If it had been any other commander, Hulaoguan Pass would have been breached at the first opportunity following the field battle.
In this battle, Li Hongyun had indeed won against Lord Qin.
From the current situation, the next move was actually quite predictable.
With the fall of Hulaoguan Pass, Dou Jiande's massive army could march towards Luoyang City.
And no matter how capable Lord Qin was at fighting, his only option then was to retreat.
For Luoyang City had not yet been conquered, and the Liang Army could hardly afford to split its forces to engage in open field combat with Dou Jiande's mighty army.
If they did so, although Wang Shichong inside the city was already a frightened bird, he would definitely launch an attack from the city, pincering them from both sides.
Under those circumstances, the Liang Army, being at an absolute disadvantage in troop strength and without a defensible position, would undoubtedly lose the battle.
