[Li Er, are you kidding? Now there is a heavy snow in northern Turks, you send troops there, not a big defeat!] Li Er: "Ke'er, Hedong road is in a severe drought. Now there are many victims everywhere. How to deal with them?" [Li Er, I'll tell you, can the potatoes planted in my backyard yield thousands of kilograms per mu?] "Ke'er, I think the vegetables in your backyard are very good. Come on, dig them all away!" Li Ke: many years later, Li Ke found that the Tang Dynasty was becoming stronger and stronger, and Li Er was rejuvenated in his second spring and became extremely young... Li Ke: No, it shouldn't be like this according to the historical script. How do I feel that the immortal position is getting farther and farther away from me one day, Li Er: Ke'er, I think you look like a great emperor! The throne will give way to you Li Ke:??? I don't want it note: imagine the Tang Dynasty, overhead history! (adults, please read this book with minors!)
