到李密打下洛口仓，进逼东都洛阳，炀帝特令王世充统帅大队人马，到洛口抵御李密，前后交战一百多次，还不分胜负。
及李密攻陷洛口仓，进逼东都，炀帝特诏世充大发兵，于洛口拒密，前后百余战，未有胜负。
When Li Mi captured Luokou Granary and approached Luoyang, the Eastern Capital, Emperor Yang specially ordered Wang Shichong to lead a large army to Luokou to resist Li Mi. They fought more than 100 battles, and neither side gained the advantage.
