Jing Xun, the second prince of Tianjie, was a dashing person. He walked around all day long and did everything except serious matters.
The Emperor of Heaven has tolerated him for a long time.
Finally, on a day when everyone was celebrating, the Emperor of Heaven was furious and demoted the idle Jing Xun to the human world to experience the hardships of a human emperor.
These are irrelevant matters to Marshal Tianpeng who guards the north of the heaven. However, the Emperor of Heaven was still worried about Jing Xun. Before Jing Xun's calamity, he first sent Tianpeng to the human world to protect the second prince.
Tianpeng couldn't figure it out, how could he protect the second prince in the human world after losing his memory?
Tianpeng didn't know that as soon as he went to the human world, Jing Xun rushed to Yue Lao's mansion and said excitedly: "Tie the red thread between Tianpeng and me in the human world!" He thought for a while and added: "It's a knot! The kind that can't be untied!"
