Wei Ying has Lan Zhan, and he has A-Yuan, and with his usual generosity, he thinks of a way to give Jiang Li and Jin Zixuan (who have been trying in vain for children for five years) a child of their own. As long as Lan Zhan is okay with it, of course. (Lan Zhan is not okay with it, but he says yes. Lan Zhan just can't say no to Wei Ying, not even when it leads to holding his heat-drunk husband while another man takes him.)
