Worldwide Classchange: I Got Five Elder Sisters Supporting Me While I Level Up

In a world where the game became reality, everyone had to choose to change classes. Countless abysses and secret realms appeared in the wilderness, and people could level up by slaying monsters. Victor King transmigrated and became the family's most favored youngest son. His eldest sister Abigail became a Dragon God Knight, flying across the sky on her giant dragon, completely invulnerable to curses and spells. His second eldest sister Bella became a full-time mage, with a mastery of the full-level affinity for the nine elements, known as the strongest weapon on earth. His third eldest sister Catherine became the God of Cursed Arrows. She never missed, while she could reduce the enemy's speed and damage and was good at crowd control. His fourth eldest sister Doris became a Shadow Ranger, walking in the dark. The moment her enemy saw her blade, he would immediately lose his life. His fifth sister Emma became the Holy Light Bishop, purifying everything and healing everything. As for Victor, he had the misfortune to become a classless role, but that didn't matter. I got five sisters backing me up!
