The Tower of Ruins

Grimm had three crystal balls now—the usual one, the one that contained split souls and one used in the Underground World.

Going back to his dorm, Grimm found that the mushroom seeds had grown up. He noticed some farinaceous spores on the fungi's fruiting body and collected them with meticulous care.

"These stuff hallucinated me and almost got me killed in the forest!" Grimm murmured unintelligibly as he put the spores into a flask.

There was another flask with a ginger, turbid liquid in it. The liquid was an extraction from the stomach of a crane on which Grimm had tested his Gadflies three months ago. According to Grimm's long term observation and examination, this liquid was the key to the crane's resistance against the Gadflies' bad mutational effect—the one that deformed its host.

Another test result related to Gadflies was its role as a Symbiotic Insect in accelerating the host's evolutionary process, especially the process of passive evolution.
