible light can of course be used to transmit signals. In the ancient beacon towers, the beacon fire was ignited and people in the distance could see the smoke column and get an early warning. Strictly speaking, this also belongs to the use of visible light to transmit information. Modern lighthouses, neon signs, and signs can also be counted as examples of visible light conveying information.

So... how do you get visible light yourself? Don't forget that the lighting equipment in the maintenance bay is out of service 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. As if the long-suppressed thoughts suddenly exploded, Zhao Lan suddenly thought of a possibility.

This maintenance cabin was also designed and built under the leadership of Zhao Lan. Zhao Lan is familiar with every structure of it. So now Zhao Lan suddenly remembered that a small battery was installed in the filter module of the air circulation system. You don't need to go outside the pod to remove it, you can do it inside the pod. Although the air circulation purification system was destroyed, the small battery is still very likely to be intact. As long as it is removed and turned on to the lighting system, will the light be restored in the maintenance compartment? As long as the maintenance cabin can restore light and control it to flicker on and off according to a certain rule, then it is likely to attract the attention of nearby spaceships. While the odds of getting attention are still much smaller than calling directly over the radio, it's... a hope after all, isn't it?

After realizing this, Zhao Lan immediately recovered his spirits. Zhao Lanman said eagerly: "Cruise, Cruise, I have come up with a solution that you need to try. There is a small battery in the filter module of the air circulation purification system. I want you to disassemble it. Come down, then connect it to the lighting equipment, and when the military spaceship comes within a certain distance from us, we can ask the military for help through visible light!"

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

"Yes!" Zhao Lan gave a positive answer, "It doesn't need to be out of the warehouse to disassemble it!"

Suddenly there was hope again, and An Liya's voice became hurried: "Zhao Lan, hurry up and point out the location, Cruise, it's time to show your mechanical genius!"

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

Cruise's fingers are thick and short, but extremely flexible. He did not use any tools to disassemble the battery. After doing this, Cruise immediately opened the cover of the main light, and then pulled out the wiring and cut it off.

"I need to make a small transformer to fix the voltage asymmetry between the battery and the lights," Cruise whispered. "It will take ten minutes."

"It is expected that the military spacecraft will enter the 50-kilometer range around us in 15 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 definitely not come closer. The exact amount of time they will be here is unknown, but it is not expected to exceed ten minutes. This is our last chance."

"Okay." Cruise agreed and immediately started busy. Under Cruise's dexterous hands, a grotesque thing gradually took shape. It was rough and messy, and even its lines were simply screwed together without any welding or isolation. , but after the wiring of the main light was connected to it, the light turned on.

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

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

"This battery has a limited amount of power, and it can only support the lights for a minute at most." Cruise replied, "I was just doing a test just now to see if it can be used."

"Okay, let's wait." Zhao Lan said.

The battery can only last for one minute, so Zhao Lan and the others naturally refuse to waste this precious lighting time now. It is the most appropriate way to turn on the lights after the military spacecraft has approached a certain distance.

So now really just have to wait.

"Everyone try to slow down their breathing~www.readwn.com~ Don't make big movements, so as to save oxygen. Also, let's all get together, the temperature is getting lower and lower, everyone gathers together to help keep warm." Zhao Lan said.

So Anlia and Cruise gathered together to Zhao Lan. Zhao Lan put Zhou Xiaoming, who had passed out in a coma, in the middle, and three people who were still awake surrounded Zhou Xiaoming together, trying to warm Zhou Xiaoming's body with his body temperature.

In the near-absolute darkness, the passage of time seemed to slow down. It was very quiet here, so quiet that Zhao Lan could almost hear his heartbeat and breathing. The sound of the heartbeat and breathing seemed to have a wonderful rhythm, which made people feel dizzy and dizzy under the sound of the heartbeat and wanted to fall asleep.

So Zhao Lan realized that the carbon dioxide concentration in the maintenance cabin must have risen to a very high level, and he had already shown signs of mild carbon dioxide poisoning. This will not work, Zhao Lan knows that as long as he sleeps, he will not be able to wake up.

So Zhao Lan opened his mouth and said slowly: "Idle is also idle, let's chat? An Liya, how did you join the adventurer team? Cruise, how about you? To be continued)
