So does he not like Dual Cultivation? He seems to never think of it even when he has girls willing. His physique is built around it yet it. Even in the first world it was only used near the end. Then he left the girls behind.
He does enjoy dual cultivating, but the effects are better when he genuinely cares about his partners. And it was due to special circumstances that he had even got with his girls. He had already figured out that ordinary dual cultivation with random women is far inferior to the connections he already has. And the reason Xiang is rushing through this planet is so he can have the power to protect his girls and soon reunite with them.
