Chu Mo knew that Jiang Caiyue's information had always been accurate. When she said "seems," it was essentially confirmed. He recalled the battle in the Yanhuang Great Domain against the Imperial Clan's branch line where many Primordial Chaos family descendants had been involved. He even killed one of their direct lineage members, which led to the appearance of a divine sense projection from an ancient ancestor of Primordial Chaos. Though the projection was faint—merely a trace of divine sense—it almost caused Chu Mo immense trouble.
If Chu Mo hadn't already possessed the divine-text battle armor and his cultivation wasn't profoundly advanced at the time, it would have been hard for him to escape under that divine sense.
Thus, he and the ancient Primordial Chaos family ended up entwined in karmic ties and grudges. Hence, regarding his grand wedding and the Primordial Chaos family's apparent movement, Chu Mo wasn't surprised.
