Although he was not the crown prince, his parents never treated him differently. When Yun Yanli was severely injured as a result of a catastrophe he experienced, he went into a coma for ten days and ten nights. For the whole time, his parents never left his side. He could clearly remember the happy tears they cried the moment his eyes opened.
From then on, he made a promise to guard heaven with all that he could, even though he was not the crown prince that would one day succeed his father's kingdom. He tried his best to cultivate and to become a stronger man day by day. Eventually, he became the admiral in heaven who ran the entire fleet of 10,000 divine troops.
