Ultra's Almighty System

Mengying is an orphan, but he is also a genius. He completed all his studies at the age of fifteen, became a physicist at the age of sixteen and won the Nobel Prize in Physics, and became a mixed martial arts master at the age of seventeen. But it was announced that such a genius could only live to be eighteen years old, but God once again gave him a chance to become the body of an Ultraman shadow who was less than 3,000 years old in the M78 Nebula Kingdom of Light. At the same time, the Almighty System was awakened, and from then on, an Ultraman named Shadow emerged! This is my first time writing a book, so please bear with me!
