The future world, how humans face dangerous creatures

In the world of the future, the total number of humans is rapidly decreasing due to the growing spread of plague and the dangers of new species, and most of the remaining people are entering the high-walled cities to live in for shelter.

Old Mo, a medical researcher, has recently discovered a species of hydra, a worm that evolves extremely fast and can quickly adapt to its surroundings so that under harsh conditions it begins to feed on toxins and purify the surrounding ecology, and so in nature, life begins to return. But the biggest problem encountered so far is the spore dust, which is a spore plant emitting toxic substances, human infection simply can not be cured.

Xiao Shuai came to Lao Mo, wanting to go with him outside the high wall to find a cure for spore dust infection, Lao Mo advised him not to take the risk easily, you know nothing about outside the wall. But Xiao Shuai said that the high wall will be permanently closed from tomorrow, tonight is the last chance to leave the city, if the spore dust continues to spread, we can only wait for death inside the high wall.

So, when dusk came, Old Mo and Xiao Shuai secretly took the last train out of the city.

It was a fungus plant that was parasitic on the human body. When Lao Mo found it, the host had been dead for a long time, and he thought that this fungus might be the source of the spore dust. Xiao Shuai advised him to stay away from that thing, but Lao Mo wanted to dig up some samples of the fungus to go back and study it properly. When the tip of his knife just touched the fungus, the fungus began to expand, spore dust directly to the old Mo's face, the old Mo fainted with a headache, no matter how Shuai called but also no response, in a trance, he seemed to see the daughter who died of spore dust infection.

When Old Mo woke up, but Xiao Shuai disappeared, he went to the water to wash his face, and then came to the side of an abandoned mine, Old Mo used fluorescent lights to go forward, but found that the walls were littered with the fungus just now. Suddenly he found his daughter again, at which point Old Mo's memory also returned to the day his daughter died, and he and his wife watched helplessly as she departed. When the old Mo again slowed down to see the truth in front of him, a monster is gnawing on the body of Xiao Shuai, who is obviously amid a hallucination.

The monster that was gnawing on Xiaoshuai found Lao Mo and immediately prepared to attack, Lao Mo was inattentive and was pounced on by the monster, after he got rid of it with force, he immediately threw the small explosive pack towards the monster, but these injuries did not work, Lao Mo picked up the knife on the ground and struggled to lean on the stake, the pain of the wound forced him to drink a bottle of fortification, at this point Lao Mo realized that he wanted to live and the monster had to fight to the death, he Picked up the fluorescent lamp, closed his eyes to feel the monster's attack, just as the monster lunged, old Mo directly smashed the fluorescent lamp to it, fluorescent liquid sprinkled all over the monster, old Mo also found the right time, a knife into the monster's chest.

The next day, Lao Mo saved Xiao Shuai and used the monster's gland to cure them both of the infection of spore dust, the original fungus and the monster is a companion predatory relationship, the infection eliminates the weak, and then the world will be transformed into a new environment suitable for them, this companionship is relatively rare but exceptionally powerful.

Finally, the old Mo also lamented that humans trapped themselves within high walls is not the solution to survival, no species can survive on its own, the emergence of the hydra has been changing the environment, and we, humans, are only a part of nature as a living organism.
