The Marquis estate's second young lady, Jiang Lin, is the ultimate darling of the entire family. Possessing overwhelming combat strength yet a pure heart, anyone who crosses her meets a bitter end. A biased grandmother returns with the second uncle's family, coveting the Marquis estate's power, attempting to snatch away her engagement to Prince Jing, and even berating the entire primary household as deserving to die. Simple-minded and fiercely action-oriented, Jiang Lin immediately brandishes her sword, intending to enter the palace to assassinate the emperor and end everything in one stroke via execution of the nine familial clans, terrifying the entire household into a panicked block. Who would have expected that she is actually the emperor's Shadow Guard Eleven, who achieved dragon-ascending merits. Facing the greedy second branch and the biased grandmother, Jiang Lin wields absolute strength to protect her family, crushing the other side's schemes, and finally marries Prince Jing in grand style, allowing the Marquis estate's primary branch to finally hold their heads high.
