The first day that Yun Che had carried the pig iron, every single step he took would consume a large amount of profound energy. At the same time, his shoulders would be in unbearable pain and his spine seemed like it would at break anytime. After walking for four hundred steps, all of his profound energy would be completely expended; his entire body would be pressed onto the ground by the pig iron and he would also be unable to stand back up for a long time. But after a slight recovery, he continued to march onwards, and carried that chunk of pig iron without the slightest intention of stopping.
Just like that, Yun Che walked the entire three hundred and fifty kilometers. For food, he had his unchanging dried rations and the low level profound recovering pellets he made, while his drink was the water he prepared at the waterfall from the Scarlet Dragon Mountain Range.
