This is a heart-wrenching story. Although Chen Kai displayed no expression, his eyes were already brimming with tears. He knew that his family had been part of a complex clan.
However, he did not know why it abruptly turned into what it is now as all of this happened before he was born. As his father had already mentioned, it all transpired when his young grandfather was still around.
He couldn't participate at all, not to mention, this was not something glorious. On one hand, it was kept from him to protect him, and on the other hand, to prevent him from feeling sad once he came to know about it. Hence, it was kept hidden all along.
If it weren't for a chance encounter with Qiao Zique, and if his grandfather hadn't sought treatment for his internal injuries from Qiao Zique's grandfather, then he would not have made it to Devil's Capital today, nor would he have known that his family had a longstanding enemy.
But the story doesn't end here.
