Although having promoted to LV 10, Zhang Tie was not satisfied with his current achievement; instead, he continued to improve his fighting strength.
According to Heller's suggestion, after promoting to LV 10, he'd better eat all the iron-body fruits so as to raise his strike-resistant ability to a new height.
Previously, it took him at least 7 days of strike in Crystal Battle Fortress for an iron-body fruit. However, after falling in the hand of Senel Clan, it only took him a few days to form 5 iron-body fruits. Given this fast speed, it could be imagined how cruel torture had he experienced.
Take Zhang Tie's leg as an instance. The leg was fully broken one part after another using instrument of torture. This sharp pain was as unbearable as in the hell. Besides the stripe on his scalded skin all over his body, there were other kinds of cruel tortures, each of which could collapse commoners.
