"Beat me up?" Yu Lin Bloodhawk asked in bewilderment. "Why would you beat me up?"
"You're here with me, but you're thinking about another woman. Don't you think you deserve a beating?" Alleria said.
"...Sylvanas is your sister... not another woman..." Yu Lin Bloodhawk said.
"Even if she's my sister, I still want to beat you up!" Alleria said.
...Yu Lin Bloodhawk shut his mouth. Women were far too fickle. He had no way of predicting what a woman was thinking, and guessing would get him nowhere, so he decided the smartest course was to keep quiet.
Ten days after Yu Lin Bloodhawk and Alleria had reluctantly parted, Xingluoge finally arrived, escorting three captive Death Knights.
When Yu Lin Bloodhawk saw the three captive Death Knights, he understood why they had taken so long to arrive. With prisoners in tow, they obviously could not fly back on Gryphons. They had to travel overland, and walking hundreds of kilometers was hardly going to be quick.
Why had Shidewa and Xingluoge brought these three prisoners? Because they felt the Death Knights were simply too powerful. If only one or two Death Knights had been that strong, it would not have mattered much. But when every Death Knight was so powerful, they had no choice but to take them seriously. These were enemies they would have to face, after all.
Still, no matter how powerful someone was or how absurdly strong their class might be, they had to have weaknesses, didn't they? Shidewa and Xingluoge had no time to investigate, but the old Mages at the War God Temple in Quel'Danil certainly did. So, after discussing it, Xingluoge and Shidewa had brought all three prisoners over.
Know yourself and your enemy, and you would never lose a battle. They understood that principle well
