Several years ago, she witnessed something that she always kept in her heart.
It was just that time when the factory was haunted that really scared her. For some reason, Su Qing felt that nothing good ever happened when she confronted Su Keqing.
So she had always buried that matter in her heart until she saw this post today.
Su Qing believed this was a heaven-sent opportunity to get back at Su Keqing.
With so many posts on the forum, her stealthy addition would certainly go unnoticed.
If Su Keqing were to investigate, she would surely first find the person who started the post. Moreover, Su Qing and Su Keqing had not interacted for three years, so she wouldn't be suspected.
Unfortunately, her plan was indeed good, but she didn't know that Gu Shengyin had a system plug-in.
The other person who posted looked at Su Qing's anonymous post and turned pale.
