I became a heroine who dies during the protagonist’s awakening event.

Chen Sansi traveled back to the chaotic end of a dynasty, thankfully with the hardworking system by his side. He originally wanted to hunt to earn money and someday go to the Martial Arts Hall to learn some basic fist and foot techniques, aspiring just to be an ordinary rich man. Yet, fate had other plans. With officials imposing heavy taxes and the Martial Arts Hall bullying the citizens, he had no choice but to enlist in the army to survive, becoming an archer. From “archery (entry-level),” he worked tirelessly up to “operating a ten thousand weight bow, where arrows cannot be dodged,” taking the heads of enemy generals from a hundred miles away! From “basic soldier’s spear technique,” he worked tirelessly up to “National Guardian Dragon Spear, growing more valiant with each battle,” standing firm with a spear on horseback, alone turning back the Enemy Army of a million! Years later, Chen Sansi, having campaigned in the south and battled in the north, was truly invincible under the heavens, commanding two hundred thousand of the Iron Cavalry. Watching his subordinates forcibly ascend him to the throne and become emperor, he felt quite helpless: ’You... you have really caused me trouble!’
