Time Travel? It's Still the End of the World!

The founder of a listed company worth hundreds of millions, slept in the office and was reborn back to his high school days. The world is different from the original one, it is actually the end of the world! Is this a zombie? This thing can actually run! It's not like most time travels come with their own system, some cheats or something like that, but I don't have any hair. Hey! No, I seem to be able to predict what will happen in the next ten seconds! ! ! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
