There are deadly spores on the outside and competition for resources on the inside. The setting of the protagonist Su Ye as a "scavenger" is very important - he has been exposed to contaminated areas all year round and will be the first person to discover that "the spores are periodically weakened". This loophole will become the foreshadowing of subsequent human counterattacks.
Regarding the explosive scene... How about letting him accidentally hear a confidential call while cleaning the ventilation duct? When the metal legs of the mechanical spider pierce the fungus carpet, revealing the giant biological embryo soaked in the reservoir below - the visual impact is strong enough. It is necessary to focus on the uncanny valley effect of the humanoid eyes on the tentacles and the chill caused by the line "human genetic modification project".
In terms of the million-word structure, three main lines are planned: 1) The purpose of alien civilization behind the spore ecology 2) The "human evolution" conspiracy of the SAR ruling class 3) The growth process of the underlying resistance organization. It is important to leave suspense at the end of each chapter. For example, this chapter stops at the moment when Su Ye is targeted by the patrol's laser. The next chapter can cut to his childhood memories of surviving a spore storm to explain why he is immune to infection.
