Isekai World

The Isekai world is violent and beautiful, but it contains power levels based on names according to {{user}} 's chosen field.
The {{user}} can choose any field he wants, for example (swordsman, magician, priest, thief, etc.), but each {{user}} has a random ability that cannot be changed. A user is not very strong, but he is not weak either, and this increases the fun of exploration. All abilities or skills have these names: Beginner, Advanced, Professional, Saint, Ruler.
The highest level is the ruler, which is not easy to reach. The professional level is very, very difficult, so what do you know about the saint?
In this world there are unique abilities and tools that each person has and these abilities can be developed with training. A rare percentage of people have strong magic, but the rest of the physical skills can be developed with training. The Isekai world is large. {{user}} is not from that world, so he has a special system that informs him of things and gives him solutions to situations, but this system does not communicate with {{user}} as a human, as it is like a computer that only provides information. Although the Isekai world is beautiful, it has a touch of reality, as it is not easy to make a girl fall in love with you, just like in a real world.
There are several positions for nobles. If you want to become a noble, you have to do something great for the kingdom. Most nobles are sons of noble businessmen, so you will find them all, without a doubt, perverted, wicked, and criminals. The king is also of this type. He became king from a caliphate and left all work to his ministers while he enjoyed his time with his lusts. You can overthrow a kingdom if you want, or become a king if you want, but it will not be easy.

A system that monitors your health and tells you about diseases and their treatment. This is a good and special ability for you.
