Almost none of the scientific researchers at Shenzhen Aviation Research Institute 3 and 103 were infected. After the outbreak of the zombie virus, they were transferred to the army base along with their equipment and people, and a mobile satellite contact station was quickly established.

From the time it started to rain to now, they have been working non-stop for nearly 48 hours, and no one has chosen to give up.

During the previous rain, experts from all disciplines predicted that there would be abnormalities, and then bacteria, medical research institutes, and laboratories jointly tested the rainwater.

The first test did not detect any virus, but relevant experts are worried and still remind everyone not to be careless. Try not to drink tap water or take a bath until the second test result comes out.

The second test was conducted in all biological research institutes and laboratories across the country at the same time. Before the official test results came out, a zombie wave broke out.

The order of the world was out of control overnight, the network was interrupted, communication signals were interrupted, the power system was gradually paralyzed, and traffic was stopped.

The family members of some scientific researchers, like ordinary people, were infected and died during this unexpected virus outbreak. The scientific research experts who were lucky enough to survive have been working non-stop after being transferred, hoping to curb the spread and mutation of the virus as soon as possible.

Researchers at the Institute of Communications and Aviation Research, under the command of the central government since the virus outbreak, have been trying various methods to restore communications.

Thanks to their efforts, there are currently 13 provinces and more than 80 urban areas with local governments that have established ties with the central government.

No one gives up saving others, and no one gives up saving themselves.

The Aviation Research Institute built in Shenzhen moved important personnel and equipment as soon as the rain stopped to maintain smooth communication with the headquarters and the central government.

Due to the abnormal influence of the earth's magnetic field, only three communication satellites in orbit can still transmit signals intermittently and provide necessary communication networks. The rest have no response at all, and it is impossible to determine whether they have been damaged.

Communication satellite signals are unstable, and some signal base stations on the ground have completely failed due to the influence of magnetic fields.

In order to complete the rescue and resettlement of survivors before the temperature rises to a level that the human body cannot tolerate, the signal transmission function of the satellite must be restored as soon as possible.

Yuan Jin is not very sure that he can use his own technology to change the satellite signal transmission channel.

This world is set in the year 2210, 192 years after the earthly world.

Walking outside the satellite communication center, she showed the pass written by the commander to the soldier in charge of the center's security and anxiously entered.

Seeing the data on the large screen of the signal transmitting and receiving equipment, she frowned deeply again. The technological level of this world was comparable to the high-tech small world she had been to before, and her own level was similar to that of these scientific researchers.

After watching it for a while, Yuan Jin pointed to a set of data on the screen and asked, "Is this a fault code sent back by the satellite?"

The code shows that the satellite signal band is subject to strong magnetic interference, and the microelectronic band is the most serious, and cannot be repaired by itself.

The microband is a commonly used band for satellite communications.

"Colleagues at the launch center are trying to repair it, but the effect is not very satisfactory." The researcher glanced at her and continued to explain, "The signal that can be received currently is very unstable, and the interruption time is not certain. It may be affected by the rotation of the earth.

There are times when the signal strength is very high and times when there is zero signal."

Yuan Jin pursed her lips, pulled out the chair next to her, sat down, picked up the data sheet on the table and opened it.

The earth is constantly rotating, and the signal strength continues to increase and decrease with the earth's rotation. It can barely maintain a satellite phone and receive signals within a fixed period of time.

After reading all the data carefully, she took a pen and wrote a set of codes and pushed it over, "If you can contact the satellite launch center, let them try to change the band and use long wave and microwave neutralization to send signals."

The scientific research expert took her code and looked at it for a while, then shook his head regretfully, "The center has already tried this method, but the connection cannot be established."

Tried it... Yuan Jin closed his eyes, frowned and searched in his memory for how to deal with the situation when the satellite signal was interfered by strong magnetic interference in the small high-tech world.

"We and the center have probably tried all the methods you can think of." The researcher raised his hand and patted her shoulder. "We also hope to restore the signal immediately. Once the signal is restored, the more survivors we can save."

"

The temperature has been rising.

In previous years, the highest average temperature in Shenzhen in February was only 20 degrees. Now the temperature has reached 25 degrees and may continue to rise tomorrow.

High temperatures will speed up the decomposition of corpses, and there are corpses everywhere in the city. Even if there are 100,000 people to clean up and disinfect them, they cannot dispose of all the corpses before the temperature exceeds the human body's endurance.

However, the total population of the three surviving citizen resettlement sites in Shencheng is less than 60,000, and most of them are women, children and the elderly.

The other survivors had already escaped as soon as they discovered the abnormality.

Where can they escape? In just a few hours, the biochemical troops have found more than a dozen meteorites with strong radiation. The suburbs are vast and sparsely populated, so the search will become troublesome, and the lethality of the mutated zombies will be even more terrifying.

"I know." Yuan Jin nodded, and a set of codes from the center popped up on the device screen, asking all scientific research institutes that can receive the signal to try it.

"The center has lost contact with the satellite. The work will be continued by the scientific research institute that can receive the signal. It can be regarded as a relay." The scientific researcher explained to Yuan Jin again, "Now it is our turn to receive the signal. You can take a look first."

Will get other information."

She didn't know where this little girl came from. Seeing that she could write codes by looking through data, she must be a colleague from another institute.

Yuan Jin responded and moved to the side, picked up the mouse of another computer, and unlocked the screen.

The code sent by the center cannot repair the satellite's failure, nor can it maintain stable signal transmission.

Entering the system page of the control center, she looked at the list of provinces and cities with which contact had been established, as well as the satellite signal liaison branches of each province and region, and an idea flashed in her mind.

Communication satellites receive strong magnetic interference, causing signal instability. They can try to add communication functions to other satellites.

After making up her mind, she flipped through the work records and found that the staff of the National Aviation Center had already carried out a relay to crack the crack and quickly opened the crack record.

Among the satellites in orbit, in addition to the satellites of the country, there is also a surveillance satellite launched by the country that was once the most powerful and is now half-dead.

Domestic in-orbit satellites have tried to add communication functions, but unfortunately they have not been successful.

A few minutes later, she locked on the satellite responsible for monitoring the orbit and typed a line of code for ground contact control.

"The satellite is designed to be the most high-tech complex in the world. It is difficult to establish ground contact without a control center. Moreover, the main job of this satellite is to monitor various military and civilian facilities in our country." The researchers were knocking.

Code said to Yuan Jin, "There is a group of staff at the center who have been trying to invade this satellite since the zombie virus broke out."

"Well, I have obtained the permission." Yuan Jin's hands typed out the control code as quickly as possible and set the communication band code. "The equipment and technology of the satellite are indeed advanced, but they forgot to use the highest technology in the control system.

.I looked at the center’s cracking records and found that the direction was wrong.”

"Did you gain control of Shining?" the researchers exclaimed in disbelief, "So quickly?"

As soon as she spoke, everyone in the center looked towards Yuan Jin.

"I got it, here are a few people to help me." Yuan Jin ordered. "One group is responsible for notifying our country's ground communication center to prepare to receive new satellite signal bands and open up communication channels. The other group is responsible for clearing the original codes of the satellites.

Replace it with our control code."

Everyone in the communication center started to move and instantly divided into three groups.

One group continued the work assigned by the center, and the other two groups, together with Yuan Jin, accelerated the speed of controlling the shine.

At the same time, good news came from the biology laboratory, and the results of the experiment on how to make tap water drinkable came out.

At temperatures of minus 15°C, zombie viruses will lose their activity and decompose in water. When encountering high temperatures, zombie viruses that have lost their activity cannot be resurrected.

In order to ensure the safety and reliability of the experiment, the laboratory decided to conduct verification experiments again, and hoped that the communication center would spread the news to other provincial scientific research institutes and biological laboratories.

At 4 o'clock in the morning, satellite communication signals were sent and received stably without any pauses.

All the scientific researchers hugged each other, crying and laughing.

After the signal was opened, the commander, along with the secretary of the municipal government and other leaders, came to the communication support center and contacted the central government to report on the current rescue and resettlement situation.

The central government agreed that all survivors in the deep city should enter the underground city first to avoid further deterioration of the environment and cause more casualties.

At the same time, an order was issued to order the Shencheng post-disaster rescue and resettlement headquarters and establish a national rescue center to carry out rescue operations in surrounding provinces. Arrange rescue work in provinces, regions, and cities with open communications to ensure that no survivor is missed.

The commander hung up the phone and subconsciously glanced at Yuan Jin, who was surrounded by scientific researchers, feeling excited.

The communication signal across the country has been opened up, and the rescue work must be implemented as soon as possible. It is most suitable for her to direct the rescue work. The rescue in the afternoon not only saved people, but also organized the materials in an orderly manner.

The remaining people are responsible for moving various production equipment, and the survivors enter the underground city and strive to restore people's livelihood in the shortest possible time.

As long as you are alive, there is hope to rebuild your home.

After a short celebration, everyone quickly sat back and began to use the satellite network and unite all the communication researchers in the country who could be contacted to restore the domestic ground network and communication signals.

Based on the previous work of the laboratory, Yuan Jin wrote a program to classify communication signal recovery on the ground. Special signal receiving channels were set up and corresponding numbers were set up for seeking help, finding relatives, supplying supplies, rescue arrangements, etc.

Ordinary mobile phones cannot be used, but satellite phones can.

The rescue call channel will be opened first, and then opened according to work needs, so that all survivors can find their families.

"The signal base station on the ground is affected by the abnormal magnetic field and can recover to 70% at most." After reading the program written by Yuan Jin, the leader of the signal assurance team said with a wry smile, "Satellite phones are not standing phones and are rarely used by everyone."

"Some mobile phones have built-in satellite phone modules, which can notify one survivor and contact the second and third ones." Yuan Jin smiled at him and continued, "How will you know if it works if you don't try it.

"

The other party was stunned for a moment and couldn't help but smile, "Let's work hard together."

Others heard that they were going to try, contact the survivors through mobile phones with built-in satellite phone modules, and quickly joined.

The news spread to other provinces where communications had been restored, regional signal support centers, and aviation research centers. All experts familiar with the field joined in, and the team gradually grew.

With more people and greater strength, ground communication quickly returned to 50%, and then slowly rose to 70%.

After several hours of hard work, the domestic communication recovery level stabilized at 75% at 9 a.m. the next day.

All base stations across the country that can be contacted simultaneously send this text message to mobile phones with built-in satellite phone modules: Hello, this is the National Communications Center, and the country has not given up on you. After receiving the message, if you need rescue, please dial 110. The country is with you.

exist.

The system quickly received the call for help and accurately located the location of the caller.

Yuan Jin stood up and stretched his limbs. He realized that the commander and secretary had been looking at him, and he couldn't help but feel nervous, "Did something happen?"

"According to the detection of the meteorological team, the oxygen content in the air is gradually decreasing and the temperature is rising steadily." The commander motioned for her to go out and said as he walked, "Last night, the rescue team followed your instructions and continued to search the city and rescued them again.

500 survivors. The central government ordered us to set up a national rescue center and immediately rush to the rescue of brother provinces after completing the rescue in the province."
To be continued...
