The Great Teachers Hero Rankings accepted new great teachers below 30 years old with powerful strength, outstanding talent, boundless potential, and immense fame.
Great teachers who could ascend to the rankings would surely have some achievements in the future.
The growth of young great teachers was something terrifying. This was especially so for those geniuses. Before 30 years old, regardless of their cultivation base or teaching abilities, everything would improve with drastic speed.
Hence, great teachers who could enter the Great Teachers Hero Rankings would usually be above 25 years old. There was no solution for this. For an occupation like teaching, one would naturally grow more experienced as the number of years they taught increased. The stronger they were, the more money they would be worth.
