Method: Take down the juggernauts first as they are easy to take out. You can
kill the officers in the central fort but do not kill those in the western
one or the plan will fail. After 4 minutes have passed, Xun You (䤿) will
start moving after Zhang He talks. Escort him to Yuan Tan (åÍæ) and Tan will
defect.
After some time, Yuan Shao will talk to Jiang Wei and Jiang Wei will go
towards Yuan Xi (åÍê¤). Defeat Jiang Wei before he reaches to Yuan Xi. Once
you do that, Jiang Wei will talk to Yuan Xi and Yuan Xi will defect to your
side. Item report will appear soon after.
