He said this just to sound nice on the surface, but in reality, he was calculating the whole time in his heart.
Blood-line enslavement had the effect of a blood connection, allowing him to track Jiuji's location at any moment. Plus, since they were now inside Tiandi Sect, her movements in and out would be restricted. If Jiuji wanted to go home and find people to take revenge, it would take her a certain amount of time to accomplish. During this period, he would have plenty of time to pack up his family and flee to take refuge, so he wasn't afraid of revenge from Jiuji at all.
However, Jiuji had no idea what he was calculating in her heart at this moment. Seeing that her husband trusted her so much, Jiuji couldn't help feeling somewhat moved inside. The brutal acts her husband had committed against her initially were now completely drowned out by his current kindness.
