Here, strength means everything! The weak eat the strong, and the fittest survive! The human race, which has always been at the bottom, has gradually developed two paths in order to become stronger. You can become a messenger, with ever-powerful abilities and unlimited potential in the future, but this requires God's gift. If you don't have talent, I'm sorry. Similarly, you can also become an explorer, traveling to different worlds to learn and gain abilities. Thus becoming stronger! But there are great dangers in every adventure, and you can easily lose your life! This one has a dangerous and unstable path.
