There's no need to consider that problem for now.
Your other meaning is, if I can alter the route of energy flow in Iron Cloth Shirt, the Thirteen Grand Protectors Horizontal Training Skill, and Golden Body Skill and use Qi more extensively, I can also achieve a state comparable to the "Vajra Invulnerability Divine Skill"?
"Indeed. However, there's fundamentally no need for that."
Wang Yuyan shook her head and said, "The Iron Cloth Shirt and other horizontal training techniques are designed for beginners in hard skill, belonging to simplified foundational Martial Arts.
If you insist on improving these Martial Arts further, that would be complicating the simple. In truth, that is not the ideal state for these techniques and is unnecessary.
The Vajra Invulnerability Divine Skill, on the other hand, is different.
