Jiang Fei experienced mixed feelings after obtaining the Commanding Cauldron. He was happy that the Commanding Cauldron allowed him to increase his Commanding points by 100,000 points, which meant Jiang Fei could now command an army of 1,000,000 soldiers.
However, it was not something Jiang Fei could achieve overnight. That meant that although he obtained one of the Nine Cauldrons of the Ancient Kingdom, his own capabilities did not increase significantly.
Moreover, Jiang Fei was not the only one who could access the Quest Against the Heavens. Anyone who obtained one of the cauldrons could receive the quest. Moreover, the other cauldrons gave a more obvious boost to the owner's capabilities.
