Datang: After Li Er Found Out About My Immortality

Lang Yu found out that he had traveled to the Tang Dynasty and had the buff of immortality. So in terms of speaking to Li Er's heart, Lang Yu was ranked second, and Wei Zheng didn't dare to be ranked first. "Don't worry about killing your eldest brother. If you don't kill him, he will kill you too!" "Old Li, you actually want the princess to make a marriage. Do you know that if you don't cede territory, pay indemnity, pay tribute, or make a marriage, the emperor will guard the country and the king will die in the country." "Lao Li, how old is your daughter Changle? Why don't you marry me? Of course, you have to let me see it first. If it looks ugly, then I won't want it. " "Old Li..." Whenever Li Er's patience with Lang Yu was about to break through the limit, a piece of information that could change the fate of the Tang Dynasty was sent to his desk by Lang Yu. Refined salt purification technology, grain production increase plan, research and development and application of flintlock guns... Many years later, Li Shimin looked at the vast territory and felt complacent. Lang Yu: "Old Li, are you complacent after conquering such a small amount of territory? Do you want navigation charts for North and South America and Australia?" Li Er: "..." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
