@Forgotten It would destroy all life on the planet if it de-orbits. Small stuff, depending on what it's made of might not be that big of an issue but there would be thousands of chunks which could each end all life on Earth, not even including the remaining half of the main body of the moon itself.
Putting it back together isn't even the issue, getting it back into an orbit that doesn't decay is the big problem. That requires a level of insane precision that can't just be eyeballed or guessed at. The Earth's orbit around the sun would also be affected by blowing the moon half to bits along with it's speed, spin, wobble, magnetic field and core rotation and for all we know all of these are already irrecoverable. The precision required to support life is insanely fragile and even if the MC magically restores the moon and somehow restores the moon's orbit properly, it's hard to say if the life on Earth itself would still survive.
But, in a world of manhua cultivator magic, I'm sure it's just going to take the MC a few minutes to solve this problem.
