"Ask any of them to come and ask for forgiveness to my Friend Sun Mo, if they can then I will Change my decision" Chiyou told Spirit King
The Spirit King became worried
Asking for forgiveness sounds easy but it is not so easy as people think that it will make them look small or they will hold no value to others.
And so, they don't think about the consequences of what will happen if they don't understand their mistake.
Tao Yong is right now desperate to protect his family's bloodline and after seeing someone as the owner of the spear, he feels that heaven is on his side, making him more arrogant
and an arrogant person would admit his mistake.
As for Tao Xiurong, She can be persuaded but will she really agree? As she disliked Chiyou and having a mindset of childlike, she won't budge easily.
All in all, making a single person admit their mistake and ask for forgiveness is hard
