The first three levels were the foundation of Metal Wall Technique. Every level after that would give the cultivator a massive increase in power. Once this body martial art was trained to the fourth level, the cultivator‘s body was as tough as a metal wall and impenetrable.
This meant that Zhao Feng could counter Xin Fei with his body alone, and most cultivators of the fourth and fifth rank couldn’t harm him. The fourth level of the Metal Wall Technique not only strengthened the skin, it also strengthened the bones by molding them inside, which meant that the cultivator’s strength far surpassed others of the same rank.
Zhao Feng felt that the changes within his body were very obvious. Without using Inner Strength, his every move and action would still contain unstoppable power.
“I can easily beat cultivators of the fourth rank with just my body. I can even counter against some fifth rankers.”
