The original Legendary Warrior 43 to 44 takes a certain amount of time because the experience required to upgrade gradually increases with the level, and the original Legendary warrior's upgrade speed is also related to factors such as class, equipment, and skills.
In addition, the amount of experience required to level up may vary between versions of the game.
Therefore, it is impossible to give a specific time.
Players need to improve their level through continuous grading, fighting monsters, doing tasks, etc., but also need to pay attention to reasonable allocation of time, improve efficiency, so that they can upgrade faster, and have a better experience in the game.
