In 1634, the second Qing emperor Hong Taiji (r. 1626–1643) gave Eidu a posthumous rank of viscount, which Ebilun immediately inherited but lost in 1637 after he tried to interfere in a trial involving his niece. In 1643 Ebilun followed Nurhaci's seventh son Abatai in forays inside North China and was credited with the capture of several towns. In 1645 and 1646, after the Qing had defeated the Ming dynasty and made Beijing their capital, Ebilun served under Lekedehun in campaigns to dislodge Ming loyalist He Tengjiao (何騰蛟; 1592–1649) from Hubei and was rewarded with a minor hereditary rank. Yet his position was not assured. Because he belonged to the Yellow Banners, Ebilun was treated with suspicion by Dorgon (the Prince Regent of the young Shunzhi Emperor), whose power base was in the White Banners.
