Mekia's goal was to gauge Olivia's strength/power. The phrase they used during the meeting was "to investigate and test." Therefore, they sent only one general. Logically, killing Olivia (IF successful) would actually harm Mekia itself. They needed Farnest Kingdom to erode the Empire's power. If Farnest lost Olivia, the Empire would regain the upper hand.
