After Wu Zheng left. He heard that Wu JunJing locked himself for weeks and was found dead in his room. He was murdered brutally, his face was scarred and he looks like he didn't even fought with the murderer, he could have but he didn't. JunJing was too guilty and he couldn't sleep knowing that he killed his family.
He even left a letter. A lots of letter saying, how he regret all of the things he did. How miserable he felt. How he wanted to kill himself but couldn't. He even wrote his mother's words that taught him what is love. He wrote his past with his wife and how he killed her. He was depressed and he felt the need to die.
Wu Zheng stared at the sky and whispered, "You are all free"
Wu Zheng wanted to forget his past so he made another name and made himself a doctor. Though his title wasn't forgotten as his second brother reigned the Wu Kingdom.
