Rebirth Begins with a Baby Megalodon

Reincarnated in a different world, he became the overlord of the deep sea, the Megalodon. Start as a cub, expand your territory, conquer the Neptune, and dominate the ocean. Strange tides swept across, energy surged, and spiritual control led primitive people to rise and worship sharks as kings. The intersection of time and space creates the strongest summoned mythical beast, the battle of technology, the devouring of nuclear energy, and the transformation into the master of monsters. Aliens invade, control the laws of the universe, and the strong are respected: "Natural selection, survival of the fittest." [The age of paleontology (mediocre beast fighting, in progress), the age of summoned beasts, the age of technology, the interstellar age]
