Pang Tong proposes that Cao Cao applies his scheme of the connected boats, a plan implying that Cao Cao uses iron chains and bolts to tie boats together into rows of thirty or fifty boats. Even during the strongest wind and exposed to the greatest waves, the boats will go steady, and they can proceed unconquerably towards the Southland, not even Zhou Yu being able to stop them. Cao Cao falls right into Pan Tong’s trap. After Pan Tong leaves Cao Cao, he is grabbed by Xu Shu, who wants Pang Tong to make a plan for his escape.
龐統獻連環計要曹操把水師船隻或三十隻或五十隻首尾用鐵環、大釘相釘，風浪再大船也不會晃動還能當著無敵奇兵沖往江東，周瑜抵擋不住，曹操中計。龐統走後在江邊被徐庶抓住，要他教傳自己的脫身之計。
