Yang Jian magic rope

Having his Xian Binding Rope still tightly bound upon the prime minister, and considering the current overpower on the side of Zhou, Sun had little choice but to retreat in a state of intense rage at the thought of his rope being taken away from his grasp permanently — thus increasing the probability of loss rather than an essential victory. As the Zhou forces returned to the Phoenix City, each general realized that the rope around the prime minister only grew tighter around his body whenever an individual attempted its removal.

Yang Jian, who was naturally akin to such situations, placed a single magical charm upon the rope, which caused it to fall to the ground immediately following. Informing the prime minister that such a rope was none other than the 'Celestial Binding Rope', and was used by Krakucchanda within the Vehement Flame Trap, Yang Jian obtained consenting to meet Earth Traveler Sun the following day to ask the reason behind Sun's actions — and more importantly, how he even obtained the rope.
