Ren Baqian, the empress, as well as the over a hundred winged cavalry warriors waited from noon all the way until late at night. It wasn't until the next morning that a unit actually arrived. As for the other unit, there was still no sign of them.
As a matter of fact, this unit of the winged cavalry didn't really encounter any trouble along the way with the exception of running into a convoy, which was about a thousand people strong when they were rushing over. Some of them were killed while more than half of them managed to escape.
Ren Baqian suspected that the other unit might have run into some trouble on the way here. For example, just like the unit which just returned, they might have run into a large number of Great Xia's elite troops and so on. He was afraid that they would be some sort in danger. If they continued to wait, he feared that the Great Xia troops would have already deployed after obtaining this information.
