Su Mu's eyes lit up slightly, feeling a sense of enlightenment. He closed his eyes to carefully digest it, and not long after, he reopened them with a trace of surprise.
He discovered that in this short time, the proficiency of the martial arts at the level of four doors of Great Success had increased by three percent.
"Not bad, not bad."
At this moment, the aura around Su Mu changed suddenly, and the thin clothes on his body began to flutter, sounding like the indestructible Iron Cloth Shirt that could resist swords and spears.
His arms were even more astounding. As the flesh and blood moved inch by inch, the muscles on his arms swelled, looking much bulkier. As Su Mu stretched his body, a crackling sound erupted all over him.
This was the result of Su Mu obtaining the last two Eighth-Grade Cross-Training Martial Arts from Qingfeng Gang Leader Gu Feng, "Iron Cloth Shirt" and "Iron Arm Skill".
