Of these five Inner Strength techniques, Xiao Jie didn't even consider Wild Bull Skill, Body Building Decision, or Hard Qi Gong.
On one hand, his attributes didn't meet the standard; on the other hand, they weren't the kind of Kung Fu body he needed.
The only thing he needed to consider was between Qi Nourishing Technique and Flying Goose Skill.
Qi Nourishing Technique offered a higher limit of Inner Power and also had a regenerative effect.
Meanwhile, Flying Goose Skill could enhance the effects of movement techniques, which were also quite beneficial enhancements.
However, after a moment of hesitation, Xiao Jie decisively chose Flying Goose Skill, and his reason was simple. While the increase in Inner Power limit and regenerative effect seemed good, they wouldn't directly affect combat power, only endurance. Unless a battle lasted a long time, long enough to exhaust one's Inner Strength, otherwise, it wouldn't have any effect.
