Lord, I Have an Unlimited Exchange System

[Lord Text] + [National System] + [Travel] + [Slow Heat] + [IQ Online] Didn't they all travel through time? I wonder if I am the destined protagonist? Main character? Forget it... Do I, Lao Zhu, admit that you are the protagonist? Haha, is it just you, Zhu Yuanzhang? Even if Qin Shihuang comes! "Who is calling me?" Holy shit! Qin Shihuang is really here... "Your Majesty!" "Your Majesty!" … Liu Bang, Li Shimin, Zhao Kuangyin, Zhu Yuanzhang, and Liang Meng all knelt in the main hall. "Liang Meng... I heard that you want to replace me?" "Your Majesty, you must have heard wrong. I never wanted to replace you." Oh? I just want... To let Da Qin change his surname. What surname should I change to? Liang! Is it really cool? Haha, of course it's my Liang Meng's Liang!
