Si Mo Fan and Yan Xi settled in city close to where Si Bai was located with Chen Ji Yue. They wanted to stay close to their son, but they also know that too close wouldn't be good.
So they pick a city that was only a few incense sticks of journey away. Of course, this journey was if they were walking.
If it was by horse, one to two incense stick of time should be enough.
They bought a house and lived like an ordinary couple there. Their neighbors and people around them would never guess that this seemingly amiable person was actually the leader of Dark Moon Organization in the past.
Of course, Si Mo Fan also had no intention to let them knew in the slightest bit.
In this situation, Si Mo Fan and Yan Xi were living a happy life.
