**Tempered with Iron and Blood**: The young general Liu Yan first showed his talents in the bloody battle of Mang Mountain. He broke through the formation with an eight-edged plum blossom hammer to capture the general, and won the reputation of "Silver Hammer Taibao". However, he was jealous of the prince because of his outstanding achievements.
- **Shocking Change**: King Lanling was killed by a secret arrow when he was pacifying the Khitan. Prince Gao Yin purged his old ministry after he ascended the throne. Liu Yan, who was stationed at Feihuxing, saw with his own eyes the murderous intent in the eyes of the eunuch who passed the imperial edict.
- **Undercurrent**: Liu Yan took control of the Taihang Salt Channel in the name of suppressing bandits, placed an informant in Zhending Mansion, uncovered the corruption network of the Minister of Household Affairs through the case of adulteration of military grains, and turned the evidence into a life-saving talisman.
- **The Beacon Rises Again**: The Khitan's 100,000 cavalry went south, and Liu Yan was ordered to do so in danger. Outside Zijing Pass, they used the Fire Ox Formation to defeat the enemy, but the supervisors deprived them of their food and grass and secretly reached a horse deal with the Taiyuan Li family.
- **Bloody Edict**: The new emperor's offer of marriage to the princess was actually a plan for murder, and Liu Yan used his plan to trigger a mutiny in the imperial army. On the night of the Suzaku Gate Incident, eight hundred Xuanjia troops made a surprise attack on the Yedu arsenal.
