Tang Dynasty: the Poisonous Plan of the Emperor, Li Shimin Advised Me to Calm Down

Li Guangming traveled through the Zhenguan period and became a counselor in the Tang Dynasty. I thought I would survive in the Tang Dynasty for the rest of my life, but I didn't expect that I would awaken the Poison Master System and reach the pinnacle of my life because of my repeated poison tricks. Li Jiancheng: "How should we deal with Gu's second brother?" Li Guangming: "Poison can be used." [Ding, the system rewards are immune to all poisons! Li Shimin: "How to ensure long-term peace and stability in the northern grasslands?" Li Guangming: "You can throw the corpses of death row prisoners and rebel soldiers into the water source of the prairie people. After the prairie people drink it, they will all have a healthy body." [Ding, the system rewards one thousand catties of corn! Wu Zetian: "How to become the emperor of the Tang Dynasty?" Li Guangming: "If you strangle your daughter to death and poison your son, your dream will come true." [Ding, the system rewards the Snow Dragon Rider! Li Shimin was numb: "Your strategy is too vicious, but you have made many great achievements, so I will make you the Emperor of the Tang Dynasty." But the ministers were puzzled as to why he could become the imperial master at such a young age? Li Shimin: "Because he is calm." Li Guangming: "It's more because of the system."
