The reason is simple: first, the Vajra Indestructible Divine Skill is merely a supreme martial art, and buying it only costs a few thousand points, but the Undying Golden Body is an undeniable supreme martial art and buying it would cost a hundred thousand points.
Secondly, the description of the skill clearly states the strength of this martial art.
Even the Ten Thousand Swords Return to the Sect cannot break through it unless the weak point is hit, and there is nothing one can do.
Can the Vajra Indestructible Divine Skill withstand the Ten Thousand Swords Return to the Sect?
I'm afraid not.
So, undoubtedly, the defensive ability of the Undying Golden Body is far superior to the Vajra Indestructible Divine Skill.
But one drawback is that, like the Golden Bell Shield, this supreme martial art has a weak point.
If an opponent of the same level finds this weak point, it would be very awkward.
"Even so, this martial art must be learned,"
Chen Fan thought silently.
