The Country Will Be Destroyed in Seven Days! You Want Me to Take over as Emperor?

[Avatar history + Invincible cool text + Decisive killing + Arsenal system + World hegemony] Gu Lingtian traveled through time and became the eighth prince of Yong Dynasty. At the beginning, he took over the throne from death row and became the emperor. Only then did they learn that the Supreme Emperor had fled south with Manchu officials, leaving only a few thousand remnant soldiers behind. He was asked to resist the 200,000 Northern Barbarian cavalry who would approach the city after seven days. The desperate situation unlocks the population hegemony system. The more people under your jurisdiction, the more points you get every day. Points can be redeemed for rifles, heavy machine guns, mortars and other hot weapons! On the first day, shots were fired to frighten the imperial guards, and the civil servants were beheaded in court to persuade them to surrender. The next day, military pay was distributed in full to stabilize military morale. On the third day, after the emperor fled south, he left behind several beautiful concubines. … In seven days, Gu Lingtian formed a new firearms army and defeated the Northern Barbarian cavalry head-on. The foreign enemies had just been pacified, and the Supreme Emperor sent people to convey the decree in an attempt to take back the imperial power. Gu Lingtian looked at his army of tens of thousands of hot weapons and said coldly: "I am guarding the country with my own strength. It is not his turn to point fingers in this country!" The eunuch cursed loudly: "Do you still have ancestral system in your eyes?" Gu Lingtian said loudly: "Only the weak tell the rules, the strong make the rules!" From then on, everything the sun and moon shine on is my soil! Wherever the military front arrives, all nations will bow their heads, and all the world will be vassal!
