Double Red Cannon, also known as "cross-river savior" and Xiao Shuanglong, was first seen in the manuscript of Shen Zhiyi, a famous Wenzhou writer, and was popular in Jiangsu and Zhejiang provinces in the early days. The double red cannon is a very complicated and changeable Jianghu endgame. The red side attacks and assassinates again and again, and the black side needs to be careful to deal with it before it can crack the law of taking off its hat. The fly in the ointment is that the black side has speed and regularity.
