Three Kingdoms: Liu Hong Is My Big Brother

Protagonist: Liu Cheng, a modern graduate student in history, accidentally transmigrates to the late Eastern Han dynasty and takes over the body of a declining member of the imperial clan in Jizhou. In truth, he is the younger brother of Emperor Ling of Han, Liu Hong. As a child, he was secretly sent to Jizhou to be raised because of court intrigue, and was publicly described only as a distant relative of the imperial family. - Golden finger: - System: Its functions are simple, with the core feature being a “growth panel” that displays the protagonist's and his subordinates' attributes and skills. There is also a small world inside his mind. “The entrance to the small world is in the protagonist's mind,” and he can place it wherever he wants. If he doesn't bring it out, it remains in his sea of consciousness. This is an extremely classified secret, but anyone who has visited the small world and come back will be one hundred percent loyal to the protagonist forever and will never betray him. There are no complicated missions; basic functions unlock as the protagonist's power grows, such as adjusting the flow of time in the small world and improving the fertility of its land.
