A single snow-white hypha reached out and gently rested on the surface of the wire mesh. Then it made its way inside through a tiny chink in the metal lattice.
It was safe, at least at this point. There were no lethal weapons, only the barrier of the lattice.
After the first hypha went through the three layers of the lattice barrier to the other side, the remaining hyphae moved forward as well. They gathered together, and because they were so soft and flexible, they appeared to be almost liquid. The snow-white tide was pervasive as it penetrated the three layers of wire mesh and then recombined behind them. A pipe leading forward appeared in An Zhe's perception. The pipe was smooth overall, but spots of rust were beginning to appear in some places. The smell of rust spread, resembling the smell of blood. Wind was blowing in from the end of the pipe.
An Zhe proceeded forward. His hyphae stuck to the pipe walls like tentacles as he smoothly flowed ahead. This pipe was straight, and after turning at a right angle, it was still a straight path. He continued, and a four-way intersection appeared up ahead. A horizontal and slightly wider pipe was connected to the pipe he was currently in.
The wind got stronger, and the direction of the airflow was also very complex, indicating that this massive pipe system was like a winding maze.
An Zhe briefly hesitated on the spot. Then he extended one long hypha, leaving it in the pipe before he continued moving forward—although Lu Feng thought he wasn't smart, An Zhe felt that he couldn't be considered stupid either. He decided to mark his path with this hypha. That way, no matter where he went, he could make his way back via the same path by following this hypha.
After making this decision, An Zhe felt much more at ease. He went straight through the four-way intersection, proceeding in the same direction as before. After another right-angle turn, there was a faint light up ahead.
An Zhe came to the light's source—another vent. The familiar news broadcaster's voice was playing. Predictably, he had come to the vent in someone else's home.
"Over the course of a month, the Main City has recalled a total of twelve thousand mercenaries from the outside and formally entered a recovery period. In the expected ten-year recovery period, the Main City's research power will be entirely invested in the investigation of the source of infections..."
"Tap tap tap." There came the even sounds of knocks on the door.
An Zhe had entered by mistake in the first place. He didn't intend to pry into other humans' secrets, so he planned to leave, but then he temporarily gave up on the idea.
There was the sound of a door opening.
"Colonel Lu." A female voice rang out, its tone very crisp.
Colonel Lu.
This was Lu Feng's room.
An Zhe surreptitiously emerged from the vent and moved outwards a bit so that he could hear more clearly, for he was indeed somewhat curious about Lu Feng's life.
Then he heard a familiar cold voice. "Hello."
"Hello, Colonel Lu. I am a staff member of the Garden of Eden's twenty-first floor."
The Garden of Eden.
An Zhe pricked up his ears—or he would have if his current form had such things.
"What do you want?" Lu Feng asked.
"It's like this." The woman smiled. "Firstly, congratulations on your return from the Outer City, Colonel. Secondly, I'm asking on behalf of my superiors if you have any desire to donate sperm to the Garden of Eden at present."
Lu Feng's reply was very succinct and heartless. "No."
"That is truly regrettable. If you are interested in the future, please contact us. Your genes are extremely outstanding, so if they cannot be put to effective use, it is a loss for the entire base."
"Thank you." Lu Feng's tone was not softened by her praise. He said, "Is there anything else?"
"The flowers Madam Lu planted have bloomed," the woman said. "She requested that I deliver you a bunch along the way. The Main City's work is very busy, and the Madam urges you to make sure to rest and take good care of yourself."
After a short silence, Lu Feng asked, "Is she still in good health?"
"Everything is normal."
"Thank you." Lu Feng's voice dropped somewhat. "Give her my regards."
Their conversation ended there, and after the door closed again, there was no other activity within the room.
The weather forecast stated that the gales would continue and the temperature would drop.
The sound suddenly stopped, presumably because Lu Feng turned off the TV. Then footsteps gradually approached as Lu Feng returned to the bedroom and then sat down at his desk. After a few sounds of sheets of paper being flipped, a silence descended upon the room, and there was only the sound of Lu Feng's breathing.
An Zhe wanted very much to extend a few hyphae out from underneath the bed and see what the Colonel was doing, but he didn't dare to. At last, he slowly went back the way he came through the vent.
At the four-way intersection, he chose the direction that the wind was blowing from, and with the slender hypha he used to mark his path in his wake, he continued forward.
The wind, ice-cold and smelling like blood, blew at his hyphae. The pipe walls were connected to other pipe mouths, and each pipe mouth was connected to other complex pipe structures. At the same time, there was yet another intersection up ahead—a path merely this short was enough to make An Zhe realize the complexity of the entire system. He didn't have a road map, only knowledge of the Lighthouse's general direction, so he could imagine the difficulty of entering the Lighthouse via the pipes.
But he could keep searching, for he was by no means an impatient mushroom.
After several turns, An Zhe was completely unable to discern directions, nor did he have any way of being conscious of the passage of time. He only knew that when he was traveling in the direction the wind was blowing from, the pipe would get wider and the wind would get stronger as well. He guessed that this was because he had found the ventilation system's backbone. Sometimes, he worried that his hypha would break, but he could not reinforce it or leave another strand. To mushrooms, their hyphae were like blood to humans. Excessive blood loss would lead to death, so he couldn't use it all up.
Sometimes, there would be wire mesh or some sharp turbines that seemed capable of slicing up all flesh and joints up ahead. At these times, he would carefully slide past the cutting edges to avoid his hypha getting severed.
An Zhe didn't know how long he had traveled for. Only the sound of the wind and the minute rustling of his hyphae moving over the rusted pipe walls accompanied him.
In front of him was an infinitely long black pipe, and behind him was the same. This feeling made him return to the span of time when he lost his spore— mindlessly wandering here and there in the Abyss, perhaps he'd find it tomorrow, perhaps he'd never be able to find it.
When the pipe's diameter was as wide as the height of two men, An Zhe felt a blurry red glow light up ahead. He moved forward, carefully passing a large turbine—then unexpectedly fell out of the pipe mouth.
He landed on the hard and rough metal ground and was illuminated by the dim red light. An Zhe looked around—this place was no longer the inside of a pipe, but rather an open and roomy cylindrical space. It was as big as the Garden of Eden's main hall, and both wind and the red light poured in from above. It was too high up, so An Zhe couldn't feel it.
His snow-white mass elongated on the ground, and the hyphae gathered together to become a human body and skin. It was very cold, so the hyphae spread over his body, creating a closely-woven loose white robe that blocked the biting chill outside.
An Zhe stepped barefoot upon the metal floor and lifted his head to look upwards.
A massive turbine was placed at a slant at the very top of the entire space, and it occupied his entire field of vision. A dim red curtain of laser light shone around the turbine, similar to the city walls of the Outer City. He knew that this was one kind of the humans' defense weapons. As soon as a creature attempts to pass it by force, it would immediately trigger an alarm.
Looking past the turbine's iron teeth, 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, and after the turbine started up, the air from the world outside would continuously be taken in and then supplied to the pipes in all directions.
He retracted his gaze and looked forward. In the center of this cylindrical space, there was a rectangular metal workbench—it may have been the console for the entire system. He walked over, but he discovered that it was not the case.
Upon this metal platform, three small rectangular boxes were welded. Using the light, An Zhe could see that next to the boxes were mottled writings that seemed to have been plated on.
An Zhe leaned down slightly and wiped away the dust and rust to clearly see those cramped writings.
It was a letter.
' To those who come after:
I am Kang Jinlan, the person in charge of constructing the Northern Base's underground ventilation project. The ventilation system took one year to design and nine years to build, with a construction cost of 110 million yuan per kilometer.
Opponents have suggested delaying the construction period due to the difficulty of the base construction and the enormous amount of manpower and resources consumed. But through discussion, we believe that once the weakened geomagnetic field continues deteriorating, within ten years, the human economy will inevitably collapse, and within fifty years, the surviving humans will inevitably lose the entirety of heavy industry's research and development along with production capacity. The means of production and focus of scientific research are all biased towards the medical field. We no longer have time.
Fortunately, the construction of both the underground ventilation system and the aboveground base have been completed without any issues this year, and my fellow humans can live under the strict protection of the base from now on. This is the only thing I feel relieved about. Thanks to cosmic radiation, despite being under strict protection, I'm still suffering from various cancers and autoimmune diseases. I have requested that the base inter my ashes in the ventilation system's core. That way, when each generation of engineers enters it for maintenance, I can know that the base is still safe and that the great species of humankind still exists.
May you have a bright future.
Best regards
June 2030.'
These were ashes.
This box contained what was once a human body. It was a tomb, and these writings left behind were a message this human left for later generations.
Perhaps it was more appropriate to call it an epitaph.
An Zhe looked to the right. On its right side was a box that was almost identical in shape and welded to the table surface at the bottom. There were plated words next to it as well, a letter with an identical tone.
' To Mr. Kang Jinlan, and those who come after:
I am Liao Ping'an, the person in charge of the Northern Base's underground ventilation system project maintenance. The ventilation system is serviced every half a year and undergoes overall maintenance every two years. At present, it is operating in perfect condition.
As Mr. Kang expected, not only did the situation with the weakening geomagnetic field not improve, it completely disappeared in December of the year 2030 instead. Fortunately, the artificial magnetic pole projectsucceeded not long afterwards, and the world once again came under the protection of a magnetic field. Humans no longer suffer from illnesses because of radiation exposure. Unfortunately, cosmic radiation gave rise to the infection and mutation of bacteria, fungi, and viruses, and humankind has met an unprecedented catastrophe. As one who experienced this catastrophe, I've witnessed the shrinkage of the territory in which humans live, the collapse of the economic system, and the gradual loss of industrial capacity. The base has invested all of humankind's remaining production capacity into military production, the construction of military bases, and the expansion of the base, producing a steady stream of guns, ammunition, nuclear weapons, aircraft, armor, and tanks. I do not know where the purpose of this base lies, nor do I know if these actions have accelerated the depletion of humankind's resources. I can only hope that the base has a deeper purpose.
In the midst of this catastrophe, I have unfortunately been infected with deadly bacteria. As my life is coming to a close, I am still feeling endless panic regarding the base's future, so I chose to be interred here with Mr. Kang and wait for the next generation of engineers to report that it is safe.
May you have a bright future.
Best regards November 2052.'
Next was a third box of ashes and epitaph.
' To Mr. Kang Jinglan, Ms. Liao Ping'an, and those who come after:
I am Yang Ye, the person in charge of the Northern Base's underground ventilation system project maintenance. The ventilation system is serviced every half a year and undergoes overall maintenance every two years. At present, it is operating in perfect condition.
I must inform the two predecessors that in this era, the ventilation system is no longer one of the base's countless infrastructures, but rather has played a peerlessly brilliant role in protecting humankind's safety. In the year 2053, the start of global biological mutations, the human bases have committed themselves to the vast defensive war with the military as their primary forces and the civilian mercenaries as auxiliary forces. With the deficiencies in resources and industrial construction capacity, the strong military bases and powerful military weapons left to us by the previous generation have played an unimaginable role, ensuring the safety of the remaining humans. And after being transformed, the ventilation system has become one of the defenses of the base's Main City, protecting people from the invasion of insect monsters.
At present, the Northern Base is still safe. The military and mercenary teams are continuously bringing back monster samples fromthe outer world and recovering scientific research equipment, cultural documents, and other needed materials from abandoned cities. The base's scientific research strength is centered on the research of infection theory and human reproduction. At present, no direction has been found for the former, whereas initial steps have been taken for the latter. A large number of new lives have come, and the human population has begun to rise. Although the environment is still hostile, I believe that everything will take a turn for the better.
Under the protection of the base, I die happily of geriatric illness.
May you have a bright future.
Best regards
January 2104.'
An Zhe carefully finished reading, then looked to the side. It was empty, with no more boxes. 2104 was already a very distant age. Perhaps the next generation of engineers would soon lie here too, with epitaphs telling stories of what occurred recently, such as the fall of the Outer City or something else.
Just then, great mournful sounds came from all around. The mighty night wind blew in from the air inlet, and An Zhe shivered. The strong wind was like an unstoppable flood current, rendering him almost unable to open his eyes—he put his elbow up to his eyes to resist the blowing of the gale and bowed his head slightly.
At that very moment, he suddenly felt pain.
In the wind, a length of snow-white hypha fluttered up in his peripheral vision. The white shape flickered, then disappeared in an instant.
An Zhe whipped around. Only a short length of the white hypha he had previously left to mark his path dragged along on the ground, trembling in the wind. The fierce wind had broken his hypha, and he didn't know where the wind had carried the broken portion off to.
His pupils contracted sharply, and when he looked in the direction he had come from, six pitch-black holes were lined up, all identical to each other.
