Han Fei was not stingy. With his current strength, as for a great technique like the bloodline devouring, it would take tens of thousands of years for him to upgrade once.
Fortunately, he could accelerate time. Otherwise, if he spent tens of thousands of years improving his bloodline, how slow would his growth be?
Furthermore, Han Fei didn't spread the original bloodline devouring technique, but slightly modified it. Hong Yue had advanced to the Sky Opening Realm, but his bloodline had actually been strengthened during his breakthroughs.
The Green Water Kylin Blood was the bloodline of a fake divine beast, which was suitable for the current Hong Yue to swallow. As for Yingyue and the others, they were not strong enough to swallow even the Green Water Kylin Blood. They could only swallow the bloodline of some legendary or legend creatures to strengthen their bloodline.
However, Han Fei was not in the mood to teach them one by one.
