When the artillery barrage ceased, the walls of Gate City were already barren, as clean as if licked by a dog. The cannons that Zhao Army brought this time were completely destroyed. Wei Yuan surveyed the area and, seeing no stragglers, felt satisfied.
The one commanding the artillery in this battle was Deputy General Lu Yu. He flew to Wei Yuan's side and said, "The enemy is likely hiding under the inner city walls, which is a dead zone for our firing range. We can initially shell the inside of the border, forcing them to take cover under the walls. Then, we advance our formation, adjusting the cannon muzzle at a distance of two li from the walls, and use indirect firing to target the enemies behind the walls. They will be caught off guard and suffer heavy casualties."
Wei Yuan gazed at Han Yang Pass and said, "No cover fire, just a few shots at the Gate City garrison, a sporadic barrage to scare them is enough."
"But cover fire can severely damage the Zhao Army."
