This conjecture wasn't impossible. Baiers was not only Emperor Zhantui's son, but he was also a Heaven Rank powerhouse. In that era, only a few people could compare to him in terms of bloodline.
It wouldn't be strange for the Bloodline Curse left after Baiers' death to make Solan advance from the 2nd Rank to the 5th Rank.
