In 1107 Goryeo dispatched five large armies led by Yoon Gwan to Helandian. They destroyed a hundred Jurchen villages and built nine fortresses there. After a one-year battle, the Wanyan army won two fortresses and eliminated Goryeo reinforcements. Goryeo and the Jurchen achieved settlement and, as a result, Goryeo withdrew from the occupied areas.
 * Under Wanyan Wuyashu's order, Shi Shihuan (石適歡) led Jurchen army of the Tumen River basin, subdued Jurchen in Helandian and advanced southward to chase about 1,800 remnants who defected to Goryeo. Goryeo did not hand them over but sent Im Gan (林幹) to intercept the Wanyan army. However, Shi Shihuan defeated Im Gan north of the Chŏngp'yŏng wall and invaded northeastern frontier of Goryeo. Goryeo dispatched Yoon Gwan (尹瓘) but lost a battle again. As a result, Wuyashu subjugated the Jurchen in Helandian.
