The bathtub wasn't very big to begin with, so Ning Fan couldn't possibly continue to stay in it. Moreover, bathing in a fish tank with two beautiful women who had stripped naked, and crucially, he couldn't move.

Xu Rongfei was right, the effects of the medication on Ning Fan had indeed passed. Earlier, when Xu Rongfei had left, Ning Fan had used his strong willpower to recover a bit and, enduring the agitation in his body, he had gone to the bathroom.
Of course, he wasn't there to take a bath, but to avoid Qin Xianglian. However, he had not expected that soaking in water would enhance the effect of the Joy Powder so surprisingly well that the drug in Ning Fan's body had dissipated by more than half.
But even though it had dissipated by more than half, there still were effects of the drug in Ning Fan's body.
