The properties of Sunflower Inner Power and Bird Killing Sword Technique are quite special, and since only Jiang Congshu has mastered them, they do not hold any reference value for now.
The characteristics of the Iron-clothed shirt are very straightforward; on one hand, it can cultivate Inner Strength with an efficiency of one level per year, which on the monitor data is equivalent to one point of energy, that is, one kilogram of TNT explosive.
On the other hand, it enhances defensive power, and the specific effects are equivalent to wearing a suit of iron armor.
This has great reference value because according to Ji Tianqi's statement and the test data from those who have mastered the Iron-clothed shirt, 'a layer of iron' can be considered the limit of this Martial Art, as well as an inevitable Superpower that one can obtain after mastering this Martial Art.
No matter who it is, they can obtain such an enhancement.
