Although this was not a rare thing, as there were many alchemists who had stopped at the seventh level. Some of them could not make any progress for their entire life, let alone a hundred years. Most of them couldn't even touch the threshold of the seventh level. It was already rare for them to reach the level of Qing Danzi, but Qing Danzi was still unwilling to accept it.
In the past, he was a super alchemy genius who rose to the sixth level in just a few decades. Then, he successfully reached the seventh level before the age of 100. At that time, he was famous all over the world and shocked the alchemy world!
However, just as everyone, including himself, thought that he would become the next Mystic class refiner, he was suddenly stuck. And he was stuck for more than two hundred years. Until today, very few people in the world of alchemy mentioned his name, and even if they did, they would only say that he was ordinary.
