To create the new Rewind Metac, he will need some law fragments and some lifespan. These are things he would be able to do with a divine body and a Life Fire.
For now, he can't remake the Rewind Metac. He can't make any Divine Metac since he is dead. But once he bounces back to his feet as a living being, this is a problem that can be fixed.
The problem with this situation is that the Rewind Metac had been destroyed altogether. It should have been nearly impossible for his reincarnation to die since they can rewind time.
The only way his reincarnation can die is if they run out of lifespan from reversing time too much, or a Dao Lord takes action against them. If it is the former, the Rewind Metac should still be safe.
The loss of all of their lifespan shouldn't lead to the destruction of the Rewind Metac, though. Even if someone else had taken it, he should still be able to sense it. The situation shouldn't be like this where he can't sense the Rewind Metac at all.
