My Life Can Be Simulated Infinitely

Gu Yang traveled to a world of high martial arts and lived in a small village for two years. He finally saved up his first pot of gold and activated the system, the life simulator.
You can conduct a simulation by spending a certain amount of money.
After the simulation is over, you can choose one of three options: realm, martial arts, and life wisdom.
[You have been a bookkeeper for five years, saved up money to buy a book of exercises, practiced hard for ten years, and successfully became a ninth-level warrior. When you encounter an enemy, die! 】
【As soon as you came out of the mountain, you were in the ninth rank. You became the guardian of a certain family. You practiced hard for twenty years and broke through to the eighth rank. In the end, you died of old age in a small town. 】
【When you came out of the mountain, you were at the eighth level. You were appreciated by a noble family and taught profound martial arts. Due to slow progress, you were marginalized. More than ten years later, you finally broke through to the seventh level. You encountered a powerful enemy in a certain mission and were killed. ]
...
After countless simulations, [no one you meet is your opponent. You realize that you are already invincible. 】
