In the end, some key members of the Han Mansion were bound to be under his control; by then, the already grown Han Mansion would be just the help he needed to break free. Once freed, he'd exterminate the entire Han Mansion.
As long as he could get out of the grand formation, he'd quickly return to his peak. With his strength, although he couldn't provoke the several Sacred Lands of Qianyuan Divine Province, wasn't dealing with the little Han Family as easy as capturing them in the palm of his hand?
This was Emperor Changfeng's plan, and he called it: fattening the pig.
When the Han Mansion, this pig, had been fattened, it would be time for his reckoning, a ruthless harvest to avenge the hatred festering in his heart.
As for whether the Han Mansion would grow beyond his control, Emperor Changfeng had considered this, but he did not care.
Because it was impossible for them to grow beyond his control.
