The luminescent algae are quietly hanging eternally on the walls of the Underground World, bringing the descendants of those exiled the joy of light.
This kind of plant had once been analyzed and discussed about in another world. The theory in question had probably been the assimilation of the DNA of a firefly into the DNA of an algae, allowing the fluorescence of the firefly and the light of a plant collaborate together to create an energy cycle flow with a minimum loss of energy, effectively creating a self-sufficient system that could provide continuous light for the underground.
It could be planted in mines to prevent them from collapsing and one of its derivatives, Algae Bulbs, could be used for illumination in public. Using the luminescent algae source to improve society's energy structure… It may sound wonderful, but the technology hurdle for it had been simply too great. Even if we could have resolved the gaps in technology, if we forcefully had combined the DNA of a plant and animal, who knew what kind of abomination would have been created? In the end, it got terminated at its theoretical stage.
I never expected that the purely theoretical discussion that I read abou
