Lin Hao, an ordinary 996 programmer, his biggest hobby is to play the Three Kingdoms game after get off work. When he woke up, he found that he had traveled through time and became Liu Bei and Liu Xuande, the most miserable protagonists of the Three Kingdoms! The beginning is a battlefield, with injuries on his body, and he is about to be hacked to death by the soldiers! At a critical moment, a golden finger named [Three Kingdoms Sign-in System] suddenly activated and saved his life. What did the system give him? Farming techniques, craftsmen's manuals, farming orders... Wait, isn't this script wrong? When other people traveled through time, they had magical weapons and an army of millions. How come it turned into a farming simulator when he came here? What's even more outrageous is that the system also comes with a [harem system], telling him: as long as he captures the beauties of the Three Kingdoms, he can get attribute bonuses! Mi Zhen, Gan Mei, Diao Chan, Zhen Mi, Cai Yan... None of them can be missing! Well, since God asked him to be Uncle Liu Huang, then he would reluctantly—— Farm first, then train troops, and then... Wait, Cao Cao is coming? Yuan Shu is also watching with eager eyes? Lu Bu, a slave with the third surname, also wants to join in the fun? Lin Hao was about to cry but had no tears: "I just want to be a salted fish!" System: "Sorry, host, you have automatically accepted the main mission - 'Kuang Fu Han Room'." Lin Hao: "..." Can I return it?
