I'm a Good-For-Nothing Prince, and I'm Attracted by a Female Sword Fairy

The good-for-nothing prince was suffering from a terminal illness. He left the capital for ten years to find medicine, but when he returned he was at the top of the world. She was granted a marriage by the emperor and married the legitimate daughter of the Hou Mansion. Unexpectedly, the legitimate daughter of the Hou Mansion, which the world avoided, turned out to be a female sword fairy. The kings competed for the throne and spent many years planning to win over hundreds of officials. Jiang Lin didn't want to seize the throne, but the brothers killed each other and bullied each other too much. He entered the court alone, took out the precious medicine, and attracted the generals of the army to join him, overwhelming the kings. Why kill Jiang Lin? Kings: Use the power of the imperial court to suppress people, forcing them to go to the border and enter the battlefield to fight. Jiang Lin: I have an army of millions, thousands of masters, and no one can stop me! Kings: lure away the guards and use the stronger ones to assassinate them. Jiang Lin: I walk the high road alone and am the best in the world, unrivaled! Kings: I sacrifice my own head Jiang Lin: Good!
