Reincarnated in a Wyrmhole

When a programmer dies saving his friend's life, he is reborn inside an egg with full memory of his past life and a mysterious voice inside his head. He is hit with fire and fangs right from birth, and the new world is a constant fight for survival. Will he survive? Will he reach the top of the food chain? And will he get back home?
This will be heavily based on various isekai anime, but no characters the same from any of them. Violence and death but no gore.
