The Marrow Cleansing Cultivation Technique is the top-secret Genetic Evolution technique of the Great Dragon Empire. Only those who pass a strict selection to enter the Gold Guard of the Great Dragon Empire are eligible to learn it.
When Yang Xiao was on Witch Star, people he knew, like the base manager David and Karachi City Lord Jino, were not qualified to enter the Royal Gold Guard and thus could not obtain the Marrow Cleansing Cultivation Technique.
Although Yang Xiao didn't know this young master of the Qin family, he was certain that no matter how wealthy and powerful the Qin family might be, they couldn't buy the Marrow Cleansing Cultivation Technique of the Great Dragon Empire.
The young master Qin might fool Yelu Caiyun, but it would be difficult to deceive Yang Xiao.
