Crying Li Er, I Will Continue the Tang Dynasty for a Thousand Years

Li Yi traveled through the Tang Dynasty and became the silly son of Prince Li Chengqian. He was only six years old and weighed sixty kilograms. Fifty-nine kilograms is a traitor! At the beginning, the emperor's grandpa Li Shimin was so angry that he went into shock on the spot and accidentally activated the [strongest cheating system]! The rules of the system are astonishingly simple: as long as Li Shimin's mentality is broken and his emotional value explodes, all kinds of treasure chests can be opened! "Grandpa, don't feel guilty about the Xuanwu Sect. The seniors said in their dreams that they forgive you!" "Grandpa, I've been reading history books recently. Why does it say that your position is incorrect?" Li Shimin was so angry that his blood pressure soared, and the imperial doctor was on call in shifts. However, Li Yi happily prescribed [Hybrid Rice], [High Strength Cement], [Penicillin], and even [AK47 Design Drawing]! Civil servants called him evil, but military generals regarded him as a living treasure. When the Turkic army pressed on the border and everyone was helpless, Li Yi walked up to the tower carrying his newly opened "toy". At that moment, the whole world went silent. While Li Shimin was covering his chest and taking Jiuxin Pills, he tearfully issued an edict: "Pass the edict! Give my grandson the title of king!"
