Su Yi was focused on his cultivation, each step he took seemingly carrying the weight of a thousand pounds, causing the ground to tremble slightly. Dozens of weight-bearing cloud irons were strapped to his limbs; these were extremely heavy, and even lifting just one piece would be incredibly difficult for anyone else. At this moment, Old Wang had struggled greatly to lift a thousand-pound piece of cloud iron, but after only a few steps, he was already panting heavily, on the verge of exhaustion. Seeing this, Su Yi immediately stepped forward and steadily took the cloud iron from Old Wang's hands. In reality, Su Yi was practicing a unique qigong. On the first and fifteenth of each lunar month, he would increase his weight by a thousand pounds, which he would apply whenever he engaged in combat.
