[Crossover (Mainly Harry Potter)] A Journey Through Time

The sunshine after the rain is always captivating, but the storm that comes before it always leaves people helpless.

The price of success is a road paved with blood. Given another chance, can everything go well?

The regrets of the past life, the changes in this one;

The original wish will never change.

Taoist arts, magic, wisdom;

The gears of time have been set in motion,

And everything will change from the very beginning.
