Although the battle had just started, the weakness of Tang Zhong's defense line was already obvious. It seemed like a good thing that the defense line was too long. No matter where Zhao Hai attacked, the others could support him. They could even attack Zhao Hai's flanks and back. However, at the same time, this weakness was too obvious. At every point of the defense line, there had to be some defensive equipment, like a bed.
If Tang Zhong and the others were in the back, there might be no problem with his arrangement. This was because they could rely on a large rear to defend the city. Every point could be equipped with enough defensive equipment, so there would naturally be no problems defending the city.
