Tang Yin smiled as he saw it, 'So easy to get to Rank A.' He thought to himself as he saw that his rank was upgraded to Rank A.
Although he was at the lower end of Rank A, in rank he was already within the top 300 of the Sect.
His way of advancing was by percentage of wins over defeats, and it wasn't because he had defeated an A Rank, which usually meant that he would soon leave the A Rank and be replaced by someone else.
If such a thing happened, Tang Yin would automatically become the Top 1 B Rank. In fact, it is the same for everyone who leaves a rank that way.
Right now, Tang Yin's ranking position is 178 out of 200. Once there are B-Ranks that advance to A-Rank in the fairest way, which is by beating an A-Rank, those at the bottom of the ranking will start to go down, and those that have not beaten any A-Rank will be the first to go down.
This mechanism is the same for all the Ranks except for the S Rank.
