《宋金風雲錄》E2：海上之盟 詳細還原宋徽宗是如何一步步作死的。How Song Huizong died step by step

岳飛從軍之後參加的第一場大型戰役，北伐遼國，卻以失敗告終。那麼北伐遼國是怎麼回事呢？原來在宣和二年，宋徽宗這個好大喜功的皇帝為了實現收復燕雲十六州的偉大藍圖，與金國簽訂了臭名昭著的海上盟約，盟約規定，宋金同時出兵攻遼。才有了後來的所謂北伐。
The first large-scale battle Yue Fei participated in after joining the army, the Northern Expedition to the Liao Kingdom, ended in failure. So what happened to the Northern Expedition to the Liao Kingdom? It turned out that in the second year of Xuanhe, in order to realize the great blueprint of recovering the sixteen prefectures of Yanyun, Song Huizong, the overjoyed emperor, signed the notorious maritime covenant with Jin. The covenant stipulated that Song and Jin would send troops to attack Liao at the same time. Only then did the so-called Northern Expedition come into being.
