One day every person on the planet suddenly received a message warning the end of human supremacy over the planet, and at the same time alerting the humans in order to prepare. The message was seen as a joke by everyone or almost.   In the period in which the MC starts some training there will be a time skip, and show only the necessary parts, interesting or that affect the story. I don't have the patience to read or write entire chapters just MC doing nothing but train.  And likely the MC stay well OP.
