From what Youlan told her, Yumo found out that she was planning to hurt Mengxi.
However, at this moment, more than protecting Mengxi, Yumo's utmost goal is to save her own daughter.
Moreover, based on the current situation, the soul petal would guide her to Youlan's physical body, and Yuan'er is beside Youlan's body. If everything goes smoothly, when Yumo rescues Yuan'er, she should also be able to control Youlan.
Although Yumo was also worried that Youlan had other ways to harm Mengxi, as long as Youlan did not personally lay hands on her, Yumo believed Mengxi's safety could be ensured. After all, that girl possesses the divine power bestowed by the goddess.
Luminous Royal Academy is located near the capital of Red Leaf Empire. If Youlan sends people to hurt Mengxi, the Church and the strong warriors of the Red Leaf should be able to confront them.
"They... should be able to protect Mengxi."
