Review Detail of always0000 in Dragon of Time Control

this novel is interesting to read at first but then it gets very boring, the author makes the protagonist a eunuch, using the excuse that he would only be with dragons like him, but these types of dragons do not exist, dragons are not lustful? he himself said he doesn't fight against his draconic nature, anyway the author makes him a shitty eunuch who is only interested in knowledge, he almost doesn't do other things in life, that makes the story shitty.
