let's get physical lifetime real story

Lucan Ironfist came from a noble family, but he wasn't the eldest son. When his brother became the head of the family and he turned 18, Lucan would become a commoner. A strange rule, but that's how it was. So Lucan began to think of a way to live a peaceful life. As he was considering this, his mother arranged for him to become a priest in another city. A priest didn't have to worry about food or housing, and all he had to do was watch over the temple and the statue. It was easy work, so he agreed and arrived at the city. One day, as he was watching over the temple and the statue, a poor-looking girl came to pray. When she prayed to God, light gathered around her body. Lucan was surprised and suddenly remembered the plot of a certain game. Originally, Lucan was from Earth and had traveled to this fantasy world. When he was on Earth, he played a game with a plot where a merchant family's illegitimate daughter, bullied by her family, awakened the power of a saint. Lucan decided to keep this secret and train the saint so that in the future, he could have an easy life and save himself from any crises. --- **Please do not rate the novel until you have read at least 20 chapters.
