43 Chapter 40: Another breakthrough, Body Refinement Level 1!

As the most hammered areas, such as the knuckles and instep, began to darken,

Chen Yi truly stepped into the threshold of Iron Skin.

After the formation of Iron Skin, he found that his internal Vitality and Blood were no longer sufficient,

In the month of the perfect completion of Stone Skin, his Vitality and Blood power increased by more than 100 strands, reaching almost 500 strands. The moment Iron Skin formed,

Its rapid rush towards his hands and feet consumed his Vitality and Blood power at a pace several times faster than any other martial arts school disciple he knew of when they broke through to Iron Skin!

Chen Yi felt something was off. His total Vitality and Blood had long surpassed the total amount of Iron Skin Martial Artists in the martial arts school by four or five times,

Even exceeding some ancient full body Iron Skin martial artists from the legends,
