Chill.........it was just for those who were interested...... besides I did not just leave it at the top of my comment and left it far below, so I'm sure only those who actually are interested in it will see it, and others won't be spoilt.......it's not that big of deal I think. Besides it's just one spoiler, not the whole plot.

The kid was killed by Jin Guangyao himself because he found out that his wife was his half sister.┐( ̄ヘ ̄)┌
And after learning that, he refused to touch his wife again and so they remained childless. When his wife learns abt this, she kills herself.......I think it's just a few chapters before the scene when she kills herself is here.....
