The Monkey King establishes himself as a powerful and influential demon. On hearing that Dragon Kings possess many treasures, and in search of a weapon, he travels to the oceans and finds the palace of a Dragon King. At the entrance Sun Wukong asks for an introduction, but the Dragon King Ao Guang tells his guards to turn him away. Sun Wukong barges in anyway, brushing off protests from the guards, insisting the Dragon King must be confused to turn away a fellow King. Inside he introduces himself and encourages the Dragon King to give him a weapon. Quickly realizing Sun Wukong is quite formidable, the Dragon King feigns willingness and hospitality, ordering his underlings to bring out weapon after weapon. Sun Wukong tests each weapon, but none are robust enough for the Monkey King who is unhappy at the situation. Sun Wukong then acquires the Golden-banded staff Ruyi Jingu Bang/Ding Hai Shen Zhen (如意金箍棒/定海神针), the stabilizer of the Four Seas and a treasure of Ao Guang, the dragon-king of the Eastern Seas. The Monkey King is the only creature strong enough to wield the staff-like weapon and there is an instant affinity between them. The Golden-banded staff can change its size, elongate, fly and attack opponents according to its master's will. It weighs 13,500 " jīn " or 7960 kg. When not wielding the weapon, the Monkey King shrinks it down to the size of a sewing needle and stores it in his ear.
