Doraemon Begins with an Immortal Body

I am Tang Song, and I came to the world of Doraemon inexplicably. The system at the beginning rewarded me with an immortal body, and then I started to seek death. I fought with one against ten thousand in the Iron Man Corps, fought against the devil in the adventure of the devil world, cut through thorns with a sword in my dream, and defeated the monsters with supernatural powers in the past.
