Boom!
Two explosions rang out in succession. The ground shook twice, and the neighboring residence and Qian Residence's second perimeter wall collapsed.
Kill! Black clouds moved through the breach and swiftly surged into Qian Residence.
Cao Yiyan charged within the formation, his mind still calm.
Qian Residence was the core target, but any guard or yamen soldier with a functioning brain who entered first would search the entire estate.
This did not even need saying. Anyone who failed to understand it could be classified as an idiot.
But the surrounding residences could not be thoroughly searched in a short time.
So Cao Yiyan used hidden troop tunnels to connect them.
Marquis Guo Deng of Dingxiang had the "Earth-Twisting Dragon" and the "Sky-Flying Net"—digging deep trenches and covering them with earth and timber, allowing men and horses to pass as if walking on solid ground; once enemies entered the encirclement, the mechanism was triggered, causing them to collide and crash into one another, and in an instant, more than ten li of ground would cave in.
Naturally, Cao Yiyan could not imitate this within the Capital City and dig tunnels stretching for more than ten li.
But the underground wells and passages had already extended in all directions. Digging through another few hundred paces was still possible.
Several walls collapsed before his eyes, revealing a flat, straight road with nothing left to obstruct them.
Kill—
Six hundred men shouted in unison. The armored soldiers of Qian Residence changed color at the sound, while only Su Ziji wore a faint smile.
Yet inwardly, he was startled as well.
With a thousand men attacking from front and rear, it truly was foolish to personally take the field. One careless step, and the boat could capsize.
*Thus, a son of a thousand gold coins
