This surprise attack is incredibly challenging.
Even with Gu Quan leading the troops personally, he has to make thorough preparations.
—The troops need not only to be elite, but more importantly, their resolve must be unwavering.
Completely different from the previous two attempts.
Whether it was Gu Xiao or Gu Chen.
The troops they commanded were personally trained by the Gu Clan, and their obedience far exceeded others.
This time, it's entirely different.
He must make comprehensive preparations, leaving no room for errors.
...
In April of the second year of Wude.
Li Shimin officially launched an attack towards Gaozhi.
His momentum was overwhelming, completely setting the stage to subdue all of Longxi with one battle.
Especially with Gu Yan and several members of the Gu Clan among them.
This invisibly boosted the Tang Army's momentum!
It's been too long!
It's been too long already!
