Sent to the Frontier, I Signed up for an Army of Millions of Gods and Demons!

"You are asked to marry the daughter of the general who is holding the country, and you dare to refuse the marriage in public? Go to the Demon Town Pass and live or die!" In the Daqian Dynasty, in the Jinluan Palace. Qin Yuan, who had traveled through time, had just opened his eyes when he heard the roar of his father. After merging the memories, Qin Yuan almost cursed! Chu Qingcheng, the daughter of the general who ruled the country, was the most beautiful woman in Daqian and held great power. Although he has a strong personality and wants to be married to one person for the rest of his life, and will never take concubines, he still wants to be good-looking and powerful. How could this former soft-boiler refuse to eat for the sake of so-called "macho chauvinism"? It's okay now. I just traveled through time and was demoted to the demon-suppressing pass to be cannon fodder! Fortunately, [God-level sign-in system] is activated! "Ding! Sign in at the head of Zhenyao Pass, and you will be rewarded with 10,000 [Big Snow Dragon Riders]!" "Ding! Sign in to the Monster Corpse Mountain and you will be rewarded with a [Ji Dao Emperor Sutra]!" "Ding! Sign in at the Great Wall of Despair and be rewarded with the god-level general [Killing God Bai Qi]!" A few years later, the demon tribe's millions of troops came out in full force, and the Daqian Dynasty trembled. Chu Qingcheng, the daughter of a powerful minister, was ordered to rush to the aid of Demon Suppressing Pass. She expected to see Qin Yuan begging for mercy, but she was horrified to find that—— Outside Zhenyao Pass, the Beijing view towers into the clouds! All demons bow their heads and surrender! The prince who was known as the most useless prince was wearing a black dragon emperor's robe and sitting on the throne, with millions of gods and demon cavalry under his command so fierce!
