From the Iron Shirt Technique to physical sanctification

In the ancient martial arts world, martial prowess reigns supreme. The Punish Evil System grants cultivation time for killing. The Wild Wolf Gang drove the original owner's family to their deaths. Since forbearance means certain death, I'll stop! The system grants me 300 years to cultivate the Crushing Stone Fist. The second-rate Crushing Stone Fist breaks its limits, revealing the true meaning of martial arts: the true meaning of shattering! The third-rate Iron Shirt technique is cultivated, resulting in: an Iron Soul Body! I will slaughter my way through this cannibalistic world. Kill! Kill! Kill! Hehehe! So much cultivation time. I'll become the king of this world in three months! Hehehe! System, don't run away! Come back here!
