Be Invincible from Practical Teaching

[Invincible + Multiple heroines + Never feel aggrieved + Time Travel] [The characters and content of this novel are purely fictitious, any similarities are purely accidental] (Write it yourself, read it yourself, vent your emotions) It is purely fictitious, without any bad guidance. And does not have any of the following behaviors: The first is violation of laws and regulations; the second is plagiarism and infringement; the third is vulgar and pornographic; the fourth is political sensitivity; the fifth is historical emptiness; the sixth is excessive bloody violence; the seventh is discrimination against vulnerable groups; the eighth is promoting cults; the ninth is infringing on personal privacy; and the tenth is undermining social order and good customs. In that world full of injustice, I gradually understood that the so-called "fairness" may be an ideal, not a reality. The principles of fairness that teachers once taught us seem to be just empty slogans in reality. For those who have power, they are nothing more than tools used to maintain the status quo. For ordinary people like us, they seem to have become shackles that bind us.
