The real jade tripod is actually a disciple of Yuan Zun, but Yuan Zun is different from his other disciples. A real person like Taiyi can get many treasures from the original Buddha. Although he may not be as strong as Ding Yu, Yuanshi Tianzun just doesn't like Ding Yu. This is because the original Buddha attached great importance to the orthodoxy of sects, and the real jade tripod came to the teacher with thousands of years of practice and skills.
Therefore, Yuan Shi Tianzun felt that although he was his disciple, the skills he learned were not all his own orthodox spells, so he didn't like him and taught and guided him a lot less. At that time, Ding was a real person who helped Dayu control water, so he sealed the cauldron of Kyushu and carved a picture of seventy-two changes on it.
Although the real jade tripod knows that it is precious, he still can't understand the mystery. If this mystery is understood by him, he must be the most powerful of the twelve golden immortals, but he has never been able to understand it, and there is no guidance from the Buddha at the beginning, so such a precious thing is so idle.
Yu Ding, when accepting two apprentices, Yang Jian and the Monkey King, thought that they had no way to understand and could not do it with their cultivation, so he specially arranged this impossible task for them and wanted to cultivate them. As a result, I didn't expect that both of them were gifted, and both of them learned seventy-two changes, which Yu Ding had never expected.
But at this time, the apprentice understood the secret of seventy-two changes before the master, but the master was embarrassed to ask the apprentice and said that he would not change seventy-two changes. So the real jade tripod will not change in the end, but his two disciples will.
