The first step is to find his ghost. Usually there is a tombstone at the place where he died, and he will come back to "haunt" him at night.

The second step is to learn how to cook fairy dishes. You need level 10 cooking, level 10 fishing, and level 10 planting. You need life fruit, death fish, and learn the recipes of fairy vegetables to make them.

The third step is to place the fairy vegetables in places where ghosts often come. He will eat it. After eating it, he will come back to life and become the normal person he was before he died. If you want to make him younger, there is a potion invention in Mood for Love. Buy one and invent an anti-aging drug and drink it. Become a young man again. In addition, there is mysterious spring water in the secret spring, and drinking it will make you look younger again. Haha

There is also a mission to bring ghosts back to life. You take the tombstone to the Biochemical Institute (is that the name?), and they will be resurrected there, but the resurrected ones will also be in ghost state, but you can control them. But after a while, he will "die" again and never come back.
