His Understanding Is Incredible, from the Frontier Army to the Human Emperor

The fifteenth year of Taiyong in Great Chu Autumn. The demon clan from the north went south to attack Youzhou in large numbers. At this time, Zhang Fan happened to travel across time to a soldier of the Youzhou Frontier Army, a cannon fodder guard. The sergeant next to him handed him a secret book and a hundred-forged long sword, "The secret book just handed out by the superiors, there are still two and a half hours to carry out the mission, so just take a look at it and learn a little bit." Zhang Fan looked through it once, and a line of words appeared in front of him: [Demon-killing Sword Technique (Grandmaster): 0/10000, entry level. Cut with a knife: [Demon-killing Sword Technique (Grandmaster) +1] [Demon-killing Sword Technique (Grandmaster): 1/10000, entry level. After eight thousand cuts: [Demon-killing Sword Technique (Grandmaster): 8000/10000, great success. The mission time had come. Looking at the stagnant proficiency, Zhang Fan had no choice but to go and kill the enemy. Who would have thought that killing a demon with one sword would actually drop "+999" proficiency. After a few sword strikes, the entry in front of you changed: [Eighteen Swordsman Killing Demons (Blood Coagulation): 1/1, perfect. "What, you said that there was a pawn in that group of cannon fodder who beheaded the big demon?" "Promoted to centurion!" … Some years later Zhang Fan, who had become the king of Youzhou, stood on the wall tower, looked at the demon and sighed: "I don't want to be granted the title of marquis, I hope the sea will be peaceful." Soon After receiving the news that the royal family and the demons were working together to bring trouble to the world, his subordinates all knelt down and begged him to bring happiness to the people of the world. Zhang Fan sighed softly: "I didn't intend to compete, but the people are suffering."
