If you were to ask who was most affected by Shen Shili's sudden mastery of the Iron-clothed Shirt, it definitely wasn't Yu Zhilang.
After all, Yu Zhilang actually didn't really need the martial arts technique of the Iron-clothed Shirt.
The technique is based on Inner Strength and is, according to Ji Tianqi's knowledge, originated from the Vajra Unbreakable Divine Skill he acquired from an otherworldly realm.
However, once mastered, it only increases defensive power and doesn't enhance physical qualities overall like the Vajra Unbreakable Divine Skill, such as increasing speed and strength.
Based on the test results after Luo Xiancheng mastered it, speaking more positively, it's similar to wearing a suit entirely made of 'iron.'
To put it bluntly, it's just like wrapping oneself in a layer of iron.
