The night serves as the best cover, and the special forces of the Tang Army infiltrate the city, penetrating swiftly. They take out the checkpoints and then easily reach the position of the Qin Army's command center.
There's no other way—firstly, the Dahua region has way too many spies for the Tang Army, who can provide ample and accurate intelligence to the battle forces of the Great Tang Empire.
On the other hand, the electronic traces of the Qin Army are too significant. A random scan can locate the places with the most electronic signals. The reason for not attacking immediately with anti-radiation missiles like at the beginning is due to two reasons.
The first reason is that the Qin Army is somewhat on alert. They try to keep the telecommunications room and radar a bit further from the command center to ensure they won't be wiped out by a single missile.
