A huge turbine was tilted at the top of the entire space, occupying his field of vision. A dark red laser light curtain was lit around the turbine, similar to the one on the outer city wall. An Zhe knew that this was one of the human defense weapons. Once an object tried to force its way through, an alarm would be triggered immediately.
Looking through the iron teeth of the turbine, An Zhe saw the sky outside, where the aurora was still shining. This place was connected to the outside world. He realized that this was the air inlet of the ventilation system. After the turbine was started, the air from the outside would be continuously drawn in and transported to the pipes in all directions.
An Zhe retracted his gaze and looked forward. In the center of this cylindrical space, there was a rectangular metal workbench - perhaps the operating table of the entire system. He walked up to it, but found that it was not the case.
On this metal table, three rectangular boxes were welded. With the help of the light, he could see the mottled handwriting next to the boxes, as if it was plated.
An Zhe leaned over slightly, wiped off the dust and rust, and saw the dense handwriting clearly.
- A letter.
"To those who come after me:
Kang Jinglan is the person in charge of the construction of the ventilation system of our northern base. The ventilation system took one year to design and nine years to build, with a cost of 110 million yuan per kilometer.
Opponents once suggested delaying the construction period because of the difficulty of base construction and the huge amount of manpower and material resources consumed. However, after discussion, we believe that if the geomagnetic weakening continues to deteriorate, the human economy will inevitably collapse within ten years, and within fifty years, the surviving humans will inevitably completely lose their heavy industry research and development and production capabilities, and all production data and scientific research focus will be tilted to the medical field. We have no choice but to do so. There is time.
Fortunately, this year the underground ventilation system was successfully built together with the ground base. From now on, my fellow human beings can live in the strict protection of the base. This is the only thing that comforts me. Despite the strict protection of cosmic radiation, I still suffer from multiple cancers and immune diseases. I asked the base to bury my ashes in the core of the ventilation system, so that every time an engineer enters the system for maintenance, I can know that the base is still safe and the great human species still exists.
May you have a bright future.
Sincerely,
Salute
June 2030. "
This is the ashes.
Therefore, this box contains a former human body, a grave, and these remaining handwritings are letters left by this human to future generations, perhaps it is more appropriate to call them epitaphs.
An Zhe looked to the side and saw a box of almost the same shape on the side, with the bottom welded to the table. There was a letter with the same tone on the side.
"To Mr. Kang Jinglan, to future generations:
I am Liao An, the person in charge of the ventilation system engineering maintenance of our northern base. The ventilation system is inspected every six months and overall maintenance is carried out every two years. It is currently operating in perfect condition.
As Mr. Kang expected, the weakening of the geomagnetic field did not improve, but completely disappeared in December 2030. Fortunately, the artificial magnetic pole project was successful, and the earth was once again protected by the magnetic field, and humans no longer suffered from diseases due to radiation exposure. Unfortunately, cosmic radiation caused bacteria, fungi, and viruses to infect and mutate, and humans ushered in an unprecedented catastrophe. As a survivor of the catastrophe, I witnessed the contraction of the human survival area, the collapse of the economic system, and the gradual loss of industrial capacity. The base invested all the remaining production capacity of mankind in In the military industry, the construction of military bases and the expansion of bases, a steady stream of guns, ammunition, nuclear weapons, aircraft, armor and tanks were produced. I don’t know what the base’s intention is, and I don’t know whether this behavior has accelerated the depletion of human resources. I can only hope that the base has other far-reaching intentions.
In this catastrophe, I was unfortunately infected with deadly bacteria. When my life was about to end, I still felt endless panic about the future of the base, so I chose to be buried here with Kang Xian, waiting for an engineer to report safety.
May you have a bright future. "
Sincerely,
Salute
November 2052. ”
Then came the third urn and epitaph.
“To Mr. Kang Jinglan, Ms. Liao An, and to those who come after:
I am Yang Ye, the person in charge of the ventilation system engineering maintenance of the Northern Base. The ventilation system is inspected every six months and overall maintenance is carried out every two years. It is currently operating in perfect condition.
I must tell the two seniors that at this time, the ventilation system no longer exists as one of the countless infrastructure facilities in the base, but has played an incomparably glorious role in the cause of protecting human safety. In 2053, the global biological mutation began. The human base, with the army as the main force and civilian mercenaries as auxiliary forces, was involved in a grand defense war. In the absence of resources and industrial construction capabilities, the solid military base and powerful military weapons left to us in the last generation played an unimaginable role, ensuring the safety of the remaining humans. The ventilation system was transformed into one of the defenses of the main city of the base, protecting people from the invasion of insect monsters.
At present, the northern base is still safe, and the military and mercenary teams continue to bring back monster samples from the outside world, and recover scientific research equipment, biological data and other necessary materials from the human abandoned city. The base's scientific research focuses on the study of infection principles and the reproduction of human populations. The former has not yet found a direction, but the latter has been initially conquered. A large number of new lives have arrived, and the population has begun to recover. Although the environment is still harsh, I believe everything will get better.
I died of a happy old age disease under the protection of the base.
May you have a bright future.
Sincerely,
January
2104. "
An Zhe finished reading carefully, and then looked to the side. It was empty, without any other boxes. 2104 was already a very distant year. Perhaps an engineer would lie here after his death, and the tombstone would tell the story of a recent development, the fall of the outer city, or something else.
At this moment, loud sobs sounded from all directions, and the mighty night wind blew in from the air inlet. An Zhe shuddered. The strong wind was like an irresistible torrent, making it almost impossible for him to open his eyes - he put his elbows in front of his eyes to resist the strong wind and lowered his head slightly.
At this moment, he suddenly felt a pain in his body.
A piece of snow-white mycelium floated in the wind, in his afterglow, and the white shadow flashed slightly, and disappeared in an instant.
An Zhe turned around suddenly, and the white mycelium he had left to mark the route was only dragged out a short section on the ground, trembling in the wind. The strong wind broke his mycelium, and no one knew where the broken part was blown away by the wind.
His pupils shrank, and he looked in the direction he came from, and saw two dark holes lined up side by side, exactly the same.
