In the winter of the third year of Da Zong's reign, heaven and earth share the same sorrow. The iron cavalry of the Tiezhen clan in the north invaded the border through snow, and the Zhenxi Army was trapped in the border city, and their food and grass were about to be exhausted. In the court, Fu Wang Zhao Yan colluded with the black scarf pirates to rebel, and they attacked seven cities in a row, and half of the country was on the verge of collapse.
Lin Fu, a modern social animal, died suddenly due to overwork and accidentally traveled through time to become an infantry archer at the Huxipu Township Beacon Tower. The broken platform is covered with snow, the rusty spear is cold, surrounded by weak comrades, and in the distance are the enemy cavalry glaring at them - according to the remaining memory, this beacon tower will be crushed by Tiezhen's vanguard in half a month, and no one will survive.
In a desperate situation, Lin Fu relied on modern knowledge to improve defenses and make simple firearms, and narrowly survived the first enemy attack. But this is just the beginning: there are few reinforcements in the border town, King Fu's rebels are pressing forward step by step, and there are even unknown secrets hidden inside the beacon tower.
On the one hand, it is the responsibility of guarding the border to protect the country, and on the other hand, it is the instinctive desire to survive in troubled times. With a broken bow in his hand and a ruined wall behind him, could Lin Fu find a way out for himself and his comrades in this deadly situation of internal and external embarrassment?
