Well, that was certainly ugly.
chessboard stratagems. The unifying theme of Lian Po's fighting style so far seems to be that he's completely unorthodox, and not remotely concerned with fighting in a way some of his contemporaries might call honorable. Assassination, smokescreens, all's fair in war for these guys - and as Lian Po himself tells his puppet supreme commander, Xuan Feng doesn't have the pride of most military commanders. When his job is done, he happily retreats. Xuan Feng's role wasn't to win the war - it was to take the next step in softening up the Qin army, picking up where Lun Hu left off. And he seems to have picked off about 80% of the first and second waves of Qin forces by his own experienced estimates - I'd call that pretty softened up.
Mountain Kingdom soldiers (at last) - Xin does manage to do one thing that Xuan Feng didn't plan for, and comes within a few feet of eviscerating him with a spear. But it's a hollow victory, and the devastation would have been even worse without Qian Lei's modestly successful plan to use sound to confuse the Wei archers. It's bad enough as is - Xin managed to use up a pretty good chunk of his new army on the very first day of battle with them.
