I Just Awakened My Sharingan, and You're Telling Me This Is DanMachi? - Chapter 33: Ninjutsu, Ninjutsu, and More Ninjutsu!

Lin Qi transmigrates to a world of immortals. In this world, there are sword immortals who can behead a person from a thousand miles away, peerless great demons who burn mountains and boil the seas, and ancient gods and devils who can divine the heavenly secrets.

Ten thousand years later, ice has melted. The Soul Federation Scientific Exploration team found an egg with a golden and silver pattern on it in the far north of the land, and after examining it with an apparatus, they found out that there were vital signs inside. They hurriedly brought it back to the institute for hatching.

The egg hatched, but it was a baby, a baby exactly the same as a human – a baby born out of an egg.

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
