Back to 1993: Becoming the Greatest Stock God!

A beam of light strikes, and Tang Sheng transmigrates through time and space to a parallel universe, where it is thirty years earlier.

Tang Sheng doesn't know whether he can return to his own world, or whether anything he does in this one will affect the normal course of events in his world. But since he's here, he might as well find a way to make life a little better for his counterpart in this world. Changing the living conditions in his own world would be secondary; the main thing is that life there was simply too hard. Having transmigrated to a parallel universe, he wants to be a little kinder to himself.
