Ji Ning was completely absorbed by the Allworld Tribulation's illusions.
...
Ning became a fisherman's child. When he was young, he would accompany his father in fishing on the sea. He eventually fell in love with a rich man's daughter, but her family looked down upon him. On one seafaring voyage, his father ended up perishing, resulting in Ning braving the oceans by himself. Slowly, the clever Ning learned more and more tricks for catching fish. He gradually accumulated a fortune, then purchased a large ship for himself. As his fishing skills continued to improve, he became a legend amongst fisherman. He eventually had over a hundred sails within his fleet, and the rich girl's family actually came to him to make amends.
