I'm Sorry to Distribute the Frontiers, but I'll Just Build an Empire.

When Chu Xiao woke up, he found that he had traveled through time and became the eldest prince of the Great Xia Dynasty. However, before he could enjoy the glory and wealth, the emperor died and the imperial edict was usurped. He who was supposed to inherit the throne was plotted by the insidious second prince and the powerful eunuchs and was sent to Beijiang Pass, a bitter and cold place in the north. There were only more than a hundred old and weak soldiers there, the city walls were in ruins, bandits were rampant, and the Huns plundered them every year. It was a desperate situation. The second prince Chu Hui pretended to be benevolent and righteous, euphemistically calling him "Brother Experienced Emperor", but in fact he wanted to kill someone with a borrowed knife and let him die on the border. However, Chu Xiao was not panicked at all, and was even ecstatic! Because at the moment he left Beijing, he awakened the heaven-defying system - the cross-time and space mall! Food? Purchase! Arms? Purchase! Modern steelmaking technology? Purchase! German mechanic equipment? Purchase! Tanks and cannons? Buy them all! So, under Chu Xiao's management, Beijiang Pass, a cold and barren place, turned into a steel fortress in just one year! The trade routes are prosperous, the people are rich, and the army is elite. Even when the Huns' cavalry invaded, they were bombarded by machine guns and cannons and made their lives doubtful! The second prince thought that Chu Xiao would definitely die, but what he was waiting for was - "Report! Great victory at Beijiang Pass! His Highness led the army to annihilate the Xiongnu's 30,000 cavalry!" "Report! The tax revenue in Northern Xinjiang is three times higher than that in Jiangnan!" "Report! His Highness... Proclaimed himself emperor?!"
