Chu Suifeng and Situ Gong realized they had been somewhat careless.
In the deep autumn of the Northern Land, the temperature at night is particularly low. There has been no moon these past few days, they hadn't expected Billy and Bayal to be so reckless as to disregard the cold and the safety of the North Country soldiers to launch a surprise attack under the cover of darkness.
Luo Cheng was even more frustrated, he had stood guard on the city wall for several nights in a row, and only yesterday he had replaced someone to be on duty. He didn't expect such a significant event to happen.
"We beg for punishment." The two guards of the city knelt down in shame, unable to lift their heads.
The enemy had crossed the river overnight and reached the bottom of the city, and they had not noticed it at all.
