Traveling Through Another World, I Use Magic Power to Cultivate Immortality

Lei Ming was originally a commissary in a large factory. One day he died suddenly while working overtime and was reincarnated into a different world, becoming a newborn of the Menes family. His parents in this life named him Rhine Menes, but what they didn't know was that this name would resound throughout the world decades later. Rhine has been different from other children since she was a child—— While his peers are all playing in the mud, Rhine has secretly learned the language of this world; While his peers are still worrying about enlightenment readings, Rhine has begun to study the use of magical power to practice medicine; Peers of the same age are shining brightly in the magic academy, Rhine... Rhine has successfully become a little transparent! Of course it's not that Rhine was a loser, it's just that he no longer bothered to fight for fame and wealth after having lived a lifetime, and squeezed into the Royal Knights to become a glorious "civil servant". And when a few years later, the leader of the Milis Royal Knights, the Queen of the Holy Maro Empire, and the senior mentor of the Continental Magic Association discovered that the little transparent person who was harmless to humans and animals in the past suddenly became an SS-level adventurer of the Adventurer Association, the founder of the Demon Immortal Flow, and a figure comparable to the gods? And Rhine was already crying urgently: "Stop chasing me, stop chasing me. If you chase me again, I will be forced to discover the truth of this world!"
